Description

BUTTERFLY-VALVE.
Specification forming part of Letters Patent NIO. 23,902, dated May 10, 1859; Reissued July 2, 1861,
To all whom it may concern:
Be it known that we, NATHAN Corn and `W1LL1AM HoDGsoN, both of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Butterfly-Valves; and we do hereby declare that thefollowing is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this speciication, in which- Figure l, is a top view of a valve and its box, complete, constructed according to our invention, in form to be applied as a steamengine regulator in connection with a governor. Fig. 2, is a front view of the same. Fig. 3, is a central section of the same in a plane perpendicular to the axis of the valve. Fig. 4, is a section taken in a plane corresponding with Fig. 3, of a section of the valve. l
Similar letters of reference indicate corresponding parts in the several figures.
Our invention consists in certain means of controlling the movement of the valve to prevent it opening the wrong way and opening farther than is desired, which also provide for its opening in either direction, as
may be desired.
To enable others to make and use our invention we will proceed to describe its construction and operation.
A, is the valve, B, B1, the box, and C, the valve spindle. The valve may be made of the usual form and of about the usual thickness, with the exception that instead of having its periphery or face beveled, it has it turned to present the portion of a sphere concentric to the spindle C, or axis of motion, as shown in Figs. l, 3 and 4. rIhe transverse section of the valve may be as shown in Fig. 3, which approximates to the common form, or as shown in Fig. 4, so as to give more material in the vicinity of the spindle, C. It is or may be fit-ted to the spindle in the usual manner.
The box B, B1, has the seat c, c, turned of a similar spherical form to the face of the valve to make a close but easy fit thereto. The fitting should be completed by grinding. To provide for the insertion of the valve in the seat, the box must be divided through the center of the spherical surfaces of the seat, in two parts B, B1. The division may be in a plane passing right through the axis of the spindle or perpendicular thereto. The latter method of division is shown in the drawing, as it has some practical advantages. The two parts B, B1, of the box are provided with lugs a, a, on each side to receive bolts I), o1, by which they are bolted together. The seat c, c, needs to be no wider than the face of the valve and may be of precisely the same form, that is to say, with an enlargement near the valve spindle to correspond with the enlargement of the valve at those points. By providing in the box a cavity, on each side of the seat, as shown at CZ, d, Figs. 1 and 3, the valve, when open, has its openings increased or diminished in a greater degree by a given movement than an ordinary throttle valve, as the edges of the valve move directly away from the seat, instead of parallel with it.
The spindle C, is. shown as fitted into a stuffing-box D, in the part B, of the box, but a stufling box will be unnecessary if the spherical faces of the valve and seat be properly fitted, as in that case no steam could escape around the spindle.
E, is a slotted plate attached securely by the bolt b1, to the lvalve box. The slot e, in this plate is in the form of an arc concentric to the valve spindle. F, F1, are two stops made adjustable in the said slot, and capable of being secured in any position therein, by nuts f, applied to screw threads cut upon them. These stops are for the purpose of limiting the movement of the valve lever G, which plays between them, one of them stopping the valve when closed, and preventing it giving steam the wrong way, and the other stopping it when it has the greatest desired amount of opening. The stops are. shown in Fig. 2, adjusted to permit the opening of the valve in the direction of the arrows shown in Fig. 3, butby shifting the lever G, on the spindle, either with or without changing the position of the said stops, the movement of thevalve may be controlled in a similar manner in opening in the reverse direction, and hence the valve is applicable in connection with any arrangement of a governor.
The spherical-faced butterfly valve may be used not only as a governor valve, but as a cut-off for steam engines, or for any purpose in which a close-fitting, perfectly balanced valve is required.
That we claim as our invention and de- NATHAN COPE.
