Abstract

1300154 Endless tape cassettes T CREUTZER 13 March 1970 12880/70 Heading G5R An endless tape cassette has a lockable ball bearing 4 whose outer ring 1 carries at 3 a tape support 5 having a removable core 7 with a concave periphery, a cap (24, Fig. 8, not shown) covering the support. In use, the core 7 is screwed or otherwise attached (Figs. 9, 10, not shown) to the support 5 and the assembly is located on the carrier 3, a cover-plate 14 placed over the inner ring 2 and the bearing locked by inserting a pin 11 into the outer ring 1 and against spring clip 13 holding the tearing rings 1, 2 together, The free end of a tape reel is held by a spring 8 around the core 7 and a few turns wound on manually. The assembly is placed on the takeup spool carrier of a conventional tape recorder and the required amount of tape wound on, possibly making a recording at the same time. The tape is cut and the takeup assembly dismantled to enable the spring 8 to be removed, thereby providing a clearance between the tape and core 7, and the tape ends to be joined together. The unit is reassembled without the spring 8 and pin 11 but with the cap (24) held on to the inner ring 2 by a spring (27, Figs. 14, 15, not shown). The cassette may then be used on the supply spool carrier of the tape recorder, and may be stored without the cap 24, but with an elastic band passing over the tape and engaging in notches in the support 5.
