SIGURD W. JOHNSON AND JESSE H. ABER-LE, OF MINNEAPOLIS, MINNESOTA.
MUSIC-LEAF TURNER.
Specification of Letters Patent.
Patented Dec. 14, 1915.
Application filed December 22, 1913. Serial No. 808,173.
To all whom it may concern:
Be it known that we, Sistine XV. Jonnson and J nssn ll. Annnnn, citizens of the United States, residing at l\liuneapolis, in the county of Hennepin and State of l\1[innesota, have invented certain new and useful 1mprovements in Music-Leaf Turners, of which the following is a. specification.
Our invention relates to improvements in music leaf turner-s, its object bei to provide a simple and positive construction of mecl'ianism which will support the sheets of music, and by which any one of the sheets may be turned, forwardly and haclnvardly.
To this end the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.
In the accompanying drawings forming part of this specification, Figure 1 is a front elevation of our improved mechanism shown supporting a plurality of sheets of music; Fig. 2 is a top view of the mechanism; Fig. 8 is an end view of the same; Fig. l is a front elevation of the mechanism with the music removed; Fig. 5 is a rear elevation with the back plate removed; Fig. 6 is a top view with the top plate removed; Fig. 7 is a front view of the mechanism with the front plate removed; Fig. 8 is an end view with the end plate removed Fig. 9 is a detail of a clip forming part of the mechanism, and Fig. 1.0 is a perspective view of a portion of the operating mechanism with the inclosing casing removed.
leferring to the drawings A represents a casing forming a support for the different features of our invention. Centrally journaled in the rear side of the casing is a post 2 upon which are rotatably mounted a plu rality of pinions 3. Each pinion supports an outwardly extending arm l which arm at its free end supports a clip 5. The clip 5, as shown specifically in Fig. 8, is formed with fixed and movable aws 6 and 'Tto allow a sheet 8 of music to be supported between said jaws. As many sheets of music may be turned with our apparatus as there are pinions and supported arms.
Having slidable support 9 in the rear of the casing is a plurality of racks 10 separately intermeshing with the pinions. lVe preferably, as shown in the drawings, arrange half of said racks to extend from half of the pinions to one end of the casing and the other half of the racks to extend to the opposite end of the casing. Having pivotal support in the outer end of each rack bar is a forwardly extending arm 11 supporting at its free end a segmental pinion 12 rotatable upon a post 18. The segmental pinion 12 intermeshes with teeth upon the adjacent side of a key plunger 14, which plunger 14 extends through the front of the casing and supports a finger key 15. There are thus a number of keys corresponding to the numher of sheet supporting arms. The pressing inward of any one of the keys upon the left hand side will thus slide inwardly the corresponding rack bar and through the supported arm turn the supported sheet of music from the right to the left. The segmental pinions in the opposite ends of the casing being arranged in connection with the lower plungers, will, as will be evident, when the lower keys upon the right hand of the casing are pushed inward, pull the corre-.
sponding rack bars outward instead of pushing them inward. Thus the depressing of any one of the upper rows of keys upon the left or lower keys on the right side will, as will be evident, swing the supported sheet of music from the right to the left hand side of the folder.
Slidably supported in the casing underneath the left hand row of keys and above the right hand row is a row of keys 16. The bar 17 of the keys 16 is slidable in the casing and each bar 17 at its inner end is connected with the key bar 14 by a link 18 having central fulcrum support 19. Thus when one of the keys 14 is shoved in it will shove outwardly the corresponding keys 16. It will be evident that for any of the keys 14 that will stand pressed in, its supported sheet of music and those sheets to the left of it will be swung to the left hand side of the folder. Where it is desired to turn any of the sheets that stand upon the left hand side of the folder back to the right hand side of the folder the shoving inward of any one of the kevs 16 will oppositely actuate the connected key 14L and the mechanism leading therefrom to the sheet support to turn the suppo ted sheet and those sheets to the right of it f om the left to the right hand side of the holder.
As will be clear from Fig. 6, each vertical pair of push rods 14 and bar 17 is connected at its inner ends to links .18 having fulcrum support 19 (see Fig. Bl. The pintle rods 14 have teeth upon their inner sides, as shown in Fig. 6, which intermesh with adjacently supported Jinions 12 which pinions in turn are independently connected by links with the rack bars 9 which intermesh with the pinions 8. Thus every time you shove in one of the bars 1% you will, as will be evident in Fig. 6, turn the intermeshing pinion 12 and through the arm 11 slide the rack bar to turn the leaf support ing pinion 3 in one direction. This sliding in of one of the bars a will, of course, through the medium of the connecting link 19 push outwardly the connected lower bar 17. On the other hand, as will be evident by retel-ring to Figs. 6 and 8, you will, by pushing in the bar 17, push outward the connected bar let and oppositely rotate the intermeshing pinion 12 and move the rack bar 9 in the opposite direction to what it is moved when you push in the bar 14.
We claim as our invention:
1. A leaf turner of the class described consisting of a plurality of leaf supporting arms supported by independent rotatable pinions, a common central shaft for said pinions, means carried by the outer ends of said arms in position to engage with the bottoms of the leaves of a supported book, a plurality of slidable bars operatively engaging with said pinions, a pair of push rods for each bar and operative connections between said push rods and bars whereby the sliding of the one push rod will slide the bar in one direction and move the connected push bar outwardly in position to be operated to turn the leaf supporting arms.
2. A leaf turner of the class described consisting of a plurality of leaf carrying arms supported by independent rotatable pinions, a common central support for said pinions, upwardly extending clips carried by the outer ends of said arms to engage with the bottoms of supported leaves, a plurality of slidable bars independently engaging with said pinions, a set of push rods operatively connected with said bars and operative when slid inwardly to slide the bars outwardly, and a second set of push rods connected with said first set of push rods and operative when pushed inwardly to restore the first set to normal position and slide the bars outwardly to turn the leaf supporting arms.
In testimony whereof we afliX our signatures in presence of two witnesses.
