DEVICE FOR INTERIVIITTENT GAS-LIGHTS.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed February 8, 1905. Serial No. 244,770.

To ctlZ whom it may concern:

Be it known that we, CHARLES MATTHEWS, Jr, and ERNEST E. LAUN, citizens of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Intermittent Gas-Lighting Apparatus, of which the following is a full and complete specification, reference being had to the accompanying drawings.

Our invention relates to devices for intermittently supplying gas to a burner wherein the gas supplied to such burner is controlled by a valve that is connected with the moving mechanism of an ordinary meter.

Broadly speaking, apparatus of this general character has been devised; but it is our object to devise by our invention more simple and eflicient mechanism than has heretofore been employed; to provide an improved valve for automatically cutting off the supply of gas to the pipe or pipes carrying it tothe place or places to be lighted; to provide an improved construction for keeping gas always supplied to pilot-lights, from which the main burners are successivelylighted as the valve rotates, and to improve generally the construction and operation of apparatus of this class.

That which we believe to be new will be pointed out in the claims.

In the drawings, Figure 1 is a vertical sec tion. Fig. 2 is a horizontal section through the controlling-valve and its casing, the section being taken at line 1 1 of Fig. 1. Fig. 3 is a horizontal section at line 2 2 of Fig. 1. Fig. 4 is an enlarged detail showing the relative arrangement of one of the gas-burners and its pilot-light.

Referring to the several figures of the drawings, in which corresponding parts are indicated by the same reference-letters, A indicates a gas-meter of ordinary type, the side of the same being partly broken away to illustrate some of the interior mechanism.

B indicates a sleeve arranged vertically in the construction shown and attached to the top of the gas-meter by a plate B preferably formed inte ral with such sleeve, which is bolted or OfilQTWTlSG firmly secured to such At the upper end of the sleeve B is another plate B which, like plate B is preferably formed integral with the said sleeve.

B indicates a vertically-disposed shaft journaled in the sleeve B, to the lower end of which is secured a crank-arm C, suitably connected to another crank-arm C, with which the gas-meter A is equipped, as shown.

E indicates a casing fitting over and tightly secured upon the plate 13, the plate B thus forming the lower wall of a chamber and the casing E the upper and side walls thereof. The chamber thus formed is indicated by E.

F indicates a cylindrical valve connected to the upper end of the vertical shaft B, so as to turn therewith. The under face of this valve F is provided with two relatively large recesses F and F located at opposite sides, as best shown in Fig. 2. The solid portion of the valve between these recesses, as well as the edge portion of the valve, rests upon and fits closely to the upper face of the plate B".

f indicates openings in the valve F, through which gas can pass from the chamber E to said recesses F and F As clearly shown in Fig. 2 and as indicated in dotted lines in Fig. 3, the solid portion of the valve intermediate of the recesses F and F is notched 011 its forward or leading edge, considered with reference to the direction of movement of the valve, so as to form a series of projections f, that are adapted to successively close certain openings 6 in the bottom of the chamber E, through which and through the pipes hereinafter described the gas is conducted to the places where it is to be consumed. The rear edge of the solid portion of the valve is notched or cut away to correspond to the projections on the forward edge, so that the time that each opening in the bottom of the chamber is cut off or obstructed will be the same as any other of the said openings.

It indicates a series of pipes communicating with holes 0 through the plate B which pip es are adapted to conduct gas to the point or points of combustion. In the construction shown these pipes h lead to different compartments of a sign II, where they each terminate in a gas-burner 7. As shown, each of the compartments of the sign H is provided with a letter {1 in its front face, the different letters being separated from each other by opaque division-walls H, so that when a burner in any one compartment is lighted the light from such burner will be confined solely to its own compartment.

G indicates a pipe through which gas that has passed through the gas-meter A is conducted to the chamber E, in which is located the valve F.

G indicates a valve by which the flow of gas so the chamber E can be cut off when de- SlIe I indicates a pipe communicating with the pipe G between the gas-meter and the valve G, through which pipe I gas is conducted to the sign H, the said pipe I being provided with a small opening in each of' the compartments of the same, so that the gas escaping therefrom can be lighted and furnish a very small flame in each compartment, which will serve to light the gas at the burner g, with which each of said compartments is provided, as stated, whenever the gas is allowed to flow through said burner. In Fig. 4 one of such small openings in the pipe I is shown and indicated by 9 These small gas-flames that serve to light the burners on the pipe h are appropriately called pilot -lights. The pipe I is supplied with a valve 7. for cutting off the as therethrough when required.

K in 'cates the pipe through which gas is conducted from the mains or other source of supply to the gas-meter A.

In operation gas will be allowed to flow through. the pipe I, the pilot-lights in the several compartments of the sign II will be lighted, and the chamber E put into communication with the interior of the meter A by opening the valve G in the pipe G. The escape of gas through the pipe I that feeds the'pilot-lights will cause the mechanism of the meter to be set in motion, and through such motion the shaft B will be turned and cause the valve F in the chamber E to revolve. Such revolution will successively bring the projectionsf over the openings 0 in the plate B thus shutting off the supply of gas to the burners in the various compartments of the sign, and by the passing of the solid portion of the valve over these small openings gas will be again admitted to the pipes 72 to be by them conducted to the several compartments of the sign, and by reason of the notching' of the rear edge of this solid portion of the valve, as shown, the gas will be admitted to the various pipes successively, and, as will be understood, as each pipe h is brought into communication with the chamber E the gas emitted from the burner g of that pipe will be lighted at onceby the pilotlight opposite it.

While wev have herein referred to the part A as a gas-meter and While we deem it best touse an actual gas-meterforoperating therotati n valve F, as thereby a single device is use for: the operating means and for recording the amount of gas consumed, it is evident, of course, that it 1s not necessary for the successful operation of our device that the part A be actually equipped with devices for registering the amount of gas that passes through it. The term gas-meter as used herein will therefore be understood to include a device containing mechanism operated by the passage of gas with which our main valve F is connected, whether such part be equipped with registering devices or not.

What we claim as new, and desire to secure by Letters Patent, is
