Application June 12,

9 Claims.

This invention relates to lagging for reels used for storing and transporting heavy material, such as lead covered cable, and more particularly to lagging provided with means for securing the lagging upon such reels.

Although not limited thereto, the present invention is particularly applicable to the securing of a series of sheet metal lags of substantially channel-like cross-section placed side by side across the outer peripheries or rims of metal reel heads to form a complete enclosure for the cable storage space of the reel, and particularly to reels wherein the outer edges of the rims are appreciably inside the end faces of the remaining portion of the reel heads. The rim engaging end portions of the spaced arms of the channel lags are preferably narrowed or reduced in depth by notching the bottom end corners of the arms whereby in addition to appreciably strengthening the lags against impact stresses longitudinal movement of the lags on the reel is efiectively prevented. The rim engaging end portions of the lags are reinforced by inserting and welding within each end portion of the lag a filler or liner in the form of a short channel member provided with an outer end wall.

An object of the present invention is the provision of an improved reel lag and simple secur} ing means therefor, whereby lagging may be readily and effectively secured to reels and easily removed therefrom.

In accordance with theabove object, the invention contemplates in one embodiment thereof, as applied to reels and lagging of the above mentioned types, lags each having at one end a portion adapted to be hooked over the outer edge of one head rim, the opposite end of the lag having a portion extending over the outer edge of the other head rim and terminating in an outturned flange. Encircling the lag flanges are a plurality of arcuate lag retaining metal strips, each strip being associated with a predetermined number of lags with opposite ends of the strips bolted to elements fixed to the head behind the ends of the strips.

In accordance with another embodiment of this invention the lags are similar to the lags described hereinbefore except that the portion at one end thereof which terminates in an outturned flange is formed to terminate in an outturned hook, the series of hooks being encircled by a lag securing wire rope or band which is first secured at one end to one of a plurality of predeterminedly spaced knobbed studs projecting angularly from the end surface of the reel head A.

and then entered into a number of the hooks on the lags, comprising a group, and thereafter around another stud and thence over another groupof hooks, the rope being applied under tension at each group, and thus continuing around the head until the entire series of lag hooks have been encircled by the rope, and finally securing the free end thereof to the first stud.

Other objects and advantages of this invention will more fully appear from the following detailed description, taken in conjunction with the accompanying drawings, wherein Fig. 1 is a view in side elevation of a metal cable reel provided with the improved lagging and means for securing the lagging to the reel embodying the invention;

Fig. 6 is a fragmentary side view looking at the left end of the structure shown in Fig. 5;

Fig. 7 is a fragmentary vertical section through a plurality of lags illustrating another embodiment of lagging, and

Fig. 8 is a detail section through one of the knobbed studs of the embodiment shown in Fig. 5.

Referring now to the drawings, a preferred form of lagging embodying the invention is illustrated, for example, in conjunction with a cable reel comprising a pair of spaced heads l0, interconnected by a drumv II for holding a lead covered cable '52, or other heavy material that may be wound thereon. The cable reel itself may be of any suitable construction, although a welded all-metal construction is preferred. In the construction illustrated, the heads each comprise an inner annular channel member I3, an outer annular rim l t concentric therewith, channel spokes l5 extending between the inner annular member and the rim and welded thereto, and an annular metallic disc or head sheet l6 welded to the spokes on the side facing the drum.

The spokes are notched at their inner ends, as shown in Fig. 2, to receive the ends of the drum and outwardly turned inner flanges ll of the head sheets, which, together with the drum, may

be welded to the annular channel l3. In the construction illustrated, the spokes I are also notched at their outer ends to receive outwardly turned outer flanges M of the head sheets, which may be welded to the under Side of the rims I4. The outer ends of the channel spokes l5, it will be noted, arenarrower than the inner ends thereof and thus the side flanges are inclined inwardly from the annular channel member I3 to the rim I4. This arrangement, wherein the outer edges of the rims are appreciably inside the end faces of the remaining portion of the reel heads, per-.- rnits the reel to be laid on its end face with the rim and the spokes and the lags, to be presently described, spaced from the ground or other support for the reel.

