MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 343,663, dated June 15, 1886.

Serial No. 180,414. (No model.)

specification, reference being had therein to the accompanying drawings.

This invention pertains to improvements in combined book and sheet-1nusic holders and leaf-turners, the same being adapted for use with musical instruments of any character, and to accommodate books or sheet-music of whatever size, as well as to readily permit of the turning of the leaves without the immediate application of the hand thereto,and about with the movement of the hand of the player as that required in playing the musical instrument, which are some of the advantages of my invention.

The invention therefore consists of the combinations of parts, substantially as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a front elevation of my invention, the rack being shown also in dotted lines ex tended, varying its holding capacity. Fig. 2 is a plan View. Fig. 3 is a rear elevation. Fig. 4 is a vertical central section thereof. Fig. 5 is a horizontal section taken immediately below the upper base piece or board, showing in plan view the leaf-turner arms with their fingers and springs, and the armretaining and tripping devices. Fig. 6 is an inverted view of the invention, and Fig. 7 is an enlarged detached view, in side elevation, of the leaf-turning, arnrretaining, and trip ping devices.

In the embodiment of my invention I arrange above a bottom or lower base board, A, a second board, A, secured upon transverse cleats or bars a a, fastened upon the board or base A, the front or face edges of which boards may, for the sake of finish or ornamentation, be configurated, the object of the duplication of which will appear farther- B is a casting or bracket, having an upper curved or semicircular portion, formed with rearwardly and outwardly extended portions,

in turn formed with downward extensions, which are bolted or screwed to the rear edges ofthe lower base-board, A. The bracket or casting B is thus adapted to overhang and stand about centrally of the boards A A, as a preferable position, and is formed or provided at the center of its semicircular portion at the front side with a socket or sleeve, 1), and from said sleeve or socket depends a plate, into which works a thumb-screw, Z), the inner end of the tapered portion of the head of which screw forms a shoulder, the function of which will be presently seen.

C is the sheet-music or book rack or holder proper, which comprises a series of diagonal ly-crossing slats or bars connected together after the fashion of lazy-tongs, and connected fixedly at its lower end to a central standard,C, but has a sliding connection near its upper end with said standard, whereby the rack can be extended or contracted, in order to vary the size thereof according to the size of the sheet of music or book to be accommodated or held thereon. The connection between the rack and standard is effected at the upper end by a headed bolt or rivet, (1, projecting from a plate, (2, and passed through a slot, 6, in the standard and through the rack, said plate (1 being fastened to the rear side of the standard, and at the lower end by analogous means, the rivet (1 also passing through the slot 0 of the standard and the rack, and

projecting from a plate, 11', sliding upon the rear side of the standard.

D D are clasps or binders, which are so dis posed upon the rack C that the rivets d d aforesaid are further utilized to secure them in place, and which clasps or binders are each constituted of a springinetal split tube, the longitudinal edges or lips of which tube are curved or turned inward, to prevent the same from tearing the sheet-music which they are designed to hold, the back edge of the music being inserted into said clasps or binders through the slots or spaces between the longitudinal edges of the latter. Beyond the bottom or lower edge of the rack project horizontal pins or stiff wiresff, being fastened to the rear side of the rack, which pins or wires are arranged a suitable distance apart and serve to support or hold a book, when the music is in that form. Arranged upon the rear side, of the standard 0, and in a plane above the rack O,are'two spring-arms, E E, having slight downwardly-projecting outer ends, which are I brought into requisition when it is required to hold the leaves as against turning in at the I upper corners or leaving their places, thesaid 1 arms being sprung forward,and so as to cause the slight projections at their free ends to rest upon the leaves of the book or the sheet-i music, as the case may be. Theinner ends; of these arms are pivoted to the cross-piece of an approximately T-shaped plate, 9, with the lower end of its vertical portion or stem riveted to a plate, arranged to move in align" ment with the slot 6 of the standard 0, and connected to the rack, to permit it to move; therewith by the sliding rivet d of the rack. 1 The cross 'piece of the plate 9 isalso clipped, as at g, to the standard 0, which "clip is; adapted to slide upon the latter, and from the inner side of said cross-piece of the plate projects a rectangular bar, which extends through the slot 'e'o'f the standard and an angni la'r closely-fitting slot, 9, in the rear part of i the 'cli p g". Beyond the clip 9 the bar 9 is formed into a screw, and upon the latter is; fitted a thick washer, (preferably wood); and a milled thumb-nut, g, by the screwing up of which not both the spring-arms EE-and the rack O are firmly held at their point of adj ustm en t. g The rack, with all of its above-described adj'unctive parts, is held or sustained in an upi right position by the insertion of the lower end of the standard 0 into the socket or sleeve 1), previously described, and a'l lowingij its'slot to receive the screw 1), and then by turning the screw until the shoulder of its] head is brought against the standard the ia'tter will be firmly secured in position.

