  TORCHE   ELECTRIQUE.   



   La présente invention concerne les torches électriques,et spécia- lement celles à tête en équerre. 



   L'invention a pour but de procurer une torche de ce type ayant un bottier en matière plastique construit de façon à être indéformable et incassable dans des conditions d'emploi sévères comme un froid extrême et une chaleur   extrême    séche   ou humide. 



   L'invention a aussi pour but de procurer une torche du type men- tionné, composée   d'un   petit nombre de pièces simples, et se montrant très ef- ficace à l'usageo 
D'autres buts de l'invention ressortiront de'la description sui- vante ou seront indiqués ci-après. 



   L'invention consiste dans les caractéristiques de construction, les combinaisons d'éléments, et dispositions de parties décrites ci-après. 



   Une des diverses formes d'exécution possibles de   l'invention   est représentée aux dessins annexés, dans lesquels ,

   1-1 arrière .    



   Les figures 7 et 8 sont des coupes en substance suivant les lig- nes   7-7   et 8-8 de la figure 6, respectivement. 



   Comme le dessin le montre, la torche à   tte   en équerre 10 de l'in- vention est composée, dans l'ensemble, d'un bottier de pile 12, une tète   14,   un fond 16 et un dispositif électrique comprenant un interrupteur 18 et divers éléments de la tête et du fond. 



   Bottier de pile.- 
Le bottier 12 fabriqué en une matière isolante moulable comme, par exemple, un produit de condensation phénolique ou de l'acétate butyrate de   cellulose,   est composé d'un corps 20 et d'une tête 22 faits d'une pièce. 



  Le corps consiste en un tube cylindrique creux à fond ouvert muni d'un pas de vis 23 sur lequel se visse le fond. Le corps est pourvu, immédiatement au-dessus du pas de vis, d'un bourrelet circonférentiel 24 de consolida- tion. Un bourrelet semblable 26 est prévu au haut du corps par souci de sy- métrie. Entre ces deux bourrelets, la surface extérieure du bottier est pour- vue de plusieurs nervures longitudinales 28 moulées servant à rendre le bot- tier plus rigide et à lui donner ainsi une grande solidité, tout en mainte- nant ses parois aussi minces que possibles, par souci d'alléger la torche et par économie de fabrication. 



   La tête 22 du bottier comprend un tube cylindrique ayant le dia- mètre du corps 20 et fait d'une pièce avec celui-ci, les surfaces de jonction de la tête et du corps étant arrondies à l'arrière de la tête, en 30. 



   L'avant du tube cylindrique constituant la tête 22 est pourvu d' un pas de vis 32 servant à l'assemblage de la   tête     14.   



   Quoique se trouvant à l'intérieur du bottier 12 de la torche, la paroi inférieure 34 du tube constituant la tête 22 est laissée sensible- ment intacte (fig. 2) et elle relie un   coté   du corps 20 du bottier au côté diamétralement opposé. Cette paroi inférieure 34 constitue une cloison cour- be, concave vers le haut, séparant la tête du corps et renforçant sensible- ment la résistance aux chocs du bottier, le rendant aussi moins déformable aux hautes températures et dans des conditions atmosphériques humides ou sè-   ches.   



   L'intérieur du bottier 12 a une configuration spéciale pour s'a- dapter aux différentes parties du dispositif électrique sans que la solidité ou la robustesse du bottier n'en souffre sérieusement. 



   La paroi intérieure du corps du bottier comporte deux nervures es- pacées parallèles 36 qui définissent entre elles une rainure 38 qui devient un peu plus étroite dans la partie supérieure du corps 20. On notera que les nervures passent le long et sous l'interrupteur 18, renforçant ainsi le boi= tier aux endroits où il est percé et vidé pour permettre le montage de l'in- terrupteur. 



   L'extrémité supérieure de la rainure 38 passe dans une ouverture 40 pratiquée dans la cloison   semi-cylindrique   34 faisant partie de la tête. 



