Abstract: 28,278. Clark, D'A. M., [Brown Spin Wright Co.]. April 18. Driving-arrangements; spindle rails; spindle apparatus.-Relates to the application of positive-driving band mechanism, such as that described in Specifications 11,884/10 and 12,243/10, to spinning, twisting, and the like frames of ordinary construction, and comprises change-gear, as described in Specification 20,590/11, between the spindles and rollers for varying the twist, and means for lubricating the spindles and the driving-mechanism. The spindles are driven by means of a perforated metal band 1, Fig. 2, which passes around four pulleys 3, 4, 5, 6, one or more of which are provided with teeth 9 and serve as the actuating-members, their shafts being driven by rope-sheaves or belt pulleys, or by gear-wheels suitably enclosed to permit circulation of lubricant by means of a pump and operated from a source of power which may comprise an electromotor. The band is kept taut by means of a screw shaft 85 which engages the bracket that carries the pulleys 4, 6. The pulleys 3, 5 are of suitable diameter, say seventeen inches, to prevent deterioration of the band. The pulleys 3, 4, 5, 6 are carried in pans 66, 76, which are secured to the spindle rail and are connected by covered troughs or conduits 100 of compressed fibre, so that lubricant will be splashed forward by the driving-band over the spindle gears and circulated through the conduits and pans. If a band is used for each row of spindles, as shown in broken lines 10, 11, a return conduit 12 is fitted. The conduit is held in place on the spindle rail by the flanges 33, Fig. 3, of the spindles and is provided with a cover 104. Ports 120 through which oil passes to the spindle bearings are arranged at such a height that detritus will not enter but will be carried along by the oil to a sump 122. The gears 44 on the spindles are supported by springs 190 and may be in one piece, or in two pieces connected together by prongs 195, which in both cases secure the gears to the spindle blades as described in Specification 11,885/10. The bolster 206, Fig. 4, is of ordinary type having ports and grooves, through which the lubricant passes and finally escapes through ports 214 in the bolster, bushing 205, and the gears. The bushing 205 is made of brass and is either free or fixed to the gear or bolster base. A curb 216 serves to guide the lubricant to a port 120 in the bolster base. A nipple 232 secured by means of a bayonet joint to a metal rail 230, or a slide arranged between the metal rail and the cover of the trough serves to hold the spindle in place during doffing. The trough may be inverted and bolted to the spindle rail, a packing consisting of a layer of lead with layers of rubber on each side forming a joint between the trough and rail. The lubricant circulates through the spindle bearings and the excess escapes through ducts in the rail. A catch on the trough engages with a shoulder on the spindle wharl to prevent displacement of the spindle. The pressure of the lubricant is, as described in Specification 28,029/09, sufficient to float the spindle out of contact with any metal surface. The lubricant is supplied from a storage tank by a rotary pump which may be driven from the rollers. A nest of graded gear-wheels 150 is interposed between the shaft that drives the spindle-driving pulley and the roller shaft 174, as described in Specification 20,590/11, three selective gear-wheels, any one of which may be geared with any one of the wheels in the nest, being provided in order to vary the twist. The selective gear-wheels are splined on a shaft geared with a countershaft 130 connected with the shaft of the spindle-driving pulley. The building-motion shaft is driven from the shaft 130 through worm, sprocket, and chain gearing, or through additional shafts provided with universal joints. Teeth 9 are secured in grooves in the driving-pulley by means of nuts, and the pulley may comprise a spider 183, Fig. 6, secured to the shaft and carrying a rim enclosed by an annular conduit 189 to receive lubricant. Two or more of the shafts carrying the pulleys 3, 4, 5, 6, may be connected by any suitable gearing.
