sram-rnonucne.

Application filed November 14, 1910. Serial No. 592,375.

abrader 18 is formed directly in the face of the portion 17 while in the construction {shown in Figs. 1 and 2, the a-brader is a and useful Spark-Producer, of which the,

following is a specification.

The object of my invention is to produce a neat and etficient device by means of which a non-electric spark may be produced for the purpose of lighting gas, the structure being designed To receive and operate upon a pyrop'horic substance.

The accompanying drawings illustrate my invention.

Figure 1 is a side elevation of my im- PITOYGCl device; Fig. 2 a similar view in partial section, and Fig. 3 a detail of'a slight modification.

In the drawings, 10 indicates a suitable handle carrying a rod 11, which is provided at its end with anlaxial bore 12 arranged to receive a compression spring 13 and a short cylindrical piece of suitable pyrophoric material 14, such for instance as alloys of cerium. Pivoted at 15 upon rod 11 is a lever 16 provicled at one end with a portion 17 having an abrading member 18 on itsundei' face and overhanging the pyrophoric material 14, the spring 13 serving to drive said material against the abrading surface. Mounted upon the pivot 15 is the eye 19 of a spring 20 the opposite arms of which engage rod ll and lever 16 to normally hold the parts in the position shown in Fig. 1. One end of lever 16 is carried close to handle 10 where it may be readily engaged by the thumb of the operator and the lever of such form that it may be swung to eaus-c' the 40 abrader 18 to traverse its entire length across the exposed end or" the pyrophoric Adj ustably mounted in lever 16 is a temper screw 21 by means of which the normal swing of the lever 16 may be limited, the arrangement being such that, by withdrawing the temper screw sutliciently, thc'abrader 18 may be withdrawn entirely from across the upper end of rod 11 so as to thus expose the end of bore 12and permit withdrawal and insertion of the pyrophoric.

In the construction shown in separate member secured to member 17.

In operation, the instrument is grasped in one hand and lever 16 moved by thumb pressure to the position-shown in Fig. 2. The abrader is preferably of such form that its teeth slide somewhat freely over the pyrophoric during this movement. The lever is then suddenly released, whereupon spring 20 serves to drive the abrtader rapidly across the pyrophoric and remove from it a quantity of small particles which, by reason of the rapid movement of the abrad'er, are

projected forwardly, thus producing an elongated spagk which extends beyond the end of the abrader. By this means, a spark is projected from the implement into the gas to be lighted, thus rendering the operation much more eflicient than is the case in many other implements which have been designed for. use with similarmaterial.

I claim as my invention:

1. A spark producer comprising a handle, a projecting rod carried by the handle and having a bore in its upper end arranged to receive a pyrophoric, a lever pivotally sup ported 0n the rod and carrying an abrader overhanging the end of the rod, :1 spring arranged to drive said lever in one direction,

and means for maintaining the abrader and pyrophoric in contact.

2. A spark producer comprising a handle, a rod projected from said handle and provided with a bore in its end adapted to receive a pyrophoric, a spring mounted in the bottom of said bore in position to receive the pyrophoric, a lever pivoted upon said rod and provided with an abrading member overhanging the end of the rod, and a Specification of Letters Patent. Patented July 18, 19.11.' i

spring engaging the rod and the lever to drive the lever in one direction. I

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana,

this tenth day of November, A. D. one thou sand nine hundred and ten.