  Immédiatement au-dessus de cette ouverture et au-dessus de l'extrémité de la rainure 38, se trouve un ergot légèrement effilé 42 faisant corps avec le bottier. Cet ergot est parallèle à l'axe longitudinal de la   tête   22 et est relié à celle-ci par une nervure 44 qui s'arrête un peu avant l'extrémité de l'ergot, de manière à constituer une encoche   46   dont les parois sont écartées radialement de l'axe longitudinal de la tête et font face vers l'avant de celle-ci. L'avant de la tête, portant le pas de vis moulé 32 a un diamètre intérieur plus grand que celui de l'arrière de la tête qui fait un avec le corps 20 du bottier. 



   La partie avant évasée de la tête est raccordée à la partie ar- rière par un congé 48 Le sommet du congé interpose un obstacle fixe entre la paroi intérieure 46a de l'encoche   46   et la paroi intérieure   47   de la par- tie avant de la tête 22. Le motif de cette construction sera donné en étudiant 

 <Desc/Clms Page number 3> 

 le dispositif électrique. 



   Pour faciliter le moulage du bottier en une pièce,la cloison semi-cylindrique de renforcement 34 peut être percée d'une ouverture supplé- mentaire 50 dans laquelle se rejoignent les noyaux de moulage du corps et de la tête. Gomme   indiqué,   cette ouverture 50 peut se trouver à l'arrière de la   t.éte.   La cloison est renforcée, à hauteur de cette ouverture, par une nervure verticale 52 qui s'étend d'un côté à l'autre de la,cloison semi-cy- lindrique   34.   Pour renforcer encore mieux la cloison semi-cylindrique et tout le bottier en général, cette nervure est associée, d'une manière décrite plus loin, à un élément du dispositif électrique. 



   Il est préférable de renforcer aussi les extrémités de la nervu- re et ceci se fait en moulant une paire d'attaches 54 entre la nervure et les parties voisines de la tête et du corps. Ces attaches empêchent de plier ou de déformer la nervure 52 en avant ou en arrière. 



   Pour faciliter le port de la torche, le bottier est pourvu d'un crochet métallique élastique ordinaire 56, attaché au bottier au moyen de deux rivets 58 qui traversent des trous dans le crochet et dans le   dos¯du   bottier et dont les extrémités intérieures sont rivées sur une lamelle en acier 60 à l'intérieur du bottier. On remarquera que le bottier est notable- ment renforcé à cet endroit pour mieux résister aux forces déformantes, à l'extérieur par un large contrefort 28 et à l'intérieur par un plat 62. 



   Enfin, le boîtier comporte aussi plusieurs trous et évidements, qui seront décrits   ci-après  pour loger et maintenir divers éléments du dispositif électrique. 



   Le bottier contient   l'habituel   jeu de piles B, glissé dans un manchon fibreux sans fond   64,   de manière que les piles soient connectées en série et que la cuvette en zinc 66 de la pile inférieure soit accessible au bas du manchon, tandis que l'électrode en carbone, métallisée à   l'extrémité,   68 de la pile supérieure est accessible au haut du manchon. 



   La   tête. -   
La tête comprend une bague à lentille 70 en matière plastique avec des taraudages 72 s'adaptant aux pas de vis 32 de la partie avant de la tête 22, Le bord frontal de la bague à lentille a un rebord rentrant 74 qui constitue une base 76 contre laquelle la lentille 78 vient s'appliquer. 



  Cette lentille peut être faite en toute matière transparente,  comme   du verre ou une matière plastique   transparente,   par exemple du méthyl méthacrylate, une résine   dester   vinylique, une résine de vinyl acétal ou de l'acétate butyrate de cellulose. La lentille peut avoir la forme d'un disque plat cir- culaire, comme indiqué, puisqu'elle est associée à un réflecteur parabolique, le mot "lentille' étant utilisé couramment sans qu'aucune de ses faces ne soit courbe. Le rebord rabattu vers l'extérieur 80   d'un   réflecteur parabolique é-   lectriquement   conducteur 82 est pris entre la face arrière de la lentille et le bord frontal de la tête 22, donc derrière la lentille.

