Im rovernents in Music-S ool Mechanisms 'bottom i, key frame 2, find keys 3, supported v of which the following is e specification.

The object of myv invention is to provide simple and efficientmeans to control spindles or, shafts oi the music rolls in automatic musical instruments, to shift the shaft and roll for longitudinal adjustment as required.

My invention comprises novel details ot improvement and. combinations of parte that will be more fully hereinafter set forth and then 'pointed out in the claims.

,Reference is toloe had to the accompanyl ing drawings forming part hereof, wherein,

'Fivure'l is o. front. View ot" e Jertion of n b pieno provided with my4 improvements;

Fig 2 is a partly broken plan View, land Fig. 3 is o side View, partly in section.

I have shown my improvements applied 1n a player pieno having' the customary key in the Diamo cese 4 in usuel manner, the hit-v ter being provided with inusic roll bon 5, e tracker 6, shafts '7,' S, tor the takeup roll 9, shaft ylO ond adjusting device 1l 'for the music roll l2 having the music sheet 13. The shaft l() is mounted to slide in bearings in box 5 in the usual manner, end is provided with the driving sprocket lll, to bey rotated any suitable mechanism. Shaft 10 is normally engaged lo j finger i5 on e.' rock shaft lo journoled in a support l? and operated by crank 18 in e. Well known inenner. CrsnklS is pivotally connected by a link 19 'with o crenlt20 on e vertically disoosed shaft 2 journaled in bearings 22, 23 carried bythe pieno cose. Shaft 2l :it its {ilo'wer end is provided with s crank 2st pir# otolly connected by s rod 25 with o heed or the like 26, in the nature oit` a crank, secured upon e shaft 27.]ournaled in bearings 28, 29 in the key freine. The tore/ard end of shaft 27 in. front of the key freine is provided With-e' handle 230 in position to be convenlently operated. To hold shavia 2f in setA position l have shown 'n spring 3l secured to the key bottoni and bridged across on opening l therein, against which spring head or block 2S hears frictionzrlly :is seid shaft is turned. Tie arrangement. ofv the parts set forth is such that when the handle 30 is in one position, os in the vertical position shown in Fig. l, the devices that connect said handle with the crank 1S retain shaft 10 ine position to support ond rotate the inusic roll 12 by the interposed coupling l0n of any well-known construction. it shaft l0 is to be adjusted in one direction or the other 'the handle will be correspondingly rocked, and by the connections 'from said handle to crank 18, the. iinger l5 will ybe rocked to cause shaft l0 to be shifted the required amount to adjust the music spool with respect to the tracker, in order to maintain .perfect registration of the perfor-ations in the music sheet 'with the orifices in the trzrcker, and the ports will bc retained in set position by spring 3l bearing cgeinst head or block 26.

Having now described my invention what l cla-im is l. The combination of a musical instrunient having keys and o key traine, music roll supporting,` mechanism provided with o. shaft having ineens to connect with n music roll, o finger to cenet with seid shaft to nuove it longitudinally, o crenk erin connected 'with seid finger, o vertically disposed sheift carried by the musical instrinnent und connected with said crunk erin, e horizontal rod connected with seid shalt to rock the latter.
