UNITED SAMUEL s. INeALLs, or oHIcAeo, ILLINOIS.

IMPROVEMENT IN GAS-REGULATORS.

Specification forming part of Letters Patent No. 163,0l4', dated May 11, 1875; application tiled March 11, 1875.

.To all whom it may concern Be it known that I, SAMUEL S. INc-ALLs, of Chicago, in the county of Cook and State ot Illinois, have invented a new and useful Improvement in Gas-Regulators, of which the following is a specification:

The object of the present invention is to provide more substantial and convenient means for regulating the low of gas from gas-meters to burners.

The nature of the present invention consists in a valve-rod extended through the bottom of the case, for the treble purpose of forming a bearing at the lowest extremity, providing means for balancing the inverted cup, and locking the valve on its seat to shut olf the gas; and, further, in combination with these elements, upper guides for giving' the cup an accurate vertical movement. y

In gas-regulators a very delicate movement ot' the cup is required to insure an even dow of gas, and one bearing is found insuflicient, inasmuch as any swerving of the cup causes a leverage on such bearing, and therefore prevents an even movement ot the cup.

l am aware that inverted cups and valves in gas-regulators have been before 1 sail; I therefore limit myself to the claim annexed.

In the drawings, Figure l is a long it i-dinal section of my im provementin gas-rei` u.ators;

Fig. 2, a vertical section taken transversely to Fig. l; Fig. 3, a horizontal sectional view taken just above the valve.

A represents a cylinder, which, for a threelight meter, is made of about three inches in diameter, or about twice the size shown. For other meters of a greater number of burners, the regulator is to be made proportionately larger. To the bottom E of the cylinder A is attached a pipe, C, which serves to sepa-rate the valve-rod D from the fluid, and to admit air into the iiuid-chambembetween A B and B and G. VInside of the cylinder A, and around the pipe C, and over the pipe, is placed a cylindrical cup,'B, with a closed upper head, which is attached to the valve-rod-'D at M,

and by means of said rod a lever, H, on fulcrum J, and an adjustable Weight, I, is balanced, so as to give any desired pressure of gas. Water, glycerine, or water and glycerine, or other suitable duid, being putin the cylinder A by means ofa plug, Z, to about two-thirds full, is used with the mechanism named for accomplishing this purpose. R represents a gas-chamber, which receives its supply from a pipe, U, entering1 the fluid-chamber by means otl a valve, N., which is connected tothe valverod D by a link, I. The valve-seat is shown `at O in the bottom of the chamber It, and is ot' any suitable construction. Gas, after passing through valve N, extends into an upper chamber, a, from whence it escapes through a pipe, V. .A hole is formed at the bottom of pipe G for the escape of any liuid \vhich, by accident or otherwise, may come in at the top ot' the pipe. A cup placed on the bottom part lV is used to catch such escaping fluid or es-4 caping gas.

To shut oii' the gas a key, K, is put under the bottom E, and above a pin, S, on the rod D, whereby the latter is drawn down, so as to shut the valve N.

To guide the inverted cup B in its 'vertical' reciprocating movement, guide-rods Q Q are fastened to the top thereof, and slide in a bar, T, attached to the chamber It, the rod D guiding the lower end of the cup.

In practice Vthe apparatus is attached to the meter by mea-ns of a pipe, U, and the servicepipe is attached to the pipe V. The pressure ot' gas is regulated by moving the weight l on the lever H.

I claim and desire to secure by Letters Pntent- The valve-rod D, extended through the bottoni of the case, in combination with the cup B, upper guides Q Q, weighted lever H I, key K, and pin S, as and for the purpose set forth.
