Abstract: 1,195,283. Superfinishing crank-pins. K. WIECK and W. HENTZEN, [trading as SUPFINA WIECK & HENTZEN], and BREMER VULKAN SCHIFFBAU UND MASCHINENFABRIK. 22 June, 1967 [22 June, 1966; 30 Dec., 1966], No. 28976/67. Heading B3D. Apparatus for superfinishing a crank-pin 2 of a crank-shaft 3 comprises at least one superfinishing tool mounted on a tool-carrier 18 adapted for location adjacent to the crank-pin and supported by a support arm 4 such that on rotation of the crank-shaft about its axis the tool-carrier follows the rotary path of the crankpin and provides relative rotational movement between the superfinishing tool and the crankpin, said support arm comprising a double parallelogram linkage 6, 6, 7, 7 one end of which is fixedly supported and the other end of which supports the tool-carrier. The parallel bars 6, 6 are pivoted at 8, 9 to a stationary frame 5 and at 10, 11 to an intermediate plate 12; the parallel bars 7, 7 are pivoted at 13, 14 on the plate 12 and at 15, 16 to a holding-plate 17 from which is fixedly suspended a tool carrier 18. The carrier 18 comprises U-shaped end plates 23, (24), connected by bolts 25; rollers 26, 27 mounted in the carrier engage the upper surface of the crank-pin. Superfinishing tools 19, 20 are mounted in carriages 21, 22 slidable on the carrier 18. Each carriage is guided on hardened guide rods 29, 30 and is moved parallel to the axis of the crank-pin by a nut 33 mounted in the slide which meshes with a threaded spindle 34 attached between the end-plates 23, (24) of the carrier, and which is rotated by a stopping mechanism 28. This comprises a toothed wheel 35 connected with the nut 33 and actuated by pawls 43, 44 pivoted to bolts 40, 41 actuated pneumatically by pistons 38, 39 in cylinders 36, 37. One unit 36, 38 serves to rotate the nut in one direction while the other piston 39 is in retracted position; reversal takes place at the end positions of the carriage. The number of switching steps per minute depends on the r.p.m. of the motor for rotating the crankshaft, and the total number of switching steps depends on the diameter of the crank-pin. In the superfinishing tools 19, 20 devices driven by compressed air are provided which are counterbalanced. The amplitude of vibration and the surface pressure of the stores can be infinitely regulated by pressure-relief valves.

Abstract: 995,455. Hydraulic apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 13, 1963 [Aug. 14, 1962], No. 30121/62. Addition to 967,632. Heading F1P. [Also in Division B3] A drive for increasing the speed of the headstock spindle of a lathe as the work-diameter is reduced comprises an hydraulic, positivedisplacement headstock motor 16 supplied by a similar pump 15, the motor and/or pump having a progressively variable output controlled by means 24 mounted on the lathesaddle 10 and operated by feed of the crossslide 12. As shown, the output of both the motor and pump, which are of the swash-plate type as described in Specification 893,848, are varied by servo-valves 29, 30 controlled by potentiometers 27, 28 which are operated, through cables, shafts or pipes, by followers 25, 26 engaging a cam 24. This is rotated, through a worm drive 22, 33, by a rack on the cross-slide 12, its operative sections having constant lift, Fig. 2 (not shown), ensuring constant cutting speed, the value of which is pre-set by axial displacement of the cam by a knob 36 to align the desired sections with the followers 25, 26. The cross-slide 12 may be driven by an hydraulic, positive-displacement motor (not shown) adjusted by a servo-mechanism controlled by a potentiometer which is operated by a cam 39 and a follower 38. The cam 39 may be adjusted relatively to cam 24 by a ring 46. A pressure-sensitive device 37, in the feedline 17 between the motor and pump, operates a potentiometer 45 which modifies the input to servo-device 30, compensating for leakages as described in Specification 963,991. The pump 15 is driven by an electromotor. In a modification, Fig. 3 (not shown), drive for the cam 24 is taken from the feed-screw of the crossslide. In a further modification, Figs. 4-6, the feed-handle 60 for the cross-slide, through gearing 61-64, also turns the cam 24. Axial follow-up movement of the cam to set the cutting speed is effected by a servo-valve 68 operated, through gearing 51-54, by a lever 50 which is set against graduated cams 55, 56, Fig. 5, for negative or positive feed. A reliefvalve 59 in the motor pump circuit is opened when the lever 50 is in its central position. The valve 68 is connected at 70, 73 to the ends 71, 72 of a cylinder housing a stationary piston 65 receiving pressure fluid through the piston-rod 66. Movement of the valve 68 to the left connects the passages 70, 73, causing a follow-up movement of the cam 24 to the left due to the difference in areas because of the piston-rod. Movement of the valve to the right connects passage 70 to exhaust 74, causing a follow-up movement to the right.
