MUSIC-BOOK HOLDER AND LEAF-TURNER.

Specification of Letters Patent.

Patented Oct. 10, 1911.

Application filed May 20, 1910. Serial No. 562,474.

To all whom it may concern:

Be it known that we, lVILLIAM H. TRAYER and FRANK CAMPBELL, citizens of the United States, residing at Carlisle, in the county of Cumberland and State of Pennsylvania, have invented new and useful Improvements in Music-Book Holders and Leaf-Turners, of which the following is a specification.

This invention relates to music book holders and leaf turners of that type in which a leaf can be turned over and back again as required, the'musician having merely to press upon a button to effect the turning of the leaf.

The invention has for one of its objects to provide an extremely simple, inexpensive and practical device of this character which stably supports the music book in open position while the second leaf of the music can be freely turned and re-turned without requiring the performer to stop playing.

Another object of the invention is the provision of a novel form of music leaf turning element which consists of members engaging the leaf to be turned at its opposite sides adjacent the binding, said members having laterally projecting transparentarms which extend horizontally across opposite faces of the sheet or leaf at a point intermediate its top and bottom so that as the element turns, the leaf or sheet will turn with it.

Another object of the invention is the provision of a novel arrangement of upstanding members on a supporting base or rest which serve to hold the music book open.

lVith these objects in view and others as will appear as the description proceeds the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claim appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention :--Figure 1 is a perspective view of the apparatus. Fig. 2 is a plan view thereof showing a music book in position, and one leaf thereof at an intermediate position in its turning. Fig. 3 is a longitudinal section of the device showing by dotted lines the book-holding members folded. Fig. 1 is a central transverse section. Fig. 5 is a detail view of the operating means for the leaf turning element. Fig. 6 is an enlarged perspective view of a leaf turning elementwith portions broken away.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawing, A designates the base of the apparatus which may be a strip of wood to form a support or rest for the music book, the under surface of the base being provided with transverse strips 1 of felt so that when the apparatus is placed on a music holder of a piano or organ, it will not scratch or mar the instrument, and also on the base may be provided spring clips 2, whereby the apparatus can be fastened to a music rack. At the center of the base A is a chamber 3 extending from the top to the bottom in which is mounted a frame B that supports the operating means for the leaf-turning element. This means comprises a central vertical shaft 4, which is provided with a pinion or gear 5 that meshes with oppositely disposed rack bars 6 and 7 that slide horizontally in guides 8 on the frame B, and projecting forwardly from the rack bars are stems or rods 9 that pass forwardly through openings 10 in the base and on these rods are push but-- tons 12 arranged side by side. When one push button is in the other is out and while the outer one is pushed inwardly, the other moves outwardly. The shaft 4 projects out of the frame B and has its upper end so constructed as to detachably connect with the leaf turning element C. The frame B is held in the chamber of the base by clips 13 secured to the base and projecting under the frame. On the front edge of the base is a metal piece 14 through which the pushbutton stems extend, and upon removal of this plate and the clips 13, the frame B can be taken out.

The leaf-turning element C consists of two upwardly extending rods 15 which have their lower ends anchored in a base 16 that is in the form of a ring which fits over the projecting end of the shaft 4- and extending diametrically of the ring and secured there to is a key 17 which fits in a slot 18 in the upper end of the shaft 4. It is merely necessary to slip the base member of the leafturning element over the shaft to lock the element thereon, and the removal of the element is correspondingly easy. The upper ends of the rods 15 are bent horizontally to afford connection with transparent arms 19. These arms may be in the form of celluloid or other transparent strips and they are adapted to engage the body portion of the leaf to be turned, and since they are transparent, they will not conceal any of the notes of the music. The leaf to be turned is inserted between the rods or bars 15 which can be sprung apart in adjusting the leaves thereto and the book will be so supported that these rods will be parallel with the binding of the book and as close as possible thereto. Hence, as the element turns on its own axis, it will cause the leaf to turn through 180. For each apparatus, the leaf-turning elements of different heights will be employed for different size music, it being preferable to have the arms 19 engage the leaf near the middle thereof.

In order to support the book in upright position, a plurality of upstanding members or supports are provided on the base A. The covers of the book are adapted to rest against and extend in front of the up wardly extending members 20 disposed a suitable distance apart at opposite sides of the center of the base and in a line behind the leaf-turning element. The lower ends of these members are disposed in sockets 21 in the base and are mounted on horizontal pivots 22 so that these members can fold inwardly toward the center in over-lapping relation so as to take up less room and per mit the device to be folded for transportation. The covers and leaves of the books that are not to be turned are held back by means of short upwardly extending members 23 which are pivoted in a socket 2 1: in the base so as to fold flat against the latter. These members are short so as not to conceal any of the music as they engage the first and fourth pages of the music that is being played. These members 23 are set inwardly near the leaf-turning element, and also forwardly of the rear supporting members 20. The central portion or back of the book is mounted on a central support or rest D which is disposed immediately behind the leaf'turning element. -This support is constructed of a single piece of wire that has its end bent into short upstanding members 24 that engage behind the book and cooperate with the members 20 and 23 to hold the book rigidly in place. The members 24 have horizontal base portions 25 that are connected with a bar portion 26, there being eyes 27 at the ends of the bar for receiving screws 28 that fasten the device D to the base. The intermediate portion of the bar 26 is formed into a forwardly extending central tongue 29 which terminates adjacent the base of the leafturning element, and the bottom edge of the back of the book rests on this tongue. It will thus be obvious from Fig. 2, that two bars or back supports are provided for the book, namely, the members 20 and 24 and single front supports 23. In order to prevent the leaf to be turned from dragging on the top surface of the base, the latter has arcuate ribs 30, on the bottom of which the leaf rides in the turning movement.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention relates, and while we have described the principle of operation of the invention, together with the apparatus which we now consider to be the best embodiment thereof, we desire to have it understood that the apparatus shown is merely illustrative and that such changes may be made when desired as are within the scope of the claim.

Vhat we claim as new and desire to secure by Letters Patent is The combination of a supporting structure for a book, a leaf turning element mounted thereon, and means mounted on the structure to operate the element including a member vertically mounted and slotted at its upper end, said element having abase formed of a ring to detachably fit around the member, a cross key in the ring to engage in the slot of the member, vertical bars anchored at their lower ends in the ring, and leaf-engaging arms on the said bars.

In testimony whereof we affix our signatures in presence of two witnesses.
