IPC: B60Q1/44
Filed: 1971-12-09
Abstract: 1375557 Centrifugal switches DANA CORP 9 Dec 1971 [8 March 1971] 57323/71 Heading H1N A speed-responsive switch mechanism comprises a sleeve 60 axially movable on a rotatable shaft 16 by means of a governor mechanism and with a spring 66 arranged to resist the axial movement, and a switch 72 having a pivoted operating lever 94 urged towards shaft 16 to engage mutually co-operating cam surfaces on the lever and sleeve, so arranged that the force on the lever is resolved dominantly as a compressive force in the lever which resists axial movement of the sleeve, and subordinately as a force acting to rotate the lever against bias imposed by the switch, the lever being free to ride on an axially-extending surface of the sleeve, upon disengagement of said cam surfaces, without imposing significant frictional restraint to axial movement of the sleeve 60 in either axial direction. As shown, weights 46 pivoted at 56 on brackets 52, 54 secured to shaft 16 urge sleeve 60 to the left by means of bell crank arms 58 against the restraint of a blade spring 66 carried by the sleeve 60 and of operating lever 94 pivoted at 96 on a microswitch 72. The cam surface 100 on sleeve 60 is preferably at 45 degrees to the shaft 16 and the end of lever 94 is bent to provide a cam follower at less than 45 degrees to the shaft axis. The force exerted by spring 66 is adjustable by a set screw 70, and switch 72 is mounted on a bracket 84 having a resilient portion 82 whereby the position of switch 72, and thus lever 94, can be adjusted by a screw 90. The arrangement deliberately emphasises the differential between the speeds of shaft 16 at which switch 72 will be opened and closed and the device finds particular application in a motor vehicle where the part 14 of a two-part casing 12, 14 is fitted into a gear-box casing 30, for example, interposed in the speedometer cable connection. Oil seals 32 and 38 are provided, and apertures 42 allow transmission fluid to serve as a lubricant for the switch.

Title: Magnetic reed contact devices
IPC: H01H50/54
Filed: 1971-12-10
Abstract: 1373225 Magnetic reed contact units FUJITSU Ltd 10 Dec 1971 [11 Dec 1970] 57609/71 Heading H1N In order to ensure that the contacts of a sealed magnetic reed contact unit open and close at substantially the same flux values, the main air gap is arranged to change in area rather than length. Fig. 4, shows the ends of two reeds 41, 43 normally out of alignment with an air gap t between them. When subjected to a magnetic field the reeds 41, 43 tend to align and bring non-magnetic contacts 42, 44 into engagement. The contact gap X 2  is less than the normal displacement between the centres of the reed ends so that member 42 which is of spring material bends to give a wiping action. The member 42 may be cranked to provide a larger contact gap (Fig. 5b, not shown), or may be an integral part 822 of a reed 812 (Fig. 8d). Thus providing a part which is directly overlapping the other contact and also provides a variable air gap. The contact end may be divided (Fig. 8e, not shown).
