Abstract

433,298. Motor driving-arrangements. STAPLETON, A. W., 186, The Avenue, HATFIELD, R. H., 34, Clevedon Road, and LAWLER, R., 191, The Avenue, both in Highams Park, London. Jan. 13, 1934, No. 1336. Drawings to Specification. [Class 35] [See also Group XL] In a wireless receiver wherein tuning is effected automatically, the tuning controls are driven by a motor through a clutch. The clutch may be operated by the motor armature which may be slidable longitudinally and into and out of its field. Thus when the motor is energized the armature is moved longitudinally to engage the clutch and when switched off reverse movement takes place under spring control to disengage the clutch.
