IGNITJER.

To all whom it may concern:

Be it known that I, LOUIS V. ARoNsoN, a citizen of the United States, residing at Newark, in the county of Essex and btate of New Jersey, have invented certain new and useful Improvements in Igniters, of which the following is a specification.

The invention relates to gas igniters, and has as an object the provision of an igniter for lighting gas burners Which will have a long life for use, which will be convenient to use, and which will give a brilliant shower of sparks for the purpose.

An illustrative embodiment of the invention is shown in the accompanying drawinofs, in whichligure l is a side elevation;

Figure 2 is a plan view and Figure 3 is an exploded detail perspective view of portions of thedevice.

As shown in 'Fig. 1, the device comprises a frame 10 constructed of a single piece of material, being bent into a downwardly directed loop 11 to provide a handle, an upper horizontal portion 1 2 to which the trigger 13 is pivoted, a portion 14 downwardly offset from the portion 12 and extending horizontally forward, and extremity 15 of the material'being doubled backward upon the portion 14 and turned downwardly at an angle thereto.

The second end of the material 16 is turned upwardly at an angle to a lower horizontal portion 17 and the

vertical portions

15 and 16 are perforated by means of slots 18-19.

A reciprocating member 20 is adapted'to slide through the slots 18- and 19 and, 'as shown, carries a friction member 21, shown as a piece of file secured' at its forward end as by being seated in a recess 22 and by having portions of the material of the member 20 upset over it as at 23-24. To return the member 20 to the position shown in Fig. 1 a coil spring 25 is shown surround- .ing the member 20 seating against the portion 16 of' the frame as an abutment and acting upon the, member 20 by seating against a pin 26 passed therethrough.

To retract the member 20 the trigger 13- havng an end 27 passing through a slot 28 .ward movement in contact with the in the frame acting as a fulcrum and also working through a slot 29 in the member 17 of the frame, has a pin 30 coacting witl a notch 31 in the member 20.

As the trigger '13 is moved to the rear by the fing'er of the user the pin 30 will travel in the arc of a circle and the member 20 will be moved to' the rear until its extremity 32 abuts against the' ortion 33 of the frame when its rearwar motion will be checked. At this time the pin 30 wili be on the portion of its arc which iscurving upwardly and continued motion of the trigger will release the pin from the notch 31, allowing the member 20 to be snapped to its normal position.

A cylinder 34 is shown as mounted in the `forward end of the portion 14 of the frame,

and a piece of pyrophoric material 35 is mounted upon a loop 37 s'ecured to the porv tion 14 of the frame, the loop 37 passing through the coils 38 of the spring. An end of the spring is seated in a perforation 39 in 'the frame and the other end 40 seats in slots 4:1 in the cylinder 34 and presses upon the end of the pyrophoric material 35. The friction element 21 by its sudden for- PYI'O' phoric vmaterial will produce a brilliant shower of Sparks sufficient to readily ignite a gas burner.

To return the trigger 13 to normal position after ignition of the member 20 a coil spring 42 is shown anchor'ed ,upon an e2- tension of the pin 30 and in an opening 43 at the base of the portion 16 of the' frame. The member 20 bein pressed downwardl) by spring 36'at' its orward end will have a fulcrum in thev lower end of the slot 19, causin the portion bearing the notch 31 to be resi iently pressed upwardly. When the trigger 13 is' returned the member 20 will be presseddownward by the pin 30 with yielding of spring 36 until its position over housed in the frame and since the slots 18-19 are also centrally placed in the frame, the member 20 is provided with a lateralofi'set at 44:, so as to bring the portion of the member 20 opposite the trigger to one side of the trigger.

Minor changes may be made in the physical embodiment of the invention Without departing from 'its spirit.

I claim: f

1. An igniter comprising, in combination, a frame comprising a pair of spaced vertical portions having slots therein, a reciprocatiig member acting in said slots, a spring abutting against onev of said portions and against an element of said reeiprocating member to return said member to normal, a trigger pivoted in said frame having an element coacting With a notch in said member, said member adapted to contact'with a portion of the frame at the rearvvard limit of its motion Whereby the trigger is released from the member with sudden return of the member to normal position, a friction element moved by said member, a pyrophoric element in contact With said friction element.

2. Aniigniter comprising a frame formed of a strip of material bent to form a handle loop, a horizontal portion and a pair of spaced portions extending perpendicular to dsaid horizontal portion, said last named portion having slots, a reciprocating member mounted in said slots and extending into the handle loop, a spring anchored to one of said spaced portions to return said member to normal, a friction element actuated by said member, a pyrophorc element carried by said horizontal portion in contact with said friction element, means mounted in the frame to actuate said reciprocating member.

3. An igniter comprising a frame, a notched reciprocable member' mounted in the frame, a portion of the frame adapted to limit the movement of the member from its normal position and to deflect the member laterally at the end of its movement from normal, a trigger having an element coacting with the notch in said member vand aadapted to release said member When its limit of movement from normal is reached, a 'spring to return said member to normal, a friction element actuated by said member and a pyrophoric element in contact with said friction element.

4. An igniter comprising a strip of material bent on itself to form a loop, a portion of the loop bent dovvnvvardlyl to form a handle and a portion thereof extending for-` Wardlyand having slots in, its members, a portion of said strip extendin forWardly from said loop, the end of sai forwardly extending portion doubled on itself and the extremity bent downwardly and slotted, the other extremity of the strip bent upwardly so g toward the forvvardly extending portion and 'Louisv.
