JAMES WALSH, 0F PHILADELPHIA, PENNSYLVANIA.
- IMPROVEMENT IN STOP-VALVES.
Specification forming part of Letters Patent No. 115,794, dated June 6, 1871.
Nature and Object of the Irwent'ion.
My invention consists of a stop-valve, fully described hereafter, constructed with a view of rendering the joints in the said valve steam and water tight without the aid of any elastic packing, the valve being especially applicable to hot-water or steamheating pipes.
Description, of the Accompanying Drawing. Figure l is a sectional view of my improved a sectional view on the line 1 2, Fig. 1.; and Fig. 3, a detached view;
General Description.
A represents the valve-casin g, n ear the lower end of which are the inlet and outlet branches, arranged in line with each other, and threaded, as usual, for attachment to the supply-pipe O and dischargepipe D. The supply-pipe G communicates with the interior of the casing A through an opening, a, directly beneath the valveE, the latter consisting of the semi-spherical portion i), adapted to a similarly-shaped seat, N, in the bottom of the case A, and a cylindrical portion, Z2 arranged to fit and move freely in the interior of the said case. The valve E is operated by a screw, F, adapted to internal threads in the said valve; but the latter is prevented from turning in the casing A by wings, cl [1, which project from it into the vertical slots d d of a hollow plug, G, Fig. 3, which is screwed into the upper portion of the case A. On top of the screw-plug G is formed a groundseat, c, to which is adapted the edge of a disk, 6. The upper edge of the casing A is also accurately turned and ground to form a seat for a disk, f, both of these disks turning with, and, if desired, forming part of the screw-spindle F. Between the upper disk f and the under side of the screwcap H, and surrounding the spindle F, is an annular spring, S, the object of which is to hold the disks f and e firmly'in their seats with a slightly elastic pressure, which must be sufficient to resist that of the steam or water in the pipes. In some cases I dispense with the spring and maintain the disks in their seats by the cap H but I prefer the use of the spring in the manner described.
It will be seen that by the above-described arrangement I secure perfectly steam and water tight joints without the aid of elastic packing, common to, but always objectionable in, stop-valves used for steam or hot-water pipes, as such packing interferes with the free working of the valves and is difficult to keep in proper order. It will be seen that with a slight modification of the inlet and discharge branches the valve can be converted into a faucet or cook suitable for wash-basins, bath-tubs, 850., the interior arrangement of the ground joints being maintained.
Claims.
1. The combination with the screw-spindle F, carrying avalve, E, of the supplementary valves or disks f and 6, adapted to seats on the valve-casing and on a screw-plug, G, fitted within the said casing, all substantially. as specified.
2. Thescrew-plugGfitted within the casing, slotted for the reception of the Wings at of the valve E, and having a seat formed on it for the disk or valve 6, all as set forth.
Intestimony whereof I have signed my name to this specification in the presence of two subsoribin g witnesses.
JAMES WALSH.
