Abstract: 1,038,797. Spool driving arrangements. AKAI ELECTRIC CO. Ltd. Sept. 15, 1964 [Sept. 16, 1963], No. 37556/64. Heading G5R. An arrangement for driving a spool carrier 22 at a fast speed by the engagement of a wheel 21 with the larger cone of a driving pulley assembly 24 and at normal speed by the engagement of a wheel 17 with the smaller cone of assembly 24, is characterized in that the wheels 17 and 21 are tightly coupled by spring means during fast wind and less tightly coupled when winding at normal speed. The spring means 18, Fig. 4, is in the form of a disc provided with grooves 18a and 18b and with a central projection 18d which engages a groove 16b in a sleeve 16 rigidly attached to the wheel 17. A felt ring 19 on the spring co-operates with a friction ring 20 formed on the lower surface of wheel 21; this allows some slip when wheel 17 is driven so that the spool may be driven faster than a capstan drive to provide tape tension. For fast drive a collar 15 is raised by manually operable means (not shown) thereby raising the wheel 17 within the wheel 21 and compressing the spring 18. The driving cone assembly 24 may be slidable in a horizontal plane or pivotable in a vertical plane to engage either wheel 17 or wheel 21 for normal or fast drive.
