Other objects and advantages of the invention will become apparent during the course of the following description forming a part of this specification and in which taken with the drawing,

Mountedion one of the side walls aof thecasing i. 51'is: an overflow-pipe I 2 having: therupperrend els -i10 at l3 bent angularly and 'projectings throughixan i opening5formed inxthe casing.;whereby antoutlet nozzle 1 4may be secured thereto as clearlyoshown r. Figure: 1. The outlet: nozzle I 4 is elongated andis-provided in thefront wall with a 51017- 15. 1 51* Bushings or washers l6 maybemounted on both sides of the casing walla] surroundingmthe pipe l3 and-the lowerend'of the pipe IZ-may be con-li nected to thepipe-9 asatlll by meansiofsasuitable union; 2o

Therstructure thus far described :may be -sup=1 portedupoma suitableframe l8 having isupports inglegs l Bandit will .be noted-thattheluppened e of the frame It is bent outwardly to provide a flange lying flush with the upper edge of the 25 casing 5.

Extending between the end walls 6 of the casing 5 is a spray pipe 20 having one end as at 2! connected to a bushing while the opposite end extends through the end wall 6 through suitable 30 bushings 22 and terminates on the outside of the casing wall 6 as at 23 whereby a water supply pipe may be connected thereto having the opposite end connected to a domestic water faucet. Perforations 24 are formed in the bottom of the spray pipe 20 whereby several jets of water-will be directed downwardly and toward one side wall I of the casing 5. The pipe 20 will normally lie under the water level of the receptacle 6.

Rotatably mounted within the casing 5 is a 40 metal drum 26 made entirely of screen or metal having perforations 21 formed in the periphery thereof and said drum is closed at the ends by means of end walls 28. An elongated opening is formed in the periphery of the drum 2B and is adapted to be closed by a screen frame 29 having a wire fabric 30 stretched thereover as clearly illustrated in Figure l. The screened frame 29 is hinged to the drum 26 as at 3| and is provided with fasteners 32 pivotally mounted as at 33 0 upon the drum so that a projection formed on the fastener will overlap the swinging end portion of the frame 29. The drum 2B is provided on the end wall 28 with a stub shaft 34 adapted to be received in bearings 35 secured to the end walls 6 of the casing by means of a bushing plate 36. Additional bearings 35 are provided for supporting the drum in a raised position partially out of the washing liquid.

Formed at intervals upon the periphery of the drum 26 are elongated fins or vanes 31 adapted to be presented in the path of the downwardly projected water jet from the pipe 20 through the perforations 24. It will be noted that the jet openings 24 are presented tangentially to the drum 26 so that the water will impinge the vanes or fins 31 and cause a rotation of the drum and carrying with it the contents thereof whereby all sides and portions of the photographic films will be exposed to a cleaning liquid such as water thereby saving time in the operation of washing the photographic films and photographs.

As illustrated in Figure 4, there is provided a rack which may be used in lieu of the drum 26 after the'drum has been removed from its bearings 35 Which necessitates merely the lifting of the drum therefrom providing adequate space for the photographic film rack which includes U-shaped end members 40 adapted to extend over the end walls 6 of the container 5 and said U-shaped members 40 are provided with horizontal bars 4| upon which the photographic film receiving rack may be received which includes 3 a horizontal bar 42 having the ends supported by the horizontal bars 4| and adjacent the bars 4| there arelprovided downwardly extending bars or channel-shaped frame members 43 connected at the bottom by means of a channel-shaped .5. member 44 and braced at the upper end by means of suitable brace bars 45. For aconsideration of the operation of the invention, it will be first supposed that the operator desires to wash the photographic prints 40 after they have been treated with the usual chemical. -The first step comprises inserting the photographic prints within the drum 26 by opening the wire screened frame 29 in the desired manner. Before the photographic prints have been thus placed, the water supply is turned on through the pipe 23 which causes the jets of water issuing through the perforations 24 to impinge upon the vane 31 and rotate the drum 26. After a period of time, the container 29 may be lifted vertically and supported on the bearings to remove the washed prints and replenish the Work. Water may run out of the pipe [2 to a waste pipe or sink when the level in the tank 5 exceeds the overflow pipe, l4. After the photographic films have been washed and the apparatus is out of use, the valve l0 may be turned so as to cause the contents of the receptacle 5 to drain through the pipe 5 and out of the entire receptacle.

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same and that various changes in the shape, size and arrangement of parts may. be resorted to without departing from the spirit and scope of the invention as claimed.

I claim:-

A photograph and film washingmachine comprising a receptacle, a rotary drum having .a-

perforated peripheral wall mounted within the receptacle, longitudinal vanes projecting outwardly of the peripheral wall of the drum and of the same length as the drum, an overflow pipe for the receptacle having. one end entering the side wall of the receptacle adjacent its upper end, a water inlet pipe extending longitudinally of the receptacle at the side thereof adjacent the overflow pipe with the ends supported in the walls of the receptacle and substantially in the horizontal plane of the overflow pipe to project a spray of water tangentially downwardly to the rotary perforated drum and in impelling contact with the vanes and a drain pipe atthe lower end of the receptacle.

LEO A. BONISH.