   Le réflecteur est monté de façon à constituer avec -une ampoule électrique 84 un ensemble   préfocalisé,,   le réflecteur servant à faire passer le courant d'un pôle de la pile B à l'ampoule d'éclairage. Dans ce but un manchon fileté 86 fait en une matière conduisant l'électricité peut être rivé sur le bout arrière du réflec- teur, l'avant du manchon étant rivé par un repli vers l'intérieur, constituant une butée 88 contre laquelle l'avant du rebord 90 da culot de l'ampoule élec- trique 84 vient   s'appuyer,   Le culot est poussé contre la butée par un bouchon 92 fait de la même matière isolante que le bottier 12. Ce bouchon est fileté et se visse dans le manchon 86; pour faciliter la rotation du bouchon,celui- ci est pourvu à   l'arrière,  sur son contour 959 de rainures 94.

   Le bouchon est percé de part en part dune grande ouverture 96 dans laquelle le culot de 1' ampoule électrique se place librement,le contact central 98 du culot dépas- sant l'arrière 95 du bouchon, de manière à venir facilement en contact avec un élément du dispositif électrique.

  Le fond. - 
Le fond comprend un couvercle de fermeture 100 en la même matiè- re plastique que le bottier 12. Le couvercle est fermé en-dessous par un fond 102, tandis que sa partie supérieure, ouverte, est pourvue d'un tarauda- ge 104 qui s'adapte au pas de vis 23 du bas du corps 20 du bottier. Le ta- raudage 104 est séparé du fond 102 par un espace assez grand pour pouvoir y loger la majeure partie d'une ampoule de réserve 106 placée en travers du couvercle de fermeture, la paroi du couvercle qui entoure cet espace s'épais- sissant de manière à constituer un rebord 108 sur lequel pose la ferrure 110 qui porte l'ampoule de réserve. Cette ferrure, faite d'une seule lamelle mé-   tallique,   consiste en une bride 112 dont les deux bouts 114 sont arrondis de façon à épouser la paroi intérieure du couvercle au-dessus du rebord 108. 



  La partie centrale 116 de la bride est relevée et fendue axialement en 118, pour recevoir une partie du rebord 120 du socket de l'ampoule de réserve 106. Celle-ci est maintenue par deux doigts élastiques 122 découpés dans la bride et formés de façon à serrer le socket   124   de l'ampoule de réserve. La ferrure.portant l'ampoule de réserve est appliquée contre le rebord 108 par un ressort de compression de pile hélicoïdale conique 126, fait en une matiè- re conduisant l'électricité, la petite extrémité de celui-ci étant appliquée contre la cuvette en zinc 66 de la pile inférieure B, et sa grande extrémité reposant sur le rebord 108.

   Le ressort est terminé par un doigt rentrant 128, qui lorsque le couvercle de fermeture est vissé sur le bas du bottier de la torche, est pressé contre le bord intérieur du bas du bottier de manière à établir un bon contact électrique avec un élément du dispositif électrique se trouvant à cet endroit,et qui sera décrit maintenant. 



   Le dispositif électrique. - 
Le bas du bottier 20 est tapissé par une bague 130 en matière é- lectriquement conductrice, qui est retenue par un oeillet 132. Le bord infé- rieur de la bague est rabattu sur le bord inférieur du bottier, de manière à être en bon contact avec le doigt 128 du ressort. La bague 130 est reliée à l'interrupteur électrique 18 par une lamelle allongée, électriquement con- ductrice, 134 dont le bout inférieur est connecté à la bague et attaché au bottier par l'oeillet 132 précité. Cette lamelle est logée dans la partie inférieure, plus large, de la rainure 38. Cette lamelle est, en outre, fixée par un rivet 136, isolé de la lamelle par une rondelle non conductrice 138. 



  Des rivets   140,     142   aident à la fixation de la lamelle au bottier et inter- viennent aussi dans le fonctionnement de l'interrupteur 18. Celui-ci est du type à trois positions; il convient particulièrement bien dans un bottier de torche en matière isolante. L'interrupteur est monté de façon à établir et interrompre un circuit électrique entre la lamelle conductrice 134 et une autre lamelle conductrice 144, logée dans la partie supérieure, plus étroite, de la rainure 38. 



