SPECIFICATION forming part of Letters Patent No. 289,737, dated Decemberl, 1882, Application filed April 14, 1883. (No model.)

To aZl whom, it may concern.-

Be it known that I, JOHN T. WHITTLE, of Baltim e city and State of Maryland, have invente a new and useful Improvement in Tumbler-Washers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which-\ Figure 1 is a vertical central section, showing the positionof the tumbler in dotted lines. Fig. 2 is a side elevation, showing the tumbler off and the discharge taking place through pipe 0,- and Fig. 3 is a horizontal section throughthe chamber 13.

My invention relates to that form of tumbler-washer used by druggists for soda-water fountains, and at drinking-bars, and other like places, in which the tumblers are placed upside down upon a rotary support which is depressed by the weight of the tumbler and made to open a valve which allows jets of water to play upon the inside of the tumbler to cleanse it, the valve being automatically closed when the weight of the tumbler is removed.

It has been customary to provide a series of these washers connected with the same main supply-pipe, and when a number of tumblers were being washed and one was removed the closure of the valve involved an increased pressure on the valves of the others, that interfered with. the action of the others and sometimes closed them prematurely.

The object of my invention is to provide such a construction of washer as shall avoid such interference, and shall also permit the tumblers to rotate more freely without the clogging of the rotary support and facilitate the cleaning of the same, as will be fully de scribed hereinafter.

In the drawings, A represents the lower part of the case of one of the washers, which section of case connects with one of the branch pipes of the main supply-pipe. In the bulb or enlarged portion of this part of the case is arranged a valve-seat, a, which is formed in a cross bar or support, I), and which valveseat forms the upper opening of a ve'nt-tube, c, that passes from the concentric valve-seat to the exterior of the case.

On top of the section Aof the case is screwed there playsa valve-stem, 0, bearing on its lower end a valve, D, that closes over a seat, h, surrounding the orifices e, and the lower portion, z, of which valve is round or conical and adapted to fit the subjacent valve-seat a at the top of the vent-tube c. This valve is normally drawn up, so as to cover and close the orifices e and open the vent-tube a, and this position is maintained by the tension of a spiral spring, j, wound around the projecting upper end of the valve-stem, and the pressure of which spring is regulated by a screw-nut, k, against which the upper end of the spring bears.

E is the revolving turn-table or rotary support for the tumbler, which is pivoted upon the projecting end of the valve-stem. Heretofore the rotary support has been made with the stem, so as to turn with it, and this involved the friction of the stem, preventing sensitiveness of action, making the joint liable to become clogged, so that it could not turn, and involving great difficulty in cleaning out such accumulatiou' By placing the rotary support on the top of the valve-stem, so as to turn on the latter, these difficulties are entirely avoided, the turning of the tumbler is sensitively effected, and the said support can be readily taken off and cleaned.

The operation of my device is as follows: Assuming that all of the washers are provided with tumblers and the valves D depressed by the weight of the tumblers, as in Fig. 1, the vent-tube will be closed by the conical end t of valve D and the orifices 6 will be opened, and water will then pass around the cross-bar b and venttube a, and, entering the holes 6,-

will pass to the annular chamber of the upper part of the case, and thence issues through the jet-orifices f against the inside of the tumblers, and as the jet-orifices are arranged in clinedly, so as to throw the jets obliquely against the sides of the tumblers, the latter are free to respond on their sensitive rotary supports and rotate therewith. Now, if one or more of the tumblers be removed for use, as in Fig. 2, the rotary support of that washer being relieved of the weight of the tumbler,

. then, instead of being out off, is simply diverted from the orifices e to the vent-tube, and the result is that although the jets from orificesf cease to play a uniform flow of water continues, and there is no increased pressure brought upon the other tumbler-washers to produce objectionable results, as would be the case if the water were cut off absolutely.

I am aware that a single automatic reliefvalve has been provided for a series of tumbler-washers which opened when the pressure exceeded a given limit, and I do not claim such arrangement.

Having thus described my invention, what I claim as new is 1. A tumbler-washer having a feed-opening for the jets and a vent or discharge opening, combined with a valve operating alternately to open the one and close the other, substantially as described.

2. The case-section A, with discharge-tube having a concentric valve-seat, combined with the case-section B 13, having feed-openings e and f, and the valve-stem O, with valve D, acting alternately to close the feed-openings and open the discharge, substantially as described.

3. The combination, with the case of atumbler washer and a valve stem projecting through and above it, of a detachable turntable or rotary support pivoted or mounted to turn upon the external end of said stein, as and for the purpose described.
