Abstract
238,989. Cranidge, J. M. June 23, 1924. Addition to 208, 718. Bell-operating mechanism, hand and foot; bell strikers. - Bell-mechanism, similar to that described in the parent Specification but adapted for hand or foot operation, comprises a pivoted striker-arm 9 carrying abutment lugs 12, 13 and normally resting in its retracted position by reason of a spring 14 or its own weight, the spring clapper 11 engaging the bell 6 by reason of its momentum when the lug 13 engages the case plate 8. For hand operation, the arm 9 may be provided with a knob 15 or with an upwardlyextending arm fitted with a knob or with an attachment for a cord &c. For foot operation, a guided pedal may act on the knob 15 or directly on the arm 9 as shown in Fig. 5. The bell 6 may occupy either position shown in Fig. 5, or, in a further modification, the hammer may be disposed inside the bell. Specification 11446/90 is referred to.
