GAS-REGULATOR.

To all vwhom 'it w1 ay concern Be it known that LCHARLES BAnRINe'roN, Jr.. a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Gas-Regulators, of which the following is a specification.

This invention relates to gas regulators, whereby the How and supply of gas through the service pipes is maintained at the proper rate in accordance with the rate of consumption` so that the pressure may always be kept at a predetermined degree, preventing waste of gas.

The invention relates to certain particular features of construction and organization of such regulators. and has as objects in view the provision of improvements in such regulators which will be superior in point of relative simplicity and inexpensiveness of construction and organization; facility in assemblage and disconnection of parts and,

members, durability, positiveness in action, and responsiveness to variations in working conditions or conditions of use. and which will be generally1 superior in eiciency and serviceability.

`With the above and other objects in View, the invention consists in the novel and useful provision, formation, construction, Vcombination, Iassociation and relative arrangement of'parts, members and features, all as hereinafter described, shown in the drawings, and finally pointed ont in claims.

In the drawing Figure 1 is a vertical transverse sectional view of a gas regulator organized in accordance with the invention, parts being broken away and parts shown in elevation for fullness of illustration; Fig. 2 is a horizontal transverse sectional/view of the same, taken upon the line :r2-?, Fig-1,

and looking in the direction of the appended arrows, parts being. shown in elevation for fullness of illustration; Fig. 3 is a side elevation of the same looking in the direction of the arrow in Fig. 2; and Fig. 4 is a plan View of a detached portion of the showing in Fig. 1.

Corresponding parts in all the figures are designated by the same reference characters.

Referring with particularity to the drawings, the improved gas regulator shown Specification of Letters Patent.

Application led April 4,1913.

therein comprises a casing consisting of a top member A and a bottom member B between which, by suitable screws or bolts 4t or the like, is clamped the edge portion 5 of a flexible diaphragm C, the casing being provided with a lateral extension a within which and beneath the diaphragm C is contined a chamber o communicating with a gas supply pipe o and a gas service pipe d, the former leading to the mains and the latter to the point or points of consumption. A coil spring 6 above the diaphragm opposes yieldingly its upward movement under gaseous pressure in the chamber o, and the diaphragm carries within the chamber Z) a bracket 7 which receives loosely one end of an oscillating arm 8 included within gas feed control means D which operate with respect to a gas port 9 to which leads the gas feed pipe c; the gas service pipe (l and the gas feed pipe c being preferably opposed each to the other at top and bottom of the tubular extension o of the casing and adjacent to the outer end thereof, the gas feed control means D further preferably including a regulating lever 10 and a valve head 11 having compressible facing 12 presented to the inner or upper orifice of the gas port 9. The oscillating arm 8 and regulating lever 1() are jointly supported by and in connection with a closure E for the open outer end of the tubular extension a of the casing, which closurel when in position effeetually stops such open outer end of such tubular extension. The valve head 11 and lever 10 are carried by the oscillating arm 8 and finally by the closure E; and thus. when such closure E is withdrawn it withdraws from the casing with it the oscillating arm 8, the regulating lever 10 and the valve head 11, the gas feed control means, aside from the diaphragm C, t-hus being removed entirely from the casing of the regulator and the feed pipe o and service pipe Z connected with such casing.

The closure E preferably consists of a flat late 13 applied to the flanged outer end 15 of) the'casing extension a and, with an/ interposed gasket 14, being held thereto by bolts or similar securing devices 16. Spaced brackets 17 range inwardly from the plate 13, and a shaft or pin 18 is seated in registering openings in the outer end portions of the brackets 1T and in spaced lugs 19 on the oscillating arm 8 and a lug 2O on the regulating lever 10 which is accommodated between the lugs 19, the latter facing upwardly and the former downwardly. The pin or shaft 18 is disposed slightly inward of the casing with respect to the pipes c and l and the. gas port 9; and the valve head 11 is supported slightly in ward of t-he pin or shaft 18 where one end of a leaf spring Z1 is secured to the oscillating arm 8 beneath the same; the valve head 11 being flexibly carried at the outer end of said leaf spring 21, Aa portion of said valve head passing loosely through an orifice Ql in the spring. A supplementary spring 2G is interposed between the oscillating arm 8 and the leaf spring 21; said supplementary spring 26 being provided with downwardly7 ranging ears 26a l and 2Gb arranged to bear upon the spring 21 at opposite sides of the valve head which has a rounded abutment 27 which engages with the spring Q6.

