GAS-CHECK.
SPECIFICATION forming part of Letters Patent No. 415,804., dated November 26, 1889.
Application iiled August 22, 1889. Serial No. 321,650. (No model.)
T0 all 1073017@ it may concern:
Be it known that I, THOMAS ANGELL, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Pressure-Regulators, of which the following is a specification.
The object of this invention yis to simplify the construction and lessen the cost of the gas-check, and to provide for easily adapting the parts to the different conditions of pressure in gasm ains.
In the drawings, Figure I is a vertical section of the improved gas-check, and Fig. 2 is a sectional plan at the line a' fr.
The gas passes to the regulator or check by the pipe a, and at Z) a portion of the pipe leading to the gas-fixtures in the building is represented. The body c of the check extends out laterally from the cylindrical portion c', and at d is a supply-tube coupling forming a connection from the pipe d to the cylinder c and having at its upper end a seat for the valve f, which seat is preferably conical and the lower end of the valve of a similar shape, and there are guide-fingers 3 3 extendingtdown from the valve and within the coupling-tube d to keep the valve in position, but allow of its free vertical movement.
The body c receives the vertical stand-pipe e, that is screwed into the body c, and such stand-pipe passes centrally through the bottom of the holder 7L for mercury or other liquid, and the parts are made tight by a lock-nut 4 or similar device with packing of red lead or other material. Through the stand-pipe e there is a freely-moving stem C, fastened at its upper end to the inverted cup la, that is within the holder h, and the lower end of this cup passes into the mercury or liquid within the holder. The lower end of the stein g is mortised for the passage of the lever Z, that at its other end passes into a slot in the weighted valve f and below the crossbar or pivot 6, and there is a fulcrum-pin o', that passes across the body c and through the lever l.
There is a removable screw-cap n atthe end of the body c for introducing or removing the lever Z, and I remark that thc lever l, being nearly straight and plain, is easily passed through the mort-isc in the lower end of the stem g and into the slotted valve, and the fulcrum-pin i can be placed wherever desired, so as to vary the relative leverage of the weighted valve and the inverted cup.
It is to be understood that the weighted valve f is sufficient to close the inlet-pipe a d, but it is counterpoised by the stem g and inverted cup so as nearly to balance, and when the pressure ot' gas below the valve acts to lift such valve the inverted cup 7c descends, and the gas-pressure acting inside the inverted cup tends to raise the same and thereby lower the valve, and according to the pressure of gas required on the house side of check so the relative weight and leverage ot the inverted cup and valve may be increased or lessened, and for this purpose weights may be applied at o, Fig. I, to load the cup, or countersunk holes may be bored in the top of the valve f to lessen its weight, and by removing the screw-plug and the fulci'um-pin t the lever l can be drawn out for repairs or for changing the leverage between the valve and inverted cup by boring another hole and plugging up the iirst hole.
It will be apparent that, in consequence of the valve being slotted and having a crossbar, the inverted cup can rise Vor fall to a limited extent without moving the valve, thus allowing for slight changes of pressure, and the valve is free to rest by its own weight on the seat, and the regulator is cheap and easily constructed and kept in repair.
I am aware that the valve has been hinged to one end of the lever and the stem of the cup hinged to the other end of the lever, and that a lever has been used` that is not hinged to the valve.
By my improvement both the valve and the stem of the cup are free to accommodate themselves to their proper position, because there is not any hinge at either end of the lever, and this renders the apparatus cheaper ICO pipe screwed to the body, the holder for :L 'cap at the end of the body, substantially as liquid,4the inverted cup, the stem passing speoiiied. 10 through the stand-pipe and to the upper end Signed by nie this 20th dayof August, 1889.
