1o claims.

The present invention relates generally to the reel art and particularly to new reels for cable and the like and to new lagging for such reels.

Reels embodying the present invention comprise a small number 0f inexpensive parts or as- 'semblies including a hub and ends. The ends :comprise sheet metal assemlbies which are secured to the hub and may carry bushings or be attached to an inner hub. The peripheral portions of the ends are of reinforced construction and are adapted to fit lagging which may be connected thereto. Reels of this invention may be light in weight and yet strong enough for initial loading and for handling and shipping while loaded and may be so low in cost and assembled that they may be economically scrapped after their initial load is removed. They may also be heavier and stronger and suitable for repeated loading, handling and shipping.

The present invention will be better understood by those skilled in the art from the following description and from the drawings which form a part of the specification and in which Figure 1 is a fragmentary end view, partly in section, of one form of apparatus embodying the present invention;

f The reel shown in Figs. 1 to 4 comprises an inner hub, an outer hub and two end assemblies or yuntis. The inner hub i is -a cylindrical tube with ends 2 which are dared outwardly daring assemv bly with the end assemblies or units. It is surrounded by a sheet metal shell 3 which, at each end, abuts the end assemblies and acts as an axial stop and spacer therefor. The outer hub d, on which cable or the like is to be Wound, is la sheet metal cylinder of considerably larger diameter than the inner hub l. The ends of hub 4 are recessed to provide projections 5 which are secured, as by welding, to the end assemblies and serve, together with the ared ends of hub l, to hold the end units in place relative to the hubs.

Each end unit or assembly includes an inner, metal ring I ll, an annular, metal, reinforcing angle il, a segmental, metal disc l2, and gussets i3. The ring lil seats at its inner periphery on the outer surface of outer drum i and at its outer periphery is bent to form an axially extending flange l i which, during assembly, is provided with an inturned flange l. The angle Il bears against and is secured to the inner surfaces of ring i@ and its ange it.

The segmental disc I2 consists of a plurality of sector shaped units or segments ZIJ. Each unit 2@ is preferably formed from sheet metal and includes a at face portion having Iperipheral flanges and a radially extending depression 2i.

The outer peripheral ange 22 of unit 20 is shaped by being curved to nest within the flanges it and i5 of ring lil and to bear on ring It. The peripheral fianges 23 along the sides of unit 20, that is, along radii of the end units, extend to and bear against the opposed surface of ring it for part of their lengths. These flanges are of greater axial extent within outer drum i and bear against the inner surface of that drum, as is indicated at 2d. Each flange 23 is provided with tabs 25 which extend laterally therefrom and project thru notches in the flanges of adjacent segments 2li. The inner peripheral flange 26 of each segment seats on the outer surface of inner hub l land :bears endwise against shell 3 on that hub. As will be noted from Figs. 2 and 3, the depressed portion 2i of segment 2U bears against the opposed surface of ring lll and has openings 2 therethru in line with the projections 5 of outer drum t.

A gusset i3 is associated with each segmental disc i2. Each gusset includes an outer flange t@ which bears against, and is preferably welded to, the inner surface of the peripheral ange 22, an inner ange 3| which bears against, and is preferably welded to, the inner surface of the fiat portion of segment 20 and an angularly extending part 32 connecting flanges 30 and 3 l.

The apparatus of Figs. 1 to 4 may be assembled as follows:

Reinforcing angle l I is placed in ring l0 and is attached thereto, as

by being welded to the ring .s l 3 and to its flange I4. The guSsets Il are placed in their segmental discs I2 and are attached thereto, as by welding flanges and 3l thereto. Then the several thus assembled segmental units are placed on ring Il and are attached thereto, as by welding tabs 25 to ring I0, and flange I4 is shaped at its edge to form flange I5 which grips the segments at their outer edges. One end of inner hubk I is fitted into one end assembly and is deformed as at 2, to grip the outer side of the assembly. Shell 3 is slid onto hub I to abut that end assembly. The projections 5 of outer hub I are inserted thru openings 21 in the end assembly and are bent over to clamp the assembly against the drum. Then the other end assem-bly is secured in place at the opposite ends of hubs I and 4 in asimilar manner. i

