ALIPIO C. BARTHOLO AND MANUEL PERRY, 0F NEW BEDFORD, MASSACHUSETTS.

MUSIC-LEAF TURNER.

Application filed February 15, 1921. Serial No. 445,124.

To au whom, it may concern:

Be it known that we, ALIPIo C. BARTHoLo and MANUEL PERRY, citizens of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Music-Leaf Turner-s, of

Va novel means for the mounting of music in such devices, whereby expensive, heavy or awkward clamping or securing devices are rendered unnecessary. A further purpose is to give an improved construction in turning arms in such an appliance. A still further aimL is to give a novel and desirable struc-V ture in the base element and :mounting for the leaf turning elements.

Additional objects, advanta es and features of invention willappear rom the construction, arrangement and combination of parts hereinafter set forth `and shown in the drawings, wherein Fi-gure il is a front elevation of a turner embodying our invention shown in open position, with sheet music engaged therein.

Fig. 2 is a horizontal sectional view showing the turning arms in plan, with the clips removed, the evice being closed.

Fig. 3 is a fragmentary top view showing music engaged with the device,

Fig. 4 is a fragmentary front elevation of the music securing pivot element,

Fig. 5 is a fragmentary horizontal sectional view lookingr upwardly, showing the last mentioned element,

Figs. 6 to 13, inclusive, are views of the turning arm blanks represented in the order of assembly from bottom to top.

Fig, 14 is a fragmentary vertical cross section showing the mounting of the turning arms,

Fig. l5 is a perspective view of one of the arms and clips.

There is illustrated a music leaf turner comprising a backing portion which is adapted to be closed in the form of a book. It includes a vertical central back piece 20,

formed of sheet metal, rectangular in cross section and oblong transversely, to the back surface of which there is secured by suitable adhesives a flexible fabric 2l which projects beyond the vertical edges of the back piece and has secured to its edge portion respective cover pieces 22, which may be of liiull'rboard or other suitable material. The outer surfaces of the Whole are covered with a suitable ornamental. material 23, such as leather, or paper.

he back piece is in the form of a rectangular tube, and upon this a short distance from its upper end there is mounted a combined music retaining clip and pivot formed of wire,includingabase eye portion 25 through which a screw 26 may be engaged to secure the clip upon the back 20. From the eye the wire is recurved to receive a second mo-untin screw, and then extended downwardly an form a spring loop 27.V From this loop the wire is continued to provide a pointed semicircular music-piercing piece 28 disposed in a horizontal plane at right angles to the plane ofthe eye and the spring loop before mentioned. The extremity of the piercing member extends inwardly at a distance from the eye 25 and a short distance into an aperture 29 in the back. The construction of this device is such that by grasping the member 28 and drawing outwardly thereon, the point may be withdrawn from the apertures 29 sufficiently for the insertion of the upper left hand corners ofmusic leaves thereunder, and release of the piercing member will permit it to ierce the sheets presented thereunder, whlch may then be moved pivotally, sliding upon the piercing member. If desired, the music may be perforated suitably to t loosely upon the member 28.

A short distance above the lower extremity of the back member 20, a horizontal ear 30 is pressed from its forward side, and a short distance therebelow a parallel similar ear 31 is thrust forwardly into vertical alinement therewith from the back portion of the back member 20. A pintle 34.- is engaged through the ears 30 and 31 and screwed into a cylindrical element 35 below the ear 31, to form a support for the leaf turning arms.

Eight leaf-turning arms, numbered 36 to 43 inclusive are illustrated, having apertured horizontal ears 44 around the pintle, snugly held between the ears `recurved upwardly to 30 and* 31" of the back 20. Thearms are ot' thin" sheet metal disposed in vertical planes and the ears 44 are spaced on the heels 32 ot' the arms, a proper distance to allow nesting of the arms in a vertical horizontal plane. The arms 36 to 43 are progressively lengthened, and provided at their extremities with out-standing ears 46 between which clip elements 47 are secured,y whereby a sheet of music may be held in fixed relation to the respective arms. At the outer end of said arms upwardly extending clip lugs 47 are formed integrally therewith cooperating with the clip elements 47 so that a sheet of music may be held therebetween. The clip elements 47 mafv be spring-pressed in an familiar Way. It should be noted that tlie clip elements have a finger portion extending downwardly therefrom which serve both as a clip operating device, and as a means by which the arms 43` may be operated for shifting music, as may be readily appreciated from Fig; '1 and Fig. 2. At their inner ends, the arms are formed with heel portions SQ'extcnding downwardly from the respective arms having vertical1 edges adjacent the horizontal ears 44 and adapted to bear either upon the next adjacent lower ears 44, or upon the supporting element 35. The leaf-'turning arms are'tlius held securely elevated at their outer partis.

The arms are in the form of plates allY stamped" from sheet materiali and are arrangedwith their ear portions 44 successivelyY lower, iny numerical order, as shown inl Figures 6 to 13, so that they may lie closely in nested relation when 'cl'o'sedl` permitting closure of the device' readily. y

In use, sheet music is adjusted in the device as shown in Fig. 1, and leaves thereof clamped to respectivel arms by means of the clips 47, as shown and; indicated. AllE of "the leaves and arms are first positioned to the right, as will be understood, and with the parts in this positiomeaell Qf'ftlie `clips 47 is in spaced relation" with, al'ldL a? little in advance of the one adjacent so that it may be readily engaged manually without Yliability of operating more than one at a time, permitting manual turning of the leaves with either hand with great certainty7 and rapidity.

What is claimed:

l. In a music-leaf turner, a back element comprisingr a tube rectangular in cross section, music retaining' means ont the front thereof, the front part' of the] tubev at the lower end being turned outwardly to form an upper pivot ear, the rear part of said tube being turned in a similar direction at a lower level to form a lower pivot ear, the sides of said tube being extended a distance below the last named ear, means engaged withy the tube to support it above a music rest, a pintle engaged in said ears, and musicturning arms pivot'ed thereon;

2. In a device of the charactetkdhscribed, an improved music turning arm comprising a plate of sheet metal having a'- pivot ear formed at one end thereof and turned in' a plane at right angles toA the verticall rn'e` dial plane'of the* plate, and a heel element extending downwardly therefrom* integral,"

andi in al vertical plane with, thebody,- said platei having an upwardly extending clip lug"V at the outer end, and' parallel rVertical ears adjacent thebase of the lug, and# clip' device pivoted between said'ears Haiti an* operatingiportion extending downiiiardl 'bv which theI clip may bey operated, an which tlleyarms may also be turned.

In testimony whereof We have alli'x'ed our` signatures in presence oft-wowitresses.
