Specification of Letters Patent.

Patented June 6, 15'1 Application filed December 22, 1910. Serial No. 598,732.

To all whom it may concern.

Be it known that we, Josnr JE'RGLE, KARL MACi-IAL, and JULIUS HELLER, all'subjects of the Emperor of Austria Hungary, residing at Vienna, Empire of Austria- Hungary, have invented certain new and useful Im-' pro'vements in Igniters for Gas-Burners; and we do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to igniters for gas burners of that class in which an abrading body is moved over a spark producing body such for instance as a body made of an alloy of iron and cerium, whereby sparks are produced. "On starting the abrading body gas is admitted to a sm ll igniter tube and nearly at the same time a so to the burner proper. The sparks produced ignite the gas issuing from the igniter tube and the flame thus obtained ignites the gas issuing from the burner proper. Then the abrading body has completed its movement the gas supply to the igniter tube is cut off.

According to this invention a disk carrying the abrading body and journaled in the burner frame is connected with both arms of a two armed lever secured to the gas cock so that the movement of the said lever serving for opening the gas cock is directly transmitted to the said disk. Thisconnec tion may beeffected by a rope or chain, by links or the like or by a spring and a slotted link. Inthe two first named cases when the lever is moved continuously the disk moves continuously too. In the last named case, however, when the lever moves continuously in one direction the disk is arrested at a pre determined point of its path by a stop spring the lever continuing to move putting under tension the actuating spring. After the lever has thus moved through a certain angle the disk is released and the disk moves under the act-ion of the distending actuating spring with increased rapidity.

In the annexed drawing Figure 1 is a side elevation of the present improved gas igniter. Figs. 2, 3 and 4 are similar views showing modifications.-

Like numerals of reference indicate similar parts in all the figures.

1 is a disk carrying or constituting an abrading body as shown, the abrading body consists of a set of teeth provided on the periphery. of the disk. This disk is journaled at 5 on the body 2 of the burner. I

3 is the spark producing body such as a piece of an alloy of iron and cerium mounted on the burner body 2 in the usual way.

4 is a. small igniter pipe through which escapes the gas to be ignited by the sparks.

6 is the lever serving for actuating the gas cook. The movement of the latter is directly transmitted to the disk. In the construction shown in Fig; 1 this is done by means of a pulley 8 fast on and concentric with the disk 1 and a cord, chain or perforated band 7 on such pulley and having its ends secured to the lever 6 at opposite sides of its fulcrum.

In the modification shown in Fig. Qthe disk is connected to the lever 6 by links engaging pins 9, 9 on opposite sides of the lever 6 and pins 9" 9 on opposite sides of the journal pin 5 of the disk.

In order to insure a suflicient admission of gas to the igniter tube 4: prior to the setting up of the sparks which is necessary for the reliability of the device, it is preferred to offer a. resistance to the movement of the cock in the beginning of its motion by means of a stop spring or a tilting weight which in the latter part of the motion of the lever when the sparks have to be produced acts to accelerate the lever during the first part of the motion of the lever when this moves slowly a continuous gas current is set up, while by the rapid movement of the disk toward the end of the lever motion efficient sparks are produced.

y In the modification shown in Fig. .3 one arm of the lever is connected with the disk by means of an actuating spring 11 engag: ing pins 12 and 12 on the disk and the lever respectively. To the other arm of the lever 6 there is pivoted a link 13 having a slot 14 at its outer end engaging with a pin 15 on the disk. A stop spring 16 is secured to the burner frame the free end of which is in the path of a stop pin 17 on the disk. In the position of the cock lever 6 shown in the drawing the gas cock is closed. If now the gas cock is opened by pulling down the left hand end ofv the lever 6 in the well known manner the disk 1 with the abrading body is moved through the medium of the cord or chain as shown in Fig. 1 or through the medium of the links 10 as shown in Fig. 2. Sparks are thus produced by the body 3 and ignite the gas issuing from the small pipe 4.

.In the modification shown in Fig. 3 the disk 1 first turns together with the lever until the stop pin 17 strikes against the stop spring 16. 'As the lever continues to turn' While the disk is arrested the actuating,

spring 11 is put under tension and the pin 'slides along the slot 14 until it reaches the end of the latter so that the disk and the cock lever are then rigidly connected.

' Consequently the disk is then turned together with the lever the stop spring 16 being pushed back by the stop pin 17 thereby releasing the disk 1. This disk moves then. under the action of the actuating spring.

arrested, for causing the disk to be released before the cock l ever has completed its move ment. When the 'cock is returned into its normal or closed position by the'lever 6 no sparks are produced owing to thewell known arrangement ofthe abrading body or surface.

Fig. 4: shows a modification of the construction shown in Fig. 3. In this modification the part 18 of the periphery of the disk 1 which at the beginning of the movement of the cock moves past the spark producing body 3 is smooth and slightly deeper or nearer the center of the disk than the points of the teeth constituting the abrading body.

In the firstpart of the opening movement of the cock the smooth portion 18 of the disk 1 passes in front of the spark producing body, so that the disk moves along with the' cock until the first tooth 19 of the abrading body strikes againstthe spark producing body whereby an increased resistance is offered to the movement of the disk and the latter is temporarily arrested while the lever ,6 continues to move, Therebythe .tension of the spring 11 .is increased until it overcomes the resistance offered-to the further movement of the disk by the body 3. Then the diskbegins to move again with increased speed, whereby eflicient sparks are produced. The restarting of the disk after this temporary stopping of the same may be assisted or brought about positively by the slotted link 13 as described with reference to Fig. 3.

In the arrangemel'itshown in Fig. [the stop spring 16 and the stop pin 17 is dispensed with, the wear of the spark producing body is reduced and the movement of the parts is more smooth.
