LIGHTING ATTACHMENT FOR GAS-STOVES.

SPECIFIGATION forming part of Letters Patent N 0. 741,991, dated October 20, 1903. Application filed February 3, 1903. Serial 1T0. 141.673- (No model.)

To aZZ whom it may concern.-

Be it known that I, LESLIE E. ADAMS, a citizen of the United States, and a resident of Galena, in the county of'Delaware and State of Ohio, have made certain new and useful Improvements in Lighting Attachments for Gas-Stoves, of which the following is a specification.

This invention relates to lighting-attachments'for gasstoves; and itconsists of a new and improved attachment of that character having a pilot-light adapted to be kept burning with gas stored under pressure in a suitable holder or tank.

It is well known that the pressure of gas varies in the mains and that at times is so low as not to furnish sufficient gas to keep a lighted stove burning. At times it becomes necessary to leave the room or house for a short period of time, in which there isa lighted gas-stove. During this period the pressure of gas in the mains may fluctuate and get so low as to allow the jets to flicker outor be blownoutbyslightdraftofair. Myinvention is designed for relighting the jets upon return flow of gas to normal pressure in the mains, and I effect the relighting by peculiar means which I will describe as follows with reference to the accompanying drawing, forming a part of this specification, and in which is shown a front elevation of my invention in use.

While my improved attachment is adapted for lighting any type of gas-stove, in the drawing I show it in connection with an ordinary heating-stove A. The pipe B shown is the usual gas-supply pipe which ordinarily enters the stove with a horizontal portion 0, having a cut-off D at the stove end thereofl Eindicatesa suitable holder into which gas is forced, as will be described further on.

F indicates a small tube,having in its length a regulating-valve G. The tube F is intended for conveying gas from the tank E to the pilot-light H, as shown. In connection with the tank E, I employ a pressure-gage I, the use of which will be understood. In my drawing I show the tank E secured to the pipe 0 by two clamps J; but obviously any other means may be employed therefor which is adapted to the purpose.

K indicates an ordinary air-forcing pump,

shown resting on the floor. Near the lower end of this pump I provide inlet and outlet nipples L M,having check-valves O P, the latter checkvalve P being adapted to be seated by pressure of air in the pump-cylinderon the downstroke of its piston, and the former O is adapted to be opened by the same pressure. In other words, as will be understood from the following description, upon upward stroke of the pump piston suction produced in the pump-cylinder will unseat the valve P and draw in gas through the nipple M. Downward stroke of the pump-piston puts the gas in the pump-cylinder under pressure adapted to seat the valve B and open the valve 0. The nipple L and a suitable nipple Q on the tank E are connected, preferably, by flexible tubing R. The nipple Q should have a cut-0E valve S, as shown. At any suitable location on the pipes B or C, I provide a nipple T, having a cut-off valve U, and I connect the latter nipple 'l with the nipple M on the pump preferably by flexible tubing V.

In describing the use of my invention it becomes necessary only to say that shoulda person desire to leave a lighted gas-stove for a short time the valves S and U'are opened and the pump worked, as will be understood. Upon upward stroke of the pump-piston gas is drawn in the pump-cylinder through the tube V, and upon downward stroke of the pump-piston the pressure of gas produced thereby in the pump-cylinder lifts the valve 0 at the pump end of the tube It and gas is forced through the said tube E into the tank E. The pump should be worked until sufficient gas is stored in the tank E adapted for keeping the pilot-light burning while the person is absent from the room. Now obviously with my improved lighting attachment a person can fill the tank to the desired pressure and with the pilot-light lighted leave the gas-stove burning and feel assured that should the jets go out, owing to insufficient supply of gas or from other causes, upon renewed pressure or supply of gas the jets of the stove will be regulated by the pilot-light.

Having thus described my invention, what I claim as new, and desire to secure by Letter Patent, is

1. An improved lighting attachment for gas-stoves, employing a tank, a pilot-light as too specified, tubing connecting the said tank said nipples, the tank and the gas-supply main, and valves at the feed and supply ends of the said tubing, adapted one to close the inlet into the tank, and the other for cutting 15 off the supply at the gas-main substantially as described.
