ELECTRIC GAS-LIGHTER.

SPECIFICATION forming part of Letters Patent No. 489,653, dated January 10, 1893.

Application filed January 25, 1892. Serial No. 419,164. (No model.)

This two-armed lever is attached readily understood. 70 to a gas-cock of the ordinary form which is Fig. 1. is a full front view of my invention to be tilted back and forth to open and close showing the gas-burner, A, having an ordithe valve.

The reason why a spring is When the gas-cock is closed a simple pull :00 perhaps more essential in my improved form upon the acorn or ball, B, upon the wire, K, is that each extremity and each ball and will cause the arm, 6, of the two armed lever,

E, to open the gas-cock and bring the vertical arm, e, past the fixed electrode so that the flexible contact point E will contact with the same and produce a spark. To turn the gas off, a slight push upon the rod Will raise the horizontal arm, 6', to position against the stress of the retaining spring and tilt thegascock so as to shut olf the gas. The motion of the two-armed lever, E, both in opening and closing, is properly adjusted by means of the stop, 3, to cause the gas-cock to rotate a proper distance only.

I do not claim to be the inventor of what is shown in earlier devices, but

What I do claim as my invention and desire to secure by Letters Patent, is

1. In a hand lighting electric gas burner, the combination of the burner A, fixed electrode Y, two-armed lever E, having avertical arm e, and a horizontal c, and projections 1 and 2, a tilting gas-cock P, rigidly attached to said two-armed lever at about the angle thereof, a wire K, attached to the horizontal arm 6, a contact point upon the vertical arm 6, adapted to make contact With the fixed insu lated arm Y, a leaf spring F mounted upon a block G, and a stop 3, all constructed and combined as and for the purposes set forth.

2. In an electric hand lighting gas burner having a fixed electrode and a two-armed angle or bell-crank lever rigidly attached to the gas-cock and carrying the movable electrode, the combination of a lever-handle for moving said two-armed lever With a leaf spring attached to the burner body, and its free end adapted and normally tending to hold the gas-cock in either an open or in a closed position and to be strained only during the opening or closing of the gas-cock, all substantially as described.
