IMPROVEMENT IN GAS-REGULATORS.

Specification forming part of Letters Patent No. 158,389,

dated January 5, 1875; application filed October 16, 1874.

To all whom it may concern Be it known that I, AUGUSTUS PARSONS, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Gas-Regulators; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention appertains to make and use the same, reference being bad to the accompanying drawing forming part of this specification, in which Figure 1 is a perspective view of a gas-regulator embodying my said invention. Fig. 2 is a vertical central section of the same. Fig. 3 is an enlarged central section of the valve and seat, determining the flow of gas; and Fig. 4 is a section plan on the line as m, drawn across Fig. 2.

Similar letters of reference indicate like parts in the several figures of the drawings.

My invention relates to that class of gasregulators used on single burners, and its ob ject is to regulate the tlow of gas; and to that end it consists in the combination, with a receptacle provided with a flexible diaphragm, through which the discharge-tube passes, of an adjustable valve arranged to adapt itself to the valve-seat, irrespective of any irregular movement of the tube, all of which will be more fully understood by the following description and claims.

In the drawing, A represents a sheet-metal case, which is made in two parts, and firmly bolted together at its center, as shown in Figs. 1 and 2. B is a metal tube, which extends upward through the center of the case. This tube is made tight at its lower end, as shown in Fig. 2, and is provided, at a point above the solid portion of the same, with a series of perforations, a. O is a valve, which is loosely attached in the lower end of the tube, and is so arranged as to admit of a slight ratching movement. This valve is adapted to fit a corresponding seat, D, formed in the lower end of a depending tube, (1, attached to the bottom of the case. This tube is screwthreaded externally, by which means it is secured to the gas-pipe by means of the coupling E. F is an elastic diaphragm, which is horizontally attached to the walls of the case at the center of the case, as shown in Fig. 2. This diaphragm is made of leather, or any equivalent elastic material, and is permanently attached to the tube at a point slightly above the perforations a. The elasticity of this diaphragm is such as to admit of a slight ascending and descending movement, by which means the tube is raised and lowered, opened or closed, the valve depending upon the pressure of gas against the diaphragm. G is an annular disk, which is attached to the upper end of the tube, the latter being screwthreaded externally to admit of the same. H is the burner proper, which is attached to the disk over the end of the tube, as shown in Fig. 2. J is a receptacle, which is attached to the tube under the disk. This receptacle is so arranged as to receive auxiliary weights to depress the tube against the pressure of the gas against the diaphragm, by which means the flow of gas is determined. The tube is provided on one side with a V-shaped key, 6, adapted to fit a corresponding groove in the upper end of the case, by which means the tube is prevented from turning when attaching or removing the disk.

In using my invention it is attached to the gas-pipe by the coupling, which allows the gas to flow into the lower chamber of indicated by arrows in Fig. 2. The pressure of gas against the diaphragm elevates the latter, which more or less closes the valve, thereby determining the fiow of the gas.

Having thus described my invention, I claim- 1. In a gas-regulator, the valve 0, made adjustable substantially as shown, in combination with seat D, as specified.

2. The elastic diaphragm F, arranged between the two parts of the case A, in combination with the perforated tube B, provided with the key 6 and adjustable valve 0, as specified.
