HENRY L. JOHNSON, OF VARNER, NEW HAMPSHIRE.

FIRE-KINDLER.

SPECIFICATION forming part of Letters Patent No. 511,433, dated December 26, r1893.

Application filed March 2l, 1893. Serial No. 467,042. (No model.)

v To all whom t may concern:

, full7 clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same. Y

My invention relates to improved devices for kindling fires by injecting a flame of gas mingled with air into the mass to be ignited and my invention consists in a novel combination and arrangement of parts all as herein' after described and claimed.

In the accompanying drawings is illustrated the simplest form of the device for general use in which- Figure l represents a Vertical section of an ordinary form of range showing the manner of applying the kindler. Fig. 2 is a longitudinal section of the most approved and simplest form of kindler. Fig. 3 is a transverse section of the same on the line .fr in Fig. 2.

The simplest form of device for practicing my method as before stated is illustrated in the accompanying drawings and consists of a hollow disk or head A which for` convenience in constructing the same has one end a made detachable or separate from the main portion and preferably in the form of a screw plug and which plug is provided withv a central screw threaded perforation a, with which a pipe B is engaged. This pipe B extends out some distance beyond the head with its end tapering or made into burner form with one or a series of escape outlets a2 therefrom, the opposite end being provided with a screw thread by which to couple the same with a supply pipe from a gas generator or other source. A pipe C of similar form is connected to the head and of such diameter as to leave a space between the walls of the pipes to form an air space or channel and which pipe C is also provided with an outlet orfoutlets similar to pipe B.

The head A is provided with a series of perforations b opening into the center thereof and the head is surrounded by a ring D provided with similar perfor-ations d.

A pin e projecting from the head engages an elongated slote formed in the ring the ply of air or regulating the amount supplied to the pipe 0.

The pipes B and C as above stated extend out some distance beyond the head A,? to form an elongated channel or air passage with the inlet openings for said air near the base thereof.

In applying the device aremovable door E is employed which is to be substituted for the draft door when the device is in operation and which door E is provided with an openin g which closely embraces the burner so that the entire draft supply to promote combustion shall be throughthe opening in the base of the burner and which door can be removed afterk the fire has been kindled; or, if foundv desirable, the ordinary draft door may be provided with a special opening having a door to close the same into which opening the burner can be inserted or a special opening may be made in any part of the range, stove, or other device to insert such burner, the location of which being such that the flame from the burner shall strike into the coal or otherv thing to be ignited or heated at the proper point. y

The device thus constructed is operated in the following manner: When coal or other combustible material is to be ignited the same is placed in the fire pot or grate; the gas is supplied to the burner which is ignited at the outlet or outlets in thel jpipe C, and the burner is inserted through the opening in the draft door and when the flame therefrom strikes the combustible material it causes the latter to become ignited.

By the form and construction of device herein shown the air to promote combustion, bothto the material to be consumed and also to the gas, enters at the base of the gas supply tube causing the same to be heated thereby before reaching the discharge outlet therefrom, and, being mingled withthe escaping gas in such heated state, tends to promote the ICO full combustion thereof and cause a moreintense heat to be injected into the combustible material to be ignited, the admission of the proper amount of air in accordance With the gas pressure being regulated by the ring D. By this method of heating or kindliug it will be seen that the only supply for promoting combustion ofthe fuel during the act of starting the fire is in the form ot a highly combustible Vapor or gas and that the same When ignited, coming in contact with the coal or other combustible material, serves first to ignite the same and, then, mingling with the fresh gases arising therefrom, acts on the other portions of the mass and serves in a short time to ignite fully the entire mass. It

will also be seen that no kindiing such as ordinarily employedis necessary and that a fire which has gone out by accident or otherwise may be relighted, Without the necessity of cleaning out or renewing the entire mass.

The device as will be seen is portable and may be carried from room to room and attached to the ordinary gas supply by a rubing, and a perforated air regulating ring surrounding the first named ring, the ends of the air and gas tubes being contracted, substantially as described.

In testimony whereof I have ailixed my signature iu presence of tWo Witnesses.
