Abstract

745,474. Sewing-machines. TRUBENISED (GT. BRITAIN), Ltd. Sept. 9, 1954 [Sept. 11, 1953], No. 25183/53. Class 112. Means for guiding a workpiece under the needle of a sewing-machine along a predetermined stitching line comprise a work-supporting carriage mounted for independent movement in two mutually perpendicular directions in a horizontal plane, a telescopic arm pivoted at its lower end for movement in a vertical plane parallel to one of said directions, a head carried on the other end of the arm and engaging the carriage for movement with it in said one direction but being movable relatively thereto both vertically and in the other said direction, means for causing swinging movement of the arm, and a linkage carried by the arm for causing extension and contraction of the arm, when the latter swings, to constrain the head to move along a horizontal path. A frame 7, for holding shirt collars, is supported by a carriage 8 slidably mounted for movement in a longitudinal direction on parallel rods 9 supported at each end by sleeves 10 slidably mounted for movement in a transverse direction on stationary rods 11. Longitudinal movement is imparted to the carriage by a telescopic arm 23, the outer member of which is pivoted at its lower end to a stationary pin 24 and the inner member of which is pivoted at its upper end to a pin 22 carried by a head 20 which is disposed within a vertical-walled transverse channel in the carriage and carries rollers 21 which engage the channel walls. A sleeve 31 is slidably mounted on the outer member of the arm and carries a pin 35 rotatably mounted in a slide 36 longitudinally movable on stationary rods 37, a pin 38 carried by the slide engaging in a helical groove provided in a cylinder cam 39 fixed to a shaft 18 which is driven by gearing 19. A double-armed lever 32 is pivoted to sleeve 31, a link 33 is pivoted to one arm of lever 32 and to the pin 22, and a link 34 is pivoted to the other arm of lever 32 and to the pin 24, the lengths of the two arms of the lever bearing to one another the same ratio as to the lengths of the two links. The transverse movement of the carriage is small compared with the longitudinal movement, and is imparted by means of a pair of levers 12 fixed at their lower ends to a longitudinal shaft 13 and pivoted at their upper ends to blocks 15 slidably disposed within vertical cheeks provided on the sleeves 10, a pin 16 on one of the levers engaging in a groove provided in a cam disc 17 fixed to shaft 18. Specification 709,621 is referred to.
