GAS-CHECK.

SPECIFICATION forming part of Letters Patent No. 792,928, dated- 311118 20., 1905. Application filed September l2. 1903. Serial No. 172,920-

IO particular application to a rotaryv approxi' mately cylindrical check designed to be interposed between a gas meter and a burner for the purpose of regulating the iiow of gas from the meter to the burner.

I 'A further object of my invention is to provide an improved casing having therein a rotary approximately cylindrical valve or plug having a plurality of apertures or oriiices through which gas may pass to the burnerf 2O pipe, said check being rotated to bring a desired number of apertures into line with the burner-pipe to permit the passage of a certain amount of gas therethrough for lighting, cooliing, or heating purposes.

A further object of my invention is to provide an improved check having perforations or gas-openings therein for the passage of gas, the plug breaking or retarding the pressure of the gas passing through the gas-pipe or gasmain.

A further object of the invention is to provide a gas check or economizer which will embody the desirable and essential features of simplicity, durability, and economy.

Vith the above-recited objects and others of a similar nature in view the invention consists in the construction, combination, and arrangement of parts, as illustrated in the accom panying drawings, described in this speciiication, and set forth in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of referencev indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a device embodying my improvements. Fig. 2 is a vertical sectional view taken through the same. Fig. 3 is a perspective view of the rotary gas valve or plug, and Figs. 4 and 5 are modied forms ofv my improved plug-valve.

Referring now to the accompanying drawings in detail, 5 designates the casing of my improvement having a gas-inlet 6 and a gasoutlet 6, the gas-inlet being a short tubular extension designed to be connected, through the medium of a coupling-collar 7, with a pipe 8, leading from a source of gas-supply. The tubular extension 6 is preferably formed integral with the casing and is ared at 9 at the point of communication with said casing, so that as the gas enters from the extension it will be permitted to spread. The casing is preferably of cylindrical form and is designed to have inserted therein a rotary plug or valve 10, (clearly shown in Fig. 3,) said valve having at one of its free end faces 11 a stud l2, designed when the plug is in the casing to pass through a bore 13 in the end of the casing, said stud 12 forming an axis upon which the cylindrical plug or valve may be turned with- 7o in the casing. The opposite flat face 14 of the cylindrical valve-plug is in the nature of' a ange of a greater diameter than the body portion of the plug, said flange being designed to rest against the opposite face of the casing from that having therein the aperture for the passage of the stud 12. This angedface portion of the valve-plug is provided with a groove 15, designed to seat the pivoted liandle 16, said handle being designed to be 8O brought at approximately right angles to the face for the purpose of turning the valve, and when the valve has been so rotated such handle may be folded down into the groove 15, so that the cap or cover 17, which is pivoted at 18 to the side of the casing, may be swung over to conceal the flanged face of the plug. This cover portion 17 is provided with a slotted tongue 19, designed to engage with a lockingpin 20, mounted on the side of the casing to lock the cover against movement when it has been moved to its closed position, the cover being loosely mounted on the pivot 18, so that the slotted tongue may be slipped over and into engagement with the relatively short pin 20. The cylindrical valve-plug 10 is provided to a desired number.

circumferentially, approximately centrally of its curved surface, with series of openings 22, spaced apart, each series being made up of small perforations 23. The perforations of each series differthat is to say, while one has two perforations that of the adjacent series will have three perforations, and so on up On the fianged face of the valve-plug' are numerals, such as shown at 24 in Fig'. l, such numerals indicating the number of small perforations 23 in the series directly in line with such number. For instance, the numeral 2 upon the flanged face in Fig. l, indicates that the series having two perforations therein is presented to the gasoutlet leading to the burner. rlhe curved wall of the plug has also formed therein additional apertures 25, preferably arranged in pairs, each pair being' in line with one of the groups ofl openings 22, the purpose of these apertures being to permit the ready liow of gas from the flared portion 9 of the tubular extension 6 into the valve-plu g, thereby equalizing pressure in the device, gas passing freely through these large apertures into the plug-valve, where it is accumulated and held as a check, so that only the required amount is fed into the supply-pipe through the different series of small perforations.

In Figs. 4c and 5 I have shown slightly-modilied forms of the plug-valve. Vln Fig. al. have connected all the series of apertures 23 with a groove 26, which is formed inthe plugand extends circumferentially thereof, the openings 25 being' arranged in longitudinal alinement with the apertures 23, while in Fig. 5'

the openings 25" are arranged in transverse alinement with the series of apertures 23" and are connected therewith by the circumferential groove 26". The purpose of the groove is to enable the valve to be turned to increase or decrease the supply of gas while the lights are burning without cutting said supply elf entirely and extinguishing the lights.

It will be noted that I have provided a de- Vice which may be readily applied to the existing systems of gas-piping in residences, oflices, and the like and one which will effect a greatsaving in the amount of gas consumed, as it obviates the objection of consuming more gas than is required at the time.

Having thus described my invention, I claim as new and desire to secure by Letters Patentm l. A gas-check, comprising a casing having an inlet and outlet, and a hollow cylindrical lvalve-plug mounted to turn in the casing in contact therewith, said plug being provided with sets of openings arranged at about the center of length of the plugl and adapted to be brought into alinement with the outlet of the casing, and openings of larger diameter than the openings of the sets and adapted to be brought into alinement with the inlet of the casing, the sets of openings being spaced apart and each formed of a plurality of openings, the openings of the several sets varying in number, as set forth.
