IMPROVEMENT IN PORTABLE FORGES.

Specification forming part of Letters Patent No. 202,461, dated April 16, 1878; application filed November 15, 1877.

To all whom it may concern:

Be it known that I, GEORGE B. PHILLIPS, of Bath-on-the-Hudson, in the county of Bensselaer and State of New York, have invented certain new and useful Improvements on Portable Forges, of which the following is a full and exact description, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a side elevation of my improved forge; Fig. 2, a vertical section, and Figs. 3 and 4 detached and enlarged details of the driving mechanism.

My invention consists of the combination and arrangement of the devices herein shown and described, for the purpose of producing a simple and eflective forge, complete in itself, and ready at all times for immediate use.

As shown in the drawings, A is the top plate of the forge, which I preferably make of a dishing form. It is supportedby the standard a and base a. It is provided with a tuyere-hole at its center, through which the air blast is discharged into the fire. An enlargement of the standard forms a chamber, B, for receiving the air-blast from the blower. At the bottom of this chamber is an opening for the discharge of the ashes falling from the forge into the chamber. This opening is closed by the cone-top valve 0, which is operated by the lever c, projecting through the side of the standard a. After passing through the opening in the bottom of the chamber the ashes fall down upon the deflecting-plate a and thence escape through an opening in the side of the standard. A trough, D, encircles the standard, which may be divided into compartments for holding coal, water, tools, 850.

E is a fan-blower, secured to the chamber B, into which it discharges its air; F, a stationary stud or shaft, (attached to the chamber '13,) upon which the mechanism for driving the fan-blower revolves. This driving mechanism consists of the following parts: A flywheel, G, which revolves freely on the stud F, and which has a disk, H, provided with an annular groove, h. In this groove the split clamp-pieces I are placed, as shown in Fig. 4:. These are provided with suitable openings at their joints for receiving the cam ends of the levers J, which, when pressure is applied and bind the fly-wheel and spool together so that the two will move as one piece. The studs 10 are fixed to the disk 76, and are so arranged that as the spool is moved backward sutficiently to release the flange 70 from the levers J, they (the studs It will strike against the ends of the 'clamp pieces and release them from their hold in the annular groove, thereby leaving the fly-wheel free to continue its rotations by the force of its acquired momentmn. passing several times around the spool K, has its opposite ends secured to the levers M. These levers should have elasticity enough to produce, suflicient tension on the cord to create the adhesion required to drive the spool. Said levers are attached to the lever N, which is pivoted to the bracket 0, secured to the chamber B. A spring, m, having its coiled end secured to the bracket 0, has its free end bearing upon the upper one of the levers M with sufficient force to overcome the resistance of the weight of the treadle and its attachments. P is the treadle, fulcrumed to the base a and connected to the arm N by the rod Q; R, a pulley on the shaft of the fan-blower E, running in frictional contact with the fly-wheel G, by which it is driven, and against which it is pressed by the spring S, which bears against the bearing T of the blower-shaft, which is movable for that purpose.

When it is required to operate the driving mechanism by hand instead of foot power, the rod Q is detached from the arm N, and the power applied to the hand-lever n, which may be detachable, if desired.

When the forge is used for melting precious metals, the perforated cap U,which covers the catches and retains the metal, in case the cruci.

L is the driving-cord, which, after ble containing it should be broken While instrncted to operate substantially as herein dethe fire. scribed I claim as my invention 2.
