Application filed November 12, 1913. Serial No. 800,544.

To all whom it mac concern:

Be it known t at I, Josnrrr BENZION, a citizen of the United States, residing in the borough of Manhattan, New York city, county and State of New York, have invented certain new and useful Improvementsin Tumbler-lVashers, of which the following is such a full, clear, and exact de scription as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the ac companying drawings, forming part of this specification.

My invention relates to certain improve ments in machines for washing tumblers by means of jets of water, and more particularly to the type of machine in which the tumbler is held with its mouth down and is then depressed in order to turn on the Water.

One of the principal objects of my present invention is to provide a machine of this class with a combined spraying device and guard, the purpose of the guard being to prevent the water from splashing the operator.

The invention also seeks to provide a very substantial and durable spring-seated support for the vertically movable spraying device.

With these and other objects in view my invention consists in the various novel and peculiar combinations and arrangements of the several different parts of the machine, all as hereinafter fully set forth and then pointed out in the claims.

I have illustrated a type of my invention in the accompanying drawings, wherein:

Figure 1 is a vertical sectional viewof my improved tumbler-washer. Fig. 2- is a top plan view of the machine with part of the cup-shaped spraying device and guard broken away and in horizontal section. In this view a portion of the drain-pan isga lso shown as broken away. Fig.3 is an senlarged central vertical sectional view of the machine with; the upper portion of the combined sprayer and guard broken away, like Wise the portionsofthe drain-pan. Fig.- +1

is a similar view, to thatshown in Fig. 3 of the spring-seated slidingi'valve but with the valve shown in closed position. Fig. 5 is a horizontal sectional view of the n achine the plane of the section beingindicated by line 5-5 in Fig.3. Fig. 6 is a horizontal "being shown in this construction.

sectional view of the parts shown in Fig. 3, the plane of the section being indicated by line 6-6 in said figure.

Referring to the drawings in which like numbers 0 reference designate like parts throughout, 1 is the water supply pipe which is attached to a vertical tube 2, the lower end of which is provided with an external screwthread for connecting it with the water pipe. The upper end of the tube 2, is enlarged so as to provide a valve chamber 3. This tube is provided with an external flange 4, the under side of which rests upon the inner surface of the concave drain-pan 5, in the center of which is formed an opening 6,"

through which the tube 2, extends, and with which it forms a watertight joint. The upper end of the tube 2, is provided with an, external flange or lip 7, upon which rests the center part of the perforated drip-plate or tray 8, the rim or periphery of which rests upon a shoulder 9, formed near the upper edge of the concave pan 5, the upper edge of the pan being provided with a rim or gallery 10. The center of the drip-plate 8.. is formed with a perforation 11, through which extends the upper end of the tube'2. A tubular coupling 12, having its-lower end externally threaded is screwed into the interior thread on the upper end of the tube 2, and this coupling is provided with a peri'phw eral flange 13, which bears upon the upper surface of the drip-plate 8, around the open ing .11. therein and serves to clamp the dripplate 8, against the flange 7, on the tube. a soft washer 14, being interposed between the end of the tube and the flange on the coup ng- The lower end of the coupling 12 extends into the valve-chamber 3, in the tube and forms a circular valve-seat 15, for the This vertically sliding tubular valve 16. valve 16, comprises a tubular member which is closed at 17, at its lower end and is ,proiided near such end with an external iiange 16, upon Wl'HCll 1S placed a soft washer 18, which. takes against the valveseat 15. This valve is provided with a series of lateral ports 19. four of such ports These ports are arranged radially and place the exterior of the valve in communication with the hollow interior of the valve and its stem 20, the upper end of which is formed .with an external screw-thread which cooperates with an internal thread in the central perforation 21, formed in a fitting 22, which is T-shaped in cross section, and upon which is mounted the combined cup-shaped sprayer and waterguard 23, as hereinafter described.

The upper part or head of the fitting 22, is provided with oppositely arranged laterally extending ducts 24:, which register with corresponding openings 25, in the wall of the tubular valve-stem 20, and the water coming from the valve and passing into the valve-stem is supplied through the ducts 21, to the interior of the cup-shaped spraying device. At the same time the water is supplied from the upper open end of the valve-stem to the interior of the nozzle 26, which is arranged centrally within the bottom of the cup-shaped sprayer and is provided at its-upper end with spraying openings 27. This nozzle 26, has at its lower end a screw-thread which fits upon a corresponding external thread on the upper end of the tubular valve-stem 20, and the lower end of the nozzle when screwed down tight bears firmly against the interior of the bottom of the cup-shaped sprayer 23.

