UNXTED STATES JAMES W. GRIMSLEY, OF W'ASI-EINGTON, DESTRICT OE' CGT'LJ'MBIA.

MUSIC-TURNER.

To all whom it' may concern:

Be it known that I, ,Mams W. Gnmsnnr, a citizen of the United States, residing at Vfashington, in the District of Columbia, have invented certain new and useful Eniproveinents in liiusic-Turners, of which the following is a specication.

This invention relates to music turners, and more particularly to such devices adapted for detachable engagement either with a piano or for incorporation upon music stands.

lt has for an object the provision of a novel foot operating means for turning leaves, which is positive and silent in operation.

Another object. is to provide such a device by means of which leaves may be turned forwardly or backwardly at will without readjustment of the machine between such operations.

A further object is to provide such a mechanism whereby any number of leaves may be turned successively forwardly or backwardly as may be desired.

A particular object of the invention is to provide a novel construction of actuating mechanism for the turning of the leaves.

Other objects and advantages will be apparent from the following description, and itl will be understood that changes in the specific structure shown and described may be made within the scope of the claims, and Yhat any suitable materials may be used without departing from the spirit of the invention.

In the drawings forming a portion of this specification. and in which like numerals of reference indicate similar parts in the several views, Figure l is a front view of the device in initial position. Fig. 2 is a bottom view of the device, the music clamp being shown in inoperative position. Fig. 3 is an edge view of the device, the clamp being shown in operative position. F el is a fragmentary vertical sectional view of the device through the operating mechanism. F 5 is a fragmentaryr perspective view of the operating mechanism in initial position.

Referring to the drawings, there is shown a supporting framework comprising a base member l0 carrying a central pivot rod ll and a plurality of uprights l2 and l2', the uprights l2 being disposed to the rear of those 12. lt will be understood that as many uprights may be utilized as desired, or other Specicaton of Letters Patent.

Serial No. 476,712.

l suitable modifications in the framework l made. The uprights 1Q are engaged with an upper cross piece 13 extending the full width of the turner, and the ugrights i2 are connected by cross pieces la spaced on opposite sides of the turner, and secured in rigid spaced relation with the piece 13 in any suitable manner. Engaged upon the uprights and pivot rod there is a vertically slidable framework B, having suitable guide members l5 engaged with the uprights and provioed with suitable fastening means 16 arranged to engage the pivot rod ll to secure the' framework adjustably at various points in its movement. Carried in vertical slidable engagement with the framework B there is a vertically adjustable music support C adapted to support the leaves of a music book in open position when placed upon the support C. rEhe support C is provided centrally with an upwardly extending resilient clamp 20, comprising a rod having its lower end pivoted to the base of the support C and provided with a downwardly extending yoke Q1, its outer portion being bent inwardly over the support C and extended vertically thereabove for resilient engagement centrally of sheets of music or music books to retain them firmly upon the support. rlhe upper end of the clamp 2O is bent outwardly to facilitate the engagement of music thereunder as will be subsequently described.

Carried centrally of the framework B there is a vertical sleeve engaged slidably over the central rod ll. Engaged revolubly and slidably upon the rod l1 and resting revolubly upon the upper end of the sleeve there is a plurality of telescoped sleeves 26, 27, 28, and 29, respectively, though it will be understood that. as many such sleeves as desirable may be utilized. lt will be noted that the inner sleeves are greater in length than the outer ones, the length of the intermediate sleeves being graduated therebetween, and at their lower ends each sleeve carries a horizontal disk portion 8O having a pendant flange 31 at its periphery, the disks being so graduated in size that the flange of each projects downwardly below the edge of the tiange of the next disk thereabove.

