LAM PLIG HTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 629,431, dated July 25, 1899. Application filed January 21, 1899. Serial No. 702,944. (No model.)

To all whom-it may concern:

, Be it known that I, FRANK A. CORTlS, of

Meriden, in the county of New Haven and State of Connecticut, have invented certain '5 new and useful Improvements in Lamplighting Devices, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

My invention relates more especially to the class of lamps using gas as an illuminating fluid; and the object of my invention is to provide a device that shall have material advantages as an aid in the operation of lighting a lamp.

To this end my invention consists in the device as a whole, in the combination of parts, and in the details and their combination, as hereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side view of a lamp embodying myimprovement. Fig. 2 is a detail view,-in central vertical section, of the valve, on enlarged scale, looking from the rear of Fig. 1 and with parts in position with the by-pass open. Fig. 3-is a like view, but with the parts in the position with the main fiuidway open and the by-pass closed. Fig. is a detail side view of the valve with the main valve-lever removed and the auxiliary lever in position with the bypass closed, the position of the auxiliary lever with by-pass open being shown in dotted lines. Fig. 5 is a like View with the main valve-lever in place, but broken away, the position of the main valve-lever with the main fluid-way of the valve open being shown in dotted outline. Fig. 6 is a like view showing the parts in position with the main fluid-way of the valve open and the by-pass closed.

My invention-finds a ready application to the class of lamps employing gas as an illuminating fluid and amantle for in creasing the brilliancy of the light, and such a device has been selected herein for the purpose of' disclosing the invention.

In the accompanying drawings the letter a denotes a 'su pply-pipe for supplying gas to the lamp; 1?, the air-shutter, c the gallery,

' and d the mantle, of a lamp of the class above 50 described and of ordinary construction. In

lamps of this class it is desirable to apply flame to the burner before a sufficient quantity of gas has been admittedthereto the explosion of which would result in serious injury to the fragile mantle, and in my improved device I have provided means whereby such a result maybe attained in a ready and effective manner.

A valve-body c is located in operative relation to the burner and is providedwith a valve f, the fluid-way f through which communicates by a passage g direct to the lower part of the burner of the lamp. The valve f has also a by-pass f that leads to a ladder h in a certain position of the valve, in the form shown this result being attained when the valve has been but partially moved in the opening operation of the valve. The ladder h leads from this by-pass to a point'preferably near the base of the mantle (Z,

The spindle 2' of the valve is provided with a main valve-lever Z0 and an auxiliary valvelever Z, the former being rigidly secured to the spindle, but the latter having a limited rotary movement independent of the valvespindle. These levers are supported on a re-' duced portion of the valve-spindle, a pin m projecting from the shoulder formed by this reduced portion into a recess Z in the'edge of the opening in the valve-lever Z, this construction allowing a limited movement of the auxiliary valve-lever independent of the valve-spindle. This auxiliary-lever is employed for the purpose of opening the by-passage only to admit gas to the burner for lighting purposes. This lever is moved to an extent to open said by-passage only and is returned to its closed position in the closing movement of the valve. A recess Z is formed in the outer edge of the auxiliary valve-lever and engages a stope on the valve-body c, this stop limiting the rotary movement of the lever Z.

The main valve-lever has a recess 70 in its outer edge, that also engages the stop 6 to limit the rotary movement of the lever, this stop by engagement with the recesses in each of the levers, as described, controlling the movement of the valve and determining its open and closed positions, and also the po- IOO sition of the valve in its intermediate position to communicate with the passage through the ladder h. The outer end of the main valvelever extends beyond the outer end of the auxiliary valve-lever, so that the former may be moved independent of the latter.

The operation of the device is as follows: The several parts being in the position shown in Fig. l of the drawings, the auxiliary valvelever Z is moved upward until the end wall of the recess 1 encounters the stop 8. The parts are then in the position shown in Fig. 2, with the by-pass admitting fluid to the ladder h. The main valve-lever is now moved upward, carrying with it the valvef, the pin m on which moves aroundin the recess Z in the auxiliary valve-leverl to the position shown in Fig. 6, the main fluid-way through the valve being open and the by-pass closed, as shown in Fig. 3 of the drawings. The parts being in the position shown in Fig. 2, flame is applied to the lower part of the ladder and travels along the same to the base of the mantle. The parts being now moved from this position to that shown in Fig. 3, fluid is admitted through the main fluid-way to the burner, but before the flame on the ladderhas been extinguished and which serves to light the lamp, this being accomplished before a sufficient quantity of fluid has been admitted to the burner the explosion of which would seriously injure'the mantle.

It is to be understood that my invention is not limited to the precise means of accom plishing this result as herein shown and described, any means involving the use of a lever pivoted on the valve to rotate the same, but having independent rotary movement thereof for the purpose of admitting fluid to the burner through a separate passage and before the main fluid-way of the valve is fully opened, coming within the scope of my invention.