   La lamelle 144 est fixée au bottier et connectée à l'interrup- teur par un rivet 145. Cette lamelle passe par l'ouverture 40 dans la cloi- son semi-cylindrique   34,   au-delà de la rainure 38 et dans l'encoche   46.   La lamelle 144 est aussi pourvue d'un doigt 146 parallèle à l'axe longitudinal de la tête 22 et dirigé vers la bague couvercle 70. Le bout du doigt peut venir toucher la surface arrière du réflecteur 82 près du rebord 80, et quand il est en contact,le doigt s'arc-boute entre le réflecteur et la pa- roi intérieure 46a de l'encoche 46, autour du congé 48, cet arc-boutement servant à immobiliser le doigt 146 et à établir un bon contact électrique entre celui-ci et le réflecteur.

   La partie décrite du dispositif électrique constitue une branche du circuit électrique reliant les piles B à l'ampoule électrique, le courant passant, dans cette branche, de la cuvette de zinc 66, par le ressort 126, la bague 130, la lamelle 134, l'interrupteur 18 (quand il est fermé), la lamelle 144, le réflecteur 82, le manchon 86, et le rebord 90 du socket, à l'ampoule.

   Le contact central 98 de la lampe est connecté à l'électrode de carbone à extrémité métallisée   68,  par une lamelle de contact   148   en ma- tière élastique et électriquement conductrice, comme du bronze phosphoreux, dont la partie inférieure 150 est appliquée sur un plat 152 dans le fond de la cloison semi-circulaire 34. Cette partie inférieure se raccorde par un pli incurvé 153 à la partie 154 de la lamelle servant au contact et incli- née vers l'avant de manière à venir s'appliquer contre le contact central 98 de l'ampoule. Détendue, la lamelle de contact 154 prend la position in- diquée sur la figure   6;,   tandis qu'elle prend la position indiquée à la fi- gure 3,quand la tête est montée. 



   La base 150 de la lamelle est fixée sur la cloison 34 par un oeillet 156 en matière électriquement conductrice dont l'extrémité inférieure est repoussée sur une rondelle électriquement conductrice 158 posée sur un plat 159 sur la face inférieure de la cloison 34, la rondelle et la base 150 servant à répartir l'effort imposé à la cloison 34, quand l'oeillet 156 est rivé. 



     L'électrode   de carbone à extrémité métallisée 68 est appliquée contre la face inférieure de l'oeillet 156 par le ressort de compression des piles   126  de manière à fermer le circuit de l'électrode de carbone vers le contact central de l'ampoule,par l'intermédiaire de l'oeillet et du res- sort de contact 148 
La description ci-dessus montre que la torche décrite,répond aux différents buts de l'invention et convient très bien à être utilisée en pra- tique . 



   D'autres formes   dexécution   de   l'invention   peuvent être réalisées et des modifications peuvent être apportées à la forme d'exécution représentée et décrite ci-dessusqui n'est donnée qu'à titre   d'exemple,   sans que l'in- vention y soit limitée.

  ELECTRIC TORCH.



   The present invention relates to electric torches, and especially to those with a square head.



   The object of the invention is to provide a torch of this type having a plastic housing constructed so as to be undeformable and unbreakable under severe conditions of use such as extreme cold and extreme dry or humid heat.



   Another object of the invention is to provide a torch of the type mentioned, made up of a small number of simple parts, and showing itself to be very efficient in use.
Other objects of the invention will become apparent from the following description or will be indicated hereinafter.



   The invention consists of the construction features, combinations of elements, and arrangements of parts described below.



   One of the various possible embodiments of the invention is shown in the accompanying drawings, in which,
Figure 1 is a side view of a torch according to the invention
Figure 2 is a longitudinal section taken on line 2-2 of Figure 1.



   Figure 3 is a longitudinal section taken along line 3-3 of Figure 20
Figures 4 and 5 are sections taken substantially along lines 4-4 and 5-5 of Figure 3 respectively, showing details one of the head and the other of the base of the torch.



   FIG. 6 represents, in section, the torch dismantled from before to

 <Desc / Clms Page number 2>

   1-1 rear.



   Figures 7 and 8 are sections taken substantially along lines 7-7 and 8-8 of Figure 6, respectively.



