0. A. SMITH ET AL DRAIN COCK Filed y '19. 1921 33 9 i h eiv attozuea' erheai Patented Aug. 28, 1923.

NITED OSCAR A. SMITH ALBERT J. WEATHERHEAD, JR., 0] CLEVELAND, OHIO.

Application filed May 19, .1921. -Serial No. 470,921.

To all whom it may concern Be it known that-we, OsoAR A. SMITH and ALBERT J. WEATHERHEAD, J r., citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain newand useful Improvements in Drain Cocksfof which the following is a specification.

This invention relates to drain cocks, prefera'bly adapted to be used with radiators or engines of automobiles, an object thereof being to provide an improved drain cock having a valve openable in a direction opposite to the direction of flow of the fluid from the radiator or carburetor, the construction being such that accumulations such as sediment or impurities will not pass into a drain chamber and choke the same, and such accumulation or sediment caked around 'the top of the valve will be readily broken away or dislodged upon shifting the valve upwardly to open the same.

A further object of this invention is to provide a drain cock embodying certain improvements over Patent #1345932 for drain cocks, dated June 29, 1920, and which can be manufactured readily at a minimum of expense, will be simple in construction, and efi'ective and durable in use.

Other objects of this invention will appear in the following description thereof reference being had to the accompanying drawing forming a part of the specification wherein like reference characters indicate corresponding parts in the several views and wherein Fig. 1 is a side view partly in section, illustrating the drain cook closed; Fig. 2 is a similar view illustrating the drain cock open; Fig. 3 is a perspective view of our improved drain cock, parts being broken away; Fig. 4 is a side'sectional view of another embodiment of our invention; and Fi 5 is a perspective view thereof.

Tn its preferred form herein shown and described our improved drain cock, although preferably constructed for use with radiators of automobiles or tractors, is of course adapted to be used for various other purposes such as with internal combustion en gines, carburetors, or the like. Th1s improved drain cock in the present instance, as illustrated, comprises a body member 2 threaded at one end 3 to preferably permlt the same to be secured to the bottom of a radiator or other fluid carrying receptacle,

illustrated in part at 4, designed to permit the reception of sediment or other accumulations. Although inthe present case we have illustrated our improved structure as adapted to be threaded into the bottom of a radiator, it is of course understood that we do not limit ourselves to such use but it will be readily seen that the threaded portion 3 of the body member 2 will be secured in any manner depending upon the particular structure with which our invention is used. The body member 2 is provided intermediate its length with a wrench receiving portion 5, I

and at the end opposite to the threaded portion 3, with a threaded portion 6 preferably provided with exterior threads. The body.2 is also drilled to form an axial passageway? therethrough and terminates at one end, in-

the present instance, the upper end, in a valve seat 8 preferably straight walled, Figs.

2 and 4. The same may be tapered at '8' if desired. p

The valve in this device comprises a head 9 provided with a tapered face cooperating with the valve seat 8 and an elongated stem 10 formed integrally therewith. This stem is adapted to extend into the passage 7 and is herein shown as spaced from the walls of the passageway 7 in order to provide a channel for the flow of fluid through the body member. If desired the valve stem may be constructed in the manner illustrated in the aforesaid patent, the fluid flowing through the valve rather than around the same.

A chambered or cup-shaped operatin member 12 interiorly threaded is constructed to be secured to the threaded portion 6 of the body member, and by virtue of the cooperating threads is shiftable relatively thereto. It will be seen that one end 11 of the stem 10 projects into the interior of the operating member 12. This member terminates in an axial opening 13 and is provided with a-chamber 14: of any desired shape or capacity. The valve stem 10- is secured interiorly of this chambered member 12. In the present instance this is accomplished by means of a pin 15 driven through or inserted into alined holes or openings drilled through the end 11 of the valve stem and the walls of the member 12.

In the embodiment illustrated in Figs. 1, 2, and 3 the member 12 is provided with a wrench receiving portion 16, in the present instance of hexagonal configuration, and the pin 15 does not project beyond the outer walls thereof. This structure is preferably adapted for radiators in tractors. Due to the fact that the radiators of such machines are usually very close to the ground, it is important that all projecting operating handles or the like be eliminated in order to pre vent accidental opening of the valve. For ordinary automobiles the structure illustrated in Figs. 4 and 5 may be used if desired, in which case the body member 12 is not provided with a wrench receiving portion, but, on the other hand, the pin 15 projects through the cup-shaped portion 12 and serves not only as a means for securing the stem and member 12 together but also as an operating handle for manipulating the parts.

In operation it will be readily seen that by shifting the chambered member 12 relatively to the body member 2, the valve also will be shifted in the same direction in order to open or close the same. The valve is opened in a direction opposite to the direction of flow of the fluid thereby enabling the same to dislodge or break away any foreign matter which may have caked around the top of the valve head while in its closed position. By providing the member 12 with a chamber 14 greater freedom for the flow of fluid is provided and the scope of use of the device is broadened and increased.

In the embodiment illustrated in Figs. 1 to 3 inclusive the valve it will be understood is readily operated by means of a wrench applied to the portion 16, and in the embodiment illustrated in Figs. 4 and 5 the valve will be operated by grasping the handle 15 and turning the member 12 in the desired direction.

Although we have described our invention in its preferred form, it is to be understood that we do not limit ourselves to the construction herein shown and described except in so far as defined in the claims and embraced within the scope thereof.
