SPECIFICATION forming part of Letters Patent No. 452,97 5, dated May 26, 1891.

Application filed December 23, 1890. Serial No. 375,643. (No model.)

To all whom, it may concern:

Be vit known that we, SAMUEL K. WAGNER- and HARRY T. BENNETT, citizens of the United States, residing at Latrobe, in the county of Vestmoreland and State of Pennsylvania, have invented a new and useful Feed-Water Regulator, ot which the following' is a specification'.

This invention relates to feed-water regulators for controlling and regulating the supply of feed-water to steam-boilers; and ithas for its object to provide a device of this class which shall be simple in construction, by which the supply of feed-water shall be automatically regulated, and which shall be adapted to sound an alarm when for any reason the pump or injector shall fail to operate, thus causing the water to sink below the safety-line.

With these endsin View the invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective View showing a boiler to which our invention has been applied, a portion of the boiler-casing having been broken away for the purpose of showing the construction more clearly.- Fig. 2 is a vertical sectional view taken longitudinally through the stem carrying the valve, whereby the admission ot feed-water is controlled. Fig. 3 is a sectional View taken on the line 3 3 in Fig. 2. Fig. 4 is a longitudinal vertical sectional View illustrating a modification, which consists in dispensing with the check-valve 9.

Like numerals of reference indicate like parts in all the figures.

1 designates a cylindrical tubular casing, whichis provided near its outer end with flanges 2, by means of which it may be bolted upon the boiler 4, the side ot which is provided 'With an opening 5 for the admission of the inner end of the casing 1. The latter is provided near its outer end with a screwthreaded flange opening 6, with which the feedwatersupply pipe 7 is to be connected. Near its inner end the casing l has a U- shaped pipe 8, at the upper end of which is mounted a ball check-valve 9 confined within a suitable cage 10. communicates with the U-shaped pipe 8, is ground to form a scat for a valve l2, which is mounted upon a tubular stern 13, the outer end of which extends through the outer end of the casing 1, which is provided with a packing-gian d 1i to make a steam-tight joint.

15 designates a solid stem, which extends through the tubular stem 13 and through the plug of cap 10 at the inner end of the casing 1. The outer end ot the stem 15 has an annular tlange 17 bearing against the outer end of the tubular stem 13, withlwhich it is connected by a cap-nut 18. The extreme outer end of the stem 15 extends through the nut 18 and is provided with an arm or lever 19, secured thereon by means of a set-screw 20. The inner end of the stein l5, which projects through tlie plug 16, carries an arm or lever 21, provided with a float 22. In addition to the nut 1S a set-screw 23 may be used for the purpose ot' connecting the stem l5 with the tubular stem 13.

23 designates an alarm-whistle suitably attached to the boiler, and the operating-lever of which has a depending rod 25 lying in the path of the arm or lever 19. The latter is provided with a counterbalance-weight 2G, which is adjustably mounted thereon and which balances the iioat 22 so as to insure the easy operation of the device.

The operation and advantages of lthis invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. Then the water in the boiler falls below the desired point the float sinks, thus causing the tubular stem 13, which is connected by the nut 18 with the stem 15, carrying the float, to rotate, thus operating the valve and admitting the feed-Water through the pipe 7, casing 1, and pipe S. The check-valve 9 prevents backpressure. Vhen the water rises in the boiler, the operation is reversed and the opening 11 is closed by the valve 12. Then for any reason the water-feeding mechanism fails to operate and the water sinks below the safetyline, the arm or lever 19 will be raised far enough to strike the rod 25 and sound an The opening 11, which IOO alarm. It the tubular stem carrying the valve 12 lshould become displaced, it may-bc readily adjusted by simpl y loosening the nut 18 and Set-screw 23, (when the lattei is used,) thus permitting the tubular stem to be adjusted t0 any desired position with relation to the solid stein 15. In case repairs should be necessary the tubular stem carrying the valve 12 may be turned to such a position as to uncover the opening 11, and the supply of feedwater may then be controlled by means of an ordinary globe-valve. Owing to this construction the tubular valvecarrying stem may also be readily adjusted with relation to the iioat-carryng stem without removing the device from the boiler, so as to regulate the admission of feed-water at any desired point.

lVhen desired, the check-valve 9 may be dispensed with, and the device may then be used to regulate the outward passage of steam for the purpose of operating the water-feeding mechanism. This construction, as shown in Fig. et, will involve no change in the general construction and operation of the device.

Having thus described our invention, what we claiin`is- 1. In a device of the class described, the combination of a tubular casing having openings near its inner and outer ends, a tubular stem mounted in said casing and carrying a valve adapted to close one of said openings,A

a stem extending through and connected with said tubular stem, a lever mounted upon the said inner stem and carrying a float, and an arm or lever mounted upon the outer end of said stein and carryinga counter-weight, substantially as set forth.

2. In a device of the class described, the combination of the tubular casing having openings near its inner and outer ends, a tubular stem mounted in said casing and having a valve adapted to close one of said openings, asolid stem extending through the tubular stem or casing and having an arm carrying a iioat, and means for adjustably connecting the said tubular with the said solid stem, substantially as set forth.

3. I n a device of the class described, the combination of the tubular casing having openin gs near its inner and outer ends, a tubu- 4:. In a device of the class described, the* tubular casing having the openings near its inner and outer ends, in combination with the tubular stem carrying a valve, a solid stem connected adjustably with said tubular stem and carrying a iioat and a counterweighted arm, and a U -shaped pipe connected with the opening at the inner end of the casing and having a check-valve at its upper end, substantially as set forth.

5. In a device of the class described, the combination of the tubular casing having openings near its inner and outer ends, the tubular stem mounted in the outer end of said casing and carrying a valve adapted to close one of the openings in the latter, a plug or cap at the inner end of said casing, a solid stem extending through said tubular stem and through the plug or cap and provided near its outer end with an annular flange or collar bearing against the outer end of the tubular stem, the cap-nut connecting the solid stem adj ustably with the tubular stem, a lever mounted upon the inner end of the solid stem and carrying a iioat, and a counterweighted arm secured at the outer end of said solid stem, substantially as and for the purpose set forth.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
