3 Claims.

My invention relates to reels provided, for exj "ample, for the winding thereon of electric cable, or the like, and more particularly to reels formed ;of spacedapart heads and an interposed drum portion of metal secured thereto, as for example by tie rods extending from, head to head through inwardly extending portions at the ends I of the drum.

V X My object, generally stated, is to improve upon I constructions of reels of the character above referred to as hithertolprovided to the end of producing a construction which will afford better service and be more economical of manufacture and of lighter weight, than constructions as ihitherto provided.

More specifically stated, one of myobjects is to provide a' construction whereby the cylindrical side-wall of the drum may be constructed of high I carbon sheet steel presenting such high degree of stiffness as to be immune from denting in use even when provided of relatively light gauge, 1 such as for example No. 16 gauge and which may 7 g be used to advantage in cable reels of drum diamete'rs of approximately '48 inches or less and load capacities up to approximately 6 tons; and provide for high resistance of the drum strucrture to shear.

Another more specific object is to provide a structure having the attributes just described which will present the desired rigidity and which may be fabricated at the minimum expense.

Referring to the accompanyingdrawings: Figure 1 is a view in side elevation of a reel embodying my invention.

the drum structure; and

Figure 6, a fragmentary sectional view of the structure of Fig. showing a detail thereof.

Referring to Figs. 1-4 of the drawings, the construction shown therein comprises a pairof circular heads 1 and 8, each shown by way of example, as formed of wood provided in three I laminations, and an interposed drum 9, the heads and drum beingsecured together as hereinafter described. s I I -The drum 9 which'is made of metal may be formed in any suitable way from sheet metal,

' such as for example sheet steel and more particularly high carbon sheet steel as it is much less susceptible to denting than the low carbon steels, the ends of the drum in the forming of the latter being drawn to provide shallow, inwardly extending, preferably continuous, flanges III.

The drum 9 also comprises metal rings II 5 cated in the drum at its ends, these rings which extend transversely of the drum as shown fitting I at their outer margins into the interior annular angles formed at the junctures between the body of the drum and the flanges I0. which may, by way of example, be made of low carbon steel, are of a thickness relatively great compared with the thickness of the sheet metal of the drum 9, and of a depth much greater than the flanges III in the particular construction given 16 aboveas an example, the rings being, by way of example, /8" or thick with a depth of from 2" to 2 7 The rings I I are secured to the drum as by tank welding these parts together at intervals say of 80 about 6" either along the inner faces of the rings I I at the joints between their circumferences and the cylindrical body portion of the drum as represented at I2, or along the outer faces of the rings I I at the joints between them and the inner 35 edge portions of the flanges ID as represented at I3.

The heads 1 and 8 and drum 9 are shown as secured together by the tie bolts I4, which extend continuously through openings in the heads I and 8, lined with flanged bushings one of which is shown at I5, and through openings, one of which is shown at IS, in the rings I I, the flanges I0 being so shallow as to reach short of a position in which they are intersected by the tie bolts I4.

The provision of the flanges III on the drum greatly facilitates the securing of the rings II in proper relation to the drum wall rendering unnecessary the continuous seam welding of the rings in position. The flanges ID to serve their purpose may be made very shallow as disclosed, reaching short of the tie bolts, and this permits the drum to be formed from high carbon sheet steel with the advantages above noted.

The desired thickness of metal at the ends of the drum to resist shear at the bolts I4 may be provided, without regard'to the gauge or kind of metal of the drum wall, by reason of the provision of the rings II as described. Thus I am enabled to avail myself of the advantage of using high carbon steel for the circular body portion of the drum to prevent denting, while providing the necessary thickness of metal at the bolt holes in the drum to present the desired resistance to The rings II 10 shear; a condition not possible of attainment where the bolt-engaging flanges of the drum are formed by turning inwardly the ends of the metal sheet of which the body of the drum is formed, except by forming the drum wall of such thickness as to render the reel expensive to manufacture and of objectionable weight.

Instead of providing the inwardly projecting separate portions at the ends of the drum as v members for securing together said drum and endless one piece members as represented of the rings H, they may be formed as sectional rings,

as for example as illustrated in Figs. 5 and 6.3.

In this construction the rings II are replaced by circular series of sections together forming annuli positioned relative to the inwardly extending flanges IE1 in the ends of the drum and se cured to the drum as shown and explained of the rings I I. forming one of the rings, is shown One of such series of sections,

at" l1,the sections of which, provided, by way of example, one

for each tie bolt with an opening l8 therefor, being in the formof chordal segments I9 which preferably are'welded together at their adjacent ends as represented at20 and more clearly illustrated in Fig; 6; and to the drum either at their, inner or outer faces as described of the construe tion shown in Figs. 1-4.

While I have illustrated and described certain particular embodiments of my invention, I do not wish to be understood as intending to limit itj thereto as'the same may be variously modif ed and altered and the invention embodied in other spirit of my invention.
