VALVE MECHANISM.

Speeieation of Letters Patent.

Patented July 30, 1907.

Application tiled January 2,1906. Serial No. 294,254.

To all whom it may concern:

Be it known that JOHN PHILLIPS MERN, a citizen of the United States, residing at Brooklyn, in the county oi Kings and State oi' New York, has invented a new and useful Valve Mechanism, of which the following is a specification.

This invention while relating more particularly to valve seat structures of hydrants, is not necessarily limited thereto, but may be advantageously employed in other apparatus, wherein valves are used.

The principal object oi the invention is to provide a novel and simple valve seat that can be readily placed in position and removed, so that' if the valve mechanism becomes worn or deranged, access thereto may be readily gained, and the injured or inoperative parts repaired or replaced with ease and expedition,

A further object is to provide securing means for the valve seat, whereby the latter may be effectively fastened in the casing, said means also preventing leakage through the joint between the seat member and casing.

The preferred embodiment of the invention is illustrated in the accompanying drawings and described in the following specification.

In said drawingsz-Figure l is a vertical sectional view through a hydrant showing the valve mechanism in place therein, together with the positioning and locking tool employed in connection therewith. Fig. 2 is a sectional view through the said mechanism on an enlarged scale. Fig. 3 is a horizontal sectional view, taken on the line 3 3 of Fig. 2. Fig. 4 is a horizontal sectional view on the line 4 4 oi Fig. l. Fig. 5 is a detail perspective view of the valve seat member. Fig. 6 is a side elevation of the head of the tool employed in positioning and securing said member.

In the embodiment illustrated, a coupling elbow or casing 7 is employed having a valve chamber 8 therein, and an upper inwardly extending wall portion 9 provided with a central opening l0, forming a valve seat receiving socket. A casing 1l is suitably mounted on the elbow or casing 7, and is provided at its upper end with the usual outlet nipples l2. The inwardly extending wall portion 9 of the casing 7 is provided with spaced lugs 13, and the marginal portions 0i said wall about the opening 10 is beveled, as shown at 14. This beveling includes the upper sides of the lugs 13, as shown in Fig. 3.

A detachable valve seat member in the orm of a sleeve l5 is employed, which sleeve is arranged to enter the opening 10 between the inner ends of the lugs 13. The lower portion of said sleeve is provided with a plurality of outwardly extending lugs 16 arranged to pass through the spaces between the lugs I3 of the casing and engage the underside of said lugs 13 after having been so passed through, and upon the turning of the sleeve. Stops 17 arranged at the ends of the lugs 16, limit the said turning movement. An intermediate portion of the outer face of the sleeve or valve seat member is beveled, as shown at 18. This portion is disposed in opposition to the beveled margin 14 oi the casing wall 9 when the sleeve is in place therein. The upper end of the sleeve is exteriorly threaded, as shown at I9, and screwed thereupon is a clamping nut 20. A packing gasket 2l preferably formed of shee't lead or other suitable ma-l terial is arranged beneath the clamping nut, and is adapted to be i'orced thereby into the tapered annular recess formed by the beveled portions 14 and 18. The lower end of the sleeve 15 is interiorly beveled, as shown at 22, forming an annular seat to receive the usual valve 23, said valve being carried by the lower end of the stem 24 extending longitudinally through the casing ll and operated in any desired manner.

The clamping nut 20 is provided with upwardly extending studs comprising stems 25 having heads 26 at their upper ends, These studs are arranged to be engaged by the lower disk head 27 of a positioning and securing tool 28, the said head 27 being carried by a tubular shank 29, having a suitable handle 30 at its upper end, the shank being oi su'llicient length to pass downwardly into the casing, so that the head 27 will engage the studs. This head, as shown in Fig. 4, is provided with slots 3l, the intermediate portions oi which are of sufficient size to permit the heads 26 of the studs to pass therethrough, said slots tapering in opposite directions, and the end portions being of less width than the diameter of the head 2G, but of suiicientl width to receive the stems 25 oi the studs.

It is believed that the application of the valve seat structure to the casing may now be readily explained. In practice, the upper ends of the threads oi the valve seat sleeve l5 are preferably mutilated sufficiently to prevent the nut from completely unscrewing therefrom. This nut is raised to its highest point upon the sleeve, and the studs are engaged in the slots 3l of the head 27 oi the positioning tool. It will thus be clear that the valve seat member is attached to the tool and can be lowered into place. After the lugs I6 of the member' have been passed through the space between the lugs 13 oi the casing, the teol is turned, thereby rotating the sleeve and bringingthe lugs 1G beneath said lugs 13. When thus positioned, the stops 17 will prevent the further rotation oi the sleeve, so that a continued revolution of the tool will cause the clamping nut to -be screwed downwardly upon said sleeve.

Asaresult, the packing washer or gasket will be forced Spaces between the lugs f the Casing and engage the into the joint between the sleeve and casing wall 9, and consequently leakage therethrough will be prohibited` At the same time, the said nut will draw the valve seat sleeve upwardly, and securely clamp the lugs 16 against the lugs 13 of the casing, thereby effectively securing the device in place. When the parts have been thus disposed, it only becomes necessary to turn the tool 30 in the reverse direction until l0 the headed studs of the nut are in the intermediate portions of the slots 3l., whereupon said tool may be detached. To remove the valve seat member, the reverse of the above described operation is all that is necessary. It Will thus be seen that an exceedingly simple and effective valve structure is provided, which can be removed and replaced Whenever found neces sary or desirable.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein 20 described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrific- `ing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent,

isz-
