To all whom it may concem:

Be it known that LJornv 'E. oom, a citizen of the United States, res: at Findlay, in the county of Hancock and tate of Ohio; have invented a new and useful Outlet-Valve for Oil-Tanks, of which the follow is-a specifi' cation. 4

The prwent invention relates to improvements in outlet valves for oil tanks, or for tank cars of other types, wherein it is desirable to dispose the valve the tank to drain the contents thereof, one ob ect of the invention. being the provision of a simple on of valve, the casing of which is adapted to be threaded from above mto the upper end of the outlet pipe of the tank and carry a frusto-coniwl valve member resiliently held seated in place, the upper aid of the casing being open for ready access to the valve While the sides of the casing are provided with diametrically ports for registration with the diametrically disposed ports of the hollow valve, which is opened through the lower end for directing the fluid into the outlet P?- p A. fin-thaobject of the present invention, is the provision of a valve of this character, which is simple, inexpensive and durable in construction and which is therefore thoro y practical and useful.

1th the foregoing and other objects in view which will appear as the description proceeds, the invention residm in the combination and arrangement of parts and in the details of construction hereinafter dem'bcd and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without deErting from the spirit of the invention.

the drawings-Figure 1 is a vertical central sectional view through the lower portion of an oil tank and the upper portion of an outlet pipe thereof, with the present valve in operable relation thereto, the said valve shown in section. Fig. 2 is a side elevation of the complete valve and valve casinggperse. Fig. 3 is a top plan view thereof.

to the drawings, the numeral 1 designates the tank which is provided with the outlet pipe 2, the upper end of which is provided with the interiorly screw threaded portion 3 for the reception of the exterior threads 4 of the lower tapered end of the valve casing 5. The valve casing 5 is dis posed to'fit within the tank in a vertical position and is provided with diametrically disposed ports 6, the lower edge of each of which is adjacent to the lower edge or bottom line of the tank. Mounted within the casing is the hollow frusto-coniml valve 7, which is provided with the two ports 8 diametrically disposedth thin the walls:E thlpreof for registrationwi eportsGoteca' 5, so that the liquid within the tank mai' directed through said ports and downwardly through the open end of the valve 7 and the easing into the outlet pipe The upper end of the valve 7 is closed, and is provided with the concentrically disposed stem 9 which is provided with the centrally disposed angular or square socket 10, the purpose of which will presently appear. Surrounding the stem 9 and exerting a presm-e downwardly to hold the valve 7 seated properly the tapered portion of the casing 5. is a spring 11, the upper end of which is held in proper position by means of the bridging plate 12, whose terminals are clamped to the lugs 14 of the casing 5 as illustrated.

The bridging member 12 is provided with a circular opening 13, for the reception of the operating stem 15, which is provided with a squared end for the gement with the opening or socket 10 of the stem 9 at one end, and with the handle 16 at the oppos'te end, said stem 1-5 being extended upwardly through the tank intenorly thereof, a) that the handle 16 may be operated to open and close the valve 7.

From the foregoing description, it is evident that with the present construction of the valve, the member 5 is merely to be oscillated or rotated one-quarter revolution to place the ports thereof in regiqration with the ports of the casing. and that the liquid is directed through the ports in teriorly of the galve ant} valve easing into the upper end 0 the out et pipe. t e u r end of the valve being sealed, so that e will hold the same downwardly and thus prevent the leakage of the fluid or liquid through the upper open end of the valve easing into the outlet pipe 2.

By this construction of valvethe member 5 is rotated in the same plane and the amount of fluid is regulated entirely by the codperation of the ports of the casing and vale requiring merely a quarter turn to place the ports in full registmtion or out of registration.

It is also apparent that by reason of the bridging};} member 12 and its proper connection wi the casing, that the spring 11 will be held in place to exert the proper pres sure to maintain the haste-conical valve member 7 properly seated in a tight condition and vet so that the same may be pr0perly oscillated.

By threading the upper inlet end of the outlet pipe 2, the present valve may be properly asembled before introduction therein as it is merely necessary to utilize the lugs H to rotate the casing to cause the threaded portions 3 and 4 to properly engage.

What is claimed is:

1. The combination with a liquid tank, and an ouflet pipe therefor having an interiorly threaded portion of slightly greater diameter than the inlet of the pipe, of a valve for controlling the pipe. including a casing having a frusto eonical lower end, said end being exterior-l3 threaded for engagement with the threads of the outlet pipe, a frnsto-conical valve having a socket formed therein from the lower reduced end thereof and provided with diametriwlly disposed ports. said casing in the conical rtion thereof being provided with diametrically disposed ports for regifiration with the ports of the valve, a stem carried by the frusto-conical valve and extending in an opposite direction to the socket thereof,

a spring surrounding said stem, a bridging member conneded across the valve casing andexerfingapressnreupon thespringto hold the valve seated withm the msmg, and means for operating the valve extending through the bridging member and engaging the fiem.

The combination with a liquid tank, and an outlet pipe therefor having an interiorly threaded portion of slightly greater diameter than the inlet of the pi of a valve for controlling the pipe, uding a casing having a frusto-eonical lower end, said end being exterior-1y threaded for engagement with the threads of the outlet pipe, 2 frusto-conieal valve ha a socket formed therein from the lower need end thereof and provided with diametrically disposed ports, said casing in the frusto-oonical portion thereof being rovided with diametrically disposed aErr-ts or registration withtheportsofthev e,astemearriedby the frusto-conical valve and extending in an opposite direction to the socket thereof, a spring surrounding said stem, a bridging member1 oonnectedacross the tialve casing an exerting a pressure 11 n e to hold the valve seated the eau l the said stem being provided with an angular socket in the upper end thereof and said bridging member being provided with a circular opening concentric to the socket, and an operating stem having an end seatable within the angular socket of the valve stem and extending through the drenlar opening of the bridge, whereby the valve may be oscillated In testimony that I claim the foregoing asmy owmlhaveheretoafixedmyslgna ture in the presence of two J OHN E.
