MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 470,151, dated March 1, 1892. Application filed July 28, 1891. Serial No. 400,971. (No model.)

To all whom it may concern:

Be it known that I, HENRY S. BREWINGTON, a citizen of the United States, residing at altimore city, in the State of Maryland, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

This invention relates to an improvement in music-leaf turners; and the object isto provide mechanical means for turning the leaves of a piece of music or for turning a number of leaves of a music-book, which may be operated by a very slight movement of the hand, and will act quickly to turn the leaves.

IVith these ends in view theiuvention consists in the novelfeatures of construction and combinations of parts, which will be described hereinafter, and pointed out in the claims.

The invention is illustrated in the accompanying drawings, in which Figure 1 represents a plan view of the device, showingthe apparatus set with twoleaves ready to be turned and one already turned; Fig. 2, a side view of the same; 3, a section on line 3 3 of Fig. 1, representing one of the leaves in the act of being turned; Fig. 4, a section on line 4. 4. of Fig. 1; Fig. 5, a top view of the rock-shafts which carry the releasing-triggers; Fig. 6, a longitudinal section through one of the outside tubes, showing the triggers; Fig. 7, a side view of said tube, showing the trigger holding the turning-rod Fig. 8, a top View showing the construction at the ends of the tubes; Fig. 9, a section on line 9 9 of Fig. 8, and Fig. 10 a section on line 10 10 of Fig. 8.

The letter A designates the base-board on which the mechanism is mounted. At opposite sides of this board are located a series of parallel tubes B. In the present instance there are three on. each side, and these tubes are supported by standards 0, so that they have position a suitable distance above the board A. Each tube has a slot Ct in its upper side extending from one end a little more than half the length of the tube, and each tube contains a spiral spring D. A red is provided for each pair of tubes, and these rods turn the leaves. Each rod extends from one tube on one side of the board to the corresponding tube on the other side. Thus one rod E extends from the inside tube at one side to the inside tube at the otherside, while the next rod E extends from the middle tube at one side to the middle tube at the opposite side, and the third rod E from the outside tube at one side to the outside tube at the other. In each tube is a slide F of cylindrical form, and the ends 0 of the rods E E are bent to lie in the direction of the tubes and are securely riveted or otherwise fastened to the said slides F. respectively, the said ends 0 of the rods lying in the slots at in the tubes. These rod ends have an upward bend at c to allow the rods to move freely above the tubes. The spiral springs D inside the tubes bear against the slides F and normally keep them, and consequently the rods, at the ends of the tubes. A ring d is secured to each of the said slides and encircles the tube in which the slide works.

At the middle of the board A are three parallel rock-shafts G G G which extend across the board and beneath the tubes B and have bearings in standards I, secured to said board. Each rock-shaft has two projecting catches or triggers e, one engaging in an opening 6' in one of the tubes at one side of the board and the other engaging in a similar opening in the corresponding tube at the opposite side of the board. A spring f is disposed on each rock-shaft to hold its triggers up in the openings in the tubes, and each shaft has at one end an arm 9 with a key or finger-piece on the end thereof. The rockshaft G, whose triggers engage the two inside tubes, projects beyond the other two, and its finger-piece or key II is consequently nearest the operator. The shaft G for the middle tubes and rod projects beyond the other shaft G so that its key II comes next the key of the first-named shaft, whereas the key H of the third shaft G whose triggers engage the outside tubes, comes next the board A.

At the middle of the board is a raised cross-piece I, which forms a rest for the middle part of the book or piece of music, and above this cross-piece is a rod L, which is hinged at one end to lugs h, projecting from one of the inside tubes. This rod is bowed downward at its middle, which makes it bind 011 the book or piece of music resting on the cross-piece I, and enables it to hold securely a single sheet.

The rod is somewhat resiltent, and is held down bya spring-catcl1i,engaging its free end. It can be released by simply pressing back the spring-catch with the finger. The rod may then be thrown up on its hinges to admit of the removal of the matter it has been holding and the introduction of something difierent.

Stands or rests K are provided to support the leaves of the open bookor piece of music, as illustrated in Figs. 2 and 3. A hinged wire frame J is also provided to hold down the leaves and is actuated by springs la.

The operation of the device may be described as follows: The book or piece of music is opened and placed with its middle part on the cross-piece I, and the rod L is brought downupon it and held by the spring-catch i. The leaves rest on the stands K. The rod E,

which is farthest from the left-hand end of the board is now drawn across the book, theslides F, to which its ends 0 are connected, sliding through the tubes and compressing the springs 1 D. The rod is carried past the middle of the book and the rings d, sliding over the outside of the tubes, push back the catches or triggers e of the rock-shaft G nearest the middle of the board and pass said triggers, when the latter immediately spring up again and hold the rings and the rod. A leaf is now turned over thisrod E and held down by the springframe J. The next rod E is now drawn over thebook and held in the same manner as the other rod by the triggers of the rock-shaft G and a second leaf is turned over on this second rod and held by the spring-frame. The remaining rod E is slid forward and held by the triggers of the rock-shaft G and another leaf turned over it and held by the said springframe. It will now .be seen that upon pressing down the key II the triggers of the rockshaft G release the rings d and the springs D return the rod E quickly to the end of the board and turn the leaf which is over said rod in the manner represented in Fig. 3, and that by pressing the keys H H the other two rods E E will operate in like manner to turn the leaves which are over them. In this way eight pages of music may be read, and it will be obvious that as many more rods and tubes may be provided as desired. The leaves af ter being turned take position under the rods which have turned them, and thus are prevented from turning back.

The apparatus is rendered adjustable to books or pieces of music of various dimensions as follows: At the ends of the parallel on the tubes toward the center of the board the rods E E E may be adjusted to a book or piece of music having leaves of less width,

as the blocks will hold the rods so that they will be over the turned leaves and will hold the same down. The spring-frame J is pivoted to blocks T, which slide on the inside tubes, and thus this frame may be adjusted to hold down leaves of different widths. The

tube-standards p at the middle of the board project up between the tubes and serve as stops to limit the sliding movement of the leaf-turning rods when drawn over the book in setting the apparatus. The rubber buffers S, above referred to, prevent noise when the rods spring back to their normal position.

It is evident that the construction here shown and described may be changed inmany particulars which might suggest themselves to a skilled mechanic, and hence I do not limit myself to such exact construction, but consider myself entitled to all such variationsas come within the spirit and scope of my invention.

Having thus described my inventiomwhat I claim as new, and desire to secure by Letters Patent, is-

1. In a music-leaf turner, the combination of suitable slideways located at opposite sides, a transverse rod having slides fitting said slideways, respectively, spiral springs extending lengthwise of the slideways and acting against the slides, and means for holding and releasing the latter.
