IMPROVEMENT IN APPARATUS FOR SMOKING MEATS.

Specification forming part of Letters Patent No. l 5,452, dated July 29, 1856.

To all rwhom 'it may concern:

Beit known that I, JOHN WRIGHll, of the city of Wilmington, in' the county of New Oastle and State of Delaware, have invented a new and Improved Mode ot' Smoking Meats, Fish, Ste.; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.v

The nature of .my invention consists in providing outside of the building used for smoking (A) furnaces with a grate and fireplate so formed as to cause all the smoke generated to pass into the house, and in setting up or building` inclined flues with smoke Stoppers and spreaders, so that the smoke generated will pass throughout the house, smoking the meat, Src., evenly in any part of the building, and in less time than is generally taken for such purposes, besides preventing dust or ashes from falling` upon the meat, &c., besides preventing re damaging the building or heating the meat. y

Io enable others skilled in th'e art to make and use my invention, I will proceed to describe its construction and operation.

In building the smoke-house A, I lay the foundation of` stone or brick two feet deep,

twelve inches thick, and nine feet square. I then run up the walls fteen feet high on the lowest or furnace side of the building, and on the highest or entrance side sixteen feet, giving the roof a pitch of about one foot in eight.

The walls may be of thethickness of eight or nine inches 5 but four and a half inches are thick enough for the smallest-sized buildings.

In running up my walls I set in a piece of three-by-four scantling, about nine feet from the floor ofthe building, on the inside, running across the front and back walls. I then set in a like piece about twelve inches from the iirst one, and others, until I get to the top of the lowest wall.

For smoking herring I use three or more pieces of the saine-sized scantling cut so as to slip between the walls, their ends resting upon the pieces c a a, c, built in the walls. I use like movable scantlings lled with hooks to hang meats, Src., upon. As to thel material for rooting, a shingle, board, or pebble root' will answer.

I v entilate the house by a door in the root' b, which 1n this sized house isV twelve by fifteen inches in size, which I open or close by means of a rod. By opening this door the smokepasses oft1 and sufficient light is admitted for all purposes.

In constructing the furnaces A A A, I pave with brick, about eight feet from the smokehouse, the whole length of the building. I make the furnaces about three feet high, with the end and division walls four and a half inches thick, (marked 1 l l l in the drawing 13;) the grates B B B twenty inches wide, twenty-eight inches deep; the doors of castiron, eleven by twelve inches. The whole length and breadth of the grate underneath the thick cast-iron or sheet-iron rests upon the walls and forms an air or smoke chamber, C, in size four by twenty-two inches, by which arrangement the draft is increased and all the smoke generated passes into theinclined hues D D D, and none is lost, as is often the case otherwise, when the contents of the furnace drop into the ash-chamber beneath the grate.

The inclined ilues in the first place connect with smoke-chamber C, passing through the wall of the house, and are eight inches square about six inches from the top of the pavement. I build the wall E across the building four and a half inches thick, leaving holes eight inches in diameter for sheet-iron collars eight inches in length. The flues D D D, which are composed of brick, earthenware, or iron, or other incombustible material, I lay after having packed in earth between the walls until I obtain the desired inclination. I then, provided -I build of brick, lay a header-course of brick upon the earth from the bottom of the entrance of the ue to the opening in the inner wall, E. The length of iues should be three-fourths the width of the house--in a houseA of this size, (about eight feet inside,) say lsix feet. I lay the rst course of brick without mortar,

.the course to be laid lengthwise against the row ofheaders also without niortar; then three other courses laid in mortar/'on each side ofthe first course of headers. The last course I draw over a little, so as to give the last course ot' headers a bearing of half an inch on each side, which forms the ilue. The brick flue is easier cleanedthan any other.

I leave an opening fourteen inches from the Wall, and build up with brick level With the pavement, and build a sheet-iron collar therein. I also make another upright iiue four and a half feet from the first, (the first marked F, the second G, in the drawing.) I then iill in and cover the flues with earth packed, and pave the top with brick, giving the pavement an ascent of about siX inches from the inner Wall to the Wall of the house. This pavement I lay even with the upright or vertical iiues or pipes F G.

The openings in the ues I stop With caps of sheet-iron when but little smoke is needed, and use the smoke-spreader, which will it any opening. This smoke-spreader, which is shown at or upon the vertical iiue G in the plan A, consists of a circular piece of tin or iron supported by wires attached to a rim made to fit the collars or openings, and is about twelve or fteen inches in diameter, and set about eighteen inches above the rim to which it is attached. This little spreader `:vill break the column of smoke arising and spread it all over the house.

My building, nine feet square, fifteen feet high, with these flues, will smoke ve thousand herrings in three days, at a cost of seventyve cents. These furnaces and flues can be erected or attached to any smoke-house already built, and the house not likely to take iire from the furnaces or sparks from the pipes, although the building be frame.
