PUMP-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 766,730, dated August 2, 1904:.

Application filed February 16, 1904. Serial No. 193,902. (No model.)

To (Ll-Z whom, it may concern:

Be it known that I, CHARLEs QUINLEY, Jr., a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of \Visconsin, have invented a certain new and useful Improvement in Punip-Regulators, of which the following is a specification.

My invention relates to a new and useful improvement in automatic pump-regulators, and has for its object to provide a regulator which will automatically regulate the steamsupply to the pump, so that a certain amount of water will always be kept in a tank located at a point above.

\Yith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the artto which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawing, forming a part of this specification, in which is represented a sectional view through my improved regulator and valve of the steam-pipe.

A represents the main steam-pipe supplying the pumps.

B is the valve controlling the steam-supply, the valve-stem B of which extends upward through a suitable stutling-box and is secured at its upper end to a lever C, which lever is pivoted to a standard at the point C.

l) is a cylinder connected at its upper end with a pipe E, leading upward to the tank or reservoir above.

F is a piston titted to slide within the cylinder D, and the piston-rod F extends downward through the lower end of the cylinder and rests upon one end of the lever G. The opposite end of the lever C upon the other side of its pivotal point is provided with an adjustable weight' G. Thus it will be seen that the pressure of the water within the reservoir above through the pipe IE will come in contact with the piston F and always tend to press the same downward; but the weight G is so adjusted upon the lever C that it will counterbalance the weight of the water when said water is at a predetermined level; but should the water rise above the predetermined level the weight of said water being increased will press the piston downward, which in turn will press downward one end of the lever (I, which will close the valve B within the steampipe; but as soon as the level of the water is reduced to a certain point the weight G, overbalancing the weight of the water, will bear down upon its end of the lever C, and thereby open the valve B within the steam-pipe, so that the water may be restored to its normal level within the reservoir. Thus it will be seen that the action of this regulator is entirely automatic and extremely simple.

In the drawing 1 have shown an overflowpipe H leading from the side of the cylinder l), and the mouth of this overflow-pipe is normally covered by the piston; but when the piston F is lowered by the weight of the water the mouth of this overflow-pipe will be uncovered, and the water may flow from the pipe E through the overflow-pipe to the waste. Thus if at any time any of the parts of the apparatus might be damaged there would be no danger of the overflowing of the reservoir, because of the fact that the overflowpipe l-I would reduce the level of the water to the point where the weight of the water would be overbalanced by the weight Gr.

1 is an air-cock for the purpose of drawing the air from the pipe E at any time desired.

Of course I do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of the invention.

Having thus fully described my invention, what .l claim asnew and useful is- Ina device for regulating the supply of water to an elevated reservoir, a cylinder connected at its upper end through a pipe with the reservoir, a piston titted to slide within said cylinder, a piston-rod extending downward through the lower end of the cylinder, a lever pivoted intermediate of its two ends, one end connected to the piston-rod, an adjustable weight secured upon the opposite end of the lever, a steamvalve, the valve-stem of which is pivoted to the lever between its pivotal point and the point of its connection with the piston-rod, an overflow-pipe extending from the cylinder, said overflow-pipe normally closed by the piston but opened when the piston is lowered by an excess weight of water, and an air-valve extending from the pipe leading to the reser- Voir, as and for the purpose specified.

In testimony whereof I have hereunto affiXed my signature in the presence of two subscribing witnesses.
