UNITED STATES PATENT OFFICE.
CHARLES A. DALLY, OF MOON, PENNSYLVANIA, AND HARRY K. RICHARD SON, OF DETROIT, MICHIGAN. I
GAS REGULATOR AND CUT-OFF.
SPECIFICATION forming part of Letters Patent No. 374,779, dated December 13, 1887.
. Application filed March 14, 1887. Serial N 0. 230.755. (No model.) 7
. The object of our invention is a gas-regula tor arranged to automatically cut off the flow of gas after it has once fallen below a fixed pressure or on a total failure of supply occasioned by accident or otherwise.
The drawing accompanying this specification,and made part thereof, is a cross and longitudinal section of our device.
A is what we choose to call the high-pressure chamber, and Athe low-pressure chamber.
B is a diaphragm. b is'the upper half of the diaphragm-disk, and b the lower half.
b is an air-aperture.
O is a flexible diaphragm, and it is secured to the flange a of the chamber B by bolts in the usual way.
c'isa metallic disk which we use in connection with said diaphragm for support and attachment purposes. I
, D is a lever fixed to the post -D' at d.
d is an adjustable weight on the lever D.
To the lever D is fixed a rod, E, at (1 This rod passes down through the diaphragm-chamber B, and is fixed to the diaphragm itself at e by any suitable means. This lever E goes on down through the part B and into the chamber A, where it is secured to the lever F ate. F is a fulcrum for the lever F. This latternamed lever extends from said fulcrum F, by another arm, f, to the valve-rod F being socured thereto at f. The valve-rod F" is secured to the valve G at the upper end thereof. The valve G is round in form, is closed at the bottom and top, and has several inlet-ports, g, and outlet-ports g, and at the base has a beveled flange, 9 forming, in connection with the walls of the chamber A, a valve-seat.
H is a plug in the opening to the valvebroadly.
seat in the chamber A from above, and H is a plug in the opening to the valveseat and chamber A from below. These openings H and H serve to adjust and regulate the valve .and that is the main object in view in our invention. I I
The required flow of gas by our devlce 1s regulated by means of our system of levers,-
valve, and diaphragm, as aforesaid. When gas is admitted to the chamber A,it passes on up into the chamber B, where it exerts an up- Ward pressure on the diaphragm itself, and by means of the weight 61 such pressure is fixed as required. v
It will be seen that should therebe a failure of gas-pressure on the diaphragm the lever D will descend, thereby pushing down on the valve-lever F, and consequently the valve itself will be drawn upward and closely into its seat, thereby shutting off the flow of gas, and this status will be maintained by the gravity of the weight (2 on the lever D. I
We are aware that it is not new to provide a pressure-regulator with a valve having connection with a diaphragm in a communicating chamber, and that such diaphragms have been connected with a weighted lever, and in some cases the 'dia-phragms have been backed by a spring, whereby the valve may be entirely closed under extraordinary pressure, and we therefore do not claim such constructions,
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
The combination, in a gas regulator and cutoff, of the chambers A and A, having an intermediate beveled valve-seat, the valve G, constructed as described, having entrance and exit ports 9' and g and a beveled flanged In testimony that we claim the foregoing as edge adapted to set against the seat, the lever our invention we hereto set our hands in pres- F, connected to said rod, and the whole arence of two witnesses.
