To all whom it may concern:

e it known that I, GEORGE C. BEIDLER, a citizen of the United States of America, residing at 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 more particularly to an improvement designed to simplify the construction of the apparatus patented to me January 23, 1906, numbered 810,388, the simplified construction being also provided with motor driven mechanism and means actuated by the mechanism for controlling the motor.

An object of this invention is to produce a developing apparatus in operative relation to a photographing apparatus, the said developing apparatus having a tank or receptacle to contain fluid with relation to which a drum rotates. the said drum displacing the developing fluid to such an extent as to make it possible to use a minimum quantity of fluid for the purpose of immersing a print.

A further object of the invention is to provide a conveyer or carrying device preferabl comprising an apron or belt with which a flexible device such as a chain or the like coacts to retain the print on the apron or belt while the said' print is being carried through the developing fluid.

I have found that an apparatus made in accordance with this invention will require a very short belt or apron for the reason that a single developing tank is employed and the print is delivered to a pan or receptacle containing the fixing fluid and instead of conveying the prints through a'tank containing the fixing fluid, the said prints are simply delivered to the fixing fluid and are allowed to sink therein and the may be removed by hand at the convenience of the operator. In using this apparatus, it is-of course desirable to wash the prints after they are removed from the fixing fluid and that can be accomplished in any suitable wav.

'ith the foregoing and other objects in view. the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, in which- Figure 1, illustrates a view in elevation showlng a photographing and developing apparatus embodying the invention; Fig. illustrates a sectional view of a fragment of the sald apparatus taken approximately on the line 2-2 of Fig. 3; Fig. 3, illustrates a view in elevation of the rear of the machine; Figs; 4 and 5, illustrate enlarged views of clutch mechanism utilized in connectlon with a motor; Fig. 6 illustrates a sectlonal view on the dotted line 6 of Fig. 5), the worm being omitted and the shaft bemg shown partly in section and partlv in elevation; Fig. 7 illustrates an enlarged sectional view of the conveying and developmg portion of the apparatus; Fig. 8 illustrates a detail view of the end of the developlng portion of the apparatus; Fig. 9 illustrates a view in elevation showing the opposlte end thereof; Fig. 10 illustrates an enlarged view of a belt adjusting mechanism; Fig. 11 illustrates a view in elevation of mechanism for operating a dog for d sengaging said dog from a drum.

In these drawings A, indicates a casing for the developing apparatus covered by magazine B, adapted to contain a supplv of film. The side of the magazine has an exposing chamber, and a camera D is applied to the side of the magazine for exposing the film in the exposing chamber to light. i

The construction of the magazine, exposing chamber and camera may be similar to that of like'parts disclosed in my patent hereinbefore referred to. and will, therefore. not be described in detail. The magazine is preferably above the casing A. and acts as a cover for said casing. The casing is supported on the base a.

One side of the casing has an opening a and below the opening brackets similar to the bracket (1 are attached to the casing. A pan or receptacle (1, is supported by the brackets a, and said pan projects into the casing through the opening (4 The purpose of the receptacle a, is to contain a fixing fluid into which developed prints are delivered. Under ordinary conditions, the light would not be sufliciently strong to atfect a developed print coming from the dcvelop'ing apparatus (to be hereinafter described) but for the purpose of providing a through the front of the casing.

safeguard against action of light on the developed print, a hood a, is removably secured to the casing in any appropriate man- 1101'. The casing contains a tank or receptacle E, adapted to receive developing fluid, and said tank may have ends a, in which the shafts F and G, are journaled, or said shafts may be otherwise suitably journaled in operative relation to the receptacle.

