MUSIC STAND.

Application filed April 13, 1925. Serial No. 22,922.

This invention relates to improvements in devices for suppoting music being played, and especially to stands such as are used by musicians in orchestras, bands and similar organizations.

Written music is now almost entirely in the form of books or leafiets,which rest on the standand must be turned by hand. The musician must therefore remove one hand from his instrument in order to turn the page, which is frequently, necessary at a poor moment destroying, momentarily the continuity of his playing. In the case of a leaflet the same is liable to slip or blow off the stand'and the page of a book frequently refuses to stay turned. Such happenings, which very often occu: make for confusion and lack of proper harmonious rendering of the piece being played.

The principal object of my invention therefore is to eliminate the above deficiencies in the necessary moving of the music by arranging the music in roll instead of sheet or book form, and providing a stand in which the roll is removably mounted with means for enabling said roll to be turned to expose an unplayed portion by the footof the musician. The player is therefore able to retain the use of both hands in manipulating his instrument. Further the possibility of themusic falling off the stand or being otherwise moved out of place is also eliminated.

The control means is so arranged that it does not interfere with he desired adjustgularly, as is necessary to suit the needs of different users.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

33. 1 is a perspective view of the stand readiness for use.

Fig. 9- is asectional end view of the roll holding box taken on a plane mainly just inside one of the ends thereof.

Fig. 4L- is a sectional plan on the line let of Fig. 2. a

Fig. 5 is a fragmentary vertical section on the line 55 of Fig. 2. i I

Fig. 6 is a fragmentary side view partly in section of the lower end of the stand pedestal showing the pedal structure.

7 is a fragmentary vertical section on the line 7'l' of Fig. l.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes a tubular pedestal supported by suitable outwardly projecting legs 2, mounted in a manner common to such stands. Slidable and turnable in the pedestal is a tubular stem 3'held in any desired position by a thumb screw L, as shown in Fig. 1. The upper end of the stem 3 is pivotally secured to brackets 5 by horizontal clamping bolts 6, the brackets being mounted on the back of a rectangular casing 7 which is open in front.

Removably mounted in the casing at the top and bottom and adjacent the front there of are spools ,8 and 9 respectively, these spools being about the size and general form of those used in connection with player piano rolls. The lower spool 9 is mounted on spindles 10 and 11. The spindle 10 is longitudinally immovable in the casing and its inner end is square or otherwise shaped to engage the spool in removable driving tion, so that when the spindle is turned the spool will turn also. To enable the spindle to be turned its end outwardly of the casing is provided with. a suitable button or handle 12. p

The other spindle 11 is mounted in con-- nection with a spring 18 on the outside of the casing which acts to hold the inner end of the spindle seated in the adjacent end of the spool. The spindle 11 h asa handle 14 onits outer end so that it may be drawn clear of the spool, as shown in dotted lines in Fi 5, thus ermitting the spool to be also dis engaged from the spindle 10 and removed from the casing-3 The upper spool 8 is also mounted on two spindles 15 and 16 corresponding in function to the spindles 10 and 11. The spindle 16 is identical in form, mounting and operation as the spindle 11, having a spring 13 of the same form. The spindle 15 however is of special construction and arrangement, as will be hereinafter seen. a

The spindle 15 has a pinion 17 mounted in driving relation therewith, which pinion meshes with agear 18 turnably mounted on a fixed shaft 19 which in turn is mounted in the casing behind the spool 8. Turnable 011 the shaft 19 in spaced relation thereto is a sleeve 20. 11 coil spring 21 is disposed about the shaft between the same and the sleeve, one end of said spring being fixed to the sleeve and the other end to the shaft. The latter being immovable, the spring of course tends to rotate the sleeve when the spring is wound up.

Mounted in connection with the sleeve is a spring pressed dog 22 normally engaging a ratchet wheel 23 which is fixed onto the gear 18.

rapped around the sleeve for a certain number of turns centrally of the length thereof is a flexible cord or wire 25 which then projects down past a direction changing roll 26 in the casing, over a guide and direction changing sheave 27 mounted adjacent the pivots 6, down through the stem and pedestal 1, around a guide sheave 28 at the bottom of said pedestal, and then upwardly to a connection with the inner end of a pedestal arm 29. This arm has a foot pad 30 on its outer end and is mounted on a cross bar 31 extending between two of the legs 2. The inner end of the arm 29 moves in a vertical and curved guide 32 fixed on the pedestal. In order to be able to limit the upward movement of the pedestal arm if desired the sides of the guide iave vertically spaced holes 33, through which a cross pin may be placed. The downward movement of the arm is limited by a fixed stop of suitable character.

