5 claims. (ci. 242-19) This invention relates as indicated to a novel reel struclture, and more particularly to a reel especially adapted has made them relatively clumsy and dicultto handle,

fboth when placing them on the pay-olf reel and during lthe drawing operation when the relatively large mass of Athe rotating reel with its load may attain considerable momentum.

`Reels have been employed arranged with verticalaxes so that the coil of rod may be dropped down over the hub from above. As the size and weight of such coils increases, however, it becomes more and more diflicult Vfor the operator to disengage the coil from the hook of the usual Vlifting crane properly to drop the coil onto the reel.

It is accordingly an important object of my invention to` provide a novel reel adapted mechanically to assist in thedisengagement o f a coil of rod or the, like from a crane lifting hook so that such coil may descend onto the supporting reel into position for subsequent pay-olf quickly.

Another object is to provide av modified crane hook particularly adapted to cooperate with my new reel.

A further object is to provide reel mounting means and associated mechanismv which will be actuated upon imposition of excessive tension` in the rod during a pay-off operation and may accordinglybe utilized to stop the operation until the trouble can bevcorrected.

Other objects of my invention will `appear ,as the de- ;v

scription proceeds. n v l l -To the accomplishment of v,the foregoing andA related ends, ,saidy inventionV then comprises theV features .herein- `after fully described and particularly pointed out in the claims, the following description and the annexed drawing setting forth in detail certain illustrative embodiments of the invention, these being indicative, however, of but -a few of the various ways in which the principle of the invention may be employed.

In said annexed drawing:

Fig. 1 is a top plan view of a reel embodying the principles of my invention;

Fig. 2 is a side elevational view of such reel with its foundation support in section and showing the manner in which the crane hook is employed to deliver a coil of rod to such reel; and

Fig. 3 is a detailv view of the modified crane hook at right angles to the Fig. 2 representation thereof.

Now referring more particularly to such drawing, I provide a stationary reel having a square at steel plate base 1 having downwardly extending anges such as 2 ice 2 tting within a corresponding recess or well 3 in the oor vor foundation, such recess having a wider and deeper extension' 4 at one side. Centrally positioned on and welded to'base plate 1'is a cylindrical steel column 5 carrying a table or stand 6 in turn supporting a tubular elbow 7Y which may, for example, be about 20 inches in diameter and is adapted to receive and guide Athe coil of rod C down over column 5.

Eight radially arranged rollers 8, 9, 10, 11, 12, 13, 14 and 15 are inset in base plate 1 rotatably to support the coil of rod which descends thereon. A plurality of vertically disposed rollers such as 16 closely surround column 5 to prevent frictional engagement of the coil with such central column.

4Tubular elbow 7, the upper end portion of which is inclined at approximately 45 from the vertical, is provided with a slot 17 extending a substantial distance from its upper extremity to its inner end approximately coaxial with column`5. The lower end of such tubular elbow, as shown in Fig. 2, will preferably be of a diameter at least as great as that of such column and vertical roller assembly. Inner parallel side wall members v18 may be welded on each side of such slot to extend the same inwardly of the tubular elbow 7 and such inner slot or well may be terminated by a cross-plate 19. A crane hook 20 adapted to support the coil of rod C for transportationto the reel is modified by welding curved wings 21 and 22 to the respective sides thereof to limit the extent:to which such hook can enter slot 17 as illustrated vin Fig. 2 of the drawing, such slot being wide enough to accommodate the width ofthe hook proper. Accord- .ingly, the operator need merely guide the crane so that the lower portion of hook 20 enters slot 17 with the coil of rod C resting upon the upper inclined surface of elbow 7. When the hook is lthereupon lowered, it will drop into slot 17, slot 17 being long enough to accommodate the tip of the hook when this occurs. Y The wings on the hook prevent the hook from swinging any further toward the reel axis. Coil C, of course, is now free to slide down the elbow onto the reel. 1

. Occasionally the coil of rod may tangle. or some other diiculty arise causing some increase in tension in the rod being withdrawn for passage to a subsequent drawing machine or the like `(not shown), with resultant serious `between the outer lower angle of pit or recess 4 to the angle formed between base plate 1 and the corresponding downwardly extending reinforcing flange 24. It will at once be apparent that if excessive tension is imposed upon `rod being withdrawn from a coil positioned on the reel in a direction generally parallel to a line extending from the axis of such reel to such lever 23, the entire base platform will be bodily shifted from right to left as viewed in Figs. 1 and 2 and will also be correspondingly tilted through the action of lever 23. A limit switch 25 is mounted on a support somewhat spaced from base plate 1 and is held in normally open (or normally closed, as desired) position by cover plate 26 hinged at 27 and normally resting on base plate 1. When such base plate is, however, tilted as above described, this serves to rock cover plate 26 (which is itself a second platform) upwardly about its hinge 27 and thereby actuate limit switch 25 to energize appropriate control means to stop the processing operation at the next station. When the difficulty has been corrected, the base plate is returned to the position illustrated and operations may resume. The limit switch may, for example, be in the circuit of the d rive motor of the wire drawing machine or other means "actin-g to withdraw rod from the reel. It should be spaced a sufficient distance from platform 1 to ensure that flange 24 will not strile it or its support should the platform be so far shifted before effective stoppage of the machine.

