PRESSURE-REGULATOR.

Specification of Letters Patent.

Patented May 26, 1914.

Application filed August 12, 1913. Serial No. 784,390.

To all whom it may concern:

Be it known that I, JAMES H. REIOHARD, citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Pressure-Regulators, of which the following is a specification.

This invention relates to improvements in fluid pressure regulators, and has for its ob -j ject the provision of a simple device by which the flow of gas or other fluid to' a point of supply may be automatically regulated so as to preserve a uniform pressure at the point of use. v

The invention is illustrated in the accompanying drawing and consistsin certain novel features which will be particularly pointed out in the claims following the hereinafter given detailed description.

In the drawing, I have shown a longitudinal vertical section of a device embodying my present invention.

In carrying out my invention, I employ a casing 1 which is preferably a metallic casting having oppositely disposed nipples 2 and 3 on its sides, the nipple 2 constituting an outlet and being suitably threaded to be engaged by a conductor pipe through.

which the fluid may pass to the burner or other point of consumption. The nipple 3 is preferably externally threaded to be engaged by a collar or coupling 4 having a reduced end 5 to be engaged by the end of the supply pipe leading from the main or other point of supply. By providing this coupling or collar 4, I am enabled to obtain access to the working parts of the regulator without necessitating a complete dismantling of the apparatus, inasmuch as the collar may be rotated so as to be released from the main body or casing 1 without being released from the supply pipe, being merely moved farther thereinto while repairs are being made.

The casing or body 1 is provided internally, immediately adjacent the inlet end, with a depending lug 6 to which is hinged a swinging plate or valve 7. The lower free edge of this valve is adapted to rest against lugs 8 provided at the bottom of the casing so that, even when the valve is in its lowermost position, a passage will be provided to permit flow of the fluid and prevent the cutting off of the supply unexpectedly. The flow of fluid to the point of use will be controlled by a throttle or cut-ofl' valve arranged immediately adjacent such point in the usual manner, as will be readily understood. The valve or plate 7 is equipped on the side facing the inlet with a small lug 9 upon which is hung a small weight 10, and to the said plate or valve is rigidly secured a rod or stem 11 which extends fromthe said plate toward the outlet side of the casing and is bent upwardly so as to extend into an extension 12 on the upper side of the casing, and within the said extension the said stem or rod is again bent to project across the extension, as shown. Upon this-upper portion 13 of the stem is adjustably secured a regulating weight 14 by means of a set-screw 15, and a cap 16 is threaded into the top of the ex tension so as to permit access to the said weight in order to secure the proper adj ustment of the same.

It is thought the operation of the device will be readily understood from the foregoing description, taken in connection with the accompanying drawings. The pressure of the fluid against the valve or hinged plate 7 tends to hold the same against the lugs 8, as shown in full lines in the drawing, while the weight 14 tends to move the valve into the position shown in dotted lines. The weight 14: having been adjusted to permit the valve to close under the normally maximum pressure of the fluid, the burners will be supplied by the fluid flowing under the lower edge of the valve and between the same and the bridge piece 17 from which the lugs 8 project. Should the pressure of the fluid fall, the weight 14: will be free to drop and will, consequently, swing the valve toward the position shown in dotted lines to a greater or less degree corresponding to the decrease in the pressure of the fluid. A greater volume of the fluid will then, of course, be permitted to flow to the burners so that the pressure at the burners will remain uniform. Thesmall weight 10 upon the valve 7, being hung near the free edge thereof, serves to aid the pressure of the fluid in moving the valve toward its seat and tends to prevent the valve moving in a jerky manner so that a fluctuation in the supply at the point of use will be prevented. By using this weight, the valve may be cheaply made of sheet metal but will move as easily and as steadily as a very expensive casting. As the weight is merely hung on the hook 9 it may be removed and a larger or smaller weight substituted therefor and accurate adjustment of the valve consequently effected.

The device is exceedingly simple in the construction and arrangement of its parts and is not apt to get out of order. Should it fail to operate properly after long continued use, the working parts are accessible, so that repairing or cleaning may be easily and quickly accomplished.

' IVhat I cailn is 1. In a fluid pressure regulator, the combination of a casing having an inlet and an outlet, a valve hinged at its upper end with in the casing adjacent the inlet end thereof, a stem secured to the valve and extend ing therefrom within the casing toward the outlet end thereof, and a weight adjust-ably mounted on the said stem.

2. In a fluid pressure regulator, the combination of a casing having an inlet and an outlet, a valve hinged at its upper end within the casing adjacent the inlet end thereof, a weight hung upon the outer side thereof, and a heavier weight adjustably connected to the valve upon the outlet side of the same.

3. In a fluid pressure regulator, the combination of a casing having an inlet and an outlet, a valve hinged at its upper end within the casing to open toward the inlet end thereof, a stop provided within the casing at the bottom thereof to be engaged by the lower end of the valve in the closing movement thereof to prevent complete closing of the valve, and a gravity device secured to the valve and extending therefrom within the casing.

at. A fluid pressure regulator comprising a casing having an inlet and an outlet and an upward extension between the inlet and outlet, a valve hinged at its upper end within the casing to open toward the inlet, a bridge within the casing at the lower side thereof and between the valve and the outlet, stops projecting from the bridge toward the valve, a rod secured to the valve and extending therefrom up into and across the extension of the casing, and a counter-balance adjustably supported on the portion of said rod projecting across said extension.
