18 Claims.

This invention relates to lagging for reels used for storing and transporting heavy material,

such as lead covered cable, particularly to lagging provided with means whereby it may be secured upon such reels.

Objects of the present invention are the provision of an improved construction for reel lagging having a low weight consistent with the required structural strength and simple and practical securing means whereby it may be readily andefiectively secured to reels and easily removed therefrom.

In accordance with the above objects, the invention in-one embodiment thereof comprises a plurality of segmental shaped sheet metal lags for enclosing a metal reel which includes annular head rims upon which the lags are placed side by side. Each lag comprises a plurality of integral channel-like formations terminating in 20 radially extending end arms, the formations having welded thereto reinforcing side walls extending from the outer peripheral channel walls inwardly toward the outer surfaces of inner walls interconnecting and extending from the side arms of the channel formations, the latter walls bearing upon the head rims. The lags are provided with means adjacent the inner edges of the head rims to prevent substantial longitudinal movement of the lags on the reel. Formed in. the opposite side edges of each of the channel side arms and the end arms adjacent the outer surfaces of the interconnecting walls and the inner edges of the reinforcing side walls of the lags and a filler or sealing lag are slots for the reception of a 35 retaining member which encircles the rims under tension for securing the lagging upon the reel.

Means secured to eachof the head rims at diametrically opposite points serves to effectively preventthe accidental displacement of the mem- 40 her out of the slots.

Other objects and advantages of this invention will more fully appear from the following detailed description, taken in connection with the accompanying drawings, in which:

Fig. 1 is a view in side elevation of a metal cable reel provided with the improved lagging and means for seeming the lagging to the reel according to one embodiment of the invention;

Fig. ,8 is a further modifiedform of lagging and means for securing lagging upon a .reel,.and

Fig. 9 is a fragmentary vertical section taken on the line 9-9 of Fig. 8'.

Referring now to the drawings, and particularly to Figs. 1 and 2, one form of lagging em-' bodying the invention is illustrated, for example, in conjunction with acable reel comprisinga pair of spaced heads lainterconnected by a drum [I (Fig. l.) for holdinga leadcovered cable i2, (Figs. .2 -and l) orother heavy material that may be wound thereon. The cable reel itself may beof any suitable construction,although a welded allmetal constructionis preferred. In the construction illustrated, the heads each comprisean outer annular rim it concentric with the drum H and a plurality of corrugated plates of segmental shape welded together to forman annular head plate 55 and welded at its inner and outer peripheries'to the drum ll and outer annular rim M, respectively.

One form of lagging embodying the invention comprises .a plurality of segmental shapedlags it (Figs. v2 and 4) of uniform size and construction andsufficient in number so that whenplaced side by side on the rims Hi and across the widthof the reel, as shown in Figs. 1 and 2, a covering or enclosure is provided for the cable storage space of the reel except for a peripheral space which is less than the covering provided by one of the lags it which space is closed by a filler or sealing lag ll, which will be described presently.

Each lag 16 preferably comprises aplurality of integral channel-like formations 88 formed from a single sheet of metal with radially extending relatively short arms H9 at each end. Welded at their inner sides to the edges of the channel-like formations 58 at. each sidethereof is a reinforcing side wall member 2| which extends from one end to the other of the lag to tie the channel formations l8 and end arms is together to form a rigid structure. The wall-members 2| extend from the outer peripheral edges of the channel web walls inwardly to a predetermined distance from the outer surfaces of walls 22 (Figs. 2 and 3) interconnecting the channel formations I8 for a purpose which will be referred to presently. The lag I6 is further strengthened intermediate the side walls 2! by a member 23 which is T- shaped in cross-section, the member being welded to the spaced inner surfaces of the walls 22 and also to end walls 2 3 (Fig. 5) from which the end arms I?) extend radially. Each end of the lag is further. strengthened by an inverted irregular shapedv member 25 (Fig. 5) U-shaped in crosssection' and arranged opposite the member 23 and welded along all of its edges to the surfaces of the adjacent channel formation it and the end arm l9 and the end wall 2 extending between the arm and the channel formation. Struckout from the walls 22 interconnecting the channel formations it of the lag l6 adjacent the side walls 2! and arranged to extend over the inner edges of the head rims M are tabs 26 which serve to effectively prevent substantial longitudinal movement of the lags on the reel.

