The speed of a motor is regulated by connecting it to a mechanically oscillating device which resonates at a critical speed and so restrains the motor by the increased loses. In its simplest form, Fig. 1, the motor 2 drives a load 15 and also a magnetized disc 1 which interacts with a similarly magnetized disc 4 suspended for axial resonance on springs 5 or by leaf springs 5<SP>1</SP>. If desired, the disc 4 may be fixed by a bearing 5<SP>11</SP> so that it can only execute rotary oscillations, in which case discs 1 may be placed on each side of disc 4. If desired, the mounting 6 of the springs 5 may be made resiliently rotatable and arranged to operate a rheostat controlling the driving motor to maintain it at a speed somewhat below the critical speed. In a modification, the magnet 1 is of cylindrical form and the vibrating element comprises a magnetized ring coaxial with it and sprung to reciprocate axially. In the form shown in Fig. 5, the speed of the motor 2 is controlled by a rheostat 25 operated through a differential gear 17, 22, 23 by any deviation of the motor speed from the resonant speed of a disc 19 with respect to the vibrating disc 20. Specifications 708,127, 745,911 and 747,724 are referred to.

Title: An improved wheel suspension for motor vehicles
IPC: B60K17/30
Filed: 1926-09-01
Abstract: 265,084. Fornaca, G. Sept. 1, 1926. Springs, arrangement of.-In a suspension for steering or combined steering and driving wheels, the steering pin of each wheel swivel rotates and slides axially in a cylinder pivoted to a rigid framework comprising a mud-guard bracket and transverse support for the lamps, the swivel being connected by a ball joint to an inextensible arm on the chassis. The suspension spring may con. stitute the inextensible arm, or the arm may be a rigid rod pivoted to the chassis, in which case a helical spring enclosed in the cylinder serves as the suspension spring. The application to driven steering-wheels is shown. The stub-axle 6 is carried by a casing 7 which encloses the universal joint of the driving shaft 2 and carries the steering pin 8. The, casing 7 is ball-jointed at 9 to a transverse spring 18 secured to the frame 19, the leaves of the spring tapering in width from the frame to the wheel. The pin 8 carries a plunger 10 which slides and rotates in a cylinder 11 pivoted at 12 to the mudguard bracket 13 and lamp support 14. The plunger 10 divides the cylinder into two chambers 11<1>, 11<2> connected by apertures 17 and a passage 16 in the pin 8. The cylinder contains air and liquid, and, owing to the effective cross-sectional area of the chamber 11<2> being smaller than that of 11<1>, the air above the liquid is compressed when the pin slides into the cylinder. In a modification, the spring 18 is replaced by a rigid V-shaped member pivoted at the ends of its arms to the chassis, and a helical spring is mounted in the upper part of the cylinder which carries a rod and plunger sliding in a second cylindrical member which constitutes the steering pin and forms the dashpot chambers.
