1 Claim.

The present invention relates to new and useful improvements in washers for mugs, glasses and other receptacles for use particularly in such public places as taverns, hotels, restaurants, etc., although it will be understood, of course, that a device in accordance with the present invention may be used in any place for which it may be found adapted and desirable.

The primary object of the present invention is to provide, in a manner as hereinafter set forth, a washing device of the aforementioned character comprising a novel construction, combination and arrangement of parts, through the medium of which the inside and outside of a receptacle may be rapidly but thoroughly cleansed.

Another very important object of the invention is to provide a washing device of the aforementioned character comprising a novel construction of receptacle opened valve for automatically controlling the discharge of the washing fluid.

Still another very important object of the invention is to provide, in conjunction with a washing device of the character described, novel means for preventing what is commonly known as water hammer when the device is in use.

Other objects of the invention are to provide a receptacle washing device of the character set forth which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, sanitary. and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in front elevation of a washing device constructed in accordance with the present invention, a portion of the hammer eliminator being broken away in section.

Figure 2 is a view in vertical section through the device, taken substantially on the line 2-2 of Figure 1.

Figure 3 is a top plan view.

Figure 4 is a detail view in horizontal section, taken substantially on the line 4-4 of Figure 1.

Figure 5 is an elevational view of the upper end portion of one of the tubes provided for washing the outside of the receptacle.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a vertical nozzle which is designated generally by the refer- 'ence numeral I, said nozzle including a tube 2 having a slightly enlarged internally threaded lower end portion 3 providing an external shoulder 4. The nozzle I further includes a substantially dome-shaped removable tip 5 threaded on the upper end of the tube 2 and having discharge ports 6 therein. The nozzle I still further includes an internal shoulder l in the lower portion of the tube 2, the purpose of which will be presently set forth. The nozzle I is mounted on a water supply pipe 8 through the medium of a T 9 and a nipple II], the latter being threaded into the lower end portion 3 of the tube 2.

Radiating from the lower end portion 3 of the tube 2 are pipes II on the outer ends of which vertical tubes I2 are mounted through the medium of elbows I3. Removable caps I I are threaded on the upper ends of the tubes I2. In their upper end portions the tubes I2 are provided with discharge ports I5 which are adapted to spray water inwardly and downwardly over the bottomand sides of an inverted receptacle on the nozzle I. Mounted on the tubes I2 is a metallic shield I6 for the water, said shield being substantially C- shaped or open at its front to accommodate the handles of mugs, cups, etc., also the hand of the person using the device. A horizontal shield in the form of a disk I! rests on the pipes II and encircles the nozzle I.

The lower portion of the tube 2 of the nozzle I has formed therein a seat I8 with which a valve I9 is engageable. The valve I9 is mounted on the lower end of a stem 20 which extends slidably through the tip 5 for engagement and actuation by the receptacles to be washed. The reference numerals 2| and 22 designate upper and lower apertured guides, respectively, for the valve stem 20 in the tube 2, the former being mounted on said stem for movement therewith, the latter being stationary and resting on the shoulder 1, said stem 20 being slidably therein. A sleeve 23 is removably mounted on the stem 20 below the guide 2| and a closing spring 24 is interposed between the sleeve 23 and the lower guide 22. A pin 25 is provided for limiting upward movement of the upper guide 2| under impulsion by the spring 24. is a comparatively long, heavy cushioning spring 26 which rests on the lower guide 22, the upper end of said cushioning spring being normally spaced from the upper guide 2| for allowing sufficient independent initial movement of the stem 20 to permit the valve I9 to open.

As illustrated to advantage in Figure 1 of the drawings, a hammer eliminator designated gen- Also mounted in the tube 2 of the nozzle I erally by the reference numeral 21 is connected to the T 9 through the medium of a nipple 2B. The unit 21 includes a cylinder 29 having internally threaded end portions for the reception of. closure plugs 30. A drain cock 3| is mounted on the outer end of the unit 21.

Briefly, the operation of the device is lows:

The spring 24 normally maintains the valve ill in closed position, being assisted by the pressure of the water. The receptacle to be washed is inserted and placed over the nozzle l and sufiicient downward pressure is applied to said receptacle to open the valve 19 against the tension of the as folspring 24, the bottom of the inverted receptacle engaging the upper end of the stem 20, as will be understood. After the valve 19 opens, the cushioning spring 26 is engaged by the upper guide 2| and yieldingly resists further downward movement of the receptacle, thus preventing said receptacle from striking the upper end of the nozzle l with suificient force to be damaged thereby. When the valve l9 opens'water is discharged from the ports 6 and I5 over the entire inner and outer surfaces of said receptacle in a manner to thoroughly cleanse the same. It will be noted that the construction and arrangement is such that the entire device may be rapidly taken apart or disassembled for cleaning or repairs when desired. Air trapped in the comparatively large cylinder 29 of the unit 2'! cushions the water in a manner to prevent hammering when the valve l9 closes during the operation of the device. The cock 3| permits the cylinder 29 to be drained when necessary.

It is believed that the many advantages of 9.

washing apparatus constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A receptacle washer comprising an upstanding nozzle having ports in the upper end thereof and receivablein a receptacle, a plurality of. pipes communicating with the lower portion of said nozzle, tubes rising from said pipes in spaced relation to said nozzle and being provided with ports in the upper portion thereof, the lower portion of said nozzle being adapted to be connected to a source of liquid supply, a valve seat in the lower portion of said nozzle, a stationary valve guide in said nozzle, adjacent said valve seat, a slidable guide having a depending sleeve, a valve for contacting with the valve seat and having arod extending upwardly through the stationary guide and said sleeve of the slidable guide and projecting beyond the upper end portion of the nozzle, a coil spring disposed in said nozzle between the stationary and the slidable guide, a coil spring encircling said valve rod and disposed between the stationary guide and the lower portion of said sleeve, means connecting said valve rod to said slidable guide, a substantially O-shaped shield mounted on the tubes and a horizontal shield encircling the lower portion of the nozzle, and resting on said pipes.