   As the drawing shows, the angled head torch 10 of the invention is generally composed of a battery pack 12, a head 14, a bottom 16 and an electrical device comprising a switch 18. and various head and bottom elements.



   Stacker.
The housing 12 made of a moldable insulating material such as, for example, a phenolic condensation product or cellulose acetate butyrate, is composed of a body 20 and a head 22 made in one piece.



  The body consists of a hollow cylindrical tube with an open bottom provided with a screw thread 23 onto which the bottom is screwed. The body is provided, immediately above the thread, with a circumferential bead 24 for consolidation. A similar bead 26 is provided at the upper body for the sake of symmetry. Between these two beads, the outer surface of the casing is provided with several longitudinal molded ribs 28 serving to make the casing more rigid and thus give it great strength, while keeping its walls as thin as possible, for the sake of lightening the torch and manufacturing economy.



   The head 22 of the housing comprises a cylindrical tube having the diameter of the body 20 and made integrally therewith, the junction surfaces of the head and the body being rounded at the rear of the head, at 30. .



   The front of the cylindrical tube constituting the head 22 is provided with a screw thread 32 serving to assemble the head 14.



   Although located inside the housing 12 of the torch, the lower wall 34 of the tube constituting the head 22 is left substantially intact (FIG. 2) and it connects one side of the housing 20 of the housing to the diametrically opposite side. This lower wall 34 constitutes a curved partition, concave upwards, separating the head from the body and appreciably reinforcing the impact resistance of the casing, also making it less deformable at high temperatures and in humid or dry atmospheric conditions. ches.



   The interior of the housing 12 has a special configuration to adapt to the different parts of the electrical device without the strength or robustness of the housing being seriously affected.



   The inner wall of the body of the casemaker has two spaced parallel ribs 36 which define between them a groove 38 which becomes a little narrower in the upper part of the body 20. It will be noted that the ribs pass along and under the switch 18. , thus reinforcing the box where it is drilled and emptied to allow assembly of the switch.



   The upper end of the groove 38 passes through an opening 40 made in the semi-cylindrical partition 34 forming part of the head.



  Immediately above this opening and above the end of the groove 38, is a slightly tapered lug 42 integral with the casing. This lug is parallel to the longitudinal axis of the head 22 and is connected to the latter by a rib 44 which stops a little before the end of the lug, so as to constitute a notch 46 whose walls are spaced radially from the longitudinal axis of the head and face towards the front thereof. The front of the head, bearing the molded screw thread 32, has a larger internal diameter than that of the rear of the head which is one with the body 20 of the casemaker.



   The flared front part of the head is connected to the rear part by a fillet 48 The top of the fillet interposes a fixed obstacle between the inner wall 46a of the notch 46 and the inner wall 47 of the front part of the head 22. The reason for this construction will be given by studying

 <Desc / Clms Page number 3>

 the electrical device.



   To facilitate the molding of the case in one piece, the reinforcing semi-cylindrical partition 34 may be pierced with an additional opening 50 in which the molding cores of the body and the head meet. As indicated, this opening 50 may be at the rear of the head. The partition is reinforced, at the height of this opening, by a vertical rib 52 which extends from one side to the other of the semi-cylindrical partition 34. To further strengthen the semi-cylindrical partition and all the shoemaker in general, this rib is associated, in a manner described below, with an element of the electrical device.



   It is preferable to reinforce the ends of the rib as well and this is done by molding a pair of clips 54 between the rib and neighboring parts of the head and body. These fasteners prevent bending or deforming the rib 52 forward or backward.



   To facilitate the carrying of the torch, the shoemaker is provided with an ordinary elastic metal hook 56, attached to the shoemaker by means of two rivets 58 which pass through holes in the hook and in the back ¯ of the shoemaker and whose inner ends are riveted on a steel strip 60 inside the casing. It will be noted that the casing is notably reinforced at this point to better resist the deforming forces, on the outside by a large buttress 28 and on the inside by a flat 62.



   Finally, the casing also has several holes and recesses, which will be described below to house and hold various elements of the electrical device.



   The housing contains the usual set of B batteries, slipped into a bottomless fibrous sleeve 64, so that the batteries are connected in series and the zinc cup 66 of the lower battery is accessible at the bottom of the sleeve, while the The carbon electrode, metallized at the end, 68 of the upper stack is accessible at the top of the sleeve.



