VALVE To all whom it may concern.:

Be it known that I, CHARLES l. VViLLiAMs, a citizen of the TJnited States, residingl at Vtica7 in the county of Oneida and State of New York, have invented certain new and useful improvements in Valves, of`

which the following is a specification, reference being had therein to the accompanying dra-wing'.

My invention relates to an improved valve, and i declare the following` is a full,

clear. concise and exact description thereof. sufficient to enable one skilled in the art to niake and use the same, reference being had to the accompanying' drawings in which like reference characters refer to like parts throughout.

rlhe invention is shown in a variety of l forms and coniprises the features and conibinations set forth herein, including' economy of construction and of space, simplicit v,

cleanliness and efficiency.

in the drawings, the views are of longitudinal sections of various forms of the device. F igures l and 2 showing' forms which are quite similar, but having' a di'ei'ent shut-off. Figs. 3 and show forms in which the valve is operated by a lever. Fig'. 5 is a view of a modified and simple form of the invention, and Fig'. 6 shows it as applied to4 a basin faucet. Fig. 7 is a view of a single member of the device. The other figures show the device used as a gage or try cock.

Referring to the figuresiin detail, l reprefrom one end to the other but at the outer end the passage is substantially enlarged, 1'

making a chamber 3. Means are provided for closing the smaller portion of the bore or passage7 between the supply or boiler and the chamber. in Fig. l as mounted to be screwed in to close the end of the smaller boi'e or part of the passage. In Fig. Q it is shown loca-ted transverse that bore. in Fig. 3 the shut-off bolt is indicated in a different position, in each case the casing being formed to provide a seat for the valve. in the other forms the cut-oft" is not shown but'inay be readily supplied in view of the showing made.

The opening' into the chainbei' 3 is threaded for screw plug 5 which is bored for Specification of Letters Patent.

Application led January 9, 1908.

This is a shut-off bolt 4e shown Patented .Tune l, 1909.

Serial No. 409,910.

' the valve stein 6. the inner end 7 of such bore being' finished to serve as a valve seat. in certain of the forms7 as will be seen, this bore is eccentric to the axis of the plug` to allow for the mounting` and swing of the Valve. and to make the device of compact forni. @ne particular feature of the device is this plug 5 which provides a removable l seat and having;l mounted on it the valve parts proper enables one to remove such parts for cleaning or renewing` in a very simple and quick manner. in F ig. 7 it is seen that the outer end of the plug is adapted for the use ofa wrench: it may be otherwise fitted for convenient manipulation.

thi the inner end of the plugand adja- `cent its periphery is stud 8, projectingl into the chamber 3, and on which is pivoted link 9 which is pierced at the other end for pin 10 which is loosely supported therein. On the inner end of the pin is head or nut ll, the other end extending into the bore of the plug` and adapted if desired for any suitable connection therewith of the stem G. in the forms shown in 5 and 6 the valve stein is extended to bear directly against the valve-disk and this forni may be used in the other instances shown, if preferred, the fluid pressure normally closing' the valve. On the pin l0 and between t-he plut;` 5 and the link '9 the valve-disk l2 which may be a. flat disk7 as seen in Figs. 5 and 6, or be of conical shape, or of other suitable forni, in each i case to contact with the plug which appropriately formed to constitute a valvei seat. The parts which compose the valve are so mounted as automatically to close under the pressure of the boiler or other supply.

` cap le is provided, screw-threaded to tit over the threaded end of the casing` and has outlet l5 which may be provided with nipple y or pipe 1G. ,it is bored for the Yalve stem (i to pass and be connected with the pin l() as by pivotal or link connection. In the forms shown in Figs. 5 and 6 this bore and the stein are threaded so that the valve is opened by turning;` the stem. But I pi'efer the forni of the device with means provided for the automatic closing of the valve, such as spring 17. ln Fig. 6 the spring' is within the valve cover being' secured to a footing' 19. ln this case the pressure of the spring, will automatically close the valve by rotating` i8 and connected with the stein as by pin' llO when the stem handle Q0 is released. ln other cases the spring 1T is on the outer part of the stem bearing against handle or wheel 2() and the cover or cap 14C. At the same time it is evident that, because of the formation of the casingl and the form and arrangement of the bore and chamber, and the manner in which the valve hung in the chamber the valve will be self-closing under the outward pressure of steam or other supply. In some of the .Figures a lever 2l and chain 22 are provided instead of handle or wheel Q0 for pushing in the valve stem. In such cases a. bracket 25 is suitably mounted on the cap to provide a bearing for the lever 2l.

