WATER-GATE.

SPECIFICATION forming part Of Letters Patent NO. 697,598, dated April 15, 1902. Application filed August 22,1901. Serial No. 72,956. (No model.)

To aZZ whom it nwy concern..-

Be it known that 1, CHARLES H. BAKER, a citizen of the United States, residing at Topia, Durango, Mexico, have invented an Improvement in Water-Gates; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in gates or devices for controlling the flow of water, steam, &c., in which a straightway valve is used. Its object is to provide a valve and valve-seats that may be removed when desired for grinding or repairs, and, further, to provide a gate in which fluid flowing in either direction may be controlled.

It consists, essentially, of a metal casing, oppositely disposed valve seats projecting within the valve-chamber, a two-part valve bearing against the seats, means by which the valve is kept in contact with these seats, and means by which said valve may be lifted.

It also consists in details more fully to be hereinafter described, having reference to the accompanying drawings, in which Figure 1 is a vertical section through the Fig. 2 is atop View of the lower portion of the valve-case, showing the valve in section on line 1 y of Fig. 1.

A represents the casing of the gate, into the chamber of which project the threaded sections 2, forming the valve-seats. This casing is preferably made of steel or cast-iron, while the sections or sleeves 2 are made of bronze. These sleeves have a short exterior projection 3, into which the ends of the pipe-sections 4 are screwed or otherwise suitably attached. The surface of this exterior part 3 is adapted to be engaged by a wrench, by which the sleeves may be inserted in or removed from the casing. Between the valve-seats 2 the valve 5 operates. This valve is made in two parts, each part adapted to bear against a respective seat and held in such position by means of spiral springs 6. So no matter from which direction in the conduit-pipes the pressure may come this valve will be competent to resist it. Each of the parts of the valve is provided with a central recess on its inner side. The valve is lifted by means of a stem or spindle 8, having the flanges 9, which set within the recess 7 and bear against the shoulders 10, forming the walls of the recess.

The stem is operated by suitable means, as a wheel 11.

Theinner walls of the casingAare so formed as to prevent the complete withdrawal of the valve from between its seats, and thus accidentally render the gate useless. The upper part of the chamber 12 is contracted, as shown, and a ledge 13 acts as a stop against the unnecessary opening of the valve. As shown,

the chamber 12 has inclined guides 13 on its inner wall to prevent the springs 6 from' spreading the two parts of the valve apart when the valve has been opened beyond a certain point. Without these guides when the'valve is open the springs would tend to spread the valve-sections and aiford opportunity for the flange 9 to disengage from the sockets 7. The casing is made in two parts bolted together at 14, so as to permit of access to the valve. Thus the valve or either of its parts and the sleeves are readily remov able at any time desired for purposes of refacing or grinding.

Gates of this character are of especial value where there is considerable sediment carried in the water and where consequent erosion of the parts is considerable.

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

The combination with a casing having oppositely-disposed openings, of pipe-sections within these openings, and having their inner ends forming valve-seats, a non-rotating valve-stem, a valve slidable between and in contact with said seats said valve made in two parts, and springs interposedbetween the two parts of the valve, for holding said parts in contact with the seats, said valve-casing extending above the valve to form a chamber having inclined guides upon its inner wall whereby the chamber is contracted in its upper part, to prevent the parts of the valve spreading apart when the valve is open, and a stop at the upper portion of the guides to prevent unnecessary opening of the valve.

In witness whereof I have hereunto set my hand.
