HARRY FORD, OF LYNDON, KANSAS.

PECIFICATION forming part of Letters Patent No. 385,607, dated July 3, 1888.

Application filed March To aZZ whom it may concern:

Be it known that l, HARRY FORD, a citizen of the United States of America, residing at Lyndon, in the county of Osage and State of Kansas, have invented certain new and useful Improvements in Mechanical Photographic Baths; and I do hereby declare the following to be a full, clear, and exaetdescription of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specitication.

My invention relates to an apparatus for washing photographic prints to render them free from chemicals prior to mounting, the object being to provide a receptacle within which the photographic prints are placed for washing, so that they can be automatically washed by changing the water in the receptacle as frequently as desired, and after the last washing the water will be automatically cut off to hold the tray or receptacle filled.

My invention consists, broadly, in the construction and combination of the parts to attain the above ends, as will be hereinafter fully set forth.

In the accompanying drawings, which illustrate my inventiqp, Figure l is a perspective view. Fig. 2 is a side view; Fig. 3, a plan view, and Fig. 4 a sectional view on line a: a" of Fig. Fig. 5 is a detail view in rear elevation of the ratchetdisk, showing the pawl and limitingpins thereof mounted on said disk. I

A refers to areceptacle or tray in which the photographic prints are placed when it is desired to wash them subsequent to fixing, to re move the chemicals therefrom prior to mounting. This tray may be of any ordinary construction. To one side or end thereof is secured a pipe, B, which leads into the reeepta- This pipe is provided at a suitable point with a valve or stopcock, b, and the upper end thereof has a liexiblc pipe which connects with a water-supply. The upper end of this pipe B is shown secured to the side of the receptacle by an ordinary staple.

The turning-valve of the stop-cock b has rigidly secured at its outer end aslotted arm O, and rear of said slotted arm is secured a bar, 0, which is bent to engage with the inner end of the valve. to which it is rigidly secured;

and this arm 0, adjacent to the valve-stem, has a projection, c, to which a pivoted pawl, D, is secured. The slotted arm 0 and bar 0 are rigidly connected to each other, and when swung operate the valve to open or close the same, the swing movement being limited by pins a and a projecting from the tray.

To the side of the tray A, below the upper edge and at a suitable distance from the pipe B, is rigidly secured an outwardly-projecting bracket, E, which has perforated side lugs for the reception of a pivoted pin for securing thereto a latch-bar, F, the outer edge of which is notched atf for engagement with the bar 0 when it is raised on a line therewith. The bar F tapers toward its lower end, as shown, to which is pivoted a pawl, G, adapted to fold against the inner straight edge of the latch-bar and swing downwardly to engage with the side of the tray when the latch-bar is thrown out, as shown in Figs. 1 and 4. The downward movement of the pawl G islimited by a staple, g, which is secured on a vertical line therewith near the lower edge of the tray.

The pawl G is struck up of a piece of sheet metahthe sides thereof being turned. to lie over the latch-bar. The upper edge of the latchbar above the notchf and about on aline with the pivot-pin is provided with a projecting catch, g, withwhieh a pin attached to a ratchetwheel engages.

H refers to a ratchet-disk suitably journaled to the side of the tray A, the ratchet teeth 11 thereof being numbered, as shown, and with these ratchet-teeth the pawl D engages to advance the disk one tooth every time the valve is operated. To the face of this disk is secured a pin, 2, which engages with the catch y" when the disk has been moved sufficiently to bring them in contact with each other, this contact taking place when the pawl D engages with the ratchettooth adjacent to the one indicated by the numeral 1.

To the rear side of the disk H is pivoted a pawl, I, which has a bent end to engage with the ratchetteeth on the sector K. The movement of this pivoted pawl is limited by pins It It, so that it will not swing excessively on its pivot when the ratchet-disk H is turned. The

ratchet-disk is held at a suitable distance from the tray by a collar, between which and the disk is placed a spring-washer.

To the lower edge of the tray is secured a bearing for an outwardly-prejecting pin, L, which carries adjacent to the tray a collar, M, to which is rigidly secured the seetorK,providcd on one edge with ratchet-teeth m, with which the pawl I, carried by the ratchet-disk, en gages.

