Abstract: 1,043,901. Expanding-wheel gear. L. H. D. M. BALLU. Jan. 20, 1964, No. 2397/64. Heading F2D. A double-expanding wheel gear for independently driving the wheels or tracks of a motor-vehicle for ratio-shift and enforced differential action for steering comprises input or output expanding pulleys 2, 3 having inner flanges 4, 5 fast on a hollow shaft 1 and outer flanges 6, 7 axially movable thereon under control of centrifugal balls 25 or rollers arranged between the movable flange 7 and a dished plate C secured to a central rod 9 carrying at its outer end a manual control unit 10 formed by two opposed helix members constituting an extendable bush 12 which bears on the movable flange 6. The arrangement is such that the centrifugal balls vary the effective pulley diameter for step-up or down ratios, and may be overriden by the unit 10 which comprises two manually-operated controls 13 and 14 respectively connected one to each of the opposed halves of the bush 12. The control 13 operates to relatively rotate the helix members to increase or decrease the length of the bush 12, the former closing the flanges of the pulleys 2, 3 providing a step-up or overdrive ratio, whilst the latter, which may be caused by the vehicle foot brake, serves to separate the pulley flanges to provide a step-down ratio for braking &c. The control 14 may be connected to the vehicle steering gear and operates to axially bodily move the bush 12 to vary the pulley diameters, relative to each other, to cause differential action of tracks or wheels. A single control may be used for both enforced differential steering and ratio shift. In Fig. 2 (not shown), centrifugal rollers are mounted on pivotable arms at the end of the hollow spindle between the control unit and the adjacent movable flange on which the rollers engage, the unit being formed as two levers operated in a scissor-like action reducing or increasing the effective length of the centre connecting rod to uniformly change both pulley diameters for step-up or down ratios, or, axially moved as before, to vary the pulley diameters for a differential action.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 5, 1933]. [Classes 35 and 38 (ii).] Motors with unwound iron armatures.-An electromagnet a, Fig. 2, is provided with a primary winding 1 connected to an alternating current supply and a secondary winding 2 which when loaded, e.g. by short circuiting at the contact c, causes a sufficient increase in the stray flux between the windings to attract an armature b ; in the form shown in Fig. 7, the armature b completes the magnetic circuit of the magnet a and is released when the coil 2 is short circuited. A further modification includes a pivoted armature with a limb in each of the armature positions shown in Figs. 2 and 7. The magnet may impart a continuous vibration to the armature which may constitute or carry a sound emitting diaphragm, or the hammer of an electric bell. A vibrating contact may be included in the circuit of the secondary coil. It is stated that the coils may be placed on a common arm or on divided arms and they may be disposed one above the other. A stationary iron member may be placed between the coils. The apparatus may be used as a transformer supplying a low voltage, for example 20 volts, and a tertiary coil may be disposed in such a position to prevent actuation of the armature during such use of the magnet. The tertiary coil may be connected to the primary or secondary coil. Pole shoes may be provided, for example by stamping the laminµ, and such shoes may carry an auxiliary winding supplied by the secondary coil. In order that the magnet may be used in connection with toys, the apparatus is formed with suitable holes. The term armature is stated to include rays, electrons and discharges. Fig. 5 shows the invention applied to a motor, the circuit of the secondary coil being periodically interrupted at c due to the rotation of the pole wheel b. The rotor b may have a winding supplied from the secondary coil 2, and this winding may be tapped.
