JOHN S. LENG, OF WEST NEW BRIGHTON, NEW YORK.
VALVE.
SPECIFICATION forming part of Letters Patent No. 298,865, dated May 20, 1884.
Applieaiion filed May 22, 1883. (No model.)
To ctZZ whom, t may concern/ Be it known that I, JOHN S. LENG, of Vest New Brighton, in the county of Richmond and State of New York, have invented a certain new and useful Improvement in Valves, of which the following is a specification.
My invention relates to what are commonly as straight-way or gate 7 valves, in which the valve is opened and closed by a sliding movement in a direction transverse to the water way7 or passage through the shell or casing, andin which the valveisin many cases attached to a carriage having a sliding movement in guides formed in the valve shell or casing.
The invention consists in the combination, with a valve, its shell or casing, and means for moving the valve in a direction transverse to the watfr way or passage, the said valve being preferably attached to a carriage movable in said direction, of an adjustable and removable seat screwed into one of the pipe sockets or openings of the shell or casing to a position inward of the outer end of said socket or opening, so as to leave on the outer side of the said seat a screw-threaded portion of the socket or openings for the reception of a pipe. The valve-seat is faced off truly before being inserted in the shell or casing, and is then inserted into the pipe socket or opening and screwed in until it comes to an even bearing on the valve,which previously has been moved into a closed position. In valves of the kind above referred to, the carriage to which the valve is attached is often operated by an arm or cam-like lever mounted on a rock-shaft which projects from the valve shell or casing through a stuffing-box; and my invention also consists in a novel construction of this stuffing-box, as particularly hereinafter described.
The invention also consists in a novel and simple means of connecting the valve with its carriage, as hereinafter described.
In the accompanying drawings,Figure 1 is a sectional view of avalve embodying my invention. Fig. 2 is a section thereof in a plane transverse to the water way or passage through the valve. Fig. 3 is a plan, the bonnet of the shell or casing being removed and the valve in an open position. Fig. iisadetail sectional view showing a portion of the rock-shaft and stuffing-box, and Fig. 5 is a detail sectional view of the valve and carriage.
Similar letters of reference designate corresponding parts in all the figures.
A designates the shell or casing of the valve, which is of ordinary form, and is provided with the usual pipe sockets or openings, A.
B designates the adjustable and removable valve-seat. lt consists simply of a ring, the inner face, c, of which is fiat and forms the valve-seat proper. This ring is externally screw-threaded correspondingly to the pipe socket or opening A', and is capable of being screwed into said pipesoeket from the outer end thereof to a position considerablyinward of the outer end of the socket, so as to leave a screw-threaded portion of the socket on the outer side of the seat for the reception of a pipe. The pipe-socket is of course slightly taper, and the seat is adapted to be screwed up tightly therein. The ring B, which forms the seat,is provided with two or more internal lugs or projections, b, with which a wrench may be engaged to turn it in.
O designates the valve proper, which is attached to and moved in a direction transverse to the water way or passage by a carriage, D, which is capable of sliding freely in guides c, formed in opposite sides of the shell or casing A. These guides are inclined relatively to the valve-seat B, so that the valve will be crowded against the seat as the carriage is moveddownward orinward. The guides c are open at the upper ends, and the casing or shell is provided with the ordinary screwed cap or bonnet A2. Then this cap or bonnet is removed, the carriage may be inserted directly into the guides.
The valve C is connected with the carriage D in a novel manner, as seen most clearly in Fig. 5. The back of the valve is rounded or convex, and at the center thereof there is a projection, d, which enters a hole, e, in the carriage D, and is secured therein by a washer, f, and a screw, g, which is inserted into the said projection. The projection al is some what smaller in diameter than the hole e, which it enters, and the carriage is beveled on each side around the hole e, so that it can adjust itself with perfect freedom in any direction independently ofthe carriage, although it movesr IOO with the carriage in a direction transverse to the water way or passage. As seen in Fig. 5, the washerf is of 4such small diameter that-it will enter the beveled opening on the back of the carriage around the hole e.