Suitable means for packing the valvestem are shown in Figs. 3 and Il, the cap being provided with a nipple 25 on which bushing 26 is screwed. The nipple has an enlarged bore in the end which receives plug 27, held in by contact of its head with bushing 26, the packing` 28 being placed in the recess of the nipple and held by the rear end of the plug ln Fig. (i is shown an additional feature particularly applicable to such uses. lt consist-s in wall 2S) partially inclosing the recess 25o in the head of the cap or cover. .lt is bored for the stem 6 but not so closely but -that there is a slight leakage around the stem. The opening 3l, with the said leakage effects a siphon operation, the passage of the water through the outlet l5 drawing out the air in the recess o0 and subsequently taking olf the water that finds its way into the recess by the valve-stem.

A. particular feature of the construct-ion shown is that it is self-cleaning. In Figs. l, 2 and 5, for instance7 the swinging of the valve breaks up any sedin'ient or crusting that may collect in the chamber This is true in the showing in Figs. 3 and 4L `but not to so marked degree. ln the form shown in F 6 it is also true, but the particular advantage of my device in such use that there is no opportunity for sediment to collect on any part of the valve-disk or seatand the rush of supply when the valve is open will clean ott any thing that may collect on or about the parts of the valve.

Thile I have shown the invention as applied to a few uses, it is capable of wide adaptation, without depz'lrting from the scope of my invention.

Having described my invention, what l claim as new and desii'e to secure by Letters Patent7 is:

Il. In a valve, a casing having a passage therethrough. a plug removably mounted at one end of the passage and being bored to .provide a valve seat and a valve-closure means loosely supported on the plug opposite the bore thereof adapted to lit the valve seat and to be slid along its support to open the Yalve, substantially as shown.

2. A valve comprising a bored casing, a bored plug mounted in the bore, a valvestem, a link svvingably mounted on Vthe plug, a. piny loosely supported on the link and a closure member mounted on the pin adapted to move thereon to close the valve under fluid pressure and to be slid thereon by the stem to open the v: lve, substantially as described.

3. The combination in a valve, of a bored casing, an outer cap screw-mounted thereon, av plug screw-mounted in the casing, a valverlosure member and means swingably mounted on the plug and supporting said member movahly thereon along the axis of the plugbore. substantially as described.

l. ln a valve. a removable plug ii'tted to act as, a valve seat, means for closing the seat, a swinging support on the plug, said means being slidably mounted in said supA port and adapted to move in line with the axis of the plug. substantially as described.

in ar valve, a casing provided with a passage therethrough, a plug mounted in said passage and bored and formed for a y'alve seat at one end thereof` a swinging member mounted on the plug, a closure member slidably mounted on the swinging member. and means for pressing the said closure member from the valve seat, substantially as shown.

6. A valve comprising a bored casing, a bored plug mounted in the bore, a valvestem extended through the plug, a link swingably mounted on the plug, a pin loosely supported on the linkand a closure member mounted on. the pin in position to be forced by fluid pressure to close the bore of the pluO', the valve stem bearing against the face of the closure member, with means whereby to :force it from said plug, substantially as described.

ln a device of the character described comprising a bored casing, a plug screwmounted in the bore, itself being` bored at one side of its axis and provided with a valve-seat at one end of such bore and a closure member for such valve-seat loosely supported in position to be forced by Huid pressure closely to register against said valve-seat, a cover removably mounted on the casing and a valve-stein supported in the cover and adapted to force said closure member from said valve-seat, substantially as described.

In testimony whereof I atlix my signature in presence of two witnesses.
