Abstract
215,884. Singer Manufacturing Co., Ltd., Corrall, H., and Stevens, B. A. March 5, 1923. Sewing-machines; feed by presser-foot; worksupports; work-guides; needles-guides.-A sewing- machine which is specially adapted for sewing purses comprises a throat plate, part of which is inclined at an oblique angle to the direction of the needle, and a feed member carried by an arm pivotally mounted and inclined at the same angle as the throat plate. An eye-pointed needle 10 cooperates with a shuttle oscillated by a pitman 13 connected by linkage to the main shaft. The needle enters a slot in the inclined part 23<1> of a throat-plate a horizontal part 23 of which is secured to the work-arm. A feeding-foot 24 is mounted above the plate 23<1> on an arm 27 pivoted at 29 to a bracket 31 rotatable about a vertical stud 32. A guide 33 located above the feed-foot is carried by an arm 35 also pivoted at 29 and pressed towards the arm 27 by a spring 39. Feeding movements are given to the arm 27 by mechanism comprising a face cam 42 on the main shaft acting through levers to rock a shaft 48 and arm 49 which is connected by a link 50 to a lever 51. A block 52 on the lever 51 has detachable engagement with a ball 53 on a rod 54 clamped by a screw in a socket 56 on the feed-lever. The lever 51 is pivoted at 63 to a cross-head 62 carried by a spring-depressed bar 59. A rod depending from the cross-head engages a cam 64 on the main shaft, which thus communicates lifting movements to the lever 51. The bar 59 carries a bracket 68 which is engaged by a hand-operated cam 71 to raise the lever 51 and the feed-foot. A stationary needle guard 72 is secured to the horizontal portion 23 of the throat-plate and forms in conjunction with the bevelled end 74 of the feeding foot a grinding means for the work. An edge-guide 77 sliding between the guard 72 and the throat-plate is provided with a lateral arm 78 to which is pivoted an arm 79. The guide 77 is retractible from operative position to allow the tab of a purse to pass under the guard 72 by pinching together the arm 78 and a spring-influenced catch-lever 81 having a notched arm 83 which engages a pin 84 on the arm 79. An extension 85 of the throat-plate is held by a spring against the forward edge of the part 23<1>, but may be swung aside. In operation the feeding foot is raised and shifted for a fresh feeding operation while the needle is in the work.
