To all w/Lom t may concern.:
Be it known that I, CHARLES FArsT, a citizen of the United States, residing at Spring Valley, in the county of Rockland, State of New York, have invented certain new and useful Improvements in Music- 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.
This invention relates to music leaf turners.
The object of the invention is to provide a music leaf turner which will be exceedingly simple in construction, which can be operated with little effort, which will be eilicient in action, and which can be manufactured at an exceedingly low cost.
Vith the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.
In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which- Figure 1 is a view in eleva-tion of a music leaf turner constructed in accordance with the invention;
Fig. 2, a top view with one of the turning arms partially actuated to full leaf turning position;
Fig. 3, a section on the line 3 3 of Fig. 1;
Fig. 4, a section on the line 4 4 of Fig. 1, and
Fig. 5, a perspective view of one of the leaf turning arms detached.
Referring to the drawing the improved music leaf turner is shown as comprising a A against which the sheet of music is adapted to be secured. Mounted upon the face of the body A is a longitudinal strip 10 one end of which has mounted therein a staple or eye 11 in which is engaged the hook terminal 13 of a clamping bar 14. The end of the clamping bar 14 remote from the terminal 13 is bent laterally to form a handle 15. The strip 10 projects beyond the upper edge of the body A and has removably engaged thereon a sleeve 16 which holds the bar 14 in clamping position with respect to a sheet of music disposed between the bar and the strip. By removing the sleeve 16 and lifting the bar 14 it will be obvious that a desired sheet of music can be readily applied to and removed from the body A. Mounted on the body A transversely thereof at the end of the strip 10 carrying the eye 11 is a ledge 17 which has mounted thereon an arm throwing cam 18, the purpose of which will presently appear. Mounted on the legs 17 are spaced brackets 19 which support a rod 20 having slidably mounted thereon av plurality of sleeves 21. Secured to each sleeve 21 is a leaf turning arm 22 formed of a single length of wire coiled about the related sleeve 21 adjacent one end of the arm and extending to one side of the sleeve to form a handle 23 which is gripped to slide the sleeves and the arms longitudinally of the rod 20. It will of course be understood that the arms are rigidly secured to respective sleeves and that the latter are rotatable on the rod 20.
In the operation of the device the sheet of music is secured in place by means of the clamping bar 14 in the manner previously referred to and the arms 22 are inserted between the leaves all of which latter are disposed on the right hand side of the body A. When the first page of the music has been played and it is desired to turn to the next page the sleeve 21 and arm 22 to the left in Fig. 1 is manually operated to effect the desired turning of the page. During manual movement of the arm 22 in turning the page said arm will engage the cam 18 and the latter will operate to throw the arm outwardly and impart a sharp turning movement to the leaf. This operation is repeated by moving successive arms to the left until all the leaves have been turned.
What is claimed is A music leaf turner comprising a body means on the body for securing sheets of music thereto, a rod mounted transversely of thebody, a plurality of sleeves slidably and ce Lemeea rotatably mounted on the I'od, a plurality away from the body during sliding;- moveof leaf turning arms having portions thei'ement of the related sleeves on the rod.
