This invention relates to a print washerA for the use of photographers, and has for its object to provide an apparatus which will be convenient 1n use and will be eective in operation for washing and removing all acids from the prints.

One of the objects is to provide a rotatable washer which may be attached to a service pipe of a water works system, these service 1o pipes being generally found in oflices, workshops and photograph galleries.

Another object is to provide such a construction that the prints, while conned in the washer, may move freely therein and will be presented at various angles to the flow of water which moves against them to effect a thorough washinoand cleansing.

Still another object is to provide lan apparatus for washing photographic printswhich will dispense with manual handling of the prints.

The invention includes an apparatus for washing prints which consists of few and simple parts so that it may be manufactured at a limited expense and will be durable in use.

With the above objects in view and others to be mentioned hereinafter the invention presents a new and useful construction, combination and arrangement of parts as described herein and claimed and as illustrated in the accompanying drawing, it being understood that changes may be made in size, proportion and minor details, said changes being determined by the scope of the invention as claimed.

In the drawing, Fig. 1 is a View of the print Washer in longitudinal section. Fig.

, 2 isa view of the same in .transverse section.

Fig. 3 is a plan View of the print washer.

Referring now to the drawing for a more particular description, I provide a receptacle 4 for containing water and through which water may be moved, its bottom 5 having a longitudinal curvature as best shown in Fig. 1 of-the drawing to facilitate the movement of -viiowing water. This receptacle may be constructed to advantage of sheet metal. It preferably is provided at its top with a rolled vedge as indicated at 6, and may be supported.

in an upright position by any suitable means, a base 7 of any suitable material being provided for this purpose.

Numeral 8 indicates an intake water pipe which projects downwardly from the top of the receptacle to terminate near its curved bottom, its upper end being arranged for removable connection with a service-pipe 9 provided with a valvevlO. Numeral 11 invdicates'an overflow spout for the receptacle.

Numeral 12 indicates a curved deiiectingplate which projectsdownwardly from the top of the receptacle and terminating adjacent to the lower end of the supply-pipe 8,

said plate being secured atV its ends to the opposed sides of the receptacle.

I provide a holder or cage now to be de# scribed for containing the photographers prints, said holder consisting, in part, of an axle 13 provided with an enlarged part or cylinder 14, said axle being journalled in a pair of bearings-blocks 15 which are secured to the sides of the receptacle 4.

Numerals 16 indicate numerous U-shaped holder-bars disposed radially of and having their ends mounted in the cylindrical body. At 17are indicated a group of U- shaped holder-bars pivotally mounted at their ends in the cylindrical body 14, and at 18 are indicated a second` group offU-shaped holder-bars which are also pivotally mount ed at their ends in said body 14.

I provide a pair of flexible strands or chains 19 for connecting the U-shaped bars 16 with each other. Also I provide a pair of flexible strands or" chains 20 for connecting the U-shaped holder-bars 17 with each other and with a bar 16, and at 21 are indicated a pair of'chains which connect the U-shaped bars 18 with'each other and with one of the bars 16.

The U-shaped bars maybe constructed of wire to advantage. Accordingto the construction described theV bars 16 will be disposed radially anduniformly, spaced apart, and on account of their mounting theywill remain rigid with the cylindrical body 14 and axle, and` if the axle isrotated the bars 16 will be moved thereby.l

Itwll be'SeIl that the l1-Shaped bars 17 are connected to form a group or section, and may be swung on their pivotal mounting. Also the U-shaped bars 18 which are connected one with the other may have swinging movements.

Numerals 22 indicate a pair of springs which operate to cause the groups of bars 17 and '.18 to move toward each other, and in operation when it is desired to place the photographic prints in the cage or holder mentioned, the springs, are detached from the bar of one of the sections 17 or 18. The bars of these sections 17 and 18 are then swung downwardly to provide an adequate opening between said sections. The prints are then placed in the cage through said opening. f

The holder- bars 17 and 18 .of said sections are then swung upwardly and the springs 22 are then placed in position to connect the parts as shown in Figs. 1 and 3 .of the drawing, water is then permitted to flow into the receptacle through the curved supply-pipe 8, the result being that the cage will rotate in the direction indicated by the arrow shown in Fig. l. The receptacle will be filled with water which will be'discharged yfrom the spout 11. The prints will be moved in the cage without injury and without any attention of an operator, the acid being removed from the prints, and fresh water being supplied for thoroughly cleansing the prints. y

The U-shaped holderbars may be connect- I ed at their s-ides by flexible strands 23 to conline the prints within the cage. However Y this is not an important feature. Numerals 2d indicate flexible strands for connecting the U-shaped bars at the periphery of the circular cage. Since small sized prints might move outwardly of the cage these strands 23 and 24 are of advantage.

By referring tovFig, 1 of the drawing it will. be seen that the deflecting-plate 12 has a curvature corresponding approximately to the curvature of that end of the receptacle remote therefrom. Also the distance between the periphery of the cage and. dellecting-plate is approximately equal to the distance between the periphery of the cage and that end of the receptacle. remote from said deflectingplate, these features being vof advantage so that the cage will rotate by a limited force of Yflowing water.

It will be understood that .any source of supply of clean water will be suitable if it is moved by pressure, as by a. water-works system, or if moved by force of gravity. On account of the particular arrangement of parts a very limited QrCe of moving Water will Cause rotation of the cage and its contents.

It will be vullderstoed that the receptacle is not permanently connected to the service pipe. The upper end ofthe intake pipe 8 is disposed in ornmunication with the service pipe 9, but may be removed therefrom, and this is a desired feature to permit the receptacle to be inverted for removal of the water therein whenever required.

It will be noted that an unobstructed passageway for water is provided between the U-.shaped holder-bars of the print-holder and the walls of the receptacle, and since the print-holder is circular in side elevation it will rotate readily by the movement of water under pressure delivered from the servicepipe, said receptacle being approximately of semicircular form in side elevation so that the water may move freely for rotating said print-holder.
