A Trae/viv Patented Apr. 12, 1932` yA RTIHTJ'B. 5'.y FAUSEK AND IRWING F.V FAUSEK, OFCLAYTON, MISSOURI LIGHTING DEVICE i Application led March 30,1931.. Serial No.526,361.

This invention` relates to lighting devices of the sparking type heretofore employed in igniting gas and other combustibles and more specically to an improved lighting device of this type which is designed so as to more efficiently perform its function than did similar devices heretofore known, the predominant obj-ect of the invention being to provide an improved lighting device of the type referredto which is provided with a plurality 'of sparking `elements adjustable successively into operative position relative to an'abrasive member whereby the period of time during which the device may be used before it is necessary to renew the spark producing means thereof is very greatly increased.

Lighting devices of the type disclosed here-y in are used extensively in igniting the gases issuing from gas-burning cutting and welding torches, and considerable annoyance `was causedby the fact that the devices heretofore employed for this purpose each included a single sparking element which very quickly was consum-ed by repeated operation of they lighting device and hence had to be frequently renewed. To eliminate this annoyance we have devised the improved lighting devicedisclosed herein. which, briefly stated, includes a plurality of sparking elements which are adjustable successively into operative position relative to the abrasive member of the device'. The operationzof adjusting anew sparking element into operative position after a previously operative sparking ele-l ment has been consumed is anextremely simple one, hence, the device may be maintained in operative condition with a minimum effort for a much greater length vof time than was possible in the ,use of the lighting devices heretofore employed.' y f v Another feature ofthe invention resides in the fact that the sparing elementsfof our improved device are coated with a preparationy which prevents rapid decompositionof said.

elements. This feature is i important inasmuch as these elements are highly susceptible of rapid decomposition prior to being placed in use because of Contact of air` therewith and K by coatingthe elements as described the effective life of said elements is very substantially prolonged.

In the drawings, wherein is shown forthe purpose of illustration, merely, one' embodiment of the device ,and two embodiments of the sparking elements thereof, A designates the devicegenerally, said device including a handle portion 1, an abrasive member 2 which is supported by 'a portion of said handle v1,

and Ha plurality of sparking elements, or ints, 3 supported by another portion of the handle l in a manner to permit of one'of said sparking elements being moved with respect to and in Contact with said abrasive member so asto produce sparks. The handle l preferably is formed from a strip of metal, or other suitable material, which isr possessed of considerable resiliency, said strip of material being bent to assume a substantially U shaped form as shown in' Fig. l and with a bowedr connecting portion l? at the outer end of the handle. For the purpose of convenience 2 is an venlarged section on line 2-2 l' in describing the invention we designate one leg portion of the handle by the reference character lb and the other leg portion thereof by the reference character 1.

The end portion of the leg portion 1b of the handle l opposite the end thereof which joins the bowed connecting portion la is shaped as clearly illustrated in Fig. lof the drawings; that is to say a yoke 4 is provided which is comprised of oppositely disposed side walls 4a and 4b and a top or end wall 4c which is formed integral with said side walls 4 and 4h. The yoke 4, in the embodiment of the invention illustrated in the drawings is integrally joined to the leg portion 1) of the handle 1 by an inclined connecting portion 5 whereby the handle 1 and the yoke 4 provide a unitary structure. Also the side wall 4b of the yoke is elongated as indicated at 6 in Fig. 1 for a purpose to be hereinafter set forth. f 1

Supported within the yoke 4 is a box-like structure 7 whichhouses the abrasive member 2 of the device, said box-like structure comprising oppositely disposed end Walls 7, top and bottom walls 7* and 7c respectively, and a back wall 7d. The walls referred to produce an integral structure which is open at the front as shown clearly in Fig. 2, the top Wall b of this structure preferably being of less width than the bottom wall 7 c and being in contact with the inner facey of the wall 4L of the yoke 4. The abrasive member 2, which may formed of any suitable material such as metal or the material known commercially as Lava, is provided with an opening 2 which extends longitudinally therethrough from end to endthereof,-and the end walls 7'a of the box-like structure 7 are provided with openings 8y which are alined with said opening 2. In like manner the side walls 4a and4bof the yoke structure are provided with openings 9 formed therethrough which are alined with thel opening 2 formed through the abrasive member and the openings 8 formed in the end walls of the boxlike structure 7. Extended through the alined openings 2, 8, and 9 in the abrasive member 2,` yoke 4, and the box-like structure 7 is a bolt 10 which is provided with a head portion 1()a at one end, and a screwthreaded portion at the opposite end which receives a nut 11. The nut 11. is screwed inwardly on thev screwthreaded end portion of the bolt 10 so as to cause said nut and; the head portion of the bolt to lfirmly contact with the side walls 4a and 4b whereby the yoke 4 and boxlikeV structure 7 are securely fixed together and the abrasive member is maintained in its proper position.V

The end portion 12 of the leg portion 1c of the handle 1 is twisted with respect to the remainder of said leg portion until the width of said portion 12 is disposed in a vertical plane which is approximately parallel with respect to the axis of `the abrasive member 1. Also this portion 12 is provided with an extension 12v at its upper end which isr shaped as shown in Fig. 1., The portion12- is alsoy provided with an opening 13 through which a screwthreadcd bolt 14 is exten ded, the head portion- 14 of said bolt being in Contact with the outer face of the portion 12 and being permanently secured to said face by solder or other means 14a.