The receptacle may be supported by the plates H, secured to the base, and said receptacle has a drain pipe I, to which the cock J, is connected, said cock extending A drip pan K, is located under the receptacle and is provided with a drain nipple k, eXtenCling through the base. The drip pan is provided to collect the drippings from the chains, conveyers and rollers, to be presently described. Shafts extend between the plates H, and support the pan K, and said shafts carry pulleys if, over which said chains travel. The shaft F is adapted to extend into the stub shaft 20 or the said stub shaft may be otherwise connected to the shaft F for the purpose of driving said shaft, and said stub shaft is provided with a sleeve 21, provided with a shoulder 22, at one end and has its opposite end screw threaded as shown at 23. The sleeve is further provided with a longitudinally disposed groove 21. The sleeve is anchored on the stub shaft at any position desired through the medium of a set screw 25. A worm wheel 26 has its hub rotatable on the sleeve and said worm wheel has its side recessed to form a clutch member as shown at 27, the said worm wheel being engaged by a worm 28, mounted on the shaft 29, of the motor 30, the said motor being here shown as an electrically driven motor, although I do not wish to be limited with respect to the type of motor employed. The clutch member-31, is slidable on the sleeve and has a friction face 32, adapted to act in conjunction with the clutch member of the worm wheel 26. The hub of the clutch member 31, is provided with screws 33 which are threaded therein and have shanks extending into the groove 24, in the sleeve. The function of these screws and their shanks is topermit the clutch member 31, to move longitudinally of the sleeve but to prevent rotation of the clutch member 31 on the sleeve. In other words, the ollice of the clnteh member 31.. is to communicate motion of the worm wheel 26 to the. sleeve and as the sleeve in turn is coupled to the stub shaft. it follows that the stub shaft will be rotated and as the stub shaft is connected to the shaft F. power is communicated to the mechanism for feeding and conveving film. A spring 34 encircles a portion of the sleeve and has one end hear ing against the clutch member 31, whereas the opposite end of the said spring 3 bears a gainst the nut which engages the threads 23 on the sleeve. lly means of this nut, tension of the spring 3-l' is controlled. The rear ends of the shafts F and G, have sprocket wheels 7' and respectively and said sprocket wheels are connected by a sprocket chain M, by which motion of the shaft F is communicated to the shaft G.

A frame N, is supported above the recep-' tacle and said frame has a denendin arm n, at each end forming supports for the rotatable drum 0. The drum may be hollow and is preferably comparatively large with respect to the receptacle in which it is supported for, by this construction, the developing fluid contained in the receptacle is displaced and a small quantity of the developing fluid will be suiiicient to completely immerse a print as it is carried by the drum. One end of the drum is provided with a peripheral gear P, meshing with a pinion Q. rotatable on a stud q, projecting from one of the arms. The pinion Q, is driven by a gear wheel R, on a shaft S, the said gear wheel R, taking motion from a gear wheel R, mounted on the shaft Gr.

The end of the drum opposite the peripheral gear P is recessed to form a shoulder T, and said shoulder is engaged by a dog U, which is longitudinally slidably mounted on a stud V, the said dog being pulled downwardly by the spring '0. The spring is shown in Figs. 2 and 8 as being connected to the dog and to the frame N. Under ordinary conditions, the weight of the dog will be suflicient to cause it to move longitudinally, but in order to insure positive action the spring 1), is provided. The object of the dog U, is to arrest the drum at each complete rotation of the said drum and as the shoulder of the drum contacts the end of the'dog, the dog is elevated slightly until it has moved a. distance equal to the length of the slot 1). The dog U, is further utilized to operate the switch 36, which is of a type to close under the tension of a spring when the dog U disengages said switch. That is to say, when the dog is elevated through its engagement with the drum, the upper end of the said dog engagesthe switch and opens it, thereby cutting out current to the motor but on the descent of the dog ll and its disengagement with the switch the spring of the switch operates to cause an engagement of the contacts of the switch thereby completing circuit through the switch to the motor.

As shown in the drawing. the conductor conduit 37, extends inside of the case to contain the conductors 38 and 39 projecting from the coupling 40, to the terminals of the switch. 41, is a conductor which may be connected to any source of electrical supply 2, to either wire 38 or 39 in the conduit 37.

