ROTARY MUSIC HOLDER Filed Aug. 27, 1947 INVENTOR. Warren Hedenlm a as BYO'ZJJFH'LL ATTOQA/EYS Patented Aug. 8, 1950 ROTARY MUSICHBLDE-B? r e Frederick n ,4R sel;le Par Appl cationuxuigust 1941, se i l ND; 77055 Y This. invention relates to musict'holdersxand moreiparticularly. to rotarymusic holders adapted:

forzatta'chment .to. somemanually: held "musical instruments.

The need for facilitating the turning of music While engaged in the operation of some manual-1y held musical instruments-has -long been felt.

It is an object of the instantinventionito provide' a music "holder capable of being rotated -so that the music on either side of the sheet is quickly available.

A further object is to provide a compact light weight device the operation of which is both simple and positive.

Other objects of the instant invention will become apparent in the course of the following specification.

In the attainment of these objectives, the rotary music holder is formed at the top of opposing clamp members under closing tension adapted for insertion of the music. The opposing clamp members are attached at the top of a downwardly turned rotatable support the base of which is designed for insertion in the usual co-acting aperture provided or which may be provided for mounting music holders on musical instruments of the type described. The downwardly turned rotatable support comprises a top and bottom member with the top of the bottom member rotatably inserted in the base of the top member. A slot substantially at the base of the top member is so formed that the rotation of the opposing clamp members is limited to the amount of rotation within the requirements of the performer. Furthermore, the mechanism is so devised that only a partial manual movement of the opposing clamp members is necessary for a rotation through a straight angle. This is accomplished by inserting a spring within the top member of the downwardly turned support adapted to press against the top of the bottom member rotatably inserted therein. The arrangement devised insures rapid and positive rotation when desired and prevents undesirable rotation.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings showing by way of example preferred embodiments of the inventive idea.

In the drawings:

Figure 1 shows a front elevational view of the rotary music holder constructed in accordance with the principles of this invention.

Figure 2 is a sectional view through the line 2--Z of Figure 1,

Figure: 4 is' a fragmentary-view of the down--- wardly turnedsuppor t for the musieholder show ing the rotation mechanism-enlarged.-

Referring now in greater detailto the drawingsc which like reference numerals indicate like parts; reference "numeral I10: indicatesdslie rctary music' holder, :I the clamp;- IZ' t e ters member of the downwardly turned support, I3 the bottom member of the downwardly turned support, and I4 the revolving mechanism.

The clamp II is formed of the two opposing clamp members I5 and I6 formed integral with and substantially perpendicular to the base members I'I adapted for insertion of the music therebetween. By bringing the opposing clamp members I5 and I6 substantially to points at the top minimum interference with the music is encountered.

At the base of the opposing clamp members I5 and IS, the spring member I8 is turned upwardly along each of the longitudinal edges with the slot I9a therebetween in order to provide means for insertion of the opposing clamp members I5 and I6 of the clamp II therebetween.

At either side of the spring member I8, the slits I9 are formed for insertion therethrough of the handle members 20 formed integral with and in the plane of the opposing clamp members I5 and 6. By pressing the handle members 20 together with the fingers, the opposing clamp members I5 and I6 are moved apart against the closing tension of the spring member I8.

' The horizontal member 2| with upturned edges adapted to be superimposed on the spring member I8 has cut out portions 22 (Fig. l) for insertion against the inside surface portions of the handle members 20 thereby providing substantial support for said opposing clamp members I5 and I6. The spring member I8 and horizontal member 2| are removably attached to the top of the subsequently described top member I2 of the downwardly turned support.

The top member I2 is a partially hollow tube with inside tap 23 at the top adapted for insertion of the screw 24 through aligned apertures in the spring member I8 and the horizontal member 2|.

Near the top of the top member I2, on the inside, is the coil spring 25 adapted to be compressed therein by the top of the subsequently described bottom member I3.

The bottom member I3 of the downwardly turned support is adapted to be inserted in the bottom of the top support l2 at one end and at the opposite end in a co-acting attaching means on the musical instrument (not shown).

Substantially at the base of the top member I3 is the slot 26 curved upwardly and downwardly, over substantially 180. The pin 21 inserted into the top of the bottom member [3 under tension of the coil spring 25 permits the top support l2 to be rotated only through some 180. The pressure of the coil spring 25 on the top of the bottom member I3 forces the pin 21 against the lower periphery of the slot 26 obviating any movement of the rotary music holder except under a substantial force that must actuate it at least upwardly to the maximum point of elevation whereupon the coil spring 25 will in general finish the operation of rotation.

It is apparent the specific illustrations shown above have been given by way of illustration and therein extending from its lower end to a point intermediate the ends thereof, said top member having a transverse slot formed therein adjacent said lower end, a bottom member therein adjacent said lower end, the ends of said slot being substantially apart, said slot being curved upwardly intermediate its ends, a bottom member having its upper portion in said bore and rotatable therein, a pin adjacent the upper end of said bottom member and extending through said slot, and resilient means in said bore urging said bottom member downwardly.
