What I claim is:

1. A device of the llnd described comprising acasing, a non-rotary spindle extended through said casing, anda plurality of key carriers independently mounted directly on said non-rotary spindle and provided at their extended portions with means for holding and carrying keys, the said key carriers having projecting arms adapting them to be independently manipulated from the y invention here;

` the exterior of the casing, said key carriers each `"comprising a pair of spring plates wardly pressed trunnion-iorming portions fen` having ingageable in holes in the head of the keys.

2. In a device of the kind described,a casing, a common spindle extended Within said casing, anda plurality of` key carriers independently pivoted on said common spindle and having projeoting arms adapting them to be independently manipulated, said key carriers further having radially projecting key holders engageable with the heads of the keys at points remote from the axis of said spindle and adapted to carry the keys bodily on the arc of a circle, the axis of which is the axis of said spindle.

3. The structure defined in claim 2 in which said key holders, remote from the axis of said spindle, have bosses adapted to engage seats in the heads of the keys.

4. In a device of the kind described, a casing, a common spindle extended within said casing, and a plurality of key carriers independently pivoted on said common spindle, said carriers having projecting arms adapting them to be independently moved pivotally on said spindle, sai/df carriers further having projecting arms equipped with means located oiset of the axis pf' said spindle and operative Vto independently/and detachably hold the respective keys projected from the axis of the spindle and with the keys located entirely outward of the axis of the spindle.

5. In a device of the kind described, a casing, a. common spindle extended within said casing, and a plurality of key carriers independently pivoted on said common spindle and having .projecting armsadapting them to be independently manipulated, said key carriers further having spring-acting key clamping elements adapted by friction to hold the respective keys projecting radially from the axis of said spindle and for' movement of said keys bodily around the axis of said spindle when the respective key carriers are moved on the axis of said spindle.
