Title: Improvements in Work Piece Holders
Inventor: KAMINGA SYLVAN JAMES
IPC: B23Q7/10
Filed: 1966-12-23
Abstract: 1,162,179. Machine tool details; milling. S. J. KAMINGA. 23 Dec., 1966 [3 Jan., 1966], No. 57746/66. Headings B3B and B3K. A workholder comprises jaws reciprocated between first and second positions by first actuator means, second actuator means for opening and closing the jaws and regulator means which control the reciprocation and activate the second actuator means to close the jaws as they reach the first position. Apparatus for receiving and clamping workpieces supplied from a magazine, conveying them past a tool e.g. a milling cutter, releasing them and then returning to repeat the cycle comprises jaws 20, 30 slidably mounted on waybars 12 and reciprocable together under the action of an actuating cylinder 24 and ram 23. A clamping cylinder 34 with a ram 35 is mounted on bars 32 extending from jaw 20 through the jaw 30 and operates to open and close the jaws. When moving to the left the jaws are open and adjustable stops 44 limit the travel of jaw 30 while a stop 54 causes workpiece locating fingers 51 to project from recesses in the jaw 30 when the jaws reach the left end position. A trip lever 66 mounted on jaws 20 is engageable with a sensor 64 and through a slight time delay controls the jaw closing action of cylinder 34 and ram 35. In its jaw closing position ram 35 operates a trip plunger 42 which through a sensor 62 initiates the feed of the jaws to the right. A plate 85 which is attached to the jaw 20 has a lost motion connection through nuts 83, 84 with a rod 82 of an hydraulic speed-control unit 80, the arrangement being such that initially feed is rapid and then slow as the workpiece passes the tool. The unit 80 includes two hydraulic compartments 86, 87, Fig. 16, connected by a restricted control passage 91 and a check valve 93, 94 which ensures that the speed regulating effect is only operative in the feed direction. A metering control 92 provides for adjustment of the speed-regulating effect. A sensor 65 operated by a trip arm 68 limits the stroke to the right and reverses the direction of the actuator 24 and a sensor 63 and trip arm 67 effect opening of the jaws immediately after reversal of direction to allow discharge by gravity of a finished workpiece. The sensors are adjustably located on bars at the side of the machine and may be hydraulic, pneumatic or electronic.

Patent GB-716599-A (GB)
Abstract: 716,599. Sights. MASSACHUSETTS INSTITUTE OF TECHNOLOGY. Oct. 2, 1944 [June 3, 1943], No. 18846/44. Class 92(2) A null indicating device, such as a bomb dropping sight, comprises means for indicating a line of sight, a gyroscope capable of precession through a small angle, said precession being free-of elastic restraint, means for displacing the sight line by an angle to the path of motion on precission of the gyroscope and thereby introducing an instability-producing torque proportional to d#/dt and stabilizing means to neutralize said tendency towards instability for all values of d#/dt. As shown in Fig. 1 the target is viewed through a mirror 6 of a bombing aircraft, the target being kept in line with the image of a reticle 8, the optical system for this purpose comprising a lens 16 and mirror 10. The mirrors 6, 10, are mounted respectively on rotatable shafts 7, 12, fitted with oilcontaining damping housings 13. The shafts are connected by links 28, 29 to the precession axes of two gyroscopes 20, 21. The gyroscopes are similar to each other and, as shown in Fig. 2, each has a rear trunion supported by radial wires extending from tangentially arranged leaf springs 32. The front trunnion is supported by a tensioned axial wire 44 mounted between arms 45 the trunnion being fitted with a framework 46 passing round one arm and being secured to the wire. The supporting wires 34, 44, by their resistance to twisting provide a centralizing torque which is neutralized by coil springs 48, Fig. 1. The precessional movements of the gyroscope are heavily damped by oil containers 49 partially filled with heavy oil, the gyroscope trunnions or rotor frame being fitted with rimmed discs 50 which extend into the oil. The damping coefficient is maintained constant by thermostatically controlled heating coils 52. In use the pilot keeps the image of the reticle on the target and if he has to manoeuvre the air. craft in doing so the gyroscope, free of elastic restraint and suitably stabilized, will move the image until a steady state condition exists in which the target and reticle appear stationary. This gives the correct angle of lead under ideal conditions and neglecting gravity. A super-elevation to allow for gravity is provided by applying a torque to the precessional axis of gyroscope 20. This may be done by a manually controlled knob serving to tilt the bracket 45 or by suitable connections to a flight indicator or gyro vertical. As shown in Fig. 6, a gyroscope trunnion has arms 86 carrying curved armatures entering soloniods 88. The latter are energized by a battery 89 and are in circuit with a rheostat 90 whose arm 93 is maintained vertical by a gyro element 94; the torque applied thus varies with the angle # of inclination of the aircraft to the horizontal and in practice is made proportional to cos #. In another construction, Fig. 1, the torque is applied by a weight 100 on an arm 101. Specification 684,667 is referred to.
