3 Claims. 1 l

The invention herein disclosed relates to reels for handling coils of strip stockand for automatically feeding the stripfrom these coils into power presses, forming and shaping machines,

and the like.

Special objects of the invention are to facilitate the loading of these reels with the heavy coil stockwhich they handle and to properly support and control the feeding of such stock. I

I Other important objects of the invention are to control the unwinding of the coil material, to prevent the coil from springing open to too great an extent, and on the other hand, to unwind at a proper rate to prevent binding or dragging of the outer convolutions on the body of the coil.

Further special objects of the invention are to enable adjustments to be quickly and easily made to fit the reel to the particular machine it may be feeding and to accomplish this and the foregoing at reasonable cost in a simple, practical, structural form.

Other desirable `objects attained by the invention are set forth or will appear in the course of the following specification.

The drawings accompanying and forming part of the specification illustrate a present commercial embodiment ofthe invention. Structure, however, may be modified and changed, all within the true intent and broad scope of the invention as hereinafter deiined and claimed.

Fig. 1 in the drawings is a top plan view of one of the new reels; I

Fig. 2 is a side elevation of the same;

Fig. 3 is a broken side elevation on a larger scale, of the adjustable starting and stopping base portion showing particularly the means for vertical adjustment of the reel;

. Figs. 6 and l are broken sectional views on lines 6-"6 and 'I4-fl, respectively, of Fig. 3.

` In the embodiment ofthe invention shown the coill stock' is supported in fiat, horizontal relation on a disc Orturntable 'l carried by a hub 8 rotatably engaged on the upper end of a stationary vertical shaft or spindle 9.

The plate 'I` may be of large diameter to support rolls of large size, and it is therefore shown as braced by radially extending rods I8 secured 'in the sides of the hub by set screws I I and carrying at their outer ends the blocks or rests I2 for the outer, peripheral portions of the plate or disc.

A spring tensioned clamp I3, Fig. 4, operates as a brake on the central portion of the disc to control the coil unwinding movement and to prevent coasting.

Upstanding arms I4, projecting up through slots I5 in the disc are adjustably secured at I 6 on the radial rods I 0 to provide a centering core for the coil laid on the table.

Rotation is imparted to the hub and hence to the turntable structure described by means of a sprocket chain Il running from a gear IIB on the shaft of motor I 9 to a gear 20 on the hub.

A thrust bearing 2| capable of supporting the turntable and its load is shown in Fig. 4 interposed between the lower end of the hub 8 and the stationary head or collar 22 which is iixed on `the upper portion of the post or column 9.

The stationary head or collar 22 carries a series of radially projecting rods or arms 23. Sleeves 24 are adjustably bolted on the outer ends of these radial arms at 26 and these sleeves carry upright posts 25 adjustably secured in vertical relation by bolts 66.

The upper ends of posts 25 have brackets 21 adjustably secured thereto at 28 and these brackets have attached to them the upstanding arcuate guard flange or rim 29.

This guard flange, as shown in Fig. 1, is open at the front of the machine to leave a gap at 30 for the strip passing off the turntable to the press or other machine being fed.

The motor is shown carried by a stationary bracket 3| secured at 32, Fig. 2, in vertically adjustable relation on the column 9. This` mounting of the motor enables accurate line-up of the drive gearing from the motor to the rotary hub of the turntable.

Control of the motor is effected by a feeler or follower shown in the form of a rod 33 extending in over the table and having a downwardly projected, inner end 34 engageable inside the outer convolution of the unwinding stock. This feeler lever is shown pivoted on a horizontal axis, at 35, at its outer end, Fig. 3, so that it may be swung upwardly out of the way of the stock, and as pivoted on a vertical axis, at 36, so that it may swing inwardly to close the motor circuit, or outwardly to open that circuit.

The controlling switch 31 for the motor may be a normally-open microswitch having a circuit closing control lever 38 engageable by a stud 39 dependent from the pivotally supported base portion 40 of the control lever.

The switch actuating pin 39 is shown as adjustably secured by fastenings `4| in an arcuate slot 42 in the base portion of the lever, said slot having a center corresponding to the center of rotation 36, enabling the switch actuating pin to be set in different angular relations, permitting the lever to trip the switch in different zones of travel and hence to be effective to control feeding of stock oif coils of different diameter.

In its up anddown: swinging movements about the horizontal center 35, the triplever isV guided and positioned on the base plate by tting in between the upstanding, spaced, parallel pins 43'.,

The disc or table 'l is shown as slotted in wardly from opposite edges at 44, Fig. 1, to admit and permit the release of thechainV or` thev like which may be used in lowering a coil:y of stock. from a hoist down onto the table. To brace the separated portions of the table these slots may be bridged by brackets 45 arched downwardly to clear any hoisting chain that may be used with the coils.

Additionally, the open ended. slots 44 enable. binding wire or other fastenings that may be wrapped about the coil, to be easily removed.

To afford a maximumv range of adjustment, the switch andcontrol lever are shown supported on, a bracket 46 mounted on top of a post 411 adjustably clamped in thef split end- 48 of a ba-r y49 having its opposite end split and clamped at over one of the posts 2li-which. carry the guard ring 29.

Lateral swinging adjustments of the bar 49 on the supporting posty 25 enable the control lever and switch to beV swung outwardly or inwardly through a wide angle, and: vertical adjustments at 4-8 and 5U permit the control lever and switch to be raised and lowered to best cooperate with stock of different width.

Vertical adjustments of theV reel to the feed.- ing-in level of different machinesvare readily effected in the machine illustrated by a nut 5I on: the lower, screw threaded sleeve portion 52 of the center post or pedestal 9, this portion ofthe post being guided for verticalmovement in the socket 59.v in the supporting base 54. Fig. 5.

The post is held against turning in the base by screws 55 extending into= a key groove 56.

lThe nut 5I bearing on top of the base 54 may be turned by a lever inserted in sockets 51 in the side of the nut, to raise or lower the post.

Set screws 59 hold the screw sleeve 52 in ad,- justed' position on .the post 9.

A split supporting clamp 60 is vshown releasably andr adjustably secured by screws 6| above the screw sleeve 5.2, to carryr the main load after vertical adjustments have been made.

What is claimed is:

1. A stock reel of the character disclosed'cornprising` a substantially horizontal turntable for supporting a coil of stock on edge, means for rotating said turntable to` unwind a coil of stock supported thereon, a circular guard supported in stationary relation in position for limiting the expansion of a coil ofv stock supported onsaid turntable, a follower supported at the outside: of said guard and having a leverage portion reaching over the top of said guard into posi-tion for engagement by the outer convolution of a coil of stock on the turntable, control. means operable by said follower and a horizontal pivotal mounting for said follower enabling the same to be swung vertically up out ofl position over said turntable.
