PHOTOGRAPHIC PRINT AND PLATE WASHER.

To all whom it may concern:

Be it known that I, ALBERT G. MCGREGOR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Photographic Print andPlate WVashers, of which the following is a specification.

My invention relates to a washer for photographic prints, plates and the like, and the object thereof is to provide a simple and efficient device of this character, capable of thoroughly and effectually washing such prints or plates.

Speaking in general terms, my washer consists of a receptacle with a series of Water supply inlets discharging water into the receptacle substantially in the plane of the bottom, of such receptacle, with the result that the prints become thoroughly washed especially as the described arrangement of inlets supplies constant streams of fresh water, and when prints are being Washed, it prevents such prints from becoming bunched together and from adhering to any part of.

the receptacle.

In the drawing Figure 1' is a perspective of my print-washer; Fig. 2 a plan view thereof; Fig. 3 a detail enlarged section on the line 3-3 of Fig. 2; Fig. 4 a section on the line 44 of Fig. 2 and Figs. 5, 6 and 7 detail sections of two modified forms of construction as regards the water supply.

Referring to the present and preferred embodiment of my invention as illustrated in Figs. 1 to 4 of the drawing, the same comprises an inner and outer receptacle, the.

former having a series of water inlets discharging water along the bottom of thereceptacle, and having aseries of water outlets at its margin discharging water into the outer receptacle from which the water finally escapesthrough a single outlet. While this receptacle may be made of any desired shape and dimensions I preferthe circular shape illustrated in the drawi describe the same without intention of limiting myself thereto.

As shown in the drawing, the inner receptacle comprises a bottom 1 and a vertical wall 2 while the outer receptaclecomprises.

an outer concentric wall 3 secured to the ex- Spee'iflcatioix of Letters fatent.

tended bottom 1 described, an annular space being thereby provided between the v two walls 2 and 3 and such walls being braced in suitable manner as by means of the braces 4. In practice and by preference the bottom 1 is formed in a series of segmental sections each made of sheet metal and adapted to 'overlap th'e same being secured together at such overlapped portions to form a closed bottom except for the water inlets or openings hereinafter mentioned. As more clearly shown in Fig. 3, the overlapped edge of each section is grooved in order to form a radial conduit-or water supply passage 5. vWhen these sections are assembled and connected together these conduits communicate at their inner ends with a central water :supply chamber 6 secured in suitable manner to said sections. Each conduit is provided with a series of water supply openings or inlets 7 for discharging the water in a direction at right angles to said'conduits which are'arranged along substantial lines radial of the receptacle, as indicated vin Figs. 1 and 2. Moreover these water inlets or openings are arranged to discharge the water all in the samedirection and substantially along thev bottom of the receptacle. These openings provided by striking up the overlapping edge of the sections orplates, although the walls of such openings may be separately formed and secured to the sections.

Any suitable numberof these conduits may be employed but I prefer to use a series of four of them, and likewise any suitable number of water inlets for discharging water into the receptacle may be employed. The bot- 'tom is provided centrally with a vertical chamber 8 which communicates atits lower end with the chamber 6 common to all of the conduits. This chamber 8 is provided at its upper end, with. a nipple 9 for connection witha hose or the like communicating with a suitable source of water supply. The ,inner receptacle is provided at its margln and at the bottom of its wall 2 with a series of outlets l0 communicating with the annular space between the two walls 2 and 3'.

from which space the water finally drains through the outlet 11.

' charged and enters the receptacle through the-inlets or openings 7. The prints or plates are placed within the inner receptacle and obviously in the path of thefresh water discharged thereinto. Owing to the current of water in the same direction and. ,from a plurality of discharge openings, the

prints are kept sufiiciently agitated and moreover are prevented from bunching together or clinging to any part of the washer with the result that the prints are thoroughly Washed. v 1

If desired the central water chamber .8 may be dispensed with and the water caused to enter the conduits at difierent points as illustrated in Figs. 5- and 6. In Fig. 5 I have shown the chamber 6 as provided with a depending nipple 6 to which the hose may be attached and in Fig. 6 I have shown such chamberfi as providedwith a substantially radial supply pipe 12 leading thereinto and extending to the outer edge of the washer where its end is upturned to serve as u a nipple or connection for the water supply pipe Particularly when no chamber 8 is used at the center of the washer, asin Figs. 5 and 6, I prefer to give the innermost nozzles or orifices a slight angularity thward the periphery in order to prevent theformation of an eddy or eddy such open center.

In Fig. 7 I have shown a modified form of construction as respects the supply conduits. If desired, these conduits may be made 'of a plurality of radial pipes 13 arranged in spider form (any desired number of pipes being used) and connected together at their center by a water supply chamberl l. These currents at pipes each have on one side a series of nozzles or orifices 15 of the same character as the orifices or openings 7 and discharge water in a plane parallel with the bottom of the receptacle. The entire spider is preferably removable from the receptacle.
