28 INTERNATIONAL EXHIBITION, 1876. by an eccentric, was connected with an arm of a rock-shaft having at its other end a second arm to which was adjustably connected a link that operated the feeding device. The shuttle was driven in a race, by means of a crank and link on the main shaft, these operating the shuttle-dri ver. The Whitney Manufacturing Co., Paterson, N. J. The machine exhibited by this company was designed to make the lock-stitch by means of a straight needle and a reciprocating shuttle. The needle-bar was reciprocated by means of a vibrating arm operated from a grooved cam-hub on the lower main shaft. A crank connected with this shaft, through a link, reciprocated the shuttle-driver to impel the shuttle in the race. The crank-arm -was made double, to operate a short shaft provided with a crank-pin to enter a slot in and vibrate a lever provided at its upper end with an inclined slot to embrace a pin on the feeding-bar and move it positively. The take-up lever was operated by the needle-bar. The tension device for the upper thread was a screw-like cylinder about which the thread was wrapped. In general appearance and operation the machine resembled the older form of machine made by the Weed Sewing-Machine Co. The Florence Sewing-Machine Co., Florence, Mass. The machines exhibited by this company made the lock-stitch. Their family machine is well known. It employed a curved needle, carried at the forward end of a vibrating arm, operated from a hori zontal shaft across the end of the machine. The shaft had a link connected with it that operated the shuttle-driver to move the shut tle in the race, the latter being arranged in a plane parallel with that in which the needle-carrying arm vibrated. A vibrating arm below the cloth-plate took up the slack of the shuttle-thread as the shuttle was moved backward. The feeding device had the usual four motions. A pivoted, grooved block, connected with the feed, was arranged to be more or less inclined either way from a vertical position, to govern the distance of the feeding movement in a forward or reverse dire’ction; or by it the feed could be stopped while the needle de scended twice at the same spot to tie a knot. A cam on the main shaft acted to take up the thread. The machine is more adapted for light family sewing than for heavy work. A manufacturing machine, built by this company for manufacturing purposes, employed a straight needle, carried by a needle-bar, operated by a trammel motion, having its centre placed eccentrically to the shaft that carried the disk in which were made the crossing grooves that received the trammel-
