Abstract

499,330. Electric switches. COMPTON ORGAN CO., Ltd., J., and BOURN, L. E. A. July 22, 1937, Nos. 20328, 20329, and 20331. [Class 38 (v)] [Also in Group XXXVIII] In an electrical musical instrument wherein the partials of the notes are separately produced, vertical rows of contacts may be operated by the electromagnetic means shown in the Figure. The contacts consist of horizontal silver wires 1 whose free ends pass through apertures in insulating vertical slides 4 and project under bus - bars 2. Depression of a key energizes a magnet 5, the L-shaped armature 8 of which, loosely pivoted at its angle on a rib 13 and controlled by an adjustable screw-head 11, lifts the slide 4 against the action of a spring 10 and allows the wires to make contact with the bus-bars by their own resiliency. The wires 1 are connected to resistances 14 inserted in holes in the board 15. Specifications 403,444, 433,050, [both in Group XXXVIII], and 501,339 are referred to.
