IMPROVEMENT m PORTABLE FoR'eEs.

.1315 Schedule referred to in these Letters Patent and making part of the heme.

To all whom it may concern.-

Be it known that we, PHILANDER. H.1toors and FRANCIS ILL-ROOTS, of Oonner-sville, iii the county of ,Fayette and State of Indiana, have invented certain Improvements in Portable'l orges, of which the following is a specification, reference being bad to the accompanying drawing. 7 Our invention relates to portable forges,and consists lll constructing and arranging in a novel, compact, convenient, and portable shape, a fire-bed, with its hearth and chimney, a blower, with a suitable device for opcrating it, and with tuyere connecting it to the fire-bed,

.a' coal-bod, slackrtub, 8w, all as hereinafter described.

In the drawing- Figure 1 is a side elevation, partly in sect-ion, to show the arrangement of the firebed;

Figure 2 is a longitudinal vertical section of the blower; and

Figure 3 is a vertical section'of a cap for the blower, that may be used in place of a valve.

Figures 4and5 are views of parts detached.

Our forge is constructed entirely of metal, and of any size that may be desired. 7

We make a frame of two front uprights, A, and two rear uprights, O, with a shelf or platform, D, extending between and connecting them near their lower ends, as

clearly shown in fig. 1, and with the hearth E of the forge extended so as to rest upon and be attached to the upper ends of these posts, as shown in the same figure.

The front uprights A are solidly conuectedtoa crosspiece, b, on the ends of which wheels B'arc placed.

The rear uprights O are also connected in like mannerto a cross-piece, a, the ends of which are turned down so as to't'orm feet for the rear end of the forge to rest upon. 4

Around the hearth E, which is made oblong, with round corners, or in any other form desired, a raised guard or rail,-I may be placed for the purpose of confining loose coal, ora'ny other article placed thereon.

Near the fi'ont end of the hearth E, in an opening suitable for the purpose, is placed a fire-bed, P, made in the form of a concave recess, with its walls curved, and with its bottom provided with perforations opening into a vertical passage, 0, having a pivoted valve-gate,f,

the same purpose gates dare pivoted on the sides ot'the hearth, to be turned up out of the way, as shown in Over the front end of the hearth'E ismounted a chimney, K, with smoke-stack It,'forcarrying on" the smoke from the forge.

On the platformD is placed a blower, H; to be socure, it may be bolted thereon.

From this blower itsv air-pipe, G, rises first vertically, and then at the proper height bendsat right angle'sand enters'the vertical pipe 0 just under the bottom of the fire-bed, so that all ashes or other material that drops from the fire-bed will pass by the open end of the induction-pipe fromthe blower, so as not to obstruct or interfere with the tuyere-blast.

The blower is operated by a belt,I, which passes over a driving-wheel, J, mounted on an arm, 9, ,attached to' the chimney K, or in any other suit-able manner, as shown in fig. 1.

As gasfrequentlyfinds its way into the blower when the forge is not being used, a method for its escape'is provided by means of a lift valve,- 0, arranged upon the blower, as shown in fig. 2.

In place of this lift valve an ordinary cap, .9, as shown in fig. 3, may be used. In the use'ofeither, it

will be seen that should an explosion of gas take place,

orshould the pressure of air become very great, the liftvalve will be raised or the cap blown off; but, in order to prevent the gas generated by the burning coal in the tuyere from entering or being drawn into the blower by any accidental turning of the blower inthe wrong direction, we attach a small ratchet-wheel, R, and

pawl S, to the hub of the driving-wheel, as shown in figs. 4 and 5, It is obvious that the same devices may be applied to either of the shafts of the abutmeuts, instead of to the hub of the driving-wheel for the same purpose.

- On the same platform with the blower is placed so curely a slack-tub, M, and loosely a coal-hod, N, as

shown in said fig. 1.

To the rear sides of the uprights G are pivoted a pair of arms, L, so arranged that they maybe .usedin lifting the feet on the rear end of the forge free from the ground or floor, and then in moving the forge on the rollers B, when desired. 'Ihese arms L are also so arranged that they may be turned down out of the way when not in use.

The form or shape of the fire-bed is snch'as to 1'0-.

quire no dressing with clay or other material. The bed, being made of cast-iron or other suitable metal, will always keep the shape originally given to'it. Its

curved sides, in connection with the air-blast, keep the focus of heat away from these sides, and as their outer surface is constantly exposed to the surrounding atmosphere they are kept comparatively cool.

In the drawing the top plate of the fire-bed is represented as circular, but it is obvious that it may be of any form desired.

\Vhile fire-beds, having their walls more or less curved, or even funnel-shaped, may be used, we prefer to employ the combined fire-bed and tuyere made as described in our application forLct-ters Patent, of the same date with this application. \Ve also prefer to use a blower similar-in its construction to that for which Letters Patent were granted to us August 11, 1868, that is, a blower in which two coacting abutments are used, producing a positive blast. In this way we make a complete, compact, convenient, and portable forge.

Having thus described our invention,

\Vhat we claim is' 1. The combination of the blower H, having two coacting abutments, and metallic fire-bed and tuyere I, with the mechanical devices for operating same,

'when constructed and arranged as herein shown and described.

2. In combination with the metallic fire-bed and tuyere l and blower II, the valve 0, for preventing explosions, as set forth.

3. A portable forge, provided with the pivoted handles L and wheels B, connected to a single axle, substantially as described, for convenience in moving the
