Application November 2, 1955, Serial No. 544,402

1 Claim. (Cl. 242-1102) This invention relates to improvements in windng or reeling devices and is particularly directed to an improved and novel winding spool for use in winding or coiling wire and similar materials. i

A primary object of this invention is to provide a winding spool, onto and from which coled wire and the like material may be moved in coil form.

Another primary object of this invention is to provide a winding spool which can be easily and readily attached to -a power means', such as the pulley on the power takeoff of a tractor, for the purpose of winding wire into coils or reels and for unwindng coiled or reeled wire and the like materials.

Another important object of this invention is to provide a windng spool, which includes a detachable end wall on one end of a mandrel, which is radially inwardly collapsible so that the coled wire may be passed over the end of the mandrel, associated with the detachable end wall, when the mandrel is' collapsed.

Another important object of this invention is to provide an end wall, which is fiiedly associated with one end of the mandrel and which supports the mandrel in its winding position 'and in its collapsed position, and which carries a drive means for rotating the spool to wind or unwind the wire.

Another object of this invention is to provide a device for winding or coiling wire and the like flexible material in a manner so as to obviate the need for using a core and so that the coiled wire may -be easily stored in compact bundles and may be easily and quickly replaced on the spool for unwinding purposes.

The foregoing and ancillary objects are obtained by this invention, the preferred embodiment of which is set forth in the following description and llustrated in the accompanying drawings, wherein:

Fig. 1 is a longitudinal, vertical, sectional view of the winding spool and is taken substantially along line l -l of Fig. 2, with parts broken away and others depicted in section.

Fig. 2 is an end elevational View of the wnding spool;

Fig. 3 is a front elevational view thereof, showing the same in its winding or unwinding position, and,

Fig. 4 is an elevational View, similar to Fig. 3, with the winding spool shown in its collapsed position.

While one embodiment of the invention is illustrated in the above referred to drawings, it is to be understood that they are merely for the purpose of illustration and that various changes in Construction may be resorted to in the course of manufacture in order that the invention may be utilized to the best advantage according to circumstances which may arise, without in any manner departing from the spirit and intention of the device, which is to be limited only in accordance with the appended claim. And while there is stated the primary field of utility of the invention, it remains obvious' that it may be employed in any other capacity Wherein it may be found applicable.

Referring now more particularly to the accompanyice ing drawings the numeral 10 generally designates the winding spool in its entirety and 12 indicates a mounting or supporting frame, which supports the winding spool. A pillow block 14 is mounted on the frame 12 and secured thereto by *bolts 16. A driving shaft 18 is rotatably oarried by the pillow block and extends laterally therefrom in opposite directions. One end of the shaft is provided with -a pulley or the like (not shown) for attachment to a power means, such as the pulley on the power take-off of a tractor or the like machine. The opposite end of the shaft 18, as shown in Fig. 1, is threaded into the threaded socket 2& of a tubular shaft or sleeve 22. The parts are preferably threaded together for easy detachment but the connection 'may be made by weldng or any other suitable means. The socket 20 is formed in one end of the sleeve and is of a greater diameter than the axial `bore 24 in the sleeve, the socket being counter-bored and providing a stop shoulder to limit the pnojection of the shaft 18 into the sleeve. Suitable means, such as

washers

26 and 28 are provided on opposite sides of the pillow block and circumposed on the s'haft to prevent axial movement of the shaft within the pillow block.

The spool 10 includes an end wall or stationary flange 30, which is disposed adjacent to the frame 12 and which is provided with'a hub 32, through which the shaft 13 extends. The hub 32 is welded or otherwise suitably secured on the shaft 18 so as to be rotated therewith. For example, a setscrew 34 is radially carried by the hub and socketed in the shaft for -securing the ange on the shaft.

A mandrel generally designated by the numeral 36, is carried by the inner side of the flange 30 and is composed of a number of complemental sections or segments, which may be two or more in number. Three of such segments, 38, 40 and 42 are illustrated. Each of the segments is transversely arcuate and the segments are coextentive in length and width and are arranged in a circular formaton so as to provide the cylindrical shape of the mand rel. One of the segments, which is indicated by the numeral 4-2 is stationary, being integral with or fixed to the flange 3i3, as by welding or the like, so that it projects, in a fixed position, laterally from the inner side of the ange, while the

other sections

38 and 40 are hingedly attached to the inner side of the ange 30 with hinges i i and 46.

