Music-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 728,000, dated May 12, 1903.

Application filed February 26,1903. Serial No. 145,217. (No model.)

To all whom, it may. concern:

Be it known that I, WALLACE T. PAXSON, a citizen of the United States, residing at Washington, in the District of Oolumbia,have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

My invention relates to improvements in leaf-turners for sheets of music and similar publications; and the object is tosimplify and improve the existing art by providing an implement of the kind named and for the purposes intended which is simple in construction, eficient in operation, and durable in use.

The invention embodies a revoluble base, a toothed standard in the base, and upper and lower arms extending horizontally from the standard and adjustable vertically thereon.

The invention further consists in the novel construction of parts and their arrangement in novel and operative combinations, as will be hereinafter fully specified, and the novelty claimed willbe particularly pointed out and distinctly determined.

I have fully and clearly illustrated the invention in the annexed drawings, to be taken as a part of this specification, and wherein- Figure 1 is a view in elevation showing the complete device or improvement set up ready for use. Fig. 2 is a detailed view of the revoluble pulley or sheave in which the base of the standard is secured and showing the means for turning the pulley. Fig. 3 is a detailed view of the lower plate of the housing. Fig. 4 is a detailed edge view of one of the leaf-holders, showing the spring which engages over the leaf and the bracket which fits over the standard. Fig. 5 is a detailed view showing the leaf-holders and the bracket separated to indicate their particular construction. Fig. 6 is a detailed view of the upper plate of the housing, showing slots as a means of fastening the device in position.

In the drawings similar reference notations indicate the same partsappearing in the several illustrations.

Referring to the drawings, 1 and 2 designate, respectively, the upper and lower plates forming the housing in which the operatingpulley is journaled. The plate 1 is formed with perforations to take in the pintles or journals or rollers. The inner portion of plate 1 is angular, as shown, and provided with opened slots 4, which are designed to take under screw-heads and hold the device in poin the plates, as indicated.

The housing-plates are connected together i by sleeves 9 and rivets, as indicated. In the hub of the pulley 8 is made an angular opening 10, wherein the end of the standard is seated and held when the device is set up andv in use. In the groove of the-pulley is arranged and secured, as by a staple 11, a pulloord 12, by which the pulley may be turned the desired distance in either direction.

12 designates the standard, which is made of suitable metal, with its lower end framed to fit and set in the aperture 10 in'the plates. The standard may consist of two sections or parts of the same length together, as at 13, and on the one edge is framed with notches 14, which are engaged by end of the extension on the end of the leaf-holding bars.

15 designates looped metal straps, which slidingly embrace the standard, so as to be adjustable up and down thereon, as indicated in the drawings. 7

16 designates the leaf-holding bars, formed at their inner ends with a portion bent at approximately right angles to the main'bar, as at 17, and then extended rearward, as at 18, the end of the part 18 being reduced so as to readily engage in the notches in the standard. The leaf-holding bars have the angular part 17, pivotally mounted between the ends of the straps 15, and to prevent the leaf-holding bars from hitting below horizontally a stopping is arranged across between straps, against which the extension 18 lodges, as shown in the drawings.

-20 designates spring-rods, secured to the leaf-holding bars at their inner ends and positioned to lie parallel with said bars and partly circular with radial ears 3, provided with their inner faces against the faces of the bars, their outer ends being unattached, so that a leaf of the sheet may be readily slipped in between the bars and the springs thus held ready to be turned over.

To utilize the device, it is secured in position convenient for manipulation. The leafholding bars may then be adjusted to the desired positions to secure the leaf or leaves, and then the sheet is arranged between the bars and the springs and the device is ready for manipulation, which is accomplished by simply pulling on one of the strands of the pull-cord with force enough to rotate the grooved pulley and turn the standard in its axis, which movement will swing the arms and turn the sheet over with the reverse side or face exposed to visual observation.

Having thus described my invention, what I claim, and desire to secure by Letters Pat-- ent, is-

1. The music-leaf turner comprising a revoluble base, a notched standard in the base, and upper and lower pivotally-supported arms extending horizontally from the standard and engaging the notches in the standard to hold them in position.

2. The music-leaf turner eomprisinga housing, a grooved pulley journaled in the housing, means to turn the grooved pulley, a notched standard having its lower end secured in the hub of the pulley, straps slidably embracing the standard, leaf-holding arms pivotally mounted in the ends of the metal straps, a stop-pin in the straps to engage the ends of the arms to hold them in horizontal position, and leaf-holding springs bearing on the arms, substantially as described.

In testimony whereof I have signed my name to this specification in presence of two 40 witnesses.

WALLACE T. PAXSON.
