IMPROVEMENT IN PORTABLRFORGES.

Specification forming part of Letters Patent No. 192,975, dated July 10, 1877 application filed April 21, 1877.

To all whom it may concern Be it known that we, WILLIAM E. OANEDY 1 and FRANK LARSON, of Rochester, in the of a top view, and Fig. 2 a longitudinal cen-,

tral section, of our improved forge. This invention has relation to improvements in portable forges; and it consists in a bellows composed of an upright cylindrical body having at each end a flexible cap forming airtight joints therewith, and a rigid head in each cap, which cylinder is divided into two chambers by a valved diaphragm, and is connected with the fire-place by a tube opening at one end in said cylinder, and at the other into the fire-place of the forge, above said (liaphragm, and, in connection therewith, of a vibrating lever operating the lower cap, and connected with the vertically and horizontally vibrating lever, that is arranged above and operates at each descent the upper cap, as hereinafter described and claimed.

In the annexed drawings, the letter A designates a rectangular wooden frame, that is supported in a horizontal position by braced legs B, and whose side rails are provided at each end with handles a, by means of which the frame and the forge supported thereon may be readily transported from place to place. 0 represents a sheet-metal plate, having at its center or thereabout a depression, 0, in which the coals used in heating metals for forging or tempering purposes will be deposited, and at each side and at one end farthest from the bellows E, a ledge, b, serving to prevent waste of coal.

At the end next the bellows is a vertical metallic guard, D, that may be formed in one piece with the hearth O, that serves to protect the fire fromadverse drafts, and prevent the coals from falling off the hearth aforesaid, at this end.

At the rear of the guard D is located the bellows E. This is composed of a preferably cylindrical metallic body, d, extending above and below the frame A, so as to lower its center of gravity between its side rails, and of two heads, F F, respectively at its upper and lower ends, composed each of a conical leather or other air-proof part, c, and a wooden or other head, f, of less diameter than the cylinder aforesaid. The lower head, f, is provided with a valve, g, opening upward, and a like valve, 9, is placed in a diaphragm, Gr,arranged in the cylinder at or near its middle. The body (1 above the diaphragm is connected with the depression a at its bottom by a pipe, h, decreasing in diameter from the body to the depression, so as to concentrate and intensity the blast.

H represents a vertically-vibrating lever, that is pivoted at one end to a brace, h, of the frame, and extends below the bellows from end to end of the same. This lever is connected, by means of a bolt, 7L2, with a metallic plate, 71, that bridges the valve opening in the lower head, f, and is actuated through the medium of a connecting-rod, J, by a lever, I. This is fulcrumed in an arm, K, having its hearings on the upper end of an up right, L, of the frame, and vibrating horizontally thereon, so that the said lever has both horizontal and vertical movement. It is thrown across the upper head, f, of the bellows, and actuated in the usual manner. At each upward movement thereof the lever B will be depressed, admitting air into the bellows, that, at the downward stroke of the same, will be forced upward into the upper part-of said bellows through valve g of the diaphragm. At the same time both the flexible heads will be compressed, and the air both above and below said diaphragm forced through the tapering nozzle into the hearth or fire-place in a very strong current.

What we claim as new, and desire to secure by Letters Patent. is-

1. The combination, with the bellows E, having a cylindrical body portion, 01, valved diaphragm G, and the upper flexible cap F, and the lower flexible cap F, of the lever H, connecting-rod J, the vertically and horizontally vibrating lever I, arranged over and operating to depress at each descent the upper In testimony that we claim the above we fle'xiblecap F, the conduit h, and the hearth have hereunto subscribed our names inthe of the forge, substantially as specified. presence of two witnesses.
