Patented June 2, 1931 EUGENE WASYLENKO, OF CHESTER, PENNSYLVANIA APPARATUS FOR DEVELOPING AND PRINTING PICTURES Application filed September 26, 1929. Serial No. 395,441.

This invention relates to improvements in apparatus for developing and printing pictures of the kind usually supplied in packs.

The primary object of this invention is to provide a compact apparatus adapted to perform both printing and developin of the negative film, without making rea y for a lot of other apparatus.

A still further object of this invention is to provide a device of the above character adapted to be carried from one place to another without requiring other instruments to perform the necessary operations on the film negative.

A still further object of this invention is to provide a device ofthe above mentioned character adapted to accommodate the usual type of roll pack films of any desired size or dimension;

A still further object of this invention is to provide a device of the above mentioned character which may be cheaply and economically manufactured and which may be operated by an amateur photographer with remarkable ease,

Other objects and advantages of the in-" vention will become apparent during the course of the following description forming a part of this specification and in' which,

In the drawings forming ,a art of this specification wherein is shown or the purpose of illustrating the invention, thenumeral 5, designates a receptacle formed of wood or other material and is made waterproof by a hard rubber receptacle 6 which is snugly fitted into the dimensions of the router receptacle 5. A cover 7 is provided and is chambered at 8, on its side and end walls to receive the free edge of the waterproof container 6. On each of the sides of the cover 7 is mounted a plate 9, by means of wood screws, for providing pivoted latches 10,- adapted to engage hooks 11, formed on the plates 12, which are secured to each side of the receptacle 5.

The cover 7 is also provided with a longitudinal rib 13 for forming a space 14 between one of the side walls whereby a compartment 15 is formed. Mounted at opposite ends of the compartment 15 is a pulley 16 mounted upon shaft 17 and also supported in

openings

18 and 19 formed in the longitudinal rib 13 and the side wall respectively as more clearly shown in F ig; 6. Upon the shaft 17 is mounted a coil spring 20 in order to extend the enlarged portion 21 of the shaft 17 into engagement with a present day film roll which is designated as at 22 and is rovided with the usual metal flange 23 and t e usual opening 24 .and having the film receiving slot 25. The construction above described, is the same at both ends of the receptacle cover 7 and both of the pulleys 16 are connected by means of a belt 26 WhlCh passes therearound and provides for the simultaneous rotation of the same in the same direction. Each shaft 17 is screw threaded as at 27 and is provided with a thumb nut 28 whereby a handle 29 ma be secured to one or both of the shafts 1 as the case may require. Threaded on one of the shafts 17 is a locking plate 29 having a longitudinal slot 30 with an intermediate enlarged portion 31 for receiving the shaft 17 The sliding lock 29 is mounted upon the for holding the shaft 17 in its operative position whereby the enlarged end 21 of the shaft will be selectively secured to the film roll or spool 22.

-A pair of downwardly descending film supports 36 are provided adjacent the film holding spool 22 whereby the. film will be guided downwardly from the roll and in close relation to the water proof container 6. The

uiding rods 36 are secured to the cover 7 y means of screws 27 and the film engaging portions of the guides 36 are arcuately curved to conform to the general contour of the sets A freely rotatable roll 40 is removably secured to the longitudinal rib 13 at one of its side walls by spring clips 41 engaging the usual tyreof opening formed in the ends of the woo en roller 40. The roll 40 is provided with metallic end flanges 42 which are also of the usual construction.

It will be noted that the opposite ends of the film holding spools 22 are engaged by spring members 43 mounted in a cut-away ortion 44 in one side of the cover 7 and held thereto by means of a screw 45 which passes through a flanged portion 46 of the spring member 43. The spring member 43 isalso provided with a lug 47 which is adapted to engage in the end opening 48 of the roll 22. The cover 7 is provided with a flexible handle 50 secured by stra end attaching de vices 51 to the side wall 0 the cover whereby the device may be easily carried from place to place. In the top wall of the cover 7 is provided angular openings 52 which are presented at an angle to the film holding spools whereby the film from the spool may be directed through the opening 52' and across a portion of the cover 7 for the purpose of printing.

A filler spout 53 is shown as communicating with the cover 7 and the filler spout 53 is provided with a goose neck which terminates in the side wall of the receptacle as at 54 whereby the receptacle may be filled with the usual developing liquid.

Any means may be provided for bracing the longitudinal rib 15 and as shown a frame supporting bar 55 is employed and has its opposite endssecured to the longitudinal rib 15 and one side of the cover by means of wood screws 56.

For the purpose of illustrating the operation of the device attention is directed to Figs. 8 and 9 wherein are shown the films to be developed and printed secured in operative position. Figure 8 illustrates the first step of developing a film and as shown, the

film pack on the spool 40 is the usual type of film spool adapted to fit different dimensions' of cameras and which may be removed therefrom and placed directly in the cover 7 by means of the spring clip 41. Usually in this type of film spool, the negative is protected by means of a cover strip A which is formed of ordinary dark paper and is only for the purpose of protecting the coiled surfaces of the negative strip B. One end of the negative strip B-is secured to one of the film spools'22, while the other black paper strip A is secured to the adjacent film spool22 for the purpose of removing the blankpaper from the negative. At the same time when this operation isgoing on, the negative B is being developed in the tank 6 in which-is placed the usual developing fluid well known in the art. After the protective covering or paper A has been removed from the negative film B and the negative film B has been wound upon one of the rollers 22 which is at the farther end of the cover 7,- the same spool is removed and is exchanged for the opposite spool 22 as shown in Fi re 9. The same is placed on the rotatable shaft 17 in exchange for the rolls which unwind the protective covering from the film pack originally contained on the spool 40. The spool 40 is then provided with a printing paper B which is threaded upwardly through one of the openings 52 and downwardlythrough the remote opening 52 of the cover 7 whereby the end is secured to an empty spool mounted on the shaft 17. After the printing paper B has been placed in position, the negative B is also threaded upwardly through one of the openings '52 which places it above the printing paper for printing the negative B. The ends of .the printing paper B and the negative B are both secured to the same opposite roll and are supposed to be simultaneously wound thereupon, after which they are separated while receiving the fixing solution which is well known and common in the art.

It is to be understood that various changes in the shape, size and arrangement of parts shown and described may be resorted to without departing from the spirit and scope of the invention or the scope of the sub-joined claims. It is also to be understood that the shape and construction of the film supporting rollers are of usual construction as sold or furnished with a pack of films when the same are purchased.

I claim 1.
