REEL.

SPECIFICATION forming part of Letters Patent No. 527,368, dated October 9, 1894.

Application filed May 31. 1 8 94:-

To all whomyit may concern.-

Be it known that we, CHARLES S. GOODING, of Brookline, in the county of Norfolk, and

. WILLIAM, E. G. GouDEY, of Melrose, in the In the drawings accompanying this specification, Figure 1, is an elevation of the reel, on the side where the driving attachments and connections are made. Fig. 2, is a section of the upper part of the reel on line 1- 1, Fig. 1. Fig.2 .,is a central section through the retaining disk and its bearings at the top of the reel, on line 2-2, Fig. 1. enlarged detail of a portion of one flange of the reel and the ratchet teeth thereon, and

the mechanism for holding a detent and retaining disk, near the bottom of the reel. Fig. 3 is a diametrical section of said retaining disk. Fig. 4 is an end view of the pulley,

pawl and ratchet by whichthe apron roll is turned to Wind up the apron when the plastic sheet is removed from the reel, and of an idler roll to keep the driving belt of the apron roll in proper tension. Fig. 5, is'a central vertical section online 3-3, Fig. 1, of the drivingpulley and ratchet on the apron roll shaft. Fig. 6, is a detail showing a clutching device by which the driving mechanism is connected with the reel, instead of using the pawl and ratchet. Fig. 7, is a section through said clutching device.

Referring to the drawings, in which similar letters or figures are used to indicate the same part of the machine wherever it is represented, A is the reel supporting frame; B,

the drum of the reel; 0, the disk flanges the inner surfaces of which are inclined outward from the drum toward the rim, and have a series of pockets 10 arranged spirally around Fig. 3 is an- Serial No.513,029. (No model.)

such inner surfaces. The reel is also provided with a flexible apron D, having rods 1- attached thereto at intervals corresponding to the distance between successive pockets in the flanges of the reel. These rods project beyond the flexible apron, so that their ends may readily enter the pockets'when the apron is wound upon the reel, and they vary consecutively in length, to correspond to the increase in distance between the inner surfaces of the flanges of the reel, from the drum B toward the rims.

. The improved mechanism for drivingsaid 1 reel consists in an annular ratchet E which may bemade in sections and attached to one of the said flanges, and an arm F pivoted upon the reel axle, and carrying one or more pawls G at its outerend which engage with the teeth of I the ratchet E.

The arm F is preferably connected to the driving mechanism of the machine to which the material upon the reel is to be fed, and

in Fig. 1 it is illustrated as being connected by a rod H, to one arm of acrank-leverI, and'l by means of a rod K the other arm of said lever is connected with the eccentric which drives the blank cutting knives of a machine, such, for example, as that described inLetters Patent No. 444,982. r The arm of the crank-lever I with which the rod K is connected is slotted at i, to facilitate the adj ustment of the stroke of that lever.

I In the outer side of the flange to whichthe annular ratchet is attached'a groove L is formed in a spiral path which substantially conforms to the convolutions of the apron D when it is wound upon the reel, indicatedin L dotted lines in Fig. 1, and is supported there by its attached rods which rest in the spirally arranged pockets. The rod H is hooked upon a pin m, which passes through a grooved block 71 constructed so as to slide readily, ina slot N formed in thearm F. Upon the inner end of the pinm,

isla small friction roll 0, which runs in the spiral groove L. The roll 0, is kept in the groove L, by means of a retaining diskP.

which may conveniently be supported upon I l. the spindle of one ofthe pawls G, in such a the inner surface of the flange C, and for the purpose of providing a yielding pressure of the disk P, a spring Q, is placed upon the outer end of its supporting spindle. a

When the flanges O are made of wood, for the sake of lightness and economy, they are liable to warp, and in' order that the arm F may readily accommodate itself to such unevenness, itis provided with a double hear ing upon the axle of the reel; consisting of an inner sleeve S which fits that axle and an outer sleeve T, integral with the arm F, the bore of which outer sleeve is somewhat larger than the outer diameter of the inner sleeve, and pins Mat right angles to the arm F, which join the two sleeves together, thus allowing the said arm to swing in a short are to and fro in'a plane which passes through the axis of the reel shaft.

R is a detent pawl held against theratchet E by a spring 8 to prevent the reel from turning backward. The middle portion of this spring is broken away in Fig. 3. This detent, as also a retaining disk, R is hung upon a swinging arm V, pivoted torthe frame of the reel and which is constantly pressed toward the reel by a crooked arm W, and spring w. The sleeve which carries the detent B, and disk R is loose upon the arm V, and they are kept in proper position by a groove in the edge ofone flange of the reel in which the disk R runs.

