CHARLES. v. JAMESON', or CHICAGO, ILLINOIS.
TAKE-UP SPOOL FOR MUSIC-SHEETS.
Application filed August 225, 1917.
To all whom it may concern:
Be it known that I, CHARLES V. JAMESON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Take-Up Spools for Music- Sheets, of which the following is a specification.
This invention relates to the spools upon which the music sheets of'automatic musical instruments are wound, and more particularly to the take-up spools. I
Heretofore, such spools havelbeen provided at one endwith a stationary head or flange and at the other end with a spring-pressed flange intended to compensate for variations in the widths of difl'erent music sheets as well as shift the sheet against the face of the stationary flange to cause it to track properly, the stationary flange being located at a predetermined distance from the adjacent wall of the tracker-box for that, purpose. The yieldable flange is formed in one piece and therefore bodily movable with relation to the opposite flange. This construction is unsatisfactory, it being found in practice that if the spring of the movable flange is light enough to avoid binding or fraying of the edges of th music-sheet, it is not strong enough to shift the sheet againstthe stationary flange.
It is the object of my invention to provide a spool of this character which accurately and reliably guides the music sheet and yet exerts so gentle a lateral pressure against it as to leave its edges smooth and intact.
In the accompanying drawings:
Figure 1 is a front elevation of a tracker box equipped with the improved spool. Fig. 2 is an enlarged cross section thereof in connect-ion with a music sheet and a tracker. Fig. 3 is a fragmentary sectional elevation of the spool on a further enlarged scale. 4 is an end view of the spool, omitting the spring of one of the flange-segments. Fig. 5 is a side elevation of a modified construction of the spool.
Similar characters of reference indicate corresponding parts throughout the several views.
1 indicates the tracker box or frame, 2 the music spool, 3 the take-up spool and 4 the tracker board. In the drawings, the improvement is shown in connection with the take-up spool, but it is equally applicable to Specification of Letters Patent.

Serial No. 187,683.
the. music spool and other sheet-guiding spools or rollers.
. At one end the take-up spool is preferably provided with the customary stationary head orflange 5 arranged in the usual predetermined relation to the adjacent wall of the tracker box or the row of ducts in the trackerboard. At its opposite end the spool carries a head or flange cooperating with the fixed flange 5 and composed of a plurality of yieldable or spring-pressed sections 6 movable toward and from the fixed flange and tending constantly to shift the musicsheet against the same to insure its proper tracking. The yieldablc flange is also adapted to accommodate itself to any imperfections or dimensional variations of the music sheets due to climatic influences or other causes. In its preferred form the yieldable flange comprises a circular series of radial segments or sectors movable lengthwise of the spool, independently of one another, and each having an individual'spring 7 for pressing it inwardly or toward the fixed flange. In the embodiment of the invention shown in the drawings, the segments are arranged to swing lengthwise of the spool, and for this purpose each segment is pivotally attached thereto by a headed pin or nail 8 driven into theend of the spool and passing loosely through an opening 9 in the inner portion of the segment. Between its ends each seg ment is provided with a radial slot or opening 10 through which passes a guide pin or screw 11 projecting from the end of the spool. The springs 7 are applied to these guide screws between their heads and the outer sides of the segments. The springs are preferably of the conical or volute type and their bases are countersunk in circular recesses 12 in the segments, as shown in Fig. 3. Other kinds of springs may be employed if desired, but I prefer those shown on account of their neatness and compactness and their uniform .bearing against the segments on all sides of the guide screws 11.
In the use of the improved take-up spool, if the traveling music sheet on approaching the spool is more or less out of its true tracking course, it is restored to its central position by the action of the spring-pressed segments which successively engage the edge of the sheet and gently and gradually shift it toward and against the face of the fixed spool-flange 5, This restoring action of the sheet takes place Whenever it tends to swerve from its proper course.
To facilitate this action, the flange-segments preferably are normally arranged in an inwardly tilted position, as shown in Fig. 3. They may be caused to assume this position by any suitable means. The devices shown in the drawings for this purpose consist of collars or Washers-13 mounted on the pivot-pins 8 between the straight end of the spool and the inner portions of the seg ments.
By einp'loyiirgsuolr asectional or segmental spool-flange in connection with iridivid ual springs for the segments), the springs may be made so! light that the pressure of thesegnients will not fra or displace the edges of the meat sheets; At the same time, the springs are-siitliciently powered to center the sheet when displaoed,-i1'1asinueh as the segments do not operate simultaneously but act successively upon the sheet, shiftin it gradi'ially by a number of light taps or 1mp'ulses- Instead of making'ene of the spool flanges stationary, both flanges may be yieldable or spring-pressed, if desired, as shown in Fig; 5. In this case both flanges operate to center the sheet. I
