HENRY WHITELEY, OF PHILADELPHIA, PENNSYLVANIA, AND JAMES MALLEN, OF NORTH EAST, MARYLAND,

OIL-FURNACE.

SPECIFICATION forming part of Letters Patent No. 538,854, dated May 7, 1895. Application filed December 1S, 1894- Serial'Nio. 532,145. (No model.)

To all whom t may concern:

Beit known that we, HENRY WHITELEY, residing in Philadelphia, county of Philadelphia, State of Pennsylvania, and JAMES MAL- LEN, residing in North East, iny the county of Cecil, State of Maryland, citizens of the' United States, have invented a certain new and useful Improvement in Oil-Furnaces, of which the following specification is a true and exact description, reference being had to the accompanying drawings, which form apart thereof.

Our invention relates to furnaces, andparticularly tov suchfurnaces as are employed to heat metal preparatory to subjecting it to forging processes.

The main object of our invention is to provide a furnace wherein a portion of the products of combustion Vmay conveniently be employed in one chamber to heat billets of metal and then be employed with vthe remainder of the hot gases to heat sheets or other forms of metal in a second chamber. Another object is to provide a floor on which sheets of metal can be supported in such a manner that they will be fully subjected to the action of the heated gases. y

To effect these ends our invention consists, first, in providing a furnace with certain chambers and passages for the heated gases, as will be more fully pointed out in the description and claims.

It further consists in providing pieces which support tiles or blocks so laid that spaces will be left between them, and in supporting on said piers, ridges, preferably consisting of scarfed bricks, on which the sheets of metal can be laid so that the heated gases can have free. passage around them.

Other novel features will be pointed out in the claims which are appended to and form a part of this specification.

Referring now to the accompanying drawings, which illustrate a furnace constructed according to our invention, Figure l is a sectional elevation of a furnace embodying our novel constructions and adapted to be heated by oil or gas burners. Fig. 2 is a plan view shown in section on the line 2 2 of Fig. 1; and Figs. 3, 4, and 5 are sections taken, respectively, on the lines 3 3, 4 4, and 5 5 of Fig. 1.

A is a furnace which is divided into a number of sections A A2 A3 by means of partitionsjD D2.

A is a heating chamber which is specially adaptedv for sheets of metal, and is provided with a oor C on which the sheets are supported. Any suitably constructed floorcan be employed in this chamber, and unless it is particularly mentioned we do not wish the claims to be limited to the particular door shown. We prefer, however, to employ the iioor shown which is built up as follows: Piers ce are built lengthwise of said chamber. On these piers are laid tiles or blocks e e in such a manner that spaces e2 e2 will be left between them and serve as .passages from the iues c. c"formed by the piers and the covering tiles to the space above the floor. The ends ofthe tiles which cover one flue do not, however, abut against the corresponding ends of the tiles covering the adjacent flues, but a space as c4 is left between them. In these spaces are arranged ridges e3 which are supported on the piers and which are preferably composed ot' a series of bricks as shown,it being noted that the bricks are firmly supported on the piers and are held in position by the adjacent'ends ofthe tiles e'.

In order that the sheets of metal which are to be heated in the chamber A maybe surrounded toas great extent as possible by the heated gases we prefer to make the supporting ridges with a narrow top. As shown the bricks are scarfed at e4.

E is a door conveniently placed in the end wall D of the furnace and H is an outlet flue situated above the level of the floor C and leading to a stack or outtake pipe H.

The heating gases are admitted to the chamber not only for the space beneath the Hoor but also through a passage f formed in the partition Dand opening nearorjust above the level of the floor as shown. This passage f leads from near the bottom of the chamber a2 which chamber constitutes the upper part of the section A2 of the furnace, which is divided into the chambers a2 c2 by the partition C2. This partition forms the floor of the chamber a2 and serves to support billets of metal which are placed in the chamber d2 to be heated. To support the floor C2 the piers e. e may be extended back as far as the partition D2 as shown. A passage f3 is formed 1n the partition D2 preferably near its top as shown, for theentrance of hot gases, and it will be noticed that by arranging the inlet passage f2 near the top of the chamber a3 and the oulet passage f near its base that the hot gases will flow downward through the chamber impinging directly on the billets placed therein.

E is a door arranged in the side wallof the furnace, by which access can be had to the chamber.

Any suitable furnace can be employed to furnish the necessary heat. XVe prefer, however, to employ gas or oil burners B B which may be arranged in front of or project through openings as d d iu the front wall D3 of the furnace. The section A3 into which the burners project is conveniently divided into two chambers a3 and c3 by a partition C3, the upper chambers a3 being connected with the chamber a2 by the passage f3 and the lower chamber c3 being connected with the space beneath the door C by means of the passage d d are airfiinlet openings in the WallD3. If desired a passagef3 can be provided in the iioor C2 so that some of the heated gases from the lower chamber c2 can flow into the lower part of the chamber a and assist in heating the billets of metal therein.

In operation the billets of metal are introduced into the chamber a3 through the door E and are subjected to the action of a part of the heated gases escaping from the section A3, which gases however, from` the arrangement of the chamber impingedirectly on the metal therein. When the billets of metal are properly heated they are of course removed and replaced by others.

The chamber A is especially adapted forv the heating of metal sheets which are introduced through the door E, and are subjected to the action of the heated gases, which not only enter through the opening f and flow along beneath the sheets but which also rise through the openings e3 e3 in the floor.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination in a furnace of a chainber a3 an inlet opening f2 for heated gases near the top of said chamber, a heating chamber A having a Hoor C provided with passages through it, and on which floor metal to be heated is adapted to be supported, a passagef leading from near the bottom of the chamber a3 into the chamber A at or just above the level of the floor C and dues or passages for conducting heated gases into the space beneath the perforated door.
