OIL-BURNER.

Application filed July 12, 1919.

.l '0 all whom it may concern:

Be it known that I, CLARENCE A. Lown, a subject of the King of Great Britain, residing at Amherst, in the Province of Nova Scotia, Dominion of Canada, have invented a new and useful Oil-Burner, of which the following is a specification.

This invention has reference to oil burners, and its object is to provide a highly efiicient burner for liquid fuel, which burner comprises few parts and may be cheaply manufactured;

In commercial form the burner may be made up of pipe fittings and short lengths of pipe to constitute a twin burner so arranged that it will sustain Spreaders for the flames, thereby equalizing the distribution of heat, especially where the burner is installed in the fire box of a stove.

The construction of the invention is such that one or both members of the burner may be utilized at the same time and the structure may be placed in an ordinary stove fire box to take the place of a coal fire.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part 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 and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing Figure 1 is a perspective view of the burner ready for installation in the fire box of a stove.

Fig. 2 is a longitudinal section in a vertical plane of the burner shown in Fig. 1.

Referring to the drawing, there is shown a base 1 formed with a top cavity 2 to constitute a primingcup. Erected on the base at opposite ends thereof are posts 3, 4 re spectively. The post 3 includes a T coupling 5, and the post 4 includes a T coupling 6. Rising from the coupling 5 is a nipple in turn carrying a check valve 8 and the latter is connected by another nipple 9 through an elbow 10 to a pipe 11. Similarly the T 6 is connected at its upper end by a long nipple 12 through a check valve 13 and a short nipple 14 to an elbow 15, in turn connected Specification of Letters Patent.

to a pipe 16; The pipes 11 and 16 are of sufiiclent height above the base 1 to carry the pipes 11 and 16 above the top of the stove in which the burner is installed or to a sufficient heightso that the pipes 11 and 16 may extend horizontally out of the fire chamber where the pipe 11. is connected to a controlling valve 17 and the pipe 16 is connected to a controlling valve 18. The valve 17 is connected to an elbow 19 and the valve 18 is connected to a T coupling 20. Extending between the elbow 19 and the T 20 are long nipples 21, 22 respectively intermediately connected together by a union 23. The T coupling 20 on the side remote from the nipple 22 is designed to receive a supply pipe coming from a source of liquid fuel of suitable character.

The intermediate branch of the T coupling 5 is connected by an elbow 24 to a pipe 25 which, in the installed position, is horizontal and the pipe 25 is connected by an elbow 26, a short pipe section 27 and an elbow 28 to another pipe 29 situated immediately above the pan 2. The pipe 29 is closed at the end remote from the elbow 28 by a cap 30 and along the pipe 29 there are perforations 31, shown in the drawing as two in number.

In like manner the intermediate portion of the T 6 is connected by an elbow 32, pipe 33, another elbow 34, pipe 35, and a third elbow 36 to one end of the pipe 37 located immediately above and along the pan 2, the pipe 37 being closed at the other end by a cap 38. The pipe 37 is provided with perforations 39, like the perforations 31, the 28VTLl perforations serving as outlets for The pipes 27 and 35 flare with respect to one another, with the pipes 25 and 33 parallel but spaced by a distance considerably greater than the pipes 29 and 37, the latter being quite close together and parallel and within the width of the pan 2.

The pipes 25 and 33 serve as supports for flame spreaders 40 which may be formed of sheet metal strips of suflicient width with angularly bent ends 41 in substantial alinement and shaped to rest upon and be supported by the pipes 25 and 33 immediately over the matching perforations 31 and 39. In this manner flames issuing from the perforations 31 and 39 will strike the underfaces of the bodies of the spreaders 40 and be caused to spread in various directions, producing a distributed body of flame above the spreader, thereby causing intense heat over a large area, thus heating the portion of the stove above the fire box and, moreover, producing flame of sufiicient volume to travel about the oven or" the stove, where by the effect of the burner installed in the stove is similar to that of a burning bed of coal. In this respect the liquid fuel burner differs materially from other burners of like character, for experience has shown that the present burner is capable of producing oven cooking as well as lid cooking. Either or both of the associated burners may be used, being readily controllable separately by means of the valves 17 and 18.

In starting the burner, priming oil is placed in the pan 2 and preliminary heat obtained to vaporize the oil, and as soon as the burner is started it will continue in operation indefinitely.

What is claimed is 1. An oil burner comprising a base portion constituting a pan, posts rising from opposite ends thereof and formed of pipes, and burner members in the form of pipes extending from the posts in parallel spaced relation and then approaching each other and the pan, with the pipe portions adjacent to the pan parallel and in closer relation than the portions more distant from the pan, the pipe portions Where close together having perforations for the escape of fuel and lying Within the confines of the pan.

2. A-liquid fuel burner comprising a basic portion, posts rising therefrom, pipes carried by the posts in elevated relation to the pan and provided with continuations re-- turned upon themselves with the return portions perforated to form fuel jets, the return pipes having the portions with the jets close together and the portions where connected to the posts relatively Wide apart, and spreaders adapted to rest on the pipes Where Wide aparts and over the jets to vause Widening of the flames produced by the burner.

In testimony, that I claim the foregoing as my own, I have hereunto aifixed my signature.
