UNITED STATES PATENT OFFICE.
EUGENE V. MYERS, OF EAST ORANGE, NEW JERSEY, ASSIGNOR TO A. SCHBADERS SON,
INQ, OF BROOKLYN, NEW YORK, A OORPORATION OF NEW YORK.
TIRE VALVE.
- Driginal application filed May 21, 1917, Serial No. 169,846; Divided and this application filed April 6,
i 1922. Serial No. 550,203.
6 sex and State of New Jersey, have invented certain new and useful Improvements in Tire Valves, of which the following is a specification.
This application is a division of my appli- 'lo cation filed May 21, 1917, Serial No. 169,846.
This invention relates to tire valves or similar devices and aims to provide certain improvements therein,
Valves forpneumatic tlres usually comprlse a long casing member commonly called a valve stem which is provided with a bore from end to end. The maximum diameter of such casings is limited dueto the condition that the valve must pass through a hole in 2 the vehicle rim, and such hole is limited in size. Hence the internal bore must necessarily be of small dimensions. In those constructions wherein the valve casing is provided with a reduced nipple at its inner end the diameter of this bore is. still further limited.
Within the core is usually located a valve seat and a valve plunger, together with a spring for operatin the plunger, and these inserted within the bore by screwin them in.
The valve casings as thus descri ed have almost invariably been made of brass owing to the fact that the valves, in use aresubjected to wet and moisture and would speedily rust if not formed of a non-rusting metal. It is particularly desirable that the inner parts of the valve casing and particularly the portions near the inner end shall be rust-proof, since it is at these portions that the actual working parts of the valve are located. V
The most expensive parts of the'valve is the casingand it materially increases the cost thereof to construct it of solid brass or other expensive non-corroding metal. The object of the present invention is to reduce the cost of the casing.
According to the resent invention the cas-- ing may be form of brass, or other maymade separately and.
having thin walls, so that a large saving in metal is obtained. According to the invention the valve spring-holder seat within the casing is formed separately from the casin In the accompanying drawing whic shows a'longitudinal-section of a valve casing embodying my invention, let A indicate the valve casing which consists of the shell B constructedof brass or other rust-resisting material and preferably formed from a suitable blank by a series of drawing and rolling operations.
The shell is formed at one end with the conventional internal thread D and tapered shoulder E and at the other end with a suitable foot F for receiving an inner tube. To support the lower end of working parts or valve insides I provide a member C which may be formed of any suitable material and may be held in place within the shell below the top thereof either frictionally, by indentations G or by any other means. Said member is formed with a seat H to receive and support a valve spring-holder which constitutes one of the elements of a standard valve inside. If it is desired to use the member C solely as a valve spring-holder seat it will be understood that said member need not have the tubular formation shown in the drawing but may take any appropriate shape which will answer the intended purpose. Preferably, however, the member is shaped as shown to constitute a guide for the insertion of the valve inside. 1
While I have shown and described a preferred embodiment of my. invention it will be understood that I do not wish to be limited thereto since various changes may be made therein without departing from the spirit of the invention.
What I claim is:.
1. A'valve casing comprising a drawn shell-having a separately formed internal valve spring-holder seat therein and held by the wall of the shell between its ends.
2. A valve casingcomprising a drawn shell havin an internally threaded end and an integra seating shoulder below said thread, and a separately formed valve spring-holder seat: within'said shell below said shoulder.
In witness whereof, I have hereunto signed my name;
