HENRY GUTH, OF PEOBIA, ILLINOIS.

MUSIC-TURNER.

To all whom it may concern:

Be it known that I, HENRY GUTH, citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Music-Turners and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to a music rack and it has for one of its objects to provide means for turning the leaves of music held thereon.

It has also for one of its objects to turn the music in either direction with equal facility.

An object also is to provide a music leaf turner which may be readily operated by the foot of the performer and without the use of the hands.

Another object is to simplify devices of this kind.

A still further object is to provide a member for holding the music leaf which will not.

injure the leaf in any way.

In the appended drawings Figure 1 is a rear elevation of the music rack mounted upon a stand. Fig. 2 is a side elevation of the entire music rack and stand shown on a much smaller scale. Fig. 3 is a perspective view of a portion of the rack illustrated in Fig. 1 showing a slide. Fig. 4 is a top view of a portion of the rack and slide shown in Fig. 3. Fig. 5 is a longitudinal section of part of the rack and slide. Fig. 6 is a transverse section of a portion of the music rack and slide shown in the foregoing figures. Fig. 7 is a longitudinal section of a portion of the music rack and the slide and an arm for turning the music. Fig. 8 is a similar view with the music turning arm in a different po sition.

Serial No. 369,044.

the top of the rack is a horizontal bar D having a recess E, which, as shown in Fig. 3, has parallel overhanging portions F to constitute a dove-tailed guide.

At G is a slide which, as shown in Fig. 6, is of such a form as to snugly fit the recess E and slide therein without binding and without leaving its seat, being entered and withdrawn endwise therefrom when desired. Near the upper edge of the slide adjacent to one of the overhanging portions F is a series of ratchet teeth clearly shown at H in Fig. 3, all facing in one direction. Near the bottom edge of the slide is a corresponding series of teeth J placed directly opposite the teeth H but facing in the opposite direction. Upon the middle vertical bar of the rack A is a bellcrank lever K pivoted upon a stud L as shown in Fig. 1. The upper end of said lever extends upward to the teeth J with which it engages, the opposite end of the lever having attached thereto in any good manner the end of a rod M divided into sections whereby it may be made in compact form forthe purposes already stated. Above the stud L is a second stud N which carries a similar lever 0 whose upper end is adapted to engage the up per set of teeth H of the slide G, its other end having attached thereto a rod P corresponding to the rod M just described and divided into sections in the same manner. In order to make the device compact the lever K has a slot at Q arranged concentric to the fulcrum of said lever. Through this slot extends the stud N just mentioned which supports the lever 0. By this means the lever K can be rocked on its pivot or fulcrum .the slot permitting such action. Suitably secured to the vertical portion of the frame A on which the levers are pivoted are two springs R each of which bears against one of the levers O K for normally holding them in position for action.

Pivoted to one of the legs of the stand are two foot levers or pedals S to which the rods M P are attached. Upon the upper portion D of the rack adjacent to the teeth H of the slide G are two lugs or stops T U. The lever 0 due to its spring R finds a resting place against the lug U and in the operation of turning a page of the music, by the pressure of the foot upon one of the foot pedals S, the lever O is shifted from that position toward the left as viewed in Fig. 1 until it strikes the stop T which limits its movement in that direction. In making this movement the lever engages one of the teeth H of the slide moving it to the left a distance sufficient to turn the leaf, but this will be described later. U on releasing the foot edal S the lever O wi l again reach its position against the stop U. On the lower edge of the member D are two similar lugs VWV the former having the lever K normally resting thereagainst, the latter limiting the movement of the lever, due to the foot, in the same manner as described with regard to the lever O, the move ment of the said lever K shifting the slide in the opposite direction. In Fig. 3 and also in Fig. 4 the stop U is shown provided with an inclined portion U against which the lever K bears, and in the latter figure it will be observed that the lever which is shown in cross section rests upon the highest portion of the incline U and outside of the line of the points of the teeth II the line of these points being shown by the broken line. The lug V adj acent to the teeth J is also provided with, an inclined portion V by which, in the same manner, the lever O shown also in cross section, is also held outside the line of the points of the said teeth J.

