Letters Patent No. 95,291,1Zateel September 2S, 1869.

The Schedule referred to in these Letters Patent and making part cf the same.

To all whom it may concern:

Be it known that I, R. B. WAKEFIELD, of Springfield, in the county of Hampden, and State of Massachusetts, have invented a new and usefullmprovement in Braziers; and -Iv do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the said invention, and which said drawings constitute part of this speciication, and represent, in-

Figure 1, a plan view of' the same, with rim removed;

Figure 2 is a vertical transverse section'through line D E of ig.-1;

Figure 3 is a plan view ofthe rim; and

Figure 4 is a side view of the same, showing the curtain used to cover the draught-hole.

My invention relates to the braziers used for culinary purposes, and consists of a shell'orcase having a hole in the bottom for the passage of the smoke and gas, said shell having a grate, elevated a little distance from the bottom; and above the grate, and around the inside of' the shell, ,is placed iire-brick.

A curved back-beard extends upward andA backward behind the grate, and a hole is made in the side of the shell for the outward passage of the4 smoke and gas, when the bra'zier is used out of doors, and. a curtain upon the rim, which fits the top of the brazier, is used to open or close this aperture'.

That others skilled in the art may be able to make and use my invention, I will proceed to describe its construction, and the mode of its operation.

In the drawin'gs- A represents the cylinder or shell, the bottom of which has an aperture, d, therein, and the two ribs e are made upon the bottom, into or between which rests the back-boardc.

The projections n are also made upon the inside of the shell, near the ends of the ribs e, upon which projections n rests the grate C, which is made to extend from the front' partially across the bottom, or nearly to the hole d.

The back-board c is corrugated, to prevent its warping or bending out ofv its proper shape by the action of the heat, and it is bent back toward the hole m inA the back of the shell, as it extends upward, to assist in giving direction to the draught, and to make as much room as possible in the fire-box. This board is made of a proper length to pass into the shell endwise between the ribs e e, and when in its'place, is of a proper height to allowthe draught and smoke to pass from the fire-box, in front, over said board, and out at the opening made for that purpose.

A small portion'of'the shell is cut away at m, and the rim B is made to lit the top of the brazier properly, and a small curtain or projection, h, is made resting upon the projections or studs n, leaving a suitable space between the grate and the bottom of' the brazier, the fire-brick b, which are made to lit the shell properly, are placed with their lower edges resting upon the grate, and extending from the grate upward 4to. the top ofthe shell, and also extending around the inside of all that part'of the shell whichis in front of' the corrugated back-board. This construction and arrangement furnishes la fire-box which is not easily injured by the action 'of the heat, and in" which hard coal 'may be used with the greatest advantage.

A wire handle may be attached to the ears o, which are so secured to the shell that one end of the handleA shall be in front of' the lire-box, the handle standing at right angles to the direction of the back-board, when the brazier is suspended bythe handle. j By this arrangement the brazier is easily carried, `even when the fire-box is full of coal. v

A register'fhole, t', is made in the lower part of the shell, underneath the front part of' the grate, with a sliding dooroperating between two vertical ribs, or in any other proper and convenient manner.

Itis well knownthat there is greater economy in the' use of hard coal than in the use of charcoal, as the hard or anthracite coal retains its heat more perfectly and muck longer than soft coal, and this brazier is constructed with particular reference to its adaptation 'to the use of hard coal, although charcoal may be used therein. v The hole d may be of any form desirable, and if thc back-board were not corrugated nor curved, the brazier might still be operative; but I prefer to curve it for the sake of gaining room; and to assist in giving proper direction to the smoke and gas; and the corrugation is a Avaluable feature, inasmuch as it prevents warping.

The operation of my invention is as follows: 1f it is to be used within doors, one of the covers of the common cooking-stove, vor the lidv of any stove, is removed, and the brazier placed in the hole, the rim B being turned so that thecurtain h is just behindA the aperture mi., closing it. l

If a fire bekindled in the lire-box, thedraught of cold air enters the front register-hole i, passes up through the' grate and through the coal, over the backboard c, and down through the aperture Z,in`the bottom of the brazier, into the stove.

If it is desired to use it out of doors, it may be taken from the stove and carried out by the handle, and the rim B is turned so that the curtain leaves the aperture m open, and the smoke and gaswill pass out said ap' erture Vm, instead of the hole (l, which is closed by being placed upon the ground.

If it is desired to remove the ashes, the brazier is shaken from side to side. by means of the handle, and the ashes drop through the grate into the space below, and it may then be removed by holding the brazier in an inclined position, when the ashes will fall out through the register-hole i.

1t will thus be seen that this invention may be used in connection with any stove within doors, or it may be used upon the ground out of doors, with equal results in its operation; and it may be used with the hardest coal for fuel, as well as the softest wood or coal.

The several internal parts are all movable, so that if any one part becomes broken or burned out, it may readily he removed, and a new one inserted in its place.

The rib e may he single instead of double, extending to the top of the grate in height, and the upper corner next the grate be chamfered out, and the lower i corner of the grate next the rib c may be also chamfered out, so -that 4the grate may fit down to the rib nicely; and the grate may have two short projections or legs on'the lower side, one upon each side of and near the register-hole i, these legs being used to support the grate upon the front side, instead of the studs j or projections cast upon the shell, as hereinbefore men-- tioned; and the lower cornerof the front part of the grate, immediately around the register or draught-hole, is chamfered off, so that the damper may be made to slide within the shell instead of on the outside.

When the parts are being put together, the damper is rst placed within the shell, with the button, by which to operate it, protruding through the registerhole t', and the grate is then inserted in its place, and the back-board may have a small projection or lug at each end, upon the front side and at the lower edge, so that after it is inserted in its place, resting upon the rib e, the fire-bricks are then put in place, those at each end of the` back-board resting upon the said projections or lugs' upon the back-board', and thereby securing it firmly in place.

By this construction all the small projections upon the shell may be avoided, and the shell cast smooth, saving much labor and expense thereby.

I am aware that braziers for cooking-purposes have long been made and used; and I do not claim the same irrespective of my construction and arrangement; but having described my invention,

What I do claim as new, and desire to secure by Let-ters Patent, is-

A brazer, consisting of the shell A, having the openings t', d, and m' therein, and partially lined with the fire-brick b, or its equivalent, the grate G, backboard c, and themovahle rim B having the curtain h thereon, all constructed and operating substantially as herein described and set forth.
