17,757. Dow, A., and Bennett, J. July. 26. Music spools and rollers; winding-mechanism. -The music roller A is provided with a loose flange B1, and is hinged to the spindle E', so that it can be disengaged from its loose flange and turned outwards to enable a fresh music spool to.be fitted on to it. The flange B1 is fast on the driving-shaft E and is normally engaged by a projection k on the roller A. The flange B is attached to the roller A, which has an extension c1 on which a disk C fits. The disk C is held in position by a nut and is hinged to a boss D, which is fast on the spring - pressed holder E'. By pushing the roller A sideways against the action of the spring e, the roller may be disengaged from the flange B' and turned outwards for a new music spool to be fitted. A projection on the music spool engages a groove in the roller A. Two modifications are described in which the roller A is dispensed with, the spool being held between projections provided on the two flanges,
