Filed: 1970-06-25
Abstract: 1285824 Shoe drum brake FORD MOTOR CO Ltd 25 June 1970 [28 July 1969] 30839/70 Heading F2E In an internal shoe drum brake a shoe adjustment means 32 actuated on sufficient wear of the shoes through application of the shoes by a main brake actuator 36 is interposed between one pair 29, 31 of adjacent ends of the brake shoes 14, 16 and an anchor 26 secured to the backing plate 12 is interposed between the other pair 27, 28 of adjacent ends. A secondary brake actuating means, e.g. comprising a cam 53 and a lever 54, engages the shoes and is actuated to spread the shoes by a control assembly external to the brake. A connecting means, such as a cable 58 interconnecting the actuating means and the control assembly; passes through an opening 63 in the backing plate 12 and between the actuating means and the backing plate opening 63 engages one of the brake shoes or a component attached thereto e.g. a pulley quadrant 57. The arrangement is such that, on adjustment of the brake shoes due to wear the tension in the connecting means is increased. In the construction shown the shoe adjustment means 32 is actuated through a spring loaded cable assembly 48 which pivots a lever 44 mounted on the brake shoe 16, the lever 44 is operating with a star wheel 42 of the shoe adjustment means. The cable assembly 48 passes through a guide 49 of the brake shoe 16 and is secured to the anchor 26.

Abstract: 470,491. Reciprocating motors. WEYANDT, C. S. Nov. 8, 1935, No. 30911. [Class 35] [Also in Groups XXX and XXXVII] A conveyer trough vibrates with an up ward - forward anc downward - backwarc motion to move ma terials from a hopper the mouth of which extends so far into the trough that the accumulation of material on the trough retards the flow from the hopper ; electromagnetic means for vibrating the trough and the hopper either continuously or intermittently are described, consisting of a threearmed electromagnet 14, Fig. 2, the armature of which is mounted on a laminated spring, the ends of which are forked to embrace the screwed tops of pillars 27, 28 and are held between bevelled blocks 32, 33 adjusted by means of nuts 30, 31, 34, 35. The magnet is preferably energized by alternating current passed through a rectifier which suppresses alternate half waves. One half wave may be used to vibrate the trough and the other the hopper. Fig. 12 is a circuit diagram of the apparatus. When the switch 254 is moved to connect the terminals 253, 255 one half wave from the supply 251 passes through the rectifier 246 and the conveyer vibrating magnet 248 the other through the rectifier 247 and the hopper vibrating magnet 249. When the switch is placed to connect the terminal 255 with the terminal 265 and the terminal 267 with the terminal 268 current is supplied to a synchronous motor 270 which by means of adjusted pins 278 tilts a lever 279 carrying a mercury switch 272. When the switch is tilted the circuits of the magnets 248, 249 are closed through the switch terminal 282, 283 but when the switch returns to it horizontal position as the motor 270 passes on the circuits are broken. By closing a switch 256 the hopper can be vibrated continuously while the conveyer is vibrated intermittently. The amplitude of the vibrations can be regulated by means of adjusted impedances 258, 263. The period during which the switch is open can be controlled by moving the board carrying it and the lever 279 horizontally by means of a rack 290 and pinion 291.
