AUTOMATIC FEED-WATER REGULATOR.

SPECIFICATION forming part of Letters Patent No. 618,265, dated January 24, 1899.

Application filed August 4, 1898. Serial No: 687,679. (No model.)

To (tZZ whom it may concern:

Be it known that I, HENRY H. DYKE, a citizen of the United States, residing at Butler, in the county of Butler and State of Pennsylvania,have invented new and useful Improvements in Automatic Feedater Regulators, of which the following is a specification.

This invention relates to devices for automatically controlling the supply of feed-water to boilers; and the object of the invention is to produce an apparatus adapted to receive a constant flow of water from a pump or inspirator, but which will deliver only such part thereof to the boiler as is necessary to maintain the desired water-level therein, dischargin g the surplus automatically through a waste port.

The invention consists in the novel features of construction and in the combination and arrangement of parts hereinafter fully described and claimed, and illustrated by the accompanying drawing, which is a View in elevation of the apparatus, parts thereof being shown in section.

The pipes A A extend from opposite horizontal branches of four-way coupling 13, pipe A leading to a boiler X, and pipe A extending to a pump or inspirator. (Not shown.) Secured by suitable couplings to said pipes are vertical rods or posts 0, which support horizontal pipe D. This pipe taps the boiler at the desired water-level line, and raised therefrom, preferably in line with rods 0, are pipes E, connected at their upper ends by cross-pipe F.

The lower vertical branch of coupling B connects with waste-pipe G, and formedin said branch is valve-seat Z), adapted to be closed by ball-valve II on the lower end of rod I, the latter extending upward through coupling B, as shown, and secured at its upper extremity centrally to pipe F. The reach of rod I is regulated by turnbuckle I.

\V hen the water in the boiler drops below the plane of pipe D, steam enters said pipe and pipes E and F, and when thus heated said pipes expand, the action being that of a thermostat, the elongation of pipes E being sufficient to draw up rod I and seat valve H. The waste-pipe is thus closed, and all water from the pump passes to the boiler, the parts remaining in this last-described adjustment until the water-level rises above pipe D and shuts off the supply of steam therefrom, when said pipe and pipes E and F cool off and contract, and thus lower rod I and open valve H,

so that part of the feed-water is again diverted to the waste-pipe. This operation is repeated automatically whenever the water level falls below the prescribed limit, as will be understood. Thus an unvarying flow of water is utilized to maintain the water at approximately a fixed level, the surplus being discharged automatically at a point between its source and the boiler.

The apparatus is of substantial, yet simple, construction. Rods O hold the lower end of the expanding element in proper relation to the supply element, and rod I, connecting with pipe F midway between pipesE, is given uniform movement for opening and closing the waste-valve.

Cock J may be secured to the outer extremity of pipe D for blowing out said pipe or for removing surface refuse or skum from the water within the boiler. By .closing valve K in pipe D and opening cock J pipes E and F may be blown out.

The apparatus is of such construction that it can be connected at either side to the boiler.

While the pump or inspirator connection is here shown at the extremity of pipe A, it can as well be made at any other point on said pipe or on pipe A, outside of check a, or even to coupling B.

Having thus fully described my invention, what I claim, and desireto secure by Letters Patent, is

1. An automatic feed-water regulator, including a boiler connection adapted to receive a constant inflow of water, a waste -valve therefor, a regulating-pipe tapping the boiler at the water-level line, supports for the regulating-pipe adapted to hold the same fixed with relation to the boiler connection, wastevalve-operating rod I, and pipes extending from the regulating-pipe in direction parallel with said rod and connected thereto, substantially as shown and described.

2. An automatic feed-Water regulator, including a boiler connection adapted to receive a constant flow of water, a waste-valve therefor, rods 0 raised from the connection, pipe D tapping the boiler at the water-level line and supported by said rods, waste-valve-op erating rod I raised above pipe D, thermostatic pipes E raised from pipe D, and a connection between the upper ends of pipes E and rod I, substantially as shown and described.

3. An automatic feed-water regulator, including coupling B, pipes connecting the same to the boiler and to a water-source, a wastevalve for the coupling, a valve-operating rod working through the coupling, pipe D tapping the boiler at the water-level line and having fixed position with relation to coupling 13, thermostatic pipes E connected at their lower ends to pipe D and at their upper ends united by pipe F, the latter being connected to the valve-rod, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

HENRY H, DYKE.
