Abstract
1285555 Pickup housings PLESSEY CO Ltd 13 Oct 1969 [12 July 1968] 33509/68 Heading H4J A snap-action two-part shell for the transducer element 6 of a gramophone pick-up cartridge has one part 2 provided with projecting portions 15, 21 at each end. One end of the other part 1 has a shoulder 18a adapted to be engaged by a tab 11 of the portion 15. When engaged, pivotal movement of part 2 relative to part 1 permits engagement of a locking portion 22 of the part 2 with a shoulder 26 of end part 25. The shoulder 26 may be inclined (28a) to cooperate with a corresponding surface 22b. The two parts, when closed, abut along their lengths at surfaces 3, 3a and 4, 4a. One, preferably both, parts 1, 2 are of resilient plastics material such as polypropylene or nylon. The two parts 1, 2 define a cavity for two piezo-electric elements 6 clamped at one end and engaging a coupler 7 near the other end. The coupler 7 engages a stylus arm 8 held in a recess 9. A handle 10 permits either of two styli 11, 12 to be in operative position.
