Ces fiches sont prolongees @ä Vin terieur :de la calotte par .des tiges filetees 6 respectivement 7, sur lesquelles se vissent des kraus 8 destines ä serrer rigidement les fiches dans la calotte, avec interposition de rondelles isolantes 9. cap by insulating washers 5; On these plugs, place the power outlet, not shown, rediant the iron to the source of electricity. These plugs are extended inside the cap by threaded rods 6 respectively 7, on which are screwed kraus 8 intended to rigidly tighten the plugs in the cap, with the interposition of insulating washers 9.

Sur 1a tige filetee 7 sont montes un bras 10 qui presente !ä son egtremite un trau filete 11 et un bras 13 qui Porte ä, son egtremit & , dune pari, une pike 14, d'autre Part, une lame elastique 15, la pike 14 et la lame 15 etant rivees sur 1e bras 1:3. La pike 14 Porte ä son @extremite, recourbee :ä angle droit, une vis 16, tandis.,que la lame 15 est pourvue ä son egtremitü libre 17 @d'un contact 1,8, rive sur edle. La bras 1.3 est isol6 du bras 10 par des rondelles@ isolantes 19 et :de la tige 7 par un canon isolant non figure. Le taut est for tement serre ensemble et eur fkrou 8 par un e.crou 20, avee interposition @de rnndelles isolantes 2'1, On the threaded rod 7 are mounted an arm 10 which has its end a threaded trau 11 and an arm 13 which carries its end &, a bet, a pike 14, on the other hand, an elastic blade 15, the pike 14 and blade 15 being riveted to the 1:3 arm. The pike 14 carries at its extremity, curved: at right angles, a screw 16, while the blade 15 is provided at its free end 17 with a contact 1.8, edge on edge. The arm 1 .3 is isolated from the arm 10 by insulating washers 19 and: from the rod 7 by an insulating sleeve not shown. The taut is strongly tightened together and eur fkrou 8 by a nut 20, with interposition @ of rnndelles insulating 2'1,

Sur la calotte 2, entre 1e bord arriere de celle-ei et les fiehes 3 et 4, est fixee rigide ment par Fune de ses extremites une laure bi-metallique 22 disposee de ma"niere qu'en s'incurvant sous Finfluence de la temp@ra ture, sa concavite soit tournee verä la ca lotte 2. A 1'extremite libre de cette laure est vissee une tige filet@e 23, dont un ecrou de serrage 24 fixe la position dann la. laure 22; cette tige 23 penetre ä, 1'interieur de la. ca" lohe par une ouverture 2.5 de oelle-ei; la long-aeur de la tige,est telle que son extremite pourvue d'un capuchon isolant 26 soit rap proch@e de la laure 15 lorsque la laine bi metallique `?? est froide. On the cap 2, between the rear edge of the latter and the fiehes 3 and 4, is fixed rigidly by one of its ends a bi-metallic laurel 22 arranged in such a way that by curving under the influence of the temperature, its concavity is turned towards the cap 2. A the free end of this laure is screwed on a threaded rod 23, of which a clamping nut 24 fixes the position in the laure 22. this rod 23 penetrates to the interior of the. ca"lohe through an opening 2.5 of oelle-ei; the long-aeur of the rod, is such that its end provided with an insulating cap 26 is rap proch @ e of the laurel 15 when the bi-metallic wool `?? is cold.

La. calotte 2 presente encore une ouver ture 27 au travers de laquelle passe une tige 28 dont une extremite filetee se visse dans 1e trou 11. du bra.s 10; Bette extremite poste un contact 29 sur lequel v ient norinalement s'ap puyer 1e contaet 18 poste par la lame Masti que 15. Lautre extremite de 1a. tige 28 poste, exterieurement ä la ealotte ?, un bouton iso lant mollete 30 pourvu d'un repere et de signes -f-- -et -. La tige 28 est reeouverte Tune gaine isolante 31 s'etendaut sur toute sa longueur entre 1e bouton mollet@ et son extremite filetee. La longueur de Ia partie filetee de la tige 28 est plus grande que Fepaisseur du bras 10. La. cap 2 still has an opening 27 through which passes a rod 28 whose threaded end is screwed into the first hole 11 of the bra.s 10; Bette extremity posts a contact 29 on which normally comes to rest the first contact and 18 posts by the Masti blade 15. The other extremity of 1a. rod 28 post, outside the shell?, an insulating knob 30 provided with a mark and signs -f-- -and -. The rod 28 is reeouverte Tune insulating sheath 31 extends over its entire length between the first button calf @ and its threaded end. The length of the threaded portion of rod 28 is greater than the thickness of arm 10.

La bras 10 est dispoce de telle maniere que Faxe de 1a tige 28 e-t, par consequent, du conta"0t 29. soit excentre par rapport h. celui du contact 18; en outre, 1e contaet 29 a un diametre sensiblement plus grand que 1e contact 18. Il resulte de cette disposition que par la. manoeuvre du bouton 30. 1e contact 29 se deplace, non seulement axialement mais a.ussi lateralement par rapport au contact 18. The arm 10 is arranged in such a way that the axis of the rod 28 is, consequently, of the contact 29. is eccentric with respect to that of the contact 18; moreover, the first contact 29 has a diameter substantially larger than the first contact 18. It results from this arrangement that by the operation of the button 30, the first contact 29 moves, not only axially but also laterally with respect to the contact 18.

