ROBERT E. HENEMIER, on NEW YORK, N. Y.
TIRE-VALVE ALLOY.
Patented July 20, 1915.
1 147 398 Specification of Letters Patent. No Drawing.
To all whom it may concern:
7 Be it known that I, ROBERT H. HENEMIER,
and resident of A citizen of the United States, New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Tire-Valve oys, of which the following is a specification.
"The object of my invention is a tire valve alloy particularly adapted for economy in construction, great strength, power, and capable of resistance to the corrosive efiects of water, oil and vulcanized rubber.
A further object of my invention is a valve capable of being die cast. For an article of this character die casting results in great economy of manufacture. Heretofore it has been impossible, owing to the failure of the metal used, to attain all the above functions.
In order to be air tight, the casting must be structurally dense. That is, it must have such a close grain when cast as to be free from blow holes or pores,not only to hold in the ordinary pressure of air within the tire but those extra pressures due to the sudden blows upon the tire when it strikes the road. other requisite of my invention is that it-shall have tensile strength to withstand the pressures above referred to and to with stand the rough usage to which tire valves With the metal heretofore used for die casting an ordinary wrench would sever the valve when it was screwing the clamp nut into place. 'e casting therefor must be in this respect and supply an article which has such tensile strength as to resist the destructive tendencies of monkey wrenches. Such a die casting further must resist the corrosive action of water since itis so frequently and for such long periods exposed to' the action of the elements. Furthermore, chemical action of air, and of oil which is apt to fall upon the valve either from the machine or from modern road beds. It must also resist the action of vulcanized rubber for it is rubber with which it is in constant contact where "it is attached to the wheel. A failure results in leaks, and damaged valves and tubes. For this sistsof a valve having any desired construction and composed of an alloy of aluminum it must resist the to meet this test reason, my lnvention con- Application filed January 4, 1915. Serial No. 489.
and nickel. Copper ma be added to the alloy and improve its ensity and tensile strength. The nickel assists in protection from the elements and hardens it. The aluminum supplies light weight, ductility and a binder for the other elements in'the alloy. I preferably use between 5% and 15% of nickel, between 75% and 85% of aluminum, and between 7% and 10% of The mixture of these amounts of made in the melting pot whence it is driven under pressure into dies adapted to mold the alloy into its final shape. This step of th casting.
By using the proportions of the metals as above set forth I secure an alloy which has all the properties necessary for success: ful use in a valve stem, particularly when used in a pneumatic tire. These proportions produce an alloy having suflicient density, tensile strength and workability so that the stem may be when complete is impervious to air under pressure and will stand rough handling without breakage or distortion. q
at claim is;
e process is well known in. die
readily machined and 1. An alloy of aluminum, nickel and copper containing from about seventy-five 75) per cent. to about eighty-five percent. of aluminum, about five (5) per cent. to fifteen (15) per cent. of nickel and from about seven (7) per cent. to ten (10) per cent. of copper.
2 As a new article of manufacture, a tire valve stem composed of an alloy of aluminum, nickel and copper wherein the aluminum content composes the major portion thereof the aluminum content being less than 85%.
3. As a new article of manufacture, a tire valve-stem composed of an alloy of alumiabout seventy-five (75) per cent. to about eighty-five (85) per cent. of aluminum, cent. of nlckel and from about seven per cent. to ten (10) per cent; of copper. York and State of New York this 9th day of October A. D. 1914'.
