To m7] whom it may concern.-

Be it known that we, MIOHEAL A. ZIELINSKI and ANTHONY M. PEKAREK, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is .a specification.

This invention relates to improvements in an apparatus to be used for turning the leaves of music, either when in book form or what is known as sheet form; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of our invention is to provide amusic-leaf turner which shall be simple and inexpensive in construction, strong, durable, and effective in operation, and which shall be so made that its parts may be detached and folded into a small or compact form for convenience in carrying same.

Another object of the invention is to provide means so that when one of the leaves has been turned and it is desired to repeat the music said leaf may be turned back to its original position, from whence it may again be turned, after which the remaining leaves may be turned and reversed, if desired.

A further object of the invention is ,to so construct the device that its parts may be readily assembled, easily detached, or adjusted to the proper height to suit the user.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which our invention pertains to make and use the same, we will now proceed to describe it, referring to the accompanying drawings, in which- Figure 1 is a front view in elevation of a music-leaf turner embodying our invention, showing the parts in their normal positions ready for use. Fig. 2 is an enlarged view, partly in section and partly in elevation, of the upper portion of the supporting-standard and a part of theframe for the music, the upper plate of said frame being omitted. Fig. 3 is a longitudinal sectional view of a portion of the supporting-standard. Fig. 4 is a sectional view taken on line 4: 4 of Fig. 1 looking in the direction indicated by the arrows.

Fig. 5 is a rear view of the music-frame, showing a portion of the supporting-standard and illustrating the turning-arms and mechanism for operating the same in their normal or initial positions. Fig. 6 is a similar view of like parts, but showing one of the turningarms as having been turned. Fig. 7 is a fragmental plan view of the music holder or frame, showing the turning-arms in their'normal positions. Fig. 8 is a similar view of like parts with the turning-arms in a position corresponding to that shown in Fig. 6; and Fig. 9 is a view in front elevation of a portion of the music holder or frame, showing it in its collapsed position and illustrating an indicator thereon for a guide in properly placing the music-sheets.

Like numerals of reference refer to corresponding parts throughout the different views of the drawings.

The reference-numeral 15 designates the main tube of the supporting-standard, which has on its upper end an enlargement 16, in which is located a set-screw 17, used for adjustably holding the upper section or portion 18 of the standard which fits in the tube 15 in place. In order to shorten the portion 18, it is provided in its lower end with a circular plug 19, which projects beyond its end to engage a detachable piece 20, which may be removed when desired. The supporting-standard is held in an upright position by means of a series of legs 21, which are pivotally secured at their upper ends to a ring 22, slidably mounted on the tube 15. Pivotally connected at one of their ends to the lower portion of the tube 15 are bars 23, the other ends of which are similarly connected to the legs 21 at about their middle, so that said legs and bars may be folded to said tube. Pivotally secured on the lower portion of the tube 15 are pedals 2st and 25, to be used for operating the turning-arms, as will be presently explained. The upper portion of the upper section of the supporting-standard is bent rearwardly, as shown in Fig. 2 of the drawings, in order to give the desired inclination to the music-leaf holder or frame, which is detachably connected to the supporting-standard.

The holder or frame for the music consists of upper and lower plates 26 and 27, respectively, each of which is angular in cross-section-that is to say, the upper plate is provided with a forwardly-extending flange 26,

while the lower plate is provided with a forwardly-extending flange 27, as will be readily understood by reference to Figs. 2, 7 to 9, inclusive, of the drawings. These plates are connected together near their ends by means of bars 28 and 29, which are pivotally united at their inner ends, as well as being pivotally connected to-"said plates at their outer ends. The rear portion of the upper plate 26 is provided at its middle with an upwardly-tapered socket 30, which is preferably formed by pieces 31, secured to said plate, and is for the reception and retention of the upper end of a bar 32, which forms part of the music-holder and has on its rear surface near its lower end circular clips 32 and 33 for the reception of the deflected portion of the supporting-standard. The clip 33 has on its upper end an inturned portion 34 to act as a adjustably holding another bar 39 in place on the front surface of the bar 32, as is clearly shown in Figs. 1 and 40f the drawings. The lower plate 27 is provided at its middle and on its rear surface with clasps 40 to engage the lower end of the bar 39, and said clasps are by preference formed integral with the said plate by being punched out and rearwardly offset. The bar 39 is held in alinement with the bar 32 by means of pins 41, located on tle front surface of the bar 32, near the lever 38 thereon. The forwardly'extending flange 26 of the upper plate is provided at its middle with a forwardly-projecting extension 42, on which are pivotally secured, by means of a pivot 43, a series of arms 45, 46, and 47, each of which has on its pivoted end a segmental gear 48 to mesh with or engage the gear-teeth of the rack- bars 49, 50, and 51, there being one rackbar employed for each of the turning-arms. These rack-bars are located on one another and are movably held on the flange 26 of the upper plate by means of bolts 52, which pass through a longitudinal slot 53 in said flange. Near one of its ends the rack-bar 49 or the upper one is provided with a downturned bracket 54, which earriesaheaded pin or screw 55' to engage a slot 56 in one end of an arm 57, which is pivoted at its other end to a shifting bar or lever 58, which bar is pivotally connected at its other end to the rear surface of the bar 32, as is clearly shown in Figs. 5 and 6 of the drawings. Pivotally connected to the bar 58 at about its middle are arms 59 and 60, which are checked in their downward movements by means of stops 61 on the rear surface of the bar 58. Connected at one of its ends to the outer end of the arm 59 is a connection 36 such as a cord, chain, or other flexible articlethe other end of which is connected to the pedal 24, and connected at one of its ends to the outer end of the arm is a similar connection 37, which is united at its other end to the pedal 25, and, as shown in Figs. 1 and 5 of the drawings, these connections pass through the rings 35 on the lower portion of the bar 32, which forms a part of the music holder or frame. Each of the turning-arms is preferably formed by having its edges upturned throughout most of its length, as shown in the drawings, and is provided near its free end with a downwardly-projecting clamp 62 of any desired construction to clasp the sheet of music, so that when the arm is turned on its pivot it will carry the sheet therewith.

