Application filed June 15, 1910. Serial No. 566,923.
To all whom it may concern.
-Be it known that I, FREDERICK M. NEAL, citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Air-Valves for Pneumatic Tires; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in air valves for pneumatic tires, and'it consists in certain details of constructioil to be more fully set forth in the follpwing specification.
Referring to the drawings: Figure 1 represents the device assembled; Fig.4 2 is a central sectional view of Fig. 1; and Fig.3 is a detail broken view, partly insection, of the valve controller.
. Like reference figures indicate like parts throughout the several views.
The exteriorly threaded tube 1 has the usual head portion 2 adapted to be inserted in the-interior of a' pneumatic tire (not shown) and the usual clamping mi:- 3 to nnaintaih the tube thereto. The integrally constructed valve controller comprises the elongated valve mounting 4, the interiorlythreaded cap 3 and the threaded dust cap end 4.
5 is the valve rod carrying on its inner threaded end the removable valve 6. 7 is a small air passage in the end of the valve mounting through which the valve rod passes, and 8 is a chamber of greater-disarm eter than the passage 7 and adapted to receive' the spring 9 located between the innor end of said chamber and the thin wings 5 of the valve rod. This spring is adapted to maintain the valve normally against its seat at the exterior of the inner end of thevalve mounting, as shown at Fig. 2. The interiorly threaded cap portion of the controller is screwed on to the end of the casing l and. an air-tight connection between the cap and casing is efiected by means of the packing 10.
The dust cap 11 ismounted on the threaded end 4* of the controller and it has the projection 11 adapted, when the said cap is removed, to engage the end of the-valverod and force the valve from its seat to partially deflate a tire; but when, ,as is frequently the case, it is necessary to fully deflate a tire, this method would occupy too much'time, therefore, to quickly and completely exhaust the air from a tire, all that is necessary is to detach the controller enltirely from the casing when the air will have free exit through the passage 12 andchamber 13 of the casing.
To inflate a tire, the dust cap is removed and a pump connection attached to the threaded end 4* and the pressure of air will force the valve from its seat as shown at Fig. 3. Now, as the spring must necessarily be very light and sensitive, it would be crowded or packed into thebottom of the chamber 8 andthus have a tendency to choke up the narrow passage 7 and obstruct the free passage of air time through were it not restrained by the wings 5" of the rod engaging the shoulder 14- as shown at Fig. 3i lhese wings are very thin, so as to leave plenty of resin for the air to pass and may be formed from the body of the valve rod .or secured thereto and at such a position on the rod that will enable the valve to be forced from its seat a distance suflicient to afi'ord airee exit for the air through the opening ,9]? port '3 and without choking said port. i V
The simplicity and utility of the device as above described will be apparent to tire users. It is of frequent occurrence for dirt tit Ill
to lodge on the face of the valve and thus cause a leakage, and it is difficult with some constructions to get at and remove the trouble. Some users of tires inject fluids or semi-fluids into tires to close punctures, which always clog the valve mechanism and. thus hinder rapid defla ing. and inflating; but with the above cor struction the con troller can be instantly-removed and the trouble quickly eradicated or a new valve attached'without unnecessary delay. To re move the valve all that is necessary is to engage the slotted end 15 of the dust cap with the key 16 at the outer end of the valve rod and thus hold the rod againstturning while the valve is screwed or unscrewed from said rod.
Having thus described my invention, what I claim is:
In a valve of the class described, fi;hecorn'- prising an elongated valve mounting having an air port in its inner end and internalchamber communicating therewith, the valve mounting having at its outer end a dust-cap extension, a valve rod arranged in the chamber of said valve mounting, the inner endv of said rod projecting through said air port, and its outer end projecting into the dust-cap extension, a removable valve screw threaded on the inner projecting end of said rod and seating against the extenor of the valve mounting, means for limiting the opening movement of said valve,
a spiingasso ciated with the valve rod for maintaining said valve normally seated, a
key arranged at the outer extremitv of the valve rod, and a cap carried by the dust- 15 cap extension and provided with a slotted projection adapted to cooperate with sald key to hold the valve rod against rotation FREDERICK NEAL;
