TH ROTTLE-VALVE.

SPECIFICATION forming part of Letters Patent No. 616,886, dated January 3, 1899. Application filed December 24, 189 7. Serial No. 663,326. (No modeLl T0 aZZ whom it may concern:

Be it known that I, HEINRICH BRINKMANN, a subject of the King of Bavaria, and a resident of Munich, Kingdom of Bavaria, Ger-. many, have invented certain new and useful Improvements in Throttle -Valves for Steam-' Pipes, of which the following is a full, clear, and exact description.

My invention relates to an improvement in controlling mechanism for throttlevalves.

The object of my invention is to provide a controlling mechanism by means of which the throttle-valve may be actuated from a distance,the operation being especially adapted for use on steam vessels, since by this arrangement it is possible to put the mechanism for controlling the throttle-valve at some point on deckas,for instance, near the wheel or the bridge-'so that when necessary the throttle-valve of the engine may be closed immediately from such points without the delay arising in transmitting orders to the engine-room.

' W'ith these objects in view and some others which will be obvious to those skilled in the art myinvention consists in the features, details of construction, and combination of parts which will first be described in connection with the accompanying drawings and then particularly pointed out in the claims.

In the drawings, Figure 1 is a detail sectional view of a part of an apparatus embodying my invention, being that portion which I will term the valve-operating mechanism. Fig. 2 is a sectional view of a complete apparatus embodying my invention and illustrating not only the valve-operating mechanism, but also the valve-actuating mechanism. Fig. 3 is a detail sectional view taken on the line A B, Fig. 1.

Referring to the drawings, X is a steamsupply pipe, in which is located a throttlevalve 6 in such a manner that the steam in the supply-pipe X will tend to open the valve, the live steam passing in the direction of the arrows shown in Fig. 2. On the upper portion of the throttle-valve body is secured the framework of the valve-operating mechanism, said framework being provided with a downward-extending plug it, which enters an opening in the top of the valve-body and serves as a stop device to limit the upward movement of the throttle-valve e, the latter having a stem 6 which projects through the said framework and is provided with a crossarm f, pivoted to its upper end, the stem being suitably packed when it passes through the framework, as by a gland e screwed into an opening in the framework and bearing against packing a".

At each side of the valve-stem e are arranged two cylinders, formed in the framework, within which are pistons it, having piston-rods 10 k respectively connected by links f to the ends of the cross-arm f. The cylinders are provided at each end with ports for a purpose hereinafter described.

The valve-actuatin g mechanism consists of a slide-valve chest, in which is located a slidevalve or, movable over a double set of ports m or, arranged two on each side of an exhaust-port m The interior of the valvechest is supplied with steam through an inlet m in the direction of its length by any suitable means, as by a valve-rod n,passing outward through the valve-chest and connected by a link 0 to one end of a bell-crank lever j, pivoted at a fixed point j.

The two inner ports m m of the slide-valve are connected to the ports at the lower ends of the cylinders of the valve-operating mechanism by means of pipes c and d. The outer ports of the slide-valve are connected to the upper ports of the said cylinders by pipes at and b. In the latter pipes at their connection with the ports of the cylinders are placed check-valves o, arranged to be opened by live steam flowing through the pipes or b to the cylinders and to be closed by the exhauststeam from said cylinders, each check-valve having small openings 12, through which the exhaust-steam may escape gradually.

The operation of my device is as follows: \Vhen' the slide-valve is moved to one end by means of the lever j, it will cover the exhaustport m and the ports m and m connecting the latter with said exhaust-port, the ports The slide-valve is arranged to be moved m at being then uncovered and receiving live steam, which passes through pipes 12 and c, the former supplying steam to the top of piston 70, while the latter supplies steam to their respective cylinders, the piston 7t" will be retained in that position, while the piston 7; will be forced upward, thereby lifting the valve e, being assisted in this by the pressure of the steam in the main steam-pipe a; forcing the said valve upward. \Vhen the slidevalve is moved to the opposite end of the valve-chest, the ports m and m are connected with the exhaust-port m and the ports m and m receive live steam, which passes through the pipes (Z and a to the under side of piston is and the top of piston 70, respectively, pushing the latter to the bottom of its cylinder and forcing the piston 76 to the upper end of its cylinder, thus also causing the throttle-valve e to be opened, as before. It is immaterial, therefore, as to which extreme position the slide -valve occupies, since in either of its extreme positions the throttlevalve 6 will be opened and the steam-supply passing through the pipe w is not interfered with. If now it be necessary to close the throttle-valve from the remote point at which the valve-actuating mechanism is located, it is only necessary to move the lever j, so as to bring the slide-valve m into its intermediate position, as shown in Fig. 2, whereupon the live steam enters the upper ports of the cylinders through pipes to and b, forcing open the check-valves v and pressing both pistons 7.; and down ward, thereby closing the throttle-valve e, the exhaust-steam from the cylinders escapingfreely through the pipes c and (Z, ports m and m and exhaust-port 171 The checkvalves 6 are provided in the pipes a and b in order to cushion the pistons a and 7s, and thereby avoid shocks on opening the throttle-valve e, the respective checkvalve 1) closing when the slide-valve is thrown to either of its extreme positions owing to the pressure of the exhaust-steam, and thereby preventing the too rapid escape of the latter, which is compelled to pass outward through the small holes or openings t in the respective check-valve.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination with a main pipe, a throttle-valve therein and provided with a stem, a pair of cylinders, one at each side of said stem, each cylinder provided with a port at each end, and a piston in each cylinder, of a piston-rod connected to each piston, means for transmitting motion from the piston-rods to the throttle-valve stem, a slide-valve chest having inner and outer ports and an exhaustport, connections between the outer ports of the slide-valve chest and the ports at one end of the cylinders, connections between the inner ports of the slide-valve chest and the ports at the other end of the cylinders, a slide-valve movable over the ports of the slide-valve chest, and means for moving said slide-valve.

2. The combination with a main pipe, a throttle-valve therein and provided with a stem, a pair of cylinders, one at each side of said stem, each cylinder provided with a port at each end, a piston in each cylinder, and a piston rod connected to each piston, of a cross-arm pivoted to the valve-stem, a link connecting each piston to the cross-arm, a slide-valve chesthaving inner ports, outer ports and an exhaust-port, connections between the outer ports of the slide-valve chest and the respective ports at one end of the cylinders, connections between the inner ports of the slide-valve chest and the respective ports at the other end of the cylinders, a slide-valve movable over the ports of the slide-valve chest, and means for moving said slide-valve.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

HEINRICH BRINKMANN.
