VALVE.

1' b all whom it may concern:

lie it known that I, FRANK M. Asnmcv, a citizen of the United States, residing at (53 Central Place, Brooklyn, in the county of Kings and State of New York, have 111- vented certain new and useful Improvements in Valves, of which the following is a full, clear, and exact specification.

This invention relates to valves and its objoct is to provide a simple and eflicient c011- struction of that type of valve wherein the valve seat can be removed for grinding or cleaning, or for replacement by a new seat.

A further object is to provide a construction wherein the interior of the main valvebody will not require an exact finish by reason of the employment of a separate interior part or parts involvin the removable valve seat, and the desired nish.

\Vith the above and other purposes in view, the novel valve comprehends the improved construction set forth in the subsequent detailed description.

In the accompanying drawings forming part of this specification,-Figure 1, is a sectional view of a valve embodying my invention. Fig. 2, is a view of similar character illustrating a modification of a valve. Figs. 3 and 4:, are plan and vertical sectional views respectively, of the seating proper. Figs. 5 and 6, are sectional and plan views respectively, of a modified form of the inner ring seating.

1, represents the body or casing having the usual inlet and outlet openings 2 and 3, interiorly threaded for the engagement of the pipes 4 and 5, the chamber within the casing being divided by a wall 6, containing the seat opening 7. Upon one side of the wall 6, is the bonnet opening 8, in which is fitted the cylinder 9, the latter having a lower annular portion resting on the wall 6, and surrounding the opening 7.

It will be notedthat the wall 6, im mediately surrounding its opening 7, cmbodies an annular raised seat 6 the lower end portion of the cylinder 9, containing in its under side, an annular groove which permits said portion to fit over said raised seat 6 with the circular surface forming the opening in the said portion flush with the corresponding surface in the wall 6. The lower annular portion of the cylinder, also presents at its upper side a raised seat 10. It will be advantageous to interpose a ring 12 of packing material between the seat 6,

and the grooved portion of the cylinder resting thereon, as such employment of the packing will obviate the necessity for accurately machining these parts.

13 refers to the usual cap or bonnet held in engagement with the valve-body either by screw threads 14.- as shown in Fig. 1, or by means of an independent threaded ring 15, as indicated in Fig. 2, the cap in either i11- stance acting to hold the cylinder down upon the wall 6, either by bearing directly upon the upper end of said cylinder or through an interposed ring 16, of packing material. The opening 17, is in one side of the cylinder to furnish the requisite passageway. The valve stem may be adjustable in the cap 13, by threads 20, or otherwise. If preferred, the cylinder 9, may comprise a plurality of parts, Fig. 5, illustrating a construction wherein the seat 10 is in one piece 35, and the body of the cylinder in another piece 36.

It will be seen that when the cylinder and its seat are removed for repair or for other purposes, the valve can still be used as the character of the raised seating 011 the wall 6, and the lower face of the valve are such that the said valve will squarely, adequately and efliciently secure a bearing on said seating, the tightness of the joint being au mented by the presence of a ring 19, of yielc ing n1aterial in the underside of the valve.

With a view of further preventing any turning of the cylinder and its seat, the cylinder body externally contains a vertical groove 22, which as the cylinder is introuced in position, is adapted to have enaged therein a lug 23, integrally projecting from the contiguous part of the valve body.

The construction set forth is simple, comparatively inexpensive and easily maintained in good condition.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is-

1. In a valve of the character described, the combination of a body portion having an internal lug at one side, said body portion also containing a dividing wall presenting an opening and raised ring seat surrounding said openlng, a cyhnder with a groove engaged by said body-lug and with a lower portion embodying a raised ring seat and containing an under groove for receiving the seat of the dividing wall, the surface forming the opening in said lower portion being flush with the corresponding surface in the wall, a ('31) confining said cylinder and holding the lower seat portion in bearing engagement with the dividing wall and a valve Htclll guided through the cap and carrying a valve for coaetion with either of said seats.

:2. In a valve of the character described, the combination of a body portion liavii'ig an internal lug at one side, said body portion also containing a dividing wall presenting an opening and raised ring seat surrounding said opening, a cylinder with a groove engaged by .said body lug and with a lower portion enilmdying a raised ring seat and containing an under groove for receiving the seal of the dividing wall, the surface forming the opening in said lower portion being {lush with the correspondin surface in the wall, a cap confining said cy inder and holding the lower seat portion in bearing engagement with the dividing Wall, and a valve Hl'Clll guided through the ca 3 and carrying a valve for coaction with eitier of said ring seats, said valve having a yielding face.

In testilnonv whereof I afiix my signature, in presence of two witnesses.
