DAVID KLINE, OF AKRON, OHIO, ASSIGNOR OF TWO-THIRDS TO AUGUSTUS D. POXVER AND EDYVARD A. STOUFFER, OF SAME PLACE.
OIL-BURNER FOR BOILERS, FURNACES, 80f).
SPECIFICATION forming part of Letters Patent No. 469,211, dated February 16, 1892. Application filed January 23, 1891. Serial No. 378.781. (No model.)
To all whom it may concern:
Be it known that I, DAVID KLINE, of Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Oil-Burners for Boilers, Furnaces, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
My invention relates to oil-burners for use in connection with furnaces for forging, brassmelting, and similar purposes; and it consists in certain novel features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.-
In the drawings, Figure 1 is an isometric view showing my feeder or burner as detached from the furnace; Fig. 2, the same with its top section lifted to show the interior construction of the upper chamber; Fig. 3, the same with the top and middle sections lifted to show the construction of the lower chamber. Fig. 4 is a plan View of my device with the upper section removed, showing the arrangement of the diverging directors and their relation with the oil-jet and air-blast. Fig. 5 shows my device in longitudinal vertical section taken through its central portion.
As illustrated in the drawings, my device is preferably constructed in three sections A,
B, and C, which when assembled and bolted together present substantially the appearance indicated in Figs. 1 and 5.
As shown in Fig. 5, the roof offered by the section A slants downward toward the mouth or outlet, affording a chamber above the section B, say, of an inch in height, and gradually diminishing toward the mouth until the space constituting the upper opening of the mouth-i. 6., the outlet between the sections A and B-is preferably, say, three thirty-seconds of an inch in dimension. I do not give these measurements as constituting a feature of my invention to which I propose 'to limit myself. I have in practice found these proportions to operate well; but in this respect my device may be varied without any departure from my invention.
Upon the upper face of the section B are fill or substantially fill the space between the floor and roof of the chamber between sections A and B and are made tapering to correspond with the longitudinal shape of said chamber. The arrangement of the ribs D E is such that the air as it is driven into the entrance G is made to evenly spread out into a fan-shaped body, and thus it escapes through the constricted mouth of the device into the furnace.
F is the oil-inlet, which is in any manner suitably connected with an oil-supply reservoir, and the oil is fed into the burner either by hydrostatic pressure or by means of a suitable pump.
Upon the under side of the section B are formed a number of divergingribs E, corresponding substantially with the ribs E, already described, and these ribs operate to evenly spread and distribute the air passing through the lower chamber of the feeder,which 7 5 is between the sections B and (Land which chamber, like that between A and B, tapers toward its mouth and has a restricted outlet. The oil is admitted only to the upper chamber, where it is caught by the airlast and sent forward into the furnace. No oil is admitted to the lower chamber, through which air only is passed.
The entrance end G is in any effective way connected with a suitable fan or blower for producing the required air-blast, and the oilsupply pipe should be provided with a valve or cook for properly regulating the amount of oil fed to the burner.
The operation is as follows: The air is re ceived at G, and, entering both the upper and lower chambers of the burner, is forced out through their constricted months into the furnace. The oil as it is fed into the upper chamber through the inlet F is instantly converted 5 into a spray, which, mingling with the air, is
spread out into a flat fanfshaped body and thus sent into the furnace and burned.
What I claim is- 1. An oil-burner comprising a series of fan- 10o shaped sections constructed to be secured together to form oil and air passages between them, these passages open at both ends, and an oil-supply pipe entering the oil-passage be- 5 tween its open ends, substantially as set forth.
2. An oil-burner comprising a series of fanshaped sections constructed to be secured together-,wherebyair and oil passages arefornied between them, an oil-supply pipe leading into 10 one chalnber, and ribs extending from the point where this pipe enters to the discharge end of the burner, substantially as set forth.
In testimony whereof I sign this specificaiion, in the presence of two Witnesses, this 20th day of December, 1890.
