VO LU METRIC GAS-REGULATOR I-EPEGIFICATIQN forming part of Letters Patent No. 352,174, dated November 9, 1886. Application filed April 6, 1886. Serial No. 198,039. (No model.)

T at whom it may concern: Be it known that I, Mosns G. WILDER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new of reference marked thereon, which form a part of this specification.

The object of my invention is to furnish a volumetric gasregulator, which, with slight modifications, may be used to control either an ascending or a descending current of gas, and which will be simple and inexpensive in construction and eflicient in its action.

The accompanying drawing shows a central sectional elevation of my regulator and a yoke for supportingit.

The regulator consists of an outer shell or case, which is constructed of two pieces, A A, an inner shell or case, B, which is united to the outer shell, A, at its center 0, and which is furnished with a hole, D, a disk, E, carrying a valve, F, a flat plate, G, which extends across and is supported within shell B, an adj ustingscrew, H, carried by the outer shell, A, which is adapted to regulate the quantity of gas which passes through opening D in the inner shell, and suitable passages for the passage of the gas to and from the interior of the regulator. The outside shell or case of the regulator is made with plane faces I 1 upon its opposite sides, which are adapted to be clamped or held in the yoke.

J is a hollow thimble, which may be screwed up or down in the yoke, in order to remove or clamp the regulator in place. This thimble is furnished with a recess corresponding to the face I on the regulator.

The regulator shown in the drawing is adapt- .ed for controlling an ascending current of gas,

the course which the gas takes being indicated by the arrows.

The gas passes up into the regulator and into the space J, beneath the disk E, around the annular space K, formed between the two shells A B, through the open ing'D in shell B to the interior of this shell, and from thence throughthe valve-openingL and thimble J to the burners.

The amount of gas which enters case B may be regulated by means of screw H.

An increase of volume of the gas causes disk E to be raised, and valve F, which is carried by this disk, closes the valve-opening L to a corresponding extent, and the regulator continues to deliver the predetermined volume of gas to the burners. A decrease of volume causes the disk and-valve to fall, and allows a greater quantity of gas to pass through valve: opening L. 1

In order to prevent rapid up and down movements (fluttering) of the disk E, I havea flat plate, G, within the shell B. This plate has a hole in its center, sage of gas to the top of this disk.

The regulating-screw H works in athimble, M, which is inserted in the outer shell, A, from theinside, before the inner shell is putin place. This thimble is shrunk, brazed, or otherwise suitably secured to the shell A.

In order to-adapt the regulator to descending currents, some very slight changes are necessary. The outlet N in the upper part of the regulator is closed, as well as the inlets O O in the lower part, and inlets P (indicated by dotted lines) are made in the top of the regulator, corresponding to the inletsOQat present in its bottom, and the post R, which centrally guides and supports the disk and valve, is bored out, as shown by the dotted lines, so as to allow the passage of the gas through it.

Thedirection of the descending currents of gas is indicated by the dotted arrows.

The herein-described regulator may be applied to the main supply-pipe or to a burner, its action in either case being the same.

Having thus described my invention, I claim- 1. A volumetric gas-regulator consisting of an inner and an outer shell, the former being furnished with a hole and the latter with a regulatingscrew, a disk and valve, a plate above said disk and within said inner shell and furnished with a hole at its center, and suitable passages for the inlet and outlet of the gas, the

whole being adapted to govern ascending or descending currents of gas, substantially as set forth.

2. Avolumetrie gas-regulator consisting of an outer shell or case and an inner shell or case having an annular space between them into which the gas freely enters, the said inner shell being united to the said outer shell at its center, a disk and valve centrally guided and supported, and suitable passages for the inlet and outlet of the gas, substantially as set forth.

3. The herein-described device for regulating the amount of gas which enters the inner shell of a gas-regulator and is delivered to the burners, consisting of aholein said innershell and a regulating-screw and its thimble arranged, substantially as described, so that the thimble can be and is inserted into the outer shell from the inside and before the inner shell is put in place, substantially as set forth.

4. The combination of a volumetric or other fluid-regulator made with opposite plane faces upon the shell or case, and a yoke or clamp furnished with similar plane faces and adapted to hold said regulator in place, all substantially as set forth.

5. The combination, with the disk, valve, and case of a gas or fluid regulator, of a fiat plate above said disk extending across and supported in said case, having in it holes of asize s0 regulated that rapid up and down movements of the disk are prevented, substantially as described.

In testimony whereofl affix my signaturein presence of two witnesses.
