Title: New or improved motor vehicle transmission
IPC: F16H15/10
Filed: 1921-05-17
Abstract: 184,854. Roots, J. D. May 17, 1921. Variable-speed friction gearing.-The road wheels of a motor vehicle are directly driven by friction discs engaged by rollers on the engine or propeller shaft, the disc and roller gearing being enclosed in a. casing having tubular extensions which enclose the wheel axles. The propeller shaft I rotates in a bearing F<1> carried by a vertical rocking shaft F, so that the shaft I can be rooked to bring each of the driving rollers H, H<1> against the appropriate driven disc C, C<1>. The discs are slidable on the road wheel axles B, B<1> and are either splined or keyed thereto, or are connected thereto by springs, D, D<1> which allow differential rotation of the road wheels on curves. The springs, in either case, serve to press the discs towards the driving rollers. The front bearing K of the propeller shaft slides in a guide and is controlled by cables E<4>, K<5> passing round pulleys M to a pin N, Fig. 4 sliding in a handlever O and controlled by a spring P which keeps the cables taut. The rollers are shifted along the shaft I to vary the speed by means of bell-crank levers G<4> operated by a hand-lever L through linkage and a rod G' passing through the shaft F. The lever L is locked by a detent L<2>, and when this is released the pin N is pulled downwards by a flexible cable connection R to slacken the cables K<4> and relieve the pressure on the driving rollers. The driven discs are formed with bevelled flanges C<4> engaged by corresponding surfaces on the driving rollers, in order to obtain greater friction surfaces in the low gear positions. The edges of the discs are engaged by brake blocks or bands U, operated as shown in Fig. 2. According to the Provisional Specification the driving rollers may be shifted along their shaft by means of rods within the shaft, the rods being actuated by a crank disc.

Abstract: 655,160. Substation equipment. DAPHNE INVESTMENT TRUST. May 29, 1947, No. 14339. Convention date, March 7. [Class 40 (iv)] In a telephone system in which a calling subscriber can obtain access to a called substation for delivering a recorded message, the record is reversed for as long as the caller pronounces a predetermined vowel, so that a misunderstood portion of the message may be repeated. Ringing current from the calling connection T1 energizes relay R3 to complete a circuit for relay H2 which holds over a contact 18 actuated by a cam geared to rollers To13 carrying the magnetic recording tape. Relay H2 energizes a magnetic coupling Vk15 between the driving motor M6 and the rollers To13 for moving the tape in the forward direction, and also energizes relay N5 which completes a power circuit for the motor. The caller can now hear the message and if, before the cam breaks the holding circuit of H2, he pronounces the predetermined vowel, a slowoperating relay RL27 is energized through a circuit containing a rectifier and inductively coupled to a parallel resonance circuit tuned to respond to a characteristic harmonic of the vowel. Relay RL27 disconnects the coupling Vk15 and connects up a similar coupling Rk14 to drive the tape in reverse for the duration of the vowel.

The track may be laid either horizontally or vertically. When a carriage for transfer is detected the carriage is stopped on the movable points unit 1 and the section of track 25 forming part of the unit, with the carriage thereon is moved transversely into line with the adjacent track 4. The reading device consists of magnetically operated switches mounted on an element 27 adjacent the track on the movable points unit and this co-operates with permanent magnets 23 disposed on the side of the carriage. One magnet 23<SP>1</SP> and one switch act as markers to initiate reading when they are coincident in position. Assume a carriage to be transferred arrives at the movable points unit, on detection by the reading unit, the control unit in turn, reverses the polarity of the supply to the current pick-up rails in an insulated approach section to the points to prevent a following vehicle entering the points section, short circuits the current conductors on the points unit section thus halting the carriage, energizes the conductors of the adjacent track 4 and finally energizes the motor driving the movable points unit on its slide 24 to its other position in line with the adjacent track. Limit switches are actuated when the unit reaches its other position to stop the slide motor and re-energize the pick-up rails on the movable points section so that the carriage moves off to the adjacent track. When a track detector indicates that the carriage has left the points section the slide motor is again energized to return the section to its initial position where further limit switches restore the apparatus to normal.
