Abstract: 881,497. Gripping devices for handling articles. ATLAS-WERKE A.G. Feb 17, 1958, No. 5151/58. Class 78 (4). [Also in Group XVII] In a stacking device comprising gripper units A, B, provided with gripper jaws as described in Specification 881,496, and supported on a column 34 which is movable vertically in a sleeve 35 in a frame 33, downward movement of the gripper jaws is automatically terminated before the jaws contact a surface on which the articles are to be deposited or from which articles are to be picked up, so as to leave a small gap between the jaws and the surface. As shown, rods 28, 29, secured to the gripper units, are guided in bearings 30, 31 in the frame 33 and are provided with rack teeth 123 which engage gear-wheels 119 secured on a rotatably mounted shaft 120 which is provided with a free-wheeling device 118 and a braking device comprising an electromagnetic clutch 128. As the gripper units approach the article supporting surface, feelers 53, 54 which are supported in sleeves on the units, engage the surface, further downward movement of the units causing heads 53a, 54a on the feelers to engage buffers 135, 136 on tappet rods 51, 52, which, through switch-operating levers 132, 133, actuate switches 130, 131 incorporated in switch gear 49, 50 to actuate the clutch 128, thereby stopping the downward movement. The driving means for raising and lowering the gripper units may be controlled to provide a reduction in speed towards the termination of the downward movement of the gripper units and a switch may be operated to reverse the driving means as soon as the gripped articles are released. The gripper jaws may be locked in their open position as described in Specification 881,496. Specification 769,720 also is referred to.

Title: Improvements in and relating to disc brakes for vehicles
Inventor: BUTLER HENRY JAMES
IPC: F16D55/00

Abstract: 871,472. Disc brakes. DUNLOP RUBBER CO. Ltd. Feb. 5, 1958 [Feb. 19, 1957], No. 5535/57. Class 103 (1). A vehicle disc brake comprises an axially slidable disc 1, at least one fixed anchorage member 20, 21 to which is pivoted a carrier member 11, 12 supporting a friction pad 5, a further friction pad 5 secured to the vehicle body 6 or to a member 7 in solid abutment with the body 6 and operating means associated with a member 22 operable to pivot carrier member 11, 12 to bring pad 5 into contact with the disc and to slide the disc towards the body 1 to apply the brake. The member 22 is connected by a universal coupling 13 to 19 to carrier 11, 12, the upper end 13, 14 of which passes between fixed lugs 24 which relieve torque stresses set up in carrier 11, 12, the further pads 5 being secured in recesses 9 in the member 7 or body 6 by screws 8. The operating rod 22 is moved either hydraulically employing an hydraulic actuator, which may be operated mechanically, and a master cylinder, Fig. 4 (not shown), or a valve, or mechanically through a linkage or a cable, Fig. 5 (not shown). In Fig. 2 (not shown) the carrier is of rectangular form, the lower side being universally pivoted to the body to accommodate oscillation of the disc and each vertical side having a lug slidable between fixed lugs on the body to relieve torque on the carrier. Whilst in Fig. 3 (not shown) the carrier is in the form of en arm pivoted to the body to one side of the disc, the applying rod engaging a bell-crank lever having one limb pivoted to the arm, the other limb may be connected to an alternative applying means, the applying rod being prevented from moving axially out of the body. In this embodiment there is only one friction pad on each side of the disc. In the applying means shown in Fig. 6, the brake is applied mechanically through a pedal 85, 84, bell-crank 70 and arm 61; in an emergency, if the brake is required to be locked, then further depression of the pedal causes plunger 90 in rod 84 to connect pipes 83 and 88 to supply fluid pressure from the reservoir 92 by pump 94 to hydraulic actuator 95, 96 which acts as an additional boost, the actuator engages a pair of a series of dimples 87 on the bell-crank 70 and body 6 by which the advantage of the actuator can be varied, the brake clearance being adjusted by a screw 81. Specification 755,356 is referred to.

Turning-gear.-An electric or other starter comprises an actuating member 25 rotatable with and mounted for longitudinal movement on a shaft 9, the member 25 being adapted to control the rotary movement only of a driving member 12 mounted for rotary longitudinal movement on the shaft 9. means being provided for moving the members 12, 25 longitudinally in succession. In the form shown, the shaft 9 is driven from the electric motor 1 through a pinion 3 and a freewheel pinion 7. The member 25 slides on splines on the shaft 9, and the member 12 is a smoothbored pinion rotatable freely on the shaft. The members 25, 12 are moved axially by means of a plunger 49, the depression of which first moves the pinion 12 into engagement with the engine member 14, then moves the member 25 into clutching engagement with the pinion, and finally switches on the motor 1 by means of contacts 52, 53. The plunger 49 moves the members 25, 12 by means of a bell-crank lever 33 pivoted to links 36, 37 having slots engaging pins 45, 39 on yokes 47, 42, which slide on a shaft 41 and engage rings 28, 19 on the members 25, 12.

When the plunger 49 is actuated, the pinion 12 is moved immediately by the link 37, but the member 25 is not moved until the end of the slot 44 engages the stud 45 on the yoke 47. If the teeth of the pinion 12 should clash with those of the engine member 14, the pinion is turned by means of a pin 20 on the ring 19 engaging a helical slot in the hub 18 of the pinion, the ring 19 being held against rotation by the engagement of the arms of the yoke 42 with a ribbed flange 23 on the ring.
