FREDERICK L. SOWVLE, OF NEW BEDFORD, MASSACHUSETTS VALVE FOR INFLATION.
SPECIFICATION forming part of Letters Patent No. 660,128, dated October 23, 1900.
Application filed March 2, 1900. Serial No. 7,101. (No model.)
To all whom it may concern:
Be it. known that I, FREDERICK L. SowLn, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts,have invented certain new and useful Improvements in Valves for Inflation, of which the following is a specification, reference being had therein to the accompanying drawings. v
The invention has for its object the production of simple, reliable, and inexpensive devices to facilitate the inflation of articles, particularly pneumatic tires, the device consisting principally of two parts, one being socured to the object to be inflated and the other a controller adapted to be secured either to the first part or to the inflater.
This invention consists mainly in the peculiar means employed to adapt the second or outer part to open and close the valve at the lower end of the first or inner part of the device when desired and to the ball checkvalve located within the hollow plug of the lower valve above the latter, as shown in the accompanying drawings, in which- Figure 1 represents, on an enlarged scale, a longitudinal central section of the outer and inner parts of the device coupled together as during the process of inflation. Fig. 2 is a side view of the inner part of the device, showing the inner plug partly lifted from its seat, with the upper vent-hole open and exposed. Fig. 3 is a transverse section on line as a; of Fig. 1, showing the square head of the plug-valve and the square socket therefor in the outer part of the device. Fig. 4=is a side view of the plug-valve, all the figures being on an enlarged scale.
In said drawings, A represents the tubular casing of the outer part of the device, havingthe upper end of its periphery provided with serrations 1), adapted to be received and retained within one end of a rubber hose leading to an air-pump.
The interior surface of the lower portion of the casing A is screw-tapped, and above said portion said interior is of much smaller size and has a central perforation c of polygonal form, preferably square, to receive, guide, and control, as a watch-key, the correspond- .ing square head e of a valve-carrying plug E,
located within the inner part of the device.
The plug E is hollow and has two superposed chambers of different diameters. The upper chamberf is the narrowest and constitutes a passage for the air used during inflation and has an opening f leading on the side into its upper end.
The lower chamber g has in its lower end an opening g leading from its side into the interior of the tube H. Within the cylindrical chamber 9 there is a ball 6, capable of moving freely therein, being'ofsmaller diameter than the chamber g, but of larger diameter than the chamberf, and at the junction of said chambers there is a conical valve-seat k for the ball t, which ball serves as a checkvalve for the device. The lower end of the plug E is. screw-tapped internally and has in engagement with its screw-thread a metal disk Z, which closes the bottom of the chamber except its opening 9 above said disk. Bearing against the disk Z there is in the bottom of the plug E a yielding washer c of leather or of rubber, to rest upon the valve-' seat it within the bottom of the chamber of the tube H.
At the upper end of the square perforation c the interior of the casing A is preferably cylindrical at 0 as it is easier to drill a cylindrical passage for the air but there is kept an air-passage between the square head e of the valve-plug and the walls of the square perforation c.
The inner part of the device consists of the tube H, the upper end of which is screwthreaded externally with a right-hand thread to enter into engagement with the screwtapped interior of the casing A, and the interior of said tube H is screw-tapped with a left-hand thread to receive the left hand thread of the plug E, so that when the outer part, having the casing A, is placed and rotated into engagement with the right-hand screw-thread of the inner part H its square perforation c engages the square head e of the plug E and rotates it toward the right; but said plug, having a left-hand. thread, causes it to be partly lifted and unscrewed from the tube H and lifts its washer e from contact with the valve-seat h in the bottom of said tube, opening the device for the passage of air from the air-pump. A similar result would be attained if the interior of the too casing had a left-hand thread and the plug E had a right-hand thread, being only a reversal of location of the right-hand and lefthand threaded parts.
Having now fully described my invention, I claim 1. In a valve for inflation the combination of a tube havinga valve-seat in its lower end with a casing engaging the upper end of said tube, and within said tube a partly-hollow screw-valve having an angular stem engaging in an angular perforation in said casing, the plug of the screw-valve having two superposed chambers of different diameters and a valve-seat between them, with a ball check valve in the widest chamber above the lower valve substantially as described.
2. The combination of a casing having internally a polygonal sockeuwith the tube H, having externally a screw-thread inclined in one direction and internally a screw-thread inclined in the opposite direction said tube having a valve-seat in its lower end with a valve-plug E, externally screw-threaded to fit the interior screw-thread of the tube H, said valve-plug having a polygonal head and internal chambers, with a ball check-valve in the lower chamber above its lower closure and its yielding washer substantially as described.
In testimony whereof I afiix my signature in presence of two witnesses.
