Abstract

1531874 Damped springs LENCO AG 5 April 1976 [19 Feb 1976] 13636/76 Heading F2S [Also in Division G5] A resilient support member for mounting a gramophone chassis 11 on a base 12 comprises a spring 3 having the movement of part of its length damped by a piston 10 moving in a sleeve 21. The spring 3 is threaded at one end over an extension 9 of a member 20 mounted on the base 12 and engages at its other end a bush 4 attached to one end of the piston 10 which is connected at its other end to the chassis 11. The sleeve 21, which has its inner surface coated with a temperature stable silicon grease which damps movement of the piston therein, is mounted by means of a disc 22 between the ends of the spring whereby part 3b of the spring is damped to reduce low frequency vibration leaving part 3a undamped to oppose higher frequency vibration. Horizontal vibrations are damped by sleeve 21 rubbing on the piston as the disc 22 tilts.
