'Music-HOLDER.

SPECIFICATION forming part of Letters Patent No. 718,091, dated January 13, 1903. Application filed April 28, 1902. Serial No. 104,958. (No model.)

To au whom, t may concern:

Be it known that I, JAMES N. CHADwIoK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Music-Holders, (Case No. 1,) of which the following is a full, clear, concise, and exact description.

Myinvention relates to a music-holder; and its object is to provide imp roved mechanism whereby leaves of sheet-music may be automatically turned whenever desired by the mere actuation of a key or trigger by the performer.

I will describe my invention particularly by reference to the accompanying drawings, which illustrate the preferred embodiment thereof, and the features or combinations which I regard as new will be pointed out in the appended claims.

Figure lis a perspective View of my improved holder, showing the music held in position and the device set or adjusted so that the leaves may be turned one after another by pressing the corresponding keys. Fig. 2 is a front elevation. Fig. 3 is a detail view of one of the clips by which the outer sheets or covers of the m'usic are fastened to the frame of the holder. Fig. Ll is a detail side view of an adjustable hook by which the framework of the holder may be secured to the ordinary music-rack of a piano. Fig. 5 is a detail elevation of the upper portion of the holder, illustrating the mounting of the three turning-arms. Fig. 6 is a plan view of the parts shown in Fig. 5. Fig. 7 is a detail front view of the mechanism which rotates the shafts which carry the turning-arms. Fig. 8 is a bottom view of said mechanism. Fig. 9 is a detail cross-sectional view of the bottom of the rack on line 9 9 of Fig. 7, and Fig. 10 is a detail view of one of the clips carried by the turning-arms.

The same letters of reference are used to designate the same parts wherever they are shown.

The framework a, which may be secured to the ordinary music-rack of a piano either by simply resting thereon or by the adjustable hooks ct a', is provided with spring-actuated clips a2 a2, near the top on either side, which Aserve to bind the outer sheets or covers of the music against the face of the frame. The intermediate leaves of the music which require to be turned may be held in spring-clips b b b2, which are carried upon the turning-arms c c c2, respectively. The clips d2 are preferably of the form shown in Fig. 3, and the clips b b b2 may be constructed as shown in Fig. 10. I preferably provide the jaws of the clips with facings x, of rubber or similar material, to prevent the leaves of music held thereby from slipping or tearing. The adjustable hooks d' may be provided with rubber sleeves d3 to prevent them from marring the rack with which they are engaged.

The arms c c c2 are carried by shafts d d d2, respectively, projecting radially therefrom. The central shaft d is pivoted at the top and bottom in cone-bearings, the lower end of the shaft being pointed to rest in the conical depression in the lugf, whilethe upper end of said shaft is pivoted upon the point of a screw e, which is fastened in a suitable lug or standard a. The two shafts d d2 are tubular, the intermediate shaft d being journaled upon the shaft d and the other tube or shaft d2 being journaled upon the intermediate shaft d. Either of these shafts may be turned independent of the others to swing the corresponding turning arm carried thereby.

The mechanism for rotating the shafts to swing the turning-arms is shown in detail in Figs. 7, S, and 9. Pinions g g g2 are mounted upon the lower ends of the shafts cl d d2, respectively, and sliding rack-bars h h h2 are arranged to mesh with said pinions to rotate the same. Either of the arms c c c2 may thus be moved by sliding the corresponding rack-bar to rotate the pinion meshing therewith. Each rack-bar slides in suitable bearings, and said bars are fastened to'sliding rods/7712, respectively, which slideI to and fro with said rack-bars. The said rods are encircled by compression-springs Vk 7o' k2, which are confined between an abutment 164 and adjustable nuts upon the ends of said rods. The rack-bar h2 is provided with an extension h3, which is turned up at the end to form the thu mb-piece h4,whereby the rackbar may be manually reciprocated. The ra ck- IOO bars h and h/ are provided with lugs or rightangled extensions h5 h6, respectively. The lug h6 projects into the path of the end of the rack-bar h2, while the lug h5 projects into the path of the lug h6. The result is that when the upper rack-bar 712 is moved to the right, Fig. 7, the other rack-bars 7i and 7L will be carried along with it, so that all three pinions g g' g2 will be rotated together in a direction to swing the turning-arms from left to right. Each rack bar is L-shaped in cross-section, the rack being cut in one of the projecting edges, while the other edge is provided with a notch Z, which is adapted to be engaged by a trigger or detent, whereby the rack-bar may be held in its right-hand position against the tension of the spring. Three keys m m m2 are provided for controlling the release of the rack-bars h 72, h2, respectively. The said keys are mounted upon the ends of the spring-Shanks 'n n 'm2, respectively, which are fastened at the rear to the framework and press against the lower edges of the rack-bars in position to slip into and engage the notches Z in said bars. Each of the keys when depressed disengages its shank from the notch in the corresponding rack-bar and permits such bar to be moved back to its normal position by the spring.

