INTERNATIONAL EXHIBITION, 1876. 34 pivoted at top and adapted to be moved laterally or vibrated at its lower end by means of a stitch-regulating lever having an adjust able fulcrum. The lower end of this stitch-lever was connected di rectly with the needle-bar vibrator, and as the stitch-lever was vibrated by the cam-shaped disk at the forward end of the main shaft, the vibrator moved the needle-bar laterally to feed the material. The presser-foot was held down by a spring, and lifted by a slotted lever having its fulcrum on the helper-bar, a friction-roller on the needle- bar entering a slot in the lever and lifting it at every down stroke of the needle-bar. A helper placed between the needle and presser bore upon the material when the needle was in the fabric, and as the needle moved laterally in the fabric the helper also moved laterally with it, and the needle and helper co-operated together to feed the material for each stitch. Were it not for the helper moving with and in ad vance of the needle, the material would be strained and liable to be bunched or drawn by reason of the strain- of the needle upon the goods. A slotted and vibrating take-up and thread-controlling lever was operated by means of a friction-roller on the needle bar. The shuttle was reciprocated upon a race by a driver. This class of feed has its advantages for some special work; no other family machine has a feed of this kind. McLean & Bennor Machine Co., Philadelphia, Pa. This company exhibited two machines. One, the “ Philadelphia Sewing-Machine,” is substantially like the machine represented in United States patent No. 101,292. The shuttle was held in an inclined position in a stationary shuttle-holder below the cloth-support and in line with the needle. A rotating hook operated by a crank at the end of the main shaft caught the loop of needle-thread, distended and passed it about the shuttle, forming a lock-stitch. The machine was provided with a reciprocating-rod or finger to twist and detain the loop of needle-thread, cast off from the heel of the shuttle, until the needle in its next descent passed through it. This enables the machine to make a twisted chain-stitch with a locking-thread. By omitting the shuttle- thread and permitting the finger and hook to operate, a chain-stitch may be produced. They also exhibited a cheap needle-feed sewing-machine, having under the cloth-support a vibrating thread-carrying looper, that, co operating with the needle, acted to form a two-threaded double-looped stitch. The machine was made in accordance with United States patent No. 105,961.