The apron roll X is turnedby a band 6, which runs in the groove 9, in the flange of the reel and in a groove. in a pulley You the shaft of the apron roll X. The pulley Yis loose on the shaft of roll X and carries a pawl m, which engages with a ratchet wheel Z fixed to the shaft of roll X, sothat when the pulley Y is turned to the left as indicated by the arrow in Fig. 4, the roll X will be revolved and the apron wound upon it, but when turned in the opposite direction the pawl x, will run over the teeth of ratchet Z and the-roll X will remain stationary. The band I) is loose and the proper tension is given it by a tightening pulley y, on an armwhich may be adjusted by a screw, 2.

When the flanges of the reel aremade of wood it will be found advantageous to strengthen them by a wire 5, secured about the rim of each.

The operation of the improved mechanism is as follows: Having adjusted the rod K in the crank-lever I so asto obtain the length 0 f stroke desired, for example, six inches for the upper end of the part '5 of said crank-lever, each stroke ,of the lever I will move therod H and with it the block n, and slotted lever F, six inches forward and back. The pawl G upon the upper end of the lever F, being in engagement with the teeth of the ratchet E on tent R, the backward movement of the lever F will cause the pawls G to run over the ratchetteeth. The backward movement of the lever F will also move the friction rollo ..(Fig. 2)- along the groove L in the outer surface of the flange of the reel, and as the roll 0, is moved along the said spiral groove from its outer convolution to those nearer. the center of the reel, the block or, will slide down the groove N, in the lever F.- It will be seen therefore, that as the spiral groove 112 is, Substantially coincident with the convolutions of the mechanism upon the reelwi-ll be automatically adjusted so that its point of connection therewith will always be at the outer convolution of the material remaining thereon irrespective of the amount, the same amount of material will be unwound at each stroke of the leverl.

Although the revolution of the reel is unifform and consequently of the apron roll X, and pulley Y, the increased pull of the rollX ;upon the apron, incident to the increase in its ithe pulley y, that as soon as the slack of the iapron is wound up, the band I), will slip upon lthe pulley Y, and relieve the mechanism from any injurious strain. 1 In place of the lever F and ratchet and ipawl E, G, a clutching device to slide inand engage with the groove 1. may be employed and to which the rod H may be connected. A simple form ofsuch a. clutchingdevice is illustrated in Figs. 6 and 7, and consists of'a Eair of arms a, a, of a shape similar'to one f alf of a horse-shoe, pivoted together as at the toe 8. A pin 9 is inserted through the space between the arms a, a, and has a disk flange 10, upon its inner end for which'an ad ditional grooveis made-in the flange of the reel. The forked end of the-rod His hooked .over the outer end of the pin 9, and is held in place bya washer 12.

It will be understood that when the rod H is moved toward .the reel, or to the-left, the

pin 9 will slide between the arms a, at, until it strikes them at the pivot 8, when the said clutching arms will be pushed along the groove L. When the rod- H is moved to the right, or away fromthe reel, the pin 9 will gradial leverage caused by the winding up of I ithe apron thereon, is compensated forbygiv- I iing the band I), such'a tension by means of slide between the arms a, at, until it spreads them sufficientlyto cause them to bind in the groove L, when the reel will be-turned during the remainder of the stroke of the crank lever I. i

We claim- 1. A reel having a spiral groove in the sur face of one of its-flanges, a traveler to run in said groove, mechanism. connected with" the, i

traveler to give it reciprocating motion, and devices to interlock with the reel and move it with said traveler when the reciprocating mechanism moves in one direction, and to release and leave the traveler free to move alone when said mechanism moves in the other direction.

2. A reel provided with a groove in the outer surface of one of its flanges which corresponds substantially with the convolutions of the material wound thereon, a traveler to run in said groove, mechanism connected therewith to give it reciprocating motion, a ratchet upon the reel anda pawl to engage the teeth thereof, which is controlled by said reciprocating mechanism, whereby when said mechanism is moved in one. direction the reel will be turned and when moved in the other diwith and with said pawl-supporting lever, for the purpose described.

4. A reel having a spiral groove and an an nular ratchet on one flange, a traveler to run in said groove and a pawl to engage said ratchet, a lever pivoted at the reel axle which carries said pawl and a retaining disk which overlaps the inner surface of the flange, and mechanism to give said traveler and pawlsupporting lever,r eciprocating motion,whereby the reel will be rotated a constant prescribed distance at each alternate stroke of said reciprocating mechanism for the purpose described.

5. A reel having a spiral groove and an annular ratchet on one flange, a traveler to run in said groove, and a pawl to engage said ratchet, mechanism to reciprocate said traveler and pawl and a detent to hold the reel from retrogression substantially as described.
