Title: Improvements in lathes for turning pilger and like rolls
IPC: B23Q35/10
Filed: 1951-07-10
Abstract: 700,570. Copy-turning. BECKER, H. July 10, 1951 [May 10, 1951], No. 16290/51. Class 83 (3) A lathe for turning Pilger rolls &c. has a toolcarrier rotatable in a horizontal plane for turning the arcuate roll surface, the carrier being simultaneously displaceable towards and away from the work by two or more cam discs, one at least of which is rotated in dependence on the rotation of the work and at least one other is rotated in dependence on the tool-carrier rotation. The work 1, Fig.' 1, is driven by gearing from an electric motor 2, which also drives an interconnected shaft 7, Fig. 3, for driving, through bevel gears 9, 10, and 45, 46 respectively, cam discs 12 and 45. Cam-disc 12, which corresponds to the cross-section of the finished roll, engages a follower 16 connected to a slide 15 which has a vertical groove to engage a roller 17 carried by a slidable rack 18. The rack moves in guides on a rotatable member which also carries a pinion 20 with which the rack engages. This pinion engages circular rack teeth on the end of a shaft 21 on the axis of the rotatable member and the motion is transmitted by further rack and pinion gearing to a rack 25, Fig. 2, on the cross-slide 26 carrying the tool. Angular rotation of the latter is effected by a worm wheel 29 forming part of the tool-rest and a worm secured to a shaft 31 which may be operated by hand with a crank or handwheel. Motion from the shaft is transmitted through toothed wheels 32, 33, the latter carrying a connecting rod 35, Fig. 1, which reciprocates a rack 34 and thus rocks a cam disc 41 on the end of a shaft forming the centre shaft of differential gearing 40, Fig. 3. The cam 41 rocks the rotatable member carrying the rack 18 through the arm 43, Fig. 1, and a follower roller thereon. The cam-disc 48, rotated from the work-spindle drive as described above, engages a follower on a lever 50 secured to the housing of the differential gear. In lieu of the crank and connecting rod drive for the cam-disc 41 an automatic toothed reversing-drive may be employed, Fig. 8, not shown.

Title: Improvements in or relating to bearings, particularly a combined radial and thrust bearing unit
IPC: F16C17/10
Filed: 1940-11-16
Abstract: 545,291. Bearings. FAST BEARING CO. Nov. 16, 1940, No. 16569. Convention date, Nov. 17,1939. [Class 12 (i)] A cylindrical journal or a thrust bearing has a stationary bearing-member with integral radial or axial projections connected by weakened flexible portions. A shaft 10, Figs. 1 and 2, extends through a housing 11 in two main parts 12, 13 provided with a sleeve ring 47 engaged by radial projections 52 on a sleeve 51 coated with a lining 60, the shaft 10 having a hub 35 secured 'thereto. The projections 52 are formed by straight, inclined, or arcuate surfaces 57 to provide weakened sections 56. Ring 47 and sleeve 51 are located within the housing by a screw 48 allowing slight relative adjustment but not rotation. The lining 60 has lubricant grooves 61 the lowest of which communicate with holes 63 extending through the lining and the weakened parts 56 of sleeve 51 to a reservoir in the base. The projections 52 have a spherical surface engaging a spherical seating in the ring 47 to allow for selfalignment, as shown in Fig. 1. The housing has end caps 16 with flanges 17 engaging the parts 12, 13 and annular projections 71 with spherical seats for spherical surfaces on rings 74 located on the caps 16 by resilient clips which allow slight relative adjustment but not rotation. The seats may be arranged at angles of 45 degrees or 60 degrees to the shaft. The rings 74 have axial projections 75 connected by weakened necks and provided with an antifriction lining. These projections engage the lateral faces of the hub 35 and the sleeve 51 to form a thrust bearing. Lubricating passages are formed in the projections to spread the lubricant circulated centrifugally by the end faces of the hub. The lowest passages are modified to return the lubricant to the reservoir. Modifications in the passages are described. The projections may be formed on a ring 99, Fig. 11, secured to the base ring 98 by pins 102 engaging feet 100 on ring 99 and by clamps 103 engaging notches in ring 98 and entering recesses in ring 99. The upper part 12, Fig. 1, may be notched at 145 to indicate the centre of the bearing, and the end caps may carry transparent plugs marked to indicate the working level of the lubricant.

Abstract: 825,763. Chucks. PRECISION INDUSTRIELLE S.A. June 4, 1956 [June 7, 1955], No. 17249/56. Class 83 (3). A chuck comprises two pairs of oppositely disposed jaws 11a, 11b, 14a, 14b, adjustable radially by levers 8a, 9a, operated by a fluidpressure jack which is freely movable axially of the chuck, levers 8a for jaws 11a, 11b being directed oppositely to levers 9a for jaws 14a, 14b, and coupled to the piston 32 of the jack by a member 30 which is coaxial with a member 31 coupling levers 9a to the cylinder 35 of the jack, so that movements of the piston and cylinder in opposite directions simultaneously operate the jaws. Fig. 2 is a section on line II-II of Fig. 1 and shows the opposite directions of adjacent levers 8a, 9a, which are rocked in the directions F, G respectively, to close the jaws, opposite pairs of which need not be 90 degrees apart. If the jaws are at different diameters, shorter levers are required for those at greater diameter in order to produce the same work-driving torque at each pair of jaws. The levers pivot on shafts 15 and have eccentric portions 16a engaging the opposed surfaces 18a, 19a, of pockets in jaw carriers 10a, to which the jaws are fixed by screws 12. The arms 22a of one pair of diametrically opposite levers are connected to the inner operating tube 31 by a member 25 prevented from rotating in relation to the chuck by a pin 26 on the chuck end plate 27, and those of the other levers are connected to the outer operating tube 30 by a member 29 interlocking with member 25. The jack is mounted on a spindle 1 and rotated therewith by a pin 43 in the driving pulley 3. A non-rotatable casing 45 is mounted on bearings 52 between a distributer 48, having annular grooves 53, 54 and a sleeve 51 fixed to the rotating cylinder 35 and provided with passages 55, 56 in communication with grooves 53, 54, and with the cylinder at both sides of the piston respectively. Pressure oil admitted to either side of the piston through conduits 49, 50 also passes between the distributer 48 and sleeve 51 to lubricate the bearings 52, and is discharged through a nozzle 57 which engages a frame 58 to prevent rotation of the casing. The piston is constrained to rotate with the cylinder by a pin 41 mounted on the piston, and the tube 31 forms a passage for coolant, or for the introduction of a control (not shown), for closing the chuck automatically when the work is introduced. Reference has been directed by the Comptroller to Specification 787,580.
