MUSIC-LEAF TURNER.

' Application led August 20, 1921, Serial'fNo. 493,960.

To aZZ whom t may concern:

Be 1t known that we,` VALTER S. LUKAW- SKI and MICHAEL A. ZIELINsII, citizens of the United States, residing atChicago, in

the county of Cook and State of Illinois, have invented new and useful Improvements in Music-Leaf Turners7 of which the following is a specification.

This invention relates to music leaf turn# ers and an object of the invention is to pro vide a music stand to permit the turning of the leaves of a boo-k of music or the pages of what is commercially known as sheet. music `without requiring the use of the hands of the user,l permitting' him to turn the music at the proper timel without in any yay interrupting the playing of his instrument. e y

Another object of this invention is to provide a device as specified which can be collapsed and carried about in a relatively small conveniently handled container thereby adapting the music stand for use by bandplayers or analogous musicians when playing` at different places.

A further object of this invention is toV provide leaf or sheet turning means which is operated by means of footlevers, for

Iturning the leaves or sheets of music and.

also to embody balancing means in said turning means to provide even turning of the music and prevent undesirable noises during the operation of the device, and also to provide aA novel structure whereby the height of the sheet carrying head of the rack may be regulated as desired for properly `supporting music sheetsv of different lengths Other objects of the invention will appear in the following detailed description and in the accompanying drawings wherein: W

Fig. l is a front elevation of the improved music stand and leaf turner; Fig. 2 is an enlarged rear elevation of the yhead of the stand showing a portion of the music holding frame or head showing the` turning arms In their normal position. y

Fig.r5 is a View similar to` 'Figi only showing one of the turning arms in a turning position.`

Fig. 6 is' a fragmentary front elevation of a part of the music holding frame or head showing it in its collapsed position.

Fig. 7 is a fragmentary vertical section taken on the line 7 7 ofF ig. l.

Fig. Sfis a cross section taken on the line 8-8 of Fig. l illustrating the mannerv of conlnecting the cover of the music to the rac r.

Fig. 9 is a detail horizontal section on the line 9 9 of Fig. l showing the manner of connecting the arm turning operating pedals tothe standard. Fig.; l0 is a detail section through the stand taken on the line`10-l0 of Fig. l.

Fig. ll is a detail section through a cushioning member embodied in the music leaf turningstructure taken on the line ll--ll of Fig. l. Fig. l2 is a detail view of one of the turning arms. `v

Fig. 13 is a section through the turning arm taken on the line 13-.13 of Fig. 12.

Fig. 14 is a detail section taken on 4the line 1.4 14 of Fig. l2 illustrating the manner of connecting the sheets or leaves of music to the turning arms.

Referring more particularly to the draw ing the improved music leaf turner and stand structurel comprises a standard l vcomposed of telescoping parts 2, 3, and 4 which may be telescoped one within the other to permit the stand to `be collapsedwhen not in use. The lower or base section 3 of the standard l has a brace structure 5 adjustably mounted thereon and held in `position by means of a thumb screw `6 which'eXtends through the sliding collar 7 to, which the brace legs 8 are pivoted. The brace legs 8 are intfurn braced by diagonal braces 9 which are pivoted to the lower end of the standard section 3. The music frame or head structure l0 iscarried at the top of the section 4 and it comprises an upper cross bar 1l and a lower cross bar l2 which are connected at their ends by pivotal connecting bars 13 adapted to fold inwardly towards the axis of the stand lto permit movement of the barl2 towards or from the bar 1l to permit variation of the .space between these bars to accommodate .sheets of music of different lengths. The bars 1l and l2 are preferably formed of .angle material as clearly shown in Fig. 8 of the ldrawings and the bar 11 has spring clips 14 connected thereto adjacent its ends which are adapted to engage the backs of music books or the cover and back sheets of sheet music and clamp them securely against the upper cross bar 1'1. The upper cross bar 11 has a downwardly extending bar 15 attached thereto which carries a socket 16 on its rear surface to which the upper section 4 of the standard 1 is connected. The bar 15 is positioned intermediate the ends of the bars 11 and 12 and the latter bar is slotted as shown at k17 to permit the bar 15 to extend therethrough which permits the angle bar 12 to slide up and down vupon the bar 15 to permit reguylation Vof the distance between the bars 11 and 12. The lower bar 12 has an extension'18 formed thereon to which a spring clip structure 19: is pivotally connected as shown at 20. The spring clip structure 19 may be of any approved form preferably comprising a substantially vcylindrical spring member 20 which engages the gripping and operating members 21 forcing their gripping ends 22 into binding engagement with the bar 15 to hold the bottoni bar 12 in adjusted positions upon the bar 15. lt will be seen from the foregoing description and Fig.7 of the drawings that an operator may easily and quickly adjust the position of the bai' 12 relative to the bar 11 by releasing the clip structure 19 and when the clip structure is released the bar 12 will be securely held in 'adjusted positions. If it is so desired it is to be understood that the gripping A ends 22 of the members 21 may have felt or analogous material attached thereto to provide firm and nonslipping engagement with the bar 15 withoutv departing from the spirit of this invention.

