Title: Improvements relating to electric control switch adapted for control movement of a machine tool element
IPC: H01H19/62
Filed: 1955-03-08
Abstract: 781,388. Boring and milling machines. NEW BRITAIN MACHINE CO. March 8, 1955 [March 12, 1954], No. 6773/55. Class 83 (3). [Also in Group XXXVII] A boring and milling-machine is controlled electrically by switches in a pendant-control H, Figs. 1 and 5, these switches (see Group XXXVII), each comprising an operating-lever such as 169 movable to left or right from a central position to which it is biased, and latchable at will by a further movement so as to engage behind an ear 222. Switch 169 causes a motor to drive the tool-spindle 17 in one direction or the other through variable-speed gearing which terminates in a shaft 28, Fig. 3, which in turn drives a sleeve 43 through more variable-speed gearing K. The spindle 17 is slidably keyed within the sleeve 43, which also drives, through gearing L, a shaft 61 driving the wheels 67, 69 in opposite directions. Operation of switch 170, Fig. 5, energizes one of two electromagnets 74, 75, thereby clutching wheel 67 or 69 to a shaft 64 which drives a screw 53 and so feeds the spindle 17 in either direction. Electric circuits (see Group XXXVII), ensure that the feed direction corresponds to the movement of the switch, irrespective of the direction in which the spindle is rotating. If it is desired to traverse the spindle rapidly, switch 171 is operated. This energizes a second motor 23 which drives shaft 61 through an over-running clutch 59. Switch 172 controls the vertical movement of the spindle-head C and back-restblock G, Fig. 1, and switches 173, 174 control the sideways movement of the saddle E and the backwards movement of the table F. All these movements are effected by a third motor 22, Fig. 4, which drives a shaft 118, either slowly through variable-speed gear N or rapidly through a clutch P operated by an electromagnet 106 controlled by a push-button 175, Fig. 5. The shaft 118 rotates gearing which may be clutched by electromagnetic clutches S, Q and R to screw-shafts 16, 18, 124 and 130, which respectively traverse the spindle-head, back-rest-block, saddle and table. Alternative hand control is also provided.

Title: Improvements relating to clutch devices
IPC: F16D7/00
Filed: 1925-03-12
Abstract: 248,183. Humfrey, J. C. W., and Sandberg, C. P.[Firm of]. March 12, 1925. Addition to 239,894. Clutches, friction.-In clutches comprising skewed rollers interposed between concentric curved conoidal members and caused to jam by axial motion of one conoid, as described in the parent Specification, the axial movement of the conoid in the engaging-direction is arranged to be positively and variably limited, so that the degree of jamming, and consequently the maximum torque transmissible in forward drive, can be adjusted. In clutches with a single pair of conoids, the disengaging-movement is elastically resisted, so that free-wheel action is permitted. In a biconoidal clutch for transmitting variably-limited torque in both directions of drive, skewed rollers F, Fig. 1, are interposed between double conoids D, E secured to a casing C on the driving-shaft A and splined to the driven shaft B respectively. Arms L, rocked by a quadrant O and worm P, act through thrust bearings I<1>, I<2> on a sleeveextension H of the conoid E to displace it to any extent on either side of the mean position according to the direction of drive. The interposition of a spring R, Fig. 3, between the bearing I<1> and a shoulder J of the sleeve H allows overrunning when the sleeve is shifted to the left, while, by shifting the sleeve to the right, a braking-effect can be obtained or a reverse drive transmitted without torque limitation. By supplying lubricant to the clutch, torque above the normal static limit can be transmitted, such torque being a function of the velocity of slip.

Title: Improvements in or relating to blenders
IPC: B01F15/02
Filed: 1959-02-27
Abstract: 872,903. Blending granular materials. WILLIS, H. C. A. Feb. 29, 1960 [Feb. 27, 1959], No. 6827/59. Class 86 Apparatus for blending in pre-determined proportions by weight grain of different varieties differing in bulk density comprises for each variety a rotor having four containers 10 and adapted to rotate through successive 90 degree intervals by a pawl mechanism (not shown). Grain is admitted to the uppermost container and discharged into a common bulk when it reaches the bottom position; after the initial movement the rotor will rotate under the weight of the grain only. The containers 10 have moveable false bottoms 12 and the volume of all four containers on one rotor may be adjusted simultaneously by a handwheel 13 and an indicator 16, Fig. 3 (not shown) to take into account the bulk density of the variety of grain so that the final blend may be in proportions by weight. Each rotor is controlled by a rotating pulsator disc 18, Fig. 7, having ten concentric rings 19 of electric contacts, the innermost ring having five contacts and the number increasing by five in each ring. A calibrated member 24 carries a sliding contact which may be adjusted to co-operate with any one of the rings; each time the circuit is closed the pawl mechanism is actuated to permit the associated rotor to rotate through 90 degrees. The discs for all the rotors in the blender are driven at a common adjustable uniform speed (see Figs. 4, 5 and 6, not shown) so that the proportion by weight of each type of grain in the blend may be controlled by appropriate setting of the sliding contacts on the members 24 and of the handwheels 13.
