HASKELL H. TIMMONS AND ELBERT L. SMITH, OF FREDONIA, KANSAS.

MUSIC-LEAF TURNER.

T 0 all whom it may concern:

Be it known that we, Hasknnn H. TLM- MONS and ELBERT L. SMrrH, citizens of the United States, and residing at Fredonia, in the county of lVilson and State of Kansas, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

This iny'ention relates to music leaf turners, and pertains especially to the class of spring operated devices for turning music leaves.

The object of the invention is to provide novel and peculiar construction and arrangement of the parts of a music leaf turner aflording means for operating the same either by hand or by foot pressure.

A further object of the invention is to provide a music leaf turner adapted to be operated either by hand, or by foot pressure and comprising a plurality of foldable and extensible arms operated by a pair of spring cont-rolled slidable levers connected with a pair of foot levers.

A still further object of the invention is to provide a pair of slides to each of which is pivoted a lever having a dog or pawl for turning a plurality of leaf turning arms, such slides being operated either by hand, or by foot pressure in turning the arms, and controlled by a pair of spiral springs for automatically returning the slides and the said levers into turning position.

A still further object of the invention is to provide a special casing for the ari'n-operating mechanism, specially shaped turning arms, cord and pulley connections within the casing and extending therefrom for operating such mechanism either by hand, or by foot pressure, and a protecting apron attached to and extending from the casing.

Various other objects, advantages, and improved result-s are attainable in the prac tical application and operation of the invention hereinafter to be fully described.

In the accompanying drawings forming part of this application: Figure 1 is a front view of the device with a portion of the protector broken away. Fig. 2 is a rear View of the rack. Fig. 3 is an enlarged section on the line XX Fig. 1. Fig. 1 is a bottom view of the casing. Fig. 5 is a-nelevation with the front of the casing removed. Fig. 6 is an enlarged cross section on the line Y-Y Fig. 5. Fig. 7 is a section on the line ZZ Fig. 5. Fig. 8 is an enlarged section Specification of Letters Patent.

Serial No. 645,404.

showing one of the lever-dogs engaging a turning arm with the latter as in the act of being turned. Fig. 9 is a perspective view of one of the turning arms partly broken away showing it partly extended. Fig. 10 is a perspective view of one of the slides with its lever or dog. Fig. 11 is a side elevation of the tripod head. Fig. 12 is a per spective view of one of the tripod legs, partly broken away, and its foot lever. Fig. 13 is an elevation of the casingfolded.

The same reference numerals denote the same parts throughout the several views of the drawings.

In carrying out our invention, we employ a music rack 1, having projecting members or extensible wings 2, for holding a protector sheet 2, stretched over the front of the rack so as to entirely cover the same and prevent contact therewith of the music or music book. Said protector is attached to an extension 3, of the back of the casing l. The hollow standard 5, of the rack has a pair of pulleys 6, and a tripod head 7, is attached to or formed on the lower end of the standard, and the tripod legs 8, are adjustably pivoted in such head by means of a slot 9, in the legs and pins 10, in the said head. The lower end of two of the legs has an ear 1!, to which is fulcrumed at 13, one end of a foot lever 14;, the other end of the lever is connected to these legs by spiral springs 15, and the levers have a footpiece 16, projecting therefrom in convenient position to apply toot pressure for depresing the levers, and the function of the springs is to retract the levers. Said levers have a hook 17, to which are attached eyelet straps 18, for connecting pull lines or cords 2O thereto. The cords 20, are connected with the pulley cords 21, by means of hooks 22 and eyes 23. The cords 21, extend over sheaves or pulleys 24:, ournaled in the casing and are attached to stems 25, of the slides 26, working in grooves 2?, upon the inner sides of the casing. Said stems are operated through and controlled by spiral springs 28, butting against guide brackets 29, and against plates 30, which connect the stems with the slides. The slides each have a lever 31, pivoted thereto at 32, and such levers are controlled in their movement by a plate spring 33, attached to the slides. The levers 31, are provided with a pawl or dog 34:, controlled in its outward movement by a spring 35, and the free end of said dogs or pawls is provided with a hook head 36, adapted to engage the pivoted end of the leaf-turning arms 37, for lifting and turning said arms successively from one side to the other. The arms 37 are pivoted on arm shaft 38, fixed within the casing.

