FIRE LIGHTER Filed Nov. 21, 1929 Patented Apr. 28, 1931 FIRE LIGHTER Application filed November 21, 1929. Serial No. 408,895.

This invention relates to a device for use in lighting fires, and more particularly to a device which is especially adapted for domestic use in lighting fires in stoves,

furnaces and the like.

An object of the invention is to provide a device which is very simple in construction and cheap to manufacture, and the construction of which is such as to preclude the possibility of cloggingthe jet openings in use and to insure air supply for maintaining the jets, the supply being such as to enhance the velocity of each jet. It is also an object to so construct the device as to ensure an eflicient mixture of air and gas, and to provide a device which may be inserted through a small opening and directly into the combustible fuel in the furnace.

With the above and other ends in view, the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawing, in which v Figure l is a transverse vertical section through a house furnace, illustrating, the manner in which the device embodying the present invention, may be used; 7

Fig. 2 is a side elevation of the device illustrative of an embodiment of the present invention; and

Fig. 3 is a transverse section substantially upon the line 38 of Figure 2.

As shown in Figure 2 of the accompanying drawing, the device embodying the present invention consists of a conductor pipe 1 of any desired length, which isprovided with a reduced end 3 for the attachment thereto of a hose 4 for conducting gas or other suitable ignitible fluid, into one end of the pipe, said end adjacent the end portion or nipple 8, being provided with a handle 5 to be grasped by the hand of the operator in manipulating the device. Upon the end of the pipe 1 opposite that provided with the handle 5, is a burner head which is indicated as a whole by the numeral 6. This burner head comprises a metal tube which is bent intermediate its ends as at 7 with the two legs or tubes 8 extending in screw threaded to engage the screw threaded end of the the hollow 12 are provided along the tubes 8, the openings in one tube being in staggered relation tothose in the other tube and all of the openings being formed in each tube at an angle to the transverse plane of the axis of pipe 1 which opens directly into coupling. Jet openings 11 and.

the tubes, the openings 11 in one tube being at such an angle that the gas escaping therethrough will be-projected across and laterally away from the other tube, and the openings '12 are at such an angle that they will project gas across the tube having the openings'll and between the jets issuing from said openings.

With this construction, the jets issuing from the openings in one tube will be projected angularly across the air space 9 between the tubes and in a like manner the jets issuing from the other tube will be projectedangularly across this air space in an opposite direction. This crossing of the flame jets across the space between the tubes causes a thorough admixture of the gases issuing from the jet openings and the air drawn through the space between the tubes, thus providing an efficient combustion.

If the head 6 is formed from a single tube bent upon itself, a device which is very cheap to'manufacture is secured, and this construction also provides a long narrow head which is entirely devoid of sharp angles so that in use, the device. may be inserted through the usual opening 13 in the front wall of the furnace 14 directly above the grates 15 and into the bed of fuel supported uponthese grates. Before such insertion, the gas will be turned on and lighted as it issues from the jet openings and then the device will be inserted into the fuel with the jet openings at the upper side. of the head so that the cross flames will be projected upwardly into direct contact with the fuel. As the device is inserted in the fuel bed, preferably adjacent the supporting grate, air will be drawn from beneath, the grate upwardly through the elongated opening 9 between the tubes, by the issuing of the gas through the jet openings across this air slot. This air flow through the slot 9 created by the projected flame jets, will clean this slot and as the parallel tubes 8 are circular in cross section, clogging of the jet openings when the device is inserted in the fuel bed, is effectually prevented. Insertion of the head into the fuel bed isfacilitated by the pointed shape of the forward end of the head, this pointed formation being the result of bending the tube abruptly and upon itself, thus partially ollapsing the tube transversely of the bend and thus forming a pointed end. An end is thus formed for the head connecting the parallel legs and to facilitate the insertion in the fuel bed, without expense other than bending the tube.

Obviously changes may be made in the construction and arrangement of parts, within the scope of the appended claims, without departing from the spirit of the invention, and we do not therefore wish to limit ourselves to the particular construction shown.

Having thus fully described our invention, what we claim is 1. A device of the character described including a continuous tube folded upon itself to provide a pointed end and formed with j et openings, and means for supplying a combustible fluid to said tube.

2. A device of the character described including a tube bent abruptl upon itself intermediate its ends to provic e a pointed end, with the end portions of the tube extended in parallel, closely spaced-apart relation and provided with a series of jet openings, and means for supplying a combustible fluid to said tube.

3. A device for the purpose set forth and including a head formed by asingle tube folded upon itself to partly collapse the tube at said bend and form a pointed end for the head, the end portions of said tube being extended in parallel relation with a narrow space therebetween and provided with a series of jet openings, a hollowcoupling connecting the ends of said tube, and means for supplying a combustible fluid to said coupling and head.

4. A device for the purpose described including a head formed from a single'tube bent upon itself intermediate its ends, said bend forming a pointed end for the head, the end portions of said tube being extended in parallel spaced apart relation and formed with jet openings, the openings in one tube portion being in staggered relationt o those
