AUTOMATIC GAS-STOVE I..IGH'1111131k Application led October 31, 1927. Serial No. 230,011.

This invention relates to automatic igniting devices and pertains particularly to an automatic ignitor designed for use in connection with gas stove burners.

The primary objects of the present invention is to provide, in a manner as herein after' set forth, a device designed to ignite a gas burner orr similar g'as fixture, automatically and simultaneously with the turning onof the control valve.

Another object of the invention is to provide, in a. manner as hereinafter set forth, an automatic ignitor which, when the gas fixture in association with which it is used is in use, will act as a pilot to re-light the fixture in the event that the same is accidently put out.

The invention has for another object the provision of an automatic lighting device for use in association with gas fixtures, wherein a gas jet is ignited independently of the lixture and acts to light the fixture when the control valve thereof is turned on, the lighting` jet continuing to burn while the fixture is in use and acting in the event of accidental extinguishment of the fixture, to re-light the same, the jet being so located and protected that the possibility of it being extinguished, is very slight.

A further object of the invention is to provide an automatic lighting means for gas fixtures of the character described, which will be of simple but strong and durable construction requiring little or no attention, and having a minimum of moving parts to get out of order.

Numerous other objects and advantages of the present invention will become apparent as the description of the same proceeds and4 the invention will be best understood from a consideration of the following detailedv description taken in connection with the accompanying drawings forming a par-t of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

Figure 1 is a top plan view of the invention described.

Figure 2 is a side elevational view of the structure embodying the present invention.

Figure 3 is a section taken substantially upon the line 3-3 of Figure 1.

Figure 4 is a plan view of the main portion of the invention showing the same in one position assumed in the first part of the operative movement of the device.

Figure 5 is a transverse section taken substantially upon the line 5 5 of Figure 1.

Figure 6 is a section taken substantially upon the line (iL-6 of Figure 1.

Referring now to the drawings in detail wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates a portion of a gas manifold from which one 0r more gas fixtures of the type indicated by the numeral 2 are fed. The fixture 2 here shown is conventionally illustrated and symbolizes the usual gas range burner which has the feed pipe 3 leading thereto the outer end of which. pipe is bell shaped as indicated at 4, in the usual manner. A valve body indicated generally by the numeral 5 is tapped in the manifold body 1 having the coupling 6 leading therefrom and the handle 7 con trolling the usual plug body 8, the lower end of which projects beyond the valve body 5 as indicated at 9, which end or stem. 9 is surrounded by the spring 10 which normally acts to draw thev plug 8 into the valve body and thus maintain the same leak-proof. For use in connection with the structure embodying the present invention, the stem 9 has secured thereto the arm 11 which projects rearwardly at an angle with respect to the valve control handle 7. The oificeof this arm will be described more fully hereinafter.

Connected to the valve 5 by means of the coupling 6 is a gas supply line 12 which has the two branches 18 and 14, the branch 13 constituting the pilot supply pipe while the branch 14 extends into and terminates in the burner feed pipe bell 4 as clearly shown in Figure 1. The pilot light supply pipe 13, as shown in Figure 1 branches laterally intermediate its ends and has the free end portion 15 thereof arranged in a plane above the pipe 14 and substantially parallel therewith terminating substantialy midway between the burner .2 and the control valve 5, in the pilot tip 16.

Resting upon and extending longitudinally of the burner feed pipe 3 is a supporting block of generally elongated rectangular contour, indicated generally by numeral 17.

This block is provided at each end with the laterally projecting ears 18 each of which is provided with the depending portion 19 which extends downwardly on opposite sides of the pipe 3 as is clearly shown in Figures 3 and 5. Each of these depending portions 19 of the ears 18 has the longitudinally ei;- tending bore 2() formed in the lower end to receive the shanks of the screws 21 which pass through the clamp plates 22 and extends across the underside of the pipe 3 as shown.

At the rear of the block 17 is formed the laterally extending apertured bearing 23 through which the straight portion of the pilot pipe 13 extends, this pipe beingl clamped in position in the bearing 23' by the binding screw 24. The upper portion of the block 17 is formed to provide the tubularrhousing 25- the rear portion of which is internally threaded as at 26 to receive the tension nut 27. The forward portion of the housing body 25 snugly receives a pyrophoric pencil 28 against the rear end of which the tension nut 27 forces the spring 29 which is housed in the rear threaded pon tion of the housing, the forward end bearing against the rear end of the pencil while the rear end-thereof is pressed upon by the tension nut27 as clearly shown in Figure 6.

Upon theV forward end of the body 11 there is mounted in alignment with the housing 27, the ratchet wheel or striker 30 which as shown rotates about the vertical aXis of the pin 31. This ratchet 30 bears against the forward end of the pencil 28 which is in alignment transversely of the structure with the pilot tip 16 so that sparks struck from the pencil will pass the end of the pilot 'tip and ignite gas issuing therefrom.

Surrounding the upper end of the pivot pin 31 is a sleeve 32 which has extending therefrom an integral arm 33, the sleeve at the opposite side being provided with a longitudinally extending rib 34 for the purpose hereinafter to be pointed out. The sleeve 32 and the ratchet 30 are mounted to turn together in a clockwise direction only about the pin 31.

Pivotally att-ached as at 35 to the free end of the arm 33 is a dog 36 having the eX- tended portion 37 to the outer end of which is pivotally attached as at 38 one end of the pull link 39, the other end of this link eX- tending to a point adjacent the valve 5 where it is pivotally attached as at l() to the arm 11 which is mounted to rotate with the' valve plug 8.

Overlying the pilot tip or vnozzle 16 and the ratchet wheel and sleeves 3G and 82 is a cover plate l1 which is primarily intended to protect the mechanism from any substance which may be spilled over the gas burner 2.

A portion of the edge portion of the cover plate 31 is provided with a depending flange 42 to which is secured one end of the spring i3, the free end of this spring extending in wardly and having a groove 4A formed thereacross in which the rib 3ft of the sleeve 32 normally engages, preventing the sleeve from turning until suiiicient power is :tp-

'plied thereto to force the rib to slip out of the groove 14 in the spring.

The cover plate 41 has the pivot pin 31 passed therethrough and is thus held in position by this pin and in addition a securing screw 45 is passed through the plate at one side and `into the fork 46 formed from the side of the housing 25.

From the foregoing description it will be readily seen that when the gas valve handle 7 is turned the supply line will be half opened before the dog 36 swings to the position shown in Figure 4- where it engages the ratchet 30. Further turning of the valve handle 7' will swing the dog tlirough the niedium of the connecting links 39, and due to its engagement with the ratchet 30 will cause the arm 33 and the ratchet to turn also, the rib 3d breaking away from the spring 43 as will be readily understood thus causing the teeth of the ratchet wheel 3() to scrape across the pencil 28 and throw sparks across the point of the pilot tip 16 to ignite the gas issuing therefrom. 'lhe jet of llame which will be projected from the tip 16 will extend to the burner 2 and thus ignite the gas Howing therefrom and, as will be readily understood, if the gas burning at the burner 2 is accidently extinguished the pilot will continue to burn and will immediately relight the burner. The closing of the valve 5 will return the arm 33 and dog 36 to original position as shown in Figure 1 ready for further use.

I-Iaving thus described my invention what I claim is:

1. In combination, a gas burning element,

va valve for controlling the supply of gas to the element, a pyrophoric pencil arranged adjacent the element, a movably mounted striker associated with the pencil7 a link connected to the valve, a pivotally mounted arm, and a member pivoted between its ends to the arm and having one end arranged for movement into and out of engagement with the striker and the other end pivoted to the link.
