FRANK M. JONES, OF DINUBA, CALIFORNIA. 1
MUSIC-LEAF TURNER.
To do whom it may concern:
-Be it known that I, FRANK; M. JoNns, a
citizen of the United. States, residing at Dinuba, in the county of Tulare and State of California, have invented new and useful Improvements in Music-Leaf Turners, of
which thefollowing is a specification.
vThe invention relates to music leaf turners, and more particularly to the class of automatic music leaf turners.
- The primary object of the invention is theprovision'ofa music leaf turner wherein the music turning arms are acted. upon through the medium of springs which are SUCCBSSlVBlY released for the turning of the sheets of music in their order, thereby avoiding the handling of the said sheets for this purpose. Another object of the invention vis the provision of a turner of this character wherein the tension of the springs can be varied accordingly to the weight of the sheets of the music to assure. the positive turning thereof when the music is in use.
A further object of the inventionis the provision of a music leaf turner of this character wherein the .construction thereof is novel in form for accuracy in the working.
thereof.
"A still further object of the invention is the provision of a music leaf turner of this character which is simple in construction, reliable and eliicient in its operation, strong,
' durable, and inexpensive in manufacture.
With theseand other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.
In the drawings p Figure 1 is a front elevation of the music leaf turner constructed in'accordance with the invention. Fig. 2 is a top plan view thereof. F ig. 3 is an end elevation. Fig. L is a sectional view 5n the line H of Fig. 1. Fig. 5 is a sectional view on the line 55 of Fig. 1. Fig. 6 is a vertical transverse sectionalview of the lower part of the mecha-.
nism.
Similar reference characters indicate corresponding parts throughout the several views in the drawings.
Referring to the drawings in detail, the
musieleaf turner comprises frame A inupper and lower plates 20 and 11 cludi my, which are spaced. par
Specification of Letters Patent, Pat t d 11' 19 Application filed November 6, 1915. Serial no. 60,093.
each ofwhich engages a locking .dog 25 which is held in looking' by a clip or otherwise.
allel relation and united through the medium of 'verticalcolumns or posts 12 at the ends thereof, while journaled in these plates is a plurality ofspaced vertical shafts 13, in the upper ends of which are fined the stems l lof horizontally disposed music leaf turnchain 18 wrapped about the'said sleeve 16,
andth'ese chains are connected to an adgusting bar or-rod 19 which is slidably .mounted in guides 20, one of which is formed with a keeper 21 with which is adapted to engage a latch nib 22 formed on the rod' or bar 19 so as, to lock the same in position for holding the spring under high tension, the 'outer end.v of the rod or bar 19 being formed with a finger knob 23 so that it can be readily and easily adjusted to vary the tension'of the springs-17 for a purpose presently described. The sleeve '16 on the shaft 13 can be supported from slipping downwardly in any suitable manner.
Formed on or fixed to the lower ends of the shafts 13 are ratchet wheels 2a with pawl or position through the medium ofa leaf spring 26 act ing thereon and suitably fixed to the lower plate 11 of the frame. These dogs or pawls 25 are released through the medium of push rods 27 connected thereto and slidable through a front plate 28 mounted on the frame, the outer ends of the rods being formed with finger buttons 29 so that they can be pushed inwardly for releasing the dogs or pawls 25 to free the shafts 18 which are acted upon by the tension of the springs 17 for the turning of themusic leaf turning arms 15 which carry fingers 30, each being adapted to lie against the sheet at the back thereof when at the right hand side of the. music leaf turner so as to work against thefsheet when the arm 15 swings to push the sheet during the turning of the arm, "thereby avoiding the wrinkling of the sheet should the arm be connected thereto It will be apparent that the finger slides over the face of the sheet during the turning thereof on the swinging of the arm. 15.
Fixed to the upper plates 16 and rising this cord 33 is adapted to bridge the music at the line of fold of the sheets thereof so as to hold the saino fastened in position upon the music leaf turner. c
The tension of the springs 17 is varied'so asto assure the positive turning of the sheets of the music when connected thereto irrespective of the weight thereof.
In the use of the music leaf turner the music is hung u on the standard 31 b the cord 33, and the leaves thereof are attached to the turning arms 15, it being understood of course that the shafts 13 are locked ation of the device will be clearly un ings, the construction and manner of opererstood, and therefore a more extended explanation has been omitted.
ldlhat is claimed is A; music leaf turner comprising a support, a vertical shaft journaled in said support, music leaf turning arm operated by said shaft, a sleeve loosely surrounding the shaft, 2. coiled tension spring encircling said sleeve and having one end fixed to the shaft, a ratchet disk fixed to the shaft, a ratchet pawl pivoted in the support and engaging the ratchet disk, a spring acting upon the pawl to hold the same .in normal locking engagement with the disk, a push rod connected with the ratchet pawl for moving the same to release the disk, a rod horizontally. disposed in the support and slidable therein, a chain connected with the last named rod and to the other end of the spring, a keeper on the support and a nib formed on the last named rod for locking engagement with the keeper to hold said rod in adiusted position and thereby increase or decrease the tension of the sprin In testimony whereof I my signature in presence of two witnesses.
