BEN F. KEITH, OF BELTON, TEXAS, ASSIGNOR OF ONE-THIRD TO THOMAS S. LOVETTE, OF BELTON, TEXAS.

AUTOMATIC GAS-LIGHTER.

To all whom it may concern:

Be it known that I, BEN F. KEITH, a citizen of the United States, residing at Belton, in the county of Bell and State of Texas, have invented certain new and useful Improvements in Automatic Gas-Lighters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to automatic gas lighters, designed more particularly for igniting the headlights of an auto vehicle, and one of the principal objects of the invention is to provide a simple automatic igniter which can be readily attached to any automobile, and which will be inexpensive to manufacture, which will be economical to maintain, and which will be reliable and efficient for its purpose.

The foregoing and other objects and advantages may be attained by means of the construction illustrated in the accompanying drawings, in which- Figure 1 is a diagrammatic view showing the pipe connections to the burners, the gas tank, the electrical connections, and the automatic igniter, Fig. 2 is a side elevation of one form of gas lighter made in accordance with this invention, Fig. 3 is a top plan view of the same, Fig. 4 is a side elevation of a modified form of clamping device for holding the igniter to the burner tube, Fig. 5 is a top plan view of the same, Fig. 6 is a side elevation, and partial section of an igniter having a clamp or holding device of modified form, Fig. 7 is a view in elevation taken at right angles to Fig. 6, Fig. 8 is a sectional view taken on the line 88 of Fig. 6, Fig. 9 is a sectional view taken on the line 99 of Fig. 7, and Fig. 10 is a side elevation taken at right angles to Fig. 4.

Referring to Fig. 1 of the drawing, the numeral 1 designates a gas tank of suitable size and capacity, and 2 are the pipes leading from the tank to the burners 3 to be used in the headlights of an automobile. The pipe 2 is provided with a branch 4 and a suitable valve 5 is disposed in reach of the driver at the dashboard 6. A press button 7 con nected up by the conductors a and b to the battery and to the igniter, designated as an entirety by the letter 03. When it is desired to light up the lamps of the automobile, the

valve is turned to admit gas to the burners, and the button 7 is then pressed to operate the igniters.

lVhile this invention is especially adapted for use on automobiles, it will be obvious that the automatic gas lighter may be used for many other purposes. Referring to Figs. 2 and 3 of the drawing, the numeral 8 designates the gas burner, and 9 are jet tubes which are arranged to diverge from the tube 8, and are each provided with a jet opening near the outer end thereof. Clamped to the burner tube 8 just below the jet branches 9 are the porcelain insulator members 11, which are firmly connected to the tube 8 by bolts or binding posts 12 which extend through the insu lators 11 and are provided with nuts 13 for holding the conductors a and b in connection therewith. At the opposite ends of the binding posts 12, a short length of platinum wire 14 twisted together is secured to the binding posts and held in position by means of the heads of the bolts, said platinum wire or other suitable incandescent conductor is passed over the jet opening 10 or at a position slightly to one side of said jet opening. The incandescent conductor 14 may be held in position adjacent to the jet opening 10 by grooves 14. however, extend through the branch tubes 9 in a position at one side or in line with the jet opening 10, thus being removed from the flame of the gas jet but being in suflicient proximity thereto to ignite the gas.

Referring now to Figs. 4, 5 and 10, a rubber insulator 11 is provided having a central opening 15 for the burner tube 8, and two oppositely disposed apertures 16 for the binding posts 17. Binding screws 18 extend through the lower ends of the posts 17 and bear against the terminals of the conductors a and Z), while at their upper ends binding screws 19 are utilized for securing the platinum wire 14 or other suitable incandescent conductor to the binding posts 17. It will be understood that the binding posts are insulated by therubber element 11.

Referring to Figs. 6, 7, 8 and 9, of the drawings, a metal clamp 20 is secured to the burner tube 8 by means of a binding screw 21, and secured at opposite sides of the clamp 20 are supporting rings 22. Mounted in the rings 22 are metal tubes 23 having an insulating core 24. The core 24 The platinum wire may,

is provided with a hole or socket for the platinum wire l l which is held in place by means of a binding screw 25. The conductors a and b are connected to the core 2% by means of the binding screw 26.

From the foregoing it will be obvious that various forms of clamps may be utilized, and that the automatic gas lighter may be used for many purposes.

Various changes may be made in the details of construction without departing from the spirit and scope of the invention as de fined in the claims.

\Vhat is claimed is 1. In a gas igniter, the combination with a burner having upwardly diverging jet tubes provided with jet openings, one of the tubes having an exterior groove in its upper inclined side or face, said groove being located adjacent to the jet opening of such tube, an insulator mounted on the burner below the said tube, an incandescent resistance wire extending over the grooved Copies of this patent may be obtained tube of the burner and arranged in the groove thereof, the terminals of the resistance wire being secured to the insulator and conductors also mounted on the insulator and connected with the terminals of the resistance wire.

2. In a gas igniter, the combination with a burner, of a sectional clamp of insulating material engaging the burner, binding posts located at opposite sides of the burner and connecting the sections of the insulator or clamp, a resistance wire extending over the burner and connected at its ends to the terminals of the binding posts at one side of the clamp and conductors connected to the other terminals of the binding posts and located at the opposite side of the clamp.

In testimony whereof I afiix my signature in presence of two witnesses.