Each of the flanges 3l is cut away on one side leaving an enlargement A extending as shown approximately for a distance equal to 7/17 of its circumference and forming shoulders 82 and 34 at its ends. The shoulder of the inner sleeve is square, as shown, and the shoulder on each successive outer sleeve is increased in height, a. distance equal to the height of the first shoulder. Each of the shoulders of the disks, inwardly of the outer one, is provided with an inclined guide portion 32 ext-ending outwardly therefrom beginning at a point equal to the height of the next inner shoulder, and leaving a vertical portion 34 for a purpose to be subsequently indicated. Suitable washers may be interposed between the disks 30, if desired, to facilitate the relative rotation of the sleeves 26 to 29 inclusive which occurs during the operation of the device.

rlwo helical springs 35 and 35 are disposed around the sleeve 25 and secured at their bases against rotation. spring is somewhat heavier than the inner one. Engaged revolubly around the sleeve 25 at its upper end, there is a collar 36 carrying a reverse operating arm 37. The collar 36 is supported upon and engaged by the inner spring' 35 to hold it yieldably at the upper limit of its movement in engagement with the flanges 31, and against outward rotation. Engaged revolubly around the collar 36, there is another collar 33, carrying a similar forward turning arm 39 supported upon and engaged by the spring 35 to hold the arms 39 yieldably against the flanges 31 and against inward rotation. Each of the arms 37 and 39 is provided wit-h downwardly projecting wrist pins 41 receiving thereover levers 42 connected intermediately of levers 43 carried by the frame B, and pivoted inwardly of the ends of the links 42 and laterally thereof as shown. -Connected to the outer ends of the levers 43, there are connecting rods 44 connected to pistons 45 carried in suitable cylinders 46 secured to the framework B and suitably connected at their ends with flexible pipes 48 for the transmission of pneumatic or other fluid pressure to the piston 45 within the cylinder. Preferably such operation is accomplished by two pedal operated bellows which may be of any suitable type and should be disposed at a convenient point for engagement by the operatrs feet. As the construction of this bellows forms no essential portion of the invention, and as it is be* lieved that it is 'not essential to show their operation, these are not illustrated in the drawings.

It will be noted that each of the links 42 is provided with an outwardly extending arcuate portion cent-rally thereof, and upon communication of pressure to the piston, the arms 37 and 39 will be operated, the arcuate portions of t-he links 42 engaging outwardly of the springs 35 and 36 and allowing the movement of the arms to their full limit oppositely of the piston.

At their upper ends the sleeves 26 to 29 The outer inclusive, are provided with horizontal arms 50 provided at their outer ends with pendant engaging clips 51, all adapted to rotate in independent arcs, the clips shown comprising resiliently spaced arms 52 adapted to be engaged oppositely with the respective leaves of music to be turned.

In use, the framework B is adjusted at a height to bring the arms 50 to a point near that at which it is desired to dispose the top edges of the music to be turned, and the platform C is adjusted at the proper height to engage the lower edge of the music. The book or sheets of music may then be opened, and the clamp 2O engaged therewith at the pivotal point of the leaves, after which the clips 51 are engaged respectively with the separate leaves. lt will be noted that in initial position, the shoulders 32 are all disposed at the rear side of the turner, and the shoulders 34 at the forward side and upon actuation of the arm 39 by means of communication of pressure to the proper cylinder 46, the inclined portion 32 of the inner member A will engage the arm and guide it downwardly beyond lall of the flanges except the inner one, the vertical shoulder portion 34 of which it will engage to rotate the respective sleeve 26, and the arm 50 thus turning the first page of the music. If it should be desired to turn the page back again, the opposite arm 37 may be operated, which will engage the opposite shoulder of the flange ina similar manner for reverse movement of the leaf. 1f the leaf is not reversed, a second operation of the arm 39 will engage the next to the outer flange 31 in a similar manner and so on, each operation turning a new sheet. t will be seen that the arms 37 and 39 will be returned to their initial position after each operation by means of the springs 35 and 35.

Carried at opposite sides of the support portion C, there are two engaging clamps 54 adapted to be engaged with the cover of a book, or pages that are not to be turned to retain these against casual movement by the suction created by turning of the leaves or otherwise. For adjustment of the movable framework B upon the central rod of the apparatus, there is a yieldable clamp member 16 of any suitable type adapted to engage the central rod to support the framework B at any point in its movement.

The support C is provided with a vertical sleeve 55 engaged slidably over the lower end of a rod 18 carried by the frame B and having a lock bolt 56 for securing the support at different points in its vertical movement.

The rod 2O is held yieldably in vertical position by means of a suit-able spring G having a recessed portion adapted to snap over a rounded hump 57 formed in the rod outwardly of its pivot point.
