UNITED STATES PATENT OFFICE.
JOSEPH HIGGINBOTHAM, OF PHILADELPHIA, PENNSYLVANIA.
STOP-VALVE.
Specification of Letters Patent No. 27,801, dated April 10, 1860.
To all whom it may concern:
Be it known that I, Jos. HIGGINBOTHAM, J r., of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Stop- Valves; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.
My invention consists of a slotted guide, a cap and slotted valve spindle in combination with a second spindle and cam, part of the said guide forming, in conjunction with the cap, a stufling box for the valve spindle, and the several parts being arranged in respect to each other and to the body of the stop valve, substantially as described hereafter so as to perform the three fold duty of operating and guiding the valve spindle and maintaining it tightly packed.
In order to enable others skilled in the art, to make and use my invention, I will now proceed to describe its construction and operation.
On reference to the accompanying drawing which forms part of this specification, Figure 1, is a vertical section of an ordinary stop valve, with my improvements. Fig. 2, an end view of Flg. 1; Fig. 3, a sectional plan on the line 1, 2, Fig. 1; Fig. 4, a detached sectional view of part of the valve.
Similar letters refer to similar parts throughout the several views.
A is the body or casing of an ordinary stop valve having the usual branches a and a to which are attached the pipes for the passage of steam water or gas. The interior of the casing is, as usual in this class of stop valves, separated into two chambers by a partition 6 having an orifice 0 the edge of which forms the seat for the valve f, the latter being attached to the lower end of the spindle B. This spindle passes through the cap 0, which is screwed to the top of the casing A, and which has a projection 02 screwing into the lower end 6 of the guide D. Between the end of the projection (Z of the cap and the bottom of the recess in the lower end 6 of the guide, is sufficient room to admit a suitable amount of packing h.
The upper and enlarged end of the spindle B has an oblong slot into which the cam G fits snugly but so as to move freely to a limited extent. The guide D has also an oblong slot m near its upper end in order that the cam may be inserted into and withdrawn from its place within the slot of the spindle. This cam G is attached to the square portion of the spindle H, which is furnished with a suitable handle a and which turns in the guide D at the opposite sides of the slot m. In the spindle B are two openings surficiently elongated to allow the valve spindle to rise and fall freely without interfering with the spindle H, so that at the'point where these openings cross the slot for the cam, the spindle consists of four pillars i, i, seen in Fig. 3.
By turning the handle a, and with it the cam G, the latter may be brought to bear on the bottom of the slot of the valve spindle,
thereby depressing the latter and closing the valve to its seat, or the handle and cam may be so turned that the latter will act on the top of the oblong slot, in which case the spindle D with its valve will be raised.
It will be observed that the valve spindle is guided both above and below the point where the power is applied by the cam to raise and lower it, it will also be seen that the power is applied directly over the center of the spindle. By this arrangement all lateral strain both on the guide D and spindle B is avoided.
I am aware that a cam has been heretofore used for operating the valves of stop cocks. I therefore do not claim broadly the use of the cam G for operating the valve, but I limit my claim to and desire to procure Letters Patent for The guide D with its slot m, the cap 0, and spindle B, with its two slots crossing each other, in combination with the spindle H and its cam G, when a part of the said guide forms in conjunction with the cap 0, a stuffing box for the spindle B and when the several parts are arranged in respect to each other and to the body of the valve substantially as specified.
In testimony whereof, I have signed my name to this specification before two subscribing witnesses.
JOSEPH HIGGINBOTHAM.
Witnesses HENRY HowsoN, CHARLES Howson.
