In practice, these training devices 1) i-6.seiiterit Lin large iiieoliv4iiient, because for the eainhas taking pictures, the loading is often done in a dark room. <B>11</B> is then sometimes difficult to get the protrusion of the inotor fax into one of the Wian-errors of the reel.

Wautre part, pour faeiliter la niise en 1)laee de la bobine stir son axe, on laisse n#ces- sairement subsister entre les deux pPees un eertain jeLi qui, lors de Fentrainenient, est une souree de brait. On the other hand, to facilitate the laying in 1) laee of the coil on its axis, one leaves necessarily to remain between the two pPees a certain jeLi which, during the training, is a source of brait.

La pi,6sente invention a pour objet d'gli- miner ]es ineonv#nients prgeit6s. Elle eon- (lerne tin dispositif de fixation (Vune bobine de film sLir un axe, porir eairigi-a de prise de vues et appareil de projeetion ein6mato,-ra- phique, eomprenant une douille montge sur Faxe stir lequel. est destijA <B>ä,</B> Ure plack la bobine, ladite douille & ant munie sur une partie de sa longueur dorganes faisant 61asti- quement saillie radialement, le diamkre du eerele eirconserit aux saillies Atant plus grand que le trou de la bobine, de sorte qLie celle-ei est maintenue sur la douille au moins par ser- rage Mastique. The object of the pi,6sente invention is to eliminate the inconveniences foreseen. It consists of a fixing device (a reel of film on an axis, a film camera and an ein6mato graphic projection device, comprising a socket mounted on a machine on which it is intended. >ä,</B> Plack the coil, said sleeve & ant provided over a part of its length with organs projecting 61astically radially, the diameter of the eerele eirconserit at the projections Atant larger than the hole of the coil, so qLie this is held on the bushing at least by Mastic tightening.

Ce dispositif de fixation est earaet#ris# par le fait qLiau nioins Fun des organes 61as- tiques est de dimension telle qu'il puisse pin & trer dans une gehanerLire du trou de la bo- bine, cet organe 61astique, Atant suseeptible d'At,re rapproeh4 61astiquement de Faxe autant que le diamkre du cerele inserit dans le RTI ID="0001.0275" WI="7" HE="3" LX="1725" LY="1445"> trou de la bobine l'exige, de telle sorte que la bo- bine paisse, ainsi ftre engag6e sur Faxe dans Wimporte quelle position angulaire par rap- port <B>A</B> eelui-ei. This fixing device is earaet#ris# by the fact that at least one of the 61astic organs is of such a size that it can pinch in a gehanerLire of the hole of the coil, this 61astic organ, Atant likely to At,re approximates4 61astically as far as the diameter of the ring inserted in the RTI ID="0001.0275" WI="7" HE="3" LX="1725" LY="1445"> coil hole requires , so that the coil thickens, thus being engaged on Faxe in any angular position with respect to <B>A</B> itself.

Le dessin annexe represente, seMmatique- inent et<B>ä</B> titre d'exemple, une forme d'exku- tion de Pobjet de Pinvention. The accompanying drawing represents, schematically and <B>ä</B> by way of example, one embodiment of the object of the invention.

La fig. <B>1-</B> est une 616vation dun axe m.o- teur avee, parties en eoupe, pour bobine rgeep- trice. fig. <B>1-</B> is a 616 elevation of a motor shaft with cross-sections for a recoil.

La Tig. 2 en est une vue en plan. The Tig. 2 is a plan view.

La fig. <B>ö</B> est une AMvation, avee parties en eoupe, dune bobine d6bitrice niont6e sur un axe-support. fig. <B>ö</B> is an extension, with split parts, of a delivery reel mounted on a support shaft.

La fig-. 4 est une eoupe, selon la ligne 1V-IV de la fig. <B>3.</B> Fig-. 4 is a eoupe, along the line IV-IV of FIG. <B>3.</B>

