BURNER-BLOCK AS APPLICABLE TO FURNACES.

Specification of Letters Patent.

ra'fiented March 26, 1907.

Application filed September 20,1906. Serial No. 335,372.

To (til whom it may concern:

Be it known that we, ISAAC H. BACON and Nine NELSON, citizens of the United States, residing at the city of Salem, in the county of Salem and State of New Jersey, have invented certain new and useful Improvements in Burner-Blocks as Applicable to Furnaces, of which the following is a specification.

Our invention relates to an improvement in burner-blocks as applicable to furnaces where oil is used as a fuel; and the object is to provide a block so constructed that a more or less perfect combustion is obtained, thereby producing a greater degree of heat in proportion to the consumption of fuel as compared with devices of this character now in use.

With the foregoing object in view our invention consists in certain novel features of construction and combination of parts, which will be hereinafter pointed out, and de scribed in the claims.

In the accompanying drawings, Figure 1 is an end view of the burner-block. Fig. 2 is a top plan view. Fig. 3 is a vertical end view, and Fig. 4 is a vertical sectional view.

A represents the burner-block. The block is made of any suitable material, but preferably of cast-iron.

1 is an opening through which the heat passes into the furnace. (Not shown.)

2 is an opening located directly opposite the burner 3.

4 is the combustion-chamber.

5 is an air-flue passing, preferably, through the side of the chamber.

6 is a partition formed by the continuation of one side of the air-flue, as indicated by the dotted lines.

This partition is, however, not essential, but is made thus to avoid the sharp corners wherein the air could collect and to a certain extent produce a back draft.

7 is a baffle-plate which is disposed between the restricted aperture 2 and the airintake and inclined from the rear of the chamber toward the side of the air-intake, extending, preferably, to a point beyond the mouth thereof.

8 is a pipe leading from the source of'the fuel supply (not shown) and having its burner end 3 in alinement with but preferably disposed in such relation to the aperture 2 as to cause the fuel entering the chamber to entrain air with it. The bafiie-plate 7 is most desirably formed as the bottom inclined wall of a laterally-inclosed bafile member having side walls 8, which flareto the side walls of the chamber at an angle considerably greater than the inclination of the baflie-plate proper, 7.

B in Figs. 1 and 3 designates the front end of the block.

Our device is operative as follows: The block A is fitted under the cap of a furnace, the fuelsupply which is under pressure is ignited at the point of burner 3, which drives the ignited fuel and air through the opening 2 into the combustion-chamber 4, meeting in the combustion-chamber A the air which flows through the air-flue 5, where the combustion takes place, and the flame and heat is carried through the opening 1 into the furnace, (not shown,) to which the block is connected. By the means of the partition 6 the air is directed into the combustion-chamber. This partition may, however, be dispensed with, as the same results may be had by the use of the baffle-plate 7, as the back draft caused by the sharp corners formed by the wall of the block A and the bafiie-plate 7 are so trivial as to be of little or no consequence as affecting the effectiveness of the device. The bafiieaplate 7 is so arranged as to prevent the flow of oil or flame from the burner striking down into the air-flue beneath the burner-block, in that it extends within the block beyond a point where the flue enters. Also by being thus constructed the flow of air through the opening 5 does not meet the fuel from the burner 3 until said flow has opened into a spray, which occurs a little distance from the mouth of the burner. The air flowing through the flue 5 and being directed byithe partition 6 flows into the combustion-chamber 4, uniting with the oil after it has sprayed, and by this method of uniting a more perfect combustion is produced.

Slight changes might be resorted to in the form and arrangement of the several parts herein described without departing from the spirit and scope of our invention. Hence We do not desire to limit ourselves to the exact construction as herein set forth; but,

Having fully describedljl our invention, what we claim as new, andidesire to secure by Letters Patent, is

1. In a burner-block, the combination of a chamber open at its front, means for delivering fuel and air through the rear of said chamber toward the front thereof, an alr-intake opening upward through the floor of the chamber, and a baffle-plate extending from the rear of the chamber beneath said delivery means downward and forward over said airintake.

2. In a burner-block, the combination of a rectangular chamber open at its front end and provided with an aperture in its rear end and an air-intake through the rear of its floor, and otherwise imperforate, a fuel-duct exterior to the chamben terminating adj acent but not filling said aperture so as to deliver fuel and entrained air therethrough, and a bafHe-plate extending from the rear of the chamber beneath said aperture downward and forward over said air-intake.

3. In a burner-block, the combination of a chamber open at its front end and provided with an aperture in its rear end and an air-intake through the rear of its floor, a fuel-duct exterior to the chamber terminating adjacent but not filling said aperture so as to deliver fuel and entrained air therethrough, and a baffle member extending forward from the rear Wall of the chamber in alinement With said aperture and having side Walls flaring laterally substantially to the side take opening upward through the floor of the chamber, a baflie-plate extending from the rear wall of the chamber beneath said delivery means downward and forward over said air-intake, and a second baffle-plate extending upward and. forward from in rear of said iritake into proximity with said other baffleate.

p In testimony whereof We affix our signatures in presence of two witnesses.