   The head. -
The head comprises a lens ring 70 made of plastic material with internal threads 72 matching the threads 32 of the front part of the head 22.The front edge of the lens ring has a re-entrant flange 74 which constitutes a base 76 against which the lens 78 is applied.



  This lens can be made of any transparent material, such as glass or a transparent plastic material, for example methyl methacrylate, a vinyl ester resin, a vinyl acetal resin or cellulose acetate butyrate. The lens may be in the form of a circular flat disc, as shown, since it is associated with a parabolic reflector, the word "lens" being commonly used without any of its faces being curved. towards the outside 80 of an electrically conductive parabolic reflector 82 is caught between the rear face of the lens and the front edge of the head 22, therefore behind the lens.

   The reflector is mounted so as to constitute, with an electric bulb 84, a prefocused assembly, the reflector serving to pass the current from one pole of the battery B to the lighting bulb. For this purpose a threaded sleeve 86 made of an electrically conductive material may be riveted to the rear end of the reflector, the front of the sleeve being riveted by an inward fold, constituting a stop 88 against which the sleeve is riveted. front of the rim 90 in the base of the electric bulb 84 comes to rest, The base is pushed against the stop by a plug 92 made of the same insulating material as the housing 12. This plug is threaded and is screwed into the sleeve 86; to facilitate the rotation of the cap, the latter is provided at the rear, on its contour 959, with grooves 94.

   The plug is pierced right through with a large opening 96 in which the base of the light bulb fits freely, the central contact 98 of the base protruding from the rear 95 of the plug, so as to easily come into contact with a bulb. part of the electrical device.

  The bottom. -
The bottom comprises a closing cover 100 made of the same plastic material as the casing 12. The cover is closed below by a bottom 102, while its upper part, open, is provided with a thread 104 which adapts to the thread 23 of the lower body 20 of the casing. The thread 104 is separated from the bottom 102 by a space large enough to be able to accommodate therein the major part of a reserve bulb 106 placed across the closure cover, the wall of the cover which surrounds this space becoming thicker. so as to constitute a rim 108 on which rests the fitting 110 which carries the reserve bulb. This fitting, made of a single metal strip, consists of a flange 112, the two ends of which 114 are rounded so as to match the inner wall of the cover above the rim 108.



  The central part 116 of the flange is raised and split axially at 118, to receive a part of the rim 120 of the socket of the spare bulb 106. The latter is held by two elastic fingers 122 cut in the flange and formed in a manner. to tighten socket 124 of the reserve bulb. The bracket carrying the spare bulb is pressed against the flange 108 by a conical helical stack compression spring 126, made of an electrically conductive material, the small end thereof being pressed against the cup in zinc 66 from lower pile B, and its large end resting on ledge 108.

   The spring is terminated by a retractable finger 128, which when the closing cover is screwed onto the bottom of the torch housing, is pressed against the inner edge of the bottom of the housing so as to establish good electrical contact with an element of the device. electric located at this location, and which will now be described.



   The electrical device. -
The bottom of the casing 20 is lined with a ring 130 of electrically conductive material, which is retained by an eyelet 132. The lower edge of the ring is folded over the lower edge of the casing, so as to be in good contact. with finger 128 of the spring. The ring 130 is connected to the electrical switch 18 by an elongated, electrically conductive strip 134, the lower end of which is connected to the ring and attached to the casing by the aforementioned eyelet 132. This strip is housed in the lower, wider part of the groove 38. This strip is also fixed by a rivet 136, isolated from the strip by a non-conductive washer 138.



  Rivets 140, 142 help in fixing the strip to the casing and also intervene in the operation of switch 18. This is of the three-position type; it is particularly suitable in a torch housing made of insulating material. The switch is mounted so as to establish and interrupt an electrical circuit between the conductive blade 134 and another conductive blade 144, housed in the upper, narrower part of the groove 38.



   The strip 144 is fixed to the housing and connected to the switch by a rivet 145. This strip passes through the opening 40 in the semi-cylindrical wall 34, beyond the groove 38 and into the notch. 46.
