Gas Regulator.

Patented June 12, 1869.

Specification of Letters Patent No. 28,722, dated June 12, 1860.

To all whom it may concern:

Be it known that I, SAMUEL H. IVHITA- KER, of Cincinnati, Hamilton county, Ohio, have invented a certain new and useful Improvement in Gas-Regulators; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification.

The subject of my invention is an apparatus consisting of a metallic case containing a receiving and a discharging chamber, both closed from the external air, and separated by a flexible and impervious diaphragm adapted to open and close a communication between the said chambers by the unequal pressures of the entering and escaping gas upon its respective sides, and the invent-ion futher consists, in connection with the above, in an arrangement of devices for adjusting the capacity of the apparatus.

In the accompanying drawings, Figure 1 is a perspective view of a regulator embodying my improvements, with the upper casing removed. Fig. 2, is a vertical section of the apparatus complete.

A and B represent respectively the lower and upper chambers of a metallic vessel of spheroidal or other suitable form secured together by screw bolts at holes C, and holding between them the periphery of an annular diaphragm D of saturated leather or other suitable impervious and ductile material.

E is a metallic valve secured to the center of the diaphragm D and supported, when at rest, upon a seat F connected adjustably to the top of the vessel A, B, by means of a rod G and nut H.

a and Z) are respectively the ingress and egress ports.

e are apertures permitting the passage of gas through the valve E when in its elevated position.

The operation is as follows: Gas enters at a, and raising the valve E from its seat, by pressure beneath the diaphragm D, passes through the ports 6, into the chamber B, and through the exit I) to the burners. IVhile the pressure of gas bears a due relation to the discharging capacity of the burners, the

constant flow through the apparatus results in a pressure in the chamber B, equal to that in the chamber A, less the vweight of the valve and diaphragm but any excess of pressure beyond the capacity of the burners tends to overcharge the part above the diaphragm, so as to equalize the pressures in the chambers B and A and thus allow the valve E to partially close by its gravity and obstruct the fiowand the same effect is produced by closing one or more of the burners. The reverse of these actions of course takes place either by opening a greater number of burners or by a decrease of pressure in the main. In the former case the partial removal of pressure from the upper side of the diaphragm, naturally allows it to be elevated by the excess of pressure beneath, and in the latter case the greater capacity of the burners, relatively to the pressure from the main produces a like result by preventing the continuance or accumulation of excessive pressure in the upper chamber.

A leading feature of utility in the above described regulator, is the security afforded against the escape of gas, in the event of the internal parts getting out of repair, neither side of the diaphragm being exposed to the external air.

A spring may be applied to operate either in combination with or instead of the power of gravity in drawing the valve to its. seat. By this means the apparatus may, it referred, be made to operate with equal e ect in other positions than the one exhibited. The diaphragm may thus have a vertical instead of a horizontal position or the receiving chamber A, may be above, and the discharge chamber B, beneath. The ingress and egress pipes communicating with the main and burners respectively may form together an inverted siphon with the regulator at the apex, in which case the said pipes will be made to communicate with the extreme lower part of each chamber. The stem G may be in the form of a thumb screw working in a fixed nut.

I claim as new and of my invention herein and desire to secure by Letters Patent 1. In the described connection with receiving and discharging chambers A and B the purpose of adjusting the capacity of the apparatus from the exterior. 10

In testimony of which invention, I hereunto set my hand.
