Title: Improvements in or relating to drafting frames for spinning machines
IPC: D01H5/56
Filed: 1965-02-19
Abstract: 1,103,021. Drafting apparatus. SKF KUGELLAGERFABRIKEN G.m.b.H. 19 Feb., 1965 [20 Feb., 1964], No. 7333/65. Heading D1D. In drafting apparatus comprising a support and weighting arm carrying at least two top rollers cooperating with at least two bottom rollers, the bearing of at least one top roller and the bearing of its corresponding bottom roller are adjustable to adjust the spacing between the top rollers and between the bottom rollers, and the bearing-holder of the top roller is releasably lockable to the arm and is also connected to the bearing of the adjustable bottom roller, the connexion being releasable or flexible so as to allow the top roller, when it is locked to the arm, to be separated from the bottom roller by lifting the arm. In Fig. I, there are input, intermediate and output pairs of rollers 7, 2, 8, 3 and 9, 6 respectively, the lower rollers 3 and 6 being adjustable along a fixed support 1, and the upper rollers in a weighting-arm 11 secured on the working position shown by a connexion 13 to the support 1. The top input roller 2 is carried by a U-sectioned holder 22, Fig. 3, which houses loading-springs 10 bearing on a pivoted arm 17 carrying the rollerbearing. The holder is releasably and adjustably locked to the arm by a bolt 25 in a slot 11' in the arm; it is also secured, when in working position, to a member 27 upstanding from the bearing-block 2 of the associated lower roller by means of removable pins 28. The pins 28 when removed allow the arm and top roller to be raised. The arrangement also allows the sliver to be inserted and the roller spacing to be changed according to the length of the fibres being worked, when the arm is in working position. In the former case, a cam 30 is rotated by a handle 31 to engage beneath and lift the arm 17. In the latter case, the pins 28 are inserted and the bolt 25 released, the lower bearing block being shifted as a lever (52, Fig. 9 not shown) is rocked one way or another. The lever is one of a number connected to a shaft (51) which can be rotated from a central point so that the roller spacings of a number of frames can be adjusted together. In another form, Fig. 5, the holder 32 is again adjustably secured to the arm by a bolt 25, but the connexion to the associated lower block is through a flexible member 37. The holder and block are each connected to one of two elongated members which can slide but not rotate. Each member has a tapped internal bore receiving a threaded rod 34 or 42, the two rods being rotatable to adjust the position of the members and accordingly of the rollers when the bolt 25 is slackened. To this end, the rods are connected to worm wheels 41, 39, the connexion between the rod 34 and the wheel 39 being through a flexible shaft 37. The worm wheels mesh with a rotated worm 44.
