INVEN OR ATTORN EY Patented Sept. 8, 1936 UNITED STATES PATENT OFFICE Application February 1 Claim.

This invention relates to igniters for gas burners and has for the primary object the provision of an electrical device operable from an electric house circuit and provides a safe, efficient and economical device which may be easily operated to ignite fuel of a burner and thereby eliminate the use of matches and the like.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation illustrating an igniter constructed in accordance with my invention.

Figure 2 is a top plan view illustrating the same.

Figure 3 is a vertical sectional view illustrating the device.

Figure 4 is a horizontal sectional view illustrating the device.

Figure 5 is a sectional view illustrating a handle supporting an electrode of the device.

Figure 6 is a diagrammatical view'illustrating the wiring diagram of the device.

Referring in detail to the drawings, the numeral l indicates a casing mounted adjacent a burner 2. A partition 3 is located in the casing for dividing the latter into compartments, one of which receives an electrical transformer 4 and the other receives an electrical coil 5 of the vibrator type. An electric circuit is employed between the coil 5, the transformer 4, and the burner 2 and has interposed therein spaced contacts 6 supported respectively by the partition 3 and the coil 5. The transformer 4 is connected to an elec- 40 trical extension cord'l having the usual plug 8 whereby the device may be connected into an electric house circuit, shown in Figure 2.

An igniter element 9 is electrically connected to the coil 5 by a conductor l0. The element 9 consists of an elongated cylindrical handle I I constructed of a suitable insulating material and is provided with a bore. Mounted in the bore and projecting beyond one end of the handle is an electrode l2. A chamber I3 is formed in the handle I l and communicative with the bore to receive one. end of the electrode which is shaped to form a terminal I4 detachably secured to the conductor H). A removable cap cover [5 closes 4, 1935, Serial No. 4,909

thechamber l3 and is apertured to receive the conductor In.

A circuit maker and breaker I6 is slidably supported by the casing and consists of a stem I! mounted for vertical movement with respect to the casing and carries at its lower end a contact head l8 adapted to bridge the contacts 6 when in its lowermost position. A rack 19 is secured to the upper end of the stem and has forked end portions to receive the igniter element,

' the weight of which lowers the stem H to disengage the contact |8 from the contacts 6 and thereby break the circuit between the transformer and the coil, rendering the igniter element inoperative. A coil spring 20 is mounted on the stem between the rack l9 and the casing acting to urge the stem ll upwardly to engage the contact l8 with the contacts 6 for completing the circuit between the transformer and the coil when the igniter element is removed from the rack.

To ignite fuel from the burner 2 the igniter element is removed from the rack and the electrode l2 brought into engagement with the burner causing a spark which ignites the fuel. The replacement of the igniter element on the rack ren-. ders the device inoperative.

Having described the invention, I claim:

A device for the purpose indicated comprising a casing having an interior division wall to divide it into compartments, a transformer disposed in one compartment, a spark coil disposed in the other compartment, the partition being terminated short of one wall of the casing and the spark coil having a contact overlapping the edge of the partition, 2. second contact carried by the partition in the same plane as the coil carried contact but spaced therefrom, an igniter element having a flexible conductor connecting it with the spark coil, and a combined igniter element rest and circuit maker and breaker comprising a rack for receiving the igniter element when not in use, a stem having a sliding mounting in the top wall of the casing, a contact carried at the lower end of the stem, and a compression spring surrounding the stem and bearing against the rack to elevate the latter and bring the stem carried contact into engagement with the first said contacts, the igniter element having a suificient weight when mounted on the rack to depress tne latter and disengage the stem carried contact from the other contacts.
