GAS-LIGHTING DEVICE.

Application filed September 25, 1924. Serial No. 739,867.

To all whom it may concern:

Be it known that I, (humps P. PRICE, a citizen of the United States, residing at Boston. in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Gas-Lighting Devices, of which the following is a description, reference being bad to the accompanying drawing, and to the figures of reference marked thereon.

This invention relates to improvements in gas stoves, and more particularly concerns" the igniting apparatus utilized in such stoves.

One of the objects of this invention is to provide an igniting device which assures the ignition of all burner jets which are in operative condition.

Another object is to provide a simple igniting device which may be readily built into gas stoves having a burner pipe.

A further object is to provide an igniting device with an igniting aperture which device. a

With these and other objects in view as will appear hereafter in the accompanying drawing is shown one embodiment of the structure, in which:

Figure 1 is a longitudinal. section of a gas stove having an igniting device according to this invention;

Fig. 2 is a transverse section on line 2-2 of Fig. 1, showing theinterior of the gas stove with the igniting device in detail; Fig. 3 is an end view of a portion of one end wall of the stove, and

Fig. 4 is a perspective view of a part of the igniting trough.

The gas stove to which the present invention may be applied is shown as composed ofthe base 1 having mounted thereon a sheet metal "jacket 2. The front of the jacket has a door or other structure 4 to afioi'd access for air of combustion and to permit inspection of the burner while in operation. Near the bottom of this jacket 3. gas pipe 5 is disposed horizontally and longitudinally within the gas stove. This pipe is provided with a series of burner holes 6 in its upper surface.

In the end wall of the gas stove is located an aperture 7, opposite to but slightly above'the gas pipe 5. This aperture is norcentered with regard to the vertical plane through the gas pipe 5.

The U-shaped wire rocker 11 has the u standing end portions 10 formed at then: ends with eyes to be pivotally attached to the end walls of the jacket 2 by members 12. At the base of the upstanding portions 10. the rocker is formed with two oflisets 13.

The sheet metal trough 14 has a downwardly extending skirt 15. The horizontal portion of the trough 14 is extended beyond the end of the skirt l5 and is re-bent about the. ofl'sets 13. This construction assures a rigid relation of the trough 14 with the wire elements 10, 11, 13.

It will be noted that the pivot members 12 are located above the plane of the pivotal point 9. The offset relation of the pivotal point 9 tends to permit the door 8 to swing downward under the force of gravity after it has been released, and by its superior weight to move the trough 14 out of its operative position above the gas pipe 5 into the normal position in which it is not encountered by the hot gases from the flames above the burner holes 6.

One of the members 10 carries at a point intermediate its pivot member 12 and its oti'set member 18, a loop 16 which embraces the gudgeon 17 on the door 8, which assures a mechanical dependence of the movements of the door 8 and the rocker 11. A cotter pin 16 holds the loop 16 in position. This gudgeon 17 also serves as a stop member to-limit the movement of the door 8.

The method of operation of the structure is as follows: When it is desired to light the gas stove, the attendant opens the gas valve indicated at 18, to admit gas to the burner pipe 5. This gas issues through the openings 6 into the interior of the stove jacket 2. The attendant opens the door 8 by moving a projecting lug 19 formed integrally with the door 8 in a clockwise direction in Fig.

1, thus uncovering the aperture 7. The

ridge-shaped trough 14 and seek to escape at the ends of this trough. The attendant may now ignite the gases escaping at the end of the trough 14 nearest the aperture 7 by presenting a lighted match through the aperture 7. The mixture of gas and air under the trough l l'propagates the combustion along the line of the trough 14, and thus successively ignites the gas from the various burner holes 6. If any burner hole 6 is clogged, the combustion proceeding in trough 14 will continue to the next serviceable hole.

IVhen the attendant releases the lug 19 on the door 8, the weight of the door causes it to swing about its pivot 9 into its normal or closed position, and at the same time, the trough 14 is moved to a non-interfering position beyond the reach of the flames now proceeding from the burner holes 6.

It is obvious that changes may be made from the embodiment shown by way of eX- ample in the accompanying drawings, and I do not wish to limit myself within the scope of the appended claims.

Having thus described the invention, what I- claim as new and desire to secure by Letters Patent, is-- 1. In a gas stove, a gas pipe having a longitudinally alined series of burner holes, a jacket surrounding said gas pipe and having an aperture therein opposite said gas pipe, at door normally closing said aperture, a trough adapted to be swung into a position above said gas pipe, and pivoted means carrying said trough and operatively connected to said door.

2. In a gas stove, a gas pipe having a longitudinally alined series of burner holes, a

jacket surrounding said gas pipe and having an aperture ther in opposite said gas pipe, a rocker arm pivoted to said jacket, a toppivoted door supported by said jacket, a trough carried by said rocker, means connecting said door and said rocker to move said trough to a position above said gas pipe when the door is opened and to move said trough to a non-interfering position when said door is released.

In testimony whereof, I affix my signature.

CHARLES P. PRICE.
