2Claims.

This invention relates to washing machines for glassware, tumblers, beer glasses, and like receptacles, in which the receptacle is applied, by hand to fountain brushes and the flow of the cleansing fluid is controlled by the application of the glass to the washing or cleansing devices.

The present application is a substitute for the application filed by me on the 27th day of June, 1938, under Serial Number 215,965.

The invention involves the use of a liquid detergent, sterilizer, or antiseptic, that is mixed with either not or cold water, under pressure, and means are provided for spraying both the interior and exterior surfaces of the glass, simultaneously, with the mixture or cleansing solution. Internal and external brushes are employed in connection with the cleansing liquid or mixture, and the brushing action is secured by twisting the wrist of the hand which grasps the receptacle to be washed.

Means are also provided whereby the washed receptacle is finally rinsed by the use of clear water, and the rinsing is accomplished while the receptacle still'remains immersed in the fountain portion of the washing machine. The receptacle is thus sterilized, washed, and rinsed in successive steps in a single manually controlled operation, by immersion or submersion of the receptacle within the spray or fountain portion of the washing machine.

- The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more specifically set forth and claimed. In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention in which the parts are combined and arranged according to one mode I have thus far devised for the practical application of the principles of my invention, but it will be understood that changes and alterations may be made in these exemplifying structures, within the scope of my appended claims, without departing from the principles of the invention.

- In the preferred form of my invention as illustrated in the drawings I utilize a housing I of suitable size and shape, which is provided with 2J0 a cover or closure 2 secured thereon in suitable manner. Within the housing are formed an elevated liquid detergent chamber 3 having an upper screw plug 3 and a bottom wall 4, and the housing is also formed with a cylindrical washing or brushing chamber 5 having an elevated bottom 6.

The detergent reservoir 3 is provided with a vent opening V in its top wall formed by the closure 2 of the housing, and the washing or brushing chamber has a round opening in its top wall, also formed by the closure 2, and this opening is provided with a rubber ring or gasket of .suitable material 1, of sumcient size to readily permit insertion of the glass Q into the washing chamber. The glass Q is grasped by the fingers and thumb in well known manner, inserted through the rubber ring, held by the fingers and thumb while being washed and rinsed, and then withdrawn. While the glass is immersed or submerged in the fountain sprays, it is given several turns by twisting the wrist, in order that all parts metrically disposed brushes extending vertically within the chamber. In close proximity to these brushes T the chamber wall is provided with four vertical series of spraying ports 8 extending laterally of the wall; so that the brushes are supplied with the cleansing solution, or with clear rinsing water, as desired. These ports communicate with vertical duets or upright passages 9 in the wall of For cleansing and rinsing the interior surface oi the immersed glass, I provide a central fixed, tubular post l2 having a base 13 that is fixed in suitable manner to the bottom of the washing chamber, above the distributing chamber, and

the interior of this tubular post is open to the distributing chamber II for flow of cleansing solution or for flow of clear water. The tubular post is fashioned with numerous lateral ports l4, and the exterior of the post is covered with tufts H to form a stationary brush conforming to the interior of the glass Q.

As indicated in Figures 1, '7, and 8 the exterior brushes T and the interior brush l5 are closely related in order that the glass may be pushed down into the washing chamber; the depending rim or edge of the glass, as it is pushed down, separating the four exterior, brushes from the single interior brush; and when the glass has reached its fully depressed position, the inner and outer brushes are in frictional contact with the wall of the glass.

The flow of washing solution is automatically controlled through the use of the glass as it is manually submerged or depressed within the washer, and for this purpose I employ a depressible, spring-lifted stem 16, located and supported within the tubular post, with its upper free end projecting above the stationary brush IS. The free end of the stem is capped with a rubber or resilient pad I! against which the inner face of the bottom of the glass contacts when the glass is inserted in the washer, and by action of this contact the spring lifted stem is depressed. when the cleansed and rinsed glass is withdrawn from the washer, the spring-returned stem is automatically lifted to its initial position as indicated in Figure 1.

