Leners Patent-N .105,385, alecm?, 12, 1ste.
IMPRQVEIVE-T IN' DUBLE-TWEER FORGE-TIRES.
The Schedule referred to in these Lettera P atent and making part of the same.
Be it known that we, GEORGE THOMAS and WIL-v LIAM W. MCLANAHAN, ofv Milesburg` inthe' "county of Centre and State of Pennsylvania, haveinvented a new and valuable Improvement in the Double-tweeil Forge-Fire; and we do hereby declare that the following is a full, clear, azul exact-` description of the construction and operation "of the same, reference being p had tothe annexed drawing, making a part of this J-specilica'tion', and to the letters and figures of referi ence marked thereoin' Y Figure 1 ofthe drawing is avertieal transverse section of our improved forge-fire.
Figure 2 is a vertical longitudinal central section ot' the same.
Our invention relates to; au improvementin the doubletweer forge-lire, for refining purposes, and consists in bending the.side-plates,belo\vthe tweer-iron,
, thereby enabling the tweers to be laid stationary, and Vin such positions that they will not `interfere with the manipulation of the loop for zniidation or other-purposes. v
i i The letter A of the drawing represents the oven or wall-plates of the lire.
In these walls are the semi'eireular openings l) b, for Ithe tweers c c, which are fixed in position.
Immediatelybelow, and forming the support for the tweer, is the side plateY B.
V'lhe lettere represents 'the bevel in'this plate, at `the upper part of the inside' thereof, theproportion of the slope usually being one and a half'iuch base to `-three inches in height or-depth. Thus, infa run of three inches, the plate is reduced from two and a half inches iii-'thickness to one inch, usually. i
g represents the bottombt the fire, which is made z .of z.' are ,the discharge-apertures for the einders, one on each side, at about the saine height, fand are centrally placed, but-lower down in the wall.
In the reduction and rening of iron,success de-v pende, in a large measure, upon the proper oxidation andother chemical reactions produced by the mechanical agency of the workman at the forge-fire.
Great skill and care are required in rthe operation7 and hence a forge-nre constructed in such a manner as to facilitate the manipulations, cannot fail to be of benefit. i
In a single-tweer forge-fire, on account of the blast being, in a measure, spent before'it reaches ,the oppositeside of the loop, it is usually found that this, the ;j1,ire-spirit side, is ot'inf'erior quality. In the old double-tweer lires, with perpclulicularsidcs,
the tweer-irons had Vto `be withdrawn whenever the loop was moved in the fire, thus involving machinery and time, besides unich fuel in reheating the loop.
In ou1forge-lire the cross-blast promotes the equal reduction of the loop. No part of it, if properly manipulated, will be of inferior quality' from want ot' blast. To facilitate the manipulation, and allow the workman to raise, expose, or withdraw the loop, without hindrance, we give thetweer 'a stationary position suiciently remoteto be out of the way of the loop.
` rlhus, by means bt' the beveled side-plates, we are enabledto derive all the advantages arising/from the `use of the perpeinlicular walls in double-tweer forgeires, without being obliged to remove the tweers every( time the loopis raised. At the same time, the bevel of' the plate presents no obstruction to the proper downward direction of the blast.
What we claim as our invention, and desire to secure by Letters Patent, is
1. lhe improved double-tweer forge-tire herein described, having a level bottom, g, and the side plates B beveled at c, as and for the purposes specified.
2. the perpendicular side plate B, beveled at its upper and inner corner c, substantially in the manner and for the purposes specified.
In vtestimony that we claim the above, we have hereuntosubscribcd our naines in the presence oftwo witnesses. Y
' his GEORGE THOMAS.
mark. W. W. MCLANAHAN.
