CAP FOR VALVE STEMS.
APPLICATION FILED NOV. 24,1919.

UHTED STATS HENRY BRENNER, OF NEVI YORK, N. Y.
CAP FOR VALVE-STEMS.
Application filed November 24, 1919.
T 0 all w 710m it may concern:
Be it known that I, HENRY BRENNER, a citizen of Hungary, residing in the borough of Manhattan, city of New York, county of New York, and State of New York, have invented certain new and useful Improve ments in Caps for Valve-Stems, of which the following is a specification.
My invention relates to caps for tirevalves, and more particularly relates to that type of dustproof and waterproof cap that is adapted to be readily slipped on and oil the tirevalve, thus avoiding the well known annoyances and difliculties often encountered in the laborious operation of screwing and unscrewing the cap on the valve, particularly after the valve has been in use for some time.
An object of my invention is to produce a cap for the above described purpose that is simple in construction and inexpensive to manufacture.
Further objects are the production of a. cap that is highly eflicient in use and easy to adjust.
Still further objects and advantages will hereinafter appear from the following description.
I will now describe an embodiment of my invention illustrated in the accompanying drawing and will thereafter point out my invention in claims.
In the drawing, Figure 1 is a side elevation of a cap for tire-valves embodying my invention.
Fig. 2 is a similar view partly in central vertical section as viewed from the right in Fig. 1.
Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2.
In the drawing, I have shown the embodiment of my invention as applied to a stand ard type of valve-stem, although it will be seen that my invention is adapted to various types of valve-stems.
The embodiment of my invention illustrated in the drawing consists of a cap 1 fitting over the usual tire valve-stem 2. The stem 2 has the usual air-inlet 8, and is provided with the usual arcuate threaded portions interrupted by two flat portions on opposite sides of the stem, and is shown as fitting into the felly 5 of the wheel. The nut Specification of Letters Patent. Pat gntqgfl Iflay 31, 152i Serial No. 340,345.
4 holds the stem 2 in fixed position on the felly 5. A rubber washer 13 is fitted over the stem 2.
It has been customary heretofore to provide dust-caps for tire stems, and such caps are usually screwed on the mlve-stem. This has been a laborious operation with new stems and after the stems have been in use for some time and the threads worn or corroded, great difficulty has been encountered in getting the caps on and on the valve stems. To overcome this difiiculty I provide a cap 1 that readily slips over the valvestem and locks in place at any d sired position. This cap 1 has an annular flange 6 at its lower or open end, forming a chamber for the locking means for holding the cap on the Valve-stem. The flange 6 has fitted into it, anupper washer 11, a lower washer 12 substantially of the shape and size of the interior of the flange 6, and a sliding washer 7 between them. The washer 7 is somewhat smaller than the washers 11 and 12 and is adapted to slide in the chamber as hereinafter described. The bottom of the flange 6 and the three washers contained therein have central openings having two opposite sides flat and the other opposite sides arouate, corresponding to the shape of the valvestem, and adapted to fit substantially snugly around said valve-stem. The opposite flat sides of the washer openings corresponding to the flat sides of the valve-stem prevent the turning of the cap on the valvestem. A stud 1 1 having a button 15 at its end is formed on the side 8 of the washer 7 and projects through an opening in the flange 6. A block of rubber or other suitable elastic material is inserted in the flange 6 between the washers 11 and 12 and at the end of the washer 7, opposite the stud 14; and button 15. The side of the opening of the washer 7, opposite the stud 14, is wedge shaped forming a tooth 9 adapted to enter into engagement with the threads on the valve-stem 2.
Normally, when the cap embodying my invention is offthe valve-stem, the block of rubber 10 presses against the washer 7 and pushes its central opening out of alinement with the openings in the washers 11 and 12 and the opening in the bottom of the flange 6. To fit the cap 1 over the valve-stem 2, the button 15 is pressed in, forcing the washer 7 against the rubber block 10 until the central Openings are all in alinement. The cap is then slipped over the valve-stem 2 until it strikes the rubber washer 13, and the button 15 is released. The rubber block 10 immediately pushes the washer 7 over until the tooth 9 in its central opening engages with one of the threads on the valvestem 2, which engagement locks the cap in place on the valve-stem. The fiat walls on the valve-stem and the corresponding fiat sides of the washer 7 prevent the cap from turning on the valve-stem. To remove the cap from the valve-stem, the operation is reversed, that is, the button 15 is again pressed in, forcing the washer 7 against the resilient block 10, until the tooth 9 is out of engagement with the threads on the valvestem 2, and the cap is pulled off the valvestem.
It will be seen that the cap embodying my invention consists of but few parts and presents a smooth exterior surface that can be easily cleaned, and provides no place for dirt, dust or moisture to collect;
It is obvious that various modifications may be made in the construction above particularly described within the principle and scope of my invention.
I claim: 7 I
1. A cap for valve-stems, consisting of a casing closed at one end and open at the other, a chamber at the open end, such casing and chamber adapted to slide on and off a valve-stem, a sliding washer contained in the chamber having an opening adapted to fit over the valve-stem, a stud on one side of said washer projecting through the chamber, and a resilient block in the chamber at the opposite side of the washer adapted to bring the washer into engagement with the valvestem, when the cap is on the stem.
2. A cap for valve-stems, consisting of a casing, a chamber at one end ofthe casing, a sliding washer contained in said chamber having an opening adapted to fit over the valve-stem, and resilient means consisting of a block of rubber for bringing the sliding washer into engagement with the valvestem. I
In testimony whereof I have aiiiXed my signature to this specification.
