AlR-VALVE.

SPECIFICATION- forming part of Letters .Patent No. 517,184, dated March 27, 1894.

Application filed .Tune 21, 1893.

To aZZ whom, it may concern:

Be it known that I, DAVID Ross BERRY, a citizen of the United States, residing at Rock- "away, in the county of Morris and State of New Jersey, have invented certain new and useful Improvements in Air-Valves, of which the following is a specification.

This invention relates to air valves adapted for use on vessels or chambers holding air Io under pressure, and which through the medium of the valve may be detachably connected to the source of air supply, when said vessel or chamber is being charged. The valve device hereinafter described is partic- 5 ularly adapted to be used in connection with pneumatic tires of bicycles.

In the drawings, Figure 1 is a sectional elevation of my improved valve device shown applied to` the pneumatic tire of a bicycle.

zo Fig. 2 is a sectional view of the valve and its case, detached. Fig. 3 shows the split clamping sleeve, and Figs. 4 and 5 are a plan and elevation, respectively, of the valve follower.

The valve case a has its bore a', valve seat a? and chamber a o a common axis. The interior of the chamber a is screw threaded and in this chamber is snugly fitted the corresponding screw threaded follower b, the upper end of which is provided with a knurled 0 head b', by means of which it is manipulated. This follower has a central bore and a valve seat 17 the lower part of the bore below the valve seat being enlarged to receive, and act as a guide for, plug c. This plugc has a Valve formed on its two ends and is of such a length that the upper valve is seated firmly in the valve seat of the follower b and the lower valve seated firnly in the valve seat of the case a when the follower b is screwed down 40 in the chanber a as shown at Fig. 1. From the upper end of the plug c extends a rod or stern c', which passes through, and is somewhat longer than part of the central bore of the follower b above the valve seat 27 This 5 stern is provided with a button or flange c a little larger in diameter than the bore of the follower. By this arrangement the plug c is Suspended with its valves away from the valve seats a? and b when the follower b is partly nnscrewed from the 'charnber a as shown at Fig. 2, and this is the arrangement of the parts of the device When the tube or Serial No. 478,327. (No model.)

chamber to which it is attached is being charged or infiated with air, the coupling or connection of the source of air supply then being fitted on the case a by its external screw thread.

To provide for the air passing freely through the device, slots ?9 b are formed in the top of the follower b, opening into the upper end of the bore, and slots b b transversely formed through the lower part of the follower, extending therein nearly to the valve seat 6 Now upon the removal of the air compressor or the coupling of the source of air supply, 6 the pressure in the tube or chanber, inflated forces the plug against the seat 6 thereby preventing escape of air, both valves then being firmly closed by screwing down the folx lower b, as before described. From the sides of the plug c project pins 0 0 which extend into the slots b b of the follower b, and so cause the plug to be rotated with the follower.

d is a cap for excluding dirt, &c., from the interior of the device.

The means here adopted for securing air Valves to the tires of bicycles or toother-flexible connections of other air chambers, consists of the grooved neck or coupling & of the Bo Valve case a, adapted to be inserted in the tubular neck e of the elastic tube e' the screw threaded sleeve f having a smooth bore to fit over the tubular neck e and provided with slits f' f', and the nut g fitted to turn on the screw thread of the sleeve f, said screw thread being cut deeper at its upper end or made taper in form, so that the nut g, when forced down on the sleeve will contract it and cause it to press the tubular neck e tightly against the grooved coupling a To fasten the elastic tube e' to a metal tire h of a bicycle, the lower end of the sleeve` f is formed with a fiange f The sleeve passes through a hole in the tire h and said tire is 9 5 clamped rigidly between the flangef and nut Or where a covering 'i is used to protect the elastic tube e', the fiange f of the sleeve then presses the edges of this covering against the metal tire h, when the nut g is screwed Ioo home, and at the time the tubular neck e is clamped between the sleevef and the grooved coupling pipe 60 I claim as my invention- 1. The combination of the valve holding device having a grooved coupling neck, adapted to be inserted in a flexible tube, a screw threaded sleeve, anda tightening nut.

2. The conbination of the valve holding device havinga grooved coupling neek, adapted to be inserted in a flexible tube, a split taper screw threaded sleeve, and a tightenng nut.

3. The conbination of the valve holding device having a grooved conpling neck, adapted to be inserted in a fiexible tube, a plate or frame through which the fiexible tube passes, a flanged screw threaded sleeve, and a tightening nut for securing the flexible tube and the valve holding device to the plate or frane.

4. The conbination of the valve holdin g device having a grooved coupling neck, adapted to be inserted in a flexible tube, a plate or frane through which the fiexible tube passes, a fianged split taper screw threaded sleeve, and a tightening nut for securing the flexible tube and the valve holding device together, and to the plate or frane.

5. The combination of the valve case having ascrew threaded exterior and a central chamber and bore and a valve seat forned therein, a cylindrical plug, having a valve formed on its end, a follower serving as a plug to close said chamber and having a central bore to guide and control the valve plug, and adapted to force and hold the valve against its seat, and a Gap screwing upon the exterior thread of the case.

6. The combination of the valve case, having a central chanber and bore and a valve seat forned therein, a cylindrical plug, having a valve formed on each of its ends, and a follower having a valve seat and a central bore to guide and control the valve plug and adapted to force and hold the Valves against their seats.

7. The conbnation of the valve case having a central chanber and bore, and a valve seat formed therein, a cylindrical plug, having a valve formed on its end a follower having a central bore to guide and control the valve plug, adapted to force and hold the valve against its seat, and a sten projecting from the valve plug through the follower, and having a button or flange on its upper end.

8. The conbination of the valve case, having a chanber and bore and valve seat forned therein, a screw threaded follower in the chamber of the valve ease having a central bore and transverse slots at its lower end, a plug with a valve forned on its end and having guide pins arranged to work in the transverse slots of the follower.

9. The combination of the valve case, having a chamber and bore and valve seat formed theren, a screw threaded follower in the ehanber of the valve case, having a central bore, a valve seat, and transverse slots at its lower end, a plug with a valve formed on each of its ends, having guide pins arranged to work in the transverse slots of the follower, and a stem projecting from the valve plug through the follower and having a fiange or button on its upper end.
