Abstract
A stop tablet mechanism particularly suited for electric organs wherein a plurality of stop tablets lie in closely spaced apart side-by-side relation, the stop tablets being pivotally supported on a tablet rail and spring-biased to assume a neutral position from which they can be momentarily moved up or down against the action of the spring.
Claims5
A stop tablet mechanism for electronic organs or the like, comprising,
- a supporting bracket having a plurality of parallel spaced-apart elongated flanges, each having an opening therethrough substantially aligned with the openings in the others, and having a plurality of attaching means positioned one each between adjacent ones of said flanges and spaced from the alignment axis of the openings in said flanges,
- an elongated rod received and supported in the openings in said flanges,
- a plurality of elongated stop tablets each having upper and under surfaces, one positioned between each adjacent pair of said flanges, and each having a transverse groove in its upper surface near one end thereof engaging said elongated rod for pivotal movement thereabout, and having a curved portion on its under surface extending from said one end to a point substantially opposite said groove, and
- a plurality of elongated flat springs, one for each of said stop tablets, each secured at one end to a respective one of said attaching means with said one end lying substantially in a plane including said elongated rod, its other end being free and engaging the said curved portion of the under surface of said stop tablet, that portion of the spring engaging the stop tablet having a radius of curvature substantially conforming to said curved portion of the tablet thereby to urge the bottom of said groove into engagement with said elongated rod and to maintain said stop tablet in a predetermined neutral position, and operative to return the stop tablet to said neutral position from alternate positions of use displaced from said neutral position.
