MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filed March 28, 1916. Serial N 0. 87,337.

To all whom it may concern:

Be it known that 1, ROBERT L. WEED, a citizen of the United States, residing at Stamford, in the county of Fairfield, State of Connecticut, 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.

The present invention is directed to im- I rovements in music leaf turners, and has for its object to provide a device so constructed that the same can be conveniently attached to the conventional form of upright piano, and when in place thereon can be actuated to turn a. music leaf without the necessity of the player removing the fingers from the keys.

A further object of the invention is to provide a music leaf turner which consists of a minimum number of parts, and one which can be conveniently actuated upon pressing a treadle to actuate the leaf turnmg arm.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure l is a fragmentary rear elevation of a piano, showing the device in place thereon.

Fig. 2 is a side elevation of the same.

Fig. 3 is a top plan view of the same.

Fig. 4 is a sectional view on line 44 of Fig. 3.

Fig. 5 is a similar view on line 55 of Fig.

Fig. 6 is a fragmenta front elevation of a piano, showing the device in place thereon.

Referring to the drawing 1 indicates the back of a piano, and 2 a plate which is adapted to be secured to the back, said plate having its upper edge terminating in a triangular shaped plate 3, which is disposed at right angles to the plate 2 and overhangs the top of the piano.

A socket 4 is formed in the forward end of the plate 3 for receiving the inner end of the arm 5, said arm being retained in the socket by the set screw 6. The outer end of the arm 5 is curved, as at 7 and terminates in a spindle 8 on which is rotatably mounted a sleeve 9 and to which is fixed the inner end of the rod 10 which supports the leaf clamp 11. 1

Mounted on the upper surface of the plate 3 is a sleeve 12 in which is rotatably m0unted a cylinder 18, said cylinder having formed therein a transverse bore 14 in which is engaged the arm 15, said arm having its forward end curved, as at 16 and has its lower end terminating in a spindle 17 on which is rotatably mounted a tube 18, said tube having diametrically disposed slots 19 formed therein for engaging the rod 10, the purpose of which will appear later.

The rear end of the arm projects slightly beyond the rear surface of the back 1 of the piano and has connected thereto one end of a coil spring 20, the other end of which is fixed to the back 1 in any suitable manner.

Pivotally connected to the plate 2 is a bar 21, said bar having its free end provided with a notch 22 which is adapted to be engaged by the rear end of the arm 15 when theclamp 11 is engaged with a music leaf, whereby when the arm 15 is released the spring 20 will swing the arm 15 so as to turn the leaf.

To actuate the bar 21 to release the arm 15, a cord 28 has one end fixed to said bar and is trained around the pulleys 24: which are secured to the case of the piano and has its other end connected to the treadle 25. Thus it will be seen that when it is desired to release the arm, it is only necessary for the player to press downwardly on the treadle, which action swings the bar 21 downwardly so as to release the arm 15.

A leaf spring 26 is fixed to the plate 2 and has its free ends engaged with the bar 21, and serves to yieldably support said arm and return it to its normal position after being actuated upon actuation of the treadle 25.

Fixed to the rear edge of the plate 3, and spaced therefromto provide a guide slot 27 for the arm 15 is a bar 28.

lVhat is claimed is 1. In a music leaf turner, a plate adapted to be connected to the back of the piano, said plate having a triangular plate supported by its upper end, an arm adjustably connected to the triangular plate, a spindle carried by the arm, a leaf carrying rod rotatably supported by the spindle, a leaf clamp carried by the rod, a turning arm overhanging the piano, an arm having its rear end detachably connected to the triangular plate and having its forward end provided with a spindle, a sleeve rotatably supported by the spindle, a leaf carrying rod carried by the sleeve, a leaf engaging clamp carried by the rod, a sleeve carried by the triangular plate, a cylinder rotatably engaged in the sleeve, a turning arm en- Copies of this patent may be obtained for five gaged with the cylinder and having its forward end provided with a tube, means for slidably and rotatably connecting the tube to the rod, a spring connecting the rear end of the leaf turning arm and the right hand side of the piano, a bar pivotally connected to the first named plate and having a notch carried thereby for engaging the rear end of the turning arm to hold the same inits operative position, and means for swinging said bar to disengage the leaf turning arm, whereby the tube will swing the rod to turn a leaf.

In testimony whereof, I aflix my signa ture, in the presence of two witnesses.
