3 Claims. (Cl. 242-72) My invention relates to reels for coiled material, more particularly to reels used for handling coils of sheet steel, and the principal object of my invention is to provide new and improved reels of such character.

The ordinary reel used in handling of coils of material, such as sheet metal, comprises a collapsible drum or mandrel which is contractible so that it may be easily inserted in the eye fof the coil and which is expandible so that it rmly engages the surface of the coil defining the eye.

In many cases the reel is aligned with other mechanisms. For example, when the reel is used as a pay-olf reel it may be aligned with a slitter or cut-off device. Under such circumstances, it is desirable to maintain the coiled material in predetermined alignment with devices in subsequent work order and such alignment has theretofore been dithcult to maintain because the coiled material might not always assume a predetermined relation on the reel o-r because the coil was not wound with the edges of the ysheet in alignment and an endwise bulge was formed which prevented the coil from assuming predetermined position on the reel.

My invention overcomes the ditliculties inherent in prior art constructions and makes it possible to maintain the coiled material in predetermined position on the reel, thus maintaining proper relation between the coiled material and subsequent material working devices.

In the drawings accompanying this specification and forming a part of this application, there is shown, for purposes of illustration, an embodiment which my invention may assume, and in these drawings:

Figure l is a central longitudinal fragmentary section of a reel embodying my invention, and showing parts in one relation,

Figure 2 is a sectional view `similar to Figure l but showing parts in another relation,

Figure 3 is an enlarged generally diagrammatic view, showing parts in one relation in full lines and parts-in another relation in dot-dash lines in order to provide clear comparison between the parts in the two positions, and

Figure 4 is a fragmentary end view of the reel shown in Figure l, parts being shown in section to better illustrate the invention.

Referring to the drawings, the embodiment of the in ventiron therein disclosed comprises a drum or mandrel which is adapted to support a coil of material, shown in dotted lines at C. The drum is contractible so that it may be readily inserted within the eye of the coil, and is expandible to firmly engage with the material defining such eye. i

In the embodiment herein disclosed, the drum is formed of four sections 11, each of arcuate cross-section so that when the drum is in expanded relation it forms a generally cylindrical member.

A shaft 12 is supported for rotation by suitable bearings 13, and this shaft may be freely rotatable, or may have connection with a friction brake, or may be motor driven, and since any of the foregoing may be of com- 2,762,577 Patented Sept. 1l, 1956 ICC mercial design, such construction is not shown. In the' embodiment disclosed, the shaft, and drum supportedl thereby, are supported in outboard-bearing relation so that the coil lof material may =be disposed over the drum by movement from the open end thereof.

A sleeve 14 is slidable longitudinally along the shaft 12 and is formed with four pairs of ears 15, 15a each pair being directed toward a respective lone of the sections 11. Each of the sections is provided with a pair of ears 16, 16a directed toward respective ears 15, 15a. Spaced links 17 are pivotally connected to respective ears 15a, 16a as by pivot pins 18, 19 and links 20, of H construction, are pivotally connected to respective ears 15, 16 as by pivot pins 20a, 21.

In the embodiment herein disclosed, the shaft 12 is formed with a longitudinal central opening and a rod 22 passes through this opening and extends outwardly of the free end of the shaft. A cap 23 is bolted to the sleeve 14 and the extremity of the rod 22 is threaded into the cap. A lock nut 24 prevents unintentional disassembly of the connected parts. The rod 22 may be moved longitudinally in any suitable manner, a suggested form being a uid cylinder (not shown) which has rotatable connection with the rod beyond the bearing 13. Instead of a uid motor, a nut and screw arrangement may be used to effect movement of the sleeve.

A face plate 25 is disposed transversely of the axis of the shaft 12 and is formed with a central collar 26 which, in this embodiment, is formed with four milled slots 27 which are 90 apart. The collar is secured to rotation with the shaft 12 by means of a key and keyway 28, and sleeve 14 is also secured to rotation with the shaft 12 by any suitable means, not shown, which additionally permits relative axial movement of the shaft 12 and sleeve 14.

In the embodiment disclosed, four long links 29 have pivotalv connection With the collar 26 and with respective sections 11, and as shown in the drawings each link 29 is pivotally secured within a respective slot 27 by a pivot pin 30. Each link passes between the respective pair'of links'17 and is pivoted to its respective section bythe pivot pin 21 which connects the respective H-link to its section 11.

The links 17, 20 provide parallel linkage which will cau-se the sections 11 to mrove toward or away from the axis of the shaft 12 depending upon the direction of movement of the sleeve 14 as actuated by the rod 22. Each link 29 causes its section 11 to swing in an `arc defined by the pin21 turning about the center formed by the pin 30 and since thelinks 29 are relatively long the arc will be relatively shallow. However, the arc is sulficient to move the sections toward the face plate 25 as the sections are moved away from the axis of the shaft 12.

In operation, the drum is collapsed by urging the rod 22 to the left7 as viewed in the drawings. Such action rrr'oves the sleeve 14 to the left, causing the links 17, 20 to pivot about their respective pivot pins and fold inwardly toward the sleeve 14. The long links, swinging through arcs 31 (see Figure 3) will cause the sections to move away from the face plate 25, as shown by the space at 32.

The drum or mandrel is now in position for receiving a coil of material, and such coil is assembled by moving it so that the drum extends through the eye of the coil. The coil is assembled so that its one side is positioned somewhat near the face plate, the exact position being unimportant, as will appear.

The drum or mandrel may then be expanded by urging the nod 22 to move to the right, as viewed in the drawings. Such action moves the sleeve 14 to the right and causes the links 17, 20 to move to straightened position as shown in Figure '1. The long links, swinging through the arc 31A will move the sections 11 toward the face plate and thus crowd the adjacent side of the coil against the face plate. In the event this side of the coil is bulged outwardly, such crowding action will tend to align the edges of the convolutions of the coil. Since the face plate may be accurately aligned with machinery in subsequent relation along the Work line, the coil will always be mounted in accurate alignment with such subsequent machinery.

In view of the foregoing it will ybe apparent to those skilled in the art that I have accomplished iat least the principal object of my invention and it will also be apparent to those skilled in the Iart that the embodiment herein described maybe variously changed and imodiiied, without `departing trom the spirit of the invention, and that the invention is :capable of uses and has advantages not herein specifically described, hence it will tbe appreciated that the herein 'disclosed embodiment is illustrative only, and that my invention is not limited thereto.
