PHOTOGRAPHING AND DEVELOPING APPARATUS.

Application filed June 11, 1914.

To all whom it may concern:

Be it known that I. GEORGE C. BEIDLER, a citizen of the United States of America, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Photographing and Developing Apparatus, of which the following is a specification.

This invention relates to photographing and developing apparatus and particularly to that type of apparatus embodying means for exposing film to light, severing the portion of the film exposed after it is mechanically drawn from the means for exposing it to light, the cutting of the exposed portion of the film from the remainder of the film web, and means for developing the section of the film exposed.

An object of the present invention is to provide means for delivering an exposed section of film to a receptacle which may contain fluid adapted to act on the coated surface of the film, such as developing solution, and novel means for drawing the fil'm from the said receptacle and for severing the same; the invention furthermore consisting in means for subjecting the developed film to the action of a fluid contained in another receptacle to which the film is delivered after it is removed from the first receptacle, novel means being provided for submerging the film therein to insure proper contact of the liquid with the said film and for other purposes, all of which mechanism is preferably contained within a light-proof casing, capable of excluding actinic rays of light, during the time the mechanism is operating for treating the film.

A further object of this invention is to provide novel means for subjecting film to the action of fluid. the provision of means for submerging the film, the provision of means for cutting the film, said means being correlated and associated to effect the development of an exposed film mechanically while the said film is guarded from light.

\Vith the foregoing and other objects in view, the invention consists in the broad idea to be set forth in the claims during the prosecution of the application, the said claims to be of such scope as to give protection commensurate with the inventive act in view of the state of the art when the said-invention was produced.

In describing the invention in detail, reference will be had to the accompanying Specification of Letters Patent.

In these drawings, I have shown an inclosure divided into several compartments but the manner of forming the compart ments is not material and may be changed to suit particular requirements. In the present embodiment of the invention. I have shown a magazine section 20 and a receptacle casing 21, the latter of which is provided with a door 22, hinged at 23, so that access to the interior of the receptacle casing may be facilitated and the said receptacle casing may be further provided with a hinged end 24.

The receptacle casing is shown as having longitudinally disposed partitions 25 near the sides thereof, the said partitions forming compartments 26 adapted to contain operating mechanism which is preferably constructed of metal so that the said partitions act as shields for these metal parts and protect them against chemicals which grief! used in the development or fixing of the The inner surface of each side of the receptacle casing has a substantially F-shaped guide 27 secured to it and an angle bracket is furthermore secured to the guide plate producing the double guides 29 and 30 for a purpose to be presently explained. The partitions 25 have slots 31 horizontally disposed and extending longitudinally to form ways for the passage therethrough of blocks 33 and 34, slidable on the guides 30, it being observed that the said blocks have slots 34 forming clearances for the reception of the said guides. Each block is provided with a socket 35 to receive the trunnion 36 on the rod 32 so that said rod may rotate, although 1 the rotary action is not essential to its operation. The purpose of the rod is to engage and pull film from a receptacle.

As a means for moving the blocks longitudinally of the guides, each block has a socket 37 which receives a stud 38 forming a continuation of one of the link pins 39 of the chain 40, and, therefore, movement of the chain of each block, results in moving the block. The guides 30 act as supports forthe chains in their travel longitudinally of the casing.

A receptacle 41 extends through the bottom of the casing 21 and is supported or suspended by any appropriate means as by the angle irons 42 and the said receptacle is adapted to contain fluid which Wlll act on the coatedsurface of the film, after it has been exposed tolight and in most instances, the said receptacle isused as a container for developing fluid. At a point above the receptacle 41 or in such position that film may be delivered to the receptacle by their action, are film drawing rolls 43 and 44 which may be journaled in any appropriate way in the casing, one ofsaid drawing rolls, preferably the drawing roll 43 having a shaft 45 extending beyond the casing andhavlng a crank handle 46 applied to it so that the said roll may be turned and as the peripheries of the said rolls are practically in contact under normal conditions and are adapted to bear against the surface of film when they are caused to coact for the purpose of drawing the film, the said rolls operate to draw film from the magazine 20 so that said film may be delivered to the receptacle 41.

The magazine 20 has a front wall 47 .which constitutes a backing for the film,

which is drawn over the anti-friction roller 43, journaled near the top of the mechamsm, said anti-friction roller and down into the casing 21 containing the receptacle 41.

and the film is caused to travel over Thatportion of the magazine in front of the wall 47 constitutes an exposing chamber in which the film is subjected to the action.

of light which may be admitted through the bellows 49 and the bellows frame 50, which latter is fitted to the front portion of the magazine or an extension thereof. The dark slide 51 which may move transversely of the exposing chamber is of a type ordinarily employed and is movable in guides 52 and 53 formed in the structure constituting the magazine chamber or an extension thereof.

Theinteri'or of the casing 21 has a supporting means for the ends of a stationary knife 54 which knife is stationed with its cutting edge in vertical alinement or nearly so, with the contacting surface of the rolls 43 and44' so that the film fed between the rolls passes the cuttting edge of the stationary knife and is in position to be out when the movable knife 55 is carried into engage: ment or coaction with the stationary knife; Tn order to operate the movable knife it is mounted'on the spring arms 56 and 57 and said arms are slidably su ported on the guides 29;, it being shown in the drawings,

that the arms have their ends remote from the knife 55 ofiset downwardly with respect plied to the. said pins under the guides 29 so that the said nuts prevent the pins from withdrawing from the slots, but at the same time allowing free movement of the arm longitudinally of the guides.

The pins 58 and 59 are of such length that they extend into the path of travel of the studs 62 and 63 projecting from the sides of the chains 40, so that movement of the chains is communicated to the knife when the, studs encounter the pins.

As a means for operating the sprocket chains, a shaft 64 is journaled transversely of the casing 21 and near each side of the casing a sprocket wheel 65 is mounted on the shaft, and each of said sprocket Wheels en.- gages one of the sprocket chains 40. Near the opposite end of the casing 21, stub shafts 66 and 67 are journaled in the sides of the casing, one of which stub shafts being on each side. The stub shaft 66 has a sprocket wheel 68 and the stub shaft 67 has a sprocket wheel 69. The stub shaft 67 extends through the casing and has a crank handle 70-by which the stub shaft is turned. By reason of the connection of the sprocket chains with the sprocket wheels, turning of the crank handle will result in moving the sprocket chains in unison and as the blocks 33 and 31 are connected to the chain, motion of the chain is imparted to the blocks and consequently to the rod 32.

\n arm 71 is mounted to freely rotate on one. of the stub shafts and the arm has two lugs 72 and 73 spaced apart for receiving a stud 7'1 projecting from the side of one of the sprocket chains. so that as the sprocket chain moves bacluvard and forward, the stud 71 engages one of the lugs 72 or 73 and partially rotates the arm 71 according to the direction of movement of the chain. A link 75 is provided for the arm 71 and has one end pivotally mounted on a stud 76 projecting from the face of the arm. The end of the link 75 remote from the arm is connected by a pivot 77 with the lever 78 which lever is mounted on a fulcrum 79. One side of the arm 71 has a pin 80 acting as a stop to limit the rotation of the arm so that the chain may rotate the arm only a predetermined distance.

The upper portions of the partitions 25 have bearings 80 and 81 for shafts 81 and 8L on which the arms 83 and 84 are respectively mounted. The shafts 81 and 82 have hangers 83 and 84; which are connected to an immersing frame 85 by pivots 86 so that as the arms swing, the immersing frame is moved with relation to the casing. A receptacle 87 is preferably placed in the casing and is designed to contain liquid such as a fixing fluid into which the film may be submerged by the immersing frame. The upper ends of the arms 83 and 8+ are connected by a link 85 so that motion communicatcd to one arm is communicated to the other arm .and as the arms operate in unison for communicating motion to the immersing frame, it follows that film delivered to the receptacle 87 will be forced into the liquid. As a means for communicating the motion of the arm 71 to the immersing frame or the hangers supporting the same, the link 75 and the lever 78 heretofore described are interposed between the arm 71 and the arms 81. but in addition to this link and lever just described, there is another element interposed between the lever and the arms 8t which it aetuates, the said member comprising a slotted plate 88: the. upper end of the lever 78 having a pivot 89 movable in the slot of the plate. The plate 88 has a recess 90 merging with the slot, the said recess forming a seat for the pivot- 89 under certain conditions of operation. The plate is furthermore provided with a latch 91 mounted on a pivot 92 of the. plate and the said latch has a. shoulder 93 adapted to engage the pivot 89 so that movement of the lever 78 is communicatcd to the arm as the said lever oscillates. \Vhen the latch is moved from the full line position shown in Fig. 9, to the dotted line position thereof, the lever may oscillate without communicating motion to the arm 84 in one direction.

When the latch 91 is out of engagement with the pivot 89 the outward movement of the lever 78 is effective to lift the immersing frame, but the said frame instead of being positively actuated in its descent, is allowed to descend by gravity.

\Vhen the immersing frame is to be held in elevated position, as for instance, when film is removed from the receptacle, or for any other purpose the plate is adjusted with relation to the pivot 89 so that the said pivot will lie in the recess or notch 90.

In order to guard the stationary knife 51 from the action of the fluids which might be displaced by the immersing frame, the arms -56 and 57 are provided with a supporting bar 91 and the said supporting bar. carries a shield 95 which partially embraces the knife 54 as shown in Fig. 2; the said shield being carried from the stationary knife as the arms 57 are moved to cause the movable knife to approach the stationary knife.

In the operation of the apparatus, the film 108, a length of which is projecting into the receptacle 41, is supposed to have been exposed to the action of light and has been drawn from the exposing chamber and de livered to the said receptacle through the rotation of the feed rollers, heretofore described. Fig'. 2 shows the first or initial position of the developing cutting and conveying apparatus and it will be seen that the rod 32 is normally stationed infront of the film 108 and that it is to be drawn rearwardly to engage the said film and draw it from the receptacle 11 while the film is being held by the rollers 13 and 14, and thereafter, the said film is to be severed by the actuation of the movable knife with respect to the stationary knife. \Vith this understanding of the mode of operation, rotation of the crank 70 will result in communicating motion to the shaft 61 through themeduim of the sprocket chain on one side of the case 21 and through the rotation of the shaft 64, the sprocket chain on the other side of the casing will likewise be moved to the same degree. As the crank 70 is to be moved in aclockwise direction initiatively, the rod 32 will be carried by the sprocket chains toward the rear or right hand end of the apparatus as shown in Fig. 2, being thereby caused to engage the film and draw it from the re ceptaele 41. Upon movement of the sprocket chains the pin 74 of one chain engages the lugs 72 and 73 of the arm 71 and partially rotates the said arm so that movement is communicated to the lever 78 and through such movement, the immersing frame 85 is lifted from the receptacle 87 and the hangers 83 and 84 are elevated above the path.

. gagernent or coaction with the stationary knife so that the film is out after it has been drawn by the rod 32 as stated.

The arm 71 is partially rotated by the action of the chain, but in the travel of the chain, the pins 74: disengage the lugs 72 and 7 3 and continue to travel with the chain while allowing the arm to remain stationary with the parts in the position shown in Fig. 11 where the pin 80 is in engagement with the link serving to lock the parts against movement until such time as the chain is moved in an anti-clockwise direction, causing the return of the pin 74: into engagement with the lugs 72 and 73 and a reversal of movement of the arm 71 so that the parts are again brought to the position shown in Fig. 2, it being understood that in the anti-clockwise movement of the chains, a stud engages each of the pins 58 and 59 to move the arms 56 and 57 to the positions which they are shown to occupy in Fig. 2. After the parts have been brought to the position shown in Fig. 2, the film feeding or drawing rollers are again operated to feed film into the receptacle and the operation is repeated.

As has been heretofore stated, it is possible to positively actuate the immersing frame through the action of the lever 7 8.by causing the latch 91 to lock the pivots 89 in the end of the plate 88, but when the latch is in the position to release the pivot 89, the lever 78 moves the immersing frame in one direction only, that is to say elevates the frame, whereas the frame is allowed to descend by gravity.

' The magazine 20 is provided with any appropriate type of support for the spool 109 and as the type of spool is immaterial, it is not described in detail.

The plate 88 has an apertured lug 110 in which an adjusting screw 111 is threaded, said adjusting screw having its end adapted to bear against the pivot 89 so that said pivot may be held in the recess of the latch 91.

The receptacle 41 has hangers 112 extend ing downwardly to support a drip pan 1-13,

' the said drip pan being provided to receive drippings of material discharged from the faucet 114- in the bottom of the receptacle 41, so that the said receptacle may be conveniently drained.