En r#grence <B>ä</B> la fig. <B>1</B> du dessin, on voit une platine <B>1</B> qui supporte un axe moteur 2,, eoniiiiand6 par un pigrion <B>3,</B> par Finterme- diaire d'un dispositif <B>ä</B> frietion 4. Une douille <B>5,</B> de forme -6n#rale eyjindriqui.e, est ii.x#e sur Faxe 2 et comporte, <B>ä</B> partir de son extr6mit# ini6rieLire, des fentes longitudinales <B>6</B> for- mant quatre languettes <B>7</B> et<B>8.</B> L'extr#mit# .supC-rieLire de Faxe porte un ehapeau <B>9 A.</B> sur- faee bomb6e en vue de faeiliter la mise en place de la bobine. La partie de la douille portant les langLtettes est constit-LiAe de ma- nkre <B>ä</B> prgsenter une forme conique, e'est- ä-dire que le diamUre du cerele eireonserit <B>ä</B> la base de la douille <B>5</B> est plus grand quie eelui de soli extrgmit,6 sup6rieure. Ce dernier est ehoisi plus petit que le trou eentral de la bo- bine, tandis que le diamUre de la base est plus grand que eelui de ee trou eentral. With reference <B>ä</B> to fig. <B>1</B> of the drawing, we see a plate <B>1</B> which supports a motor shaft 2,, eoniiiiand6 by a pinion <B>3,</B> by the intermediary of a device <B>ä</B> frietion 4. A socket <B>5,</B> of -6n#rale eyjindriqui.e shape, is ii.x#e on Faxe 2 and comprises, <B>ä </B> from its inner end, longitudinal slits <B>6</B> forming four tabs <B>7</B> and <B>8.</B> The end # .supC-rieLire de Faxe wears a <B>9 A.</B> curved surfacing to facilitate the positioning of the coil. The part of the sleeve bearing the tabs is made so as to <B>ä</B> present a conical shape, that is to say that the diameter of the ring is <B>ä</B> the base of socket <B>5</B> is larger than that of the upper end. The latter is chosen smaller than the central hole of the coil, while the diameter of the base is larger than that of the central hole.

L une, <B>8,</B> des quatre languettes de la douille <B>5</B> est eonstitu4e de manAre <B>ä</B> faire saillie en dehors du eerele eirconserit aux trois autres, <B>7,</B> et sa, largeur est choisie de inani#re <B>ä</B> eorres- pondre <B>ä</B> celle d'une des 6chanci-Lires <B>10</B> du trou de la bobine. One, <B>8,</B> of the four tabs of the sleeve <B>5</B> is made so as to <B>ä</B> protrude outside the circle of the other three, < B>7,</B> and its width is chosen so that <B>ä</B> corresponds <B>ä</B> to that of one of the 6chanci-Lires <B>10< /B> of the coil hole.

La fig. <B>3</B> reprgsente une bobine d#bitriee niontie sur -tin axe 2' qui est un axe-support riv6 sur la platine <B>1.</B> Dans ee eas, la douille <B>5</B> est montAe folle sur Faxe 2' et est entraine'e librement par la bobine dgbitriee qui com- porte, comme la bobine rekeptrice non repr6- sentge, un noyaLt <B>11</B> et deux joues <B>1-.</B> Autour des ouvertures eentrales des joues 12, pr#vues au eentre du noyau, sont dispos6es quatre #ehanerures <B>10.</B> fig. <B>3</B> represents a bitrated coil mounted on -tin shaft 2' which is a support shaft riveted to plate <B>1.</B> In this case, socket <B>5 </B> is mounted loose on Faxe 2' and is driven freely by the debit coil which comprises, like the take-up coil not shown, a core <B>11</B> and two flanges <B >1-.</B> Around the central openings of the flanges 12, provided at the center of the core, are arranged four #ehanerures <B>10.</B>

Le fonetionnement de ee dispositif est le stlivant: La bobine est introduite dans n'importe quelle position sur la douille <B>5.</B> Elle deseend. sans rgsistance jusqa'au moment oü le dia- mkre de son trou eentral eorrespond <B>ä</B> un des diamkres du trone de cöne. <B>A</B> ee moment, une lAg#re pression sur la bobine la foree sur ].es lamelles <B>7</B> et<B>8></B> ee qLii a pour effet de faire flAchir eelles-ei contre le centre. La bobine est en plaee au moment oü elle bute contre la rondelle <B>13.</B> The operation of this device is as follows: The coil is inserted in any position on socket <B>5.</B> It drops. without resistance until the diameter of its central hole corresponds <B>ä</B> to one of the diameters of the throne of the cone. <B>A</B> At this moment, a slight pressure on the reel forces it on the slats <B>7</B> and <B>8></B> ee qLii has the effect of flAck them-ei against the center. The spool is in place when it hits the puck <B>13.</B>

