tlN TE STATES LOUIS GASZ, OF NEW YORK, N. Y.

VALVE.

SPECIFICATION forming part of Letters Patent No. 635,537, dated October 24, 1899.

Application filed May 1'7, 1899. Serial No. 717,196. (N0 model.)

To all whom, it may concern:

Be it known that I, LOUIS GASZ, of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Valve, of which the following is a full, clear, and exact description.

This invention relates to improvements in valves, particularly for governing steam to the steam-cylinder of a direct-acting steampump; and the object is to provide an auxiliary piston and a system of ports so arranged that the steam-supply to the cylinder will be completely balanced and regular.

I will describe a valve embodying my in-.

vention and then point out the novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional plan view of a valve mechanism embodying myinvention. Fig. 2 is a vertical section of the same. Fig. 3 is a partial elevation and partial section on the line 3 3 of Fig. 1. Fig. 4c is a section similar to the section shown in Fig. 1, but showing the parts in different positions. Fig. 5 is a section on the line 5 5 of Fig. 2, and Fig. 6 is a section on the line 6 6 of Fig. 2.

Referring to the drawings, 1 designates a steam-cylinder in which the piston 2 operates, and this cylinder has inlet-ports 3 4 and an exhaust-port 5. Arranged on the cylinder 1 is an auxiliary cylinder 6, in which is an auxiliary piston, which comprises two heads 7 8, connected bya stem 9. Movable with the piston 7 8 is a main valve 10, having a chamber 12 and a transverse port 13. This main valve has an upwardly-opening longitudinal slot 14 formed in it, in which the stem 9 engages, and the said main valve is prevented from rotary movement by means of a pin 15, extended from the wall of the cylinder into said slot 14. At one end of the cylinder 6 is an auxiliaryvalve cylinder 16, in which an auxiliary-pis ton valve 17 is arranged. This piston-valve 17 has a piston-rod 18 extended through the head of the cylinder 16, and adjust-ably mounted on this piston-rod 18 are collars19 20, adapted to be engaged by a tappet-arin 21, which has an opening through which the rod 18 freely passes, and this arm 21 is extended from the rod 22 of the piston 2.

At one side the auxiliary-piston valve 17 is provided with a recess 23, and at its opposite side it is provided with a recess 24. recesses extend circumferentially of the piston-valve and are designed to place certain ports in communication, as willbe hereinafter described. Communication is provided between the cylinder 16 and the cylinder 6 forward of the piston-head 7 through a port 25, and communication is provided between said cylinder 16 and the cylinder 6 forward of the piston-head 8 by a port 26. On one side of the piston-valve 17 an exhaust-port 27 leads from the cylinder 16 to the cylinder 6, and from the opposite side of said piston-valve 17 an exhaust-port 28 leads from the cylinder 16 to the cylinder 6.

A steam-inlet port leads through the walls of the cylinders at one side and provides communication between the cylinder 6 and the cylinder 16, and its end terminating in the cylinder is in line with the end of the port 26 in said cylinder so that the two ports may be put into communication by the recess 24. At the opposite side a port 30 leads from the cylinder 6 into the cylinder 16 and is designed to be put in communication with the port 25 through the recess 23.

The piston-valve 17 has a port 31, which extends through the forward end of said piston-valve and out at one side, and a port 32 extends through the opposite end of said piston-valve and out through the opposite side.

The cylinder 6 has a steam-inlet 33, and while the parts are in the position indicated in Figs. 1 and 2 steam is passing through the port 3 to the front side of the piston 2 and an is passing through the port 1 into the exhaust-port 5 and through the main valve 10. Steam forward of the piston-head 7 will remain until the tappet-arm 21 engages with the collar 20 and moves the auxiliary-piston in the piston-valve 17 with the port 25, and the steam exhausts through the port 28 into the exhaust-port 5, and at the same time steam is admitted through the port 29 into the recess 24 in the auxiliary-piston valve 17 into the port 26 to the front side of the pisvalve 17 forward, which connects the port 31 These exhaust from the opposite side of said piston ton-head S, forcing the valve into the opposite position, as shown in Fig. 4. During this movement of the piston-valve 17 the steam rearward of said piston will exhaust through the port 27 and to the port 5. It will be noted that the outlet end of the port 27 is closed by the main valve 10 during a short movement of the valve 17. When the'valve 17 is in this opposite position, steam will be admitted through the port 29, the recess 24, and the port 26 to the front side of the valve-head 8. The steam thus admitted will force the main valve to its'opposite position and put the port 4 in communication with the live-steam entrance. During this movement of the valve the steam forward of the head 7 will pass through the port 25 and the port 31 to the front side of the piston-valve 17, and it will exhaust through the port 28.

It will be seen in this invention that the auxiliary piston 7 governs the admission of steam to the steam-cylinder 1 and the piston operating in said steam-cylinder governs the movements of the valve 17. The valve 17 is prevented from rotary movement by means of an arm 34, having a horizontally-extended portion which passes through an opening in a fixed arm 35.

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent- The combination With a steam-cylinder and a piston therein, of an auxiliary cylinder mounted on the steam-cylinder, an auxiliary piston in the auxiliary cylinder, a main valve operated by the auxiliary piston for governing ports between the auxiliary cylinder and steam-cylinder, an auxiliary-valve cylinder on one end of the first-named auxiliary cylinder, an auxiliary valve in the valve-cylinder, the said auxiliary Valve having recesses in its opposite sides, each recess being adapted to put two ports leading from the valveeylinder into the auxiliary-piston cylinder in communication, the said auxiliary valve also having ports through its opposite ends and sides for connecting respectively with ports leading from the auxiliary-valve cylinder to the opposite ends of the auxiliary piston, means operated by the piston in the steamcylinder for shifting the auxiliary valve, and means for preventing a rotary movement of the auxiliary valve.