The regulating lever 10 is provided at its outer end with a downwardly1 directed finger Q2 such finger being disposed above the valve head 11 and acting upon the oscillation of the lever 10 through the spring 2() and the abutment 27 to vary the normal position of the valve head with respect to the gas port orifice, The inner end of the regulating lever 10 carries an adjusting screw Q4 the portion of which beneath such lever 10 bears on the oscillating arm 8. This screw may be manipulated through an openingin the casing extension a at the top of the same, which opening is normally closed by a screw plug Q5. When the finger Q2 of the regulating lever 10 presses against the spring QG in the seating of the valve, the spring 26 is projected into engagement with the abutment 27 forcing the valve head 1() downward and insuring the proper seating of the same.

The operation. method of use and advantages of the improvements in gas regulators constituting the invention will be readily understood from the foregoing description, taken in connection with the accompanying drawings and the following statement c-Gras admitted to the chamber b through the feed pipe c andthe port 9, under control of the gas feed control means D including the oscillating arm 8 and the valve head 11 vieldingly carried thereby and controlled as to its` normal position by the regulating lever 10 which is further controlled by the adjusting screw 24, to which latter a suitable implement may be applied through the opening normally closed by the plug 25. The gas passes from the chamber b into and through the service pipe l to the point or points of consumption. When the pressure becomes too great within the chamber D upon the diaphragm C the diaphragm rises,

rossore raising the inner end of the regulating arm S and depressing the outer end of the regulating lever 10 beyond the shaft 18, and

earrying down Ithe valve head 11 toward or to the orifice of gas port 9, thus shutting oft' in part or in whole the flow of gas from the feed pipe c into the chamber t). When the pressure within the chamber Z) has been diminished by flow of gas outward through the service pipe d, the diaphragm begins to tall, and when the proper pressure is established within the chamber b the valve head l1 will have assumed its proper position with relation to the orifice or gas port 9, which position is maintained until a further tluetuation in pressure takes place. lf the pressure diminishes within the chamber 7;, the diaphragm further falls, permitting the valve head 11 to further move away from the orifice of the gas port 9 until the pres sure within the chamber is restored to the normal, whereupon the diaphragm rises.

The gas feed control means are readily assembled in connection with the other features of the gas regulator by first connecting the regulating lever 10 and the oscillating arm 8 with the brackets 17 of the closure E by means of the pin or shaft 18; whereupon such gas fed control means are introduced within the casing through the open end of the lateral extension a, the extreme end of the oscillating arm 8 finding the open eye 'l'a in the bracket 7, and the valve head 11 coming into position over the orifice of the gas port 9. The plate. 13 of the closure E is then `secured to the outer end of the extension ai, with the gasket 14, and effectively holds the gas feed control means D in working position, in all its parts, and likewise effectively closes the open end of the lateral extension a..

Then it is desired to withdraw the gas feed control means, with respect to the diaphragm C, from the casing and other parts, the securing devices 16 are withdrawn and the plate 13 is removed from the end of the extension a, thereby withdrawing from the rasing the. parts of the gas feed control means D carried by the brackets 1 7, the far end of the oscillating arm 8 readily slipping out of the open eye 'Tuin the bracket on the diaphragm. The pipes c and d are left connected with the casing.

Any repair` substitution or adjustment that may be desired to be made may readily he performed with respect to the parts and features of the gas feed control means, whereupon such gas feed control means may he returned to working positions by slipping the same through the open end of the eXtension a which may then be effectively closed hy applying the plate 1.3 to the end of the extension o and securing it there with its gasket by the securing devices 16.

lt will be seen that the provision of the closure E which in itself acts as a support for the gas feed control means provides for great convenience in assemblage and disconnection of parts and features, enables convenient repair and adjustment and substitution when necessary without entirely taking the gas regulator casing apart or detaching it from the pipes c and d or det-aching any of theparts of the regulator casing from the pipes. The closure 13 .thus constitutes an efficient and detachable support for the gas feed control means D, and likewise provides an efficient and positive closure for the opening in the extension/0f the casing through which the gas feed 'control means lare passed andv withdrawn, in installation or detachment. The valve head ll may readily be adjusted thro-ugh t-he regulating lever l0 and the adjusting screw 24, and is always free to rock and play between the springs 2l and 26, spaced apart bythe ears 26a and 2Gb, so that the valve head shall truly seat under all working conditions.

I do not desire to be understood as limiting myself further than required by a proper interpretation of the fair spirit of the invention irrespective of any particular details other than those specifically claimed.

, Having thus described my invention, I claim and desire to secure by Letters Patent:
