GAS-LIGHTING DEVICE.

- Specicaton of Letters Patent.

Application led October 20, 1911, Serial No. 655,721.

To all 'whom t may concern: v

Be it known that I, THOMAS J. LrrnE, Jr., a resident of Woodbury, in the 'county of Gloucesterand State of New Jersey, have invented a new and useful Improvement in Gas-Lighting Devices, lof which the folloW ing'is a full, clear, and exact description, referencejfbeing .had to the accompanying drawings,form ing part of this specification, in which Figure l is a side view showing one form of my invention applied to a gas lamp of the inverted incandescent type with the gas valve in closed position; Fig. 2' is a view partly y in elevation and partly in vertical sectiontaken at right angles'to Fig. 1, but showing the gas valve in its Vopened positionylig. 3 is a detail view showing the holder'-"for the pyrophoric alloy abrader; Figt-fis" a side view showing another form of my invention applied to a lamp; and Fig. 5 is a detail sectional view of a portion of the device shown in Fig. 4.' l

My invention has relation to gas-lighting devices adapted fora use in connection with gas lamps, gas stovesyand, in fact, any type of gas-burning appliance. My invention relates more particularly to that class of gas-,lighting devices which employ a pyrophoric alloy, which has the property of emittingver` hotv sparks when scratched by a hard s Ibstanoe.

A particular object of my invention is to provide an v4at' ment. of this character which, when ac edgwill first open the gas valve and will then l:produce the ignitlng sparks, andwhich w-il compel a pause by the operator between two Operations of snjtlicient lengthto ins e the gas reaching.

the igniter at theitime the sparks are produced. Prior to my invention, it has been proposed to employ a rotary device for effecting phoric alloy and for the opening of the gas cock, but such a device has not proven satisfactory in operation, because the twisting or turning movement is a very quick one and the sparks are produced before the gas reaches the point of ignition and it is difficult to instruct or accustom the user to hesitate in the middle of the operating movement. If a simple reciprocating movement be used, the same disadvantage exists and such a device is also open to the objectlon the scratching or abrading of pyrothat there is a sharp, rasping motion of the abrader over thepy'rophoric material which results in jarring the gas fixture and the frequent breakage of the fragile mantle when thedevice is employed `in a lighting burner. My invention overcomes these objections' byV providing a device which requires two-separate movements for its operation and which will compel a pause on the part of the operator between such movements. The first movement opens the gas valve, while the second movement scratches the pyrophoric alloy and produces the spark.

In the accompanying drawinos, I have shown my invention appliedbo aIamp ofthe inverted incandescent type, but as above indicated, my invention is not limited' thereto.

In these drawings, the numeral 2 designates the body of the burner having a shadeholding ring 3 and a gas-supply tube 4, which 1s provided with a controlling valve 5.

6 designates the burner; 7 the mantle; and` 8 the globe or shade.-

9 designates the ignition tube or opening where the spark'vmeets the gas and ignition takes place. l

10 designates a de'lector for deiecti `g the gas upwardly to its opening.

In Figs. 1 to 3, the-numeral 11 designates the holder for the piece 12 of pyrophoric alloy, this holder being shown as secured to the ignition tube 9. It has a horizontally extendin seat portion 11?, on which the block 12 1s slidably seated, being pressed toward a serrated or roughened abrading -Wheel 13 by means of a spring 14. The

wheel 13 is secured to the up er l abrading n end of a small shaft 15, which 1s )ourna ed at its upper' portion in the holder 11. 16 is Patented nem-10,1912.'

a sleeve which has a sliding telescoping 4engagement with the shaft 15, and to the lower end of which is hingedly connected the' pg.

tuating rod 17. The hinge connection tween the parts 16 and 17 is preferably effected by a universal joint 18.- The member 17 preferably terminates-at its lower end in a suitable button or sleeve 16 has a longitudinal slot 16 toreloeive a pin 16b on the shaft 15, whereby the sleeve will move freely on the rod, but will be 1fixed thereto with respect to rotary mogel ment. 20 is an actuating connection tween the sleeve 16 and lever arm 21on the stem of the gas valve 5. i,

finger piece 19. 'The The operation is as follows: dien the burner is not. lighted,l the parts are in the position shown in Fig. 1. To light the burner, the operator takes hold of the linger piece or button- 19 with his fingers .and

'pushes upwardly on the rod 17.A During this movement, the sleeve 16 slides upwardly on the rod 15 and the gas valve is opened by the movement ofthe connecting member 20. When the pin 16" reaches the lower end of the slot 16,further upward movement of the vactuating rod is stopped. The operatorl then gives a turningmovement to the rod 17, causing the toothed or serrated Wheel 13 to exert 'an abrading action on the pyrophoric alloy, thereby producing a series of hot sparks at the orifice of the ig'- nition tube 9. y

In the construction shown i'nFigs. 4 and 5, the abrading wheel 13a is connected to a sleeve 30,1rotatably mounted in bearings in a bracket 31, 'connected to theignition tube Qa@ Mounted for reciprocal and rotary movement withinl the sleeve 30 is a rod 39..

Connected-to oneend of this rod f is the valve-actuating connection 20a, .and hingedly connected to the otherend 'thereof is the actuating rod 17a.- The'lowerend of the` sleeve is provided with a plurality. of ratchet teeth y33, and 3,4 is' a'pin extending-through the rod 32 which is arranged'to engage the teeth 33 when the rod is mov-,ed upwardly to open the gas valve. Theteeth 33 are so shaped that the sleeve 30 and the abrading 'Wheel can only be rotated in one 'direction by saidpin. The operation of this deviceis the same as that shownin Figs. 1 to 3, eX- cept that the abradin'g can not be operated by the actuating rod until the gas valve has beenmoved. to itsfull open 'positicn by said actuating rod, and at whichV .time the; pin 34 will engage the teeth 33.

The pause or interval which naturally oc curs on the part of the operator'between' the end. of the reciprocating valve-opening movement and the commencement of the rotary spark-producing movement is just sufiicient to insure the gas reaching the ignition opening. This pause the operator is compelled to make'in operatingthe device, andas above stated, lit is this feature which.

broadly characterizes my"inyent ion. long as this feature is present, it will be obvious that the details of the actuating mechanism and ofthe arrangementof the pyrophoric alloy and of its abrader may be Widely varied to suit `the particular character of the burner in connection with which the attachment is' employed, without departing from the spirit and scope of my inven tion, as defined in the A appended claims.
