`TIRE OR OTHERVALVE.

`SHPECIFICLA'JJION forming part of Letters Patent No. 685,649, dated October 29, A1901, Application filed April 8, 1897. Seria] No. 631.250. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE H. F. SCHRA- DER, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Tire or other Valves, of which the following is a specification.

This invention relates to pneumatic and other valves of the class known as tirevalves, and aims to provide certain improvements therein.

Heretofore tire-valves have been constructed with a shell having an internal valvechamber and seat, a valve proper within the chamber, and a spring for seating the valve proper. Imperforate plugs and disks have been used as the valve proper and have been t A one form of tirev'alvelxed to the cot of a pneumatic tire, the cot and tire being shownV fragmentarily in section. Fig. 2 is a vertical axial section thereof, the parts being in a closed position. Fig. Bis an axial section of the valveshell, showing the internal parts in elevation and in the open position. Figs. 4. and 5 are respectively cross-sections on the lines 4 4. and 5 5 of Fig. 2, and Fig. 6 is a cross-section on theline 6 6 of Fig. 3. Fig.` 7 is an axial section showing a modification. Fig. 8 is a similar view showing another modification, andv Fig. 9 is alike View showing the valves in Fig. 8 in the open position.

The valves shown are all ofthe style known as cOt-'valves;7 but my improvements are equally applicable to any other construction of valve.

In-the drawings, A represents a tire; B, the y valve proper; G, the valve-spring; i H, the deflater, and I the plug closing the inner end of the shell. These parts may be of any usual or suitable construction, the example taken being chosen as a convenient construction of valve to which my improvements are applicable. In this construction .the shell is tubular andA has an outer screw threaded socketa, a contracted neck b, leading to the seat, a shoulder c in this neck, and a duct d through the plug I, communication through the shell traversing these parts and the valve-chamber by passing around the valve proper when'the latter is unseated. The cap screws on the usual outer thread'of the shell and has a finger e for entering the socket and depressing the deiiater to unseat the valve proper. p u The valve proper shown consists of animperforate piece of rubber or other packing materialf and an'inclosing holderg. The y vdeiiater and valve proper are separate and independently-movable parts, the deflater being confined within the shell' by an enlarged end h, which cannot pass the shoulder cin the neck and which rests against the body f when pressed inwardly for unseating the valve. f

Referring now to Figs. l to 6, I will first dei scribe in detail the preferred form of my present improvements. According toone feature of improvement Iconstruct the valve proper u' with longitudinal externalA guiding ribs (i, which project from lits sides aud make a suit-u able t with the cylindrical walls of the cham-y ber D and leave spaces between them lfor the free passage of air. These ribs are prefer-v ably formed in the Wall of the casing g, which is shown as a staniped-lnetal cup having portions ot' its sidewalls bent orcreased outwardly to form projections constituting the` I ribs According to another feature of irnprovement I provide a valve proper of the imperforate type with guiding provisions at itsinner or egress side-'that is, the side re? mote from the seat-these provisions consti tuting'reoiprocal faces carried bythe valve proper and the shell at the egress side and in sliding engagement sufficient to preserve the position of the valve within the chamber, While not interfering with its proper'movement. Preferably the valve is provided with an inwardly-projecting rigid tail J and the loo plug with a smooth guiding-socket K, .receiving this tail, remote from the valve proper. The tail J may be suitably constructed and connected to the valve proper. I prefer to form it of a cylindrical rod, the upper end of which is riveted to the casingg by being passed through a hole j in the bottom thereof and swaged to overhang this hole within the casing below the plugfand to provide afree passage-way between the rod and the socket by cutting away a part 7c of the rod at its lowerend-for example, by squaring it there, as shown. The guiding-walls K are preferably formed in the plug I, these walls heilig in the construction shown also the walls of part of the duct (Z. The rod extends from the valve proper to the plug and sufficiently within the latter to give the requisite guiding engagement. I preferably provide also an intermediate guide for the tail of the valve propel'. This is shown as a tubular part L, fixed within the chamber Gand located therein by a shoulder l. This part bridges the chamber and has cut-away sides m, permitting free passage-way through the chamber, a cylindrical bore n., fitting the tail J, and a cross-cut o, exposing the tail at its side. This part in the construct-ion shown surrounds at its top the cylindrical part of the tail and at its bottom the cut-away part thereof and suffices as a bridge for carrying the spring G. The valve-chamber is shown as slightly enlarged to receive the part L and provide the shoulder l therefor.

In use the valve proper will be properly guided in the construction shown both near its seating end, at the extremity of its tail, and intermediate of these points. This permits a sufficiently free fit to give great sensitiveness of action and still avoids .any danger of disadvantage from looseness. All liability of the valve to becomeimproperlyseated or to catch or cant is obviated. The side ribs will remove any danger of the spring jamming between the chamber and casing.

' With imperforate valves these dangers have been material, and guiding other than through the length of the valve proper itself has been difficult, if notimpossible, of attainment.

In operation the improved valve will be used as former valves of this class have been, the separate defiating-pin being em` ployed or not, as desired. The valve proper will unseat to permit inflow and seat to prevent outfiow, the air passing in the space or spaces between the Walls of the casing and shell.

It will be understood that my invention provides improvements which can be readily and advantageously availed of in whole or in part and that I do not limit myself to the particular details of construction and combination set forth as constituting the preferred form of the invention, but that the invention can be employed in whole or in-part, according to such modifications or combinations of its several features of improvement as circumstances or thejudgment of those skilled in the art may dictate, without departing from the spirit of the-invention.

In the construction shown in Fig. 7 the intermediate guide is omitted, the tail J being here flattened at its end 7c and guided by the socket K in the plug I. The shell B lxasits valve-chamber of uniform diameter, and the valve proper, F', consists of a thin fiat imperforate disk of rubber f' instead of the elongated cylindrical plug before described, which disk is fixed within the inturned edge of a shallow metal casing or cup g', to which the tail is fixed. No guiding-ribs are shown on this cup.

In the modification shown in Figs. 8 antlU the shell B is of the same construction as that shownin Fig. 7, and the valve propel', F, consists of a short imperforate plug f and along metal casing g, the guiding-socket K" being in this instance formed in the valve proper or the casing thereof, While the guid ing-tail J is in this instance formed on or earried by the plug I. The casing g has the ribs t', before described, and extends a considerable dist-ance below the plug, having a large holejin its lower end. The guiding-tail Jis shown asa fingerprojecting from the plug I nearly to the valve and entering the hole in the casing, so that the end of the `finger projects into the socket K". The casing is thus guided in its vertical movements by the finger. The end of the finger strikes the plug f and arrests inward movement of the valve proper. The outlet-duct through the plug is here lettered d. A spring Gis shown as surrounding the tail J" between the plug and valve proper.