Themusic used in connection with my stand is in the form of a continuous roll 35 normally wound on the lower spool 9 and adapted to be unwound thereform onto the take-up spool 8. The latter has suitable means for attaching the end of the roll thereto, such for instance as is commonly employed in connection with player piano rolls and the like.

The parts of the operating mechanism are so arranged that'when the pedestal is depressed the wire 25 will be unwound from latter through the pinion 17 will cause the the sleeve 20 which rotates the same. The sprlng 21 will become wound up, the dog will rotate the ratchet and gear and the rotation of the spool 8 in adirection such that the music roll 35 extending'between the spools will move upwardly. Also the relative proportion of the parts is such that a complete depression of the pedal causes the music roll to move the entire distance between the spools, though this can of course be varied by varying the amount the pedal is moving;

lVhen the pressure is removed from the pedal the spring 21 tends to unwind, causing the rotation of the sleeve 20, the winding of the wire 25 thereon, and restoring the pedal to its original position. At the same time no rotation of the spool 8 takes place since the dog 22 then backs around the ratchet 23 without turning the same and of course without turning the gear which controls the turning of the pinion 17.

Vhen it is desired to rewind the music on the spool 9 said spol is turned by turning the handle 12. At such time it is of course not desired to have the sleeve 20 turn so some means must be provided to prevent this without interfering with the necessary backward rotation of the spool 8.

If the dog 22 was raised from the ratchet wheel this of course would serve the purpose but this dog is practically concealed, is hard to get at and does not occupy any fixed location relative to the casing. It cannot therefore be provided with releasable means operable from outside the casing;

I have therefore arranged for the driving connection of the pinion 17 with the spool 8 to be broken when deisred, so that the spool may rotate backwards, enabling the music roll to be wound on the spool 9 without turning the gearing or the sleeve 20.

The spindle 15 and associated-parts are therefore constructed as follows:

Adjacent but spaced from its inner end he spindle 15 has a short rectangular portion 1. adapted to lit a correspondingly shaped socket in the end of the spool S. The round portion of said spindle at the inner end thereof beyond the portion 15 is longer than the latter and fits a round socket in the spool. The spindle 15 is slidable in its bearing 36 and is provided on its outer end with a handle 15;

The pinion 17 is feather-keyed onto the spindle so that the latter can move'longitudinally without moving the pinion. It will therefore be seen that if the spindle 15 is drawnout the portion 15 thereof may be removed from its socket in the spool without entirely withdrawing the portion of the spindle beyond the part 15 from said spool. The spindle may therefore freely turn and at the same time is maintained supported at both ends.

The pinion and spool are held from longitudinal movement, and the spindle 15 limited in its outward movement by a brack et 37 mounted on the casing. This bracket projects between the spool and pin without interfering with the necessary outward. movement of the portion 15 of the spindle.

All these features are fully shown in Fig. 7.

If it is desired to rotate the spool 8 by hand in the same direction as that imparted thereto by depression of the pedal, this can of course be done by turning the handle 15 without pulling the spindle 15 out, since with such operation the ratchet 23 will move ahead of the dog without imparting movement to the sleeve 20. A swivelled stop or latch 88 is placed to normally engage handle 15 and prevent outward movement of spindle 15.

The casing may be swiveled on its pivot 6 to set the same at different angles without interfering with the operation of the wire or causing the same to bind, owing to the guide sheave 27 being located adjacent the pivots 6.

Also vertical adjustment of the stem can be had without necessitating any adjustment to the wire being made, since the spring 21 is of ample extent to wind or unwind, to take up or let out the wire the necessary amount from the sleeve 20 without interfering with the further operation of the'spring when the pedal is depressed.

The end cuts or sockets in both spools 8 and 9 are preferably of the same form, so that the spools can be interchanged if desired.

I may also associate a dog and ratchet mechanism 39 with handle 12 if desired, so as to enable the music roll to be maintained taut between the spools.

The device may also be installed, with certain necessary rearrangement of parts, on pianos and organs.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

lVhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:
