MUSIC-LEAF TURNER.
SPECIFICATION forming part Of Letters Patent NO. 651,1 10, dated June 5, 1900.
Application filed June 28, 1899. Serial No. 722,112. (No model.)
To all 2071 0127, it may concern:
Be it known that I, CLYDE N. FRIZ, a citizen of the United States, residing at the city of Charleston, in the county of Charleston and State of South Carolina, have invented certain new and useful Improvements in Music- Leaf Turners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to an improved musicleaf turner especially designed for use on pianos and organs, but also suitable for musicstands, and intended to be made adjustable to the ledges of music-racks as now found on the various makes of pianos and organs.
The object of my invention is to provide a music-leaf turner that will be absolutely infallible in the action of the escapement device controlling the leaf-tu rnin g arms and one that will give a minimum amount of trouble in attaching to the instrument and in arranging the music.
My in vention consists in features of novelty hereinafter fully described, and pointed out in the claims.
Figure I is a perspective View showing my improved leaf-turner with part of the leafturning arms set in position for use and one arm tripped. Fig. II is a vertical longitudinal sectional view taken on the line II II, Fig. III. Fig. III is a vertical transverse sectional view taken on the line III III, Fig. II. Fig. IV is a horizontal sectional view taken on the line IV IV, Fig. II. Fig. V is an enlarged detail perspective view of portions of one of the leaf-turning arms and the coinciding portion of the finger-lever whereby they are tripped. Fig. VI is a detail view showing in section a portion of the top of the turner-case and in edge view the push-rod carried by the musicholding clamp. Fig. VII is a detail view of one of the adjustable clamping members by which the turner is secured to a music-rack.
1 designates, the case in which the operating parts of the leaf-turner are mounted and upon which the music-holding clamp is supported. This case is illustrated as closed at its rear side and is provided at its front side with a horizontal slot 2, extending from end to end of the case. The case 1 is designed to be attached to the ledge of a music-rack of a piano or organ by angle members 3, connected to the case. The members are provided with spring-arms 4 and 5 at their respective ends, preferably covered with a padding 6 of rubber, felt, or other suitable material. The spring-arms 4 and 5 overlap and are adapted to bear upon opposite sides of the ledge portion of a music-rack, and the spring-arm 5 is adapted to be sprung toward the spring-arm 4. by a set-screw 7, turningin the member and case, for the purpose of adjusting the space between the spring-arms to accommodate them to the thickness of the portion of the music-rack which they embrace. The springarms are provided with coinciding apertures (see Figs. I and VII) through which a screwdriver may be inserted to move the screw 7 at will. The members 3 may be attached to the under side of the case or the rear thereof, according to the formation of the rack to which they are applied.
The music to be held and turned is placed above the case 1 and inthe rear of a vertical post 8, extending downwardly to the bottom of said case. In the rear of the post Sis a clamp-bar 9, that is backed by a spring 10, secured to ,an upright 11. The spring 10 serves to hold the clamp-bar 9 forwardly to retain the music sheet or book between said clamp-bar and post 8. The lower-end of the clamp-bar 9 extends through a slot 1 in the top of the case 1, (see Fig. V1,) from which a push-rod 12 extends forwardly'through-a slot in the front of the case and is provided with a finger-piece 13 and a notch 14, adapted to receive the wall of the case when the pushrod is pressed inwardly, and thereby hold the clamp-bar 9 in retracted position. WVhen the push-rod is released, the spring 10 carries the clamp-bar forward against the music sheet or b'ook'placed back of the post 8.
15 designates a cylinder seated vertically between the top and bottom of the case 1. This cylinder is provided with a series of vertical perforations 16, either of which is adapted to receive the post 8, which, as stated, extends through the case to its bottom.
17 designates the leaf-turning arms, the inner ends of which are of disk form and encircle the cylinder 15. Attached at one end to each arm is an individual spring 18, each one of which laps around and is connected at its opposite end to the cylinder 15. The tension of the springs 18 is rendered of the desired degree according to the position in which the cylinder 15 is held with relation thereto by the post 8 extending therethrough in one of the apertures 16 to maintain the cylinder in fixed position, the cylinder being adjustable on the post and held immovably. The inner end of each turning-arm is separated from that of the arm adjacent thereto by fingers 19. (See Fig. IV.) The outer end of each leaf-turning arm is provided with an upright finger 20, and pivoted to a bent extension 17 on each arm is a clamp-piece 21, provided with tongues 22 and 23. The inner tongue 22 is adapted to engage the lower edge of the arm 17 toprevent the clamp-piece 21 from extending too far down. By referring to Fig. 1V it will be seen that the outer ends of the leaf-turning arms, to which the clamppieces 21 are pivoted, are bent at an angle to the main bodies of the arms, thereby causing the bodies of the clamp-pieces 21 to receive an inclined movement with relation to the plane of the leaf-turning arms as they come in contact with and lie flatly against the upright fingers 20, holding a sheet or leaf of music between the two parts. In other words, by reason of the outer ends or extensions 17 of the arms 17 being bent at an angle to the main portion of the arms the clamp-pieces 21, which are pivoted to these extensions, are also disposed at an angle to the upright fingers 20, so that when said clamp-pieces are swung on their pivots their first approaching edges will become disposed at an angle to the' fingers 20, and as they are pressed against the fingers 20 the clamp-pieces will be caused to twist toward a parallel with the upright fingers to clamp the music-sheet between the two parts. The more force used in pushing the clamp-piece 21 into position the more tightly, as a consequence, will the sheet or leaf be gripped.
The leaf-turning arms are adapted to be held against the tension of the springs 18 by the following-described parts: 2t designates a finger-lever projecting through an elongated pocket 25 in the case 1 (see Fig. I) and provided with pivotal connection to a socketpiece 26 within the case, said socket-piece being hinged to a bracket 27, projecting from the case on its interior. The finger-lever 24E is arranged to partake of a lateral swinging movement in the clamp 21 and is adapted to be moved vertically by the socket-piece 26, pivoting in the bracket 27.
Connected to the finger-lever is a spring 28, that also connects to the case 1, (see Fig. II,) the said spring being designed to exert an upward pull on the finger-lever. On the finger-lever 24 is a stop-piece 29, and located a short distance from the said stop-piece and also on the finger-lever is an upright hook 30. Each of the turning-arms is provided with a recess 17 in its under side and provided with a tongue 17 having a beveled upper edge extending part way across said recess, but leaving a space between its end and the opposing end of the recess. WVhen the leafturning arms are thrown from the left into the position seen in Figs. II, III, and IV, they each come in contact with the stop-piece 29 and riding against the inclined edge of said stop-piece force the finger-lever 24 to the left and pass behind said stop-piece, and the spring 28 immediately returns the finger-lever to its normal position, as seen in the drawings. The next arm being brought around is carried into the same position as the first past the stop-piece 29, and the first entering arm is moved past the upright hook 30, so thatitisengagedthereby. Theturning-arms may thus be swung into position under tension for the reception of the music-leaves being moved either one at a time or collectively, and when in such position all but the fore most one will lie back of the hook 30, while the foremost one will rest between said hook and the stop 29. When the finger-lever is depressed, the stop 29 is carried downward, moving it out of the way of the tongue 17 of the turning-lever, thereby freeing the foremost lever and permitting its escape to turn and carry a music-leaf. At the same time the hook 30 moves with the finger-lever and catches the next succeeding turning-arm to hold it from turning until the finger-lever has been again elevated by the impulse of the spring 28, on which occurrence a second turning-arm is released to come in contact with the stop-piece 29 to act in the same manner as the first on the depression of the finger-lever, and so on throughout the series of arms as they are consecutively released. It will be observed that the spring 28 is so placed as to give a quick and vigorous action both to the right and upwardly with an easy touch and that the case is provided with a tongue 1*, partially inclosing the pocket 25, which arrangement serves as a stop for the finger-lever in either vertical or horizontal movement. It will also be seen that the pocket 25 is inclined at its lower edge, so that in case the finger-lever fails to assume its proper position the arm-retaining parts are carried to the right, so that the finger-lever 24 will rise into proper position to engage the tongues 17 of the leaf-turning arms, the inclined edge of the pocket forcing the lever to the right as it descends and putting it into proper position for its elevation by the action of the spring 28.
