摘要： 784,532. Winding yarns. FRASER & SONS, Ltd., D. Jan. 26, 1956 [Feb. 3, 1955], No. 3241/55. Class 120(2) In a yarn winding machine of the type in which packages are carried by cradles and wound by surface contact with driving rollers, each cradle being controlled by mechanism comprising a spring-urged follower bearing on a cam-shaped extension of the cradle, the controlling mechanisms for the cradles are arranged in groups of at least two mechanisms and each group is covered by a shroud common to that group. As shown, each cradle 2 of a backto-back arrangement protrudes through a slot 7 in a shroud 6 of inverted channel section which covers the cams 2 1 of the cradles 2 pivoted at points 4 1 and cam followers 5 1 , pivoted at 4 to the support 5 and urged by springs 8 into contact with cams 2 1 to hold each package 1 in contact with its driving roller 3. In a second embodiment (Figs. 2-4, not shown) the holders are arranged side by side in pairs, the shroud covering the cams, pivots and springs of each pair.

摘要： 759,403. Creels. FRASER & SONS, Ltd., D. March 15, 1955 [March 24, 1954], No. 8575/54. Class 120 (2). Apparatus for feeding sliver from rolls, of the type in which rolls of sliver are disposed in series in approximately end-to-end relation in a cradle constituted by parallel rollers and individually accommodated between spaced partitions disposed in parallel vertical planes transverse to the axis of the roller, is characterized in that each partition is arranged to intersect the common axis of the associated rollers at all stages of unwinding of the rolls and is formed as a sheetmetal structure with marginal edge portions which extend beyond the plane of the sheet portion. In the embodiment shown, each partition 4 consists of a web bounded, in part, by a skeleton frame 5 welded thereto and consisting of a round bar bent to form an arch, each end of the frame 5 being welded to a supporting-bar 6. In a second embodiment, the skeleton frame completely surrounds the partition which is supported to one side of the rolls 1 and 2 by a pin passing through two registering holes in the upper and lower flanges of a channel section. In other embodiments the partitions are supported from channel-shaped girders between the two rolls 1 and 2 or are hingedly supported on a rod running parallel to the rolls 1 and 2. Instead of the skeleton frame around the outside of the partitions parts of the sheet central portion may be dished outwards around the edge to form protuberances. Specification 737,421 is referred to in the Provisional Specification.

摘要： 751,964. Roller-clearers for carding-engines. FRASER & SONS, Ltd., D. Jan. 18, 1955 [Jan. 23, 1954], No. 2096/54. Classes 120 (1) and 120 (2). The drawing roller of a machine for carding long vegetable and artificial fibres is cleared by a floating blade adapted to rest against at least one abutment presented by a rigid fixed member and located intermediate the ends of the blade and adjacent the roller. The rubber shown comprises a blade formed in three sections 6, each carrying a tip 7 of wearresisting material, e.g. a laminated plastic, finger holes 20, and a replaceable retaining pin 9 engaging in a slotted hole 8 in a cross member 4 of the machine frame against a surface 5 of which the section abuts; the three sections are maintained in abutting relationship by distance pieces 19. Each section 6 is urged towards the roller 1 by springs, as at 14, each interposed between the bottom of a socket 12 and a plunger 11 the sliding movement of which therewithin is limited by a pin 15 projecting into a slot 16 and may be adjusted by means of a screw 17 adapted to engage an inclined face 18 of the plunger.

摘要： 723,176. Softening machines for jute &c. FRASER & SONS, Ltd., D. Oct. 5, 1953 [Oct. 10, 1952], No. 25409/52. Class 120 (1). In a fibre softening machine for jute, &c., of the type in which certain of a plurality of fluted rollers are driven by gearing from two side shafts 1, one on each side of the feed table 2, the two shafts 1 are positively connected to be driven by a motor 3 accommodated wholly within the confines of the machine. The motor may be disposed, as shown, so that the rotor axis extends parallel with the line of feed, and drives shafts 1 through spur gears 4 and chain gears 5, or through two trains of spur gears ; or the rotor axis may be at right angles to the line of feed, the gearing to shafts 1 including bevel gears.

