REEL FOR comm SHEET METAL swans H Filed Aug. 27, 1951 2 smis wpsmw 2 ff" '2 'll'" I 7'TOR/VEX Patented Oct. 28, 1952 UNITED STATES PATENT OFFICE REEL FOR COILING SHEET STRIPS Roland Disler, Detroit, Mich. I Application August 27, 1951,"SerialNo. 2435890 3.0laims. (Cl. 242-48) My machine is especially designed for coiling marginal strips of sheet metal, the strips'being of the kind which are cut off on each side of a sheet as it isproduced ina rolling mill. When done by'hand the coiling requires considerable effort, owing to the resiliency of the metal, such as steel, out-of which the sheets are made. It is to eliminate the need of manual coiling of such strips that I have devised a machine to be operated by power means, such as an electric motor.

I shall now describe my machine Withreference to the. accompanyingdrawings in which:

Fig. l is a vertical sectional view of the machine shown in combination with elements which are indicated only diagrammatically;

Fig. 2 is a side elevational view of the machine;

Fig. 3 is a sectional View on line 3-3 of Fig. 1;

Fig. 4 is a sectional view on line 4-4 of Fig. 1;

Fig. 5 is a diagrammatic illustration in perspective of the reciprocating mechanism for the purpose of fitting a strip of sheet metal to the reel for even distribution of the strip onsaid reel lengthwise thereon.

Similar numerals refer to throughout the several views.

Supported on bearings l0, which are mounted on horizontal bars ll forming a part of the machines framework 12, is a horizontally-disposed shaft l3. Axially keyed to the shaft at one end thereof is a sprocket wheel l4. At the opposite end the shaft supports a reel, generally indicated by numeral I5. The reel comprises a hub, gen erally indicated by numeral IS. The hub includes a circular end plate l1, having a tapered rim Ila, and a spider, generally indicated by numeral l8, said spider being mounted on the same shaft in a spaced relation to said plate H. The spider, being of a smaller diameter than said plate I1, is substantially star-shaped and insimilar parts cludes a plurality of radially-disposed prongs 0r spokes lSa. A plurality of transversely-disposed rods [9 extend from the rim l'la to the tips of prongs 18a, each rod being affixed to a separate prong, as best shown in Fig. 4. The result is the formation of a cage-like hub tapering in diameter from plate I! towards said spider 18, there being a free space |8b between each two prongs. Each individual rod has an integrally connected extension 22 disposed radially from rim 2| of plate I1, all extensions being in the same plane at right angle to said shaft l3. The extensions are afiixed to a circular backing plate 23 which forms a flange or a side of the reel and is either keyed or preferably welded to the shaft, as shown at 24. An opposed flange or plate 25 of .the reel is circular inshapean'd .adjoins the outer'face of the spider I8, but is notattached thereto. The plate has an axial openingto fit removably .over the end-ofshaft l3-andis .secured against displacement bymeans .of anut 25, the shaft being threaded. for that purpose at its end, as shown at 26a.

Axially mounted on shaft l3,:midway its ends, isa worm 2'! meshed with apinion-28. The latter is axially keyed to one endof shaft 29, theother end supportin a wheel 30. vPivotallyaffixed to a pin 3| on the surface .of the wheel, inan eccentric position thereon, is varod 32 which-at its outerwend ispivotally connected to a slidingbar. 33. The bar is supported. in a bearing 34.and is connected to a guide 35 comprising a narrow frame through whicha strip to be wound upon the reel is fed thereto. The guide, as will be seen from the drawings, is adapted to be actuated in a reciprocating movement laterally with respect to the reel or parallel to the shaft l3.

The power for the operation of the reel is supplied by a conventional electric motor, indicated by numeral 36. The rotary speed of the motor is adapted to be modified by a variable speed reducer, identified by numeral 31. In order that the pulling power of the motor upon the reel may be kept below the limit where the strip to be reeled would break, I also employ a device, indicated generally by numeral 38, which permits slippage of the driving element in case the resistance of the driven element has reached a predetermined limit. A shaft 39 in said last device 38 supports a sprocket wheel 40. A chain 4| is employed to convey power from the said wheel 40 to the sprocket wheel I4 on said shaft I3 which supports the reel itself. Numeral 42 indicates bearings for shaft 29.

The operation of the machine is quite obvious.

The slippage device, indicated by numeral 38, is adjusted for the tensile strength of the metal strip which is to be wound on said reel. As this strip is fed to the reel it is evenly distributed thereon by means of the reciprocally moving frame 35 through which the strip is threaded. When a sufiicient quantity of the strip has been wound on the reel the machine. is stopped, nut 26 is unscrewed, and flange 25 is removed from shaft l3. .This will leave the strip rolled upon the reel exposed from one side. Next a wire is slipped into the center of the coiled roll through one of the open spaces 18b in the spider l8 in the direction of plate H, where the wire will be deflected by the bevelled edge of plate ll upwardly and radially outwardly along the inner surface of plate 23. The wire will serve as a means of binding the strands of the rolled strip together before said roll is removed from the reel.

It is obvious that some changes may be made in the structure of the reel without departing from the inventive principle disclosed herein.

What I, therefore, wish to claim is as follows:

1. A power-driven reel as described, the reel comprising a shaft threaded at one end, a plate axially mounted thereon, said plate having a tapered rim, a spider similarly mounted on the shaft in a spaced relation to the plate, the diameter of the spider being smaller than that of the plate, said spider including a plurality of radiallydisposed prongs with open spaces therebetween, a backing flange for said plate, said flange being secured to the shaft for rotation therewith, a plurality of rods extending from the tapered rim of the plate to the outer ends of the prongs of said spider to form a cage-like hub tapering in the direction of said spider, a circular flange abutting the outer surface of the spider, said flange being removably mounted on said shaft, and a nut threaded upon the end of the shaft to retain said last-named flange in place.

-2. A reel as described, the reel comprising a shaft threaded at one end, a disk-like plate axially mounted thereon in a spaced relation to said end of the shaft and having a rim tapered in the direction of said end, a spider similarly mounted on said shaft in a spaced relation to said plate but being of a diameter smaller than that of the plate, said spider being substantially star-shaped and including a plurality of radial spokes defining open spaces therebetween, a circular backing flange for the plate, said flange being welded to the shaft, a plurality of rods each disposed crosswise from the rim of the plate to the outer tip of the respective spoke, the rods with the plate and the spider forming a cage-like hub of the reel tapering in the direction of the spider, said rods having integrally-formed extensions disposed radially and afiixed to the inner face of the backing flange, a circular flange abutting the outer surface of the spider, said flange being removably mounted on the shaft, and a nut threaded upon the end of the shaft to retain the last-named flange in its place.

3. A reel of the kind described and comprising a shaft adapted for rotation, a disk-like plate axially mounted thereon, a substantially circular spider similarly mounted on the shaft and spaced from the plate but being of a smaller diameter than that of the plate and including a plurality of radial prongs with free spaces therebetween, the plate having a rim tapered in the direction of said spider, a plurality of rods spaced from each other and connecting the outer rim of the plate with the tips of the prongs to form a cage-like hub, a flange Welded to the shaft and backing the plate, a removable flange abutting the outer surface of the spider, and a nut to secure the flange in its place on the shaft.
