RESPOOLING 'DEVICE FOR MUSIC-ROLLS.

Specification of Letters Patent.

Patented Aug.l 23, 1910.

Application tiled December 18, 1907. Serial No. 407,025.

To allwhom fit may concern:

Be it known that I, GEORGE HowLnT'r DAVIS, a citizen of the United States, residing in the town of Vest Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Respooling Devices for Music- Rolls; and I do declare the following to be a full, clear, and exact description of the same, such as will enable those skilled in the art to which it pertains to make, construct, and use the same.

My invention relates to devices for respooling perforated music rolls of the character and kind used upon so-called automatic or player pianos. In the manufacture of music rolls of this character the rolls of paper to be perforated are fed into the perforators in layers frequently as many as sixteen-ply, that is to say, sixteen rolls of paper have their ends inserted into the perfor-ating machine, and the sixteen rolls are operated upon simultaneously. If the sixteen-ply were immediately wound up in a single sixteen-ply roll, the paper would become so distorted and buckled as to render the individual rolls useless. It is necessary, therefore, that the complete gang of sixteen rollsshall be re-spooled or re-wound into individual rolls.

I will now proceed to describe this speciiic mechanism forlning my invention.

Figure 1 is a side elevation of the complete structure. Fig. 2 is a plain view partly in section. Fig. 3 is a detached View of the feed roller locked.

The structure is composed of the supporting frame 1, upon the upper side of which and near one of its longitudinal edges are mounted the two semicircular spindle supports 2 and 3, secured to the corners of the frame in any convenient or desired manner.

Pivotally carried between spindle supports 2 and 3 are the several spindles 4, there being in the example illustrated sixteen of such spindles, which project forwardly or toward the front side of the machine and over-hang the main portion thereof, as illustrated in Fig. 2.

Between the semicircular supports 2 and 3 and secured to each individual spindle is a pulley 5, so arranged that all of the pulleys lie in the same vertical plane. Mounted upon the top of the frame 1, near one end thereof is the shaft 6, such shaft carrying upon its outer end a fly-wheel or pulley 7,

and near its inner end the pulley 8, which is I with a drive pulley so as to be driven bv means of belt power. Located substantially in the center of the circle formed by the two spindle supports 2 and 3 are the two tension pulleys 10 and 11, the pulley 10 being mounted in fixed bearings 12 upon the upper side of the frame, while the pulley 11 is mounted upon a pair of swinging arms 13, located on the inner face of the upper members of the frame 1. These arms are held Linder spring tension by means of the spring 14C one end of which is secured to the outer end of the arm 13, while the other end is secured to the frame member 1.

In order to hold the pulleys 10 and 11 separate during the process of threading up the machine, I provide the pawl 15 upon the inside of the frame, said pawl having a pair of notches to engage the shaft of the pulley l1, as clearly indicated in Fig. 3. Upon the right-hand side of the frame as indicated in Fig. 1, I mount a table 16, extending from the edge of the frame beneath the tension roller 10, and provided with the adjustable guides 1'7'at its edges.

At the outer end of the table and secured to the edge of the frame,'as indicated in Fig. 1, -I secure the roller racks, such racks com risin the two arms 18. havin a plu-- rality of spindles or rollers 19 mounted therein. At the opposite side of the frame 1, I mount another inclined table 20, such table being so located as to cover the shaft 6, and thus protect the same from contact with the music rolls.

If desired, a belt tightening device, such asillustrated in Fig. 1, at 21, may be ro# vided to take up the-slack in the belt 9 heretofore referred to.

In the use of my improved re-spooling machine, the perforated music rolls in the form inwhich they come from the perforating machines are in racks or trays, such as that illustrated at 22, the combined series of rolls being held together by means of the ordinary paper clips and lying loosely folded in such racks 22. When ready for spooling the upper or outside end of the bunch of perforated paper 23 is carried up and threaded over and under the several spindles 19, whence it is carried across the table 1G between the adjustable guides 17 and beneath the roll 10, it being understood that the ends are carried between the rolls 10 and 11 while the roll 11 is held away from the roller 10 through the pawl 15. The combined ends of the rolls are then carried forward and laid upon the table 2O when each one is taken up separately and carried over to the right, as shown in Fig. 1, and given a turn or two around the first spindle at the right. The second layer is then taken and iven a turn or .two upon the second spindle and the third to the .third spindle and so on until the entire number of .layers of paper are started upon the spools. Vhen so started the completion of the spooling is effected by the rotation of the shaft G by the crank upon the end thereof.

In the spooling of perforated rolls of this character I have found that it frequently happens, from one cause or another, that one of the layers of paper will begin to wind a little vmore rapidly than the others. If some means were not provided for maintaining a uniform tension in that portion of the several layers of paper 23 lying between the spindle and the tension rollers 10 and 11 there would result a buckled and crinkled effect in those particular layers of paper having the least tension. I have found, however, that in arranging the individual spin dles horizontally, and collectively, in a semicircle with the belt 9 lightly contacting the periplieries of the several `pulleys 5, should undue tension exist in any one or more of the layers, then the belt would slip over the corresponding pulley until the tension would be equalized in all of the several layers during the said winding process. It is this slip of the belt resulting in the proper regulation of the tension that constitutes the successful operation of the machine.

When the bunch of paper is completely wound, the rolls are taken off from the several spindles, when they are ready for the next step in their process of completion and a new tray full of unwound rolls is prepared for re-spooling in the manner hereinbefore set forth.

In order to facilitate the starting of a layer of paper upon the spindle, I provide each of the spindles with diametrical notches 24 to receive corresponding pins upon a crank 25, such crank being detachable from each of the spindles and successively applied thereto for the purpose of starting the end of a layer upon the corresponding spindle.

In order that the belt may have a uniform bearing upon the active spindles 5 at the ends of the supporting frames 2 and 3, I prefer to insert two terminal pulleys 26, so that the belt or band 9 will have no greater area of contact upon the terminal pulleys 5 than upon the intermediate pulleys. It will be readily seen that if the belt or band 9 passed directly from the drive pulley 8 to the terminal spindle pulleys, there would be agreater area of contact between such band and said pulleys resulting in a reduced tendency to slip under tension of the terminal rolls.

I believe that I am the first to produce a re-spooling device for music rolls or other multiple layers of paper of the character heretofore described, wherein provision is made for uniform tension in the several layers by means of a slip belt, and I, therefore, desire to claim such a device broadly.
