Title: Improvements in or relating to speed control systems
IPC: D01H1/36
Filed: 1925-11-13
Abstract: 260,430. Abbott, G. J. Nov. 13, 1925. Winding-on motions.-In a speed control system, especially applicable to bobbin-winding machinery, a spirally-grooved rotatable drum is provided having a groove approximately such that for any two points in the groove there is a constant ratio between the transaxial angles subtended at the axis of the drum by equal lengths of groove measured in the same direction from the two points, the ratio depending on the length of groove separating the two points; that is, if equal lengths of rope are successively pulled off the drum in a constant direction, the angles through which the drum will rotate during the successive stages vary geometrically. As applied to bobbin-winding machinery, the control system comprising the drums M, 0, Fig. 1, is provided to vary the gear ratio of the variable speed gear E to compensate for increase of diameter of the bobbin as winding proceeds. The flyer A is driven from the main shaft B through gearing B<1>, B<2>, B<3>, C, C<1>, while the bobbin J is also driven from the main shaft B through the variable speed gear E, spur wheels E\ E<2>, E<3>, a differential F, spur wheels H<2>, H<3>, H<4>, and bevel wheels K, K<1>. The gear E is preferably of the expanding pulley type, the effective diameter of the pulley being varied by the rotation of a threaded shaft L. The projection on a transaxial plane of the groove on the drum M is a hyperbolic spiral, while the groove on the drum O is such that successive rotations of the drum M through equal angles will cause successive equal changes in the gear ratio of the gear E. The drums are connected by a rope or belt P, which is fixed at one end to a point in the groove of the drum O while its other end carries a peg P<1>, Fig. 2, which can be inserted in any one of a series of holes M<1> in the groove of the drum M, each hole corresponding to a certain thickness of cotton being wound. The drums are rotated by a weight R, and the system is brought into action on completion of each layer by an escapement releasing a ratchet wheel and allowing it to rotate to the extent of one tooth. On completion of winding, the ropes P, R<1>, are rewound on the drums M, O by means of a hand wheel N<1>.

Title: Improvements relating to resilient pull and thrust coupling devices for use on railway rolling stock
IPC: B61G9/12
Filed: 1931-10-16
Abstract: 373,910. Combined buffing and drawgear for railway vehicles. KRUPP AKT.-GES., F., Essen, Germany. Oct. 16, 1931, No. 28793. Convention date, Jan. 5. [Class 103 (v).] Relates to combined buffing and draw-gear for railway vehicles of the kind in which draw-rods A, B at each end of the vehicle are connected at their inner ends by a coupling comprising a spring N, and are also individually associated with separate springs E, G. The coupling spring N is disposed between followerplates M, M<1> which co-operate with spaced stops c<6>, c<7> on the underframe C so that, when draught or buffing stresses are applied to one draw-rod only, the pressure exerted by the spring N is taken up by the underframe and is not transmitted to the spring associated with the other draw-rod. In the arrangement shown the draw-rods A, B slidable in bearing- plates c<1> are fitted with collars a<1>, a<2>, b<1>, b<2> normally abutting against follower-plates D, D<1>, F, F<1>, which are adapted to compress the springs E, G, and for this purpose coact with stops c<2> .. c<5> on the underframe. Secured to the inner end of the draw-rod A is a sleeve H, in the bore of which slides a head b3 screwed to the inner end of the draw-rod B, a smaller sleeve K being interposed loosely between the head b3 and follower-plate M<1>, while bolts 0 secured to the sleeve H pass through holes in the follower-plates M, M<1>. When draught or buffing stresses are applied to one draw-rod only, e.g. the draw-rod A, the spring N and the spring E only are compressed, the thrusts being absorbed by the stops c<2>, c<6> or by the stops c<3>, c<7> as the case may be. When both draw-rods A, B are subject to stresses, the two follower-plates M, M<1> move towards each other and away from the stops c<6>, c<7>, with the result that the pressure exerted by the spring N is not transmitted to the underframe. In a modification the stops c<6>, c<7> are spaced a slightly greater distance apart so that, in the normal or rest position, the follower-plates are not in contact with the stops.
