To all whom it may concern:
Be it known that I, JULIUS SCHULKE, of Berlin,l russia, have invented certain new and useful Improvements in Regulators for Oompressed Gas, of which the following is a specitication.
This invention has reference to an improved pressure-regulator for compressed illuminating-gas as used in railway-carriages, steamships, and other vehicles, by which the gas is supplied to the burners in aregular manner and at low pressure, without being affected by the motion of the car or vessel; and the invention consists ofa gas-pressure regulator which is provided with a diaphragm that is connected to the operating-lever mechanism of the regulatingvalve, which mechanism is balanced by. a fulcrumed leverand an adjustablecounter-weight, so as to neutralize the effect of the vibratory motion of the car or vessel upon the valve. The regulating-valve is of spherical shape, its stem being applied to the fulcrumed and springpressed regulating-lever and tightly fitted to its valve-seat.
The invention consists, lastly, of the connection ot' the closed space above the diaphragm by pipe with the hot-air space at the inside of due of the lamps supplied with gas from the pressure-regulator, so as to secure a uniform pressure in the space above the diaphragm and the upper part of the lamp.
111 the accompanying drawings, Figurel represents a top view with parts broken off to show the interior construction of my improved pressure-regulator for compressed illuminat ing-gas; and Figs. 2 and 3 are vertical central sections taken at axial planes, respectively, on the lines as x and y y, Fig. 1, of the same.
Similar letters of reference indicate corresponding parts.
The compressed illuminating-gas which is carried along ,on railway-trains, steamboats, and other vehicles has to pass through a pressure-regulator, so as to be conducted at low pressure to the lamps. The pressure-regulators consist of a cylindrical casing with a metallic or other diaphragm, to thespace at one side of which the gas is supplied through an induction-openin g provided with a regulatingvalve. 1n the closed position of the eductionopening the diaphragm is raised by the pressure of the gas entering from the gas-reservoir, v
and thereby the regulating-valve closed by the action of a spring-pressed-lever mechanism that is connected to the diaphragm and the valve, so that consequently the supply of gas is interrupted. In this position of the regulator there is a certain fixed pressure below the diaphragm, which pressure is determined by the tension ofa regulating-spring. As soon as the eduction-opening of the regulating apparatus is openedthe valve of the supply opening is opened by the lowering of the diaphragm to such extent that as much gas is admitted through the induction-opening as is passed 011' through the eduction opening. Whether a larger or smaller quantity is drawn oft per unit of time, the pressure in the regulator below the diaphragm remains the same,owing to the action of the regulating mechanism. In the gas-regulators as heretofore used this uniformity of pressure could not be kept up, owing to the disturbing influence of the oscillating motion of the cars upon the movable parts of the regulating apparatus. Another objection is that the valves of the regulating devices heretofore used were soon worked out, so as not to tit closely and tightly, owing to the change of position and the weight of the regulating mechanism. To obviate these objections the weight of the regulating-lever mechanism is balanced by means of a lever and counter-weight, and a valve of spherical shape employed, as will appear by reference to the drawings, in which- A represents the cylindrical casing of my improved n'essure-regulator, which is provided with a covering-lid A, that is firmly secured thereto by fastening-screws S. The cylindrical body or casing A of the regulator is provided with an induction-opening, B, that is connected to the supply-pipe leading from the reservoir to the regulator by a screw-coupling, 13, having an interior valve-seat, b. Adiaphragm, O,'of sheetmetal, is arranged at the interior of the casing A, and secured tightly into position to its seat a by a flange or rim,a,of the lid A, and by an intermediate rubber ring or gasket, (o The larger space below the diaphragm 0 forms the regulating- LII chamber through which the illuminating-gas has to pass before being distributed to the lamps.
A disk-shaped plate, d, of sheet metal, is secured to the top of the diaphragm C, so as to stiffen the same and serve for attaching the connecting-rod 0, which extends downward from the center of the diaphragm,it being pivoted at its lower end to the regulating elbowlever D, and above the pivotal connection with the same to a second fulcrumed lever, E, that is provided at the outer end with a counterweight, 9 Fig. 2.
The imluction-opening is closed by a ball valve, F, which fits tightly upon the seat I), the ball-valve being applied to the end of a forked stem, F, which is pivoted to the upwardly-hent end of the elbow-lever I). The elbowlever D is fulcrumed to afixed bracket-arm, g, at the apex of its angle, and acted upon by a spiral spring, I), that is attached at its upper end to the elbow-lever D, and at its low er end by a clamp-screw, h, to a cylindrical extension, h, in the bottom of the casing A. The gas enters the regulator through the induction-opening B of the valve F, and passes out through the eduction-opening to the burners. The course of the gas is indicated by arrows in Fig. 2.
Between theinduction-opening and the ballvalve F is interposed a number of perforated screens, 1), for retaining any coarse impurities carried along bythe gas.
The fixed stem 1 of the regulatingvalve F is pivoted to the shorter arm of the elbow-lever D, and the weight ot'the valve F, valvestem I and clbowdever D balanced by a lever, E, that is fulcrumed to a support, 9, and provided with an adjustable counterweight, g on the lever E that it counterbalances the weight of the regulating-valve F and its lever mechanism, neutralizes the injurious effect of the vibratory motions of the car upon the regulating-valve, and insures consequently the more reliable working of the regulator. Owing to the spherical shape of the valve F and the pivotal connection of its stem with the elbow-lever D, the valve F will always close tightly onto its seat 1) whenever it is pressed thereon, so as to shut ofi' the supply of gas. A more reliably working Valve is thus obtained, which will close the inlet-opening in any position of the regulating-lever, and even after being worn by long use.
A tube, G, is connected to the top of the regulating apparatus and forms the communication between the smaller space above the diaphragm, with the heated air lilling the upper space in one of the lamps supplied by the regulator. This connection of the space of the regulator above the diaphragm with the hotair space of a lamp serves for the purpose of preventing the sudden extinction of the lamps, which is caused by means of strong air-currents, and the difl'erence of pressure which is exerted by them upon the diaphragm and up- The counter-weight is so adjusted on the air supplied to the lamp. In other words, it the connecting-tube G be not used, the lamps arranged in the top of railway-cars and at the head of the locomotiveare exposed to strong air-pressures, which differ frequently from the pressure to which the regulators that are generally arranged below the bottom of the car are exposed. Consequently the lamp and the diaphragm of the regulator are acted upon by air-pressures differing in strength. It is obvious that these differences aifect the regulfir working of the regulator-as, for instance, if the regulator is set for a certain pressure and a greater pressure would be exerted upon the diaphragm the result would be that no gas would be supplied to the burner, and that the light would be extinguished or at least be very irregular. These dilferences in pressure. take place most frequently when the cars enter or leave tunnels, depots, &c., and are the cause of the sudden extinction of the locomotive head-light and car-lan'ips. If, however, in place of the usual air-openings in the top of the regulator, the upper space is connected by the tube (l with a lamp or with the head-light of the locomotive, then the atmospheric air which surrounds the regulator cannot act upon the diaphraghm, but the latter isacted upon by the heated airin the lamp. The tube (1- terminates preferably in the airsupply channel of the lamp, but may also terminate near the same, whereby the air-pressure at the upper part of the lamp would be transmitted by the connecting-tube to the diaphragm of the regulator, and thereby the required unil'ormity of pressure established and a sudden extinction of the lamps prevented.
Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. In an apparatus for regulating the pressure of compressed illuminating gas, a supplypipe, a screw-couplinghavingan interior valveseat, ascreen between the seat and the induc tion opening, and a spherical regulating-valve fixed to a rigid stem and fitted to the valve-- seat, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
