PAUIIJ. GREBEL AND WILLIAM J. TI-IEIS, OF CHICAGO, ILLINOIS, ASSIGNORS TO MANU- FAC'I'URERS EQUIPMENT COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

AIR-VALVE To all whom it may concern:

Be it known that we, PAUL J. GREBEI. and \Vnmmn J. THEIS, citizens of the United States, and residents ofthe city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Air-Valves; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a valve for controlling the supply and exhaust of the motive fluid to and from the working cylinders.

The object of our invention is to provide a simple, durable and efficient device of the kind described, and to this end our invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 illustrates a side elevation of a device embodying this invention. Fig. 2 shows an end elevation shows an elevation of our device operatively attached to a friction driven countershaft for controlling the operation of the friction mechanism of the a view similar to that shown in Fig. 4, showing the parts in operation. F1" 6 1s a View of a modified construction embodyingv this invention. Fig. 7 is a section taken through one of the' valve casings at substantially right angles with Fig. 4, and showing parts in elevation. Fig. 8 1s a section taken on line 88 of Fig. 7. Fig. 9 is a section taken on line 99 of Fig. 7.

As. shown in the drawings: 1, indicates connected casings, the interior of each of which is divided into three chambers 2, 3, and 4, by transverse partitions and 6, each of which is provided with a central opening. The inlet-chamber 2, is provided with a plurality of openings 7, communicating with an annular passage 8, which is in turnconnected by a duct 9, to.a fluid supply pipe 10. The intermediate chamber 3,-is connected by a suitable pipe 11, to the working cylinder or other mechanism, the operation of which it is desired to control by the operation of my device. The outletchamber 4, is provided with anynumber of suitable exhaust ports 12.

Specification of Letters Patent.

Application filed November 22. 1909.

Patented Dec. 13, 1910. Serial No. 529,484.

A freely movable valve stem 14, is position'ed within the casing having on opposite ends thereof heads -16, which are adapted to seat on opposite sides of the partitions 5.(i respectively. A washer 17, of suitable packing material, such, for example, as leather or rubber is provided for the inner face of each of the valves 15 and 16, to insure a fluid tight closure when the respective valve is seated.

The valve stem H, is corrugated longitudinally to permit free passage of air from one chamber to the other at the proper time.

Any suitable operating mechanism may be provided to force the closure inwardly to force the valve 16, on its seat to close communication between the exhaust chamber 4, and chamber 3 and to force the valve 15, from its seat to open communication between the inlet chamber 2 and chamber 3. As shown, for this purpose a stem or shank 18, is provided which extends through a sleeve 19, provided with an enlarged chamber in its outer end and which is secured to the valve casing by a cap screw 50. A spring 20, is engaged in the chamber in the sleeve around the stem and bears against the enlarged head18, of the stem and normally acts to force the stem to its outer limit of movement out of engagement with the valve 16.

A bracket 25,.is provided integral with the'casings 1, on which are pivoted levers 26 and 27, one for each stem and each of which is provided with notches or seats 3637. A standard 33,-is secured to the bracket 25, which, at its upper end, is shaped to provide stops 39, and pivotally secured to said standard 33, by means of a shaft 32, is a double acting rock member which is provided with fingers 34:--35, one for each lever. A lug 38, is provided at the outer end of said member which engages the stops 39, at the limits of movement of the member in each direction and actuating levers 52, are secured to said shaft 32, by

means of which the adjustment of the valve more clearly in my patent for Pneumatito adjust the valve closure to cut ofi com-,

munication between the inlet chamber and chamber 5). and to afford communication between exhaust chamber 4., and chamber 3, thereby exhausting the pressure from the cylinder. Rocking the shaft now in either direction of course admits pressure to the respective cylinder and actuatin the shaft from one limit of its movement to the other simultaneously permits one closure to admit inlet pressure to one working cylinder and the closure in the casing to exhaust the pressure from the other working cylinder.

Asshown, in Fig. 6, the mechanism for operating the stem 18, is somewhat modified and is adapted for individual operation. In this construction a lever 22, is pivoted at one end to a luq .21. and extends across the top of the head 18', of the stem 18. A cam lever .23. is pivoted to a standard 23', which, when actuated in one direction forces the stem 18. inwardly and on reverse actuation permits the spring to force the stem to normal. (oacting stops -6l, are provided which limits the movement of the am lever.

Numerous details of construction may be varied and we therefore do not desire to limit this application for patent otherwise than necessitated by the prior art.
