Filed: 1951-07-03
Abstract: 705,419. Controlling change-speed gearing. MASSAROTTI, M. July 3, 1951 [May 21, 1951], No. 15742/51. Class 80 (2) Gears are automatically pre-selected by a speed-responsive governor (not shown) acting through rod 106 and lever 104 on a cam bar 10<SP>1</SP> slidable longitudinally on guide pins 100, the engaged gear is disengaged on depression of the clutch pedal 70<SP>1</SP> and the pre-selected gear is engaged on the return movement of the pedal. Cams on one side of bar 10<SP>1</SP> operate a spring- loaded lever 16<SP>1</SP> connected through balanced springs 132 and rod 128 to an arm 126 on a shaft carrying a gear quadrant 122 engaging rack teeth on a rotatable disc 50<SP>1</SP> secured on a shaft. In the different axial positions of the latter, an arm 24<SP>1</SP> thereon engages one or other of three gearchange rods 120. Cams on the other side of bar 10<SP>1</SP> operate a spring-loaded lever 28<SP>1</SP> connected through balanced springs. 136 and rod 134 to a member 34', the lower end of which is pivoted to one arm of a bell-crank lever 146, the other arm of which is connected, through a lost motion device 150, 154 and rod 58<SP>1</SP>, to the pedal 70<SP>1</SP>. The upper end of member 34<SP>1</SP> co-operates with a pair of stop pins 88<SP>1</SP>, and the member 34' has recesses 142, 144 co-operating with pins 11.2, 114 on disc 50<SP>1</SP>. A manual lever 78<SP>1</SP>, co-operating with a notch M' on the pivot hub of lever 104, is provided for positioning bar 10' for reverse, neutral and forward drive, bar 10<SP>1</SP> having pairs of cams for reverse, neutral and four forward speeds. Fig. 1 shows the gear set at neutral, by lever 78', with the pedal 70' depressed, while Fig. 3 shows the position of the parts with fourth speed both pre-selected and engaged. The lost-motion device, comprising balls 160, Fig. 5, in holes in the wall of a hollow cylinder 154 connected to lever 146 and co-operating with annular grooves 158, 156 in a fixed guide sleeve 150 and in rod 58<SP>1</SP> enables the clutch to be disengaged before lever 146 is moved anti-clockwise from the position of Fig. 3, thus moving member 34' downwards and causing disc 50<SP>1</SP> to turn clockwise, since recess 144 is engaged with pin 114. This turning of disc 50<SP>1</SP>, and hence of arm 24<SP>1</SP>, causes the engaged fourth gear to be disengaged, enabling arm 24' to make the pre-selected axial movement. On releasing pedal 70<SP>1</SP>, lever 146 moves back clockwise before the clutch is engaged, causing member 34' to be moved upwards and producing rotation of disc 50<SP>1</SP> in . the pre-selected direction. and hence the engagement of the automatically pre-selected gear. An auxiliary spring 162 acts on lever 146 in such a way that it is ineffective when the pedal 70' is fully depressed but augments the clutch springs when the pedal is released. The pedal may be operated automatically by a servomotor controlled by the pre-selecting means. Specification 668,951 is referred to.

Title: Improvements in magnetic motors
IPC: H02K25/00
Filed: 1929-05-28
Abstract: 331,340. Worthington, H. L. May 28, 1929. Rotary machines.-A motor has a rotor and stator each comprising permanent magnets arranged to repel each other normally and provided with moving magnetic members or depolarizers arranged so as (i) to move into the polar regions of the stator magnets and deprive them of external polarity as the rotor magnets approach them, thus creating an attraction between the fixed and moving systems, and (ii) subsequently to move away from the polar regions of the stator magnets as the motor magnets recede from them, thus allowing the normal repulsion between the two sets of poles to maintain the rotation. In the form shown, the depolarizing members consist of rollers actuated by solenoids which are energized from an external source in turn by the rotation of the armature. The stator consists of pairs of horseshoe magnets 8 carried in a non-magnetic frame 7 and the rotor comprises similar magnets 6, the polarities being as indicated in Fig. 2. Each pair of stator magnet rows is associated with two rollers 9 pivoted in movable bridges 12 and adapted, by means of solenoids 14, 15 and core links 18, 19, to be moved from the full line to the dotted line position shown at the top of Fig. 1. In the full-line position the poles 8<A>, 6<A> repel each other and the magnetically short-circuited poles 8<B> with the rollers 9 attract the poles 6A. A clockwise movement is thus given to the rotor until the poles 6<A> are coaxial with the poles 8<B>, as shown in dotted lines, and brushes 36 on the rotor move to the next segments of a fixed commutator 32 and deenergize the solenoids 14 and energize the solenoids 15 from a generator 21 or battery. This rocks the rollers to the position shown in dotted lines and the ensuing repulsion between the poles 6<A>, 8<B> maintains the rotation. The rollers 9 travel along the radial surfaces of the stator poles and in their non-short-circuited positions they are lifted away from the poles by non-magnetic cam surfaces 37 formed on the frame 7. The commutator-may be adjusted angularly by means of a stop 33 and holes 34 in the fixed hub for controlling the speed of the machine or for reversing its rotation. The outer magnets may alternatively rotate about fixed inner magnets or the depolarizers 9 may be applied to the rotor magnets instead of to those of the stator.
