OTTO B. WILLI, 0F YOUNGSTOWN, OHIO.

MUSIC-LEAF HOLDER AND CLAMP.

To all whom it may concern:

Be it known that I, O'r'ro B. WVILLI, citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Music-Leaf Holders and Clamps, of which the following is a specification.

This invention relates to music holders and clamps especially adapted to be used in conjunction with keyboard instruments and upon music stands, and has for its object to provide holding mechanism which may be easily and readily adjusted to be ac commodated to sheets or books of difierent sizes and which may be quickly and easily manipulated or operated to effect the turning of the leaves.

The present invention is an improvement in the structure shown in my earlier application forpatent for music leaf turner, filed March 11, 1910, Serial No. 548,691.

The parts of the present invention are so arranged that they may be applied to the panel and music shelf of an instrument case or to a music stand without altering or mutilating the same to any considerable extent, and provision is made for concealing the major portions of the parts behind the panel or stand when the holder is not in use.

In the accompanying drawings:Figure 1 is a perspective view showing the holder and clamp applied to the panel and shelf of the case of a piano; Fig. 2 is a transverse sectional View through the panel showing the holder and clamp applied; Fig. 3 is a horizontal section through the panel showing the holder and clamp applied; Fig. 4 is a horizontal sectional view of a clamp used in the device; and Figs. 5, 6, and 7, detail views of modified parts of the device.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

As indicated in the drawings, 1 represents the hinged panel of the case of the instrument which is provided at its lower edge with the usual music shelf 2.

3 indicates that portion of the case which Specification of Letters Patent.

is located just above the key bank 4 of the instrument.

A cylinder or body 5 is fixed to the rear side of the panel 1 and contains the mechanism for swinging the arms, hereinafter to be described, and this mechanism is operated by levers 6 which project through the portion 3 of the case of the instrument and are located just above the key bank 1'. The mechanism located within the cylinder 5 for swinging the arms may be the same as that shown and described in connection with the mechanism illustrated in my earlier application hereinbefore referred to, and as this mechanism forms no part of the present invention, description of the same is unnecessary in the present instance. Su'lfice it to say that the arms 7 are pivot-ally mounted at their inner ends within the cylinder or body 5 and are adapted to swing in planes at right angles to the long dimension of the said cylinder or body 5. The arms 7 carry at their outer ends leaf holders 8 which are of especial design and construction, as will now be described. These holders consist each of two opposed thin strips of metal which are provided at their edges with diverging flanges 9. The side portions of the holders 8 may be formed by bending a single strip back upon itself or may be composed of two independent strips secured at their lower ends to the arms 7. When the levers 6 are depressed the arms 7 and their attachments are swung successively by the mechanism hereinbefore referred to located in the cylinder or body 5 and which is not shown. The upper ends of the holders 8 are enlarged forming heads 10.

The panel 1 is provided at its lower edge with a. vertically disposed slot 11, best seen in Fig. 1 of the drawings, which is provided at its upper end with an enlargement 12. At its lower end the slot 11 enters the rear end of an arcuate slot 13 provided in the shelf 2. These slots 11 and 13 are located at one side of the cylinder or body 5, and at the opposite side of the said cylinder or body the shelf 2 is provided with an arcuate slot 14 which is located the same distance from the said cylinder or body as the slot 13.

A rod 16 is slidably mounted in the shelf 2 and is provided at its outer end with a knob 17 which normally bears against the outer edge of the shelf 2. At its inner end the rod 16 is provided with an angular extremity 18 which extends transversely across and behind the innermost arm 7 The body portions of the arms 7 are at the same elevation and are arranged one behind the other. Therefore it will be seen that when the rod 16 is moved forward by a performer pulling the knob 1'? the extremity 18 of the said rod 16 will engage the innermost arm '7 and move the free end thereof together with all of the other arms 7 out through the slot 11 beyond the forward surface of the panel 1. Thus the holders 8 are brought to accessible positions and the performer may place the leaves of a book or sheet music between the side strips of each holder.

