IVlUSlC OR BOOK L-AF TURNER.

SPECIFICATION forming part o' Letters atent No. 646,405, dated April 3, 1900.

Application tiled April 28,1899. Serial No. 714,895. (No model.)

To all whom it' may concern:

Be it known that we,WILLIAM S. ALTER and ELLIS W. ANCHORS, citizens of the United States of America, residing at Tarentum, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Music or Book Leaf Turners; and we do hereby declare the following to be a full, clear, and eXact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

Our invention relates to certain new and useful improvements in music or book leaf turners, and has for its object to construct such a device as will be automatic in its operation, whereby a performer may turn one page after another and obviate the necessity of ceasing the performance for turning the pages.

Our invention finally consists in the novel combination, construction, and arrangement of parts, as will be hereinafter more specically described, and particularly pointed out in the claims.

ln the accompanying drawings, Figure 1 is a front elevation of our improved music-leaf turner, showing one of the leaf retaining frames turned and the other retained by catches, the said view showing the general construction and arrangement of our improved device. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged side elevation of a portion of the central hinge-bar, showing the manner in which each individual frame is hinged and fitted with springs for turning or revolving the same. Fig. 4 is an enlarged sectional elevation of the base, taken at the releasing-keys.

To construct a music-leaf-turning device in accordance with our invention, we provide a base-piece 1, having an inclined under surface to conform with the angle of the shelf of a piano or organ. This base is connected to a'frame 2 in the form of an oblong and is divided into two sections, the one joined to the other by suitable hinges 3, which admit of the said sections being folded together to occupy a small space. Centrally arranged in suitable bearings 8 of this frame 1 2 is a supportingshaft 7, to which each individual leaf-holder is loosely hinged or connected by means of angular projecting portions 26, arranged at the top and bottom of the said holders. Each of these holders 6 6'6" consists of a thin metallic frame provided at the base with a groove 9, in which the music-leaf is held, and at one side and top with adjustable grooved pieces 11, pivoted or loosely connected by short links 12 in a manner that the said pieces 11 may be moved in the position shown at the right of Fig. 1 or folded close to the frame, as shown at the opposite side of said frame. Connecting the base of each of the holders 6 6' 6 is one end of aspring 10, coiled spirally about the supporting-shaft 7 and the other ends of the said springs attached to the bar in a manner that will place a tension upon the springs to throw the holders from right to left. These holders 6 6' 6l are held the one over the other at the right of the frame 1 2 by verticallyarranged bars 13 engaging with small depending pieces 14., attached to the base of each holder. These bars or locks are connected to horizontally-arranged levers 17, pivoted within the base 1, and connected to the said bars by means of pins 18, operating in slots 13. Attached to the outwardlyprojecting ends of the levers 15 are fingerkeys 16, which when pressed downward will carry the bars 13 in the same direction, thereby releasing their hold upon the catches 14. The lever 15 and bar 13 are brought back to their normal position by a spring 19, arranged beneath.

In operation the sheets of music are arranged in the holders 6 6 6 by entering their edges into the grooves 9 at the base and into the grooves of each of the adjustable'pieces 11 and at the top and side and all the holders turned to the right and held secure in that position by the locks 13.

To turn the music, it is only necessary to press the proper releasing-key 16, and the spring 10, being under tension, will revolve the first holder 6 from right to left.

By the use of the adjustable side and top pieces 12 music-sheets of any ordinary size may be held in the holders, as is obvious.

Various slight modifications may be made in the construction and details of our invention without departing` from the spirit of the sanie.

Having thus described our invention, We clairnl. In a music-leaf turner, the combination of a base, a frame connected thereto and eonsisting of two sections hinged togethe1,ajour naled supporting-shaft, a series 0i' springe@- tuated leaf-turners consisting' of an oblong' iraxne connected to said shaft, adjusting means for the music-leaves consisting of a grooved bar pivotally Connected to a pair of links which are pivotally connected to the turners, a series of spring-actuated vertical bars for retaining` the said turners in the locked position, and means for operating` the said bars, substantially as described.

2. In a music-leaf turner, the combination with a base having an upwardly-extending frame suitably connected thereto, of a supporting-shaft journaled within the frame, :L series of coiled tension-springs mounted on said shaft, a leaf-turner connected to each of said springs,an adjusting means for the leaves consisting of a grooved bar pivotally connected to a pair 01:' links which are pivotally oonneoted to eaeh of the leaf-tnrners, a series of spring-actuated Vertical bars for retaining the said turners in aloeked position, and a series of levers pivotally secured in the said base for operating the said bars, substantially as described.

In testimony whereof we have hereunto at'- ixed our signatures in the presence of two subscribing Witnesses.