The downwardly projecting stem portion of the fitting 22, is tubular in shape and surrounds and makes a sliding fit with the upper and reduced end 28, of the coupling 12, and the lower end of this tubular part when in its lowest position rests against an annular shoulder 29, on the coupling, while at the same time the upper end of the coupling 29, abuts against the interior part 30, of the fitting as indicated in Fig. 3. The sliding valve and its stem, and likewise the parts connected with the stem are acted upon by the upwardly pressing coil spring 31, the lower end of which rests against an annular shoulder 32, within the tube 2, while the upper end of the spring bears against the peripheral flange 16 of the valve. Normally the spring 31, keeps the valve forced upwardly so as to close its ports 19, as shown in Fig. 4. When, however, the valve-stem is depressed by means of the connected spraying cup, the parts are moved into the positions shown in Fig. 3, and the valve-ports 19, are opened so as to-supply the sprayer and nozzle with water. The telescoping joint formed between the upper end 28, of the coupling 12, and the tubular stem of the fitting 22, provides a very substantial bearing and support for the connected parts, and as the fitting 22, may be made in a single casting, it adds to the strength of this part of the device.

The bottom and the sides of the cupshaped sprayer 23, are made hollow so as to provide a water-space 33, and all parts are in communication with the laterally eX- tending ducts 24 of the fitting 22, and this water space is closed at its upper end and at a point indicated at 34, in Fig. 1. The inner wall of the cup-shaped vessel is provided with a series of perforations 35, which are arranged at different points of the wall, as desired, and are designed to project the water inwardly against the exterior of the contained glass or tumbler 36, when the same is placed in inverted position with the lower end of the tumbler resting upon the bottom of the vessel, as indicated in Fig. 1, the position of the inverted glass being also shown in dotted lines in Fig. 3. At the same time the eX- terior of the tumbler is sprayed by the jets of water by the openings 35, in the cupshaped vessel, and the jets of water are also projected against the interior of the tumbler by means of the nozzle 26, as in dicated in Fig. 1. By having the s ray cup of greater depth than the body 0 the tumbler, as shown in the drawings, some of the spraying holes may be arranged above the level of the inserted tumbler without liability of the spray escaping from the cup.

In the construction herewith shown, the cup-shaped sprayer 33, is made of two spun metallic members, 33 and 33*, one fitting within the other, with a space between the bottoms thereof and with a very narrow space between the side walls of the two members, and as the spraying openings 35, are also comparatively small, this gives a high pressure to the water projected from the spraying openings, and this is an important feature of this particular form of cup-shaped sprayer. These two members being placed one within the other, the upper edges where they come in contact at 37 are soldered together-to form a watertight joint around the edge of the cup. The inner wall or member of the cup is formed near its upper end with an annular bend or rib 38, the under side of which is provided with a series of perforations 35, for spraying the water downwardly toward the center of the cup. The two metallic members forming the cup are secured together at their bottoms by the head or upper part of the fitting 22, these parts being brazed together, as indicated more particularly in Fig. 3, the head of the fitting extending practically across the bottom of the cup as indicated in Figs. 1 and 5. As the head of this fitting is practically a solid piece, it strengthens the cup at its central point of support. Upon the top of the fitting is formed a small boss 50, which surrounds the central perforation therein and which extends through the opening 51 formed in the bottom of the inner cup-shaped member 33", and this inner member is clamped against the upper end of the fitting by means of the lower end 52, of the nozzle 26.

A series of drip-holes 39, are formed through the double walls of the bottom of the cup-shaped vessel, and also through the interposed head part of the fitting 22, as indicated in Figs. 1 and 2, and as the fitting is brazed to the parts of the walls with which it comes in contact, the water passing 10 through the drip-holes in the cup-shaped vessel cannot find its way into these joints, and the water-space 33, is likewise cut off from communication with the drip-holes 89. The water after having been sprayed upon the tumbler passes as waste water from the bottom of the cup-shaped vessel through the drip-holes 39, and falls upon the drippan 8, and passes thence through the same into the concave pan 5, from whence: it escapes by a waste-pipe 40,

From the foregoing description, it will be readily understood that normally'the valve is closed by means of its spring as shown in Fig. 4. The operator inserts an inverted glass within the cup-shaped sprayer placing it in the position over the nozzle as indicated in Fig. 1, and as he bears down upon the tumbler, the spring 31, is compressed as shown in Figs. 1 and 3, and the water is then permittedgto pass into the valve-ports l9, and thence through the tubular Valve-stem by way of the openings 25, the-ducts 24, and the water-space 33, to the spraying openings 35, in the interior wall of the sprayer, and at the same time it is supplied to the interior of the nozzle 26 from the upper open end of the valve-stem, and the glass is thus sprayedsimultaneously npon the interior and the exterior. At the end of the sprayingoperation, the pressure upon the tumbler being released, the spring 31, forces the valve into closed position and cuts off the supply of water thereby shutting 01f the spray. In this operation, while a large number of jets may be used in the spraying device, there is no liability of any of the sprays escaping to the exterior of the vessel or of the water splashing so as to reach the outside of the vessel and splashing the operator. It will be noted that this cup-shaped vessel performs the function of a sprayer which can be made to supply a very large number of water jets, and also the function of a guard for preventing the escape of any of the spray.
