WIRE REEL Filed July 10, 1939 Patented Nov. 25, 1941 WIRE REEL Sydney Grimshaw, New Haven, Conn., assignor to The F. B. Shuster Company, New Haven, Conn., a corporation of Connecticut Application July 10, 1939, Serial No. 283,601

7 Claims.

My invention relates to the class of devices which are employed for supporting coils of Wire in a manner to permit such wire to be unwound for various purposes, as an example, for supply to a machine for straightening wire to remove bends, kinks, etc., and an object of my invention, among others, is the production of a reel which may be readily positioned for placing a coil of wire thereon and then arranged to support the coils in various positions to permit the wire to be unwound as required; and a further object of the invention is the production of a structure of this type that shall be particularly rigid and strong and well capable of resisting severe usage to which it is subjected.

One form of a wire reel embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawing, in which- Figure 1 is a view in elevation of my improved wire reel.

Figure 2 is a similar view but looking from a point of View at right angles to the point of View of Fig. 1.

Figure 3 is a top plan view.

Figure 4 is a view in horizontal section on a plane denoted by the dotted line 44 of Fig. 1.

Figure 5 is a view on enlarged scale illustrating the counterbalancing segment and the detent for holding it in position.

Figure 6 is a view in section on a plane denoted by the dotted line 6-5 in Fig. 5.

Figure '7 is a view in section illustrating the mounting of the disk for positioning the wire supporting arms and the guide bars for such arms.

The base comprising the main support for this improved reel is constructed principally from bars of channel or other angle iron forms and is preferably of rectangular shape. It comprises two base bars 8 of channel iron bounding two sides other pair of bars ll of similar construction are 7 secured at their ends in spaced relation at opposite sides of the center and have upstanding flanges 2 for the attachment of posts to support the reel-structure. A tie bar i3 is secured at its opposite ends to the opposite side of the frame from the bars 9, the flange of this tie bar being cut away at its ends to receive the ends of the base bars 8, the balance of said flange being bent downwardly between the base bars to form a support for a detent actuating shaft to be hereinafter described. All of the bars and posts hereinbefore described may be secured together in any suitable manner, as by welding or otherwise.

Reel supporting posts M of channel construction are secured at their lower ends to the flanges E2 of the bars I I and substantially at the lengthwise center of said bars, that is, in the center of the supporting base. These bars are of channel iron with the fiat sides facing each other. A counterbalance is pivotally supported for swinging movement between and at the upper ends of the posts Hi, this counterbalance comprising a segment l5 and a head [6, the latter preferably extending above the upper ends of the posts. A hole is bored into the end of the head l6 and a reel supporting spindle I! is secured within the hole and extends outwardly therefrom as shown in Fig. 7. A seat l8 for the reel structure is secured to said spindle preferably a slight distance from the end of the head 16 and a sleeve I9 is rotatably mounted upon the spindle I! against the seat I 8, said sleeve having a flange 20 preferably removably secured thereto.

A cam disk 2| is rotatably mounted on the spindle said disk having cam slots 22 for the actuation of coil supporting arms 23. These arms are slidably supported upon bars 24 secured at their outer ends to a bar supporting ring 25 and at their inner ends by a collar 26 secured to the sleeve l9, said bars projecting into recesses in said collar and being secured therein. The arms 23 have holes through which the bars 24 extend and the lower ends of the arms are provided with studs 2'! that project in to the cam slots 22, one of these studs 28 extending through the cam disk 2! and being threaded to receive a clamp nut 29, this clamp nut acting to secure'its arm as well as all of the other arms against sliding movement and thereby retaining the cam disk 2| in position. A retaining disk 30 may be secured to the spindle I! to hold the reel structure in place on said spindle.

The segment I5 is of considerable thickness to provide weight to counterbalance that of a coil of wire supported on the arms ,23. A groove 3| is formed in the edge of the segment l5, the bottom of this groove on one side having teeth 32. These teeth extend for substantially one-half the width of the groove, the balance of the groove just described being untoothed. A detent 33 is slidably mount-L ed upon detent supporting rods 34 extending between detent supporting posts 35, these posts having been hereinbefore referred to as secured to the flanges of the tie bars 9. In its holding position the detent 33 is engaged with the teeth 32 of the segment IE but may be freed from said teeth by a sliding movement in which position it will be located in the untoothed part of the groove 3|.

The detent is actuated by a detent actuating arm 36 secured at its upper end to the detent as shown in Fig. 6 and secured at its lower end to a detent actuating shaft 3! rotatably mounted-at its inner end in a block 38 secured to one .of the tie bars 9, the opposite and outer end of" said shaft being rotatably supported by a flange-39 projecting downwardly from thetiebar l3 hereinbefore referred to. A trea-dle lever 40 is secured to the shaft 31 as a means for operating -the detent 33, foot pads 4| located at opposite ends ofthe lever Serving as a'means for operating it, foot pressure upon one pad serving to disengage the detent from the teeth 32 of the segment l5 and pressure upon the other pad serving to engage'said parts. A I

When it'is desired to load the reel by placing a coil of wire upon the arms 23 one of the pads 4| is pressed downwardly thereby disengaging the detent 33 from the segment l5; flhe reel may now be tipped to the position shown in dotted line in Fig. 1, and a coil of wire having been placedthereon the reel is tipped backwardly to its fo'rmer position and it is here noted that this operative position of the reel may be in a vertical position as shown in Fig. 1, or in any other angular position between said verticaland' a horizontal position, the teeth 32 on the segment l'5'e'nabling' engagement of the detent 33 therewith to hold the reel in any of these desired positions.

Thecam" plate or disk'Zi maybe rotated inde pendently of the other parts of the 'reel'and for adjustment of the wire supporting arms as' by means of a handle '42 projecting from one side of the carn platel V In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, togetherwith the device which I now consider to represent the best embodiment thereof; but I desire to haveit understood that the device shown is only illustrative and that the invention maybe carried out by othermeans and applied to uses other'than those above set out.
