MUSIC-LEAF TURNER.

Application filed July 14,

This invention relates to what is known in the art as a music leaf turner and the embodiment herein shown and described has more particular reference to a device of this class which is more especially designed for turning the loose leaf in sheet music such as is employed in piano playing.

' As is well known, the ordinary sheet music embodies a cover page on the inner side of which a portion of the musical notation appears, usually the preliminary part of the verse; a back sheet containing the concluding part of the score, and the finale, and a loose leaf on opposite pages of which the remainder of the composition is scored.

In playing this class of music, the performer is compelled to turn the loose leaf back and forth when repetitions of the verse are required. As beforestated, the present leaf turner is expressly designed for use in connection with this character of music, although it may be slightly varied for turning'a multiplicity of sheets such as is used in orchestrations.

Briefly, it comprises a rack which is stationary, a single leaf turner which is mounted for swinging movement thereon, a foot pedal, and an operating connection between the foot pedal and the leaf turner.

The alleged novelty is based upon the novel arrangement and association of parts, which cooperate to produce a specifically new structure.

In the drawings dinary piano equipped with the device.

Fig. 2 is a bottom plan view of the device removed.

Fig. 3 is a vertical section through a portion of the rack.

Fig.4 is an enlarged fragmentary detail and sectional elevational view of the lower Figure ,1 is a front elevation of an or-' 1927. Serial No. 205,734.

and rising vertically from the base member are vertical backing bars 9 fastened at their upper ends to a horizontal top member 10. Supporting and foot blocks 11 are fas toned to said base member 8, one of the blocks being represented in Fig. 6.

Incidentally, the block is of the shape shown, and preferably provided with a tapered end carrying a rubber buffer 12.

Rockably or swingably supported on the rack is the leaf turner generally designated by the reference character 13. This is in the form of a wire member which includes a vertical shaft 14 mounted for oscillation in suitable guide holes formed in the top and base members of the frame.

The lower end of the shaft 14. is formed to provide a crank 15 and the upper end is formed to provide an offset angularly disposed arm 16 which is equipped with resilient grips 1.7 constructed to engage the loose leaf (not shown) of the sheet music. As shown in Fig. 2, a link 18 is connected to the crank arm and extends through an opening formed in one of the blocks 11'.

A coiled spring 19 is connected to this link and anchored on the rack as shown in Fig. 2. This serves to return the turner to a normal position as shown in Fig. 1. Connected to the link is a pull cord 20 which extends down over a small pulley 21, fastened on the outer bifurcated end of an extension member 22. As represented in Fig. 4, this member 22 is fastened by suitable means to one of the blocks 11. Also if desired, it may be formed intermediate its ends with a spacer and rest 23.

In considering Fig. 4, it will be noted that one end portion of the aforesaid link 18 is turned upwardly as indicated at 24 to insure smooth operation of the pull cord.

Considering again Fig. 1, it will be noticed that the pull cord extends down over a sec ond pulley 25 then down over a third pulley 2o, carried by a right angular bracket. Finally, it is connected with a pivotally 1nounted foot pedal 27 carried by a suitably anchored base plate 28.

The pedal is located within convenient operating distance of the performers foot. In practice, the sheet of music (not shown) is placed upon the ledge 8 of the rack in an obvious manner and the spring clips are engaged with'the central or loose leaf, the back sheet and cover page being spread open ready for playing. leaf, is placedagainst the back sheet in the usual manner. However, When the end of the notationon the bottom of the page (usually page 2) is reached, the operator places his foot upon the pedal-27 and presses downwardly, swinging the turner over in. a

direction from right to left through an approximate half circle and turning the sheet over to expose the notation 'on the next page.

The operator-must hold his footon the pedal to hold this pageover, While'it is being played,=:and also -;Wl1 ile the notation on the, back page is being read. However; when therend of the compositionis reached, and a repeat is necessary, the foot is removed "trom- V the pedal a ndthe spring serves to return the sheet, to the normal relationshin.
