Title: Improvements in or relating to vibrating conveyors and the like
IPC: H04N9/20
Filed: 1948-04-27
Abstract: 663,627. Screening apparatus. GENERAL ELECTRIC CO., Ltd., and SHERWEN, J. W. April 27, 1948. No. 11542/48. Class 117. [Also in Group XXX] A vibrating conveyer (or screen) (Fig. 1) comprises a material containing trough 4 having a first means (e.g. magnetic vibrator 21) to reciprocate the trough in either direction of conveyance; a second means (e.g. magnetic vibrator 9) to reciprocate the trough in the up-and-down direction; and means for changing the relative timing of the two reciprocations to select, one of the two desired directions of movement of the material. Fig. 1. - Rigid frame 1 rests resiliently on rubber shoes 2 and carries on bracket 25 the core 23 of magnet 21, the armature 22 of which is fixed to trough 4 resiliently supported by leaf springs 5 fixed to frame 1 so that energization of the magnet 21 reciprocates the trough horizontally. Also, secured to frame 1 by brackets 11 is the core 10 of magnet 9, the armature 12 of which is fixed to pendulous weight 13, the latter resting on springs 14-15 on the brackets 11, so that energization of magnet 9 causes the up-and-down reciprocation of the pendulous weight 13 and the vertical vibrations are transmitted through frame 1 and springs 5 to the trough 4. Trough 4 therefore receives two sets of vibrations. The A.C. current used may be rectified using one halfway metal rectifier for each magnet, and reversal of current through one rectifier serves to reverse the direction of conveyance by thus changing the phase of the impulses in the one direction. Fig. 4.-The two vibrations are applied to trough 35 by magnets 40 and 41, which magnets together with trough-supporting springs 36 rest on plate 37 secured at its centre by packing plate 39 to frame 38 resting on rubber feet 49, the flexibility of plate 37 contributing to the vibration of the trough. Two or more such troughs may be coupled together to form a single longer trough.

Title: Improvements in and relating to toothed gearing
IPC: F16H37/00
Filed: 1932-04-22
Abstract: 389,293. Toothed &c. gearing. CAGE, J., 34, Regent Street, Valley Stream, New York, U.S.A. April 22, 1932, No. 11652. Convention date, May 8, 1931. [Class 80 (i).] In toy tip-wagons &c., two or more mechanisms are selectively brought into gearing engagement with a continuously rotating driving-shaft. The driving-shaft 12 is driven by an electromotor 57, connected by flex to an electric plug, through worm and bevel gearing, and carries a pinion 13 engaging a pinion 21 on a pin 20 in a carrier 15, 16, which is supported on the shaft 12 and is driven through a friction washer 19 by tha pinion 13. Pinions 28, 29, 30 are carried in fixed bearings so as to be engaged in turn by the pinion 21 as the pinion 13 and carrier rotate. If the carrier is unrestrained, the pinion 21 rolls idly over the pinions 28 &c., with the friction drive temporarily slipping, so that no power is transmitted. The carrier has, however, three lugs 18 which are engageable by a hook 34 on an electromagnet armature 33, except when the magnet is energized by closing a switch, so that the carrier may be held with the pinion 21 in selected engagement with the pinions 28 &c., which are thereby driven. Alternatively, a single lug 18 and three electromagnets selectively operated may be used. The pinion 13 may be replaced by chain gearing driving the pinion 21 from the shaft 12. The pinions 29, 30 are respectively geared to wheels 45 &c. driving the road wheels of the wagon in forward and reverse directions. The pinion 28 drives, through bevel and worm gearing, a crank arm 53 which tips and lowers the dump body through a connecting-rod 55.

Filed: 1962-04-04
Abstract: 967,959. Retractive switches; mechanical switches without quick action; switches held set and freed mechanically. J. C. RIDOUT, and W. F. HILL. July 2, 1963 [April 4, 1962], No. 12853/62. Heading H2B. [Also in Divisions G4 and H3] A switch for a vehicle turn indicator system giving two indications on either side of a vehicle (see Division G4) comprises a lever arm 1 rotatable about an axis 15 and also about axis 18. Movement about the axis 15 operates a linkage to rotate shaft 5 moving the contacts of a first switch mounted on a disc 8 to connect either the left hand or right hand indicator lamps to the flasher. Secured to shaft 5 is a member 11 which retains the switch in its operated position by means of a spring-pressed roller 12. Return movement to the deenergized position is assisted by action of roller 12 on cam surface 13. Movement of lever 1 to the right about pivot 18 closes a second switch by forcing member 16 into engagement with spring contact 14 (Fig. 3). This spring contact 14 is not capable of holding member 16 in the switch closed position so that this second switch cannot be left closed when the lever arm 1 is in the central position for the first switch. In order to lock this second switch the lever arm must first be rotated about axis 15 to operate the first switch. In either of the operated positions of this first switch disc 11 is rotated to bring one of the abutments 20 under the end of spring contact 14 so that member 16 is held against the action of return spring 17 until member 11 moves to the off position.
