Abstract

621,431. Sewing-machines. BRUTSCH, A. MULLER-, and BRUTSCH, L., (trading as BRUTSCH & CO.). Feb. 25, 1947, No. 5427. Convention date, March 19, 1946. Drawings to Specification. [Class 112] [Also in Group XXIV] Treadle draving-gear; bobbin winding apparatus. -In gearing including an endless driving-belt passing round a treadle-actuated flywheel, the portion of the belt above the base on which the machine rests is covered by a casing and runs over a pulley on a shaft that is connected by a driving chain with the main shaft of the machine. The end of the belt-driven shaft may project from the casing and be adapted to receive a bobbin for winding, and' the chain-drive wheel may be connected to the shaft by means which are disengaged when a bobbin is fitted on the shaft (see Group XXIV). Belt tensioning means, adapted to compensate for a substantial variation in the height of the machine, may be provided.