摘要： 714,195. Preparing fibres for spinning. FRASER & SONS, Ltd., D. Dec. 31, 1952 IMarch 1, 1952], No. 5448/52. Class 120(1) Apparatus for producing sliver rolls of bast or leaf fibres consists in the combination of a hackling machine or spreader 1 of the type comprising slow-moving pins, fast-moving pins and a pair of drawing rollers, and a roll former 4 including driving rollers 5, the tractive force applied to the sliver by the driving rollers and the sliver roll pressing thereon being alone used to draw the sliver band through a condensing conductor 8 mounted between the drawing rollers 2 and the roll former; the delivery rollers which are usually used to draw the sliver through the conductor are dispensed with, whereby oil-in-water emulsion sprayed through a nozzle 20 on to the sliver passing through conductor 8 is not, as previously, largely squeezed out at the nip of the delivery rollers. The peripheral speed of rollers 5 exceeds that of rollers 2. Conductor 8, which is removable, is located in position by notched brackets 10 resting on a horizontal bar 11 on the hackling machine and a clip 17 engaging a plate 16 on the roll former. An angularly adjustable plate 14 projects inwardly through each side wall 13 of the conductor to control the width of the sliver band. The end portion of the conductor adjacent rollers 2 is hinged at 18 so as to be movable downwards in the event of lapping of rollers 2, this portion of the conductor being maintained in operative position by spring catches 19.

摘要： 707,923. Sliver feeding apparatus. FRASER & SONS, Ltd., D. Sept. 5, 1952 [Oct. 25, 1951], No. 24945/52. Classes 120(1) and 120(2) In apparatus for feeding sliver from rolls to drawing frames &c. the rolls of sliver are placed in juxtaposition in a cradle constituted by parallel rollers supported in bearings in stationary mounting members which are solidly connected solely by a single space bar parallel to the cradle-forming rollers and supporting a series of partitions spaced apart to accommodate a sliver roll between successive partitions of the series. As shown, cradle-forming rollers 3 for carrying a sliver roll 9 are supported in self-aligning bearings 4 in stands 5 and 6 spaced apart by a spacer bar 1. Partitions 2 are supported on the spacer bar 1 and are spaced apart thereon by distancepieces 11. The partitions 2 are rotatable about the bar 1 and have a depending limb 10 which rests on the floor. In another embodiment, the spacer bar consists of an angle-iron and the partitions are formed of tubing bent to inverted U-shape and clamped to the upstanding flange of the angle-iron.

摘要： 658,546. Sliver roll forming machines. FRASER & SONS, Ltd., D., and FRASER, H. March 21, 1949, No. 7569. [Class 120(i)] In a sliver-roll-forming machine having an endwise withdrawable arbor or pair of half-arbors provided with protruding pins or pin-like elements to engage the sliver, the pins or pin-like elements are individually set helically, i.e. skew to the axis of the arbor or half-arbor, their pointed ends being directed towards that end of the arbor or half-arbor last to emerge from the roll on withdrawal. As shown, Fig. 3, pins 1 are fitted at the larger ends of the halfarbors 2 of a machine of the type described in Specification 398,617, so as to point forwardly with respect to the direction of rotation; at commencement of winding the sliver passing between driver 6 and arbors 2 is arrested by an abutment 8, causing pins 1 to dig into the sliver. Pins may be similarly arranged. on the halfarbors of a machine of the type described in Specification 588,935, the arbors being initially driven with a surface speed slightly greater than the speed of travel of the sliver; or the pins may be orientated with their pointed ends trailing, the arbors then being driven at a lower surface speed than that of the sliver. A single arbor, Fig. 6, may be fitted with two sets of pins 11, 12. Instead of pins, spiked or serrated steel strips may be fixed to half-arbors. According to the Provisional Specification, the driver may be grooved to clear the pins.
