No. 79 7,4711.A

Specification of Letters Patent.

Patented ug. 15, 1905.

Application filed January 1, 1905. Serial No. 239,625.

To {IJ/, whe/it it 1n/ray concern:

Be it known that 1', L non L. Tirrimcrrr, a citizen of the United States, residing at 729 Kennedy street, Meadville` in the county of Crawford and State of Pennsylvania, have invented new and useful limprovements in Faucets, of which the following' is a specification.

This invention relates to valves such as are generally used in connection with an oil-receptacle and are provided with automatic means to stop the How of liquid as soon as the lamp or pail into which the faucet is discharging liquid has become filled.

The objects of the invention are to improve and simplify the construction of such devices; furthermore, to increase their efiiciency in operation and to decrease the expense attending their manufacture.

W ith the foregoing and other minor objects in view which will appear as the description proceeds the invention resides in the particular combination and arrangement of parts and in the precise details of construction hereinafter described and claimed as a practical embodiment thereof.

1n the accompanying' drawing, forming a part of this specification, the figure is a vertical section through the improved valve and the receptacle with which it is connected.

The reference-numeral 1 indicates a receptacle which is supported in any suitable manner, as by means of legs 2. Leading' from the upper portion of the tank 1 is an air-inlet pipe 3, which communicates with a valve-casing t, said valve-casing being attached to the receptacle 1 in any suitable manner, as by means of securing-flanges 5. The valve-casing 4 is formed with at apering bore in which is mounted a rotary valve-plug 6, having an operating-handle 7. '1`he inner end of the valve-plug 6 is reduced to form shoulders 8, which bear against the outside of the receptacle 1. The reduced end 9 of the valve-plug 6 extends into the receptacle and is provided with a removable collar 10. Surrounding the reduced portion 9 of the valve-plug 6 is a washer 11, against which bears one end ef a coil-spring 12, the opposite end of said coilspring bearing against the removable collar 10. r1`he coil-spring' 12 serves to hold the valve-plug 6 tightly within the bore of the faucet.

r1`he valve-casing' 11 is formed with a liquidpassage 13, which is arranged transversely with respect to the bore, said valve-casing being also formed with a transverse air-passage la.

The transverse passages 13 and 1a terminate in the same horizontal plane., so that when the pail or receptacle (indicated by the dotted lines) becomes Iilled to such an extent that the lower ends of the passages 13 and 111 are submerged in liquid the flow of liquid from the tank is automatically stopped through the inability of air to enter the passage ili.

The valve-plug 6 is formed with a longitudinally-extending liquid-passage 15, which is provided with a transverse terminal 16, adapted when the valve-plug' 6 is rotated to register with the transverse liquid-passage 13. The valve-plug 6 is also formed with a transverse air-passage 17, which is adapted when the valve-plug' is rotated to register with the transverse air-passage let.

From the foregoing description it will be apparent that when the faucet is closed the tank 1 is rendered air and liquid tight, and by a single turn of the handle 7 air is permitted to enter the upper portion of the tank 1 and liquid is permitted to flow from the lower portion thereof. By reason of the fact that the transverse liquid and air passages 13 and 14 terminate in the same horizontal plane the flow of liquid from the tank is automatieally stopped as soon as said passages become submerged, for which reason the overflowing of the vessel which is being charged from the tank 1 is prevented.

It will be apparent that by the use of the coil-spring 12, together with the tapering valve-plug 6, the valve-casing f1 is securely held in position against the receptacle 1 without the necessity of soldering the flanges 5 to the receptacle or of using rivets and the like.

r1`he improved faucet of this invention is strong, simple, durable, and inexpensive in construction, as well as thoroughly ellicient in operation.

Minor changes in the precise embodiment of invention illustrated and described may be made within the scope of the following claims without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Having thus described the invention. what is claimed as new is---- 1. The combination with a receptacle, of a valve-casing having a bore, a transverse liquid-passage and a transverse air-passage communicating with said bore, a valve-plug in said bore having a transverse air-passage and a longitudinally extending liquid passage formed with a transverse terminal adapted to register' with the transverse liquid-passage of the valve-casing, and an air-pipe connecting the valve-casing with the upper end of the receptacle.

2. The combination with a receptacle, of a valve-casing having a tapering bore, a transverse liquid-passage and a transverse air-passage communicating with the bore, a tapering valve-plug in said bore having a transverse air-passage, and a longitudinally-extending liquid-passage formed with a transverse terminal adapted to register with the transverse liquid-passage of the valve-casing, the inner end of said valve-plug being reduced and eX- tending into the receptacle, a removable eollar on the reduced end of said valve-plug, and a coil-spring surrounding the reduced end of LEON L. THEURET.