In order to properly position the sheets of music, the plate 26 of the music-holder is provided with a cut or pointed indicator 63 at its middle, which should register with the middle of the sheets when they are in place on the holder.

From the foregoing and by reference to the drawings it will be readily understood and clearly seen that the gear-teeth of the rackbars are arranged in groups, which groups are spaced apart so that only one of the turningarms will be moved at the same time and that as the rack-bars are bolted together they will move in unison.

The operation is simple and as follows: When the parts are assembled as shown in Figs. 1, 5, and 6 of the drawings, it is apparent that the plates 26 and 27 may be suitably adjusted with respect to one another hyturning the cam-lever 38 in the proper position to allow the bar 39 to slide thereunder,when said bar may be firmly secured by again turning the said lever in the proper direction to press the same against the bar 32, which supports the upper plate of the music-holder. When these plates are suitably adjusted, the music is placed in position so that its bottom edges will rest on the forwardly-extending flange 27 of the lower plate, while its top edges will lie directly under the flange 26 of the upper plate. By engaging the clamps 62 on the turningarms with the different sheets of music and by pressing down on the pedal 25 it is evident that the upper turning-arm 45 will be turned from the position shown in Figs. 1 and 7 to that shown in Figs. 6 and 8, in which operation the sheet held by its clamp will also be turned. If it is desired to turn said arm and sheet back to their original positions, it is only necessary to apply pressure to the pedal 24, which through its connections with the rack-bars will cause the said turningarm and the sheet to which it is connected to be turned back. The same operation may be repeated for turning each of the turning-arms, and it Wlll be understood that while we have shown three turning-arms and a corresponding number of rack-bars, yet we do not desire to be limited to this number, as We may employ one or more of each of said elements without departing from the spirit of our invention. It is also obvious that the rack-bars may be actuated by levers instead of the pedals, which levers may be suitably located, so as to be operated by the hand or knee. As the connections 36 and 37 are secured to the outer ends of the arms 59 and 60, it is manifest that by applying pressure to either of said connections the lever 58 will be moved in the proper direction and through its connection 57 with the bracket 5 L on the rack-bars Will cause the latter to be slid back and forth on the flange of the top plate, in which operation the segmental gears 48 on the pivoted ends of the turning-arms will engage the gear-teeth on their respective rack-bars. When it is desired to fold the parts, the connections 36 and 37 may be detached from the pedals, after which the music holder or frame may be removed from the supporting-standard and the bar 32 removed from its socket 30, when the upper and lower plates of the holder may be folded together, as shown in Fig. 9 of the drawings. As the arms 59 and 60 and the bar 57 are pivotally connected to the lever 58, it is apparent they may be folded closely together. By loosening the set-screw 17 on the main tube 15 of the supporting-standard the section 18 thereof may be removed and the portion 20 detached, so as to render said section shorter. The supporting-legs 21 of the standard may be folded thereto in the well-known manner.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A music-leaf turner, comprising a musicholder consisting of an upper and lower flanged plate, bars pivotally connected together at their inner ends and to said plates at their outer ends, the upper plate having on its rear surface at its middle a socket, the lower plate having at its middle clasps, a bar adapted to fit at its upper end in said socket and having on its lower rear portion clips and on its front portion pins arranged in vertical alinement, a cam-lever on the front lower portion of said bar, a supplemental bar located at its lower end in the clasps on the lower plate and adapted to be pressed against the other bar by the cam-lever thereon, and a supporting-standard to fit in said clips, a turningarm horizontally pivoted on the upper plate and having a gear on its pivoted end, a rack-bar engaging said gear and movably mounted on the upper plate, a shifting bar pivotallysecured at one of its ends to the music-holder, a link pivoted to the other end of said bar and to the rack-bar, oppositely-extending arms secured to the shifting bar at about its middle. and a connection united to each of said oppositely-extending arms to move said bar so as to reciprocate the rack-bar, substantially as described.
