VALVE FOR iNFLATIoN.
SPECIFICATION forming part of Letters Patent N o. 672,271, dated April 16, 1901.
Application filed August 28. 1900. Serial No. 28,323. ING model.)
p T0 @ZZ whom it may oon/cerro.
Be it known that I, ROLAND C. HILTON, 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 Inlation, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention has for its objects the production of simple, reliable, and inexpensive devices to facilitate the inflation of articles, particularly pneumatic tires, and the prevention of the removal and often the loss of the cap of the device, said cap being in this construction permanently secured and clenched to the body of the device carrying the valveseat, although well adapted to be revolved around the head of said body, as shown in the accompanying drawings, in Which- Figure 1 represents, on an enlarged scale, a longitudinal central section of the parts of the device with the central hollow plug lowered a short distance away .from the bottom ot' the head of the valve-stem as it is during the process of inflation. Fig. 2 is also a longitudinal section of the device, showing the upper portion of the hollow plug in section, its middle portion being in elevation to show the left-hand th read thereon and its lower portion quadrangular and received loosely in engagement with the corresponding four walls of a chamber within the device, the upper end of said plug being forced under the head of the valve-stem to lock the valve on its seat after inflation has been made. Fig. 3 is a transverse section on line oof Fig. 2. Fig. 4. is a longitudinal section of a modification having substantially the same arrangement of internal parts shown in the other figures.
In said drawings the casing or body H, Figs. l and 2, is generally secured within a short rubber tube attached to a hollow rubber tire and is generally provided with annular grooves h in its periphery to increase the adhesion of said short tube thereto. Said body H is outwardly cylindrical and has therein two superposed chambers. The upper chamber has its upper portion d cylindrical; but the lower portion e is polygonal, preferably quadrangular, to receive a correspondinglyformed plug E, the quadrangular portion preventing the latter from rotating while being elevated or lowered by the cap A. The lower chamber G contains the valve F and a coiled spring g of light wire, the latter having its lower end bearing upon the in wardly-flanged lower end of the body H and its upper end bearing against the bottom of the valve F. The re silience of the springis only slightly stronger than necessary to carry the weight of the valve-stem and valve, so that the latter is normally bearing against the seat or the packing o', carried by the body H, but not strong enough to prevent the valve-stem and valve from being pressed down by the jet of air sent down by the air-pump while its piston is forced downward; but the spring g causes the valve F to act as a check-valve while the pumps piston is ascending for a new stroke.
The valve F ts loosely within the chamber G, so that air can pass around it to the object intended to be inflated. For the same purpose its stem f, which is preferably integral therewith, fits loosely within the body H and within the plug E. The upper portion d of said plug is screw-threaded, preferably with a left-hand thread, so that when the righthand screw-nipple, generally found on the outer `end of a pumps hose, is connected with the cap A the latter will have no tendency to release the valve from its locked position until said nipple is wholly secured to the cap A, after which two or three right-hand turns of said cap and nipple together will release the valve-stem to the position shown in Figs. l and 4l. The upper end of the valve-stem f has a head f2, by which the valve is pulled up against its seat when the cap A is rotated toward the left side, which lifts the plug E to the position shown in Fig. 2. The under side of the head f2 or the top of the plug E has radial serrations to permit the passage of air between them at any time.
To prevent the cap A to be detached from the valve-seat carrier or body H and possibly be lost, said cap is revoluble, but permanently secured to said body H. For this purpose said body has a laterally-projecting head 2 and the cap has an inwardlyiianged lower end 3, which is made to engage with the under side of said head.
IOO
In the modification shown in Fig. 4 the cap permanently attached to the valve-seat body is applied to the kind of valve for inflation which is clamped to the Wall of a tire between a broad inner flange 4 and a nut 5 and possibly some washers. To secure the screwthreaded tube 6 to the valve-seat carrier, the latter is provided with a collar 7 at a short distance below the head 2, and a thilnble 8 is made to surround the collar 7 and has its upper edge flanged inwardly thereon. Within the thimble is placed a packing-ring 9, and under it the thimble is screw-tapped for engagement with the upper portion of the screwthreaded tube 6, and said tube and thimble may be additionally soldered or brazed together.
Having now fully described my invention, I claiml. In a Valve for inflation the combination of a chambered body carrying a valve-seat and having a laterallyprojecting head, a screw-threaded plug partly within the chamber of said body, a valve adapted to bear on the valve-seat and having its stern passing loosely through the plug, and a cap internally screw-tapped to engage the plug and having its lower end embracing the head of the chambered body and permanently secured thereto substantially as described.
2. The combination of a chambered body carrying a valve-seat and having a laterallyprojecting head, a screw-threaded plug having its lower end polygonal, a valve adapted to bear on the valve-seat and having its stem passing loosely through the plug, and a cap internally screw-tapped` to engage the plug and having its lower end loosely embracing the head of the chambered body and permanently secured thereto substantially as described.
3. The combination of a chambered body carrying a valve-seat and having a laterallyprojecting head a screw-threaded plug partly within the chamber ot' said body, a valve adapted to bear on the valve-seat and having its stein passing loosely through the plug, and a cap internally screw-threaded for screw devices having different-diameters, the outer one being oflarger diameter than the inner one to engage the plug, said cap having its lower end permanently secured to the chambered body substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
ROLAND C. HILTON.