One embodiment of the improved means for securing the lagging of the above described type to the reel head rims i4 comprises the following. At each side of the lag Hi the opposite side edges of the side arms of the channel formations l8 and the end arms K9 are slotted, as indicated at 28 (Fig. 3), in the space provided between the outer surfaces of the walls 22 and 2d interconnecting each of the channel formations-and the end arms and the inner edges of the side walls 2| for-the reception of steel retaining tapes or bands 29 which encircle the rims l4 and tie the lags under tension to the reel heads iii. The dimensions of the slots 28 relative to that of the bands29 are such that the bands may be freely entered into slots. To insure that the bands 29 will not accidentally move out of the slots 28.

during movement and transportation of the reel, each reel head NJ has bolted to the inner periph cry of its rim M at substantially opposite points a pair of L-shaped tape retaining clips 36. The clips are formed with an arm 3! which extends over the outer edge of head rim M and the band 29, thus preventing outward movement of the band from its lag retaining position in the slots 28.

To secure the lags IE to the head rims It the reel is preferably mounted on a suitable device whereby it may be freely rotated during the securing of the lags. The first lag i6 is fixed to the pair of head rims Hi by aligning the apertures provided at opposite sides of the lag, for the reception of the bolts used to retain the clips 33 in band retaining position, with the Eorresponding apertures in the head rims, also provided for the clip holding bolts; It is tobe understood that each of the lags i6 is provided with similar apertures although in the completed enclosure for the reel only two substantially opposite lags have the band retaining .clips 3i! attached thereto. Thereafter bolts are entered in the aligned apertures and nuts are threaded onto the inner ends of the bolts. If found necessary additional clips 38 may be employed.

A temporary tie member or band may be suitably attached to the first secured lag i6 intermediate the head rims M drawn over the outer periphery thereof and sufficient tension maintained in the band to hold the following lags as they are placedin abutting relation around the "70 peripheries of the head rims M as the reel is rotated. When a requisite member of lags 16 has been placed in position to completely enclose the cable storage space of. the reel, except for the peripheral space to be filled in by the sealing lag 5 I! the temporary band is drawn up tightly and suitably retained. The peripheral rim surfaces to be engaged by the lag ll serves to provide suitable spaces for sealing the ends 'of the retaining bands 29. The permanent tie member or band 29 is then inserted in the series of slots 28 provided in each of the lags H6 at each side thereof and when the bands have been completely extended around the two series of slots they are drawn up tightly under a desired tension and a sealing or tying member 32 (Fig. 4) is attached to the overlapping ends of each band extending across the peripheral rim surfaces to be engaged by the opposite ends of the lag H to maintain the applied tension, thus effectively securing the lags I6 to the reel. Thereafter the temporary tie member is released and removed from the reel.

The sealing lag H (Figs. 4 and 6), previously mentioned, which is used to fill in the space not occupied by the lags it comprises a single channel formation '35 reinforced and strengthened in a manner similar to the lags l6 and provided with slots 36 at each side for the entrance of the retaining bands 29, the slots being similar tothe slots 28 of the lags 96 except that the slots 36 at one side, the side thereof which is first entered in the space between the first and last of the lags it mounted on the reel are twice as deep as the slots 36 at the opposite side and the slots 28 of thelags it. To complete the enclosing of the reel the sealing lag H is slid into position in the space left between the first and last lags l6, previously mounted on the reel, the side of the lag l1 having the deepest slots 38 being first moved into position between the lags 16 across the head rims 'M from right to left ,as viewed in Fig. 2 and the tensioned retaining band '29 along with the sealing member 32 at the left side of the head rim is raised 01f the rim sufficiently to permit the band slots 36 of the lag. To lock the lag I! in position to prevent longitudinal movement thereof on the reel it is bolted at one side thereof as indicated by bolt apertures 3'! (Fig.6) to the head rim. The band retaining clips 30 are then bolted to each head rim M at diametrically opposite sides which completes the enclosing of the reel.

