Letters Patent No. 104,212, dated June 14, 1870.

GRATE AND FIRE-POT FOR HEATING-STOVES.

The Schedule referred to in these Letters Patent and making paxt of the same.

I, PHILIP JACOB ScHorr, ofLousville, in the' county of J eiiersou, State of Kentucky, have invented a certain Improvement' in Heating-Stoves, of which the following is a specification.

The first part' of lmy invention relates to the better support and easier movement of grates placed in Stoves. lhe second part of my invention relates to the combination, with tbegrate, of `a perforated conical or cylimhical-shaped receptacle or fire-pot, for c oal used as fuel.

rlhe third part of my invention relates4 to thc combination of a perforated conical 'or cylindrical-shaped tube with the grate.

The object of my improvements is First, to effect a better support of the grate, and

at the same time an easier movement, unobstructed. by particles of fuel fallingthrough the bars of the grate. s

Second, to isolate the burning fuel, to some extent, from the outer wall of the stove, and prevent that wall becoming over-heated and red hot by circulation of ail between it and the fire-pot containing the burning fuel.

rlhird, to admit abundance of atmospheric air to alll regulated by dampcrs on the outer wall of the stove.

Fourth, to prevent the escape'of the poisonous carbonic-oxide gas through the side' walls of iron stoves into the room.

By the experiments of MM. Deville and Traost, French chemists, and General Morin, of the French Academy ofScicnce, the permeability of iron heated to a high degree, by gases, has been proved conclusively.

rlheformation of this dangerous gas is caused by imperfect combustion and the want of oxygen contained in atmospheric air.

By my invention abundant air, already heat-ed by coming in contact with radiating iron, is conducted to the burning coal, and, by isolating thetire-place from the outer wall, and causing a free circulation around it, the obnoxious gas, even when formed, will be carried off through the ventilating pipe before penetrating through thc'side wallsof the stove.

With a litt-le care the draught can be so regulated by dampers as to prevent the outer wall of the stove from getting red hot, and allow the escape of the gas.

Description of the'Accoiiipmiying Drau/'tulp v'Figure 1 is a plan of the invention.

is a vertical transverse section ou line General Description.

A is the base of a stove, with four brackets, B, act` ing as a 'support to the lire-pot C.

.lo reduce'friction, these brackets arerounded on their upper surface; they are provided with a guard, b, also rounded. 4

`Ou these brackets -rests the i'e-potlU, perforated with numerous small holes, round or square, and provided around the entire circle with a depending flange, a, fitting to the guards of the brackets br.

The tirepot C is also provided inside with a flange, c, to receive the grate proper D, and outside with a perforated flaugel, to produce more-heating surface for passing atmospheric air to be forewarmed before entering the place of combustion.

This ange is also intended to form a protection to the bracket and the guards attached to it, and prevent fuel falling through the grate-bars from lodging upon it.

By means of the runner a., the fire-pot and grate-v attached to it may be turned around the entire circle, every part reached and cleaned.

Flange c is provided with three orinore sockets, to receive and hold in its place cue-half part'of the grate D.

Upon the lower side of 'the outer ring of the grate, conical-formed -projections-.are cast, correspomling with the size of the sockets in which theyare to tit.

The grate D, of the usual construction, with plain parallel bars, is divided into two parts. Ouepart rests on fiange c iu sockets.

o this part the cone E is attached either' permanently, forming one'easting with the bars, or attached to a half circle with slits to receive the project-ions or -tenons provided for at the base ofcone E, and h'eld in its place.

'lhis half circle is part of .the center. bar ofthe grate, and is also connected with the parallel bars vertical to the center bar.

The cone E is hollow, and perforated with holes to admit air into the. very center of the burning coal.

In stoves with small tire-places the cone may be omitted. -In large tire-places. the number may be increased.'

The other half of the structiomwith parallel bars, and Aarranged 'to open downward, to remove ashes and ciuders when 4neces-v sary.

lire-grate is of the usualv con.- Y

F is the outer wall 01 shell of the stove. It sits back from the fire-place luxeuough to admit the escape of gases formed and penetrating through the holes :md sido wall ofthe fire-pot.'

A C'Zn.

I claim as my inventiou- The combnzxtionof the r-.pot C with the depend-V ing auge a, anges c and d, grate D, cone E, base A, and brackets B, substantially as and for the purpose hreinbefore set forth.
