Title: Improvements in looper mechanism for sewing machines
IPC: D05B57/02
Filed: 1952-07-31
Abstract: 709,545. Sewing - machines. UNION SPECIAL MACHINE CO. July 31, 1952 [Aug. 3, 1951], No. 19362/52. Class 112 Chain-stitching with eyed needles. The looper carrier or looper mechanism may be disconnected from its driving means for the looper to be moved to a position in which it is accessible for threading, but this disconnection is prevented when the needle is in any position intersecting the looper path. In the mechanism shown, for a multi-needle machine, the loopers 112 and needle-guards 114 are adjustably clamped on a bar 110 forming part of a looper-carrier 92 which is freely mounted on a shaft 76; the loopers have no needleavoiding movement, and co-operating with them are loop-spreaders (not shown) in the form of fingers clamped in apertures in a rod which is reciprocated parallel to the shaft 76 by connections from a cross-shaft oscillated from the main shaft 30. The looper shaft 76 is oscillated from the shaft 30 by an eccentric 84 and arm 78, and has fixed to it an arm 88 with an aperture 90 which is normally engaged by a sliding bolt 102 mounted in lugs on the loopercarrier 92, under the action of a spring 106, so that the loopers are oscillated with the shaft 76. In the form shown, a plunger 118 slidably mounted in the machine frame, its motion being limited by a finger-knob 122 and a collar 124, has secured to it a forked arm 128 which engages between a head 108 of the bolt 102 and a spring- pressed washer on the bolt, so that when the spindle 118 is pulled to the left the bolt 102 is withdrawn from the arm 88 and the loopers can then be moved forward to a suitable threading position by rotating the spindle 118 or by a torsion spring 140 provided for that purpose on the shaft 76. The arm 128 is at all times in engagement with the bolt 102, but withdrawal of the bolt is prevented at such times as the needles are within range of the loopers by engagement of a tooth 134, on the arm 128, behind a tooth 136 on a bracket fixed on the machine frame. In a modified arrangement, the bolt 102 has an enlarged head and the arm 128 is replaced by a disc, the combined diameters of the head and disc being such that these parts can only engage when the looper-carrier is in that part of its cycle of movement when the needles are above the looper paths; in this arrangement the interlocking teeth 134, 136 are not required, and the looper-carrier has to be moved to its operative position manually. Feed by wheels. A puller feed comprising toothed rollers is provided, the upper one being driven by spiral gears from a vertical shaft and being spring-pressed downwards; means are provided for lifting this roller from the work. As the rollers need to be of substantial length to cover the width of work acted on by several needles, the work-support must have a slot of similar length; the work is prevented from being drawn into this slot by a wire fixed across the middle of the slot and accommodated in a 'peripheral grove in the lower roller. Specification 259,208, [Class 112], is referred to.
