COFFEE URN FAUCET Filed Feb. 2, 1929 Patented Dec. 22, 1931 PATENT? OFFICE HENRY D. KELLY, OF KANSAS CITY, MISSOURI COFFEE URN FAUCE'J.

Application filed February 2, 1928. Serial No. 337,082.

valve construction in which the seat and valve necessarily conform exactly to each other re- 5, gardless of the length of service of each, so that should the valve, for example, be lost or damaged from any cause, it can be replaced by another which will fit the seat with perfect accuracy. Another object is to provide a fau- 10 cet having a by-pass to the spout, and thus guard against the escape or leakage of beverage from the front endof the faucet or any other point than the spout itself, a still further object being to provide a vent for effect- 1 ing theimmediate discharge to the spout of any beverage which may pass the latter while the valve is unseated.

With these objects in view, the invention consists in certain novel, and useful features 20 of construction and combinations of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawings, in which:

Figure 1 is a view of a faucet embodying the invention, partly in side elevation and partly in central longitudinal section.

Figure 2 is across section on the line II-II of Figure 1.

Figure 3 is a detail perspective view of the valve.

Referring to the drawings in detail, 1 indicates a faucet exteriorly threaded at its rear end at 2 for connection with the coffee urn, not shown. It is also provided with a coupling connection 3 for a coffee gage column, not shown. The bore or passage of the faucet is enlargedforward of the plane of the coupling connection 3 and at the point of .enlargement is formed with a conical valve seat 4;. The reduced portion 5 of the bore is controlled by a conventional rotary plug valve 6, which when closed shuts off the forward flow of beverage and opens communication norm'ally with the beverage gage so that the level of the coffee in the urn may be observed.

At the front end of the valve seat, the faucet is provided with a depending spout 7 normally closed by the cylindrical head 8 fitting snugly in the enlargement of the bore, the head having a tapered valve portion 9 for accurately fitting the seat 4. The front end of the enlargement of the bore is internally threaded at 10 and is closed by a threaded ,55 cap llhaving a centralperforation 12 snugly receiving the forwardly-projecting stem 13 of the valve, and a coiled spring 14 fits around the stem and into and against the cap and valve head for normally holding the .60 valve tightly upon its seat. Forward of the cap, the stem has a vertical slot or opening 15 for receivin an upright lever 16 pivoted at its lower en to and between a pair of forwardly-projecting lugs 17 of the faucet, and

said lever is provided with a handle 18 which when swung forward applies pressure on the stem to unseat the valve, the spring returning the valve and lever to their original positions when free to do so. 70

When it is desired to hold the valve unseated for effecting the discharge of all or a large quantity of the beverage, a plate 19 pivoted at 20 to a lug or lugs projecting upward from the faucet, is swung forward into the path of rearward movement of the lever, as piartially indicated in dotted lines in Figure When the valve is unseated, and the lug valve 6 is open, the beverage can pass r0m, it through the valve seat opening to the spout, and in the event a small quantity passes for- 'ward of the spout into the enlargement of I the bore of the faucet forward of the head of the valve, it will pass downward from said enlargement through the by-pass or drain passage 21 to the spout, this action being made practically instantaneous by providing the cap with a vent hole 22 for the admission of air to said enlargement of the bore.

It will be apparent from the foregoing that the ground and finished valve and valve seat, conforming exactly to each other, establish. a perfect liquid-tight joint, and that the wear on each will be at a corresponding angle and 9 hence maintain a liquid-tight relationship regardless of length of service, and that the original valve can be replaced at any time by a new one of identical type which will fit the seat as accurately. It will also be apparent that by the provision of the by-pass, it will be impossible for the beverage to escape through or around the cap, and that the air vent will insure the instant escape of any beverage to the spout, in the event of escape past the valve head into the enlargement of the bore of the faucet, and that for this reason there will be practically no drippage, even from the spout, after the valve is closed.

From the above description it will be apparent that the faucet may be modified in minor particulars within the principle and mode of operation involved and the spirit and scope of the appended claim.

I cla1m:

A faucet having a longitudinal bore or passage, including an intermediate conical valve seat of rearwardly-tapering form, and a depending spout communicating with the bore or passage forward of the valve seat; a centrally-perforated cap closing the front end of the bore or passage, a yieldingly-closed valve,

' comprising a cylindrical head closing the spout passage, a tapering end engaging the valve seat, and a stem extending through the perforation of the cap; and a lever on the faucet, engaging the valve stem for withdrawing the valve from its seat and opening communication between the latter and the spout; the cap having an air vent leading to the bore of the faucet forward of the valve head, and a faucet drain passage leading from the bore of the faucet forward of the valve head, to the spout.

In testimony whereof I aifix my signature.

HENRY D. KELLY.
