ST TES PATENT OFFICE 2' Claims.

My invention relates to reels on which coils of wire, cable and the like are wound, or on which coils may be placed in order to be unwound as used.

5 When wire, or the like, is wound in coils on reels it is often desirable to remove such coils from the reels entirely, without unwinding the coils, but this is done only with considerable difficulty with ordinary types of reels or spools and generally necessitates the complete destruction of the reel or spool or, at least, the prying off of one of the side disks of the reel, rendering the reel unfit for further service. Furthermore, difficulty is often experienced in removing the core of the reel from within the coil of wire or other material when the wire or other material has been tightly wound on the reel.

When a previously wound coil of wire, which is not on a reel, is to be used, it is desirable to place the same on a suitable dispensing or payout reel to keep the coil together and in place and to facilitate the dispensing or paying-out of the wire as it is used. For this purpose it is necessary, not only to have a reel with a core on which the wound coil may easily be slid, but also to provide a reel with an adjustable core to fit coils of various size and to hold the coil securely on the core.

An object of my invention, therefore, is to provide a reel from which the coil of wire, cable or other material may be removed easily and without damage to the reel, and on which a previously wound coil may be placed and securely held for dispensing.

This object I accomplish by forming my reel with a side wheel or disk which is removable from the core and further by making the core itself adjustable and collapsible so that the core can be reduced in size to permit the coil to be slipped off or on the core when one of the side disks is removed.

Another object of my invention is to provide a reel on which coils of various diameters may be wound, or may be placed for unwinding, and 5 this object I attain by so arranging the core that its diameter may be varied by a simple manipulation of the side disks or wheels.

A further object of my invention is to provide a reel on which coils of various widths may be 50 wound, or placed for unwinding, and this object I accomplish by making the distance between the two side disks or wheels, which constitute the sides of the reel, readily adjustable on the core.

A still further object of my invention is to pro- .5-5 vide an adjustable reel of the type above indicated which can be made strong enough for prac tical use with heavy Wire and the like, but which will still be simple in construction and not costly to manufacture.

The manner in which I attain these and inci- 5 dental objects will be apparent from the following description with reference to the accompanying drawing.

In the drawing:

Fig. 1 is an end elevation of the reel, =a por- 10 tion of this figure being shown in section for the purpose of illustrating the construction more clearly;

Fig. 2 is a sectional plan taken on the lines 2-2 of Fig. 1 and looking in the direction indi- 5 cated by the arrows;

Fig. 3 is a sectional plan taken on the line 3-3 of Fig. l and looking in the direction indicated by the arrows; and

Fig. 4 is a fragmentary elevation, partly in 20 section, and drawn to a larger scale showing the means for supporting one of the bars constituting the core in the construction shown in Fig. l.

A dished plate 18 having a peripheral flange l9 and a central hub 20 has a stub-shaft 2i firmly 25 secured in the central hub 28 and is provided with a series of radial bars 22 symmetrically arranged and rigidly secured to the hub 20 and to the flange 19. Each of the bars 22 has a bracket 23 slidably mounted thereon, the bars 22 being 30 bent to conform with the interior of the recessed plate l8, substantially as shown in Figs. 1 and 2. The sliding brackets 23 are arranged to carry perpendicular arms or rods 24, the bottoms of which arms are secured to the brackets in any suitable 3 5 manner, for example, they may be secured on threaded stems 25 formed integral with the brackets as shown in Fig. 4. The arms 24 are thus movable radially towards or away from the central hub 20.

A pair of identical wheel-

like members

26 and 21 constitute the sides of the reel and form the supports for the adjustable core constituted by the arms 24. Each of the wheel-like members comprises a central hub 28, bored to slide on the stub-shaft 2|, a rim 30, preferably made of pipe or tubing, and a series of supporting curved rods 3|. The curved rods 3| correspond in number to the arms 24 and are arranged symmetrically about the hub 28, being rigidly secured to the hub 28 and to the rim 3%] by welding or any other suitable means. These rods 3| are so shaped that when symmetrically arranged they will form with each other a series of curved guideways 32 for accommodating the arms 24, and these guideways are adapted to cause the arms 24 to be moved simultaneously towards or away from the central hubs when the wheels are particularly rotated on the stub-shaft 2|. Slotted-head set screws 29 are provided for the purpose of holding these Wheels rigidly in place on the stub-shaft 2|.

When my reel, made in this manner, is to be assembled for use, the brackets 23 and their attached arms 24 are arranged so that their centers lie in a circle about the hub 20, as shown in Fig, 2. The wheel-like member 26 is then placed on the stub-shaft 2! with an arm 24 in each of the guideways 32, and slid on the stub-shaft until the member 26 is adjacent the dished plate l8. A washer 33 is preferably interposed between the hub 20 of the dished plate and the hub 28 of the wheel-like member 26 to facilitate subsequent turning of the wheel 26 with respect to the dished plate [8. The wheel-like member 26 is rotated until the arms 24 form a core of the desired diameter, whereupon the slotted-head set screw 29 is tightened to retain the Wheel 26 in this position on the stub-shaft 2|. Then the other wheel-like member 21 is placed on the stub-shaft 2| with its guideways in registration with those of the wheel-like member 26 and thus with the arms 24 extending thru its guideways. The wheel-like member 21 is then secured in place by the tightening of the set screw 29. I consider my reel when constructed in this manner particularly suitable for use where large diameter reels are required because of its skeleton construction.

When the Wire or other material has been wound on the reel and it is desired to remove the entire coil, the member 21 is removed from the stub shaft 2| and the slotted-head set screw 29 of the member 26 is loosened and the member 26 is then given a slight turn on the stub shaft 2| so as to cause the arms 24 to be moved slightly towards the center of the reel, and thus relieve all tension on the coil, which may then be readily lifted off.

Similarly when a coil of wire is to be placed on the reel for dispensing, the member 21 is first removed; the set screw 29 of member 26 is loosened and the arms or core rods 24 are moved by the turning of member 26, until these arms lie in a circle slightly smaller in diameter than the interior of the coil. When the coil is placed on these arms and the member 21 is replaced, the arms are then moved outwardly as far as possible by the turning of the

members

26 and 21 so that the arms will hold the coil tightly in place. The set screws 29 in the

members

26 and 21 are then tightened so that these members, and with them the arms 24 will be held in this position.

Obviously modifications might be made in the construction of details of the various parts of my reel without departing from the principles of my invention. This is particularly true in the construction of the wheel-

like members

26 and 21 and also in the mounting for the arms or core rods 24 on the radial bars 22. It is not my intention to restrict the construction of the particular members in my reel or to limit my invention in this regard otherwise then as set forth in the attached claims.