The preferred form of lagging embodying the invention comprises a plurality of lags 25 of uniform size and construction and suflicient in number so that when placed side by side on. the rims I4 and lengthwise across the width of the reel, as shown in Figs. 1 and 2, a complete covering or enclosure is provided for the cable storage space of the reel. The lags are preferably of channel-like cross-section and formed from sheet metal. Each lag comprises a substantially flat web portion 25 and integral depending side arms or flanges 21, 2'! on opposite sides thereof. .As best shown in Fig. 3, the flanges 21 are slightly flared outwardly and at their bottom edges they are formed with outwardly extending open beads to provide rigidity and are slightly resilient to transverse pressure, so that when a series of the lags are laid in place side by side on the rims of a reel and pressed together, the abutted head portions form a tight seal between the lags.

The lags 25 are placed on the reel so that the bottom edges of the flanges 21 thereof contact the rims I4, as shown in Figs. 2 and 3. The rim engaging end portions of the lag flanges 2'! are preferably narrowed or reduced in depth by notching the bottom end corners of the flanges, as indicated at 29 (Figs. 2 and 3). The resistance of the lags to impact stresses is thereby increased. Also, the notched corners permit the remaining unnotched portions of the lag flanges to project inwardly between the reel heads and thereby serve as braces therebetween as well as effectively preventing substantial longitudinal movement of the lags on the reel. To further increase the strength of the lags 25 and their resistance to impact stresses the rim engaging end portions of the lags are reinforced by increasing the wall thickness thereof by inserting and welding within the end portions a filler 30 in the form of'a short metallic channel member of a cross-section substantially conforming to the cross-section of the notched end portions of the lags. Each reinforcing channel member 30 comprises a web portion 3| and a pair of depending side arms or

flanges

32, 32, which at their bottom edges are flush with the bottom edges of the notched end portion of the lag flanges which contact the rims I l. channel fits snugly within the notched end portions of the lags, where they may be secured, for example, by spot welding, as indicated at 33 (Fig. 2).

Each of the reinforcing channels 39 is formed with a vertical outer end wall portion 34, preferably formed integral with the web portion 3| and depending therefrom (Figs. 2 and 3). The vertical wall 34 serves as a closure for preventing cinders, stones, etc., from entering the cable storage space of the reel through the otherwise open ends of the lags. In order that the lag The dimensions are such that the reinforcing flanges may not be restrained from spreading slightly when under pressure so as to distribute the load over a plurality of lags, the vertical wall portion 34 of the reinforcing channel 30 is preferably not secured to the lag flanges 27 along their adjoining edges. Also, as shown in Figs. 2 and 3, the height of the end wall 34 is slightly less than the flanges 32 of the channel so that sufficient clearance is provided between the rims I4 of the reel heads and the bottom edge of the end Wall to permit a free spreading movement of the lag flanges 21.

One embodiment of the improved means for securing the lagging of the above described type to the reel head rims I4 comprises the following. Referring particularly to Figs. 1 to 3, inclusive, the web portion 26 of each of the lags 25 at its left end (Fig. 2) is provided with an integral arm 3! extending inwardly over the end wall 34 of the filler 3B and the outer edge of the associated head rim I 4 and terminating in an out-turned flange or lip 38. Encircling the lag lips 38 are a plurality of arcuate shaped lag retaining metal strips 39, which in the present embodiment comprise four strips, each strip retaining a predetermined number of lags on the reel head. Each strip at one end is struck outwardly from the plane of the strip a distance substantially equal to the thickness of the metal, as indicated at 40, and opposite ends of the strips which overlap (Fig. 3) are provided with slots4l. A similar slot is formed in each of the lag arms 31 adjacent the 1ip38 thereof. In the present embodiment, four of the spokes I5 of the left reel head (Fig. 2) have welded thereto a plate 45 which spans the inner surfaces of the side flanges of the spoke at their outer edges immediately below the rim I4. The particular spokes which carry the plates 45 are spaced 90 apart corresponding to the points of overlapping of the retaining strips 39. Each of the plates 45 is provided with an aperture for receiving a bolt 4'! which in securing the lags to the reel head is passed behind the plate 45 and then through the aperture thereof and the'slots of the lag arm 31 and overlapping strips 39, respectively.

Each of the lags 25 at their opposite ends is formed with a hook shaped arm 50, which like the arm 3'! is formed integral with the web portion 25 and extends inwardly over the end wall 34 of the filler 30 and the outer edge of the associated head rim I4 and terminates in a right angle portion which hooks under the rim as shown in Fig. 2.

