Abstract: 24,335. Milward, G. H. Dec. 7. Spindle apparatus. - Relates to apparatus in which the traveller or ring is driven and the drag is applied to the spindle, which is carried round by the tension of the thread. The spindle is carried in a bolster 5 fixed in the rising and falling spindle rail 3, the upper end of the bolster being fitted with a lubricating chamber or bush 7 and ball bearings 9 for the spindle, and the lubricant being conducted from the chamber 7 to the ball race by a suitable wick. The spindle may be provided with a disc or flange which rosts upon the balls of the bearing, in which case, by regulating the height of the footstep, the weight of the spindle may be supported by either or both of the bearings as desired. The stop 11 for preventing the withdrawal of the spindle when doffing may be removable. The drag is applied to the spindle by means of bell-crank levers 12, mounted in slots in the bolster, one end of each lever being padded, while the other is pressed upwards by means of a sliding ring 13, carried by a weighted lever 14, of which the weight 15, 16 is automatically moved along the lever to a greater or less distance from its pivot according to the diameter of the cop chase on which the winding is taking place. The weights 16 of the levers 14 are suspended by rollers 15 on the upper edges of the levers, and the rollers are moved along the levers by forks on an adjustable and horizontally-reciprocating rail 17. The rail 17 slides horizontally on brackets carried by the spindle rail, and in the vertical slots of sliding brackets 27, which are reciprocated horizontally by connection with the building-motion. The building-motion lever is connected with a lever 19, the forked en d of which raises and lowers a shaft 25 carrying a link 32, the end of which is provided with a stud engaging with a vertical slot in the slide 27 and with a radial slot in a quadrant 28. At the commencement of a set of cops, the slots in the slide 27 and quadrant are vertical and coincident, but, as the cop bottom is built, the quadrant is turned, so as to place the slot therein in an inclined position, by means of a ratchet arrangement 31, 30, 29, operated from the lever 19. When the cop has attained its full diameter, the pawl of the ratchet arrangement is automatically disengaged by the quadrant 28, and the horizontal movement of the slide 27 and of the drag weights continues uniform until the cops are completed. The yarn passes to the spindle through a notch in a guide-eye carried by a spring tube 34, which is sprung into the wharve 37, and the tube and wharve are carried by a set of four pulleys 38 which are mounted in ball bearings in the positions shown in Fig. 7, the wharve having a slightlybevelled flange engaging with the upper edges of the pulleys. The wharves and pulleys may be made by stamping from sheet metal. The driving- band passes from one end of a set of spindles to the other between the inner series of supporting- pulleys and the wharves and back again between the wharves and the outer series of pulleys. The pulleys may be mounted adjustably on the stationary rail 2, and some may be carried by spring levers to regulate the tension of the driving- band. For stopping a ring 34 when a thread breaks, it may be gripped by a pair of hand-levers K, which may be held in the gripping position by notches in the rail or by a spring catch 46.
