VALVE.
SPECTFIGATION forming part of Letters Patent N o. 725,640, dated April 14, 1903. Application tiled January 4, 1902. Serial No'. 88,401. (No modela) To all whom, it may concern:
Be itknown that I, WILLIAM N. WEMMER, a citizen of the United States, and a resident of Trenton, in the county of Mercer and State of New Jersey, have made a certain new and usefulInvention in Automatic Valves forHot- Water Radiators; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
Figure l is a side elevation ot my valve as applied. Fig. 2 is a similar View showing modified form of valve. Fig. 8 is a side elevation of a modified form of the invention having a valve for cutting ott the water. Fig. 4 is a similar view of the valve shown in Fig. 1. Fig. 5 is a detail end'view ot the valve. Fig. 6 is a detail fragmentary sectional View illustrating thevalve-block and valve'as raised to close the opening h.
The invention relates to automatic airvalves designed mainly for use in connection withhot-waterheating apparatus; andit consists in the novel construction and combinations of parts, as hereinafter set forth.
The object of the invention is to let 0E the air which collects in the radiator, owing to change in the temperature'of the water, and to accomplish this object in an automatic manner.
In the accompanying drawings the letter ct designates the wall of a hot-water radiator, and b a tubular valve-box adapted to b e secured in a threaded aperture c of said Wall by means of its threaded end d. The valvetube or valve-box h is provided with a vertical tubular offset e, extending upward from the outer portion of such valve-tube or valvebox and open at the top. This offset tube or chamber e is threaded at its upper end and provided with a threaded cap or stop f, which is fastened ou its under side as a valve-seat g. This underside or bottom of the stopf 1s made concave, and the apex of the concavity communicates with a small aperture or perforation h, which is the outlet for the air. The tubular odset or chamber eis made long enough to allow play'to the rloosely-sliding piston-form block k, which is made, preferably, of hard rubber.V` The top of this block is made concave, as at 7c', as is also the bottom at k2, and its form is that of a cylinder, having, however, one or more grooves or an air-passagec3 along its side. This block is designed to fit looselyin the tube, so that it will readily move up or down therein, the tubular wall forming a guideway to keep the block in upright position.
The top of the block or plunger 7c is entirely concave from lits outer edge to the center, this concavity being of bevel form, as
shown. Upon the concave top of the block restsv a small ball-valve l of smaller radius than said concave top, which is stemless. This ball-valve is made of metal, and when it is pressed upward by the block against the Valve-seat ofthe stop f it is centered by the action of the conoavities of the stop and ot the block and closes the aperture h, thereby preventing theescape of the hot water. Whatever may be the position of the ball when the plunger is forced up by the action of the water it will automatically center itself, rolling upon the bevel concavity to its deepest portion, so as to close the valve-opening in the stop. Theplunger, its casing, and ball-valve being entirely loose from each other are designed to avoid any sticking or adhesion of the parts oniaccount of sediment or grime in such wise that the valve will act promptly and will not get out of order. Upon the removal of the threaded cap or cover f the slideblock k and the ball-valve may be removed from the top of the valve-box. The valveloox may also be provided with a positive valve fn, having a threaded engagement with an aperture in the outer end of the valveboX, being adapted to engage a concave conical valve-seat fn, formed in said'box around its tubular base.
When air accumulates inthe valve-box in the upper portion of the offset chamber displacing the water the block 7o will fall, allowing the ball-valve to fall, and the air will then escape through the aperture h. The subsequent pressure of the water under the block raises it and also .carries upv the ball-valve and presses it against the valve-seat in the IOO bottom of the stopf, closing the aperture and preventing the Water from escaping. The action is automatic and is designed to avoid the necessity of constant attention in this regard.
The concave bottom of the plunger 7o allows for an air-chamber therein to cause the plunger to oat.
Having described this invention, what I claim, and desire to secure by Letters Patent, 1s
In an automatic air-valve, the combination of a valve box or casing, a removable screwtop for said casing, said screw-top having a central perforation and a concavity on the under side surrounding said perforation, a
