DUST EXCLUDING DEVICE FOR VALVE'STEMS.
Application filed. January This invention relates to dust excluding devices for valve stems and more especially to that type in which the dust cap permanently and loosely" connected with the valve stem.
An object of the invention. is to guard against loss of the dust cap.
Another object is to provide a construction that will facilitate capping and uncapping the valve stem as is necessary when a pneumatic tireis to be inflated.
A further object is to provide a construc tion which will necessitate the movement of the cap in two directions at right angles to each other in the opening and closing move ments of said cap.
Qther objects and advantages will. appear in the subjoined detailed description,
Theaccompanying drawings illustrate the invention.
Figure 1 is a side elevation of dust excluding device constructed in accordance with the provisions of this invention, the valve stem on which the device is mounted and the valve stem cap being indicated in broken lines. The dust cap is shown in open position in solid lines and is shown in a mid-closed position in dotted lines.
Figure 2 is an elevation oi? the device shown in Fig. 1, said device being shown rotated slightly to the. left on its axis from the position shown in Fig. 1. The dust cap is in closed position.
Figure 3 is a plan view of Fig. 2.
Figure 1 is a sectional elevation of one of the members of the device.
Figure 5 is a sectional elevation of the other member of the device.
Figure 6 is an inverted plan section on the line indicated by 6 6, 1.
Figure 7 is a plan section on the line in.- dicated by 7--7, Fig. 1, on a larger scale.
Two members are provided, a tubular body 11 and a cap 12, which is permanently and loosely connected with the body 11. To effect the connection the member 12 isprovided with inwardly projecting bosses 13 adapted to slide in slots'formed in the body 11. Each slot comprises a portion 14 extending lengthwise of the bod v and another JOllJlOIl 15 extending transversely oi said body. Preferably, the slot portion 15; is asla-nt downwardly away from the slot portion 1d, like a right hand screw thread.
The bosses 13 are formed at the lower ends of arms 16 that constitute portions of the 9, 1926. Serial No. 80,148.
The slot 141, 15 need not be an open slot and is preferably formed by a pressing op,- eration, the metal being pressed inwardly so as to form a groove or channel in which the bosses 13 ride.
The body 11 isprovided with an internally threaded portion .19 adapted to be screwed onto the valve stem, which is indicated in Fig. 1 in broken lines 20. The valve stem 20 isprovided with the usual valve stem cap 21 Which primarily serves to insure against leakage of air and protects the valve, not shown, from dust. The'dust cap 12 is an additional safeguard against the entrance or" dust to' the interior of the valve stem. p
The arms 16 are of sufficient length so that when the bosses 13 are at the, upper ends or the slot portions 14 and the cap 12 is axially aligned with the body 11, the tubelar portion 17 of the cap 12'will'clear the valve stem cap 21, thus enabling the cap 12 to be swung from its axially aligned position downwardly to the open position shown in Fig. 1 in solid lines.
To close the cap 12, the same will be moved upwardly from the position shown in solid lines in Fig. 1 with the bosses 13 at the upper ends of the slot portions 1 1 and with the cap axially aligned with the body 11, as shown in dotted lines in Fig. 1, and then the cap 12 will be forced downwardly, thus moving the bosses 13 to the lower ends of the slots 1 1. The cap 12 will then be turned clockwise to cause the bosses 13 to ride into the slot portions 15, as in Fig. 2.
Preferably, the upper end of the body 11 is slightly reduced, as indicated at 22, and the inside diameter of the tubular cap portion 17 is slightly less than the outside diameter of the body 11 below the reduced portion 22, thus entailing that thebody 11 will wedgedly engage and slightly telescope within the cap'portion 17. lVhen the members 11, 12
are thus wedgedly engaged, the bosses l3 ride against the upper walls of the slot por-,
Preferably, the lower end of the member 11 is in the form of a nut 28 adapted to engage the inner face of the wheel felloe or a washer that may be positioned between the felloe and the nut 23.
To open the cap 12, it will be raised from the position shown in Fig. 2 until the cap portion 17 clears the cap 21and the cap 12 will then be swung laterally and allowedto drop to the position shown in solid lines in Fig. 1. Then the cap 12 is thus in open position, the cap 21 may be removed and the air nozzle applied to the valve stem in the usual manner so as to inflate the tire, not shown, with which the valve stem is connected.
It is to be understood that the bosses 13 constitute a form ofprojection and that the projections and the grooves 14, 15 together constitute one form of means slidably and pivotally connecting thecap and body and that such means may be otherwise constructed within the scope of the invention as expressed in some of the appended claims. It is evident that the connection means could be a reversal of that illustrated so that the grooves 14, 15 would be in the cap and the bosses 13 on the body. The connection means shown and described permit the cap to be axially aligned with and engage the body when the cap is in the closed position shown in Fig. 2 and to be moved endwise to and from the intermediate position shown in broken lines in Fig. 1 and to be moved angularly to and from the open position shown in full lines in Fig. 1.

1; A dust excluding device comprising two members, one of said members having a groove and the other member having a projection to ride in the. groove, said groove having a portion extending longitudinally of the member and said groove having a portion extending laterally from the first mentioned groove port-ion, one of said members being tubular and adapted to be secured to a valve stem and the other member forming a cap adapted to engage one end of the tubular member when the projection is in the laterally projecting portion of the groove.
2. A dust excluding device comprising two members, one of said members having a groove and the other memberhaving a projection to ride in the groove, said groove having a portion extending longitudinally of the member and said groove having a portion extending laterally from the first men tioned groove portion and aslant therefrom, one of said members being tubular and adapted to be secured to a valve stem and the other member forming a cap adapted to engage one end of the tubular member when the projection is in the laterally projecting portion of. the groove.
