OF LLANELLY, ENGLAND.
FURNACE FO R HEATING METAL SHEETS.
SPECIFICATION forming part of Letters Patent No. 576,734, dated February 9, 1897.
Application filed M y 15, 1896. Serial No. 591,719. (1% model.) Patented in England February 25, 1895, No. 4,015.
To all whom it may concern:
Be it known that we,THoMAs RICHARD LUD- FORD, of Cowell Street, SAMUEL REES DAVIES, of No. 17 Mansel Street, and REES DAVIES, of No. 31 Hicks Street, Llanelly, in the county of Oarmarthen, England, subjects of the Queen of the United Kingdom of Great Britain and Ireland, have invented certain new and useful Improvements in Furnaces for Heating Metal Sheets, (for which we have obtained a patent in Great Britain and Ireland, No. 4,015, dated February 25, 1895 and we do hereby declare that the following is a full, clear, and exact description of the invention, reference being made to the accompanying drawings, which are to be taken as part of this specification and read therewith, and one which will enable others skilled in the art to which it appertains to make and use the same.
Our invention relates to improvements in furnaces for heating metal sheets, and furnaces constructed according to it are espe: cially adapted for use in tin-plate and copper works, inasmuch as they are capable ofv heating the plates out of contact with coal or any other substance likely to cause dirty or waste plates. We provide for the flames and hot gases from the furnace being conducted lengthwise of the heating-chamber and under the floor of the same from back to front and delivered into the heating-chamber at the front end thereof and escaping into the chimney from the opposite or back end. This provision produces an equable temperature throughout the heating-chamber. Further, we use a series of grate-bars in place of the usual layer of coal or the like upon the floor of the heating-chamber.
The accompanying drawings show a preferred mode of carrying our said invention into effect.
Figure 1 represents a sectional side elevation of our improved furnace. Fig. 2 is a sectional plan taken on the line 2 2 of Fig. 1. Fig. 3 is a sectional front elevation taken on the line 3 3 of Fig. 1. Fig. 4 is a rear elevation of our improved furnace. Fig. 5 is a sectional plan taken on the line 5 5 of Fig. 1.
In the several figures, a designates the fireplace; b, the flue; c, theheating-chamber, and (Z the chimney. Accordingto the mode shown and is of the same construction, or nearly so,-
as heretofore. This fireplace opens into the flue b, which extends for the full area of the floor e of the heating-chamber c and immediately under it. At the front end of the said flue b there are three (more or less) vertical fiues f g h, leading'upward from it and opening into the heating-chamber 0. These vertical fiues are preferably within the heating-chamber walls and are in any case provided with independent dampers f g 71.. (See Figs. 1, 4, and 5.) The delivery-mouths of these fiues are set at different heights, so as to secure a uniform distribution of heat into the heating-chamber c. For instance, with three fiues the delivery-mouth of the middle flue f maybe in the plane of the floor e of the heating-chamber, while those of the outer fiues g h are in a plane parallel with the end of the heating-chamber and at about half the height thereof; The shaft 6 stands at the junction of the sloping roof j of the furnace with the arc-shaped back j of the heatingchamber 0. This back j serves also as the arched roof of the fireplace o.
A series of suitable flue-doors 70 Z m is provided for the purpose of giving access to the flue h under the heating-chamber c.
On the floor e of the heating-chamber 0 there are arranged, at suitable distances from each other, a number of transverse bearers or, adapted to support short bars 0, so as to constitute a kind of grate on which are laid the metal plates to be heated.
For starting the furnace and also for en ahling the products of combustion to pass into the chimney 01 without heating the heating-chamber c we establish a direct communication between the said fireplace and chimney by forming an aperture 19 in the downwardly-sloping roof j of the furnace, this aperture being controlled by a damper IVe retain the usual door q in the front end of the heating-chamber.
As shown in Figs. 1 and 2, a door at leads laterally from the combustion-chamber. As
shown also in said figures, partitions b b are arranged between the fiues b b.
We claim--- '1. In combination in a-furnace,the fireplace at the rear thereofithe heating-chamber above the fireplace, the fine 1) extending from the fireplace to the front, the central flue f extending from the flue L and opening in the plane of the floor of the heating-chamber and the fines g, h, on each side of the flue f, said flnes opening into the heatingcha1nber in a plane higher than the central fine f, each of said flues being controlled by a damper, substantially as described.
2. In combination, in a metal-heating furnace, a heating-chamber, the series of transverse bearers n on the floor of the heatingl 15 chamber and the series of sets of bars extend- 1 ing longitudinally of the furnace chamber, the bars of the several sets being placed end to end and raised by the transverse bearers from the floor of the furnace, substantially as described.
In Witness whereof we have hereunto affixed our signatures, in presence of two Witnesses, this 11th day of March, 1896.