To secure the lags 25 to the head rims I4 the reel is preferably mounted on a suitable device whereby it may be freely rotated during the securing of the lags. The first lag 25 is fixed to the pair of head ribs I4 by hooking the arm 55 thereof over the right rim I4 (Fig. 2) and aligning the slot M in the arm 31 at the opposite end with the aperture of one of the spoke plates 45 and then inserting the bolt 41 through the aligned aperture and slot. Successive lags 25 are then mounted on the rims I4 side by side to cover one quarter of the rim peripheries and another bolt 4'! is then inserted through the aligned aperture of the spoke plate 45 and slot of the lag arm 31, which spoke plate and lag arm are spaced 90 from the first spoke plate, and lag arm, respectively. Thereafter, a retaining strip 39 is mounted in position outside of the series of lag lips 38 with the bolts 41 extending through the slots at opposite ends of the strip.

It will be apparent that the lags 25 between the first and last one of each group, which are bolted to the spokes l5, will be retained in position on the reel heads by the out-turned lips 38 of the arms 31 integral with the lags. The positioning of successive groups of lags 25 and their retaining strips 39 is continued around the heads until the entire rim peripheries have been covered, thereby completely enclosing the cable storage space of the reel. Nuts are then threaded onto the outer ends of the bolts 4! and this completes the effective securing of the lags to the reel. The removal of the lags from the reel it will be obvious may be easily effected.

' Referring now to Figs. 5, 6 and '7 which illustrate an alternative embodiment of the improved reel lag and securing'means therefor, lags 5! similar to the lags 25, previously described, are employed, except that the arm 31 thereof which terminates in an out-turned lip 38, is formed to terminate in an out-turned hook 52 (Fig. 5). The reel head with Which the lag hook 52 is associated is equipped with a plurality of spaced lmobbed studs 53 which project angularly from the reel head intermediate the inner channel member l3 and the rim M. The studs 53 in the particular reel structure illustrated are suitably secured in and welded to the web portions of certain of the spokes l5 spaced, for instance, 45 apart so that a group of lags are positioned on the rim it between each pair of studs. Each of the studs inside the head thereof may be provided with a tapered peripheral slot 54 (Fig. 3) in its periphery into which a wire band or rope 55 may be wedged. I

To secure the lags 5! to the head rims it the reel may be mounted in the manner described in connection with the previously described embodiment and the end of the wire rope 55 is then secured to one of the studs 53 by tying it to and wedging it into the tapered slot thereof. A plurality of lags 5i comprising a group, are mounted side by side on the rims l4, in the manner described hereinbefore, to cover one-eighth of the rim peripheries, the first lag being positioned adjacent the stud to which the end of the wire rope is secured. The wire rope is then entered into the successive hooks 52 of the group of lags, drawn tightly around the following stud and wedged into the slot thereof, and thereafter entered into the hooks of the following group of lags mounted in position, drawn tightly around and wedged into the slot of the next stud and thus continuing around the head, the rope being applied under tension at each group of lags, until the entire series of hooks 52 have been encircled by the single rope, and finally tying the free end thereof to the first stud. The cable storage space of the reel is now completely enclosed by a plurality of groups of lags each group being individually retained in position on the peripheries of the rims M in an effective manner. An expeditious removal of the lags from the reel may be effected by merely reversing the above described operations of securing the lags in position.

In Fig. 7 is shown another embodiment of lagging which may be similar to the lagging described hereinbefore, except that the side arms or flanges 21 thereof are designed to interlock as indicated at to. This is effected by providing one of the flanges 21 at its bottom edge with an open bead 8!, which preferably may be less open than the beads indicated on the lagging hereinbefore described, for freely receiving the opposite flange 2? of the adjacent lag which is a plain flange without a bead at its lower edge. To further increase the strength of the channel type lags and their resistance to impact stresses, particularly intermediate their reinforced ends, the web portion 26 of the lag may be formed with a longitudinally extending reinforcing embossment or rib 62. Either type of lagging may be used on the reel and either one may be secured thereto by one or the other of the described embodiments of securing means.

The above described types of lagging and the several embodiments of means for securing the lagging upon reel heads permits the lags to be readily and effectively secured to the reel and easily removed therefrom; Furthermore, due to the particular arrangement of the lagging and securing means upon the reel, the reelafter being lagged may be laid on either of its endfaces or rolled during handling with other reels without damage to the securing means.

Although in the described embodiments of lag securing means the hooked shaped arm 50 is disclosed for securing one end of the lags to the reel rim, it is to be understood that both ends of the lags may be secured in position by being equipped with one or the other of the securing means associated with the other ends of the lags.

It is to be understood that the invention is not limited to the specific embodiments thereof herein illustrated and described except insofar as is defined by the appended claims.
