LIQUID-SERVING DEVICE.

Specification of Letters Patent.

- Patented Mar. 9, 1915..

Application filed October 27, 1913. Serial No. 797,469.

, To all whom it may concern Be it known that 1, WILLIAM P. EARN- HEART, a citizen of the United States, and a resident of Woodruif Place, Indianapolis, in

the county of Marion and State of Indiana, have invented a new and useful Improvement in Liquid-Serving Devices; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to liquid serving devices and particularly to such devices as are used on containers for serving coifee, tea, milk, cream, etc.

The object of my invention is to provide a cheap, simple and eflicient form of liquid serving device which will be adapted to be operated by one hand and which will serve liquids in predetermined, limited or continuous quantities as desired, and which will. also protect the liquid from any contamination from passing over exposed parts thus rendering the same perfectly sanitary.

My invention consists, generally stated, in the novel arrangement, construction and combination ofparts as hereinafter more specifically set forth and described and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct, use and operate my improved serving device I will describe the same more fully referring to the accompanying drawing in which Figure 1 is a side elevation of my improved liquid serving device. Fig. 2 is a like view having part of the same broken away to disclose the'interior of the same. Fig. 3

is a side elevation of the sliding stem used in my improved server. Fig. 4 is a front view ofthe lever controlling the operation of the server. Fig. 5 is a side view of the same. Figs. 6 and 7 are detail views of the plate used in connection with the controlling lever. Fig. 8 is a partial vertical view of the device showing the valve in its lowermost position. 7

Like symbols of reference herein indicate like parts in each of the figures of the draw- 1n V is illustrated in the drawing my improved liquid serving device is connected to a liquid container or tank R by any convenient means and consists of a body portion F which has a valve Q in the horizontal portion of the same for opening and shutting off the supply of fluid to the server. The

vertical portion of the body has a thread on the inside of the same at its lower end for receiving a bottom portion G to form the chamber T, and such bottom portion has its lower end terminating in a tubular portion or sleeve through which a tube C is adapted to act as later explained. Within the inter1or of the body portion F and at the top of the vertical portion thereof is a partition U which has an opening in the center of the same for receiving a tube 0 as later explained and such portion forms the chamber S above the same and the top of the chamber T. The tubes. C and C are connected by suitable means to a solid circular valve body A which has a shoulder B around the same and the tube C is provided with suitable perforations D below such valve body while the tube C has perforations D directl above said valve body, the purpose of whic 1 is explained later. Between the shoulder B. on the valve body A and the partition U a spiral spring E is located so that there is at all times a tendency to keep the said valve body at the bottom of the chamber T. The valve body A is provided with a seat X at its upper end and Y at its lower end for engaging with the seats V and W respectively in the partition U and bottom por-' tion G.

The lower end of the sleeve on the bottom portion G is threaded in order to receive a metal cap H and enough space is left between the end of the sleeve and the cap to provide a stufling box I so that there will be no leakage of the liquid between the same and the tube C.

The bottom of the tube C is provided with 'on a lever K and said plate and lever are securedin place on the cap H by means of a screw L.

The use and operation of my improved serving device is as follows The valve Q in the horizontal portion of-the body F may be opened or closed as desired and when open the liquid in the tank R is permitted to fill the chamber S above the partition U while the tube 0' will allow the same to flow through the perforations D and fill the chamber T. Considering the lever K in a horizontal instead of a vertical position as shown in Figs. 1 and 2 and the valve body A resting by its seat Y in the seat W it is desired to, place milk, cream or other liquid in a cup or glass in a predetermined volume. The bottom portion G is adjusted in the body portion F so as to regulate the capacity of the chamber T to the amount of liquid desired in the vessel and then the vessel is placed against the cross-arm or operating bar M and pressed upward. This movement will depress the spiral spring E and the seat X on the valve body A will engage with the seat V in the partition U while the liquid in the chamber T will flow through the perforations D in the tube C and through the open end N of such tube into the vessel. As soon as the vessel is withdrawn from the operating bar M the spiral spring E will immediately return the tubes C and C to their initial position. While the vessel is being filled no liquid will enter the chamber T from the chamber S as the perforations D in the tube C will be entirely above the partition U so that the two chambers will be sealed tightly against the flow of liquid from one to the other. WVhen the spring E has returned the tubes C and C to thir initial position the liquid from the-chamber S will pass through the end of the tube C and through the perforations D into the chamber T and will be prevented from leaving saidlatter chamber by reason of the perforations D in the tube G being below the level of the bottom of such chamber and in the sleeve of the bottom portion G.

\Vhen it is desired to fill the vessel such as a cup or glasswith liquid from the tank R by a continuous flow, the lever K which is in a vertical position in the drawing will be pressed to such position from its horizontal position as just explained so that the center recess 0 in said lever will engage with the raised portion P in the plate J to hold the same in position. The cup or.

glass is now placed against the operating bar M as described and pressed upward until the said bar strikes against the lever K at which point the parts are in a position such as shown in Fig. 2. The perforations D in the tube C'being partially above and partially below the partition U permit the fluid to flow freely from the chamber S to the chamber T While the perforations D in the tube 0 being above the bottom of the chamber T the liquid will flow freely from said chamber and through said perforations and the end N of the tube 0 into the vessel.

It will thus be seen that my improved serving device can be used for serving liquids in predetermined, limited or continuous quantities and the whole will be operated with one hand thus eliminating the point of economy it is perfect as there is no drippage.

It will readily be observed that no person or foreign substance comes in contactwith the liquid while serving and theliquid is deli ered from a tube instead of over or around a metal stem so that no flies or floating substance in the air infest that part and leave infection to be Washed away with the liquid at the next serving. These points insure a perfectly sanitary server.

By closing the valve Q the serving device can be readily cut out ofoperation, disconnected and the parts cleaned or repaired without emptying the tank and without the loss of any liquid.

Various modifications and changes in the design, operation and application of my improved serving device may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.
