Abstract

1419469 Electrophonic musical instruments WURLITZER CO 20 Feb 1974 3587/75 Divided out of 1419468 Heading G5J A keyboard for an electrophonic organ comprises key assemblies consisting of octave groups made up of three key groups 56a, 56b, 56c, each key group being a one-piece plastics member comprising a mounting strip 60a, 60b or 60c to which the keys 62a, 62b or 62c are joined along a zone of reduced thickness formed by a notch 68a, 68b or 68c acting as a hinge, the notch 68c being on the opposite surface to the other notches and the mounting strips 68a, 68c being vertically displaced so that the notches are approximately in line when assembled, effectively forming a common hinge axis for all the keys. The keys are downwardly open hollow structures each including a switch actuator 66a, 66b or 66c and a finger 64a, 64b or 64c which hooks under a flange 46 (Fig. 5, not shown) in the key bed to limit the upward movement of the keys. The key bed and other features of the electrophonic organ are as described in Specification 1,419,468.