F F are the series of leaf-turning arm's,'w%hich are a'rranged horizontally between the boards A A",and upon a common pivot or axis, h, secured at its ends to and about centrally of the said boards. These arms are each .pr0- vidcd at its free end with two fingers, F, be, :tween which a leaf or sheet is received and carried in turning the same. These ends of I the arms are bent or stand vertically, as at 13, to secure the proper disposition of the tin-- gers with relation to the leaves or sheet of:

\ music; also, in order to prevent the interferar'r'angedbetween the two boards A A.

ence of the action of one with the other, the arms-are varied successively in length, whilev the vertical portions iiof the more distantor outer ones are oflset, as at i i, horizontally, to j adaptihem for engagement with the further;

removed leaves. The inner'ends of these arms are each flexibly connected 'by a plate, 4", and

The

outer ends of the springs G are connected to a common lpin passed through and fastened to the plates H.

I is the leaf-turner-arm retaining device,

angled bracket or flange, j, projecting from one side of a downward and forward extension, j, thereof, which bracket or flange has its vertical portion let into and fastened to the front edge of the board, while its horizontal portion fits against the underside of the board. The forward and downward extension, j, of the retaining device I is also extended upward at the frontend of the slot of said device, to prevent-the leaf-turner arms from being forced out of said slot by the action of their springs, while the lower .end of said extension j is provided with an inwardly-projecting ar-m,j extending under and partially let into a recess, "k, in the lower side of the base-board A, the purpose of which will appear further on.

J is the leaf-turne'r-arm tripping or releasing device,which comprises a slide or the trip proper, J, arranged to move upon the forward extension, 9, at its one side, and upon or in contact with a vertical shoulder or guide, j, formed upon said extension, said slide or trip having a headed pin or projection, 70, fi-tted to have movement in a vertical slot, If, in said extension '9', "to also guide and :limit the movement of the trip or slide when actuated. The trip or slide is arranged in alignment with the opening of the slot of the arm-retaining device I, and is actuated so as'to bemoved pastthe forward end of said slot and to the opening of the slot, in order to separatelylift the leaf-turner arms 'outof the retaining device ;I by a lever, K, let into a channel or re- 'ces's in the under side of the base-board A and pivoted to the arm j, and to the said slide or trip proper, J. The inner end of the leverK is both acted upon by aspring, L, to hold the trip or slide normally depressed,and connected to a'second lever, M, which spring is also let into the under side of -and fastened to the "board A. The lever M is likewise sunk and pivoted in a recess orchan'nel, Z, in the under side'o'f the board A,sufiiciently wide to permit of an axial movement, aswell as of movement upon its pivot, of the lever, to readily accommodate the arm M (with which the lever is prov-ided)'to'theposition of the hand of the player of the musical instrument. Said arm .Mfexte'nds about at a'right angle from the lever,

andforwardly and downwardly, and in practice toward the key-board of the instrument, and closely to the hand of the player, in such contignity as to permit of the actuation of the lever-arm in operating the tripping-device to turn the leaves of the book or sheet-music by aboutthe'sa me'movement ofthehand as that required in playing the instrument, thus'en abling 'the'same to "be readily or quickly operated, and

without any loss of time or break in the music, as would be experienced in the use of the hand directly in turning the leaves or music. The lower end of the lever-arm M is provided with an eye or socket, m, having an adjusting and holding screw, m, which eye is designed to receive a wire rod, N, held therein by said screw, which rod, however, is only brought into use in the event the lever-arm M should fail to permit of its being adapted to be actuated by the hand of the player in the manner just described. The flexibility of the rod (being of wire) permits of its being readily bent, if required, to effect the result or end just named in connection with the lever-arm M.

The contrivance as above described, as an entirety, is connected or adjusted to the ledge or cleat at the front of the musical instrument, just above the key-board, by clips or clamps a, secured to the ends of the base-board A, as shown in the plan view, Fig. 2, and adapted to he slipped and clamped upon said ledge or cleat by means of the binding or clamping screws and nuts 02, the screws working in the clamp or clamps near the inner connected ends of their plates and in nuts, as seen in the latter or same figure. This contrivance can be applied also to brass instruments played by the mouth, or wherever book or sheet music is used, and is readily constructed, simple, and cheap.

From the foregoing the operation is obvious, it only being necessary, with the leaves or sheets of the music placed between the fingers of the turner-arms and the latter placed in the retaining device, to actuate the leverarm M or the rod N, as the case may be,when

the said arms will be lifted out of the retaining device, and by the action of their springs be sprung to the opposite side of the baseboards A A, thus effecting the turning of the leaves, which of course is done as the pages are wanted.
