DAVID WILLIAM HUDSON, O-F GREEN BAY, WISCONSIN.

REEL.

To all whom it may concern:

, Be it known that I, DAVID WILLIAM HUD- SON, a citizen of the United States, residing at Green Bay, in the county of Brown and 5 State of Wisconsin, have invented certain new and useful Improvements in Reels and I do declare the following to be a "full, clear, and exact description of the invention, such as will enable others skilled in appert'ains to make and use the .same. 1 4

This invention relates to winding and reeling, and more especially to reels which are capable of contraction; and the object 5 I of the same is to produce improved mecha- 1118111 for contracting the circumference of a paper-winding reel at each revolution thereof,- whereby the diameter of the roll of paper upon the reel will remain the same 20 regardless of the number of folds or thicknesses of paper'whi'ch it contains. This ob'-- ject is carried out by constructing the device in the manner hereinafter more fully descrlbed and claimed, and as shown the Figure 1 is a side elevation carpi-smachine complete, and Fig. 2 an en 'g'view thereof. Fig. 3 is a cross section on the line 33 of Fig. 1. Fig. 4: is" anenlarged lon- 30 gitudinal section through the retarding and gearing mechanism he'feina'fter described, and Fig. 5 is a cross section on the line 55of Figil. Fig. 6 is a perspective .detail of the parts shown in Fig. 5 slightly Mounted iii bearings 1 in a framework is a shaft driven by suitable means as at 11. This shaft is made up ofsections 2 of tubes connected at their -meeting ,endsby couplings 3, the couplings on contiguous sections being bolted together as at 4. Through its endinost face each coupling has a plu rality ofgrooves .5 in which move rack bars 6; and the outer ends .of the latter are connected tdcastings 7 which in turn are connec'tedin pairs by plates 8 curved in cross section andeoacting with each other to make up the periphery of the reel or drum proper 1 which of course may be as long and as large or small as desired. Throughout the v tubular shaft extends a solid shaft 12, and

at proper points in its length this solid shaft i is provided with teeth 10 adapted to mesh with the teeth of the rack bars or spokes 6,

for which purpose the spokes in any group are disposed tangential to the solid shaft.

the reception of paper rolls which are to be wound thereon in strip form, it becomes desirable that the circumference of the reel 7 shall be reduced at eachrevolution thereof in a manner at first abovesuggested, and

the mechanism for automatically reducing the size of the same by drawing the spokes inward, forms the subject of the present invention Keyed to the-outer shaft2 is-a collar 13, andloose on said shaft is a gear l l'having a hub 15 which projects toward and into contact with the collar 13. Surrounding said hub is a brake band 16, preferably having a lining 17 the band being in the form of aplit ring with cars 18 at its extremities which are drawn together by a hand screw 19'. Alongside the-brake band and between it and the gear 14:- a disk 20 is mounted loosely around the hub 15, and pins 21 pass through the collar, the brake band, and this disk so as to cause all three parts to rotatesimultaneouslm, while it will be clear that when the hand screw 19 is set up 'to tighten 'the brakeband' around thc hub'15, the rotation of said three parts will be. communicated also to the gear 14. The periphery of "the last-named gear may have ratchet teeth or ordinary teeth, but in any event they are adapted to be engaged by a spring-actuated pawl 22 carried by the frame as seen in Fig. 2, the disposition of thispawl being such that it checks thero- ,tation of the gear 14:,whereas the power imparted at 11 to the shaft 2: causes the rota-- tion of the other elements above mentioned and they must therefore slip where the lining 17 embraces the hub 15.' The periphery of the disk is cutrawayas shown at 23, but otherwise it is of a circumference ,slightly greater than that of the outer end of the teeth of the gear, and the width of the pawl 22 is such that ordinarily its tip lies on the circumference {of the disk and does not ongage these gear teeth. Alongside the disk is secured a sector 24'having a rounded front end or nose 25, and'by preference its body is provided with a slot 26 through which passes a screw 27 by means of-which this sector is adjustably, mounted against the side of the disk. .When now the sector is adjusted forward it reduces the distance between its nose and the forward end of the cutaway portion 23 which we will indicate at the point a; whereas the adjustment of the sector in the other direction increases said distance, which is the space that the gear teeth are exposed, for throughout the remainder of the periphery of the gear the disk or its plate projects beyond said teeth and the pawl cannot engage them. At the outer side of said gear isformed a second toothed hub 30, or this element may be anindependent gear fastened to the larger gear.

Meshing with it is a gear'31 which is fast on one end of a counter shaft 32 that is journaled in a plate 33, the latter being fast on the shaft 2. as shown. The other or outer end of the counter shaft 32 carries a smaller gear 34 meshing with a larger gear 35 fast-on the solid shaft 12. Finally, the extremity of this shaft is squared as shown at 37 for a purpose to appear. V 1

With this construction of parts,-the operation of the machine, is as follows: Power applied at 11; rotates the main sh ft 2 and the parts that are fast thereon, and y means ofthe set screw 27 the sector 24 can be set on the disk 20 to vary the distance between its nose 25- and the point a. The rotation of the gear 14in the direction of thearrow, which occurs by' reason of the'bandbrake '16 frictionally engaging its hub 15, finally brings the point a under the tip of the pawl '22 which engages the first exposed tooth and checks the rotation of this gear. Thereafter. the disk and the partsattached thereto rotate past the gear with the result that the,

' sector 24 moves toward and finally reaches the point a andits'nose 25 lifts the pawl 22' out of engagement with the gear so that the latter resumes rotation with the other parts; and this rotation will continue until the point a again comes under the pawl, when the operation just described will be repeated. While'said gear 14 rot-ates with the hollow shaft; there is no effectupon the solid shaft. but when its movement is interrupted as just described, the result is as follows The plate 33 rotates constantly with the; shaft, and this plate carries the counter shaft 32 and the gears 31 and 3a with it. As the gear 31 is in mesh with the hub 30 of the main gear 14, while said hub rotates with the shaft there is no effect on the gear 31', but when the hub temporarily ceases to rotate and the gear 31' continues to move, the result will be that this gear will turn backward for a few. teeth, and the rotation is communicated through the gear 34 to the gear 35 on the solid shaft 12. The latter' through the teeth 10 thereon" causes the retraction of the various spokes 6 so] that the size of the reel is reduced a trifle. Adjustment of the sector 24 so as to regulate the Leas es it may bedesirab'le to apply a wrench orother'square instrument to the end 37 of the inner shaft 12, and rotate the same rapidly in a reverse direction so as to distend the spokes 6 and enlarge the reelfor renewed use; -.and during this action it may be wise to loosen the hand screw 19, although the same is not absolutely necessary. The parts are of the desired materials, and it will not be necessary for the purposes of this specification to amplify the uses of such a reel.
