music TURNER AND CARRIER.

Specification of Letters Patent.

Patented Nov. 22,1921.

Application filed January 31, 1920. Serial No.- 355,306.

' so that the same may be transported or carried from place to place, together with such additional music as it may be desired to play,

and to turn the same successively in the playing, reverse the same or return all of the sheets to an initial position so as to accommodate for repeats or replaying.

A further object of the invention is to provide a device of the character specified which can be just as conveniently moved from one piano to another as a song book or folder,

7 in addition to being a relatively desirable and perfect form of carrier or folio; which can be applied to a Il'lllSlC stand as well as to a piamo, and which includes novel means for actuating a series of arms independently to turn thepages or sheets as the notes are played and each sheet is completed to permit said turning arms to be reversed at will and to permit all of them to be turned back after the playing is completed, such mechanism being capable of convenient control by a hand or foot without inconveniencing the playingaction and including a motoror actuating means of novel construction and simple in design, whereby the device is capable of being economicallyproduced and sold.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combine-j. tion and arrangement of parts and in'the details of construction hereinafter described and claimed, it being understood that within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings:

Fig. 2 is an enlarged vertical sectional view taken on the line'2-2 of Fig. 1, but wlth the carrier or folio part omitted;

Flg '3 is a detailed fragmentary perspective view of the operating chair and one of the turning arms, the same being shown in disassembled relation;

Fig. 4: is a side elevation of the device applied to a stand;

Fig. 5 is a plan View of the actuating means or motor;

Fig. 6 is a vertical sectional view thereof; 7

and

Fig. 7 is'a sectional elevation of the device looking toward one side. Referring to the drawings in detail, my improved music turner and carrier embodies a carrler proper 10 which is in the form of a folio or folder having the back portions 11 and 12 provided with the intermediate or binding portion 13Vmuch in the same mannor as an ordinary folio or book. The device is covered with leather, leather imitation or the like over stiff backings, which backings are provided with cooperating handles M for convenience in transporting or carrying the device from place to place. A fastening strap l5-is also provided on one backing to engage -its cooperating snap fastener or socket member with a snap or ball member 16 carried by the other, although it is to be understood that any other suitable fastening means passing over the free edges and connectingthe backings' may be employed. In this manner, the carrier or folio may be opened so as to rest upon the ledge of a piano music support or panel in convenient position for use.

Each of the backings is provided with a suitable covering of leather or cloth at the inside as designated at 17 and each is formed with a pocket 18 between the inside lining and the outside cover or backings for acconi modating additional music as clearly indi nearly at the top or slightly spaced from the top edge of the folder and suitably secured in position. This tube rotatably receives spindle 20, the upper end of which. is of circular cross section and provided with a transverse key or pin 21 above the upper end of the tube or tubular casing. A series of turning arms 22 horizontally disposed are provided with leafengaging clips 23 ant 1 spindle and arms are exposed, the remain said arms are provided at their inner ends with sleeves 24ihaving'internal' 'rooves orkey. slots 25 preferably terminating. at spaced points from the upper andlower edges or ends thereofforreceiving the pin or. key 2l during the turning action, while the intermediate recesses 26 accommodate said pin between motions." The'upper arm has its sleeve or hub in alinement therewith and the sleeves therebeneath' are successively offset downwardly at diii'erent degrees or lengths as indicated at 27 so that the sleeves are accommodated on the projecting upper end of the spindle to turn freely thereon except 7 when engaged by thekey or-pin 21 At its intermediate portion, the "spindle 20; is provided with a spiral groove or worm thread 28 the spindle bein enlar ed at this portion if desired andthe tubular housing '19 having an opening 29 disposed through 'itswall axially of a. latch casing 30 projectinggfromthe housing. A latch or pin 31 is mounted in the casing and has a finger hold 32 by which it may be disengaged at its inner end from the groove, it being understoodthatsaid pin opposite its headedend engages the spiral groove 28, after passing through-the opening-29. The pin is held in an engaged position in the manner of a spring pressedibolt or catch and for this purpose is provided with a-nenlargement33 within the casing, between which andthe outer end of the casingiso, as to encircle the piI1,. is disposed an expansible helical, spring 34; so as to hold'the pin normally in an engaged position by pressure against said enlargement or collar 33. By this means, the spindle may be caused to elevate as it turns or by withdrawing the pin, the spindle may be allowedto drop,.so that the key 21 will be disposed in the grooves ofthe lowermost sleeve or hub 24L whereby-the sleeves may be successively turned or swung to the left to turn the music sheets as the spindle is intermittently I'D-1: tated and the means above described causes its elevation and successively brings the key. into engagement with the grooves of the.

insideforming shoulders 51Ifacing in sleevessucces'sively one above the other. 'It will be also understood as the key passes into the recesses, the sleeves will'be released until the next groove is engaged toturn the suc ceeding arm as desired. When all of the arms'havebeen turned and consequently the sheets, they may be turned back by means of an upright arm 35 carried by a said springs from unwinding, the gears ring 36 from which it projects upwardly. the ring having a finger piece 37. by which it may be turnedin a groove in the housing 19. It willalso be understood that the arms may be independently turned or swung backwardly for repeating or the like.

.As shown particularly in Fig. l of the drawings, the upper portion of the housing,

ing portion being covered by the lining 17. The upper portion. of the spindle is of round or circular cross section as before stated, andthe lowerportion is of polygonal or square cross section as 'indicatedat 38 so as to be connected to the actuating device or motor which includes acasing 39 in which is rotatably mounted V crown wheels mesh with the opposedin wardly' extending teeth of the crownv gears iO avhich are mounted to turn in the casing on stub shafts or p1vots43 which are fixed to thecasi'ng. Connecting the shafts or, p vots 43 and the crown gears arespiral springs 144: like clock springs, the ends thereof being-connected to the pivots'and to the gears res ectively slidablyfengaged' beveled pinion or m1tergear/i2-d sposed tosoas to operate the pinion 42 andthe shaft thereto. V In order-to wind the springs, the casing is provided with a depending extension ao;

in mesh with peripheralteeth' disposition at diametrically opposite reverse directions.

'20 in opposite directions when conne cted 48 on the wheels or gears 40,1'which owing to their sides of the pinion 42,serve to drive the latter in "The shaft 46 isprovided with lzey s9 and by pushing? the shaft in, V r V the pinion will engage the teeth I lSsofJthe rear gear so so that thespring thereof may be wound. By pulling the'shaftjout through the mediumof the key, the frontlgear spring maybe wound, and by disposingrthepin on 57 at intermediate position,

provided with ratchetextensions 50at the to be engaged'by a catch or pawl 52 passing through the casingat one side. and pivoted intermediately of its ends on a vertical pivot 53 in a lateral extension 54: formed on or attached to the casing. At 7 v 7 either, gear 40. Wlll be. free to turn. In orderctopre' are.

L the direction in which the gears turn adapted eitherside of the plvot, the pawl is provided with push buttons 55 and 56 so that the pawl may be released from the position shown in Fig. 7 underlying the shoulders of both ratchet sleeves or extensions 50, wholly beneath one shoulder so that the other shoulder will be released in order that the corresponding gear may act under its spring to turn the pinions 42 and the spindle or shaft 20.

It will be seen that the shank portions of the buttons project through the lining 17 as well as the key 49 and in the operation of the device, the arms are disposed at the right hand side and engaged with the music sheets, except that the arm 35 will be disposed at the left. The spindle 20 will be in its lowermost position and with the springs properly wound and held from'unwinding, the button 55 is depressed or repressed inwardly to rock the pawl 52 on its pivot 53 whereby the inner end of the pawl operating through the slot 57 in the casing at one side, will be disengaged from the shoulder 51 of the rear gear and into en gagement with the shoulder of the front gear, thus holding the latter as before and releasing the former so as to turn the pinion 12 and the spindle in a clockwise direction or to swing the arms22 successively to the left as released to correspondingly turn the sheets. By pressing the button 56, the pawl will be moved in the opposite direction to release the front gear and permit the other spring to act to return the arms to the right hand side, the rear gear being held against turning by engagement of the pawl beneath the corresponding shoulder 51, a seriesof which are provided corresponding to the spaced series of teeth on the gears 48. In this manner the arms may be independently returned for repeating, and it will also be seen that when the pinion 42 is disposed between smooth or mutilated portions of the gears or crown wheels .48, the spindle 20 may be freely turned by the upright arm 35 to return all of the arms and sheets to closed positions. The key 4:9 and the buttons 55 and 56 are conveniently located so as to be readily manipulated by the player and it will be seen that the buttons can be operated without interference to the playing. 6

In Fig. tof the drawings the device is shown applied to a music stand 58, preferably of the foldable type having the legs 59 and the rest 60 to the ledge of which is secured an arm 61 having pivoted thereto a plurality of hell crank levers 62, one for each button and connected by rods 63 to foot pedals 6e pivoted to the legs so that the buttons may be manipulated by the feet. Thus itwill be seen that I have provided a simple and relatively inexpensive device for inclosing music folders or books and for supporting the same in position to be turned and turning them as desired, whether applied to a piano or music stand adapted for use in playing string instruments, although it is to be understood that the device may be applied equally as well for turning sheets or pages other than music sheets, as for instance, for exhibition purposes or the like.
