To whom it may concern Be it known that I, WASHINGTON GEORGE RoUNDs, of Woodstock, in the Province of fully pointed .out in the claims at the end of the Ontario, Canada, have invented certain new and useful Improvements in Devices for Washing Prints and the Like, of which the following, is a specification.
My invention relates to a device for washing prints and the like, and the objects of my invention are to enable photographic prints and the like to be thoroughly washed in a current of running water in such a way that the prints will never be allowed to mat together or lodigue in any part of the washing a paratus, rther objects being to give a uni orm direction to the moving current of water of such a character that the prints will not be bent unduly during their movement.
To these and other'ends theinvention consists in certain improvements and combinations of parts all aswil'l'be hereinafter more described, the novel features being specification.
r In the drawings, Figure 1 is a perspective View. of the device. Fig. 2 is a transverse sectional view through the same, the corrugations on the containing vessel being omitted for the sake of clearness. Fig. 3 is an enlarged sectional detail on the line 22,
Fig. 2. Fig. i'is an enlarged sectional detail taken horizontally through the containing vessel. Fig. 5 is a, erspective view of an alternative form of dlscharge member. Fig. 6 is a'section through an alternative form of the invention.
In the drawings, like letters of reference indicate corresponding parts in each figure? Referring to the-drawings, A represents the liquid containing vessel preferably in the form of a bowl, which may be provided with notches 10 around he upper ed e to permit the uniform overflow of hquid t erefrom. 1
In accordance with the present invention, the containing vessel is formed at the center with a vconoidal member 20, over which the incoming jets of liquid are discharged.
This member, in the embodiment illustrated,
in Figs. 1 to 5, is formed integral with the the, prints are washed, and to maintain a bowl, and it will be seen that in combination with the bowl, it forms an annular water circulating chamber, substantially circular in cross-section. It is within this chamber that when they are against the side an constant and uniform circulation through every part of the chamber, a plurality of jets of liquid are discharged downwardly over t he conoidal member. embodiment illustrated, Iaprovide a discharging member Bin the form of a cap, fitting over the top of the conoidal member, and provided on the interior with a series of corrugations 11 adapted to divide the discharging liquid into a plurality offine jets. To give uniformity to the discharge by presenting a smoother surface than that of the vessel A, which will often be formed of stoneware, I-prefer to provide a cap 12 on the top of the conoidal member retained in position by "a suitable bolt 13 extending through the conoidal member. The diameter of this cap 12 is such as to make it fit closely within the discharge member B, touching the corrugations thereon.
The washing liquid is supplied to the dis- To do this, in the charge member through a suitable inlet pipe conoidal member, will form a circular current in .a radial direction, and to assist the formation of this current, and to prevent the prints adhering to the sides of the vessel,- it is desirable to provide the interior of the vessel with a series of corrugations 16 'n the same direction as that in which the currents are to be formed. These corrugations thus erform two functions namely, that .of orming arough surface to which the prints will not adhere and that of guiding the movpermit the water to pass behind the thus prevent them sticking to the side.
It is desirable to provide means to prevent Y the prints'adhering to the sides of the central discharge members, and in the embodiment shown in Figs. 1 to 4:, I employ a conical flange 17 to accomplish this, while in the form shown inrFig. v5, the discharge member B has a series of perforations 18 extending around the same near the bottom, through which small jets of water will pass, effectually clearing the surface of the memad-here thereto.
Wcurrents of liquid. The corrugations rints .ber from any prints which would tend to In the form shown in Fig. 1, the conoidal member is formed separately from the containing vessel 21, and this has the advantage that the conoidal member may be used with difierent forms of vessels, which the user of the device will have on hand, and it widely difi'erent embodiments of the invention, within the scope of the claims, could be made, without departing, f om the spirit or scope thereof, it is intended that all matter contained in the accompanying specifica- .illustrative and not in alimiting tions and drawings shall be intelgpgeted as se se. What I claim as my invention 1s 1. In a print washer, the combination with 1 .baflie member adapted to be'sub merged in a fluid-containing vessel with itsv a conoida larger end lowermost to prevent wardly and inwardly curved walls, of a li uid discharge member connected at the smaller end of the baflle member to direct a stream downwardly alpng the diverging walls of the latter.

3. A device for washing prints and the like, including a vessel having a central .baflle member, and an interiorly corru ateddischarge member fitting over said aflie supply cap fitting over the end of the central member. 1
4. A device for washing prints and the like, including a vessel, a central baflie member, a discharge member fitting over the same having a conical flange on the edge adapted to prevent prints adhering to the outer surface thereof, the said dischar e members bein adapted to discharge liqu d around the bat e member.
5,. A device for washing prints and the like, including a 'bowl, having a central oowith a liquid container having wardly alon one wall. of the chamber, the point of disc arge being below the overflow level of the'chamber and an inclined guard flange on one of said parts extending from the point .of discharge outwardly and upwardly to the overflow level of the chamber for the purposes described.
7. In a print washer, the combination with a liquid container, of an upwardly project ing member centrally arranged therein forming an annular chamber within the receptacle, and means for producing circular currents in the chamber traveling vertically and radially of the central memberembodyin a. liquid discharge device arranged to ischarge in a vertical direction along one wall of the chamber.
8.
