Specification of Letters Patent.

Application filed August 17, 1909. Seriai No. 513,269.

Patented @ct.22,1l912.

To all whom it may concern:

Be it known that I, CONRAD HUBnn'r, a citizen of the United States of America, residing at borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Lighters, of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

My .lIlVGIltlOIl relates to ignition devices of that type employing frictional sparking devices and relates more particularly to gas lighters. 7

My invent-ion is adapted to employ a sparkin material known as a pyrophoric alloy, w ich when subjected to friction by a hard metallic substance, such as steel, will freely produce sparks capable of effecting ignition. Such pyrophoric alloys are now known to .the art and may constitute an alloy of someone or more of the rare earth metals, for example, an alloy containing cerium and iron has been found suitable for the purpose. However, it should be understood that my present invention is not directly concerned with the nature or compo-.

sition of the pyrophoric alloy employed, but has to do with anignition device adapted to employ such sparking material or pyrophoric alloy. r

Myinvention has for its objects sim plicity of construction, inexpensiveness of manufacture, durability. and efiiciency, and comprises several features of construction. including two, slides arranged to reciprocate at an angle one to the other and connected together for concurrent movement, movement being-imparted to one of the slides and the frictional sparking. devices being ,actuatec by theother of the slides.

My invention also includes a friction member pivoted on one of the slides and pressed into, frictional sparking engagement with the sparking element by a spring mounted on the guide for the slide.

My invention also includes an automatic trigger mechanism operating to retract and release the sparking device while the trigger is being pressed. w

My invention also includes several details of construction and combinations of parts, as will hereinafter appear.

I shall now describe my invention with:

reference to the accompanying drawings and shall thereafter point out my invention in claims.

Figure l is an elevation of the complete dev ce on a reduced scale. Fig. 2 is a partial central vertical section, with a part of the longitudinal tube broken away. Fig. 3 is a longitudinal section of the u per part of the igniting arm on a. plane in icated by the line 33 ofFig. 2. Fig. 4 is an elevation of a portion of the upper part of the device as viewed from one side of Fig. 2. Fig. 5 is an enlarged transverse section on a plane indicated by the line 5-5 of Fig. 2, looking upward. Fig. 6 is a detail in perspective of the trigger spring. r

In the embodiment of my invention illustrated in the drawings, two guide tubes 11 and 12 are joined together at an oblique angle by a connecting piece 13. The tube 12 is considerably longer than the tube 11 and at its lower free end carries a handle 14. .The sparking devices are loc'ated at the upper free end of. the shortertubell. which forms the igniting arm of the device. The connecting piece 13 is prolonged in alinement with the longer tube 12 to form a shank 15 terminating in a gas cook turner 16 of usual construction, as shown in the drawings. The sparking devices carried at the upper free end of the shorter tube 11 a slide 19, which is vertically slotted at its:

outer end and carries pivoted in the .slot a pawl-like arm 20 on a pivot pin 21. The arm 20 is provided with teeth forming a roughened surface at its outer, free-end on the lower side adapted to frictionally engage. the sparking element 17 when the slide Within the 19 is moved in the .guide tube 11. The teeth of the friction element 20 are inclined outwardly toward the free end of such element so as to more firmly engage the sparking element 17 by-the outward movement of such friction element and to offer a minimum of friction to the retraction of the friction eleinent. This effect is enhanced by retracting the slide 19 with a comparatively slow movement and advancing it by pushing it outward by a comparatively quick move ment to produce sparking. Also greater friction on the outward stroke of the friction element is produced by reason of the fact that the pivoted arm 20 forming the friction element, extends from its pivot 21 to its point of engagement with the sparking element 17 at a downward angle to the guide tube 11, guiding the slide 19, the tendency being. as may be seen by the drawings (Fig. 2). to push the roughened friction surface into firmer contact with the sparking element 17. The friction element 20 is maintained in frictional sparking engagement with the sparking element 17 by a stiff flat spring 22 shown as secured at one end to the outside of the tube 11 by a band 23 and which at its outer end presses against the smooth back surface of the free end of the friction lever 20.

If the slide 19 be drawn inward from the position shown in Fig. 2 and then rapidly moved outward. no sparks will be produced by the inward movement but a shower of sparks will be thrown off from the sparking element 17 during the outward move ment. Mechanism is provided for impart ing such movements to the slide 19.; this mechanism being conveniently operatable by the same hand that grasps the handle 14. A second slide or lower slide 24 is located in the longer guide tube 12 adjacentto the handle 14 and is connected with the upper slide 19 by a slightly flexible bent rod 25 shown as screwed into the slide 24 and as pivoted at its upper end to the lower end of the slide 19 by a pivot pin 26 passing through a slotted reduced end portion of the slide 24 receiving the flattened end of the rod 25. Because of the length of the lower straight portion of the rod 25 within the longer tube 12 and the flexibilityof this rod, there is no need for a pivotal connection of such rod with the lower slide 24. Because of the fact that the rod 25 is bent at an obtuse angle and is of considerably smaller diameter than the internal. diameter of the tubes 11 and 12. the rod 25 is permitted to reciprocate in the tubes Witll'. out appreciable friction therewith.

A strong coil thrust spring 27 is adapted to quickly move the slide 24 upward and thereby produce frictional sparking engagelower end of the lower slide 24 and guided at its lower end in a central hole in the abutment plug 28. The spring27 should preferably be under some initial tension .to assure that it will impart a strong sparke ing movement to the friction element 20.

Trigger mechanism is provided for drawing downward and automatically releasing the slide 24, thereby com ressing and releasing the spring 27'. uch mechanism comprises a toe 3O pivoted by a pivot pin 31 in a bracket 32 secured to the tube 12 adjacent to the handle 14. The toe 30 passes through a slot in the side of the tube 12 and has a rounded end engaging in an opening in the slide 24, as shown in Fig. 2. The upper edge of the slot in the tube 12 and a cross-piece on the bracket 32 serve as a stop for the toe 30 and thereby limit the outward movement of the slide 24 and limit also the expansion of the spring 27. The outer pivoted end of the toe 30 is bifurcated and between the prongs of the bifurcated portion a pawl 33 is pivoted on the same pivot pin 31 as the toe 30 and extends downward within the sides of the bracket 32, the pawl 33 having a pivotal'lost motion engagement with the toe 30, as indicated in Il ig. 2. A trigger 34 is pivoted in the bracket on a pivot pin 35 and has a short lever end adapted to engage the dependingthe bracket 32 and another extended portion Y 38 engaging the pawl 33, (Figs. 2 and 6).

In operation, the thumb piece of the trigger 34 is depressed toward the handle 14 and the inner end of the trigger will engage thd pawl 33 and actuate the toe 30 to retract the slide 24 and compress the thrust spring 27, the friction element 20 being also retracted by the slide 19 and actuating rod 25. When the trigger 84 has been sufiiciently depressed,itsshorter inner end will slip past the end of the pawl 33 and thereby release the thrust spring 27, which, by reason of the connections already explained, will move the friction arm 20 quickly outward over the surface of the sparking element 17, against which it is pressed into frictional engagement by the spring 22. A shower, of sparks, which will readily ignite illuminating gas,

.will be projected outwardly.
