Title: Sewing machine - has gripper mechanism which prevents jamming of the spool
IPC: D05B57/14
Filed: 1992-05-29
Granted: 1993-06-24
Abstract: A sewing machine with a gripper shuttle, has a freely revolving gripper with an internal spool, which is fixed. The gripper has a point to engage the loop of thread from the needle, and a cylindrical outer wall. There are sections cut away in the gripper and part of the race, at suitable positions for the interaction of the thread. In one of the cut-outs in the lip of the race, is a double sided projection, which has an operative purpose when a cut-out in the gripper is aligned to it. The cut-out in the gripper is in a region opposite the point. ADVANTAGE - The gripper permits a large spool, which runs quieter and efficiently. The spool is loaded easily. By clearing the thread from the needle loop, in the event of gripper reversal, the spool is not jammed.

Granted: 1994-03-31
Abstract: A conducting rocker (1) located swivelable at a swivel axis (4) contacts the recording carrier (2) at a point (3) with a set force (RP). A spring combination with a deflection spring element (5) applies a deflection moment on the rocker, and with a spring element (6) applies a compensation moment at the swivel axis. The working line of the spring force (10) of the spring element (6), in the initial position of the rocker free end, runs in a dead position to the swivel axis (4) so that the recording carrier force (RP) is determined by the deflection moment of the spring element (5). With the swivelling of the rocker (1) in the working range, the working line of the spring force (10) of the compensation spring element (6) is swivelled from the dead point, so that the compensation spring element exerts the compensation moment on the rocker (1). ADVANTAGE - Risk of harm e.g. tearing of recording carrier is minimised, so that processing reliability and quality of printer or copier is improved.
