CHARLES OSKAR BER-GMARK, OF CHICAGO, ILLINOIS.
FEED-WATER REGULATOR.
Application fiIecl September 15, 1903.
T 0 all whom "it may concern:
Be it known that 1, CHARLES O. BERG- MARK, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Feed-Water Regulator, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved feed water regulator, more especially designed for regulating the flow of the feed water into a boiler or the like, and arranged to maintain water in the boiler at an approximately constant level.
For the purpose mentioned, use is made of a controlling device in the feed water supply and normally open, and an automatic means connected with the said controlling device and actuated by pressures of steam derived from the boiler, the pressures when equal holdin the said controlling device open to allow the boiler to fill with water, and when the latter reaches a predetermined level in the boiler then one steam pressure is reduced by condensation of the steam and the said controlling device is closed.
A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification, in which the figure is a sectional side elevation ofthe feed water regulator as applied to a boiler and its feed pipe.
A boiler A, of any approved construction is supplied with water by means of a feed pipe B connected with a pump or other source of water supply. The flow of the water through the feed pipe B is controlled by a valve 0 of any approved construction, and normally open by the action of a spring D pressing a rod E pivotally connected with an arm E attached to the stem G of the valve C. The rod E is mounted to slide in a lug F of a frame F attached to the casing O of the valve C, and the spring D above mentioned rests with one end on the lug F and presses at the other end on a nut E secured on the rod E, to hold the valve C nor mally open. By adjusting the nut E the tension of the spring D can be regulated.
A diaphragm chamber G is attached to or forms a part of the frame F, and is provided with a diaphragm H secured to the stem O, dividing the chamber G into compartments G of which the compartment G is connected by a pipe I with a pipe J leading to the steam compartment A of the boiler Specification of Letters Patent.
Patented June 14, 1910.
Serial No. 517,806.
A. The compartment G of the diaphragm chamber G is connected by a pipe K with the upper end of a condensation chamber L, connected at its lower end by a pipe N with the water compartment A of the boiler A. Into the upper end of the condensation chamber L leads a channel L, connected at its lower end with a pipe 0 extending into the upper portion of a controlling chamber P, connected at its bottom by a pipe P with the pipe N and hence with the water compartment A of the boiler A. Into the top of the controlling chamber P also opens a short pipe J 2 extending from a tee attached to the pipe J, and through which tee J extends the pipe 0, as plainly indicated in the drawing.
The controlling chamber P is arranged 0pposite the boiler A, while the condensation chamber L extends above the same and the pipe O extends into the controlling chamber P such a distance that its lower end is level with the intended level of the water in the boiler A. By the construction described and shown the controlling chamber P is filled with water from the boiler A to the same level as that of the water in the boiler A, and the water in the controlling chamber P rises and falls with the water in the boiler A. Now as long as the water in the controlling chamber P uncovers the lower end of the pipe 0, it is evident that steam passes by way of the pipe J, tee J, pipe J upper end of chamber P, pipe 0, channel L, condensation chamber L and pipe K into the compartment G of the diaphragm chamber G, so that the pressure on both sides of the diaphragm H is approximately equal as both chambers G and G are now directly connected with the steam compartment A of the boiler A, and hence the spring D holds the valve G in normal open position, whereby water flows into the boiler A. Now as the water rises in the boiler A it also rises in the chamber P and finally submerges the lower end of the pipe 0. When this takes place, the compartment G of the diaphragm chamber G is cut off from the steam compartment A of the boiler A, and as the steam in the condensation chamber L now condenses, the pressure is reduced in the said chamber L and in thevcompartment G so that preponderance of pressure in the cham ber Gr forces the diaphragm H to the left, thus moving the valve G into a closed position and thereby cutting off the water supply from the boiler A. When the level of the water in the boiler A and the chamber P falls until the lower end of the pipe 0 is uncovered, then steam from the boiler A can again pass by way of the pipe 0 and channel L into the condensation chamber L, by way of the pipe K into the compartment G thus equalizing the pressures on the diaphragm H, to allow the spring D to again move the valve G into an open position.
From the foregoing, it 'will be seen that I by the arrangement described, the valve C is held normally open for filling the boiler A with water, and when the predetermined level is reached the valve C is automatically closed as the preponderance of pressure in the compartment G causes movement to the left of the diaphragm H, as before eX- plained, and when the pressures are again equalized in the chambers G, G the diaphragm returns to normal position and with 1t the valve C by the action of the spring D.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. A feed water regulator, comprising a feed water supply, a valve in the water supply having a stem, a spring for normally holding the valve open, a diaphragm chamber having a diaphragm connected with the valve stem, the said diaphragm dividing the chamber into compartments, a pipe leading from the steam compartment of the boiler, a pipe connecting said pipe with one of the compartments of the diaphragm chamber, a condensation chamber connected at its upper end with the other compartment of the diaphragm chamber and connected at its lower end with the water compartment of the boiler, a controlling chamber connected at its upper end with the pipe leading from the steam boiler, and at its lower end with the water compartment of the boiler, and a pipe eX- tending into the upper end of the controlling chamber and connected with the upper part of the condensation chamber.

4. A feed water regulator comprising a feed water pipe connected with the boiler, a valve in the feed water pipe and provided with a stem, an arm on the stem of said valve, .a rod connected with said arm, and mounted to slide, a spring on said arm, means for regulating the tension of said spring, a diaphragm chamber having a diaphragm dividing the chamber into compartments, one of said compartments being directly connected with the steam compartment of the boiler, the said valve stem extending into the other compartment of the diaphragm chamber and connected with the diaphragm, and means controlled by the fall and rise of water in the boiler for connecting and disconnecting the last mentioned compartment of the diaphragm chamber with the steam compartment of the boiler, t 1e said spring permitting the valve to close when the said compartment of the diaphragm chamber is cut off from the steam compartment of the boiler, and holding the valve open when both compartments of the diaphragm chamber are directly connected with the steam compartment of the boiler.