In inserting the seat B the valve is moved down into its closed position, and the seat, the
- face a of which has been previously surfaced off truly, is screwed in until it comes to a solid bearing on the face ofthe valve. In the present example of my invention the carriage D is moved to open and close the valve C by means of a rock-shaft, E, which projects outside the shell or casing A, and a cam-like lever or arm F, fitted upon the shaft within the shell or casing. The rock-shaft E may be turned by means of a lever or arm, E', secured to it, and within the shell or casing it has a square or angular portion7 7L, to which the cam-lke lever or arm is iitted. The carriage D is provided on the back with pairs of arms fi i', between which said pairs the lever F works, and the lever has horns j, projecting in opposite directions and between the two arms of each pair. When the rock-shaft E is turned in one direction, the horns j, acting on the arms i, raise the carriage and open the valve, andy when turned in the other direction said horns engage with the arms fr" and move ,the carriage to close the valve. In moving the carriage to close the valve the portion or projection lo on the lever bears on top of the carriage, as shown in Fig. 1, between the arms @'13, and thus presses the carriage down and wedges the valve up against its seat.
Upon the side ofthe shell or casing A is a recessed projection or hub, A3, like an ordinary stuffing-box, and which receives a collar, E2, on the rock-shaft.
G designates an externally screw-threaded plug or gland, which screws into the projection A3, like the gland of a stuffing-box.
In the outer face of the collar. Ez is formed an annular groove, Z, and the plug or gland G is formed with a valve-like projection or face, m, which, as the nut is screwed up, enters and snugly lits in the groove Z. The groove forms a seat, and the plug or gland, or the projection thereon, forms a valve, which prevents leakage around the rock-shaft and between it and the plug or gland. The collar E2 iits and is held between the rigid surfaces formed by the bottom of the stuffing-box and the end of the plug or gland.
If desired, the projection m might be on the collar E2 and the groove Zin the end ofthe nut.
Vhat I claim as my invention, and desire to secure by Letters Patent, is-v `1. The combination, with a valve, its shell or casing, and means for moving the valve in a direction transverse to the water lway or passage, of an adjustable and removable seat screwed into one of the pipe sockets -or openings of the shell or casing to a position in- Iward of the outer end of the socket or opening, so as to leave on the outer side of 'said seat a screw-threaded portion of the socket or opening, for the reception of a pipe, substantially as herein described.
2. The combination of a valve shell or casing, a carriage sliding therein in a direction transverse to the water way or passage, a valve attached to the carriage, but capable of adjusting itself` in all directions independently of the carriage, and an adjustable and removable valve-seat screwed into one of the pipe sockets or openings in the shell or casing to a position inward of the outer end of said socket or opening, so as to leave on the outer side of said seat a screw threaded portion of the socket or opening,for the reception of a pipe, substantially as herein described.
3. The combination, with the stuffing-box, of the valve-operating rock-shaft provided with a collar tting in said boX, and the outer side of which forms a valve-seat, and an eX- ternally screw-threaded plug or gland screwed into the box, and having a valve-like face which bears upon and forms a tight joint with said collar to prevent leakage between the shaft and the plug or gland, the said collar being held between the rigid surfaces formed by the bottom ofthe stuffing-box and the inner end of said plug or gland, substantially as herein described.
4. The combination ofthe stuffing-box A3,the shaft E, provided with acollar,E2, in the outer side of which is a grooved seat, l, and the eX- ternallyscrcw-threaded plug or gland G, hav- IOO ing a valve-like projection, m, which enters and forms a tight'joint with said groove, the said collar being held by the rigid surfaces formed by the bottom of the stufngbox and the inner end of said plug or gland, substantially as herein described.
5. The combination'of the valve C, having a rounded back and a projection, d, the carriage D, having the hole c beveled in the back, and the washer f and screw g, substantially as herein described.
6. The combination of the valve C, carriage D, provided with the arms z', the lever F, fitting between said arms, and provided with horns j, projecting from opposite sides, and engaging with the arms t' z', and also provided with the portion 7c, bearing on the top of the carriage at a point between the arms and the rock-shaft E, substantially as herein described.