The horn or elbow may be boited to the top of the reel column at any desired radial angle, as may be convenient in the shop, andrthisvfeatu're also perni-its the base platform to be turned A90" or 180 when the bearings of rollers 416 become relatively more worn on the side away from lever 23. p

It will be seenfrom theforegoing that I have provided la novel pay-off reel for heavy bundles of rod and the like which is very simple to load despite the heavy weight of such bundles and which is safe and easy to stop inasmuch as there `is relatively little rotating mass in the reel itself and the entire reel is mounted for bodily shifting to actuate control means in the event of a tangle.

Other modes of Aapplying the principle of the invention may be employed, change being made as `regards the details described, provided thefeatures stated in any of the following claims or the equivalent of such be employed. n

I therefore particularly point out and distinctly claim as my invention:

l. A pay-off reel device for a coil of rod comprising a floor well, a square steel base platform across said well resting upon the adjacent'floor, downwardly projecting flanges on the underside of said platform parallel to the side edges thereof and fitting closely -within said Well on three sides, the fourth side of said well being substantially outwardly spaced therefrom, a central vertical column on Vsaid platform, a table Lon said column, alplurality of .vertically disposed rollers rotatably mounted closely about said column to engage the vinner periphery of a coil 'of rod encircling Vthe latter, la plurality of horizontal rollers rotatably mounted on said platform radially of said column to supportV a coil'of rod resting thereon, a -l-arge tubular elbow mounted on said table co-axially of -said column and of va diameter at lits lower end at least as great `as that of said column vand vertical roller assembly, said elbow extending yupwardly and laterally at an angle of approximately 45 .degrees to the vertical, a slot lin the upper side of said elbow extending from the outer end thereof to a point generally co-axial with said column, Avertical side wall members for said slot within said elbow, a vertical cross-plate connecting'said side wall members at`the inner end of said slot, lever means angularly disposed in said well bearing at its lower end against a bottom rangle of said fourth side of said well and at its upper end against the angle between the underside of said base platform and said corresponding downwardly projecting ange, a limit-switch adapted to control the drive means of a wire drawing machine or the like mounted adjacent but spaced from the side edge of said platform toward said lever, and a second platform covering the portion of said well not covered by said base platform with one edge resting on said base platform and its opposite edge 4 hingedly mounted on said floor beyond said well, said second platform normally engaging said limit switch to hold the latter from its normal position, whereby excessive tension on rod being withdrawn from a coil on said reel in a direction generally toward said lever will be effective to drag said platform along said well and to rock the leading edge thereof upwardly through action of said lever to raise said second platform and actuate said limit switch.

2. A reel structure comprising a horizontal base, a central vertical column about which Ia coil of rod is adapted to be placedresting on said base, and an elbow extending upwardly and laterally outwardly from said column and at an angle thereto .to guide a coil over said column, the upper side of said elbow having a slot therein extending from the outer end thereof toward the axis of said column adapted to receive the lower portion vof a hook suspending such coil for loading on said reel. l v

'3. A reel having a vertical central column about which a coil is adapted to be placed, and an angularly disposed upward and laterally outward extension of said column adapted 'to guide such coil thereover, the upper side of said extension having a recess therein adapted to receive a portion lof a coil supporting hook when the latter is lowered to deposit such col thereon.

4. The reel o'f claim 3 wherein said recess extends to vthe outer end of said extension.

5. A pay-offire'el having a horizontal base Vplate and a central vertical column-mounted thereon about which a coil of rod is adapted to be placed, a well `adjacent one side ofsai'd base, lever means disposed diagonally in said well pivotally engaging said base plate adjacent the near side edge thereof with its lower end spacedv outwardly thereof, a limit switch for controlling thedrive means f associated rod processing means" or the like supported in'said well adjacent said near side edge of said base plate, and a platform covering said well with one edge resting onsaid bas'efplateV and its opposite edge hingedly mounted beyond said well, said platform normally engaging said limit switch to hold the latter from its normal position, whereby excessive tension in 'rod being withdrawnv from a coil n said reel ina direction generally toward said lever means will be effective to drag said base plate inlsch direction .to rock said lever means to lift the leadingA edge of'said plate upwardly and said hinged platform ,therewithand thus actuate saidV limit switch.
