MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented July 1, 1919.

Application filed March 18, 1918. Serial No. 223,100.

To all whom it may concern Be it known that I, JOHN G. REED, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Music-Leaf Turners, of whichthe following is a specification.

This invention relates to an improved music leaf turner and has for its primary object to provide such a means which may be easily mounted or attached to the body of a piano, organ, or other similar body or structure, and convenientlyoperated by the player without in any manner interfering with the players operation of the instrument.

Another important object of the invention is to provide such a leaf turningdevice, for turning the leaves of. sheet or book music which can be operated by the players foot without removing the foot from the instruments pedal.

It is also another important object of the invention to provide va music leaf turning device which may be applied to a piano or organ and that the actuating means may be mounted within the structure of the musical instrument without interfering with the operation of its mechanical parts and without marring the artistic beauty of the instrument.

Yet another important object of the in vention is to provide such a device for turning the music sheets detachable from its actuating means and may be removed from the piano or organ when not in use.

And it is a further general object of my invention to provide a device as above characterized, which is highly serviceable and convenient in practical use, consists of relatively few parts of simple form, and which may, therefore, be applied to pianos, organs, or to other bodies or structures where the device may be used for a similar purpose at a comparatively small cost.

. With the above and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed. and illustrated in the accompanying drawings, in which: i

F lgure 1 is a front elevation of apiano case and showing the leaf turning device applied, i

Fig. 2 is a vertical section view, partly broken away, taken at right angles to Fig. 1 in the plane of the supporting sleeve for the leaf turning pin,

Fig. 3 is a detail perspective view of the sheet turning element and its associated p Fig. 4c is a horizontal section on the line H of Fig. 2,

Figs. 5, 6, 7 and 8 are detail perspective views of certain of the parts.

I have in the accompanying drawings shown a piano case for the application of my invention, and which I generally designate by the numeral 5. Itis however, tobe understood, that the device may be mounted in any other structure or bod in an desired manner for a similar use an that t erefore, the invention is not to be limited by the present illustration. Referring to the drawings, in detail, 6 indicates an L-shaped lever, preferably of metal. This lever has its long arm fulcrumed intermediate its ends at 6 in the frame of the piano case 5, adjacent the pedal 7, and has near its outer end extending at right angles and in spaced relation to the piano frame, the foot plates 8 and 9. The foot plate 9 is off-set as at 9 to extend under the pedal to the relatively opposite side thereof where it terminates in an upstanding lug 9. The plate 8 has a similar terminal lug 8 located at the other side of the foot pedal.

The L-shaped lever 6 is further provided on the end of its short arm with an upstanding pin 10. A rod 11 is vertically mounted for turning movements in the straps 12 and has a collar 13 on its upper end to prevent its upward movement. An arm 14 projecting at right angles to the rod 11 and secured thereto prevents the downward movement of the rod, 15 designates a stop plate fixed to the base of the piano case for engagement by the arm 14 to limit the turning movement of the rod 11 in one direction. The arm 14 has the slot 16 to receive the pin 10. The upper end of the rod 11 has the laterally projecting rod or finger 17 which is provided with an angularl bent downwardly projecting terminal 1 Abell crank lever 18 is pivoted to the under side of desk board 19 as at 20, and said bell crank lever having the arms 21 and 22 disposed at right angles to each other and each provided with a longitudinal slot 23 and 24 respectively. The

slot 23 in the arm 21 slidingly accommodates the terminal 17 of the finger 17 on the rod 11. A short pin 25 having on its one end, the downwardly projecting finger 26 and in its other end the central slot or kerf 27. This pin extends through the opening 28 in the desk board 19 and is seated for turning movement on the metal strip 29 attached to the desk board 1.9. This pin is free for turning movement and its finger 26 slidingly engages in the slot 24: provided in the arm 22,

In mounting the rod 11 an opening is provided in the keys as shown at 30. This permits the rod to turn freely and without interfering with the operation of the keys. Also to hold the pin 25 in position, an artistic-ally designed guide plate is mounted on the top of the desk board 19 as shown at 31.