The lower end of the stem passes through a hollow head or valve casing l8 that is attached at the undersideof the bottom 6 of the washer chamber, and the interior of this valve casing communicates with the distributing chamber l I heretofore described.

0n the depressible stem and within the valve casing is mounted a solid cylindrical piston valve l9, which, as best seen in Figure 4, has a longitudinally extending port I9 opening above and below the piston, and the upper end of this port is provided with a flexible disk, or flap-valve l9a that is attached to the stem and is adapted to close the port I! on the upstroke of the stem and open the port on the downstroke of the stem. This auxiliary valve is adapted to control the flow of a charge of the liquid detergent, sterilizer, or antiseptic, which charge is admitted to the valve casing by the piston valve, and then lifted to the distributing chamber, as will be described.

The depressible valve stem is pushed down against the tension of a spring that is coiled about the lower end of the stem and interposed between a cap 2| fixed on the extremity of the stem and a stationary base plate 22 that is supported from and below the valve casing, as by screws.

The supply of water, either hot or cold, under pressure, is furnished to the washer through the supply pipe 23. which opens into the interior of the valve casing just above the piston valve, when the latter is in its depressed or open position, as indicated in Figure 4.

The detergent reservoir 3 may be filled, when the screw plug 3' is removed, by pouring the liquid in through the top filling hole, and the liquid detergent is suppliedby gravity from the bottom of the reservoir through the feed pipe 24. which communicates with the interior of the valve casing just below the piston valve when the latter is in closed position, or uplifted, as shown in Figures 1 and 2.

An outlet or drain for the washing chamber is provided by the drain pipe 25, which as indicated in Figure 9 opens down through the bottom wall of the washing chamber.

An exterior gage 26, as best seen in Figure 1 is provided to indicate a low level of the liquid detergent in the reservoir 3.

As indicated in Figure 2 it will be apparent that while the piston valve is in uplifted position a charge of liquid detergent under gravity flow from the reservoir fills the valve casing below the piston valve, and this charge is lifted or pumped up into the distributing chamber, through the upper end of the valve chamber, as the piston valve is depressed. As indicated in Figures 3 and 4, the supply of liquid'detergent is cut off by the descending piston valve, and it remains cut of! while the piston valve is in lowered or open position.

In Figures 2 and 3 the water supply to the interior of the valve casing is closed, and this supply is not opened until the piston valve reaches its lowermost or depressed position in Figur 4, and after the charge of liquid detergent has been pumped into the upperpart of the valve casing or into the distributing chamber H.

With the piston valve in lowered or open position, the water, under pressure flows through pipe 23 into the casing and into the distributing chamber I l, thence through the tubular post and its ports, and also through the radial ducts III to the ports of the brushes T, carrying with it the liquid detergent in solution.

Under these described conditions, the flap valve l9ais held down or closed on port I 9' by the water under pressure, and the supply of detergent remains cut off. Eventually the cleansing mixture is consumed in spray in connection with the two brushes, or the single inner brush and the set of outer brushes, and then, with the piston valve still open or depressed, clear rinsing water flows from the supply pipe 23 to the numerous spraying ports 8 and H of the brushes.

As the rinsed glass is withdrawn from the brushes, and from .the valve-stem, the latter is spring returned or lifted, moving the piston valve to closed position, and also closing, or holding closed the flap valve l9a, thereby shutting off both the water supply and the supply of liquid detergent from the distributing chamber,

After the glass has been withdrawn from the washing machine it may be dried in any suitable manner.

I claim:

1. In a glass washing machine having a distributing chamber, the combination with a valve casing communicating with said chamber and having an inlet port, and a tubular ported post mounted above the casing, of a spring-lifted depressible stem mounted in the post and projectdetergent inlet port, ofa spring-lifted depressible stem passing through said chamber and casing, a piston-valve on the stem for controlling said ports, sald piston-valve having a port extending longitudinally. therethrough, and an automatic valve mountedi on the piston valve adapted to open the last mentioned valve to permit flow of acharge offthexdetergent to the distributing chamber ss-tne -piston-valve-stem is 10 depressed to open the water] inlet port.
