RENEWABLE-SEAT VALVE.

SPECIFICATION forming part of Letters Patent No. 647,192, dated April 10, 1900.

Application filed December 4, 1899. $erial No. 739,185. (No model.) i i of which the following is a full, clear, and

exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to. that class of valves among which may be enumerated globe- I valves, check-valves, inthe form of globe and angle valves, and, in short, an that class of valves having an inlet-openin g, a pipe-opening, and an interposed-valve-seat opening, with a valve-seat covered by a valve that moves to and from its seat always in planes for its object the provision of a removable and renewable seat for this class of valves which can be readily applied and removed without trouble or loss of time and without disconnecting the valve from its pipe-fittings, thereby greatly increasing the efficiency of the valve and prolonging its life.

The novelty of my invention will be hereinafter set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure l is an axial side elevation of so much of a globevalve as is necessary to illustrate my invention. Fig. 2 isa transverse elevation of the body of the valve on the dotted line ano of Fig. 1. Fig. 3 is a plan View of Fig. 2. Fig. 4 is a sectional side elevation of so much of an angle-valve as is necessary to show the application of my invention. Fig. 5 is a central sectional elevation through the neck of the valve,showing a modification wherein the bonnet or cap is interiorly threaded to screw upon the exteriorly-threaded neck of the valve. Fig. 6 is a central sectional side elevation of a check-valve in globe form embodying my invention. Fig. 7 is a sectional elevation of the neck in detail to show more clearly one of therecesses in the threaded part of the neck, into which one of the arms for the ring-seat is seated deeply enough so as to not interfere with the threads of the bonnet or part thereof which screws into said valve and its securing-arms in one piece.

Fig. 10 is a view at; right anglesto Fig. 9, showing the securing-arms attached toa ring and with the ring-seat beneath the .same as a separate detachable piece.

The same letters of reference are nsedto indicate'identical parts in all of the figures.

In Figs. 1 .and 2, which representan ordinary globe-valve or so, ln uohlthereof as is necessary toillustrate my invention, A represents the body, with opposite pipe-openings a b to form inlet andoutlet openings for the valve. Within the body between these open ings (t l) is the usual diaphragm c, having through it an opening containing the valveseat D, with which the valve 0 (represented by dotted lines) engages and is moved to and from the valve-seat to close and open the valve by the usual or any suitable stem f passing through and engaging with a cap or bonnet B, screwed to the neck 0 of the valve.

So far the construction described is that of any ordinary globe-valve, and I will now pro- .ceed to describe the application of myinven- -tion thereto.

Loosely fitted within the valve-opening in the diaphragm c is a removable ring-seat D, with an exterior rabbet or cut-out portion g to fit the opening in the diaphragm and with an upper interior beveled portion h to form the valve-seat with which the correspondinglybeveled lower portion of the valve 6 engages. In one of its forms the ring-seat D has integral with it two or more upwardly-projecting arms E, which are fitted into and are guided by recesses "6, Figs. 3 and 7, in the neck of the valve, whether the same be threaded or not, and which arms extend up far enough to be engaged by the flange of the cap or bonnet B of the valve, so that when the latter is screwed down to place it engagest'he tops of the arms E and forces same downward to cause the ring-seat D to snugly adhere to the opening in the diaphragm of the valve to prevent leakage. These arms E may be nicked or corrugated, as atj, Figs. 2 and 9, so as to be longitudinally compressible and thus be in a measure elastic when the cap or bonnet is screwed down. As a substitute for these nicks or corrugations the upper ends of the arms may be perforated, as seen at Ya, Fig. 10, to enable-the longitudinal yielding or compression of the arms andv also to serve as a means for introducing a hook or other tool by which the arms and ring-seat or ring carried by the arms can be withdrawn from the valve-body to enable a new ring-seat to be applied, as will be readily understood.

As seen in Figs. 1 and 2, thering-seat and armsmay be integral, and, as seen in Fig. 10, they may be detachable with an upper ring Z, carried by the arms E, fitting upon a rabbeted portion of the ring-seat D just outside of its seat h, 'as'shown particularly in Fig. 10.

In Fig. 4 the invention is shown as applied to an angle-valve of well-known form-of construction, and wherein the ring-seat and arms may be integral or separate, as in the globe form above described.

Again,'in Fig. 6, I have shown a well-known form'ofcheck-valve to which my invention is 'applied',the cap or bonnet being indicated by 'dottedlines and only the'us'ual guidewings for the valve being employed.

In Fig. 8 I have shown a form of cap or bonnet having an inwardly-projecting screwplug m,which bears upon and forces down the tops of the arms E, and in Fig. 5 I have shown the bonnet B as having a threaded flange engaging the outer side of the neck 0, inwhich case tlie'arms E extend far enough u pto be engaged by the inner projecting lower side'of the capor bonnet.

- I have thusshown the application of my invention in a variety of ways to a variety of forms of valves, but do not intend that the same shall be limited thereto nor that my claimsfin terms,should beconfined to the same, as the leading features of my inventionare the location of the removable valve-seat with reference to the valve which engages it, the arms that hold said seat to its placein the seat-opening of the valve whether the armsare integral with the valve-seat or are attached to an intermediate ring that engages the seat; also, in so guiding the arms and in supporting them inthe neck of the valve in recesses that no torsion or twisting is exerted upon them in securin g thecap or bonnet in place and whereby'the valve-seat will always be seated true and will remain so under all circu mstances,the whole forming a very simple and efficient means of applying renewable seats to this class of valves, which will render them perfectly efficient in action and will greatly prolong their life and utility..

As-another valuable feature of my invention it is to be observed that neither the size of the valve body or shell or its neck is in the least increased or enlarged nor is the opening or passage-way through the valve in the least restricted, owing to the fact that the arms that hold the renewable valve-seat are at one side and do not in any way obstruct the passage of the valve, so that my invention is applicable to the standard sizes of the valves now on the market, to which it can be applied in a very simple and cheap manner. Also, while I have shown forms of valves where the caps or bonnets are screwed to the neck, yet it is well known in the art, particularly in the construction of iron valves, that these caps or bonnets are sometimes flanged and secured by connecting bolts. Even in such cases my invention isperfectly applicable to these latter forms of valves and will be found very desirable in theirfuse,

It will be seen from the foregoing that the two principal features of my invention are, first, to provide a holder for the renewable seat that does not in any way obstruct' the passage-way of the valve, and hence thetwo arms are arranged at the opposite sides of the shell out of the passage-way of the valve, and, second, to provide means to preventany turningor displacement of. the arms, espe cially on account of the screwing down of the cap or bonnet. It 'is evident that any suitable stops for that purpose'wonld answer justa's well, and I therefore, do notwish'to be confined to any, particular way, of preventing thearms from turning. i