La pression des lanielles stir la bobine pro- voque, dans le eas de la fig. <B>1,</B> tine frietion permettant la transinission du mouvement, de rotation <B>4</B> la bobine receptriee et, dans le eas de la fig. <B>3,</B> un entrainentent de la douille ;5 par la bobine d#bitriee, RTI ID="0002.0278" WI="3" HE="3" LX="1527" LY="256"> la rotation des bo- bines se faisant ainsi sails jeu et salis bruit. Dans le eas de la fig. <B>1,</B> si eette frietion est trop faible pour entrainer la bobine r6eep- triee, la lanielle <B>8</B> fera offiee de s#eiirit6. En effet, si on admet qLie la lamelle <B>8,</B> lors de Pintrodaetion de la bobine sur son axe, ne se trouve pas engaggAe dans Fune des 6ehanei-Lires <B>10</B> de la bobine, la douille <B>5</B> tourne sans en- trainer la bobine, la frietion kant trop iaible entre elle et eelle-ei. L'entrainement se fera au moment oü la lanielle <B>8</B> sera ventie, ---rz^tee <B>ü.</B> son 6lastieith, se loger dans Fune des #ehan- erures <B>10.</B> La liaison entre doaille et bobine est alors rigide. La bobine r6eeptriee peut done Ure introduite dans Wimporte quielle position sur son axe, elle sera to-ajours en- traink. The pressure of the strips on the coil causes, in the case of FIG. <B>1,</B> tine frietion allowing the transmission of the movement, of rotation <B>4</B> the received coil and, in the case of fig. <B>3,</B> a lead from socket ;5 through the bit coil, RTI ID="0002.0278" WI="3" HE="3" LX="1527" LY="256"> the rotation of the spools thus making itself loose and dirty noise. In the case of fig. <B>1,</B> if this friction is too low to drive the re-ejected coil, the strip <B>8</B> will act as a safety device. Indeed, if we admit that the strip <B>8,</B> during the introduction of the coil on its axis, is not engaged in one of the 6ehanei-Lires <B>10</B> of the coil , socket <B>5</B> rotates without driving the coil, the friction between it and eelle-ei is too low. The training will be done when the strap <B>8</B> is ventie, ---rz^tee <B>ü.</B> its 6lastieith, lodge in one of the #ehan- erures <B >10.</B> The connection between needle and coil is then rigid. The received coil can therefore be introduced in any position on its axis, it will always be driven.

Cette douille #lastique <B>5</B> permet en nikie temps de supprinier le seeond ineoli-v6nient" e.'est-ä-dire le bruit. La pression kastique des länielles sur la bobine supprinie le jeu entre elle et son axe, et en Mime tenips le bruit pen- dant, la marehe. This #elastic sleeve <B>5</B> allows in no time to suppress the second ineoli-v6nient" i.e. the noise. The kastic pressure of the läniels on the coil suppresses the play between it and its axis, and in Mime keep the noise during the march.

Le noliibre des lamelles 61asticiiies de la douille <B>5</B> peut kre difMrent de eelui i-epp#- sent,6 au dessin. The number of the plasticized strips of the sleeve <B>5</B> may be different from that shown in the drawing.

La bobine r & eptriee pourrait btre entrai- nee uniqueinent par frottenient, sans pr#voir de lainelle <B>8.</B> The re-ejected coil could be driven only by friction, without providing for <B>8 wool.</B>

Les organes kastiques de la douille pour- raient kre constitugs par des lamelles rivges ou fixAes Tune aatre manik-e sar sa partie siip#rieure. Ils pourraient aussi kre eonsti- tii6s par des lames pivot#es et soumises <B>ä</B> Fae- tion des ressorts. The kastic organs of the socket could be made up of lamellae riveted or fixed in a separate manner on its upper part. They could also be constituted by blades pivoted and subjected <B>ä</B> to the action of the springs.

En variante eneore, les lamelles, au lieu d'aller simplement en s'6vasant vers leur extr6- mit6 libre, poLtrraiellt en plus Ure tordues de fa#on que dans Lin plan perpendieulaire <B>ä</B> Faxe moteur, elles pr#sentent une disposition en forme g6n6rale de dents de lo-Lip. De pr & Mrenee, elia(1-Lie laiiielle irait en s'geartant de Faxe 2 dans le sens d'entrainement de eellii-ei. Une telle disposition des lamelles faeiliterait leur engagement dans les 6ehanertires <B>10.</B> As a further variant, the slats, instead of simply splaying out towards their free end, may additionally be twisted so that in the perpendicular plane <B>ä</B> of the engine, they present a disposition in the general form of lo-Lip teeth. From pr & Mrenee, elia(1-Lie laiiielle would move away from Faxe 2 in the driving direction of eellii-ei. Such an arrangement of the slats would facilitate their engagement in the 6ehanertires <B>10.</B>