Rotatably supported by the bolt 14 in contact with the inner face of the portion 12 of the leg portion 1C is a head 15 which is provided with a plurality of radial arms 16. Also said head, at points intermediate the arms 16 is provided in an edge portion thereof with a plurality of notches 17. The portion 12 of the leg portion lC is provided with a pin 18 which extends inwardly from the inner face of said portion 12, said pin being provided with a reduced portion 19 which is disposed in an aperture formed through the portion l2 and is rivetedk in place therein whereby said pin is securely fixed in place. AsV shown very clearly in Figs. 1 and 3 the lowermost notch 17 of the head 15 embraces the pin 18 in a manner to prevent unintended rotation of the head. 15 about the bolt 10. At the outer end of the radial arms 16 of the head 15, we arrange the sparking elements 3 of the device, there being one sparking element' supported by each arm and said sparking elements are fixed in place in any suitable manner, as, for instance, by having end portions thereof driven into apertures 20 formed through the arms.

Mounted on the screwthreaded end portion of the bolt 14 is a nut 21 which is provided with an elongated sleeve 21. T he inner end of the sleeve 21" ofthe nut referred to may be screwed into close contact with theV head 15 so as to force said head into firm contact with the inner face of the portion 12 of the leg portion 1c of the handle 1. It will be noted by referring to Fig. 1 of the drawings that the downwardly extended portion 6 of the side wall 4b of the yoke 4 serves as a stop with which the sleeve 21 ofthe nut 21 may contact to prevent undue outward movement of the portion of the leg portion 1 which supports the sparking elements. Also as shown in Fig. 2 the head portion ofy the nut 21 overlaps the box-like structure 7 whereby the end of the leg portion 1c which supports the sparking elements is prevented by contact of said head portion of the bolt with the rear wall of said box-like structure, from springing in a direction away from the abrasive member 2.

The portions 22 of the handle which are grippedy when the device is being operated are preferably curved slightly in a transverse direction as indicated in Fig. 4. Also these portions 22 are disposed at such angles that when pressure is applied, in a manner to be hereinafter described, to cause the effective sparking element 3 to move longitudinally in contact with the abrasive member 2, such pressure, because same exerts a force at a right angle to the planes of portions will cause the effective sparking element to be forced rmly against the face of the abrasive member. In order to aid the natural resiliency ofthe handlefwe may, ilr desired, provide the device with a spring suchas that designated by the reference character 23.

ln the operation of the device the uppermost sparking element 3, Which isthe effective sparking device and which is arrangedat all times With itsouter end in close Contact` with the face of the abrasive'member 2, is moved longitudinally lof the rabrasive `member in close Contact therewith with the result that sparks are produced. VrSuch movement of the effective sparking element is produced by grasping the handle of the device inthe hand and quickly moving the leg portions 1b and 1c toward each other. After this operation has been pertormedrepeatedly itl Will be found that the 'etiectivesparking element has been practically consumed, and heretofore it Was necessary to obtain a new sparking element and perform the time consuming task of removing the stub otthe old sparking element and replacing same With nen7 sparking element. In the use .ot our improved device, however, it is necessarygto merely unscreiv the nut 21 topermit the lowermostnotch 1T to be freed trom thepin 18 by moving the head longitudinallyy ot the bolt le. The head` 15 may then be rotated to bring a .new sparkingelement into eliective position adj acent to the abrasive member Q-at which time another notch 17 will embrace the pin 18. The nut 21 may then be screwed inwardly on the bolt li, whereby the inner end ot the sleevefQl et said nutV Will torce the head against the inner :tace of the portion 12 of the legV portion 1 ina manner to prevent disengagement of the lowermost notchf17 from the pin 18 resulting in securely fixing the head 15 in place.

The abrasive member 2 is preferably round in cross-sectionand is capable of rotation on the bolt l0 and in order to induce such rotation We may provide the abrasive member with a spiral groove 24. rl`he edect of the presence of this spiral groove is that the etgrooves 25 spaced longitudinally et rthe abrasive member. ln the use of this tormci" the device also the sharp corners at the Walls ci the grooves produce an improved sparking effect.

In order to preserve the sparking elements,

particularly before use thereof in the device, and prevent decomposition thereofy caused by the contact of air therewith We pr ter tocoat vsaid sparking elements with a suitable sub-- stance, such, for instance, as lacquer, varnish, or shellac as indicated at 3 in Fig. 6.