The detachable music rack and sheet turning member includes the sleeve or tube 32 having the arcuate slot 33 in spaced relation to its lower end. In the tube, free for turning movement, is the rod 3%, said rod being provided with an arm 35 extending through the slot 33. A rectangular lug 36 is provided on the lower end of the rod 34: adapted for detachable engagement in the slot 27 in the pin On the arm 35 a sleeve 4-1 is frictionally engaged and is adapted to be longitudinally adjusted. Upon this sleeve the sheet receiving clip 37 is pivotally mounted as at 38. This clip may be of any suitable form, but is preferably so constructed that it will not tightly clamp the music sheet but permit of the free movement of the sheet through the clip. A second clip indicated at 39 is also fixed upon the rod or arm 35, and inwardly of the latter clip. The arm 35 is provided with a pivot joint as shown at 40. I also provide the arms 41 and at one of their ends with supports 42 for holding sheet or book music. These arms are pivotally attached at their other ends to the sleeve or tube 32 as at 43 and adapted to fold parallel with the sleeve or tube.

It will also be seen from the above description that the clip 37 may be folded into parallel relation with the arm 35 and that this clip is folded at the point 38 into parallelism with the sleeve 32 and the folded arm 35.

In assembling the music sheet rack and turning arm in operative position with the actuating mechanism, the lower end of the sleeve 32 is inserted downwardly through the central opening in the plate 31 and the squared lower end of the rod 34 is engaged in the slot or kerf 27 whereby the rod 341 and the part 25 are coupled for rotation as a unit. The arms al on the sleeve 32 and the arm 35 carried by the rod 34am then moved outwardly and downwardly to horizontal positions and the pivoted clip 37 raised to a vertical position. By shifting the sleeve 44:

this clip may be adjusted to receive the lower edge of the left hand music sheetadjacent the outer vertical edge thereof, while the clip 39 receives the music sheet at a point adjacent its inner edge. The covers for the sheet music are preferably seated upon the supports $2 on the outer ends of the pivoted arms 41.

In the operation of my improved sheet turning device as above described the player may shift the L-shaped lever 6 to the right or left by engaging the upwardly projecting ends of the foot plates 8 and 9" with the toe and shifting the L-shaped lever 6 either to the right or left. The movement of said lever in one direction being limited by the engagement of the lever arm 22 with a part of the piano case structure. The movement of the lever 6 in the opposite direction is limited by engagement of the arm 14 with the stop plate 15. Either movement of the L-shaped lever 6 causes a relative movement of the rod 11 which actuates the bell crank lever 18 and thereby affects the rotation of the part 25 through the co-action of the lever 24 on the finger 26. The rod 3 1 being coupled to the part 25 is thus rotated in the sleeve 32 and the arm '35 connected to the lower end of the saidrod is swung from left to right or vice versa, as the case may be, whereby the musicsheet engaged in the clips 37 and 39 is turned.

The device operates very easily and needs only a slight pressure from the foot of the player against the projecting ends of the foot plates 8 and 9 and thereby shifting the L-shaped lever on its pivot whereby the sheet or leaf turning member is operated as above described. The toeof the players shoe may be used for this purpose without removing or lifting the foot from the floor by simply pivoting the heel on the pedal and turning the toe to either side thus pressingagainst either of the projecting foot plates 8 or9 depending upon the direction in which the foot is turned.

From the foregoing description, taken in connection with the accompanying drawings, the construction, manner of operation, and several advantages of the invention will be clearly and fully understood. It is to be borne in mind, however, that these features of the device are susceptible of many mechanical variations and may be embodied in numerous alternative forms. Therefore, while I have shown and described what I at present believe to be the best embodiment of the invention, it is to be understood that I expressly reserve the privilege of adapting all such legitimate modifications as maybe freely embodied within the spirit and scope of the invention.

I claim:

The combination with a musical instrument including a tone modifying pedal; of

a music leaf turner including a ivoted lever arm pivotally supported upon the instrusupported laterally of the peda a plate atment and means connecting the terminal of tached to the lever provided with vertically the lever with the turning arm.
