MUSIO-LEAF TURNER.

SPECIFICATION forming part Of Letters Patent NO. 582,586, dated May 11, 1897.

Application filed January 4, 1897. Serial No. 617,912. (No model.)

To aZZ whom, it may concern:

Be it known that we, I'IIRAM HAMMOND and ROBERT HAMMOND, of Lake George, in the county of \Varren and State of New York, have invented a new and, Improved Music- Leaf Turner, of which the following is a full, clear, and exact description.

The object of the invention is to construct a device especially adapted for the turning of the leaves of music, which device will be of simple, durable, and economic construction and will be entirely independent of the instrument in connection with which it is used.

A further object of the invention is to pro vide a means whereby all of the leaves, after they have been turned, may be simultaneously restored to their original position, and whereby, further, any one leaf may be expeditiously and conveniently turned, the turn.- ing being effected without interfering to any material extent with the rendition of the music by the performer.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improved device. Fig. 2 is a horizontal section taken above the frame of the device and through one of the drums carrying the leafturning arm. Fig. 8 is a vertical section through the upper portion of the frame, showin g the arrangement of the catches; and Fig. 4 is a vertical section through the drums, to which the music-carrying arms are attached.

The frame A of the device is preferably of rectangular shape, although it may be given other contour. Between the top and bottom rails or members of the frame a horizontal bar 10 is located, and upon said bar, within a recess made in its front central portion, a clamp 11 is located, and a second clamp 12 is similarly placed at the top of the frame.

Between the horizontal cross-bar 10 and the bottom of the frame a movable table 13 is located within said frame, the said table being preferably provided at its ends with tongues 14, which extend into vertical slots or open ings 15 made in the sides of the frame, as shown particularly in Fig. 1. The table 13 is held in position to support a short or a long piece of music or a book by means of springarms 16, which are attached to its ends, one end of each arm being arranged to enter any one of a number of openings or apertures 1.7 made in the side members of the frame, as is also shown in Fig. 1. Ears 18 are secured in the bottom portion of the frame A, and in each car a key 19 is pivoted, the said keys being preferably placed diagonally of the frame, and the rear ends of the keys are free, as are likewise their forward ends.

A shaft 20 or a stud is secured, preferably at its lower end, in the cross-bar 10, and the said shaft or stud extends upward through and beyond the top of the frame A, and at the left-hand side of the frame a rod 21 is socured upon its upper surface, extending beyond its left-hand side.

The right-hand side bar of the frameis carried above the top of the frame, and a back plate or board 22 is secured to an extension of the right-hand side bar of the frame and to the top of the frame. A series of springcatches 23 is secured to this back board, and these catches are arranged one below the plane of the other and likewise one at the left-hand side of the other. In fact, the spring-catches 23 are stepped, and each spring-catch 23 is provided with a head 2%, the heads having a downward and forward inclination, and a shoulder is formed by the back of the head at the forward end of the body of the springcatch to which the head is secured, as shown in Figs. 1 and 3.

Each spring-catch is connected by a rod 25, made of wire or other material, or a chain or its equivalent, with the rear end of one of the keys 19, so that when the forward end of a key is pressed upward the spring-catch with which it is connected will be drawn downward at its free end or the end at which the head is located.

011 the upper portion of the shaft or stud 20 a series of hollow drums 26 is located. These drums are placed one above the other and are spaced a predetermined distance apart, and each drum has independent move-- ment. Each drum contains a spring 27, and these springs are secured to the shaft or stud 20 at one of their ends and are attached at their opposite ends to the interior portion of the drum in which they are contained, as illustrated in Fig. 4:.

Each drum is provided with an arm 28. These arms are graduated in length, the uppermost arm being the longest and the lowermost arm being the shortest, and the uppermost arm is adapted to engage the uppermost spring-catch 23 and the lowermost arm the lowermost catch, as shown in Fig. 1. These arms are normally forced over the heads of the catches and are held in engagement therewith by contacting with the vertical or shouldered portion of the head, and the arms below the uppermost arm are bent outward and forward to a predetermined extent, the outward or forward bend being increased in each of the lowermost arms. Therefore in the lowest arm 28 the outward bend is much more decided than in the arm next to the top, and each arm 28 carries at its free end, which is downwardly projected, a clamp 29, preferably spring'controlled, but which may be of any desired construction, and these clamps, or clips, as they may be called, are adapted one for engagement with the upper edge of each leaf of music or each leaf of a book 13 that is supported on the table 13 of the device, the back of the book or sheet of music being held between the clips or clamps 11 and 12, attached to the frame.

A band 30, of rubber or a like material, is attached to the right-hand side of the frame at the front, and this rubber band or elastic is adapted to be passed over the last sheet of the music or over the back of the book or the leaf of the book next to the back, so that when the leaves at the front are turned the back of the book or the last leaf in a piece of music will not be moved from its position on the frame.

A yoke 32 is pivoted upon the upper portion of the shaft or stud 20 and is preferably pivoted also upon the said shaft or stud below the lowermost drum 26. This yoke is provided with an an gle-arm 33, which is adapted to extend outward beyond the side of the frame, as shown by positive and dotted lines in Fig. 1.

In the operation of the device, the musicleaf turner having been placed in position 011 the instrument and the leaves having been attached to the clamps or clips 29, when a leaf is to be turned it is simply necessary to carry the hand upward and strike the outer end of one of the keys 1t), whereupon the inner end of that key will be depressed, and the catch 23, connected with the key, will be drawn downward, releasing the m usic-carryin g arm 28, held by the said catch, and the spring 27 in the drum connected with that arm will immediately act to throw that arm from the right to the left hand side of the frame, carrying the sheet of music in the same direction.

Prior to turning any of the sheets of music the an gle-arm 33 is taken over to the left-hand side of the frame, and this angle-arm is primarily adapted to carry the arms attached to the sheets of music to the right-hand side of the machine and to an engagement with their respective catches. The device is exceedingly simple, it is durable and economic, and may be used in connection with a music-stand or a music-rack on a piano or other instrument.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A music-leaf turner having a frame provided with two horizontal bars, one located at the top of the frame and one located intermediately on the frame, each horizontal bar having a notch in its front edge, a clasp scoured within each notch and adapted to hold the inner portions of the leaves of music, a table located below the intermediate horizontal bar and having reduced ends slidable in vertical slots in the side of the frame,the table being adapted to engage the lower edges of the music-leaves, a spring-arm carried at each end of the table,the arms proj ecting upwardly from the table and bearing against the frame to hold the table at various positions, and means on the frame for turning the leaves, substantially as described.

2. A music-leaf turner having a frame with side portions and two horizontal bars, the bars being located one at the upper end of the frame and one intermediately on the frame, the forward edge of each horizontal bar beiu g notched and the lower part of each side portion of the frame having slots, a table the ends of which are reduced to lit the ends of the slots whereby the table is slidable vertically on the frame, a spring-arm secured to each reduced end of the table and projecting upwardly therefrom to engage the sides of the frame, the sides having a series of verticallyalined perforations receiving the spring-arms, and leaf-turning devices carried by the frame, substantially as described.
