HENRY J. WEISSER, OF POTTSTOWN, PENNSYLVANIA.

AUTOMATIC BOILER-FEED.

SPECIFICATION forming part of Letters Patent No. 521,351, dated J' une 12, 18'94.

Application tiled August 26, 1893. Serial No. 484,113. (No model.)

To all whom t may concern:

Be it known that I, HENRY J. WEIssnR, a citizen of the United States, residing at Pottstown, in the countyof Montgomery,State of Pennsylvania, have invented a new and useful Improvement in Automatic Boiler-Feeds, Which improvement is fully set forth in the following speciication and accompanying drawlugs.

My invention consists ofV anv automatic' boiler feed or feed valve formed of a vessel in communication with the boiler, a ioat in said vessel adapted t0 open a valve therein, and a piston Which is operated by the influx of steam into said vessel, whereby a valve in the feed pipe is opened and the boiler accordingly su pplied, said feed pipe valve afterward closing when the level `of Water is obtained said parts being arranged and combined as hereinafter described.

Figure l represents a partial side elevation and partial vertical section of a boiler feed embodying my invention. Figs. 2 and 3 represent vertical sections of different forms thereof.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings: A designates a steam boiler, and B designates the water supply pipe thereof.

C designates a steam pipe which is connected with the boiler, and with the steamreceiving vessel D, the latter having connected with it the Water pipe E, which is also connected With the boiler, so that the level of water in the boiler will be the samein said vessel.

F designates a Heat which is in the vessel D, the same being hung by the levers F, F2, with the valve G, Whose seat is on the upper wall of the vessel D, and which opens into the box H, within which is the piston J, whose stem K is pivoted to the Weighted lever L, the latter carrying near its axial end the valve M whose seat is on the water supply pipe B below the inlet branch N thereof.

The float F is freely hung on one end of the lever F', so as to at all times maintain its vertical position,- and the said lever is pivoted at its other end to the wall of the vessel D, or an attachment thereof, and is connected by a link with one end of the lever F2, which latter is weighted at its other end, and is pivoted to a hanger on the Wall of the vessel D, the valve G being pivotally connected with said lever between its fulcrnm and the link connection, thereby insuring vertical movements at all times, of said float and valve.

It Will be seen that when the boiler is properly supplied with water, the valve G is closed, owing to the position of the float F. When the Water becomes low, the ioat falls and carries the valve G with it, thus opening communication with the box I-I, and causing the steam which has entered the vessel D through the pipe C to impact against the piston J, and raise the same. This lifts the valve M, and accordingly causes `water to iiow from the branch N into the pipe B, and thus supply the boiler. Vhen the level of Water is attained, the oat rises and closes the Valve G. The piston J now descends, owing to the weighted lever L, and the valve M is closed, whereby the supply of water ceases.

In lieu of the Weight on the lever L, I may employ the spring N which bears against a collar on the stem K, and a yoke or other support Q ou the box H, as shown in Fig. 2.

In Fig. 2, I showboth the weight and spring dispensed with, and in lieu thereof I employ the supplemental steam pipe R, which is connected with the pipe C and box II and communicates with the same. A valve S is placed on said pipe R, and lugs T, T, on the stem K in such manner that when the piston J has risen sufficiently, the lug T engages the arm T2 on the stem of the valve R, and opens the latter, whereby steam enters the box H, and lowers the piston, the valve M being thereby closed. The descent of the stem K causes the lug T to engage with the arm T2 and close the valve S, and thus the supply of steam through the pipe R is cut oif.

Having thus described my inventiomwhat I claim as new, and desire to secure by Letters Patent, isdl. An automatic boiler feed having a vessel connected by water and steam pipes with the boiler, a water pipe leading into the boiler and having a controlling valve, a valve controlling a steam outlet from said vessel, said valve being connected by levers with a Iioat therein, a box in communication with said steam outlet having a piston therein, a lever ICG connected with said Water pipe valve and with said piston, and a supplemental steam pipe leading from the first mentioned steam pipe to said box on the opposite side of the piston from said steam outlet valve of the said vessel, and a valve in said supplemental steam pipe having an arm engaged by stops on the stem of said piston, said parts being combined substantially as described.

2. The combination of the Vessel D, having steam and Water communication With a boiler, the box H on said lvessel D, the valve G between said vessel and box, the lever F in said vessel, the ioatFfreely mounted on said lever F, the lever F2 having a Weight on one end, and its other end linked to said lever F the said valve G being pivotally connected to said lever F2 intermediate oi' its fulcrum and its linked connection, a piston in said boX, a water supply pipe to said boiler with avalve thereimand a Weighted lever connected to said Water supply pipe valve and to said piston, substantially as and for the purpose set forth.