Clamping mechanism is provided for holding that portion of the music which is not to be used in close relation to the panel. As illustrated in Figs. 1, 2, 3 and 4: this clamping mechanism consists of

sleeves

1 and 20 which are inserted in the lower edge of the panel 1 and the outer edge of the shelf 2 respectively. A tube 21 is slidably mounted in the sleeve 19 and carries at its outer end a resilient finger 22. The tube 21 provided at its inner end with an enlarged head 23 which is provided at its rear side with a diametrically disposed recess 24. A coil spring 25 is interposed between the inner end of the sleeve 19 and the head 23 and is under tension with a tendency to hold the finger 22 toward the outer surface of the panel 1. A rod 26 is slidably mounted in the tube 21 and is provided at its outer end with a knob 27 which normally bears against the outer end of the sleeve 20 and limits the inward movement of the said rod 26 and the tube 21. At its inner end the rod 26 is provided with a cross head 28 which at times is adapted to seat in the slot 24: provided in the head 23, whereby the rod 26 may be used as means for turning or partially rotating the tube 21 and its attachments. The shelf 2 is slotted as at 29 to receive the outer portion of the rod 26 and along which the lower end of the finger 22 and the outer end of the tube 21 may pass. From the outer end of the slot 29 the shelf 2 is slotted as at 30, the slot 30 extending generally at a right angle to the long dimension of the slot 29, and is adapted to receive the finger 2 when the same is pulled toward the outer edge of the shelf 2 and is swung in a downward direction. The slot 30 is provided at that end remote from the slot 29 with a ledge 31 upon which the free end of the finger 22 may rest and which limits the downward swinging movement of the said free edge of the finger with relation to the shelf 2. hen the finger 22 is received within the slot 30 the tube 21 and its attachments are held in outward positions against the tension of the spring 25. The clamping device as above described is duplicated, one device being located at each side of the cylinder or body 5.

The clamping devices, as has been hereinbefore stated, are designed to hold the pertions of the music which are not to be used in close proximity to the outer face of the panel, and in positioning the music upon the panel it is opened and the portions not to be used are placed between the panel and the fingers 22 and the springs 25 hold the said fingers against the said portions of the score, while the leaves which are to be used are positioned in the holders 8, as hereinbefore described. Thus the leaves of music may be turned at will, and when the holders 8 leave the slot 13 in the shelf 2 they swing across into the slot 141- in the said shelf. There they may remain until they are swung back by the performer.

In the form of clamp as illustrated in Figs. 5 and 6, the coil spring 25 is dispensed with and two springs are employed. One of these springs 32 is attached at one end to the back of the panel 1 and at its other end is connected with one end of the rod 26 and is under tension with a tendency to hold the knob 27 toward the edge of the shelf 2. The other spring 33 is attached at one end to the back of the panel 1 and at its other end bears against the forward face of the head 23 and is under tension with a tendency to hold the tube 21 within the panel 1 and the finger 22 carried thereby toward the outer face of the said panel. This form of clamp is manipulated in the same manner as that described in connection with the form shown in Figs. 1, 2 and 3 of the drawings.

In the form of clamp as illustrated in Fig. 7, but a single spring is employed, this spring being indicated at S t and has one of its ends attached to the shelf 2 and its other end bearing against the head 23 of the tube 21. In this instance the tube 21 is much shorter than the tubes shown and described in connection with the clamping devices illustrated in Figs. 1 to 6, inclusive, and therefore the parts do not project to any considerable extent behind the panel 1.

Having thus described the invention, what is claimed as new is:

1. In combination with a leaf turning means mounted upon a support, a clamp comprising a spring pressed tube slidably mounted upon the support, a finger carried by the tube, said support having a slot adapted to receive said finger, and a rod slidably mounted in the tube and carrying means for engaging the same to slide and turn the same.