The sleeve 22 is supported by the fixed section or segment 42, by means of a radially offset projection 43 on the sleeve, which projection is suitably attached, by welding or the like, to the inner face of the mandrel section 42. The mandrel section 38 also supports bearing arm 50, which extends radially inwardly therefrom.

A guide rod 52 is supported by the heating arm St? and s slidably disposed therein and s telescopically and slideably arranged in the bore 24 of the sleeve 22,. The guide rod 52 is provided at its outer end with radially projecting apertured ears 54 and with 'a similar ear se. The ears 54 'lie in the same circle around the guide rod, while the ear 56 is disposed outwardly therefrom, and the ears are spaced apart circumferentially on the guide rod, in accordance with the circle spacing of the mandrel sections. The ears 54 are attached to apertured ears or lugs 58, which are provided on the inner sides of the

sections

38 and 40, by means of links 60. The links 69 provide a pivotal linkage means, whereby upon inwardly sliding movement of the guide red 52 the

sections

38 and 40 are swung radially inwardly about their hinged connections to the fixedly located flange 30. Upon out ward sliding movement of the guide rod 52, the sections are moved radially outwardly and restored to their normal positions, shown in Figs. 2 and 3. Thus, the links translate the axial movement of the guide rod into radi ally swinging movement of the mandrel sections 38 an Means is provided for sliding the, guide rod 52 in the bearing arm and the sleeve 22 and preferably includes an angular bell crank or handle 61, which is pivotally sup,

ported' on the fixed mandrel section 42 by means of a end. The hanclle 61 is pivotally attached by a link 6 6 to an ear 56 on the rod 52.

A detachable end wall or removable flange 68 is-provided to complement the fiange 30 and function as a guide flange therewith for the mandrel 36. The flange 68 is provided with a center hub m that is circumposed about the outer end of the mandreland is detachably secured to the fixed mandrel section 42' by a stud 72. The stud 72' secures the flange 68 in place and is easily removed to permit a speedy andfeasy removal of the flange 68, when it is desired to Collapse the mandrel.

operation When the winding spool is used for Winding and unwinding wire onto and froma coiled form (it` being understood that other exible materials than wire may be handled by the winding spool), the mandrel'

segments

38 and 40 are' in their outer' positions, complementng the fixed segment 42 in providing the cylindrical shape of the mandrel. The mandrel segments 38 and 40' are maintained in" such positions due to the fact that the ears 54 ands58 are slightly over center and therefore forcng an action outwardly on the shaft 52 against the handle 61 and because, medially of the handle 61 the angular projection 74 thereof abuts the fixed mandrel segment 42. The fiange 68 is Secured in place on' the outer end of the mandrel and the winding spool isfin the position,` shown in Fig. 3. In such position, the 'entire spoolwill be rotated by the shaft 18, either in a' clockwise or counter-clockwise direction, depending' upon whether the wire is being wound thereon' or unwound' therefrom.

When the desired amount of wire has been coiled" on the spool, the handle 61 is swung upwardly and inwardly to slide the guide rod 52 into the sleeve 22 and thereby cause the

mandrel segments

38 and 40 to swing inwardly efiectng an inward radial Collapse of the' mane drel. wire slid axially off the mandrel.

When a wire col is to be unwound and distributed, a'

reverse action takes place., The wire coil is placed' on The fiange 68 is then removed and. the coiled From the foregoing specification, it will become apparent that the invention disclosed will adequately accomplish the functions for which it has been designed andin an ecouomical manner, and that its Simplicity, accuracy, and ease of operation are such as to provide a relatively inexpensive device, considerirg what it will accomplish, and that it will find an important place in the art to which it appertains When once placed on the market.

lt is thought that persons skilled in the art to which the inventon relates will be able to obtain a clear unclerstanding of the invention after considering` the description in connection with the drawings. Therefore a more lengthy description is regarded as-unnecessary.

Changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to in actual practice, if desred.