The arms 37, all being of the same construction only one of them will be herein described in detail; such arm is L-shaped, the short member 37 of which extends into the casing and is provided with a pair of cars 39, for mounting the arm on the shaft 38, and the long member of the arm 37, has a linger 4-0, pivoted thereto and foldable thereupon by means of a col'inecting link ell, and bar 42, the free end of the finger being provided with a leaf grasping clamp \Vhen the arms 37, are not in use they may all be thrown to one side of the shaft 38, and held against the back or extension 8, of the casing by means of a keeper 44-. The said back extension 3, is provided with pins 45, which form a rest for sheet music or music books.

The means for operating the foregoing described mechanism by foot pressure that the same may turn the arms 37, has been described, and in order to operate said mechanism by hand, cords 443 are attached to the end of the stems 25, and extend over guide sheaves L7, journaled in the casing and project through the bottom of the casing where such cords are provided with hand knobs L8.

The casing is divided centrally into two parts which are hinged together at 49, so as to form an opening L9, and said parts are secured in lengthwise, operative position by means of a latch 50, or other similar device, which will permit the casing parts to be folded one upon the other when not in use, or for packing and storing, or for transportation. The bottom of the casing is provided with a pair of thumb-screw clamps 51, having followers or washers between which, projections of the music rack are clamped for connecting the casing to such rack in operative position.

The leaf turning arms may be operated either by applying foot pressure to either of the foot levers for sliding one or the other of the slides, and such sliding movement will pull and raise the dog lever with one of the leaf turning arms (for example one at the right of the rack) hooked in the dog head for raising said arm in circular movement and swing or throw it over its pivot shaft, so that said arm will fall by gravity into proper position at the left of the rack. The same operation and result is accomplished by pulling the hand knobs, and upon releasing such pull or the foot pressure, the spiral springs 28, will automatically return the slides so as to drop the lever, and permit the dog head to fall under or hook a11- other leaf turning arm.

It will be observed that the foldability of the arms and of the casing will permit the device to be conveniently set up and removed from place to place as may be desired, without other arrangement or manipulation thereof, except the clamping of the same to the rack, connecting the hook and eyes, and then hooking the straps to the foot levers; and thatsuch hooking of the straps may be varied according to the tension of the foot springs and the springs 28, so as to produce proper and desirable working of the parts. hen the leaf turning arms are in operation, the arm keeper is turned parallel with the casing.

It is obvious that the casing may be clamped to the music rack or holder of pianos and organs, in which case the leaf turning arms are operated by the hand knobs and their cords.

It will be understood that various changes or modifications may be made in the manufacture and practical application of the in vcntion, within the scope of the appended claim, and that we do not wish to be understood as limiting ourselves to any particular size, shape or material, nor to any particular number of leaf turning arms.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is:

The combination, with a music rack, a tripod support for the rack, and a music leaf turner com 'n'ising a casing attachable to the rack, leaf turning arms onrnaled in the casing and projecting therefrom, and mechanism contained within the casing for turning the arms, of means for operating said mechanism comprising a pair of lovers fulcrumed to the legs of the tripod and having hooked ends, a foot piece projecting from the levers between the fulcrum and the hooked end of each, cords working through the head of the tripod, adjusting straps conneeting the cords with the lovers, spiral springs attached to the hooked ends and to the legs of the tripod so as to hold the levers and the straps substantially parallel with the legs, and. cords working through the casing and connecting the strap-cords with said mechanism.

In testimony whereof we afiix our signa tures in presence of two witnesses.
