IMPROVEMENT IN` Specilication forming part of Letters Patent N o. 189,683,
GAS-REGULATCRS.
dated April 17, 1877; application liled December 23, 1876.
To all whom it may concern:
Be it known that I, JOHN BAssEMIR, ot' the city, county, and State ofV New York, have invented certain new and useful linprovements in Gas Regulators; and l do hereby declare the following to be a full, clear, and exact descriptionthereot', reference being had to the accompanying drawing, and to the letters ofreterence marked thereon.
The nature of my invention consists in the particular construction and arrangement of a as will be hereinafter more fully set forth.
In order to enable Others skilled in the art to which my invention appertains to make and use the same, l willl now proceed to describe its construction and operation, referring to the 'annexed drawing, which forms a part of this specilication, and which represents a central vertical section ot' mygas-regulator.
A represents the shell or case Ot' my gasregulator, provided with a suitable cap or cover, B. In the bottom of the shell A is the gas-inlet L, and in the side ot' said sh'ell is the outlet O. l
Directly above the inlet L within the shell is an annular conical flange or cone, P, in which the valve-seat l) is screwed down from the top, as shown. Below this valve-seat is the valve E, provided with the npwardly-projecting stem Kf The valve E isin the form of an inverted bowl, or, in other words, the one-halt' ot'a hollow sphere, and the inner diameter ofthe valve at its bottom is larger than the diameter ot' the gas-inlet, so that the full force of the entering gas will act on said valve, as the entire column will pass within the valve before it is checked and commences to spread around the sides thereof, and pass up into the body of the regulator and out through the outlet.
Near the top ot' the shell A is an interior ich, by means of screws b b, are fastened a flexible diaphragm, F, and an annular plate-ring', d, on top thereof, at the edges. These screws b also fasten an interior cap, '0, elevated above the diaphragm, as shown.
To the center of the exible diaphragm F are secured top and bottom plates I I, and in the centerl ot' said plates is arranged a stuffing-box, h, through which the valve-stem K passes, and in which said valve-stem is fastened. The upper end of the valve-sten1 passes through a hollow screw, G, which is screwed downward through the center of the interior cap C, and forms a guide for said stem. This screw G also regulates the pressure otaspring, H, which is placed around the valve-stem, be tween said screw and the stningbox It, l'or holding the valve E open.
The spring H is to be regulated to acer-tain pressure of gas, to allow the gas to pass around the valve E into the lower chamberof I the shell and to the servicepipes through the outlet'O. When increases, such upward, dimin ever the pressure of the gas pressure forces the valve E ishing the aperture through which the gas Hows; and as soon as the pressure is reduced the spring lowers the valve to increase the size ot' said aperture, and thus always maintain the same pressure in the service-pipes. The valve E being in the form shown, and above and of larger diameter than the inletpipe, the entire column of gas strikes the iuterior of the valve, and makes the saine very sensitive to the slightest variation in the gaspressure. As constructed, the diaphragm is entirely inclosed, and cannot be tampered with by lifting ott' the outside cover.
J .is simply a clean-out opening.
Having thus fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is-
'lhe combination Ot' the shell A, with cover B, annular ilange P, with adjustable valveseat D, semi-spherical valve E, with stem K, llexible diaphragm F, with plates l and stuffing-box h, and the spring' l-l, interior cap (l, and'regnlating-screwG, all substantially as and for the purposes herein set forth.
