FLUID-PRESSURE REGULATGR.
This invention is a device for regulating the flow of a fluid by the variations in the pressure thereof, and` more especially 1t 1s intended-for attachment to a gaseous fuel supply system and for adjustment so that as the pressure of the gas increases the valve or valves will close more or less according as the device is set.
The objects of this invention are to improve regulators of this type hitherto constructed, to which end the invention consists in the details of construction hereinafter more fully described and claimed and shown in the drawings wherein- Figure 1 is a side elevation; Fig. 2 is a plan view; Fig. 3 is a central vertical section; and Fig. 4 is a section on the line 4-4 of Fig. 3.
In the drawings the numeral 1 designates a base having a flange 2 around its top and a closed and slightly dished bottoln 3 pierced with an inlet opening 4 through which the pressure of air, vapor, gas, or fluid is admitted. Thenumeral 5 designates a frame comprising a series of uprights connected by a bottom flange 6 which is bolted to said flange 2 as shown, a top plate 7, and a central cross bar S, the whole being of open or skeleton construction and its sides preferably provided with upright slots 9 as shown.
Between the flanges 2 and 6 is bolted the edge of a diaphragm 10 which is of any suitable flexible material and which, with the fixed bottom 3, forms a pressure chamber in a manner to be described below.
Resting upon the center of the diaphragm 10 is a cup 11 of a size to receive the lower end of an expansion coil spring 12 whose upper end passes into a head block 13 which is carried by the cross bar 8 and is capable of being adjusted by means 0f a bushing 14 which screws into said head block in a manner which will be clear. Hence the adjustment of this bushing with- Specicaton of Letters Patent.

in said block adjusts the tension of the `main spring 12 whose function is to cause the descent of the cup 11 in opposition to the expansive force of the pressure agent admitted at 4.
Resting upon the center of the cup 11 is an' upright stem 20 which rises loosely throughout the spring 12, head block 13, bushing 14, and upward through the frame, its upper end being guided in the top plate 7 thereof through a bushing or other suitable guide 21. At a suitable point within its length this stem is threaded as at 22, and screwed thereon are nuts 23 above and below a movable guide bar 24 which extends across the frame and whose extremities are projected through the slots 9 therein.
From the construction thus far described, when the pressure causes the diaphragm and its cup to rise and com resses the spring 12, the stem 20 will also e elevated and with it the guide bar 24 will be raised within its guide slots 9.
While it is possible to use this improved regulator in connection with a single valve or with a number of valves, I have shown it as connected with two. The casing of each is designated by the numeral 30, and the valve stem 31 extends downward from the casing through a gland 32 seated in the top plate 7 of the frame, its lower end 33 being threaded and passing through the guide bar 24 where it receives nuts 34 above and below the latter, and by means of which the exact position of the valve stem and hence of the valve head with relation to the guide bar can be adjusted at will.
The numeral 35 designates a light expansive spring coiled around the valve stem 31 between the gland 32 and the uppermost nut 34, and the force of this spring tends to move the valve stem downward and open the valve.
The parts are of the desired sizes and proportions, and as yabove suggested any number of valves may be connected with the cross bar 24 and each controlled individually by its own spring 35. When the pressure increases the diaphragm will raise the cup 11 and compress the main spring 12, and the cu 11 will also raise the stem 20 and the guide bar 24 and compress all the valve springs 35. The rise of said bar will also lift the various valve stems 31 whereby their respective valves will be closed more or less according as said 'stems are set within the guide bar by means of the nuts 34. Thus it will be seen that a number of Valves may be controlled by the movement of this sin# gle guide, but each is susceptible of its own adjustment. It will also be clear that where the pressure is normally quite highthe bush- `ing 14; can be adjusted within the head block 13 to put more tension on the main stem 12 and thus prevent the cup l1 from rising until the-pressure increases beyond its normal high level.
What is yclaimedas new is: l. In a liquid or vapor fuel burner pressure regulator7 the combination with a framework having guides, a diaphragm- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
project through said guide bar7 nuts 'on the stems above and below this bar, and a spring acting on the Abar to hold the valves normally open.
2. In a liquid or vapor fuel burner pressure regulator, the combination with a framework having guides in its sides and one in its top, a cross bar whose extremities move in the former, an upright stem passing through said bar and with its upper end moving in the last-named guide, pressureactuated means for raising said stem, and a main spring counteracting the force of said lift-ing means; of a series of valves whose stems are connected with said guide bar, means for independently adjusting their points of connection, and means for adjusting the point of attachment of said bar upon said stem.
In testimony whereof I have hereunto set my hand in presence oftwo subscribing witnesses. l