One wire from the switch to the motor is extended through the conduit 27, and through the box 42. In fact, any appropriate wiring may be employed for connecting a motor tothe source of electrical supply through a switch or cut out operated by mechanism employed in connection with the apparatus. By this arrangement, the mechanism is broughtto rest at such time as the print is immersed in the developing fluid contained in the tank and the mechanism cannot be again operated until the dog U, is moved out of engagement with the shoulder T. This is accomplished by the lever W, which is on a short shaft projecting through the casing and having a handle 63. Pressure on the outer end of the handle results in pressure on the upper end of the dog which will cause the lower end of the dog to swing out of engagement with the shoulder. When the lower end of the dog is clear'of the shoulder T, it is free to drop so that its end clears the shoulder T, of the drum and the switch will be closed to conduct current to the motor for the purpose of starting the motor as heretofore indicated. The periphery of the drum being cut away as indicated, also permits the arm X, to be moved with relation to the dog w, on the feeding and cutting roller to be hereinafter referred to.

The arm X, is held normally pulled down by means of the spring .I', and when the drum rotates sutliciently to bring the recessed portion thereof under the arm X, the said arm is pulled down so that its upper end clears the end of the dog '10. hen the dog is released, the spring 1: forces its nose into engagement with the ratchet wheel Y, on the shaft 3 and hence rotation of the shaft is communicated to the feeding roller Z, it being understood that the dog "10, is pivoted on the feeding roller and that the spring 10, holds the nose of the dog normally in engagement with the ratchet wheel Y. For the purpose of holding the arm X, normally elevated a cam Z, is mounted on the frame X, and may be moved by a knob (34 outside the casing to hold the arm normally elevated in which position the said arm will hold the dog out of engagement with the ratchet wheel and the shaft I may be rotated without operating the feeding roller.' lVhen a print is caused to travel between the feeding roller Z. and the rollerz. it is punctured at each rotation of the feeding roller by the blade Z on the feeding roller and the print is then directed between the two rollers 2 ant .2 and fromthere to the interior of the developing apparatus where the print is delivered to the conveyer, con sisting of the chain 11, and the belt S In operation, when the parts are in the position shown in Fig. 2, the cam Z is rotated by the operation of the knob (it to disengage the arm X and the lever \V is operated by the handle to throw the end of the dog out of engagement with the shoulder T, the drum will be free to rotate for the reason that provision is made for permitting the dog to move longitudinally by the slot therein in order that the end of the dog may travel past the said shoulder of the drum. Power being applied to the shaft F, the shaft G will be rotated through the medium of the sprocket wheels and chain and the gear Wheel R, taking motion from the shaft G, heretofore described, will turn the gear wheel Q, and communicate motion to the drum. lVhen the drum has been rotated slightly, the arm X, descends into the recess of the drum and the upper end of said arm clears the dog 'w, and permits the spring 10' to force the nose of the dog into engagement with the'ratchet wheel. By this means, the motion of the shaft 3 is communicated to the feeding and cutting roller Z, and the print is drawn between the roller Z, and the roller 2, and punctured, that is to say, a print isrpunctured with each complete rotation of the roller Z, and said print is directed between the rollers 2' and 2 After the arm X has been elevated to the periphery of the drum, the upper end of the said arm stands in the path of travel of the dog to, as it is carried around by the feeding and cutting roller Z, and when the said dog contacts the arm, the nose of the dog is thrown out of engagement with the ratchet wheel and the shaft 7 is permitted to rotate independently of the feeding and cutting roller. Though the feeding and cutting roller comes to rest, the

rollers

2 and 2 continue to rotate, drawing the film down- 13.3 ward and causing the film in engagement with the said rollers .2 and 2 to be severed from the body of the film on the puncture line heretofore referred to. The film thus severed will be delivered to the con- 1 veyer consisting of the chain and belt heretofore mentioned. The rollers 2' and 2 rotate during the time the mechanism is running as there is no provision for arresting their movement but the feeding-and cutting 115 rollers are geared together and when the shaft 3 rotates independently of the feeding and cutting rollers as described above, the said feeding and cutting rollers are without power to drive them and hence they remain 120 stationary while the rollers 2' and .2 continue their rotation.

