JOSEPH M. DUPLANTI, OF dELLEVUE, PENNSYLVANIA.
MUSIC-LEAF TURNER.
SPECIFICATION forming part of Letters Patent No. 660,630, dated October 30, 1900 Application filed February 6, 1900. Serial No. 152. 'lo mode-Li To all whom it may concern:
Be it known that I, JosnPH M. DUPLANTI, a citizen of the United States, residing at Bellev ue, in the county of Allegheny and State of Pennsylvania, have in vented certain new and usefulImprovements in Music-Leaf Turners; and Ido declare thefollowingto beafull,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw ings, and to the figures of reference marked thereomwhich form a part of this specification.
This invention relates to certain new and useful improvements in music-leaf turners.
The object of my invention is to provide a simple,practical,and usefuldevice forquickly turning the leaves of sheetnnusic. The device is particularly adapted for use upon the piano or organ, but may be used upon a tripod for other instruments.
\Vith the above object in view the invention finally consists in the novel construction, combination, and arrangement of parts, as will be hereinafter fully described in detail.
In describing the invention in detail reference is had to the accompanying drawings, wherein like detail parts in the several views are designated by numerals of like character.
In said views, Figure 1 is a front elevation of my improved m usic-leaf turner. Fig. 2 is a side elevation of the same, showing the case in section. Fig. is a plan view of the case containing a portion of the mechanism. Fig. 4 is a perspective view of the rod for supporting the leaf-turning frames. Fig. 5 is a perspective view of the catch for turning the leaf-frames. Fig.6isasectionalviewthrough the supporting-rod on the line X X of Fig. 1.
In the drawings the numeral 1 designates a rectangular case having a removable lid 2, secured to its upper side, and the downwardlyprojecting tube 3, secured fast to the under side. Within this case and upon a pin 4: is pivoted the segmental gear-rack 5, which ongages with a pinion 6. This gear-rack is held in its normal position against the stop-pin 7 by means of the coil-spring 8. To the opposite side of the gear-rack is attached a chain 8', which passes over a pulley 9, thence down the tube, and connects to a key-lever 10, which is pivotally attached by one end to the bracket 11. Aslightly-inelined rod l2,havinga square shoulder formed at its lo er end, is fitted into openings 13 in the case. This rod is provided near its lower end with a collar 14: and projection 15. A suitable n umberof wire frames 16, having eyes formed on their ends, are loosely fitted upon said rod. The eyes of these frames are not entirely closed, but are made open sufficieut to engage over and slide down the projection 15 into a position of rest upon the collar 14 when said frames are in rned to the left. In order to prevent the frames from moving too far on either side, a pair of stops 17 is provided and attached to the lid of the case. Extending at an angle from the shaft 18 of the pinion is the rod 19, having a hooked catch 20 at one end to engage the frames at the left and turn the same when desired.
In order to hold the sheet-music in place upon the rod, I employ a Wire 21 to engage in eyelets 22 in such manner that the musicsheets will be clamped to the rod by the wire. The music-leaves being clamped in position to the rod, as previously described, and in such manner that the back of each sheet will rest upon a frame, the frames and leaves are all turned to the right. When the frames and leaves are turned to the right, the hooked catch 20 will engage with the first frame, as shown in Figs. 1 and 2. The device being now in condition for use in turning the leaves, the operator simply presses downward upon the key or trigger 10 when it is desired to turn a leaf. Thepressing of this key communicates a rotary movement to the pnion, and as the catch 20 is in engagement with whatever frame is next to be turned the pressing of the key will cause the frame to be thrown over to the left, and in consequence turn the leaf. Vhen the frame is turned to the left, it will drop down and look upon the projection 15 of the rod, as shown in Figs. 1 and 6. When one frame is turned to the left, the balance of the frames will slide down the rod, so that the next frame will be in position to engage with the hooked catch when saidcatch returns to its normal position upon the release of the key or trigger. As
each frame is turned to the left and looked as described, the next frame will drop down into the position of engagement previously occupied by its predecessor until all frames are turned to the left by pressing the key. When it is desired to restore the frames to their former position upon the right, the frames are all raised upwardly suflicient to disengage the eyes with the projection upon the rod. They may then be easily restored to their former positions at the right.
It may be stated that the movement of the segmental gear-rack is limited by the pins 23 and 7, as a full rotation of the pinion is not required to throw over the frames.
Slight modifications of the detail parts enteringinto the construction of the device may be made without departing from the principles involved.
Having thus fully shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is
I. In a device of the class described, the combination with an upright rod to engage the musicleaves and the wire leaf-turning frames having eyes formed upon their ends to engage over said rod, of a means of supporting said rods in operative position and locking the same when position is reversed,
which consists of a projection such as 15 upon the rod and the partially-formed eyes on the I lower portion of the frames, as shown and set forth.
2. In a device of the class described, the combination of a rectangular box adapted to form a base-piece, a slightlydnclined rod or shaft secured upon the upper side of said case, wire frames loosely mounted upon said rod, a gear-pinion mounted within said box upon an independent shaft having one end projecting up through said box, a rod secured to the projecting end of said shaft and extending ont therefrom, a hook-catch secured upon the end of said rod to engage the lower sides of said frames, a segmental. gear-rack pivotally arranged within said box to engage said pinion, a key-lever pivotally attached to the under side of said box, a chain connecting said key with one side of said segmental gear, and a spring secured to the opposite side of said gear and the box, all arranged and combiued as shown and set forth.
In testimony whereof I affix my signature in presence of two witnesses.
J. M. DUPLAN'II.
