VALVE FOR HEATING-SYSTEMS.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed May 26, 1906. Serial No. 318,8595

To all whom it may concern.-

Be it known that I, ALBERT P. BRooMELL, a citizen of the United States, residing at York, in the county of York, State of Pennsylvania, have invented certain new and useful Improvements in Valves for Heating Systems, of which the following is a description, reference being had. to the accompanying drawings and to the letters and figures of reference marked thereon.

The invention relates to improvements in the valve shown in United States Patent No. 657,059, August 28, 1900.

The objects of the invention are to seat the valve, hold its operating-handle in its locked position, and keep the valve-stem properly packed, all by one and the same spring.

These objects I accomplish by the construction shown in the accompanying drawings, in which Figure 1 is a central vertical section of my improved valve. Fig. 2 is a horizontal sec: tion on line 2 2, Fig. 1. and Fig. 4' is a perspective view, of the valvestem and the disk valve separated.

A designates the valve-casing, having a closed upper end A and there provided with a circular series of recesses a. One side of the casing is provided with a threaded nipple A to connect with the radiator, and the bottom of the casing is closed by a removable externally and internally threaded cap A for connection with the source of supply.

The casing is divided just below the outletnipple A by a transverse partition 0/, having a semicircular slot a, and the center of'the partition is connected with the center of the upper end A by an integral tube a The opening through the partition at the lower end of the tube is reduced so as to forman annular shoulder a to receive the packing material a above which is a washer a. 4

B is the valve in the form of a disk, having an annular recess b in its upper face, within which fits a non-metallic packing-ring b, of asbestos, fiber, or other suitable material. The upper or working face of this packingring projects above the valve-disk B, so that it engages the under side of the partition a and prevents any metallic part of the valve from coming into contact therewith. The periphery of the valve-disk B is spaced from the interior of the casing A. The valve B b Fig. 3 is a plan view,

is provided with a series of circularly-arranged apertures 11 to register successively with the slot or opening a in partition (1/.

The central collar b of the metal disk B is lower than the peripheral or outer flange, and upon it rests the lower shouldered end of the valve-stem which stem passes down through the tube a" and through Washer a, packing a", and annular shoulder a.

The bore of the collar 7) is generally square, but has one corner flattened, as at b, and the squared portion 0 of the valve-stem is similarly flattened, as. at 0, so that the valve-disk must be properly positioned before it can be placed on the stem. When in place, the valve is secured by means of the cap-nut b screwed on the lower threaded end of the stem.

7 O is a sliding flanged 'collar on the valvestem'in the upper end of the tube a and between this collar O and the washer a at the bottom of the tube is placed a spiral expansion-spring O through which the valve-stem works.

D- is the horizontally-disposed handle, pivoted to rock vertically on the upper end of the valve-stem by means of a slot d, through which passes the flattened upper extremity 0 secured therein by a transverse pivot-pin D and causes it to pull upwardly on the stem O, and so hold the non-metallic face I) of the valve B a ainst its seat. -Furthermore, the spring performs the very important function of compressing the packing material a? through the medium of the washer a, and so the valve-stem is kept constantly packed.

The handle is provided .at the lower side of its outer end beyond its pivot with a proj ection (1 which engages the collar O, and at the opposite side of its pivotal point the handle is provided with a depending lockinglug d to engage any one of the recesses a in the up er face of the valve=casing, the upward orce of the spring on projection d tending to press the lug 05 down and hold the handle against accidental displacement. Thus the spring performs the three important functions of seating the valve, keeping the valve-stem packed, and holding the handle locked.

.When it is desired to move one of the valve-apertures If into register with the slot (L2, the handle l) is raised, causing the projection d to-bear down on and depress the collar C, when by turning the elevated handle in the proper direction the valvetwill be rotated to throw the apertures I)- successively into and out of register with the slot (1 thus admitting or shutting oil the lluid to the extent desired.

In order to make these valves suital')l l'or different sizes oi radiators, it is only necessary to change the size of the apertures b in the valve- .lisks and not change the size of the valves themselves. For instance, a So. 1 valve for a radiator of twenty-liw feet heating-surface will have holes one-eighth of an inch, while a No. 2 valve for a radiator of liftv or sixty feet heating-surface will have holes of three-sixteenths of an inch, and so on.' Thus with interchangeable valve-disks valves" of only one size are required for all sizes of radiators.

The valve 1s particularly adapted for use -with the steam-heating system shown in Patent 650,778, May 29, 1900; but it may be used in other relations.

I do not restrict myself to the particular construction shown, since the same may be considerably changed without departing from the scope of my lnvention.

H avingthus described my mvcntion, what I claim as new, and desire to secure by Letters Patent,'is