A lug 0 is provided upon the frame of the operating mechanism in opposition to the thumb-piece h4, so that the thumb-piece and the several rack-bars controlled thereby may readily be moved by grasping the parts h4 and 0 with the thumb and finger and pressing the thu rnb-piece h4 toward the lug 0.

The operation of the device is as follows: The several clips a2 a2 and b b b2 are first opened and the music placed on the rack or framework a. The covers or outer sheets of the music are then fastened by the clips a2 a2, which bind said sheets against the framework. The intermediate sheets are then fastened in the clips b b b2, which are, carried upon the turning-arms. I have shown three turning-arms to accommodate three intermediate sheets; but it is obvious that a musicholder may be provided with any desired number of turning-arms within reasonable limits, such modifications as might be necessary being such as would readily suggest themselves to any one skilled in the art. The music being fastened by the clips the thumb-piece 71,4 is moved to the right, whereby the three rackbars h 7L h2 are also moved to the right, rotating the pinions g g g2, and so swinging the turning-arms to a right-hand position, as shown in Fig. l. When it is desired to turn the rst sheet of the music, the performer has only to touch the key m2. This will disengage the trigger n2 from the notch in the rackbar h2, -sothat said bar will be released and will be moved back to the normal position by the spring k2. As said bar moves the pinion g2 isvrotated thereby and the shaft d2 turned, so that the arm c2, carrying the iirst sheet of the music, is swung from right to left, the

music being thus turned automatically. In like manner the other intermediate sheets of m usic may be turned by touching successively the other keys. When desired to repeat, as is frequently the case, the performer can swing all the turning-arms back to the right by pressing upon the thumb-piece h4. In this manner the music may be manipulated rapidly and with great ease. It will be observed that the keys and controlling mechanism are all placed at the bottom of the rack, where they will be instantly accessible to the performer.

It will be apparent that modifications may be made in my invention and that the ideas herein set forth may be embodied in structures differing somewhat widely as to their particular construction without departing from the spirit of my invention, and I do not, therefore, desire to be understood as limiting myself to the precise apparatus shown in the drawings; but,

Having thus described the preferred embodiment of my invention, I claim as new, and desire to secure by Letters Patent, the following:

l. In a music-holder, the combination with the frame, of a number of vertical tubular shafts mounted concentrically in the central portion of the frame and adapted to rotate independent of one another, a turning-arm mounted at the top of each shaft and carrying a clip adapted to hold a sheet of music, a pinion carried by each shaft, racks meshing with said pinions to rotate the same, a spring connected with said racks tending to move the same in a direction to swing the turningarms from right to left, a piece h4 connected with one of said racks adapted to be grasped to move said rack in a direction to swing the corresponding turning-arm to the right, lugs carried by the racks for engaging one another, whereby the other racks are carried along with the one which is actuated, to swing all the turning-arms together to the right, and detents holding the several rack-bars independently in the right-hand position and adapted independently to release the same.

2. In a music-holder, the combination with the frame, of a number of vertical tubular shafts mounted concentrically in the central portion of the vframe and adapted to rotate independent of one another, a turning-arm fastened to each shaft and projecting radially therefrom, each arm carrying a clip adapted to hold a sheet of music, a pinion carried by each shaft at the lower end thereof, sliding rack-bars meshing with said pinions and adapted to rotate the same to swing the corresponding shaft and turning-arm, springs connected with said rack-bars and tending to move the same in a direction to swing the turning-arms from right to left, mechanism for moving the several rack-bars simultaneously against the tension of said springs to swing all the turning-arms to the right, and triggers or detents holding the several rack-bars in the position IOO IIO

to which they have been moved, each of said In Witness whereof I hereunto subscribe detents being adapted to be actuated indemy name this 26th day of April, A.
