UNITED STATES PATENT OFFICE.
THOMAS MCNEIL, JOHN MCNEIL, AND HUGH MERRIE, CINCINNATI, OHIO.
FLUID-PRESSURE REGULATOR.
SPECIFICATION forming part of Letters Patent No. 457,056, dated August 4, 1891. i Application filed January 9, 1891. Serial No. 377.219. (No model.)
To all whom it may concern:
Be it known that we, THOMAS MCNEIL, JOHN MCNEIL, and HUGH MERRIE, all citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Fluid-Pressure Regulators; and we do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the annexed drawings, which form part of this speciiica` tion.
This invention relates to those fluid-pressure regulators which include a pair of communicating cylinders of unequal diameters having an inlet at one end, an outlet at the other end, a seat for a valve to close against, and a hollow water-way that carries said valve, and also a pair of pistons, one for each of said cylinders; and our improvement comprises 'a novel construction ot' the pistons proper, the details thereof being hereinafter more fully described, and then pointed out in the claim.
In the annexed drawings, Figure l is an axial section of our fiuid-pressure regulator, the valve of the same being closed. Fig. 2 is a horizontal section of the device, taken at the line Z Z of the preceding illustration. Fig. 3 shows the method ot applying our'regulator to the ordinary water-pipes of a building.
A and B represent a pair of communicating cylinders of unequal diameters, the lower or smaller cylinder Bhaving an inlet (l, while the upper cylinder A has acap D screwed or bolted to it, said cap being provided with a discharge or exit E. The lower end of the small cylinder has a :raised seat or other appropriate bearing F for a disk-valve G, attached io a hollow water-way H, having near its bottom one or more inlet-ports I I. Located above the valve G are radial arms J, (more clearly seen in Fig. 2,) and above these arms a disk K is placed, which arms and disks are preferably integral with the water-way H.
L is an inverted cupped packing, so fitted between the arms J and disk K as to expand outwardly by any upward pressure of water within the cylinder B. These parts are duplicated for the upper cylinder, M being a series of radial arms, N a solid disk, and O a of water within cupped packing, which latter is arranged in a reverse manner to the packing I., so as to expand outwardly by any downward pressure cylinder A.
P are holes for draining olf any leakage that may occur at either of the packings L or O.
R in Fig. is a pipe attached to the inlet O and communicating with a street-main or other source of supply, and S is a pipe coupled to the exit E and carried up through a buildlng.
T, T, T, and T are cocks or other connections attached to pipe S and adapted to deliver water on the different floors or flats of said structure. Vhen the various operative parts of our regulator are in their normal positions, as seen in Fig. l, the valve G is closed against the seat F and will remain in this condition until either one of the cocks T is opened. As soon, however, as a ventage is thus afforded for the pipe S, the valve Gis instantly'raised from oit its seat, and water then flows into the cylinder B, passes through the ports I I into the water-way H, and ascends the exit E and its connection S. The water then finally escapes through the open cock. Vhen sufficient water has been drawn off, the cock is closed, and owing to the excess of pressure that now accumulates upon the piston O N ofthe larger cylinder A the moving water-way H is forced down until its valve G is again firmly seated on the bearing F, which act automatically cuts off all communication between the inlet R and discharge S.
As soon as valve G is opened the pressure of water within the cylinder B readily and instantly expands the cupped packing' L and prevents leakage, which free expansion is due to the fact that said packing is unusually flexible on account of it not being clamped at its center to the disk K. The packing is `held in place merely by the radial arms J,
which permit the water to press against the entire exposed surface of the cupped device I.; but when said valve is closed the upper radial arms M permit the water to expand the other packing O. It will thus be seen that the various arms J M proventdisplacement of the respective packingsL O and yet permit their ICO exposed surfaces to be subjected to the full head. orl pressure of water only when such pressure is necessary to keep the pistons water-tight. wear and tear of said packings or pistons.
WV@ claim as our invention- The combination, in a fluid-pressure regulator, of a cylinder A, having a discharge E, a cylinder B, of relatively less diameter than the former and communicating therewith, which cylinder B is provided with an inlet C and valve-seat F, and a hollow water-way H,
' having a valve G at one end and a port I near said valve, said Water-way being provided Therefore there is no unnecessary with a pair of disks K N, two sets of radial 15 arms JM, and reversely-cupped packings L O,which arms bear on the outer edges of said cupped packings, in the manner described, and for the purpose stated.
In testimony whereof We affix our signazo tures in presence of two witnesses.
