' ~ Describing the invention broadly with refer ence to the accompanying drawing, A designates as an entirety automobile or ventional cap upper end of 55 the conventional valve stem of an similar tire inner tube. The con which serves as a closure for the this stem is designated as an en tice the ‘upper end Of the valve stem 'isthrea'ded ‘as indicated at ‘l, and that the-cap B is oi'c‘oni ventibnal form in that ‘it has a lower skirt'por tion ‘2-,’ which is ‘internally threaded to receive the upper threaded end portion l of the valve stem. Above this skirt portion the'cap is en; 10 larged tol’form a band 3, which is externally vroughened and which in conventional use con~ 'stitu‘tes a ?nger receiving portion by means of which the cap can be readily rotated forremoval ‘from or application‘to the valve ‘stem. Above this ‘roughened band ‘portion 3, ‘the'i‘cap still fol lows its conventional‘iorm in having an elon gated portion ‘4 of reduced diameter having in its upper end a kerf 5, which'is adapted ‘to co operate with the valve ‘(not-shown) for tight'em 20 ing it within ‘or ‘removing it from the hollow ‘valve stemh. ' I > » r - > ' An internally threaded nut 6 is adapted to be applied to the upper threaded-end portion I of thevalve ‘stem' and by rotation moved downward~ 1y ‘thereon to'assuine the position clearly illu'se 25 trated in they drawing, whereby vit is consider ably below the ‘upper end of the stem'and forms a circumferential enlargement at the baseof the threaded‘ portion of‘ the stem and also forms a circumferential shoulder “l, the function of which will hereinafter- clearly ‘appear. 30 ' The cap ‘retainer and ‘closure ‘C is made of rubber or other like ‘and suitable ?exible ‘or ‘elastic material andjcomprise's a hollow upper ~ end or'he'ad ‘portion 8, which completely em‘ braces and vretains under resilient tension the cap skirt portion 2 and roughened 'band‘portion 3. The top 9v of the head is provided with an opening to permit passage therethrou‘gh of tin 40 elongated reduced portion A of the cap and ex“ tends 'ove‘rand resiliently -'e'ngages the/curved portion [0 of the cap immediately above the can band 3‘. Additionally, ‘the head -8~-is~ preferably of a ‘length to extend below the lower ‘end ‘oi-"the cap skirt portion 2 as clearly appears at H. In addition to its head portion 8 the cap re tainer and closure C comprises a lower ring por tion l2, which is carried by and connected to tirety at B and the cap retainer and carrier which is also a water and dirt-proof closure, is the head portion by two oppositely disposed nar row side wall portions I3 and M, which provide oppositely disposed windows I5 in the carrier. ; The lower ring portion H of the retainer is designated as an entirety at C. Proceeding now with a detailed description of positioned on the valve stem at a point below the nut Grand has an internal diameter greater than 55 2,136,002 2. the diameter of the valve stem, with the result that it is free to either rotate or reciprocate upon the valve stem, but is of an internal diameter less than the outer diameter of the nut 6 with the further result that the ring in its movement can not pass upwardly over the nut or by the cir cumferential shoulder 1 formed by the nut on the valve stem. ~ 7. V , edge of the windows I5 and because of this, the part C of the closure carrying the said cap is more readily movable laterally to the position shown in dotted lines in Figure 2. It will be seen, of course, that the side wall or arm portions I3 and I4 are of suf?cient length to afford the necessary longitudinal movement of the retainer to permit the rotary removal of the cap Brfrom the valve The construction of the cap carrying closure stem and that when the retainer.is swung to C is also such that the side wall members I3 and either side of the valve stem that the upper end of 0 I4 which unite the ring to the head do not engage , the stem will extend through one of the windows or bind upon the stem nut 6, or in any way hinder I5 and be available for the application of an air the free rotation or reciprocation of thering I2 hose or the like. on the valve stem. From the foregoing description it will be'seen With a construction such as described, the cap retainer and‘closure provides a dust and mois that when it is desired to apply an air hose or ture-proof protection for the valve and constitutes pump hose to the valve stem to in?ate the tire a positive carrier and retainer for the cap to prevent ‘it from being lost or misplaced. While serving the double function of a cap carrier and protecting closure the structure is such that it is tube, the cap B is removed from the stem in the ordinary and conventional way, viz: by rotation. When the cap retainer and closure has‘been ro tated‘suf?ciently to disengage the cap from the threaded portion of the stem, as illustrated in Fig. 2 of the drawing, the retainer can then be swung or moved against resilient tension of the side walls of the arms I3 and I4 to either side of the valve stem as is illustrated in dotted lines in the before referred to Fig. 2 of the drawing. Attention is especially directed to the fact that by unscrewing the cap B from the valve stem I, the lower part of members I3 and I4 and the ring I2 of the rubber closure C are also rotated around the valve stem and the nut 6, since the in no sense an obstacle to the easy and rapid re moval or replacement of the conventional metal valve cap B and is not in the way when .it is found necessary to in?ate or- de?ate the inner tube. ' ‘ ‘ Attention is directed to the fact that the pres ent invention can be quickly, readily and cheaply applied to and used in connection with any con ventional inner ‘tube by merely vapplying to _ the upper end of the tubevvalve stem the nut 67 or its equivalent. Thus the present invention con stitutes a novel and useful appliance which can parts of the closure ?t loosely the valve stem and the part 6. By reference to Fig. 2, it will be ‘ob be cheaply manufactured by reason of its sim plicity and which should have a large volume of served that when the cap B is unscrewed.- from the part I of the valve stem. the closure can move sale by'reason of its highly‘ desirable attributes vertically until the part I2 engages the member 6. In Fig. 2 the parts are shown in this posi tion, and in said ?gure the cap B and the part C 540 are shown in dotted lines to be moved tosub stantially horizontal positions. After the air is supplied or removed through the valve stem A and the hose through which the air is conducted to the inner tube is removed, then the valve and the part C will automatically return to a verti cal position when they are permitted. . In'order to place the valve cap B on the threaded stem I, it is necessary to depress the valve cap which also depresses the closure until the cap engages and numerous prospective purchasers. v I claim: ' , .