The shaft ;2 is driven through the medium of a gear wheel 3 meshing with a gear wheel 2 the ratchet wheel Y on the shaft 125 y being engaged by the dog X pivoted on the gear wheel 3 for the purpose of coupling the gear wheel y to the ratchet wheel. The wheel 3 is normally free to rotate on the shaft 3/ whereas the ratchet wheel Y is 56- tent to cause the said cured to rotate with the shaft. It follows, therefore, that when the dog X couples the wheel y to the ratchet wheel Y, the motion of the wheel will be communicated to the shaft y. j

The roller Z is positively driven by a gear wheel 2 meshing with the peripheral gear 2*, on the feeding and cutting roller Z, and the rollers .2 and 2 are preferably positively driven by being geared together at one end.

The frame N, is provided with a roller N which is relatively small, around which a belt or apron travels and it has been found in practice that a print after having been carried through the developing tank by means of the belt or apron and the chains which hold the print on the belt or apron,

said print being separated, will adhere to the surface of the belt or apron to a sufficient exprint to travel with the belt or apron from the point of disengagement of the chain with the print, which is at the shaft F, until the said belt or apron starts to encircle the roller N, but owing to the abruptness of the turn over the roller, the said print breaks away from the belt or apron and will, by gravity, descend into the pan or receptacle a which contains the fixing fluid. It has been found that the print, as it is fed from the developing apparatus, will be supported by the fixing fluid in the tank or receptacle and will travel longitudinally of the pan as it is being fed. from the developing apparatus. In other words, the edge of the film will not fall into the pan or receptacle vertically, but will travel sufliciently therein to cause the said film to lie fiat in the contents of said pan or receptacle, so that the prints will lie one upon the other.

The shaft F, is provided with a sprocket wheel adapted to engage the sprocket chain H, which runs over the sprocket wheel 4C5, on. the shaft 46, which shaft is utilized to communicate motion to a carrier for supporting the films as they are projected from the developing apparatus. The shaft 46, has sprocket wheels 47, thereon which are engaged by chains 48, which chains run over the sprocket wheels 49 and 50 on a suitable frame 65. The construction of this carrier is similar in all respects to that disclosed in my application number 492, 112, filed April 27, 1909. and the carrier will not, therefore,

,be described in detail. I have, however, provided a film dislodging arm 50 which is suspended from the shaft 51, and the said arm 50, has its ends. depending into the path of travel of the rods 52 on the chains 48 so that as said rods pass under the arm with the film lying thereon, the said film is engaged by the end of the arm and is removed from the rods before the said rods have paslsed beyond the outer edge of the receptac e.

operate the switch The belt may be tightened or adjusted to make it run straight on the shaft F, through the medium of an arm 53, pivotally mounted on the frame and having a lug 5% which is engaged by the end of a. rod 55', which rod is threaded in the lug 56. By rotating the rod 55, the arm is ralsed or lowered and as the shaft F, is journaled in the arm, the Inovement of the shaft affects the belt which runs over the said shaft. The rod 55, extends through the bottom of the casing in order that it may be reached from the outside for the purpose of manipulating the parts to efi'ect the proper adjustment.

In addition to the hand operated means for tripping the dog U, I employ. a flexible connection 57, run over a pulley 58, andconnected to a bell crank 59 for tripping the mechanism to start the motor. As shown, the bell crank is pivoted on a bracket 60, secured to one of the legs of the casing and the said bell crank has another connection 61 which extends up into the casing and is so connected to trip the mechanism as heretofore stated. Any appropriate means may be provided for pulling the flexible connection 57. The stud 38 on the dog is engaged by an end of the lever 61f and as the flexible connection is pulled, the lever 61 moves the dog U on its pivot.

