' MUSIC STAND AND LEAF TURNER Filed May 4, 1929 BY r W ATTORNEYS Patented Feb. 23, 1932 PATENT OFFICE ROBERT ROBSON, OF BAYTOWN, TEXAS MUSIC STAN D AND LEAF TURNER Application filed May 4,

This invention relates to music holders, and more particularly, to operating mechanism for mechanical music turners, for use in orchestras and the like.

In my prior Patent No. 1,705,416, I have shown a mechanical music leaf turner applied more particularly to a piano, with a multiple pedal operating mechanism.

The present invention is an improvement and simplification of the operating mechanism for devices of this character by means of which one foot pedal is utilized to successively operate the multiple lever operating devices.

One sheet of drawings accompanies this specification as part thereof, in which like reference characters indicate like parts throughout.

Music rack 1 provided with a plurality of telescope shafts 2, of different lengths, each of the shafts 2 carrying pulleys 3 to which are secured music leaf arms 4, are provided sub-- stantially similar in detail with the structure shown in my prior Patent No. 1,705,416. To each of the pulleys 3 is secured a cord 5, by

2 means of which the pulleys 3 may be rotated to swing the music leaf arms 4 from the right hand side of the music shelf to the left hand side to turn the sheets of music. Spiral springs 4 are associated with each music sheet arm 4 so that each arm will be returned to the right hand side of the music shelf when tension is removed from its cord 5.

As illustrated herein, the music shelf 1 is mounted upon an orchestral stand by means 85 of a bracket 7 secured to a tubular pedestal 8,

which, in turn, is supported by a housing 10 supported by legs 9.

At the top of the tubular support 8 is mounted a plurality of pulleys 6, over which cords 5 pass and extend downwardly to the tubular support 8 into housing 10.

Housing 10 is adapted to contain a plurality of weights 13, 14, and 15, placed side by side, to which are secured the ends of the cords 5. On one face of each of the weights is provided a rack 16.

The weight 13, on the extreme left hand side, is provided with a trip 21, adapted to operate by contact a pawl 21 mounted on the front wall of housing 10. This pawl is adapt- Serial No. 360,545.

ed to normally engage the rack of weight 14 next adjacent on the right to weight 13. Similarly, the weight 14 carries the'trip 22', adapted to operate in the same manner, a pawl 22 similarly mounted and adapted to engage the rack 16 of weight 15. It will be apparent that the number of weights can be varied as desired.

An operating lever 11 is positioned in one 4 of the legs 9 pivoted as at 17, and provided 60 with an arm 18 extending upwardly within the housing 10, and provided with a cross arm 19 to which is secured a plurality of fingers 20, one for each of the weights 13, 14 and 15. r The fingers are adapted to engage simultaneously with the rack 16 of the weights, and to be moved out of engagement with the racks by depression of lever 11.

To elevate the weights within thehousing 10, a lever 12 is provided pivotally mounted within housing 10, as at 25, and having an arm 26 within the housing to which is secured a cross bar 27 extending under all of the weights.

In operation, the present device is ready for use when lever 12 having been operated, bar 27 will have raised all of the welghts in unison to the top of housing 10, as illustrated in Fig. 4. In this position, by releasing the tension on the cord 5, the music holding arm 4 will have been rotated by springs 4' to the right hand side of the music shelf. It being desired to turn the first sheet of music, lever 11 will be depressed by the operators foot, thus retracting fingers 20 from enga ement with the racks of all of the weights. eight 13 being otherwise unsupported, will descend operating through its cord 5 the music holding arm to which has been secured the first sheet of music. As weight 13 reaches the bottom of casing 10 and the end of its operative course, trip 21' will engage pawl 21 and disengage same from rack 16 of weight 14, and hold the same disengaged. It being desired to turn the second sheet of music, lever 11 will be again depressed, thus again withdrawing fingers 20; whereupon, weight 14, being otherwise unsupported, will descent, thus operating the second music holding arm.

Pawl 22' will, at the end of the descent of weight 14, disengage pawl 22 from the rack of Weight 15, which will then be unsupported otherwise than by fingers 20. It being desired to turn the third sheet of music, lever 11 will be again depressed, withdrawing fingers 20 from the rack of weight 15, which will descend, thus rotating the third music holding arm. Lever 11 is returned to normal position immediately after its depression by spring 24.

Various modifications in the structure and arrangement of partswill readily sug 'est themselves to those skilled in the .art, within the scope of the present invention.

Having thus described my invention, what I claim is: V j V '1. In-amusic turner having a plurality of music supporting arms, independent operating means for each of the arms, a release device for the said operating means operated by a single lever and including locking devices for said independent operating means, trips carried by the operating means adapted to unlock said locking devices whereby operation of one of the operating means will release the locking device of the next adjacent operating meansand means including a single lever for returning all of the operating means to normal position concurrently.

I 2. A device as specified in claim 1 in which each operating means includes a weight, said weights arranged side by side and in which the release device includes an independent supporting device for each of the weights except'that on one end of the row, and trips on each of the weights except that on the row, each trip adapted to disengage the pawl of tlllie next adjacent weight by contact therewit 5. A device as specified in claim 1 in which each operating means includes a weight, said weights arranged side by side, each weight provided with a rack, the release means includes a lever having mounted on one arm a plurality of pawls adapted to engage the racks of the weights simultaneously, and the selective means includes pawls one for each 'of'the weights except that at one end of the row, each pawl engaging the rack of its proper weight, and trips carried by each of the weights except that at the other end of the of the next adjacent weight by contact therewith, and the means for returning the weights to normal position comprising a lever carry ing on one arm arod extending under all of the weights.