Le fouctionnement du fer represent@ est 1e siiivant: Le fer ä. repasser kant connecte ä la source d'electricit6. 1e courant passe, par exemple. de 1a tige 3 au Corps cle chauffe 1a, puis ä, la vis 16, la pike 14, la laure 15 et au contact 18; 1e fer etant froid, la laure bi meta"llique est encore dans sa position de re pos et hent 1e capuchon 26 eloignA de la laure The operation of the iron represented is as follows: The iron ä. iron kant connected to the power source. 1st current passes, for example. from the rod 3 to the heating body 1a, then to the screw 16, the pike 14, the blade 15 and to the contact 18; the first iron being cold, the bi-metallic laurel is still in its rest position and holds the cap 26 away from the laurel

15; 1e contact 18 appuie donc sur 1e contaet 29 et 1e eourant passe de co contaet ä, la tige 28, puis au bras 10 et de Ih a la fiche 4 pour retourner au reseau. 15; 1st contact 18 therefore presses on 1st contact 29 and the 1st current passes from co contact to rod 28, then to arm 10 and from Ih to plug 4 to return to the network.

La fer ä. repasser s'khauffant, la. laure bi inetallique s'incurve Bot rapproche 1e eapu chon 26 de, la, laure 15 ,jusqu'au moment oit la temperature du fer ayant atteint une cer faine valeur, le capuehon appuie sur la laure l) t-t rompt 1e contact entre 18 et 29; 1e courant est coupe et 1e fer conimence ä. se re froidir: en se reafroidissant. la laure 22 se re dresse et ce inouvement pennet au eontact 18 de se rapproche:r du contact 29 jusqu'i, venir en conta.0t avec lui: le fer s'eehauffe 2 nou veau. 1a, laine 22 s'incurve. le capuchon 26 appuie siir 1a laure 15 et separe 18 de 2D et ainsi de suite. La temperature du fer sera donc autoinatiquement maintenue entre deux valeurs definissant 1'insensibilito du re'glage. Iron ä. iron warming up, the. laure bi inetallique bends Bot brings the eapu chon 26 closer to, la, laure 15, until the moment when the temperature of the iron having reached a certain value, the capehon presses on the laure l) t-t breaks the contact between 18 and 29; the current is interrupted and the iron starts at. to cool down: by cooling down. lavra 22 stands up and this innovation allows contact 18 to approach contact 29 until it comes into contact with it: the iron heats up 2 again. 1a, wool 22 curls. cap 26 presses siir 1a laure 15 and separates 18 from 2D and so on. The temperature of the iron will therefore be automatically maintained between two values defining the insensitivity of the adjustment.

L n ajustage de 1a, valeur de 1a. temp@ra ture regle < peut etre obtenu en ma"noeuv ra.nt 1e bouton 30. en tournaut celui-ei dans 1e sens "-i-", an visse la, tige 28 dann 1e bras 10 et 1e contact 29 appuyant sur 1e contact 18 eloigne la laure 15 du oapuehon 26; il faudra done que la laure 22 s'incurve davan tage pour atteindre la Iame 15 et 1e courant ne Sera coupe que pour une temperature du fer plus elevee. Le resultat inverse est obtenu en manoeuvrant 1e bouton dans 1e sens "-". La position excentreo des axes des deux con taets presente l'avantage que 1e depla"oement du eoniaet 29 a pour effet de froher les contacts 1'un contre Fautre et de les nettoyer. L n adjustment of 1a, value of 1a. regulated temp@ra ture < can be obtained by my new ra.nt the 1st button 30. by turning it in the 1st direction "-i-", an screw it, rod 28 in the 1st arm 10 and the 1st contact 29 pressing on the contact 18 distances the lavra 15 from the oapuehon 26. it will therefore be necessary for the lavra 22 to curve further to reach the blade 15 and the current will only be cut for a higher temperature of the iron. The opposite result is obtained by maneuvering the 1st button in the 1st "-" direction The eccentric position of the axes of the two contacts has the advantage that the first movement of the cone 29 has the effect of rubbing the contacts against each other and cleaning them.

La laure bi-metallique 22 pourrait eire montee ä. 1'intkrieur de la calotte au lieu de 1'exterieur. The bi-metallic lavra 22 could be mounted at. inside the shell instead of outside.

L'ajustage du point de reglage de la Iiem p6rature pourrait se faire aussi en agissant sur la tige 23 au moyen d'un bouton exte rieur monte sur rette tige et uruni de reperes; en rapprochant plus ou moins 1e capuchon 26 de la laure 1,5, an modifie la temperature pour laquelle 1e capuchon 26 entre en eon taet avee rette laure 15. The adjustment of the adjustment point of the Iiem p6rature could also be done by acting on the rod 23 by means of an external button mounted on this rod and provided with marks; by bringing the cap 26 closer or less to the laure 1.5, an modifies the temperature for which the first cap 26 enters into eon taet with rette laure 15.

La disposition ei-dessus dkrite permet d'utiliser des Corps de ehauffe d'un type The provision described above allows the use of heating bodies of a type

normal, malgre la presence @du regulateur :de temperature. normal, despite the presence @of the temperature regulator.
