IMPROVEMENT IN APPARATUS FOR THE MANUFACTURE OF LAMP-BLACK.

Specification forming part of Letters Patent No. 222,337, dated December 2, 1879;

l March 5, 1879.

To all whom itmay concern:

Be it knownthat I, HENRY B. WINSLow, of Marblehead, in the county of Essex and State of Massachusetts, have invented a new and Improved Apparatus for the Burning of Oil in the Manufacture of Lamp -Black, of which the following is aspecification.

My invention relates to a furnace for burning oil' for the production of lamp-black; and consists in a certainnovel construction, Whereby the use of water is dispensed with and the character of the production improved.

My furnace is shown in the accompanying drawings, wherein- Figure l is a vertical longitudinal section. Fig. 2 is a front elevation, partially in section.

Similar letters of reference indicate corre- I prefer to build the furnace Adouble, as shown. It is to be built of brick lined with fire-brick, with-a rear wall, a, that divides the furnace-room from the condensing-room, side walls, b b, front 0, and central dividingwall, d,

- that divides the furnace into two long and r narrow fire-spaces, e e.

The bottom of the fire-spaces e is formed by a sheet-iron plate, f, that is supported by the walls, and the space 6 below plate f serves as an air-space through which ,air may circulate by openings 9 in the front and sidewalls, this circulation of air tending to keep the plate f cool.

The rear of the fire-space 6 extends upward and communicates by an openingflt, through the wall with the condensing-room. In the front wall, 0, there is an opening to each 'firespace 0, and a door, 1', to each opening.

The oil or other liquid is to be suppliedby pipes 70, that enter from the outside near the rear of the fire-spaces. The outer end of each by the doors.

application filed pipe is is fitted with a cup-shaped receptacle, Z, into which the oil will run from the vertical branch of the main supply-pipe m, so that the amount of oil running into eachpipe k may be observed and regulated by a cook. The pipe m will supply the oil to one or more furnaces and the supply of material to each furnace will be separately regulated.

No burners are employed, but I prefer to place in the fire-spaces beneath pipes 70 shallow cast-iron drip-pans o to receive the oil, and the oil running in faster than it will burn will drop while on fire to the pans 0; and be spattered into small particles. These pans are to be changed frequently, access to. them being obtained by doors 2'.

p is a slide andi a door, both of which close air-tight, while by opening the slide more or less the ingress of air may be regulated.

By constructing the fire space 0 long and narrow the plate f is more readily kept cool, and the space in'front of the pointofcombustion renders the smoke less liable to escape The products of combustion pass through the opening it to the condensing-room, which will be lathed and plastered, and if the room is sufficiently large a number of furnaces, A, may be fitted to discharge into the same room.

Having thus described my invention, I claim as new and desire to secure by Letters, Patent-- I l I A lamp-black furnace having walls-a. b c d, with openings g, spaces e e separated bymetallic plate f, and oil-suppl y pipes, all arranged as shown and described.
