SPECIFICATION forming part of Letters Patent No. 353,776. dated December 7, 18

Application filed December 22, 1885. Serial No. 186,430. (No model.)

To aZZ whom it may concern.-

Be it known that 1, WILLIAM H. BROOKS, of West Point, county of Orange. and State of New York, have invented certain new and useful Improvements in Governors for Circulator- Pumps. of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention has relation to governors or regulators applied in connection with a steamheating or steam-circulating system and the circulator pump or pumps for the purpose of automatically governing the flow of return steatn from the system or works to the pump or pumps by which the water collected in or admitted to the receiving-chamber is returned to the boiler; and the object of my invention is to produce a simple, cheap, durable, and eflicient governor which will operate automatically to control the supply of steam to the pump or pumps at the proper instant, which will obviate the formation of a water seal between the boiler and circulating system, in which all the operating parts are simple and easily accessible, in which provision is made foradmitting live steam to the receiving-chamher for driving the pump or pumps, for admitting water to replace that wasted through leakage and other causes, and for heating the feed-water to prevent the trapping of air in the system, and to secure other advantages, as will hereinafter appear.

To accomplish all of this my improvements involve certain new and useful peculiarities of construction, relative arrangements or combinations of parts, and principles ofoperation, all of which will be herein first fully described, and then pointed out in the claims.

In the accompanying d rawings, forming part of this specification, Figure 1 is asectional elevation of myimproved regulator arranged for application in connection with my steam-oi rculating system. Fig. 2 is a plan of the bottom of the valve-chamber, showing the side walls in section; and Fig. 3is a plan and horizontal section of the lower portion of the regulator. Fig. 4 is a view in elevation, showing one method of applying the apparatus in connection with a set of pumps and a steam-circulating system. Fig. 5 is an outline View showing the ott'set for the rock-shaft of the float-lever applied in the lower shell of the governor.

In all these figures like letters of reference wherever they occur indicate corresponding arts. p A and B are two shells, fitted togetherto form the receiver or main chamber of the governor.

G is a valve-chest applied upon the upper half or section, B, of the receiver, and g is a port or passage establishing communication between the receiver and valve-chest.

D is a float located in the lower part of the receiver, and sustained (when the water is low enough) in proper position upon standards d d, rising from the bottom of the chamber. This float is made of iron or other suitable material, and is counterbalanced so that it will upon the upper or lower shell, and projecting v through the boss to the exterior.

Upon the rock-shaft b the leverF is secured, so that it will rise and fall as the rock-shaft moves under the influence of the float, and upon this lever is an adjustable weight, f, by which the float may be exactly counterbalanced at any desired point of its travel.

The valve G is a simple form of slide-valve having a plane face, and is arranged to travel in the valve-chest upon one side of the port 9, and to open and close the port h, which leads from the valve-chest in one or more directions, according to the number of pumps employed. The valve is shifted upon its seat by an arm, 6, mounted upon a rock-shaft, t, which extends to the exterior of the valve-chest.

A lever, H, is secured to rock-shaft i, and provided with an adjustable weight, j, on one arm, and on the otherarm with a bar or rod, I, connecting it with lever F. The weight j serves to balance the lever H and its connections, and is so adjusted as to make the parts move as easily as possible. Suitable pins, as atkl, are employed for uniting I with H and F.

J J are the ports through which return steam from the works or system is admitted to the governor, and K K are ports through which water (and sometimes steam) is withcoming currents of return steam, water, and air from the system in a downward direction before they can reach the port 9.

At an is asmall orifice leading from the valvechest to the port or passage h. i This orifice is never covered by the valve, but permits the constant flow of a small quantity of steam, just enough to seat the valve or .valves on the pump or pumps, and to cause their pistons to move very slowly, keeping up a forced circulatiou when there is no water to pump.

On the end of the valve G is asmall projection, a, which abuts against the wall of the valve-chest, and prevents the valve from being carried against the wall, leaving it always exposed to steam contact on all faces except return steam enter the receiver at the upperthe bottom.

M is a steam-coil arranged in the waterspace of the receiver, through which live steam is admitted, and N is a water-coil, through which water is admitted whenever necessary to supply the deficiency caused by waste or leakage.

Live steam is discharged into the water in the bottom of the receiver, at or near the bottom, and water is likewise discharged at or near the bottom, the inner end of the watercoil being bent down for that purpose.

At Ois ablow-off orifice, through which any sediment may be discharged.

In Fig. 4, P P are two pumps, of which the suction-pipes K K are properly connected with the water-outlets from the receiver, and J J are pipes conveying return steam from the system to the receiver. These are preferably inclined slightly, so as to properly drain the system. K K are pipes through which the pumps force the water pumped from the receiver back to the boiler Q. Q represents the pipe conveying live steam from the boiler to the heating or circulating system. M is a pipe with valve arranged to admit live steam from the boilerto the steam-coil M, and N a pipe with valve for conveying water from any suitable source.

Of course it will be understood that the pumps, governor and boiler, and the connections required mustbe arranged in accordance with the circumstances of any particular case.

Being arranged substantially as above indi cated, and in connection with any closed system for steam-heating or other circulation, the operation is as follows: Gondense-water and part, the water falling to the bottom, and the steam, after passing the deflector rising through port enters the valve-chest. water rises in the bottom of the receiversufficiently to submerge the float, the latter com- As soon as the mences to rise,losing then about half its weight, so that in the connected system the weight becomes sufficient to compel the movement of the valve far enough to uncover the port h.

Then the steam flows to the pump or pumps,

causing them to withdraw the water from the bottom of the receiver and return it to the boiler. As soon as the water-level is sufficiently lowered, the float descends and the valve is made to travel back again, closingport h.

It will be seen that there is no liquid seal between the system and the boiler. As before explained,a small quantity of return steam is always permitted to escape through m,keeping the pump in very slow motion at all times when the pressureis sufiicient. Air from the system finds its way to the receiver, and thence to the valve-chest and through the pump, and the constant circulation causes the condensewater to flow into receiver at a uniform rate, preventing it from backing up, and thereby avoiding any noise orsnapping, such as usu-- ally occurs in steam-pipes not provided with means for compelling a constant circulation,or such as employ a water'seal which traps the air in the pipes. Live steam can be admitted at any time to the receiver through the steamcoil. The water surrounds the coil and is heated by contact therewith, as well as by the steam when it is discharged into the bottom of the receiver, so that its temperature is raised before being returned to the boiler. By admitting live steam to the receiver the'pump can be started or accelerated at any time. Water admitted to the water-coil is heated before emerging into the bottom of the receiver. It is admitted in sufficient quantities to supply the deficiency caused by leakage, the working of the pumps, the raising oi the safety-valve, &c. All that is necessary is to open the wa ter-valve and the valve in live-steam pipe, and the machine will automatically force the water to the boiler. Attention to the supply of water is all that is required, the governor automatically performing all other offices required of it in the system. The arrangement of ports is such that the top of the governor may be easily dismounted without disturbing the base or water and live-steam connections, and the valve may be easily removed for such attention as it may require. When constructed and arranged for operation substantially in accordance with the foregoing explanations, the improved device will be found well adapted to answer the purposes or object of the invention, as previously'set forth.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a pump-governor of the character herein set forth, the combination of the receiver, the valve-chest, the slide-valve located in the valve-chest upon the top of the receiver, the
