T0 all 'whom it may concern Be it known that I, DAVID J. CANoHEsTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and' useful Improvements in Igniters, of which more specifically set forth .in the subjoined claims. l

In my igniter, I employ the well known elements of a striking- -or scraping body having a roughened surface, and a body of spark-producing material contacting with the roughened surface to produce sparks. The sparks thus produced may be projected against any explosive gas or any other body of material which is desired. If, however, a iame is desired instead of sparks, I provide a wick and suitable means, for supplying the wick with a volatile liquid whose the liquid and the gases emanating theregas is highly inflammable, together with means for directing a shower of sparks against the wick to ignite it.

I preferably embody my invention in an elongated cylindrical case, readily inserti-ble in the ordinary pocket of wearing' apparel and composed of two main members, a bodyportion containing the wick and receptacle for an inflammable liquid, and a cap'portion slidably hinged to the body portion and containing the spark producing mechanism. By the interposition of a wall of metal be-k tween the spark-producing mechanism and the chamber for inflammable liquid, Isepa'- rate the spark-producing mechanism from from. I i

The production of sparks from my' is preferably accomplished bythe mere oscil- A lation and release of a small lever. In my construction, Iposition the spark-producing device above the wick holding portion of' the case and in na chamber separated from the Wick Chamber, 'but when it ie de ered t@ light -the'wick the cap may be removed from 1ts position upon the body portion of the case, swung upon its hinge and lowered to such a position that the shower of sparks lwill be projected directly across the wick to ignite it, The hinge pivot is secured at its upper end to a lug upon lthe cap, and free toslide 1n a lug upon the body portion of the case. Preferably the hinge pivot dependsbelow the lower, or 'body-lug', ,and

bears a small ball at its lower extremity; thus forming a convenient cllip for securing the igniter in the pocket of the user.

In the drawings: Figure 1 is a side elevation of my invention; Fig. 2 is an enlarged vertical section of my invention showing some parts in elevation; Fig. 3 is an elevation. of my invention showing an adjusted position of the `parts; Fig. l.Lis a view of a portion of my Invention showing parts of the case broken away, a portion of the caseJ in section and anelevation of portions of a spark-producing device; Fig. 5 is a section taken on the line 5-5 of Fig. 4 and looking in the direction indicated by the arrows; Fig. 6 is a top plan View of a portion of a spark-producing device showing the casing of my invention in section; Fig. 7 is a side elevation of a portion of the spark-producing device showing parts of my invention broken away and parts thereof in section.

The casing of my invention is formed of two main portions, the lower voff which is indicated by reference numeral rl() and the upper one vby 11. The two parts of the casing are preferably so constructed that the portion fl1 descends about and is removably iiXed in relation to the lower portion 1'0. The' casing 11 is -provided with a lug 12,

to whichl is rigidly secured a hinge pin 13'.

The lower'portion 10 of the casing bears an apertured lug 14,. through which the hinge pin 13 passes and in which the hinge pin is, free to slide. The hinge pin 13.projects below the lug 14C, as at 15, and preferably' bears upon its lower extremity a. globular enlargement 16, the extremity 115" and Athe enlargement 16 constituting a pocket' clip for securing my invention to the ordinary pocket in wearing apparel.

Preferably,- the inner ldiameter of the cas- I 'is' vsufficient to Aallow it to descend upoppthe. upper extremity of the casing 10 appjijremovably' Isecure;the two together. A

sheathed together their respective chambers are separated and the liquid and gases; contained inthe chamber of the member cannot pass into the chamber of the'member 11.

