STOVE-G RATE.

SPECIFICATION forming part of Letters Patent No. 496,291, dated April 25, 1893. Application filed July 28, 1892. Serial No. 441,507. (No model.) Patented in England March 30, 1892, No. 6.180.

To all whom it may concern..-

Be it known that I, CHARLES TALMAGE BASTAND, a subject of the Queen of Great Britain, residing at 21 King Hcnrys Road, Regents Park, London, England, have invented new and useful Improvements Connected with D 0mestic Stove-Grates for Burning Anthracite Coal, (patentedin Great Britain, No. 6,180, March 30, 1892,) of which the following is a specification.

This invention relates to certain improvements connected with domestic stove grates for burning anthracite coal.

For the purpose of my invention 1 construct an ordinary form of open grate with a lower back grating or side gratings and Istop up the register part except to a slot or opening into the flue at a slight distance above a damper WhichI fit to close or to open the flue. The lower part of the flue terminates about level with the ash pit which has a door at the back. In first lighting the fire the damper is opened so that the smoke from the wood is drawn through the back or side lower gratings into the flue. As soon as the fuel is well alight I close the damper and allow the escaping gases, &c., to pass by the upper slot into the flue. The fire can be recharged with fuel as occasion requires without the damper being interfered with. A fire from anthracite 1cloal is almost incandescent and gives off great eat.

My invention will be understood by an examination of the annexed drawings.

Figure I. is afrontelevation of an open stove; Fig. II a section of same.

A is the fire basket with sloping front bars B and with open grate bars 0. O. at back to lead the products of combustion into the flue D.

E is a baifle or damper in flue D to regulate passage of products into chimney F or to shut off the communication when desired by the handle G and rod H.

I is a passage in upper part J of stove for gaseous vapor to flow from above the fire into the chimney F. I

J represents a valve within the ashpit K which valve can be opened for removal of ashes from the base of the flue D and also'for regulating a current of fresh air into the flue for reducing the heat of the fire and for checking the draft through the fire when necessary. L is a canopy over the front of the fire basket A for collecting the escaping vapors previous to their exit by the passageI.

M. M. are air holes in the front side cheeks N N of the stove and P P are other air holes in upper front of stove, the hind part of the stove being boxed in by the screen Q and forms an air heating chamber R.

The stove is preferably made in complete condition and to enable it to be set in the recess it is provided with rollers S for the purpose. The stove thus constructed is specially adapted for burning anthracite (smokeless) and other hard coal.

I find in practice that by placing pieces of anthracite coal of about the size of walnuts on the bottom grate to cover same and then some paper and dry wood upon said layer, then a second layer of coal, then some more paper and wood and then covering the same with coal to fill up the fire basket A I can obtain a rapidignition which in a short time will enable the damper E to be closed, so that all vapor escaping from the fire can pass through the channel I. From this moment the fire will continue to'burn, under slow combustion, for many hours, without the least attention.

Anthracite coal when properly burned and as is accomplished by my construction of stove gives off no smoke. It produces no cinders, but it has a dust residue which falls into the ashpit for after collection.

I may use a front screen to the ashpit for incl'osing the ashes and to prevent the fuel in the fire basket from falling out in front I form my bars 13.13. to slope downwardly in the basket.

WhatI claim, and desire to secure by Letters Patent, is

1. An open stove for burning anthracite coal, having a coal-basket inclosed by front, rear, and bottom grate-bars, the rear gratebars being intermediate between the coalbasket and a flue behind the same, an ash-pit beneath said coal-basket, adoor between said ash-pit and the bottom of the flue, a screen rising from the rear of the coal-basket and curving toward the front, an air-heating space or chamber, behind said screen, having air exits in the front flat wall of said chamber, a passage through the screen and air-heating chamber into the flue, a damper between said passage and the bottom of the flue to regulate the draft therein, and air-holes in the sides, or check pieces of the stove.

2. In an open stove forburningcoal,acoalbasket A, inclosed by front bars B inclined downwardly and rearwardly, rear bars 0, intermediate between said coal basket and a flue F behind the rear bars 0, a screen Q, curved from the top of the rear bars upward and forward and uniting, at its upper edge with a canopy L, an air-heating chamber B being inolosed by said screen and canopy, airexits I being formed in the latter, an ash-pit K beneath the coal-basket, a door .I' between said ash-pit and the bottom of the flue F, a dainperE in said flue between the coal-basket and passages I, between the upper part of the stove and the flue, and side-pieces, or cheeks N, N, provided with airholes M, substantially as described.

In witness whereof I have hereto signed my name, in the presence of two subscribing witnesses, this 4th day of July, 1802.

CHARLES TALMAGE BASTAND.
