Specification of Letters Patent.

Patented April '7, 1908.

Application `tiled November 9, 1907. Serial No. 401,409.

T o all whom 'iff/nay concern: Beit known that i, FRANK R. BIGLER, a

`citizen of the United States, residing at Kansas City, inthe ,county of Jackson and State of Missouri, have invented certain new and useful lm rovements inHeat-Deflectors; and I do dec are the following to be`a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to heat deectors, and more particularly to a device of that class for use in stoves and furnaces adapted for yburning fuel gas; the object of my invention being to provide a deiiector with which a substantially perfect combustion may be secured, and by which the heat from the burning fuel is so directed as to secure the greatest eiiiciency therefrom.

A further object is to provide the improved details of structure which i will presently describe and claim, the same being illustrated in the accompanying drawings, in

Referring more in detail to the parts 1 designates the fire pot and 2 the outer casing of an ordinary hot air furnace; the former being provided with the customary flue 3 and heat coil openings 4, and the latter being provided with the air pipes 5, which lead to the apartments to be heated.

in the fire pot l is the grate-6, and in the casing, below the grate, is the ash door' 7.

Entering the furnace; through casing 2 or door 7, as may be desired, is the fuel supply pipe 8, which extends upwardly through ygrate 6 and is connected with the perforated burner coils9by a Y union 10 said coils being suitably supported in the i'ire pot and preferably comprising rings of dierent diameter, set 'one above the other.

. Supported on grate 6 is a heat deiiector,

preferably made up of individual pieces 11, having narrow, curved base portions 12, vadapted to seat in a circle near the center of the grate, and having the flaring end portions' 13, which extend over the burner coils 9 to the inner surface of the fire pot, with which they contact; the outer end of each piece 11 being provided with a recess 14, through which the smoke and fumes from the burners may rise.

ln assembling the arts, the burner coils are set in substantial y the position shown, these coils being preferably two in number and formed in circles, although the number of coils may be varied to meet dierent requirements, and the contour of 4the burners varied according to the style of the furnace. After beingset, the coils are connected with the supply pipe by any suitable union, the Y construction shown being preferable where one coil is set above and to one side of the other.

`When the burners have been installed, the deliector is set in place thereover, so that the heat rising from the burners, when the furnace is in operation, will rise against its under surface and be conducted u wardly and outwardly, to contact with the fire pot, from which the heat is radiated to the chamber between the fire pot and casing, and from thence is conducted through pipes 5 to the apartments.

By having a covering over the burners, the air coming in throug/hthe burners and grate openings is carried upwardly to the periphery of 4the deflector, andl then passes upwardly through the deflector recesses 14 to the top of the fire pot, where the smoke and fumes pass out through the flue.

By placin one of the burner'coils slightly over the ot er, .the heat, rising from the lower coil, will heat the upper, and the gas from the upper coil is delivered in a highly combustible condition; and by inclosing the coils, the fuel particles are spread when they contact with the deflector and a'substantially perfect combustion secured.

Vhile l have described the deflector as being formed in sections, it may be in a single piece, if desired, with the'recesses 14 cut from its peri hery; the sectionalconstruction being re erable however, owing to the greater fac` ity with which it may be installed; and while l prefer to construct the deflector of iire clay, it may be of cast or sheet metal, if desired.

While I have described my s to the deflector described, which may be used in combination with any stove or furnace, and particularly to those adapted for burnin fuel gas.

aving thus described m invention, what I claim as new therein and esire to secure by Letters Patent is 1. A de'lector unit comprising a body member that is narrow at one end and flares toward the other end, the flared end of said member being provided with a recess and the narrow end wlth a curved leg portion, subo stantially as and for the purpose set forth.

2. The combination with a suitable lire pot, and a defiector located in said fire pot over said burner, said deiiector comprising individual units having flared outer ends resting against the iire pot and narrow inner ends terminating in downwardly curved le s which support said units at the center of sald grate, the iared ends of said units being recessed, substantially as and for the purpose set forth. y

In testimony whereof I alix my signature in presence of two witnesses. FRANK R. BIGLER. Witnesses:
