12 Claims. (Cl. 2432-77)` it carriesV by the automatic resisting actionv presented by the material upon itself. A

A further object is lto provide means for guid ing the material'in its passage on and from the reel. 4 f

These and further objects'will vbe'apparent from the following description, when considered in connection with theaccompanying drawing in which one modication'of the inventionis illustrated. y Y

Referring to the drawing, Figure 1 is a side elevation of the improved reel;

Fig. 2 is an end View partly in section of Fig.1; i Y.

Fig. 3 is a plan view of Fig. 1 shown inl a slightly tilted position., f The improved reel herein illustratedand de` scribed maybe mounted onuany suitable support, for instance on a motor truck 5. This reel is adapted to receive rod, tape or resilient material in other forms particularly for use in connection with conduit duct rodding operations.

Uprights

6 and 7, which may be bolted at their lower extremities to the truck` frame, are 'shown as forming supports for the reel. A shaft 8 is carried by the uprghts and is journaled on antifriction bearings carried by a hub 9. The

uplrights

6 and 7 may be'reinforced by means of braces 10 which are bolted to the uprights land also to the truck frame. The member 'l extends upwardly from the shaft 8 and is provided with bolts 11 which pass through va flange 12 of ring 13 to maintain the Yring in astati'onary position. A series of rollers 14 is provided on a flange 12 which extends about the periphery of the ring 13. These rollers maybe attached in any desired manner to the flange 12. Said rollers are positioned in'such relation to the ends of the arms 15, to be presently described, as to prevent the escape of the rod, tape or other resilient material 16 carried by the reel. The rollers 14 also prevent the material from assuming too small a diameter while being unreeled and also prevent binding between the inner con- K Volution 'of the reeled up resilient material and the guide ring 13. The hub 9 of the reel has a spider mounted thereon. This spider for the purpose of illustration is shown as having `a plurality of sections or arms 15 of substantially U- shaped formation and these arms extend radiali ly from theaxis or hub of the reel. It will be obvious thatother forms of spider may be used, for instancefa spider of'disk form having flanges inturned from itsvperi'pheryy tov form 'abight. One leg of each of the arms 15'is cut off at a suitable distance from the vbight of the 1U, "so as toV provide an opening from one side of` the reel toward `the interior thereof. The armsv 15 are interconnected by means of La bandI 15. The resilient material 16 as it' enters'the reel piles up fromfthe bight ofr the arms towardthe reel axis. To prevent said material vfrom piling uptoward-the aXis beyondthe ycut-off sides of the arms the stationary ring V13 and its rollers are provided, asA previously pointed out. Eachv of the arms' 15 at one extremityfmay be at#r taclied to a flange 17 carried ion one end of the hub, and braces 18, foreach `of the armsv are attached to a flange 19 on the opposite end of .the hub. j n

One end of the resilient material 16 may be suitably attached to theperiphery of thereel at one of its arms, as shown at 20 in Fig. 1. The remainder of said materialis 'piled up fromv the periphery of theV reel toward its axis, with wthe downward end of ,the material extending through the yguidey member 21. This guide member consists of a pair of adjacent plates in which two cooperating rollers are journaled,` and vsaid plates are secured to the sides -of a-,attene'd portion22 of theV ring 13. v n

The resilient material 16` may be wound. or unwound and propelled in either direction by suitable apparatus. This apparatus in the presenti instance isl shown in the formof a tractor mechanism 23,which includes a pair of guided between saidrollers is engaged and-driven Sio ico

by the tractor chain to be wound or unwound from the reel.

The resilient material 16 is Wound or unwound in accordance with the direction of travel of the roller chains of the tractor mechanism.

In the winding operation, the material is guided andpropelled from the tractor'mechanism toward the series of rollers 29, and enters through the opening at one side of the reel and over the external periphery of the stationary ring 13 to the interior of the reel. Vxhen a sufficient amount of material 16 has been wound upon the reel in the manner described, power is disconnected from the tractor mechanism and said material uniiexes and oiers a resilient opposition to the momentum of the reel in one direction. When the power is disconnected from the tractor mechanism at the completion of the unwinding operation of the material 16 from the reel, said material is caused to l'iex more and offers a resisting action to overcome the momentum of the reel in the opposite direction.

. From the foregoing; it is thought that the construction, operation and many advantages of the herein describedA and delineated invention will be apparent to those skilled in the art, without further description. It will be understood that various changes in the size, shape,

` proportion and minor details of construction the terminals and having its. periphery spaced from the ends of said terminals to provide an opening from one side of the reel to the interior thereof through which the resilient material passes, the resilient .material as it enters the reel'bing piled up from the bights of the spider towards the reel shaft and said material as it leaves the re'el being un'piledl in a direction from theV reel shaft towards the bights of the spider. l 2.
