FUEL IGNITER. Y,

. Application filed January This invention relates to devices for igniting fuel in furnaces, cook stoves and other heaters of this character, the general object of the invention being to provide means whereby a blast of gas may be projected against a mass of fuel resting upon the grate of the furnace or sto-ve to ignite the same.

More specifically one of the objects of this invention is to provide a pilot light pipe extending through one Wall of the stove or furon the grate and provide a deflector or baffle which be shifted into a fully open or a fully closed position and which will direct the iame projected lfromv the pilot pipe either downward against the coal or permit the flame to be projected directly outward against the upper portion of the fuel.

A further object is to provide a construction of this character in which the pilot pipe is disposed above the grate and sufficiently so as to prevent the mouth of the pilot pipe bein closed by ashes, cinders or the like.

y invention is illustrated in the accompanying drawings wherein F1 re 1 is a vertical sectional view through a cook stove showing my invention ap lied thereto;

igure 2 is a vertical sectional view throu h the side wall of the stove showing the pi ot pipe and the deiiector in elevation;

Figure 3 is a horizontal section, the pilot pipe and deflector being shown in plan;

Figure 4 is a perspective view of the end of the pilot pipe and the deflector; and

lFi re 5 1s a front elevation of the plate whic supports the pilot pipe and which is attached to the wall of the stove.

'In Figure 1 I have illustrated my invention as applied to an ordinary cook stove having the usual grate 10. It will be understood that my invention maybe applied to anyv form of stove or to any form of furnace. Through the rear wall 11 of the stove there is disposed avpilot pipe 12. This pipe extends through the annular boss 13 of the plate. 14, which is bolted, riveted or otherwise attached to the wall of the stove. This plate is formed with a key'hole slot 15 and, of course, the wall of the stove is to be formed with a' slot 16 immediately behind 'this key hole slot.

The pilot pipe 12 is provided with a valve 17 whereby the gas discharged throu h this -pipe may be controlled. Attached to t e for- Ward end of the pilot pipe is a hinge, desig- 2, 1926. Serial No. 78,920.

ligure or to an intermediate position. The

spring 20 engages this baffle plate to swing it downward, the rear end of this spring extending over the pilot pipe. A chain 21 is attached to the baffle plate and extends downward through the apertures 16 through the key hole slot 15. The spring acts to force the baffle plate downward and by pulling upon the chain the balie plate may be raised to any desired extent, the links of the chain bein engaged in the contracted portion of the ey hole slot 15 in order to hold the chain from being pulled out.

It will be particularly noted that :the pipe 12 is disposed above the general level' of the coal on the grate 10 and discharges a blast of ignited gas against the coal. By placing this pipe above the level of the coal there will be no chance for ashes, cinders or the like to plug up or close the discharge end of the pilot pipe. This ig-niting device takes the place of paper or kindling for igniting coal or other fuel and, of course, after the fire is started the gas is shut ofi1 by means of the valve 17 While the igniter is shown as attached to the rear of .a range or cook sto-ve, it is understood that it may be applied to the front or side or, in fact, in any convenient place. This device may also be used-as a permanent feature for igniting furnaces either singly or in series.l It may also be used on either vside 'of an open fire place and this permits it to be attached to any existing range or obviously, the device may form part of the permanent attachments of stoves or ranges.

I claim z- 1. The combination with a heater, of a gas pipe permanently mounted on the heater and extending into the heater above the grate thereof and adapted to discharge a blast of ignited gas against a mass of fuel, a delector hin edly mounted upon the inner end of sai blast pipe, and means disposed exteriorly to the heater for shifting the deiiector into various angular relations to the blast ipe.

2. The com ination with a heater, of a gas pipe permanently mounted on the heater and extending into the heater above the meagre rate thereof and adapted to discharge a 4.
