GAS-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 260,039, dated June 27, 1882.

To all whom it may concern:

Beit known thatI,Lnw1s H. MoCULLoUGH, a citizen ofthe United States, residing at Richmond, in the county of Wayne and State ofIndiana, have invented certain new and useful Improvements in Gas-Regulators, of which the following is aspecitication,reference being had therein to the accompanying drawings.

My invention relates to magneto-electrical gas-regulators for controlling the flow of gas to gasburners placed in street or oth er lam ps and4 suitably connected to a battery, in order that the tlow of gas to a single burner, or to a series of burners at one point, or to a series of burners placed in a particular district or upon a single circuit, may be regulated, it being designed as an improvement upon the device for which an application for Letters Patent was tiledby me in the United States Patent Office on the 31st day of December, 1881; and the objects ofmy present improvements are, first, to provide such a construction and combination of devices as to enable me to dispense with the case and its contained insulating material shown in said pending application second, to provide a method of preventing the armature from adhering or sticking to the core of the magnet; third, to provide an armature so constructed and arranged that it shall be moved into its proper position for shutting the gas from the burner by the magnet, and in the opposite direction so as to allow the full amount of gas to flow to the burner by its own gravity; fourth, to provide such devices and combinations thereof as will produce the results herein described. I attain these objects by the devices and combinations thereotl illustrated in the accompanying drawings, in which- Figure l is a plan or top view, showing the gas-burner, the bar to which itis attached, the magnets, the binding-posts, the connectingwires, and the gas-chamber. Fig. 2 is a vertical section on line :v of Fig. l, showing the gas-induction passage, the gas-chamber, and the armature located therein, a valve forming a part of said armature, a thin sheet of brass or other non-m agnetizable metal, and pipes for conducting the gas from the chamber to the burner, the magnets, the connecting-Wires, and the burner. Fig. 3 is a sectional elevation on line y y of Fig. l and Fig. et is a perspective view ofthe armature, showing its pivotal point and the location thereon ofthe gas-controlling valve.

Similar letters referto similar parts throughout the several views.

In constructing regulators of this type it is important that they should be as light as possible, and that they should be reduced to the smallest practicable dimensions, in order that they may be readily and safely attached to the pipeleading thereto. With this object in view I provide a socket,A,which has a screw-thread upon its inner surface for attaching the regulator to the induction-pipe, said socket being formed upon or attached to a plate of metal, A,which forms the under side ofthe gas-chainber B, the side walls of which are composed of a frame, B', of brass or other suitable metal, it being of such length as to adapt it for the reception and support of a thin sheet of brass or other Vnon magnetizable metal, B2, upon which the lower ends ofthe cores of magnets C and C' rest, said thin sheet being the upper surface of the gas-chamber B, within which there is pivoted an armature, D, the pivotal point of which is at or near one of its ends, in such a manner that when drawn upward the valve D' upon its upper surface may rest upon the lower end ofthe pipe E,which conducts the gas from chamber B to the burner, and thus close or nearly close the end of said pipe, at which time the upper surface ofthe armature will bein contact with the thin plate B2, in which position it will be held by the magnetism which passes through said plate from the cores of the magnets so long as the current of electricity is maintained through the wires leading to the battery; but when such current is broken or ceases to pass the gravity of the armature will cause its free end to fall down suihcieutly far to remove the valve from the end ofthe pipe, which will allow gas to flow to the burner, the armature being prevented from falling too low by any suitable stop provided for that purpose, or by coming in contact with the lower plate of the gas-chamber.

In order that a small flame may be constantly maintained at the burner, the material of which the valve D is made is, by preference, ofsome porous substance-such as buckskin or other soft leather--which will allow gas enough to IOO pass it for that purpose; but said valve may be made of some soft metal, and have in it a small crease or groove for the passage of the required amount of gas, it being desirable to have only so much pass as will serve to ignite the larger quantity when it is turned on by the opening of the valve. f

The magnets C C are of the usual or any ap proved form, and have central cores, F, made of soft iron, the lower ends of which, as above stated, rest upon the thin plate B2.

Upon the sides ofthe frameD there are formed projecting ears G G, in which are secured the binding-posts G G2, to which the circuit-wires are attached, the current from the battery entering at G and passing through a wire, H, to one of the spools or helices ofthe magnet, and from that to the other, as shown infFig. 2, and out through the wire H to post G2, and from thencethroughawire attachedthereto, through which it passes to another burner, and so on to other burners that are placed in the line or circuit. v v

The gas-burner I is provided with a hood, I', which may be of the form usually employed on coal-oil lamps, or of any other that willpreveut the small iiame from being extinguished by the wind. The armature is shown as being provided at its pivoted end with a rod which pro- 3o jects therefrom upon both ofits edges, the intention being to have said projecting ends pass through the side bars of the frame D; .but as it is important that the armature shall be so suspended as to allow it to bel moved with the least possible amountof friction I prefer to suspend it upon screws or pins passing through said frame, having pointed ends, which shall entercorresponding cavities formed in the sides thereof.

For conveniencein removing the burner from its lower plate, it is attached thereto by screws, as shown in Fig. 2, so that, should the armature or its valve need adj ustmentat any time, it can be done without unscrewing the bottom plate from the pipe. For the purpose of protecting the wires ofthe magnet from the effects ofthe elements, I prefer to first dip themin wax,paraf fine, or other similar non-conductin gsubstance, and afterward cover them with hard rubber.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

4thin brass or other non-magnetizablc metal, an

armature which, when the circuit is closed, rests uponthe under surface of said thin plate, and a magnet or, magnets the core of which rests upon its upper surface, substantially as andfor the purpose set forth.

3. The combination of the gas-chamber B, one of the walls of which is ot' thin brass or other non-inagnetizable metal, the armature D, valve D', secured upon and moved by said armature, the gas-conductingpipepassingup between the magnets and through the heel-piece, and the burner I, the parts being arranged substantially as shown.

In testimony whereof I atiix my signatureiu presence of two witnesses.
