STOVE OR FU RNACE.

SPECIFICATION forming part of Letters Patent No. 505,448, dated September 26, 1893.

Application tiled December 5, 1892. Serial No. 464.033| (No model.)

.To all whom it may concern.-

Be it known that I, EDWARD FALns, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Stoves or Furnaces, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to improve the construction of the stove or furnace shown in my application for Letters Patent, Serial No. 437,934, filed June 25, 1892. In the stove or furnace therein shown vertical passages or flues were formed upon the inside of the rear wall of the re pot or chamber, and a smoke consuming chamber was located above the lire pot having a series of small passages communicating with and forming a continuation of the vertical passages or fines in the fire pot. The vertical passages in the re pot served as guide passages or lines for the flame, and products of combustion, conducting them to the small or contracted passages in the smoke consuming chamber, and as the entrances to said passages become filled or choked with the flame, the heavy unburned particles of the coal and unconsumed gases were burned. The vertical passages in the lire pot were in open communication at their lower ends with the ash pit, so that the currents or drafts of air were allowed to pass upward vertically at the rear side of the bed of coal, but l find in practice that for the production of the best results these openings should be closed so that all the drafts of air shall pass through the bed of coal, instead of at the rear side thereof, after which they may be guided upwardly to the smoke consuming chamber by means of the vertical guide passages. My present invention therefore consists in the combination of the lire pot or chamber, the rear wall of which has aseries of vertical ribs, to form guide passages or fines for the Haine and products of combustion, interposed partitions or equivalents at or near their lower ends, a smoke consuming chamber rising from saidfire pot above said guide passages or hues, and having a series of small passages communicating with and forming continuations of said guide passages or flues, as will be hereinafter set forth; also in other details of construction to be hereinafter pointed out.

Figure 1, shows in front elevation a heating apparatus embodying this invention, lthe front wall being broken away to expose the parts within; Fig. 2, a vertical section of the heating apparatus shown in Fig. l, taken on the dotted lines :c-ca Fig. 3 is a cross section on the dotted lines y-y Fig. 2.

The grate a herein shown as flat, and rectangular in shape, is provided at points midway between its ends with trunnions a', which rest in trunnion supports a2, formed integral with or attached to the back or rear wall b, and front wall b. The end walls b2, which when secu red to the front and rearwalls form a chamber herein denominated the tire pot have formed integral with or secured to them, at points opposite the ends of the grate, concaved portions, the curvatures of which correspond to the arc traversed by the ends of the grate when rocked or tilted on its trunnions.

A suitable top wall is provided for the lire pot or chamber and also an ash pit, which may be of any well known or suitable construction, and which may be provided with a door having a register or other suitable draft controller.

The inside of the rear wall b, is provided with a series of vertical parallel ribs c, extending preferably a short distance below the grate, when the latter yis in its normal or horizontal position, and said rear wall h, is herein shown as extending upwardly quite a distance above the top of the fire pot or cham ber to constitute the rear wall of the smoke consuming chamber, and the vertical ribs o, continue upwardly to a point near the top of said wall b. A plate c', is placed upon or against the ribso, forming the front Wall of the smoke consuming chamber, and the top, as well as the sides of said smoke consuming chamber will be closed in any suitable way, and from the top portion of the smoke consuming chamber above the upper ends of the ribs o, the smoke pipe leads. Partitions c2,

or any equivalents therefor, are interposed between the ribs c, near their lower ends, preferably on a line in the same plane with the grate when the latter is in its normal, or

horizontal position, said partitions thereby closing the passages` of spaces between the ribs c at the lower ends so as to prevent the currents or drafts of air which enter the ash pit from passing upwardly at the rear side of the bed of coal, but necessitating said currents or drafts of air passing upwardly.

and dividing it so that said ame ills orl chokes the entrances to said passages in the smoke consumlngchamber and there burns the uncousumed; gases orparticles which mayY beforced upwardly4 The high temperature at the entrances to these small'passages also assist materially in consuming the gases.

I findl in practice that by closing the lower` ends of thel guide passages, so that all cur,-

rents ordrafts of air shall pass up throughthe bed of coal,.muchbetter results are produced, thanif saidlower ends are open, be-

heated in their passage.

The grate a, has attached to its under side,l by means-of alink aiya rod or arm a4, pivoted at 0,5,.toa suitable stand, bracket or support,

or it may be otherwise supported, and the outer end of said pivoted arm or lever is socketed or otherwise formed to receive a detachable lever or shaker, which may be employed to move said arm or lever on its pivot to thereby shake the grate or dump the bed of coal.

If the heating apparatus herein described should be circular instead of rectangular the guide passages would be formed upon one Wall directly beneath the smoke consuming chamber.
