FLUID-PRESSURE GOVERNOR.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application flied July 15, 1910. Serial No. 572,214.

To all whom it may concern:

Be it known that I, MATHEW J. WEBER, of Columbus, in the county of Franklin and .State of Ohio, have invented certain new and useful Improvements in Fluid-Pressure Governors; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

i This invention relates to improvements in pressure governors and more particularly to such as are adaptable for use in automatically controlling the operation of a water lift.

It has been heretofore proposed, especially when the city water pressure and supply are not at all times adequate, to provide a water pressure from the city main and connected with a cistern in a manner to supply the plumbing system of Water. Heretofore, water lifts have usually been installed on the direct pressuresystem and after they have been in use for some time and the cup leathers have become Worn,- the pressure water would continue to go to waste even after the operation of the lift had been stopped. I

The object of my 'present invention is to provide simple and efiicient automatically operated means for preventing waste of water in a system of the type to'whieh allusion has been made, and for preventing all unnecessary o eration of the water lift.

A further 0 ject is to so construct a governor that it will operate automatically to stop the operation of the water lift when a predetermined pressure shallhave accumulated in the plumbing system or in a compression tank embodied in such system.

A further object is to provide'simple and etlieient means for adjusting the governor different pressures and conditions.

With these objects in view the invention consists in certain novel features of construction and combination of parts as herein after set forth and pointed out in the claims.

arged sectional view of the governor, and

ig. 3 is an enlarged transverse sectional View of the governor on line of Fig. 2.

1 represents a water lift of any preferred form of construction, comprising a pump 2 and a water motor 3 for operating the pump, water for operating said motor being supplied from' the city water main indicated at 4., and between said main and the water lift, my improved governor is located, as indicated at In constructing the governor I employ a members 67. valve casing 8 is secured to the member 6 and from this valve caslng, a pipe 10 proects and is connected with the water inlet of the motor member of the lift. Said valve casing is also provided with a threaded nipple 11 for the connection of one end of a pipe 12 provided with a valve 13 and the other end of said pipe 12 is connected with the supply pipe 4. The member 7 of the governor casing is provided interiorly with grooves 13 for the reception of lugs 14 proecting from a head 15 at one end of a threaded shank or sleeve 15 which projects through one end of the casing member 7 and is threaded into the casing member 6. The casing member (3 is provided at one end Xvith a hollow head 16 threaded interiorly and adapted to surround the adjacent end of the casing member 7. An annular nut- 17 is loosely mounted on the casing member 7 and prevented moving past the end of said member 7 by an annular shoulder 18 at the end of said member. This annular nut is adapted to screw into the hollow head of the member (3. Thus it will be seen that the casing member 7 is revolubly mounted on the casing member 6 adjustment of the valve devices as hereinafter explained.

passes through the casing 22 having an annular seat 23 therein and also having an internally threaded flange 2 1. A disk 25 is screwed on the e.;d of the valve rod 19 within the hollow enlargement 22 of easing member 7 and constitutes an abutment for one end of the spring 21. This disk also forms a seat for the central for the purposes of and contains a valve seat 9 is provided at "one end:- engage the seat 9 1n the portion (if a flexible dia hragm 26, the peripheral portion of sai diaphragm being seated onthe annular seat 23 within the hollow enlargement 22. The threaded end of the valve rod passes through thecenter 5 of the diaphragm 26 and is provided with a clamping nut 27. A cap 28 is screwed into the threaded flange portion of the hollow enlargement suitable bushing for the passage of a p1 e section 29, and on which pipe section, tie revoluble member of the governor can turn.

From ,the construction and'arrangement of parts above described, it will be seen that when the overnor member 7 is turned, the threaded s eeve will also be turned and as the construction is such that the governor members 6-7 are not relatively movable longitudinally, the said threaded sleeve 15*? will be caused to move longitudinally and thus djust. the tension of the spring 21 so as t require a eater or less amount of pressure against t e flexible diaphragm 26 to move the valve rod 19 and seat the valve 20. Thedevice can thus be adjusted easily by turningone of the casing members, to suit varying pressures and conditions.

The water inlet for the pump member of thef lift is suitably connected with a piston (not shown) and the outlet of said pump member is connected by means of a pipe 30 with the pipe 29 and, by means of a pipe 31 with the pipe 4,-s aid pipe 31 being provided with a valve 32. The pipe 4 is provided, between the pipe 12 and 31, with a valve 33 and said pipe 4 is connected, beyond the pipe 31, by means of a pi e 34 with a compression tank 35. This tanli is provided with an outlet 36 having water distribution pi es connected therewith, as indicated at 37 ith the valve 33 closed and the valves 13 and 32 open, water will flow from the city main 4 through the pipe 12, past the valve of the governor and through the motor mem- 5 her of the lift for o erating the same. During the operation 0 the pump member of the lift, water will be elevated from this system and caused to flow through the pipes 30, 31 and 34 to the compression tank 35 and from the latter to the distribution pipes of the plumbing system. The pump will continue to operate until the pressure in the compression tank and plumbing system reaches a degree which will overcome the combined pressure of the spring 21' and the water in the city main 4, at which time pressure against the diaphragm 26 will move the valve rod longitudlnally and close the valve 20 on its seat, thus com letel stopping the supply of motive flui I to t e motor member of the lift and therefore promptly stopping the latter. When pressure in the compression tank and plumbing system shall have been reduced as by drawing water from one or more of 't e faucets in the plumbing system) pressure 22 and provided with a against the diaphragm 26 will be relieved and the valve 20 permitted to leave its seat and thus open communication between the city main 4 and the motor member of the lift to permit the renewed operation of the latter. lVith the use of my improvements the waste of water will be avoided and unnecessary wear and tear on the lift will be obviated thus minimizing water bills, repair bills as well as annoyance by noise occasioned 5 by the continuous operat1on of the pump and engine during the night.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is,-- 8
