VALVE.

SPECIFICATION forming part of Letters Patent No. 684,913, datedOctober 22, 1901.

Application filed February 25. 1901- Serial No. 48,705. (No model.)

T0 all whom, t may concern:

Be it known that I, JAMES M. CORDELL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Valves 5 and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use 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 improvements in valves, and comprises a valve which is especially adapted for use in connection with reineries in apparatus for treating sh and other matter in large quantities for the purpose of extracting oil therefrom and separating'the solid matter for the purposes of fertilizer. Tanks are used in which the fish or other `matter is first introduced, and the oil or liquid is extracted therefrom, after which the solid matter and portions of the liquid are deposited in a steam-drier, in which said matter is dried and subsequently is produced in the form of a powder or meal which is suitable for fertilizer. The connection between the tanks from which the oil is extracted and the drying-receptacle consists of'a series 'of pipes in which valves are placed, through which more or less solid matter mixed with liquid passes. Heretofore considerable trouble has been experienced in providing a valve that would not clog up, and thereby become inoperative in a short space of time.

The object of the present invention is to construct a valve which will meet all requirements in apparatus of this character. It has not been deemed necessary to illustrate the apparatus in the drawings, as it comprises no part of the present invention and is of wellknown construction.

In a detail description of my invention reference is made to the accompanying drawings, of which-- Figure 1 is a vertical side elevation of my improved valve. Fig. 2 is a vertical sectional elevation of the same. Fig. 3 is a transverse section on the line oc a; of Fig. 1.

The valve-casing consists of a globe-body :A and flanges A', by which the said valvecasing is seeured between the ends of piping. (Not shown.) The interior of said casing is provided with an annular valve-seat B and an annular chamber C, with a plurality of ports D extending from said chamber tothe valve-seat.

E designates a cone-shaped valve pointing upwardly and having transverse bridges F and FC This valveseats upwardly against the valve-seat B. The valve-stem G passes through the bridges F and F and is secured thereto in any suitable manner to operate the valve in both directions. The lower portion of said valve-stem is provided with a screw Gr and a spline H, into which a key H' on the housing J projects to prevent the valve from being given any rotary movement through the operations of the worm-gearing, hereinafter described. The tapering surface of the valve is an essential feature in the construction thereof, as thereby the matter deposited on the sides of the valve is prevented from finding a permanent lodgment thereon, as would be the caseif any portion of the valvesurface was flat. The matter coming in contact with the slanting surface of the valve readily passes down through the opening between the valve and the seat.

I is a worm-wheel placed in a horizontal p'osition within thehousing J. The screw G passes through the axis of the worm-wheel I, which is also screw-threaded to engage the same.

`K is a shaft lying at right angles to said worm-wheel I and having bearings K on opposite sides of the housing J. The housing J is secured to interior lugs L on opposite sides of the casing by means of screws M, which pass through opposite sides of the housing and penetrate said lugs. The shaft K has a. worm N, which engages with the wormwheel I, and thereby the said worm-wheel may be moved in either direction to raise or lower the valve. The shaft K, upon which the worm N is located, passes out through the front portion of the casing and is provided with a hand-wheel O, by means of which the said shaft is operated. connection is made with the chamber O- for the introduction of steam or water for thelv purpose of keeping the valve-seat B and the valve-surface adjacent thereto free from any Suitable pipe accumulations of matter' that would otherwise prevent a proper seating of Jthe valve or a proper opening between the valve and said seat.

The object and purpose of the housing J is to protect the gearing from accumulations of any solid matter-such, for example7 as lishbones, sh-heads, dac. Access may be had to remove such matter from the upper side of the housing whenever necessary by means of a hand-hole, which is closed by a cover P, the same being located on the side of the valve on which the hand-wheel is placed.

Having described my invention, I claim- 1. In a valve of the character described, the combination of a valve-casing having an annular seat therein, an annularl chamber surrounding said seat, a series of ports forming a communication between said chamber and valve, a cone-shaped valve in said casing, a stem connected to said valve, a portion o f said stem being screwthreaded, a housing Within the valvecasing below the valve through which the said screw-threaded portion of the stem projects, a worm-wheel inclosed within said housing and having a screw-threaded engagement with the screw portion of the stem and by means of which the said stem is actuated to open or close the valve, a wormshaft projecting through said housing and engaging the worm-wheel, and

an exterior hand-wheel by means of which the said w0r1n-shaft is actuated to transmit the necessary movements to the valve.

2. In a valve for the purposes speciiied, the combination of a valve-casing having an annular valve-seat therein, an annular chamber surrounding said valve-seat, a plurality of ports forming communications between the valve-seat and said chamber, a cone-shaped valve within said casing, a valve-stem connected to said Valve, a portion of said valvestem being provided with screw-threads, a housing within said valve-casing, supports projecting from opposite sides of the valve casing to which said housing is secured, means for preventing the valve-stem from rotating under the movement imparted thereto, a worm-wheel inclosed within the housing and engaging with the screw-threaded portion of the valve-stem, a Worm-shaft j ournaled in the casing and engaging with the Worm-wheel, and a hand-wheel by means of which the said Worm-shaft is rotated to impart movement to the valve-siem, to open or close the valve.

In testimony whereof I affix my signature in presence of two Witnesses.

JAMES M. CORDELL.
