To all whom fit may concern:

Be it known that I, DAVID CHARLES MC- CANDLESS, a citizen of the United States, residing at Boise, in the county of Ada and State of Idaho, have invented a new and useful Photographic-Print Washer, of which the following is a specication.

This invention relates to machines for washing photographie prints, and the object of the invention is toV provide a machine which will b e inexpensive to manufacture and simple in its construction, and by the use of which photographie prints may be thoroughly washed with little or no attenf tion on the part of the operator.

A further object of the invention is to provide a machine which will be free of complicated mechanism and in'which the prints may be completely immersed in the bath and kept in motion and separated by the tiow of the water which supplies the bath.

YV ith these objects, and such other incidental objects as may hereinafter appear, in view, the invention consists in certain novel features of an apparatus such as is illustrated in the accompanying drawings, all of which will be hereinafter first fully described and then more particularly pointed out in the appended claims.

In the drawings', Figure 1 is a perspective View of a print washer embodying my improvements. Fig. 2 is a bottom plan View of the same. Fig. 3 is a vertical longitudinal section thereof. Figa is a transverse vertical section. Fig. 5 is-a detail perspective view of one of the bearings for the drinn. Fig. C is a detail perspective view of the fastening for the door of the drinn.

ln carrying out my invention, l employ a tank l having a semi-circular bottom 2 provided with a base or support 3, the lower edge or bottom of'whieh is flat so that the tank may be set within a sink or tub and be supported therein without any liability tobe upset. To one side, ot' the tank l secure a supply pipe 4 adapted to be attached to a hose or other connection fit-ted to a faucet whereby water may be supplied from the water service pipes of the buildingto the said supply pipe, the lower end of which is carried transversely through the base il. as shown at 5, and provided with a series of nozzles (i disposed longitudinally of the tank and openingl into the bottom of the tank at an angle to the radius of the-same. rlhe tank is also provided on one side at its loW- andare offset fromthe tank at their upperends,

thereby providing overflow openings .10 through which the water rising through the ducts may escape. Communication between the interior of the tank and the said ducts is established through openings 11 in the sides of the tank, as clearly shown in Fig. 4, the said openings being' located below the bearings 12 which consist of groovedbrackets providedvat their upper ends with lips 18 adapted to engage the upper beaded edgev of the tank and thereby suspend the bearings, as will be readily understood on reference to Figs. t and 5. These bearings or ,brackets are preferably soldered or otheravise rigidly secured to-the tank so as t0 prevent them from shifting thereon, and their lower ends are closed, as indicated at 14, so as to provide support-s for the trunnions 15 projecting centrally from the sides 16 of a drum 17 adapted to revolve on t-he said bearings within the tank and to hold the prints to be washed.

lar material and a cylinder 18 of wire netting or other reticulated fabric secured to and extending between` the circularside plates. The side plates are provided-With perforations 1S) whereby a thorough circulation of the water is permitted and also the adhering of the prints to the side plates is prevented. The cylindrical body 18 has a door 20 which is of a similar construction to the main portion'of the body and is hinged at one side ofthe vdoor opening, asshown at 21, and is provided at its free edge with slotted keepers or latch plates 2Q adapted to engage over headed lugs or hooks Q3 projecting from the corresponding edge of the door opening whereby the door may be held elosed after the prints have been placed within the drinn. The door being constructed of retieulated fabric` will be su'i.- eientlylelastie to permit. the latch plates Q2 to be diva\\'n"over the hooks or headed lugs This drinn consists of' .circular side plates 16 of sheet metal or simi- 23, wlieeupon the tension of the. body of 4 the drum and of the doorgwill draw` the saidk platesunder the projecting portion -of the 1 ads of the said lugs so that the doorwill be firmly held in its closed position.y

The construction and arrangement of the seeral parts of my machine beingv thus made known, it is thought the operation and y l advantages of the same .will be readily unl the drum is permitted to drop or be lowered until the trunnions 15 rest on the ledges or lips 14 at the lower ends of the said brackets, whereupon the drum will be supported freely within the tank with its body disposed concentric with the cved bottom of the tank. The water is then turned onAso as to flow through the supply pipe and will emerge from the nozzles 6 with considerable force so as to strike agaihst the' drum in al plane substantially tangential thereto and flow against the curved bottom of the tank so as t-o rise therein and follow the side of the same, as indicated by the varrows in Fig. 3, the force of the water causing the drum to revolve. Asthe water rises within the tank,

it will tlow through the openings 11 into the' overflow. duets 5) and will then continue to vrise until it -reaches the water-line indicated by the dotted line Q4 in Fig.v 3, which is determined by the position of the upper i ends of the said overflow ducts and is located below the highest point of the drum, as will be readily understood. I rlhe water continui ing to flow into the tank will escape from the upper ends of the overflow ducts S) and pass into the sink or tub in which vthe tank is placed and then\pass ,otl' through the usual waste pipe connections.

It will be observed that no attention on the part of the operator is required in the washing of 'the prints, inasmuch as the prints will naturally gravitate to the bottom of the drum when placed therein and the water flowing from the nozzle 6 will consequently strike against the prints and drive them against the side of the drum so that the force .of the inflowing water will impart a rotary motion to the drum. The prints will thereupon be separated and will follow the course of the water so as to be thoroughly and rapidly washed. As the prints rise with vthe water and reach the surface of the same, they will float across the drum from the one side to the other along the water-line and will consequently be prevented from adhering to the side of the'drum to such4 an extent as will prevent the Waters-caching every point ot' their surfaces or tovhold the prints to each other, as will be understood.

The water will, of course, pass upward on the outer side plates of the drum, as will be readily understood on reference to Fi g. 4, and will flow through the perforations in the said side plates so as to carry the prints away from-'the said side plates and prevent y.the adhering of the prmts thereto. The

prints may be left in the-drum Afor any desired length of time and during that time the'operator may perform such other duties as may be required of him without any necessity of watching the progress of the washing or the condition of the prints. The drum will, by its rotation, keep the prints thoroughly agitated so that uneven washing of the prints will be avoided and will accommodate prints of any size or weight. The drum serves to hold the prints directly in the path of the flowing water and will thereby keep the prints. made on" heavy paper separated so that they will be conipletely washed, and when prints on light paper are being treated, theforce of the water will be found sutlicientto keep the prints separated and the drum may be dispensed with.

From the foregoing description, taken in connection with the accompanying drawings, t-he advanta es of the construction and of the method o operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together witlrthedeviee which 1 now consider to be the best embodiment thereof, l desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.
