iy 51 1/02 whom i? m foznel o ami Woman l i back plate is a stub shaft 32 carrying at its cured on said stub shart, the pawl levers 3e forward or free end, the wheel 33 provided with outwardly extending teeth 34 and forwardly projecting teeth 35. Between said wheel and said baclr plate pivotally seand 37 carrying pawls 38 near their upper ends and c unt-er balances 39 at their lower ends.

The pawls 38 engage h outwardly e2 tending teeth throughout a portion of the movement of the levers 36 and 37 but are held from engagement with said teeth near the upper end of said movement by means of an are shaped plate 40 secured to said back plate. Near the upper ends of said levers are wires 41 adapted to connect with pedals 42 and 43 secured to the lower end of said standard 1. The lever 37 carries its upper end a forwardly curved piece havi therein an eye adapted to receive therein a curved rod d5 fastened to the outer -nd of the pawl 46 pivot-ally secured to the outer end of a smaller lever 47 pivotall mounted upon a pin 48, rotatably mounted in a bearing 49 in said back plate and a bearing in a front plate 50 secured to the front of said tubular support 8 and on which said arms 7 are pivotally mounted. The pin 48 carries a rigid wheel 51 and the pinion 52 adapted to engage the teeth 16 to i love said rod 13 upwardly when the smaller lever $7 is oscil-- lated. A box 53 may be provided to contain the mechanism thus described.

The upper end of the rod 13 is provided with a cross bar 5 carrying on the same side as is the eye and the cur ed. rod 5, a

short (low wardly projecting wire 55 passing through a perforation 56 in the plate 2% and passing forward of any of the ar 1is 25 pointing to the s side. The opposite end of the bar 54 is provided with a U-shaped wire 57 having its free 58 shorter than the long 59 which is secure-d to the end of the bar 54, said long passing through alined perforations 60 in the plates 19 and 20, the tree arm 58 projecting upwardly in front of certain of the ar its 25 when the arnts are pointing on said side.

The operation of this device is as follows: The :iusic book being open d and placed upon the board 5 has placed between the leaves, a series of fingers 27 and arms 25 all pointing on the e and 45, the fingers of the lows turned first and placed behim which are to be turned, the lug ceived by the slot of the is this position the wire 55 w' wardiy in front of all of the is except the lowest one. ith the parts this position, when it is desired to turn the leaf, all that is necessary is to press upon the pedal Tl i lever 37 to force i e leaves v. 1 rod 13 the l eaus aroi

arizis disl; 26 by means of t next leaf is to be turi c pressed. '1. his pressure cans s of the lever t war er causing 'oer a 'nga tne lever and tl rotate the piniof into the slot r ent of the lever engage the wheel o r ation of the lug 30 a plate to rotate turn the other lei.- tinued, each operatic- -g1stern1g slo each ness 0'; one dis on that side 'lro'xi-a l'oii hen the leaves are t j is operation is (or i nuniber of leaves ha: i t r it is desired turn the is other way, the lever 413 is p thus ca sing the wheel 33 to rotate H oppos'tc direction H5 eusing the in the direction opposite the direction above deer bed. in

each case the leg will carry itl'OulG the non-registering slot 28 to registewlth the slot yist above 1t. 'Jne action of gra will cause the r i the lower slot; untll the desir r tion, a support, rod passing through said support, a plurality of disks provided with perforations by 'J-Qeans of which said disks are pivotally mounted upon 1. in con said rod, fingers secured to aid disks, said 8 disl-(s being provided with radially extending slots co unicating with said perforations, a lug on said rod adapted to engage any one ol. the slots, rotate said rod, means for raising said rod. to place the lug in engage ent with the succeeding dish, and to prevent the rotation of certain of said dislts when one of said disl-fs is being rotated in either direction.

2. in combination, a support, a rod passing through said support, a plurality of dish: provided with pe 'iorations by reans ol which said disks are pivotally ounted upon said. rod, lingers secured to said disks, said dislis being provided with radially extending slots co; runicating with said perforations, a lug on said rod adapt-ed to engage any one of said slots, eans to rotate said rod, eans l'or raising said rod whereby any one of said say be selected, rile-ans to return said slots ro unicating wit 1 said perforations,

a log on said rod ed to en age any one i ol said slots, rot ting ans to rotate said rod, and iuieans 'l'or aisn said rod whereby any one ol' said slots ay be selected, said ro tating neans coreprising pinion on'said rod a wheel having teeth adapted to said p rion a mi an osrillating pawl adapted to en age said teeth, and positive 7 eans to re l'roiu a it More than one oi said did-1s turning Ll11.;l.
