Abstract

1361582 Screw and nut gearing MeCORD CORP 10 May 1972 [16 Aug 1971] 21824/72 Heading F2Q In an arrangement wherein a screw-threaded shaft 14 is moved axially up or down (as viewed in Fig. 4) on rotation of a shaft 24 of an electric motor 22 in one direction or the other respectively, but is free to be moved manually when the motor is stopped, arms 50, 48, swung by centrifugal force, having weights 66 at their ends and pivoted to a rotatable member 32 splined to the shaft 24 each carry a half nut 44 and a half nut 46 on a V-shaped portion 54, 56 respectively, nuts 44 engaging the shaft 14 when the motor is rotated one way to swing the arms 48, 50 in one direction and so move shaft 14 downwards) the condition shown), the other half nuts, 46, engaging shaft 14 to screw it upwards when the motor rotates in the opposite direction (and consequently the arms swing the other way). With the motor 22 stopped the arms 48, 50 hang vertically, with neither pair of half nuts engaging the screw-thread 26 on shaft 14. Portions 28 and 30 of shaft 14 limit the axial movement thereof. The invention is described in relation to the remote operation of safety catches in car doors.
