TO ALL WHOM IT MAY CON GERN:

Be it known that I, Wanna A. Smonns, of Boston, in the county of Sufiolk, and State of Massachusetts, have invented a new and useful Improved Gas-Regulator and Ida hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1, is a vertical section.

Figure 2, an elevation of the valve-chest.

Figure 3, a section of the valve-chest.

Like letters indicate like parts in all thefigures.

This invention is of a new regulator for the pressure of gas, and is applicable for the ordinary coal-gas of cities. It consists of an iron cylinder, A, into which: gas enters through pipe 13 and valve-chest G, and from which it is delivered for consumption through pipe D. This cylinder has a cover, E, which is locked on the outside. An annular groove, G, runs round the periphery of cylinder A, in its interior, which is filled with mercury, and in this'fioets the bell F. To the centre of the dome of this is attached rod k, which fastens by joints i and k, at right angles with each other, a sort of universal couplingto valve 1. This valve slides on plane surfaces on the interior of valve-chest G, is pressed close to the inner surface 0 of valve-chest C by spring m, and closes or opens the triangular opening 1: of chest 0, in plate 0. The apex of the triangle points upwards, thus giving a very quick and sensitive motion to the bell.

The apparatus is eminently qualified for the regulation of the flowof gas. -A triangular opening is -one eminently favorable to regulation of pressure. It presents the maximum of boundary and minimum 'of 'area. The construction of the valve is simple, with no liability to disorder, and the connections between valve and hell are direct, straight, and close. Almost every part is 'a plain casting, and the surfaces to be fitted are-few, and the work on them plain and siu'1pleL. I

A pressure of threeinches of water, or less, is readily reduced by this machine one half, and rendered very equable. To burngas economically and without waste, a comparatively light pressure and free opening are desirable. If the opening be narrow and the passage quick, the gas will rear, and part of it pass ofi' uncon sumcd, This regulator accomplishes what is desired, and is indestructible by the corrosive action of the gas.

I claim as my invention, and desire to secure by Letters Patent- 1. The arrangement of cylinder A, with its interior annular ring or chamber, filled with mercury, and inlet 'and egress-passagesB and D, in connection with fioctingbell F and red It, opening and closing valve Z, in valvechest C, all operating together as and for the purpose.described.

2. The construction of the regulation-valve, consisting of valve-chest C, with its triangular opening 11., in plate 0, and having arranged within it slide I, pressed by spring at, to open or close the said opening, all opersting-together, as and for the purpose described.
