Abstract

221,130. Sokal, S., (Adrian & Busch). Dec. 13, 1923. Lock - stitching by hooks. -The operative parts of a shoe-sewing machine are driven by links connected to a single lever pivoted on a fixed shaft and actuated by an eccentric. In the arrangement shown in Fig. 6 the caniers 10, 11 of a curved needle 18 and awl 19 concentrically mounted are connected by links 8, 9 to a lever 4 driven by the eccentric 1. The link 9 is attached by ball joints. The needle makes a small oscillation when in its retracted position for the purpose of freeing the barb from the thread loop. In the arrangement for driving a needle and needleguide shown in Fig. 8, an arm 23 rigid with the needle-guide 24 is connected by a link 25 to the link 22 connecting the needle-carrier to the lever 4. A mechanism for driving a thread-finger 31 is shown in Fig. 11, and comprises a link 25 connected to the needle-actuating link 22 and to a lever 23<1> pivoted to a fixed part at X and a link 33 connecting a point XI on the lever 23<1> to an extension 32 of the finger 31.
