Abstract

1349994 Sewing machines SINGER CO 1 June 1971 [5 June 1970] 18344/71 Heading D1G A sewing machine has work edge guiding means mounted to engage the work and operative alternately with the work feed to turn the work. Engaging upper surface of work, presser foot. The presser foot 72, which is circular, pivoted at 129 to the presser bar 70, made of plastics and has a window of plastics or glass, is surrounded by a guidance ring 116 having an annular ring of teeth 120, the ring 116 being journalled by a bearing 118 in a plate 104 fixed to the presser bar at 100. A gear ring 122 on ring 116 is engaged by a gear wheel 124 driven through universal joints 174, 172 and an intermediate telescopic flexible coupling 94 by a servomotor (152 Figures 3 and 7, not shown). Rotation of the motor turns ring 116 to turn the work about the needle 44, the motor being operative only when the needle is in the work and the feed dog therefore disengaged from the work. To achieve this a lamp and photoelectric device co-operate with a reflective portion on the hand wheel rim, the intermittent output from the device controlling a modulator (190, Figure 7) in the servo circuit. Work supports, illuminating. The throat plate 60 is provided with a work edge sensing means comprising a p-n semiconductor bar 178 disposed normal to the feed direction and forward of the needle hole by one stitch length. Illumination falling on the bar from a lamp 130, through the presser foot window, varies according to the degree of overlap accomplished by the work edge, the output from the p-n bar providing the signal to the servomotor (152). The voltage bias on the p-n bar may be varied, to select the margin by which the seam is separated from the work edge.
