VALVE FOR BADIATORS.
Specification of Letters Patent.
Patented Oct. 2, 1917.
Application flled March 16, 1917. Serial No. 155,214.
' To all whom it may concern:
Be it known that l, EARL I). PEERSTONE, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Valves for Radiators, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
' This improvement is designed for the purpose of providing a quicker and more convenient means for controlling the supply of steam to the radiator. It is designed to be operated by a persons foot, both to open and close, and is so constructed that the valve will always be either fully open or closed, thereby preventing what is known as a, cracked valve, which is a term applied to a valve that is slightly open, permitting steam to enter but preventing the return of the water, which accumulates in the radiator and may cause either water-hammer or flooding.
The valve consists of a casing, 1, having an opening, 1, for the admission of steam from the supply pipe, and an opening, 1*, for the passage of steam to the radiator. A bonnet, 2, closesthe top of the casing and has a recessed space, 2, for receiving the packing,
3, which is secured in place by a packing nut, 4. A stool, 5, which seats on a shelf, 2", formed on the bonnet, 2, serves to support a catch, 6, by means of lugs, 7, a spring, 8, serving to maintain the catch in operative position, the catch being designed to engage a shoulder, .9, formed on the valve stem, 9, when the valve is in closed position, as shown in ,Fig. 1.- A collar, 10, attached to the bonnet, 2, serves to secure the stool, 5, which is adjustable in position so that the tread, 6, formed on the outer end of the catch, 6, may be set in a convenient position to operate. A cap, 11, attached to the upper end of the valve stem, 9, serves as a tread to close the valve. A valve disk, 12-, is loosely hung on the lower end of the valve stem, 9, by means of a collar, 13, so as to provlde a certain amount of lost motion.
A collar, 14, attached to the valve stem, 9, serves to engage the upper end of two springs, 15, and 16. The'lower end of the spring 15 seats on the. bottom of the casing, and this spring is employed to raise the valve stem and the valve disk to open position, as shown in Fig. 2, when the catch, 6,
stem is pushed inward by the pressure of a persons foot it must travel far enough to allow the catch, 6, to engage its seat, 9. When the stem reaches its extreme inward position in the closing of the valve the shoulder, 9 is spaced inwardly of the catch, 6, thus making possible a slight back kick of the stem. When the pressure is relieved the stem has a slight upward or outward movement, until the catch becomes effective, and it is this slight back kick that necessitates a yielding resistance means to seat the valve disk before the shoulder on the valve stem in its inward movement clears the catch, and to keep the valve disk seated after the stem ln'cks back. It is of course, necessary to have this spring of suflicient tension to resist the pressure of steam against the lower face of the disk.
Having thus described my invention, I claim 1. A valve device comprising a casing, a valve disk, a valve stem for operating the valve disk, having an inward movement after the valve disk is seated to permit a catch to engage the valve stem and having a subsequent slight outward movement after the catch has passed into engaging position,
and a catch for securing the valve stem to prevent further outward movement of the same.
2. A valve device comprising a casing, a valve disk, a valve stem for operating the valve disk, having an inward movement after the valve disk is seated to permit a catch to engage the valve stem and having a subsequent slight outward movement after the catch has passed into engaging position, a catch for securing the valve stem to prevent further outward movement of the same, and yielding resistance means for opposing the inward movement of the valve stem.
3. A valve device comprising a casing, a valve disk, a valve stem for operating the valve disk, having an inward movement after the valve disk is seated to permit a catch to engage the valve stem and having a subsequent slight outwart movement afterthe catch has passed into engaging position, a catch for securing the valve stem to prevent further outward movement of the same, and a tread for releasing the catch. D 0 4. A valve devlce comprising a casing, a
5 valve disk, a valve stem for operating the valve disk, having an inward movement after the valve disk is seated to permit a catch to engage the valve stem and having a subsequent slight outward movement after 10 the catch has passed lnto engaging position,
yielding resistance means interposed between the valve stem and the valve disk to hold EA'RL D. PEERSTONE.
