    • 546,511. Flyer spinning spindles; lubricators. FRASER & SONS, Ltd., D., and FRASER, G. S. March 28, 1941, No. 4199. [Class 120 (ii)] [Also in Group XXXIV] - In a wharve-driven flyer spindle having the vertical hollow spindle journalled in upper and lower antifriction bearings in a stationary housing with a suspended flyer and the driving wharve at its upper part, the bearings are lubricated by oil contained in a stationary sump and into which dips a rotor member carried by and coaxial with the spindle, the circumferential wall of the sump being disposed eccentrically to the spindle so that a convergent passage is formed between a segment of such wall and the periphery of the rotor member and the oil is swept frictionally by the rotating member into the passage and through a duct communicating therewith and from which the oil flows to the upper bearing. As shown the rotor member is a thimble 8 mounted on the hollow spindle 1 and disposed with its skirt portion partly immersed in the oil in the sump 7 formed within an integral base part of the stationary housing 4. Rotation of the thimble 8 sweeps the oil into the passage 10 between the wall 9 of the thimble and the wall 13 of the sump and forces it through a port 11 communicating with the duct 12 leading to the upper bearing 6 to which it passes through a port 14 disposed at the lower end thereof; the oil passes from the upper bearing through a port 17 to the annular space 18 between the bore of the housing and a tubular distance piece 19 and flows through the lower bearing 5 to the sump 7. In a modification the sump is formed in an annular plug screwed into the base of the housing and the oil from the duct 12 flows through a port disposed at the upper end of the bearing 6; a screw 25 may be provided for regulating the flow of lubricant through the port 11. The wharve 3 has a central depending boss 21 screwed on to the upper end of the spindle 1 and by removing bolts 24 the whole flyer assembly may be removed as a unit from the rail 23.

    • 694,573. Sliver-balling apparatus. FRASER & SONS, Ltd., D. May 28, 1951 [June 21, 1950], No. 15477/50. Class 120(i) [Also in Group XXXII] In a sliver rollforming machine of the type in which at least one arbor is movable relatively to one or more frictional driving surfaces. the rate e of movement being controlled by a dashpot. containing substantially incompressible liquid, the dashpot cylinder presents at one end at least a space containing a quantity of compressible fluid trapped by the operating liquid. As shown, during build-up of the sliver roll a piston 11 descends in a cylinder 1, displacing liquid from the closed lower end of the cylinder to the upper end through a bypass pipe 4 past a spring- loaded relief valve (not shown) and a needle valve 5. A recess 3 in the cylinder cover 3A accommodates compressible fluid which allows the liquid level to rise as the piston rod 12 enters the cylinder. A spring- loaded non-return valve 6 controls the rate of return of liquid to the bottom of cylinder 1 as the piston rises again; to reduce resistance to the rising of the piston, valve 6 may be opened manually by depressing a tappet 8. The lower side of the piston may be formed with a cavity constituting an auxiliary receptacle for compressible fluid. The operating liquid may be water or oil and the compressible fluid may be air or carbon dioxide; the liquid and the compressible fluid may be separated by a displaceable barrier such as a floating piston, a flexible diaphragm or bellows, or a bladder.

    • 588,935. Sliver-roll forming machines. FRASER & SONS, Ltd., D., and BROWN, J. S. Dec. 22, 1944, No. 25709. [Class 120 (i)] A sliver-roll forming machine has half-arbors and arbor-starting roll-confining discs, of less diameter than the finished roll, carried by arms adapted to be swung apart on completion of a roll, rotary driving discs engaging with the starting-discs at the start of roll formation, and a driving drum separate from, and non-coaxial with, the driving discs engaging the incipient roll, cheek-plates secured to the arms partially embracing the peripheries of the starting discs and covering the nip of the driving drum with the sliver roll. The roll 2 is formed on halfarbors 6 which are provided with starting discs 1 and are carried on pivoted arms 3 to which cheek-plates 4 are secured. On starting a roll, driving discs 5 and the incipient roll is driven frictionally by the driving drum 7. The cheek plates serve to position the expanding roll and together with a hanging back flap 8, guide the sliver while the arms are descending for a restart. The driving drum shaft 9 may be common to a group of machines. Specifications 323,416, [Class 120 (i)], and 398,617 are referred to.