In Fig. 7 there is shown a modified form of the means shown in detail in Fig. 3 for securing the lagging upon the reel wherein each wall 40 interconnecting spaced channel formations 4i of each lag 42 are formed at their outer sides with integral upturned short lips 43 extending across the space between side arms of each channel formation. The lips 43 are in line with opposite side wall members 44 of the lags, the inner edges of the side Wall members being spaced a predetermined distance from the upper edges of the lips 43. Side edges of the side arms of each channel formation M are slotted, as indicated at 45, the slot extending between the outer surface of the wall ti] and the inner edge of the side wall member A l and for a suitable distance inwardly. Thus a steel retaining tape or band 46 may be entered through the continuous slot provided between the opposed'edges: of the side wall member 44 and the upturned lips 3 and dropped onto the upper surfaces of the walls 40 and behind the inner surfaces of the lips 43. After the bands ii; are in position behind the series of lips l3'at each side of the reel they are drawn up tightly under a desired tension and their ends sealed 'or tied in a manner similar to that described hereinbefore in connection with the other embodiment of securing means. parent that in the construction shown in Fig. 7 the bands 46 will be effectively prevented from moving out of the slots 45 without the use of clips similar to the clips 30 of Fig. 3 or other retaining members by means of the lips 43 formed integral with the lags.

Figs. 8 and 9 illustrate a still further embodiment of lagging and means for securing the lagging upon a reel, the lagging comprising a series of lags 50 and a filler lag 5| which may follow the general formation and construction of the lags l6 and Il shown in Figs. 1 to 6, inclusive. Outer peripheral curved web walls 52 of each channel formation 53 of the lag 50 are formed with a pair of depressions or embossments 54 p which extend across the entire width of the walls 52 and are spaced a suitable distance from each side of the lag, the series of embossments at each side of the lag being aligned. The filler lag 5| is also formed with embossments 51 in its peripheral curved web wall 58 of its single channel formation 59, which are aligned with the embossments 54 of the lag 50. In each space between adjacent channel formations 53 and 59 of the lags 50 and 5| and centered with the embossments 54 and 5'! is fitted a formed up and welded box-like member 60 having its outer surface in the plane of the outer surface of the embossments 54 and 51 and retained in position by welding to the side arms of the channel formations 53. At opposite ends of each of the lags 50 and 5| between radially extending short arms BI and the adjacent channel formations of the lags and aligned with the embossments 54 and 51 thereof are fitted formed up and welded box-like members 62 which are retained in position by welding. Outer end walls 63 of the boxlike members 62 are formed to abut and lie in the plane of the short end arms 6| of the lags 50 and 5| in order that no appreciable space will occur between the ends of the lags.

In securing the lags 50 and 5| to the reel head rims M the method described in connection with the structure shown in Figs. 1 to 6, inclusive, may be generally employed except that a steel retaining tape or band 64 is entered in each series of aligned embossments 54 and 51 extending around the reel, the bands being drawn up tightly under a desired tension and a sealing or tying member 65 attached to the overlapping ends of each band which effectively secures the lagging to the reel. It will be apparent that the box-like members 6|) and 62 not only serve to support the bands 54 across the spaces between the embossed channel formations 53 and 59 and the short arms 6|, thus providing a continuous supporting surface around the periphery of the lagged reel, but also serve as strengthening or reinforcing means for the lags. In the lag construction of Figs. 8 and 9 employing the box-like members 62 the use of a U-shaped member 25, as in Figs. 1 to- '7, inclusive, is not necessary since the members 62 serve as strengthening members for the ends of the lags. The embossments 54 and 51 not only serve to prevent the securing bands 64 from shifting laterally on the periphery of the lagged reel, but also permit the bands to lie slightly within the periphery of the lagged reel, thereby protecting them from damage during rolling of the filled reel.

For preventing substantial longitudinal movement of the lags 50 on the reel, angle members It will be ap--' B8 are welded to walls '69 interconnecting the channel formations 53, the angle members'being fixed adjacent reinforcing side Wall members 10 and arranged to extend over the inner edges of the reel head rims M.

The reellag'ging and securing means therefor in theseveral embodiments constructed and arranged as above described provides a simple rigid structure having a low Weight consistent with its strength and offering a maximum resistance against impact stresses encountered in normal service of a reel and the several embodiments of securing means permits the lags to be readily and effectively secured to the reel and easily removed therefrom.
