DUST CAP.
Application led llarch 13, 1922. Serial No. 543,382.
.' open end an integral inclined flange adapted to firmly grip the valve tube to seal such end of the cap to preventI entrance of dust and moisture and to aid in preventing the dislodgment of the cap, and adapted in the body portion to have its interior fully occupied by the valve tube and to grip the threads of the tube to further insure against the dislodgment of the cap except when drawn off' by the hand, which may be done due to the yieldability of the rubber.
In the accompanying drawings:
Fig. l is an elevation of a portion of a wheel rim having a tire, a conventional air valve tube and my improved cap applied thereto;
Fig. 2 is an enlarged sectional view on the line 2-2 of Fig. 1;
Fig. 3 is a detail view of my improved dust cap in longitudinal section; and
Fig. 4 is an end view of the base of the cap.
The conventional wheel rim is indicated at 1, with spokes 2, a detachable ring 3 and a tire 4, with a valve tube 5 extending through the rim and connected (not shown in any a proved or the usual manner with an inner tu e, (also not shown). This valve tube has an exterior thread 6 with a binding nut 7 which abuts the rim 1. This tube also has a reduced threaded neck 8 over which is screwed the usual valve cap 9. All of these features are of any of the types now commonly in use.
Referring new more directly to my improved rubber dust cap the same is designated generally by the numeral l0. lit consists of a tubular body closed at one end and open at the other. At the open end it is provided with a sealing and gripping flange 11 which inclines inward so that when the cap is sli ped over the valve tube 6 the flange will yield somewhat to facilitate tne sliding movement. whereas any tendency of the cap to slide 'off is resisted by this flange because of the tendency of such a movement to spring the flange in the reverse direction and cause it to tend to expand the body of the cap. In this way the cap is in part held from dislodgment except when taken hold of by the hand and pulled with sufficient force to overcome the gripping' tendency of the flange. ln this way the Harige forms a sealing` and gripping element. lts sealing function is to exclude moisture, dust and dirt from entering the cap and ultimately finding its way into the tube 6, as when the valve cap 9 is removed.
A further feature of my dust cap is the gripping wall formed along the interior from the point a to the point b. rl`he bore of the cap is such that it is normally slightly smaller than the diameter of the tube 6.
When forced over the tube it is slightly expanded which causes a faint bul ing of the wall from the point b inward. he resistance of the rubber to this action of expansion causes it to intimately hug the valve tube and thus add another gripping element for the retention of the dust cap in place.
The interior of the cap is further fashioned to receive the valve cap 9 by its bore corresponding in shape and size therewith. A shoulder 12 on the interior of the dust cap en ages the head of the valve cap and adds a rther retaining feature. As the dust cap is slipped on and off the rubber permits the shoulder 12 to yield and go in'past the dust cap.
It will now be seen that my improved dust cap comprises a hollow tubular or rubber body with a. sealing and` ripping flange, a gripping body portion, as between the points a and b, and a retainin shoulder, as at 12; that it is made of a rubber com ound which affords strength and toughness ut sucient elasticity to enable the cap to function in the manner I have described with respect to gripping and yet sliding 0H and on of the valve tube.
Having thus fully described my invention, what ll claim as new and desire to secure by Letters Patent, is
1. A rubber dust cap for pneumatic valve tubes comprising a. hollow body with a sealing and gripping Harige, said gripping dange lill@ being defined from the body of the dust cap by a slit extending outwardly from the bore of the dust cap toward its periphery, and a gripping body ortion.
2. A rubber ust cap forpneumatic valve tubes comprisingY a hollow body having a sealing and gripping lange inclined in position, said gripping flange being defined from body of' the dust cap by a slit extendingioutwardlyfrom the bore of the dust cap toward its periphery, a grippingbody portion andl a retaining shoulder. l l 3. A rubber dust cap for pneumatic valve tubes comprising a hollow body closed at one end and open at the other and having a gripping and sealing'lange near the open end ae its valve cap, of a rubber dust cap comprisdefined from the body'by a slit extending outwardly from .the bore of the body and being 'a bore normally less in diameter than* the valve tube to which it is to be .applied to form a gripping body portion when said portion is expanded by the forced entrance therein of the valve tube.
A. The combination with a valve tube and being ing a hollow body closed at one end, open at the other and having a sealin iange near the open end dened rom ythe body b a slit extending outwardly from the borel o the body and being formed With. a
and gripping hollow interior substantially' the counterl part of the valve tube andvalve cap, a part ping inclined Harige near the open end defined from the body by a, slit extending outy wardly from the bore of the body and being formed with its interior substantially a 'counterpart of Said tube and valve cap, the
normal diameter of a portion of the interior slightly less than the corresponding portlon of the valve tube and having a rev taining shoulder adjacent the valve cap.
ln testimony whereof ll allix my signature.
