LEAF-TURNER.
Specification of Letters Patent.
Patented Oct. 16, 1906.
Application filed February 24, 1906. Serial No. 302,712.
To all whom it may concern.-
Be it known that I, OSCAR F. HALVERSON, a resident of Janesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Im rovements in Leaf-Turners; and I do hereby declare the following to be a full, 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.
My invention relates to improvements in leaf-turners, the object of the invention being to provide improved mechanism for moving a magnet to turn the leaves; and the invention consists in certain novel features of construction and combinations and arran ements of parts as will be more fully hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view in elevation, illustrating my imrovements. Fig. 2 is a view in section. ig. 3 is a sectional view illustrating the attachment of the clamp 9. Fig. 4 is a detail view showing the attachment of the magnet to the rod 14. Fig. 5 is an enlarged rear view, partly broken away, showing the musicsupport and devices for o erating the arm or rod 14. Fig. 6 is a detafl view showing the shaft 13, spool 20, and rod 14.
1 represents my improved music-holder, which is preferably mounted on a telescoping rod 2, supported by a folding tripod 3.
The music holder or rack 1 may be made in a great many ways; but I prefer to employ one of the folding type which permits it to be folded into small space for transportation.
To the back of the center bar of the music rack or holder 1 a plate 4 is clamped by bands 5, pivotally secured to the plate at one end, extending over the face of the center bar and securely clamped by screws 6 and thumb-nuts 7, as clearly shown, and an upwardly-projecting rod 8 is secured adjustably to the center bar by clamps 9. This bar has a cord 10, secured in openings in its upper end and is adapted to'be passed down the fold of the music and secured to the plate 4 to hold the music in proper position on the rack.
Below the music-supporting bar 11 of the rack the plate 4 is made with an car 12 stamped therefrom and having an opening alining with a similar opening in an ear 12* at the lower end of plate 4 to receive a short shaft 13, on which a spool 20 is secured, and a rod 14, located at right angles to shaft 13, is
secured thereto or made integral therewith. This rod 14 is flattened or made angular to enter an angular opening in a bracket 1.5, adjustably secured on the rod by a thumbscrew 16, and this bracket 15 sup orts a magnet 17 to attract metal disks or p ates 18 on the music leaves or sheets and turn the leaves, as will be hereinafter explained.
An eyebolt 19 is passed through spool 20 and sh aft 13, rigidly securing them together, and a cord 21 is secured to the bolt 19, passed around. spool 20, thence through the opening in plate 4 over a pulley 22, and down to a treadle 23. The treadle 23 is made approximately A shape, with its longitudinal bars pivotally secured together and connected by a cross-bar pivotally secured at one end and removably secured at its other end to permit the treadle to be folded for shipment, and the free ends of the longitudinal bars are bent and sharpened, forming teeth 25 to engage in the carpet and prevent movement of the treadle out of positon beneath the operator s foot. Pulley 22 is supported at the end of a wire or other spring 26, secured to plate 4 by a thumb-nut 28, and has one or more coils between its ends to give to the spring the necessary tension. The free end of the spring 26 is connected by a cord 29 with the bolt 19 in spool 20, so that when the spool is turned by cord 21 to turn a leaf the cord 29 will be wound on the spool and draw the spring 26 downward, and when pressure is released from the treadle the sprin will draw the cord 29 outward, turn s 00 20, and return the parts to their norma positions.
To the right -hand lower corner of the music-holder or rack 1 a plate 30 is clamped, as shown, to rest back of the corner of the leaves and receive the shock of the returning magnet and hold the leaves in position to be engaged by the magnet.
I do not confine myself to any particular manner of fastening the metal plates or disks 18 to the leaves, as this may be done in a great many ways, and the thin plates or disks used for the purpose will not disfigure the music nor detract in anyway therefrom.
It will be observed that shaft 13 and spool 20 are located sli htly to the left of the center of the music radk or holder, which compels the magnet to move in an arc of a circle different from the metal disks or plates 18, and hence the magnet as it nears the left of the rack after it has thrown or turned the leaf 11 will draw away from the disk or plate and be ready to return to its former position without the leaf it has turned. I
The operation of my improvements is as follows: The normal position of the ma is on the right-hand side of the rack or ho der gggmst the metal disk on the music-leaf.
en pressure isapplied on treadle 23, the I cord 21 will be drawn down to turn spool 20, and thus swing the rod 14 and magnet 17, and the engagement of the magnetwith the metal disk 18 will cause the leaf to follow the magnet until the latter reaches a point near its extreme throw, when the difference in the arcs through which the magnet and leaf move will cause the magnet to slide off the I metal disk and release itself therefrom. This turning movement of spool 20 winds cord 29 thereon to pull down spring 26, and when pressure on the treadle is released spring 26 will pull cord 29 to turn spool 20 in the reverse direction and return rod 14 and magnet 17to their former and normal positions to engage the metal disk on the next leaf to be turned. The operator is thereby enabled to turn the leaves by pressure of his foot on treadle 23, and his hands are free for use with the musical instrument he is playing.
A great many made in the general form and arrangement of the parts described without departing from my invention, and hence I- do not reslight changes mightbe strict myself to theprecise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the s irit and scope of my invention.
Having fully described my invention, What Ilclaim as new, and desire to secure by Letters Patent, is
1. In a leaf-turner, the combination with a leaf-support, of a spool, a rod secured to the spool, a magnet on the rod, a spring, a pulley carried by said spring, a treadle, a cord securedto the spool, wound thereon, passed isecured to the treadle, and the spring and spool. k 2'. In a leaf-turner, the combination with a leaf-support and metal pieces to be attached ;to the'leaves to be turned, of a spool located to the left of the center'of said support, a rod secured to the spool, a magnet secured to the rod a cord connecting fnectin'g the spring and spool, a treadle, and a passed over the pulley. i In testimony whereof I have signed this specification in the presence of two subscribing witnesses. I OSCAR F. HALVERElON.