The embodiment of the present invention illustrated in Tigs. 5 to 'l generally resembles that of Figs. 1 to 4, but certain elements of that modification have been omitted and others altered. The reel of Figs. 5 to 6 comprises a hub 40 of large diameter and end assemblies attached' thereto. Each assembly comprises an inner ring 4I which, at its inner periphery, seats 'on the outer surface of drum 40 and, at its outer periphery; has an axially extending flange 42 and an inturned flange 43. Each segment 44 is formed' from a at metal plate having a radially'extending depression 45 and marginal flanges 46, 48

and 50. The outer peripheral flange 46 is of such a size as to be received in the channel rim of ring 4I. that is, Within flanges 421 and 43 and, if desired, a reinforcing angle may lie between flanges 46 and 42, substantially as shown in Figs. l to 4. The side flanges 48 of segments 44 extend toward and engage the surface of ring 4I. Flanges 48 within drum 40 are of slightly greater'axial length than the parts thereof opposed to ring 4I and bear radially against the inner surface .of drum 40, as is indicated at 49.A The inner peripheral flanges 50 of the several segments of an end assembly define an opening 5l in which a flanged bushing 52 may be secured. The side flanges 48 are provided with tabs 53 which project thru notches in the opposed flanges of adjacent segments and are welded to those adjacent segments, as by means of an electrode or welding rod inserted thru openings 54 in the segment above the tabs. The depressed portions 45 of segment 44 lie against the opposed surface of ring 4I.

The ends of the drum 40 have projections 55. When the end assemblies are to be assembled with drum 40 the projections 55 of the drum are passed thru opening 60 of the end assembly and rings 4I are seated on drum 40 with the enlargementsof flanges 48 bearing against the inner surface ofthe drum. Wedges 56 are inserted thru openings in projections and driven into place to connect the end assembly to the drum.

It will be understood from the drawings and the foregoing description thereof that the illustrated reels are light, strong and quite substantial altho composed of parts which in themselves are not particularly strong. The drum on which cable or the like is wound is adequately supported at its ends both on its inner and outer surfaces by the flanges of the disc segments and by the inner rings. The end assemblies are substantial althocomposed of a plurality of parts. kThe segments have a considerabledegree of rigidity because of their flanges and such rigidity is increased by the ring and its channel-shaped outer periphery. The parts of the end assemblies are 4 Y attached together by welding and by being interfltted with one another. When the reel includes an inner hub it also adds materially to the strength and rigidity of the reel and when gussets are used they additionally support the periphery of the end assemblies. Similarly, the reinforcing angles add rigidity to the peripheries of the end assemblies.

In the modifications shown in Figs. 8 and 9 the hub consists of two semi-circular parts having radial inturned flanges BI which are connected by bolts 92. The in turned ends 93 of thehub are connected by bolts 94 to ends 95. Rivets or other suitable connecting means may be substituted for bolts 92 and 94 if desired. Also hub 90 may be made of a single piece of metal, or it may consist of three or more parts instead of the two parts shown in Figs. 8 and 9.

Each end 95 consists of a plurality of sectorshaped, sheet metal units, in this case four. These units have outwardly projecting, marginal flanges 96, the radial portions of which lie against each other and are connected together by bolts 91. The inner or opposed plane surfaces of ends 95 bear against flanges 93 of the hub. The flanges 95 at the inner extremities of the segments of each end 85 define an opening in which a flanged bushing 98 is located. Each sleeve has flanges at each end to bear against the inner surface of the segments and the outer surface of flanges S5.

The reel of Figs. 3 and 9 is inexpensive and may be disassembled for return shipment. It may be made strong enough for repeated use or only strong enough for one use. The flanges 95 and the recessing of ends 95 to receive hub 90 afford marked strength and rigidity even when the metal used is of light gage. It provides smooth surfaces for contact with a coil on the hub.

Figs. 10 and 1l show hub and end securing means alternative to those of Figs. 8 and 9. In this case the hub |00 is a cylinder which seats in a depression IIlI in the ends |02 and has spaced projections |03 extending thru ends |02 and held in place by wedges |04 extending thru the projections and bearing against the segments.
