Abstract
741,038. Mounting electric motors. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 22, 1954 [Dec. 24, 1953], No. 35834/53. Class 35. [Also in Groups XXIV and XXXVIII] An electric motor drives a fly-wheel which is so shaped and arranged that the motor lies wholly or partly within the fly-wheel so that the latter functions as a magnetic screen for the motor. Fig. 1 shows a driving motor 1 having a cup-shaped fly-wheel 10 of magnetic material on a shaft 7 arranged to drive a magnetic soundrecording apparatus. Fig. 2 shows the coupling arrangement between the motor shaft 7 and the recording tape driven spindle 15. The shaft 7 is secured to the fly-wheel 10 through a bush 11. A rubber cylinder 19 having two pairs of holes 20 couples the spindle 15 to the fly-wheel when a pair of pins 17 of the spindle 15 and a pair of pins 18 of the bush 11 are inserted into the holes 20. The spindle 15 is passed through a semi-cylindrical recess 24 in a bearing 23 mounted in a housing 25. The latter has a cut-out 28 for the exposed part of the spindle 15 so that the latter may frictionally drive a slidable wheel 32. If the spindle 15 is replaced by another spindle having a greater diameter and placed in another wider recess 24a, a higher tape speed is achieved. The tape itself is frictionally driven between a free-wheel 29 and the wheel 32 as in Fig. 3 (not shown) and means-being provided for guiding the tape towards and away from the wheel 32. Specification 696,650, [Group XXXVIII], is referred to.
