.T0 all wil/0712, it may; concern.-

Beit known that l, EDWARD BARRACLOUGH, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Music-.Leaf Turners, of which the following is a specilication.

This invention relates to that class of musicleaf turners which hold the piece of music in place and turn the leaves by spring-actuated leaf-holders held against the tension of their springs by a tripping device, which is actuated by the linger of the performer to release a holder,when, by the retraction of its spring, it will tlop over and carry the leaf with it.

The object of the invention is to simplify and improve the construction of the tripping device, whereby it is rendered more efficient and durable in use, and not liable to get out of repair. p

A further object is to improve the general structure of this class of devices,whereby it is economical iu cost7 easily kept in repair, and readily managed by any performer.

Vith such ends in View the invention consists in the novel construction, arrangement, and combination of parts, more fully hereinafter set forth and particularly claimed, and shown in the annexed drawings, in which- Figure l is a front view ofa device of my coustruction embodying my impro vement-s. Fig. 2 is a side View ofthe tripping lever and pawl. Fig. 3 is a longitudinal section through the tripping lever and pawl. Fig. 4 is a plan view o1" the tripping-lever detached and with the pawl removed. Fig. 5 is areverse or bottom view of the pawl. Fig. 6 is a side view of one of the leaf-holders, and Fig. 7 is an end view. Fig. S is a cross section of the musicholder. Fig. 9 is a side view of the lower right-hand corner of the music rest or stand, showing the tripping device in elevation. Fig. l() shows the slotted bearing for the ratchet-bar. Fig. ll shows the spring for act- Fig. 12 is a detail uating the music-holder. of the tripping device.

The base or plate Arepresents any suitable support or rest for the music, and forms a means for holding the operating parts in their relative positions.

The music-holder B is made of a strip of spring metal folded or bent into a nearly cylindrical form, leaving a space between the adjacent sides, which approach, forming the opening 3, through which the piece of music projects. ln order that the side edges may not do injury to the piece, they curve to each side of the opening. has the upper corners, 7), turned back, presenting a moutlnwhich receives t-he lower edge of the piece of music and guides it into the opening B'. This is essential, as it facilitates the insertion of the piece within the holder. A plate, O, having flanges or lugs c projecting therefrom, is located beneath the holder, and supports a rod, D, in line with the musicholder. This rod forms the pivotal support for the leaf-holders E, the inner ends of which are bifurcated and bent around the rod, leaving a space, c, between the bifurcations c. Coil-springs F, mounted on the rod within the space between the bifurcations d, and having their opposite ends entering and bearing the one on the side ofthe holder, the other on the plate, are always under tension, to keep the holders in place down upon the rest A on the left ofthe holder. The outer ends of the holders are provided with clips leomprising two bars, between which the leaf is held.

The tripping device comprises a keeper or base, G, a ratchet-bar, H, supported in lugs extending from the base, a tripping-lever, l, paw] J, and fulcrum or pivotal support M for the lever. The ratchet-bar is mounted in lugs or iianges g,projecting from the base or keeper,

and is ofa length to be extended across theV clips of the holders and keep them down upon the right-hand side oi the music-rest. The teeth 'It extend downward, and are of a length to correspond with the stroke of the lever, which is limited in its forward movement by striking against one ofthe lugs ofthe keeper, and in its backward movement by a stop, L. The lever is pivotally supported at one end upon a stud, M, and a coil-spring, N, surrounding the stud,having one end engaging a lug, n, on the side thereof, and its other end engaging a lug, n', Fig. 9, near the end ofthe lever, carries the latter back to its normal position against the stop L, after being actuated to move the ratchet-bar forward for releasing one of the holders. It is provided with a de- The top of the holderv ICO 1o reciprocating movements.

ver, and is held in place by a screw, O, cx- 5 tending through a slot, j.

Exteusionsj, projecting from each end of the pawl, bear upon the lever on each side of the depression, and

slotsjL in theends of said extensions receive the pins i and give direction to the pawl in its The rack-bar is located between a side of the depression and the end of the pawl, which end j is beveled to form a tooth for engaging with the' ratchetbar during the forward stroke of the lever and carry it with it, thereby releasing one of the holders. The lever, being free,will return to its iirst or normal position,and be in readiness to advance the ratchet-bar another step, thereby releasing another holder. The pawl durzo ing the return-stroke of the lever rides the teeth of the bar, which is held simply by the friction of its bearings, which are slotted to take up for wear, as most clearly shown in Figs. 9 and 10. A coil-spring, p, interposed between the pawl opposite its beveled end and the side of the recess in the/lever keeps the tooth ji in contact with the rack-bar. It may be seated in a socket, p, formed in either the lever or pawl, or both, as desired.

3o Freni the foregoing description the operation ofthe device will be readily understood by one conversant with the use of similar devices. The ratchet-bar may be moved in its bearing by disengaging the pawl from its teeth,

which may be done by grasping a knob, F,

and pulling against the tension of the spring p. The ratchet-bar is moved by means of a knob on its cud, and a pin, h', on its opposite end forms a stop to prevent its displacement 40 from the keeper.

ratchet-bar mounted in and free to slide through said lugs and retain theholders against the tension of their springs, a lever pivoted at one end and provided witha depression between its ends, pins extending from the lever on each side .of the depression, a

pawl seatedin the depression, and having end extensions overlapping the lever on each side of the depression and slotted to receive the pins, and a stop to limit the backward movement of the lever, substantially as described.

2. The herein shown and described tripping device for 'music-leaf turners, comprising the following elements in combination: a keeper having lugs, Va ratchet-bar mounted in and free to slide through said lugs, a lever having a depression between its ends and pivoted on a stud at one end, a coil-spring surrounding the stud and connecting it with the lever, pins extending from the lever on each side of the depression, a slotted pawl seated therein, and having a beveled end forming a tooth for engaging the teeth ofthe rack-bar, and provided lwith end extensions to overlap the lever on each side of the depression, said ends being slotted to receive the pins, a bolt passing through the slot in the pawl for holding it in place, a coil-spring interposed between the end of the pawl and a side ofthe depression, a'knob projecting from the pawl, and a stop for limiting the backward movement of the lever, substantial] y as set forth.

3. The combination ofthe vertically-inclined stand-plate A, having leaf-turning devices,with a musieleaf holder secured to said plate, consisting of the bent stri-p of spring sheet metal B, flaring at its meeting edges B and at its upper end, Ig, whereby the sheets of music are quickly inserted and held within the holder, as shown and described.

4. In a inusic-leaf turner, the combination, with a baseplate having lugs and a rod held between the lugs, of a leaf-holder provided wit-h a clip at one end, and havingits opposite end bifurcated and bent around the rod, having a space between the bifurcations, anda coil-spring mounted on the rod between the bifurcations, aud having its ends extended, the one bearing on the holder, the other on the base, substantially as shown and described.

5. The combination, with the pivoted springactuated leaf-turners, of the keeper or base G, having lugs c, provided with the split bearings, the slide ratchet-bar H, tted within the split bearings, and the pivoted lever T, having a spring-actuated slide-pawl, whereby the ratchet-bar is held by the friction of its split bearings against the non-acting movement of the slidepawl, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