The clutch mechanism more particularly shown in Figs. *1, 5, and 6, is provided for the purpose of coupling the motor to the shaft F for driving the mechanism and' the said clutch is furthermore provided so that the starting and stopping of the feeding and operating mechanism of the apparatus may not be jarred or unduly strained by the sudden starting or stopping of the motor and it furthermore .provides for arresting the mechanism at predetermined cycles of operation, though the motor has not come to rest at the time the mechanism is arrested.

While the purposes of the elements and their relation to coacting elements and the functions to be performed have been described in connection with the description of the said elements, a description of a cycle of operation of the said elements will be given. Assuming that a portion of film has been exposed to actinic light while the mechanism is at rest, that is to say when the parts are in the position shown in Fig. 2 and it is desired to draw the said film from the exposing chamber and subject it to the developing process, the handle 63 is operated to cause the dog to be disengaged from the drum and simultaneously therewith to 36 for the purpose of establishing a circuit from the source of electricity to the motor. Prior to starting the motor by the means just mentioned, the cam Z will have been moved by rotating the knob (Hon the outside of the casing, so that the arm X is released. When the motor starts, the drum will be rotated and the lower end of the arm will fall into the recess or cut. out portion of the drum and its upper end will release the ratchet or dog IV permitting it to engage the ratchet wheel on the shaft 3 Owing to the fact that the shaft y is positively driven with the other mechanism, the rotation of the said shaft is communicated to the feeding roller by ieason of the fact that the dog or ratchet W is pivoted on said feed roller. It is seen, by an inspection of Fig. 2, that the descent of the arm X into the recess of the drum is of short duration, owing to the fact that the recess is restricted and as said recess terminates in a cam, the lower end of the arm is raised to the periphery of'the drum and rides on said drum during its rotation. The elevation of the arm results in forcing its upper end into the path of travel of the dog orratchet carried by the feed roller and hence when said feed roller has made one complete rotation, the dog or ratchet is swung on its pivot because of its contact with the upper end of the arm and hence the shaft 3 and the feeding roller are disconnected at the time the feeding roll is arrested by reason of the contact between the dog or ratchet and the upper end of the arm. 7 During the rotation of the feed roller a predetermined length of material has been drawn from the exposing chamber and owing to the presence of the knife, which is assbciated with the feeding and cutting rollers, the length of material so drawn is severed or cut. The length of material that has been drawn by the feeding roll is delivered between the rollers z and 2: and to the conveyer which has been described. The relation of parts is such that the rollers z and 2 and the conveyer continue to operate and the relation of parts is such that the film or material cut is immersed in the liquid contained in the tank or receptacle in which the drum is rotatable so that the said film is immersed and is subjected to the action of the fluid in the receptacle, which fluid is preferably developing fluid. The operation of the drum and conveyer continues, in this apparatus, while the drum is making one complete rotation, and the current to the motor is interrupted by the action of the dog II, the lower end of which engages the shoulder T as the drum is rotated, said (lIlUIl forcing the dog longitudinally so that it operates the switch, as stated, for interrupting the current to the motor. As the dog positively arrests the drum, all the parts coupled to it are likewise arrested, and, notwithstanding, the motor has a certain momentum, there is no undue strain on the parts of the apparatus for the reason that the clutch-interposed between the motor and the said mechanism yields and permits the motor to run to a limited extent after the parts have been arrested. During the time the print is in the developing fluid, another exposure of the sensitized element which is in the exposing chamber is made and at the time that the last exposed film is being drawn from the exposing chamber and cut, the previously submerged film is carried by the conveyer from the casing and is delivered to the receptacle designed for containing the hypo or fixing fluid, the said receptacle for the fixing fluid in this instance having associated with it a carrier which has been described, so that the fihn is partially supported by the carrier and partially by the conveyer, by'which medium, it is delivered tolthxla receptacle containing the fixing fluid.
