FEED-WATER RE LATOR.

SPECIFICATION forming part of Letters Patent No. 769,092,0lated August 30, 1904.

Application filed May 25, 1904.

To all whom, it may concern.-

regulators; and the object of our invention is to provide a regulator of this type which is adapted to be used in connection with a boiler whereby should the level of the water in the boiler reach a dangerous point another supply of water will be admitted to said boiler.

1 Y Another object of our invention is to provide a feed-water regulator which is adapted to control the operation of the pump which supplies water to a boiler, and we have pro- -vided novel means in connection with the regulator whereby should the level of the water within the boiler reach a dangerous point occasioned by a small supply of water within the boiler.

. The construction employed to accomplish ,the above objects will hereinafter be more fully described, and specifically pointed out in the claims. 7

In the drawings forming a part of this application like numerals of reference indicate like parts throughout the several views, in which- 7 Figure 1 is a side elevation of our improved water-regulator as applied to a boiler, a part of the regulator and boiler being shown in section. Fig. 2 is a vertical sectional view taken on the line 00 00 of Fig. 1, and Fig. 3 is a top plan view of one of the cylinders forming a part of our improved regulator.

Referring to the, drawings accompanying this application, the reference-numeral 1 indicates a boiler of a well-known type which is mounted in the brickworksupports'2, and

upon the top of said boiler we have mounted a stuffing-box 8, through which is adapted to Serial No. 209,709. (No model.)

operate a rod 4, upon the lower end of which is mounted a float 5, this float being adapted to be supported upon the surface of the water in the boiler, and formed integral with the upper end of this 'rod is a rack-bar 6, which passes through a guide-yoke 7, carried by an annular casing 8, said casing having its one side cut away, as indicated at 9, and this casing is secured by screw-bolts 10 upon cylinders 11 11, which are secured by any-desired means to the valve-casings 12 and 14:.

The cylinders 11 11, as shownin Fig.- 3 of the drawings, are made of two sections and are provided with recesses 1515, formed in their ends, and the neck portions 16 16 of the cylinders 11 11 are provided with screw-threaded openings 17 17, which communicate with the recesses 15 15, and in these recesses is mounted the hub 18 of a gear-wheel 19, which is norends of the rods 22 and 23 pass through the end walls 2 1 24: of the cylinders 11 11 and protrude into the valve-casings 12 and 14:, and in describing the construction of these valvecasings it is only deemed necessary to describe in detail the construction of one casing, as they are similar in construction and perform a like function. Each valve-casing is provided with a flanged portion 25, to which is secured the cylinder 11, and the casing is also provided with the inlet-chamber 26 and the outlet-chamber 27, and separating said chambers is the partition 28, which is provided with an aperture 29, forming a valveseat for the valve 30, which is normally held on its seat by a spring 31, mounted upon the valve-stem 32, said spring 31 being interposed between the valve and the side of the casing,

which is provided with a boss 33, having an formed in the rear face of the valve to receive the pointed end of the rods 22 23 when the same are operated.

Communicating with outlet-chamber 27 is a pipe 35; which is connected to the top of the boiler 1, whereby any steam generated in said boiler will pass through said pipe to the valvecasing 14:, and communicating with chamber 26 is a pipe 36, carrying a valve 37, and this pipe 36 is connected by a T 38 to a pipe 39, which passes to the pump. (Not shown.) From the pump leadsa pipe 40, which is connected by a T ll to a pipe 42, which communicates with the valve-casing 12 in a similar manner to the pipe 36, and the referencenumeral 43 indicates a pipe similar to the pipe 35, which is connected to the bottom of the valve-casing 12, this pipe being provided with a valve 44 and leads to the top of the boiler 1.

The operation of our improved feed-water regulator is as follows: During the formation of steam within the boiler 1 and the consumption of water within the boiler, the float 5 will have a "ertical movement within the boiler, and as the water becomes low and travels toward the dangerous point the downward movement of the float carries with it the rod i, and the rack 6 imparts a rotary movement to the gear-wheel 19, which is mounted within the annular casing 8, and upon the gear-wheel l9 rotating a similar movement is imparted to the screw-threaded rods 22 and 23 through the blocks 21 engaging in the rectangular bore 19' of the gear-wheel 19, and as the rods 22 and 23 are provided with screw-threads we provide the screw-threads on the rod 22 as right-hand threads and the threads upon the rod 23 as left-hand threads, whereby the valves in each of the valve-casings 12 and 14 will be opened, the end of the rods engaging the seats 34 and forcing the valves 30 from their seat, compressing the springs 31, at which time the steam generated in the boiler will pass through the partition 28, through port 26, through pipes 36 and 39 to the pump, operating said pump, whereby water will be forced through pipes 10 and 12 to the valve-casing 12, and the valve in this casing having been opened by the rod 23 the water will pass through pipe 13 to the boiler, refilling the same and cansing the float 5 to rise to its normal position, at which time the valves in each of the valvecasings 12 and 14 are closed, shutting off the supply of water to the boiler and the supply of steam to the pump.

It will be seen that the valves in each of the valve casings are controlled by the rising I and lowering of the float within the boiler and that a slight vertical movement of the float will regulate the valves in the valve-casings,

within the boiler, but may be operated at any time when the fires beneath the boiler have consumed the water therein and caused the float to descend to a dangerouspoint.

It will be noted that any desired form of pump or boiler may be used in connection with our improved water-regulator, and while we have not shown suflicient supports for the pipes and valves it is obvious that any desired means may be employed to support the same, and various slight changes,such as the general arrangement of the valves and their appurtenant parts, may be made without departing from the general spirit and scope of the invention.
