IMPROVEMENT iN GAS-REGULATORS.

Specification forming part of Letters Patent No. 142,155, dated August 26, 1873 application filed May 17,1873.

To all whom it may concern.-

Be it known that I, CHARLES H. ED- WARDS, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful and Improved Gas-Regulator; of which the following is a full, clear, and exact description, which will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawing forming a part of this specification, and in which- Figure 1 is an elevation of my improved regulator; Fig. 2, a vertical central section thereof; and Fig. 3, a top or plan view of the lower part of the bulb.

The object of my invention is to cause a more even flow of gas at the burner; and to that end my invention consists in arranging in the supply-pipe, between the meter and the burner-preferably near the meter--a porous diaphragm and a weighted valve, operating in connection with each other, and constructed and arranged together substantially as hereinafter described. It also consists of the regulator device as a whole, as a new article of manufacture.

In the drawing, A represents a spherical bulb, made in two separate parts, A and A, united to each other by means of a screw attachment, and provided with screw-threaded tubular projections, by means of which it may be readily applied to the supply-pipe. B is a suitable packing, arranged between the parts A and A. C is an annular shoulder or flange projecting inwardly from the part A. D D are diaphragms of fine wirecloth. E E are thin layers of cotton or cotton batting, or other equivalent material, arranged between the diaphragms D D; and F is a diaphragm of haircloth, arranged between the layers E E. The diaphragms D D and F, and the layers E E, are of such diameter as to be supported on the flange or shoulder C.

The diaphragm F is not essential; but I deem it preferable to employ it, for the reason that it increases the firmness of the whole diaphragm without destroying its porous and yielding or flexible features.

Any or all of the diaphragms D D and F may be made either of hair-cloth or of wirecloth.

G is a valve, somewhat less in diameter than the diameter of the opening surrounded by the flange or shoulder C.

I deem it preferable, but not essential, to make the valve Gr dish-shaped, and to arrange its concave face downward, as shown.

gis a stem or pin attached to the central part of the valve G, and passing through the center of each of the diaphragms D D and F. g is a weight attached to the lower end of th stem g.

When the device is made large, and there is danger that the weight y will draw the di- -aphragms from their seat, the flange C may he provided with radial supporting arms, as represented in Fig. 3.

It will be observed, from the foregoing description, that an irregular pressure of gas at the meter will not act immediately on the flame, for the reason that an uneven pressure will be resisted, to a great degree, by the passage of the gas through the regulating device, and that a flickering light will be thus prevented.

Having thus described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination and arrangement, in a 'gas regulator, of the diaphragms D, layer E,

and weighted valve G, all substantially as and for the purposes specified.

2. The combination and arrangement, in a gasregulator, of the diaphragms D D and F, layers E E, and weighted valve Gr, all substantially as and for the purposes specified.

3. As a new article of manufacture, a gasregulator consisting of the parts A and A, diaphragms D, layer E, and weighted valve G, all constructed and arranged together substantially as shown and described, and for the purposes set forth.

CHARLES H. EDWARDS.