Secured in the member 11 is the sparkroducing portion of my invention. The rame 18 of the spark-producing portion lis secured to the casing 11 preferably by the ordinary well-known means of pins 41 and bayonet slots 42. Two arms 19 and 2O de-v pend from the frame 18 at diametrically opposite sides thereof, and a horizontal pin 21 is rigidly secured at each of its ends' in one of these arms. A centrally bored wheel lshaft 22 is mounted for oscillation upon the pin 21 and is slotted, as at 23, from its outer to its inner periphery, the slot being of suiiicient size to admit of the insertlon of a spring `membe'r 24. Mounted for rotation upon' the'wheel shaft 22 and disposed preferably in the center of the casing 11 is a striking wheel 25, the outer eriphery of which is roughened preferably y serrations 26. The center of this wheel is' cut away and the innerl periphery bears a plurality ofratchet points 27. The spring member 24 is blo at one of its ends secured .in fixed relation tothe wheel shaft22 and its free end extends out of the slot 23 for engagement with the ratchet points 27, sufficient room being allowed between the outer periphery ofthe lwheel shaft 22' and the ratchet points 27 to admit of the passage of the spring member 24. The free end ofthe spring member 24 is adapted, when the wheel shaftis turned in one direction, to press against and slide upon the inner periphery of the striking wheel 25 and when the wheel shaft 22 is" turned in the opposite direction the free end of the spring member 24 contacts with the 22 and the strikin wheel 25 into fixed relation and causing t e strikin wheel to'oscillate with the wheel shaft. e oscillation of the wheel shaft 22 is accomplished by the manual Swingin of a lever 28, which is secured to the en 29 of the wheel shaft 22 and extends without the casing 11, a slot 30 bein provided in the casin 11 for the oscil ation of the lever 28.. o provide a smooth bearing surface for the hand o'f the operator, I preferably place a globular enlargement 31 or other smooth end upon the outer extremity of the lever 28. A tension,

spring member 32 is given a convenient number. of loose turns around the wheel shaft 22, and has one of its-.ends xed in relation'to the arm 2O of the frame 18 and its o posite end secured in relationv to the wheel aft 22. The downward oscillation ofl the ratchet points 27, locking the wheel shaft lever 2-8-.turns the wheel shaftv22 upon th`\ v4 pin 21, sliding the spring member 24 within the striking wheel 2 5 to a point where it slips over and contacts with one of the ratchet points 27. This oscillation of the lever 28 places tension upon the spring member 32, and the removal of the hand of the operator from the lever 28 releases the power thus'stored inthe spring member 32, causing the wheel shaft 22 to oscillate in a .reverse direction carrying with it the striking wheel -25 to which" it is locked by the spring member 24.' In this manner, a sudden and violent rotation of the striking wheel 25 is obtained. For securing one end of the tension spring 32 in fixed relation to the wheel shaft 22, I preferably employ a washer 33 embracing the wheel shaft and keyed thereto as at 35, the end of the spring member 32 being positioned against an offset lug 34 upon the washer 33'. A

The frame 18 is centrally bored, as at 36, for the insertion of a piece of spark-produ@ ing material 37. A cap`38 in threaded enagement with the up er` extremity of the rame 18 forms a stop or one end of a compression spring member 39, the opposite end 4 of which bears against the spark-producing apiece 37 forcing it downward intolcontact with the striking wheel 25. Adjustment of the pressure of the piece 37 against the wheel 25^is obtained by turning the cap 38 -upon the frame 18.v -The violent rotation ofl the striking wheel 25 above described causes its serrations 26 to chip particles of sparkproducing material from the piece 37 and projects the sparks thus formed through an opening 40, provided therefor in the casing 11. c

Achamber 43 is formed by lthe casing 10 and contains a wick 44 secured in position within the chamber preferably by a packing of an yabsorbent material 45, suchA as cotton. A web 46 forms a closure for the lower extremity of the chamber 43,' and the body portionv of the casing 10 extends below the web 46, as at 47, to form a socket or any other suitable device for convenience in se4..

curing penci or any other desired article. A collar my invention to the end of a pen,'.

48 is rovided for the uppei extremity of.

"the wick 44'for convenience m vmaintaining this end of the wick in its proper position in the chamber. 43 and slightly elevated' the upper extremity ofthe wick, the casing .izo

10 is cut away as at 50 to allow the passage of a shower of-sparks from the spark-proj ducing device to the wick. v j

In the operation of my invention, the manual oscillation of the lever 28 as heretofore described produces a shower of sparks, which are projected without the casing 11 through the opening 4:0. If it is .desired to ignite a substance which will burst into flame by contact of hot sparks, thev opening is placed adjacent the substance to be ignited, the lever 28 oscillated andreleased and the resulting shower o'f sparks directed toward thesubstance.. If, however, a flame is desired, the casing 11 is unsheathed from its position upon the casing l() (as in l), turned upon its hinge and lowered until it assumes the position shown in Fig. 3 beside the upper portion of be raised, swung upon its hinge and replacedin its position upon the'casing 10. In the accompanying drawings and in the foregoing description are set forth the preferred embodiment of my invention, but

it is obvious that one skilled in the art may make modifications thereof without departing from the principle of the invention.
