PHOTOGRAPH-MACHINE.

Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed May 28, 1910. Serial No. 563,896.

To all whom 'it may concern:

Be it lmown that I, PIERRE V. W. WELSH, of the city of New York, county of Kings, and State of New York, have invented a new and useful Improvement in Photograph-Machines, of which the following is a full, clear, and exact description.

My invention relates to improvements in photograph machines and especially to that type of photograph machines which is used in which photographic plates after being exposed are deposited in a developing composition.

Machines of this character are often somewhat complicated and liable to get out of order, and moreover such machines are liable to require too much nicety of operation and adjustment to enable them to be worked successfully by an amateur.

The object of my invention is to produce a cheap simple machine of this character in which a magazine for holding the plates is conveniently disposed opposite the lens, in which the camera can be readily loaded and unloaded, and to provide further a very con venient means for depositing in the tank the plates after being exposed and also provide a tank which has separate receptacles for each plate so that the plates are not likely to be injured or stuck together, while on the other hand each receptacle or compartment communicates with the others so that one liquid charge acts for the whole.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar reference charac ters indicate corresponding parts in all the views.

Figure 1 is a perspective view of the apparatus embodying my invention. Fig. 2 is a plan view thereof with the cover and hood removed. Fig. 3 is a vertical section on the line 3-3 of Fig. 2. Fig. 4- is a cross section on the line 4-4: of Fig. 3, and Fig. 5 is a detail view showing the spring device for supporting the plunger.

The machine is provided with a camera having a box of any preferred construction, and this is preferably mounted on a tripod 10 in the usual or inany preferred manner, though of course the mounting of the apparatus has nothing to do with the invention. The box or body 10 is provided with a hinged frame 11 carrying a hood 12 of the usual character, so that the operator can insert his hand through the hood and load the magazine in the daytime. body is also provided with a suitable cover 11. All this is common to machines of this character, and no novelty is claimed for the parts already described.

Arranged transversely in the body is a chute 13 which extends horizontally through a hinged fly 14, the latter having its hinges 15 at the bottom so that when desired the fly can be tipped forward and bring the magazine 16 which is carried by the fly, to

the position shown by dotted lines in Fig.

'8, thus enabling it to be easily loaded. The

magazine is a tubular structure comprising in part an inner split tube 17 open at the outer end and carrying a piston 18 which is pressed by a spring 18 so as to force the sensitized plates 19 forward opposite the exposure opening 20 in the fly 14;. The magazine also has an outer tube 21 closed at its outer end and which slips on snugly over.- the inner tube 17 and locks to the same by means of a bayonet joint 22. The exposure opening 20 comes opposite the lens 28 which may be of any usual character but which is preferably one of the form of lenses which are adjustable in and out. The magazine inclines slightly toward the right when standing behind the lens, as this has a tendency to bring the plates 19, hereinafter referred to, into snugger connection with the plunger 36.

Then the fly 14 is tipped up to the Vertical position shown in full lines in Fig. 3, it is held by a catch 24 which can be of any approved kind, but which as shown is vpivoted at 25 in the bracket housing 26, the

latter being supported on the inner side of the body 10, and the catch is pressed into engagement with the fly by a spring 27, but obviously any suitable fastening device can be substituted for the catch. As the fly is engaged by the catch it strikes against a suitable abutment which in the present instance is in the form of a bracket 29 attached to the bottom of the camera, although it can be attached to any other scribed. By this arrangement I avoid the The necessity of making the plunger fit too tight in the chute, and so being liable to get stuck or clogged, while at the same time the accurate movement of the plunger is provided for.

The chute 13 has at one end a downward bend as shown at 13 which opens from the bottom of the body 10, and through this opening the plates 19 are delivered into the developing tank 30 which is supported on the bottom of the body in a suitable manner to permit it to turn, a convenient means being the thumb screw 31 which engages the boss 32 on the under side of the body 10. The tank has a suitable cover 33 with an opening therethrough which alines with and forms a continuation of the opening 13 and it has another opening 3a in the outer part as shown clearly in Fig. 2 and through which the plates after developing may be lifted from the bath. The plates can be removed in any preferred way, and a convenient means is to use an ordinary horse shoe magnet for the purpose. The opening 34; has a cover 35 which is pivoted to the cover 33, and can be turned so as to cover or expose the opening 34 as desired. The tank 30 can be turned every time a plate is deposited so as to bring another compartment 36 below the opening 13*, and a spring pawl 30 engages the notches 30 in the tank and holds the tank temporarily stationary,

but the pawl is so light that the tank can be readily turned by hand as desired.

To provide for pushing the plates 19 away from the exposure opening and into the developer, a plunger 36 is used which is manually operated and slides back and forth in the chute 13, the plunger being of approximately the same thickness as one of the plates 19. As a convenient means of operating the plunger, I employ a handle or rod 37 which can be pushed out and in, and has at its outer end a milled head 37 to enable it to be conveniently grasped. Tts inner end is screwed to the plunger as shown at 39, and one wall of the chute is enlarged as shown at 28 to provide for the plunger.

By reference to Fig. 5 it will be seen that the plunger 36" is slightly concavo-convex, and that the walls of the chute 13 are con caved so that one of the plates 20 will rest on its edges in the chute and not touch the sides. Then as the plunger is moved to push the plate forward, it will pass by the next plate with its concaved side opposite the said next plate so that it will not scratch or injure the plate, while the plate being pushed, bearing as it does only on its edges, will likewise not be scratched by the Walls of the chute.

In operation, as soon as an exposure is made, the operator pushes in the handle 37 and the plunger 36* pushes forward one of the plates 19 which drops through the open ing 13 into one of the compartments 36 of the developing tank. In case any plate should stick I have provided an opening 31 in the top of the chute so that the operator can reach in with a wire or other fine instrument and dislodge the stuck plate. After the plate is dropped, the operator turns the tank 30 one notch so as to bring a fresh compartment beneath the opening 13 and the handle 37 is again pushed in and out so as to deposit the next plate, and so on.

It will be seen that I provide a very simple mechanism for accomplishing the desired end, and it will further be seen that while the developing tank has separate compartments for each plate, all the compartments are in communication, as they are radially arranged and one bath serves for all.

It will of course be understood that some of the details which I have described may be changed without affecting the principle of the invention, the essential things of which are the general arrangement of the fly with its magazine, the chute, and the developing tank of the construction shown.

It will also be readily seen that the camera can be used without the particular form of developing tank shown, but the two work together, and it is better to use this form of tank.

I claim l. A camera having a fly tiltable in relation to the box of the camera, said fly having a chute therein and an opening opposite "the lens of the camera, a magazine connected WVlllll the fly and dlscharging plates opposite the aforesaid opening, and a plunger sliding within the chute for pushing the plates successively along the chute.