v Leaf turning arms 25 are provided which are pivotally connected as shown at 26 to an extension 27 on the bar 11 and they are provided for turning sheets of music when necessary ywithout requiring theV use of the Each of the arms provided :with a segmental gear 29 which meshes with rack teeth 30 on a sliding bar By -particular reference to Figures 4 and 5 of the drawings it will be noted that the rack teeth 30 are arranged in sets 32,

the number of these sets corresponding tol the number of turning arms 25. Owing to the factthat the arms 25 are disposed one against the other, it is necessary to position respective'sets 32 Von the raclr teeth 30 in laterally spaced relation and if it is so deL sired to simplify and expedite manufacture, the bar 31 may be composed'of a plurality of bars 33 as clearly shown in Fig. 6 of the drawings connected for synchronous movement by means of rivets 34 which also extend through a suitableslot 35 formed in the substantially horizontal side ofthe bar 11.k The outermost of the bars 33 has an .angle extension 36 formed thereon to which a link 37 is pivotally connected.' The linh thereto, the downward movement of which is limited by ears 42 cut from the lever 38 and bent `into the path of the arms 40 and 41. The arms 40 and 41 have connection, by means of wires, cords or analogous flexible members 43, to a bar 44 which is pivotally mounted, intermediate its ends as shown at 45, upon the bai' 15 preferably by means of the rivet or pivot 45 which is attached to the socket 16. The bar 44 is connected, Vby means of chains, wires, or analogous flexible devices 48, to footpedals 49 and 50 respec-l tively, one of which is connectedto the bar 44 upon one side of its pivot while the other is connected to the bar upon the opposite side of its pivot as clearly shown in the drawings, for rocking the bar in oppositeV folded upwardly along the standard section 3 when it is desired to collapse the music stand and turner structure.

rlhe wires or flexible members 48 have shock absorbers or cushioning members 54 interposed in their lengths which are provided, in combination with the bar 44 to absorb abrupt action which might be trans-- mitted by the foot pedals to the operation and to insure even steady operation of the turning arms 25 so as to eliminate undesirable noises. Suitable cushions 55" are provided, which are carried by the bar 11, to cushion the movement of the arms'and prevent noises during their operation.V Shockabsorber structures -54 are comparatively simple in construction comprising body shells 56 which are connected to the downwardly extending portions of thewwires -48 and which slidably receive therein piston rods 57 which are connected to the upwardly extending lengths of the wires 48. y The rods 57 have heads 58 upon their inner ends against which cushion springs 59 engage. The cushion springs 59 also engage` against an adjustable nut or head 60 which is adjustably carried by the body shells 56 and provides for regulating the tension of the spring 59..

The turning arms 25 are particularly constructed so as to readilyv adapt them for movements to facilitate the attaching of Sheets of music thereto, that is, each of the arms 25 is formed of a pair of sections 62 and 63 pivotally connected as shown at 64. The section 62 carries a stop pin 65 which is engaged by a projection 66 on the section 63 to limit the upward pivotal movement of the section 63 and by the end of the section 63 to limit the downward pivotal movement of the latter. The section 63 has an enlarged head 67 on its free end to which a flat spring 68 is attached. The fiat spring 68 has a plate 69 of any suitable material, attached thereto to the inner surface of which a sheet 70 of felt or analogous material is attached for gripping a sheet of music and clamping it between the facing surfaces of the felt 70 and hea-d 67, the spring 68 acting to urge the felt 70 in engagement with the head 67. In attaching a sheet of music to one of the turning arms 25 the music is properly placed upon the music frame or head structure l0 and the section 63 is swung upwardly after which the Spring 68 is moved outwardly to space the felt 70 from the head 67 and the section 63 is then moved to its normal position in alignment with the section 62 with the sheet of music to be turned gripped between lthe felt 7 O and head 67 after which the spring 68 is released and the felt 70 is forced between the spring into firm clamping engagement with the sheet ofmusic.

From the foregoing description taken in connection with the laccompanying drawing it will be apparent that a combined music leaf turner and stand has been provided which is relatively simple in construction, one which will be efficient in its operation and may be operated by a musician with his foot to turn the sheets of music as necessary, without in any way interfering with 54 and bar 44.

It is, of course, to be understood that the invention may be construct-ed in various other manners and the parts associated in different relations and, therefore, we do not desire to be limited in any manner except as set forth in the claim hereunto appended.

Having thus described our invention what we claim is:

In a device of the character described, a rack including'upper and lower cross bars, a central bar having its upper end connected to the upper cross bar and means carried thereby whereby the lower cross bar is adjustably mounted thereon, said means comprising an extension formed on the lower cross bar having an opening through which the central bar extends, a spring clip having pivotal connection with theextension, said spring clip including a substantially cylindrical spring member engaging the arms of the clip, gripping ends adjacent the spring member adapted to normally grip, the central bar and gripping and operating members extending divergently from the gripping ends whereby to manipulate the gripping ends for adjusting the lower cross bar on the central bar.

In testimony whereof we aiiix our signatures.