A certain amount of flexibility resides in the levers K O so that when moved on their fulcrums they will be carried down the inthe center.

cline into engagement with the teeth of the slide G. In Figs. 4 and 5 the positions of the levers are indicated in broken lines showing them in engagement with the teeth. The purpose of the incline is that when one of the levers has shifted the slide Git will be carried out of the way of the teeth so that the slide will not be interrupted in its movement in the opposite direction when the other lever is operated. It is obvious that in the position shown in Figs. 4 and 5 the slide may be shifted in either direction without hindrance from either lever.

In Fig. 1 there is indicated in broken lines, an opening or window 2 in the front surface of the member D this being shown in Figs. 6, 7, 8 and 9. Above and below this opening are lugs 3 and 4 respectively, carrying a shaft 5 whichlies parallel to the face of the rack at Mounted on said shaft is a series of members 6 by each of which is carried an arm 7 (Fig. 2) each carrying on its free end a music-leaf clip 8 shown also in Fig. 12. The rear ends of these members 6 are provided with tri-angular notches as shown in Figs. 7, 8 and 9.

In Figs. 6 and 11 the front surface of the slide G is shown, being provided with a series of longitudinal grooves 9 corresponding in number to the number of the members 6 just described. The width of the said members 6 and the position of the pivot or shaft 5 which carries them, is such, with relation to the face of the slide G that one edge of the said members 6 lies normally within the grooves 9, this being clearly shown in Figs. 6 and 7.. In the bottom of each groove 9 is a slot 10, these 'slots being arranged at regular intervals throughout the length of the slide.

One of these is shown in Figs. 7, 8 and 9.

Positioned near the front face of the slide in each groove is a pin 11, Fig. 10, each of which is directly opposite one of the slots 10. In Fig. 7 the member 6 is indicated in its position of rest with the pin 11 in position to engage it. By a movement of the slide through one of the levers the slide G is shifted toward the right, and said pin 11 contacts with the said member 6 and moves it on its pivot. As this occurs the opening 10 which has approached and is behind the member, permits the projections of the said member to swing thereinto. As the movement continues farther the said member 6 is carried by the pin to a position at right angles to the length of the slide as shown in Fig. 8. A still farther movement carries the pin beyond the member 6, as shown in Fig. 9, at which time the end of the slot 10 meets the member and swings it out of the slot 10, and a still farther movement causes the member to seat in the groove 9 as shown by broken lines in said Fig. 9, said member 6 being now in the position opposite from that shown in Fig. 7. During this movement a leaf of music has been turned. A single movement of either lever imparts to the music carrying arm a full semi-circular sweep, the springs It returning the levers to their normal position ready for a succeeding movement. The members 6 by being seated in the grooves 9 and extending beyond their pivot in both directions are locked in place in the position shown in Fig. 7 or in broken lin s in Fig. 9, so that they cannot be moved except in a positive manner by the pins 11 as'they are brought into contact with them.

My music rack will accommodate music of any number of pages it being only necessary to provide extra arms 6 upon the shaft 5 and corresponding grooves in the slide G as well as additional ratchet teeth on the latter.

I now desire to draw attention to the form of the clip 8 shown in Fig. 12 for holding the music leaf. This consists of a plate of light spring metal, preferably brass, having downwardly extending tongues formed by cutting parallel vertical slits 13 connected by horizontal-slits 14 at their lower ends. The upper ends of the slits 13 communicate with horizontal slits 15 and with the ends of these communicate vertical slits 16 described. The slits 16 lying between the pairs of slits 13 provide for ready yielding of the tongues 12 while the upper extremities 17 of said tongues, which are created by the slits 13 and 16, also yield. Tongues 18 are created between the slits 13 and 16 which also freely yield. A music leaf inserted beneath the tongues 12 substantially in the manner shown and partially torn' away and indicated by 19, is held with sufiicient friction to retain it in position and the tongues 17 and 18 yield in opposite directions so that the paper will not be cut or broken or even creased. If the clip were destitute of the tongues 17 and 18 the paper would be bent abruptly at the slits 13 and cause it to readily break and tear, but the small tongues in yielding in opposite directions prevent this while allowing the leaf to lie perfectly smooth and without cockling.

In presenting my invention it is not my desire to be limited to the exact form or construction of the parts nor the particular assembling of the same.