At a suitable angle with the sector K pro jects an arm, K, which is also rigidly secured to the collar M, its outer end being formed into a hook for receiving the outer end of the dischargespout.

The discharge-pipe P is connected by a flexible section, P, with an elbow, p, which enters the bottom of the tray, said elbow being so lo cated that the lower edge of the sector K will engage therewith when it is fully depressed. The sector K and arm K, being both rigidly secured to the same pivoted collar M, will of course move in unison. The outwardly-pro jecting pin L also secures pivotally in place the water-tank O, which is sector-shaped and has an opening in its upper side, into which the water from the pipe P will be discharged. The bottom of this tank is provided with an outlet, 0, above which a screen is placed.

This dischargeopening is quite small when compared with the capacity of the pipe P.

To one side of the tank 0 is rigidly secured an arm, R, at the outer end of which is formed a socket, R, which may be provided with a set-screw, 1'; or the arm may be formed with notches to engage with a projection on the socket. \Vithin the socketslides a bar, S,earrying at one end a weight, NV, having a pin with an anti-friction roller thereon, which engages With a slot in the arm 0.

The capacity of the water-pipe B may be greater than the capacity of the dischargepipe, and the opening 0 in the tank is less than the diameter of the pipe P.

If desired, the tray may be provided with an overflow-opening near its upper edge.

In practice it is intended that the edge of the receptacle A be placed over a sink and the pipe B connected by a flexible tube to the watersupply.

One mode of operating my invention is as follows: The disk-wheel i1 is turned by hand until the pawl D engages with the desired ratchet-tooth on the periphery of the wheel. For example, if it is desired to give a print six baths, the pawl will be placed in the ratchet-tooth indicated by the numeral 6. Thetank O and slotted arm 0 are then placed in the position shown in Fig. 2 of the drawings, which will bring the other parts in proper position, the cock 0 being turned to admit water to the tray. When the water fills the tray to the level of the end of the discharge-pipe P, it will flow through the same into the tank 0, and as the water will run out of said tank very slowly the weight thereof will soon 0verbalance the weight \V, and the tank drop, this movement raising the weight W, which will carry with it the slotted arm 0, and at the same time retract the pawl D to engage with the next ratchet-tooth on the disk H. \Vhen the arm 0 is raised to a horizontal position, the water will be cut off and the waterin the tray A will gradually run out till empty,after which the water in the tank 0 will run out of the opening therein slowly, and the next movement will be when said tank is emptied and counterbalanced by the weight WV, which will open the valve b and advance theratchet-disk one tooth. This operation is carried on successively until the prints are given the desired number of baths.

It will be observed that the pawl I, carried by the disk H, is continuously moved toward the sector K. and when the final washing has been given, this paw]. will engage with one of the teeth on the sector and hold the same down and the arm K elevated. The weight of the waterin the tank 0 willthen elevate the arm Gandbar O,which,in their upward movement,willengage with the notch f in the latch bar to throw thelower end thereof outwardly, and cause the pawl g to fall and hold it in an outward position, as shown in Fig. 4, thereby holding the parts in the position shown in Fig. l of the drawings, so that the receptacle A will be full of water. The pin '6 upon the ratchetdisk engages with the outwardly-projecting stud or catch 9 on the latch-bar to move said latch-bar slightly outward simultaneously with the engagement of the pawl J with the sector K.

When it is desired to arrange the parts of the hereinbeforedescribed device so that the discharge-pipe P will be at different heights to regulate the depth of waterin the receptacle A, the weight- WV, carried by the bar S, is moved out of the socket R and secured by the set-screw. By adjusting the weight in the socket the movement of the tank and the parts attached thereto and the sector are varied.

The arm K rests upon the t-ank and is moved thereby until it is held in a raised position by the engagement of the pawl carried by the disk H with the sector.

I do not wish to limit myself to the precise construction or form of the parts illustrated, and I reserve the right to modify my invention within the spirit and scope of the claims.

The device may be used not only for washing photographic prints, but for other purposes where it is desired thatsuccessive baths of clean water may be given for any purposes.
