T all whom it may concern I Be it known that- I, JOHN J. :KINEHAN, acitizen of the United States, and a res dent of Los Angeles, county of Los Angeles, and
State of California, have invented certain new and useful Improvements in Air-Tube Valves, of which the following is a specification. Y
My invention relates 'toair tube valves of the character used with pneumatic the tubes, and has among itssalient objects to provide a more simple, a more economical, and a more durable device of the character referred to, and to also provide'a device of the fewest possible parts which shall be more easily assembled and taken apartthan is possible with devices of-this character now on the market I have illustrated my. improved air tube valve on the accompanying'sheetf of drawf ings, in which, I Figure '1 shows a disassembled 'view, ,of all the parts of my improved valve; Figure 2 is a side elevation of the complete valve, partly in section; l 'Figures 3, a, ,5 and Gare cross sectional views, respectively, takenon the correspondin lines on Fig. 2. i i p eferring now in detail to the drawings,
my invention comprises a- ,tubular body 7 exteriorly threaded and having fiatopposite sides without threads, as at 8. Sa-id body is provided with an open cup-like portion 9, of comparatively thick" form so as to provide a round edge at 9 to preventppssible cutting of the tube at a point opposite said valve when the tire is deflated. My tube has a straight bore of uniform diameter, as shown. Cut around the inner wall of said cup-like member is a groove 10, adapted to receive a retaining member or expansion ring 11, provided with kinks or inwardly pr0 ecting portions 11'. Mounted through the tubular member is a valve stem 12, of cora paratively large diameter and uniform throughout the principal part of its length. At its opposite ends. said valve stem is reduced in size and threaded as shown. Mounted on the inner end of said stem is a special rubber gasket 13, of disc form and provided, as a part thereof, with a conical extension 13'. This gasket fits the reduced inner end of said valve stem and its conical extension bears against the shoulder of the stem, caused by its reduction in diameter.
, a hand 7' Specification of Letters Patent. Patented DI/[31; 14 .1922; Application'filed March '27, 1919. Serial No. 286,163..
Screwed on to theend of the stem is a metal disc or valve member 14:, "and this is held in place by a small nut15. .The valve 14 is beveled around its upper edge and this bev eled part is adaptedfito be engaged by the. inwardly directed project-ions.1lof the re taming member 11. The
the beveled portion thereof at a point. beyond the outer'edge so as to limitthe movement of the disc and hold theouter edge thereof spaced from the retaining ring. This construction and arrangement allows sufficient space for the air to pass betweenthe outer edge of the valve and the retaining ring. The tubular member,' 'ithin'the cup portion s countersunk, as at 7, whereby the conical part of the gasket .13 fits l c1se1' umvahout sticking, into i the tubular member. After the gaskethas' been placed on the end of. the stem 12, and the disc lt and the nut 15 have been placed, the stem is inserted through the tubular member and the expansion holding member diameter thanth'e-interior diameterof the cup so that they move freely. The retaining member 11 isplaced; suiiiciently away from v85 said disc valve member 14 so as to permit it I p v projections 11' will overlie the edge of the disc so 'as' toengage said countersunk bore into move in and out.. "Attention is= also.ca1led to the contacting area of the gasket against the bottom-of the cup,in*addition to the contact of the conical portion of the gasket in the bore. The area of the valve memberlt is suchthat the airpressure in the air tube normally holds said valve seated and quickly again seats it after it has been moved inwardly. The outer end of the valve stem 'is provided with a holding cap '16 which screws onto the end of the stem'within the end of the tubular member, but isnot attached to the tubular member, other than to bear against the end thereof, as shown. The tubular member is reduced at its end and threaded as usual to receive the filling tube of a pump when it is necessary to use pump, but this'is common construction. One of the great objections to tube valves now in use isthe diliieulty in taking them apart'and the 'constructionwhich causes the gaskets to wear rapidly. 'Hy gasket is not folded or expanded and will, therefore, have little or no wearwhatever. The cup and the valve disc 14 are wholly within the tube, thus eliminating complicated construction in the interior of the tubular member.
I claim:
1. An air valve of the character shown comprising a tubular body having atone end an enlarged open cup the bottom of which constitutes aflat metal valve seat with a central opening therethrough communicating with the opening through said tubular body, said cup having an internal groove around its inner face, a valve rod extending through said tubular body and into said cup, a disc secured to the end of saidrod within said cup, a gasket having a fiatseating surface adapted to seat fiatwise on to the metal valve seat formed by the bottom of said cup, said gasket having a central opening therethrough fitting closely around said valve rod and under said disc and moving with said disc within said cup, and a spring retaining ring member adapted to the internal groove in said cup and having inwardly projecting portions for limiting the movement of said j valve within said cup without obstructing the passage of air through the valve when said valve member is against said retaining ring, said retaining ring being split whereby it may be rea'dily inserted in the internal groove of the cup, substantially as described.
2. An air valve of the character shown and described comprising a tubular body having at one end an enlarged open cup, the bottom of which constitutes a flat metal valve seat with a central conical opening therethrough communicating with the opening through said tubular body, said cup having an internal groovearound its inner face, a valve rod extending through said tubular body and into said cup, said rod being reduced in size within said cup to provide an annular shoulder thereon, a disc gasket having a central conical extension and mounted on said rod within said cup with its conical extension bearing against the annular shoulder on said rod, ainetal disc on said-rod resting fiatwise against said gasket, means holding said disc on the end of said rod and bearing against said gasket, the conical extension on said gasket fitting the conical opening through the bottom of said cup and the fiat face of said disc gasket bearing flatwise on the bottom of said cup, and a spring retaining ring in said groove in the face of said cup and having projections for limiting the movementof said valve member within said cup, said retaining ring being split whereby it may be readily inserted in the internal groove of the cup, substantially as described.
3. A valve of the character describeu com prising a tubular body having an enlargementon one end, a flange formed around the enlargement and provided with a groove in its inner face, a rod extending through the tubular body, a disc secured to the rod and adapted to engage the enlargement of the tubular body, said disc'being of less diamet'er than the interior diameter of the ,flange around the enlargement so as to leave a space between'the outer edge of the disc. and inner face of the flange and having. its outer face beveled around the edge, and a spring retaining ring received in the groove in the flange,'said retaining ring having inwardly extending projections adapted to overlie the edge of the disc and engage the beveled portion thereof at a point beyond the outer edge'so as to limit the movement of the disc and hold the outer edge thereof spaced from theretaining ring.
