STRIP METAL WINDING BLOCK Filed March 24, 1953 3 Sheets-Sheet 3' Fig. 5 ,//2

IE R Tw Patented Jan. 22, 1935 This invention relates to new and useful improvements in winders and has particular relation to a winder mechanism, for reeling strips of sheet metal stock.

While the means of the present invention is of general application it is particularly useful with an arrangement such as shown in my application Serial Number 659,745, filed March 6, 1933, now Patent Number 1,965,219, dated July 3, 1934 wherein the present winder may be used for rapidly unwinding the metal from the spools and winding it into reels after, the metal has been reduced to the desired gauge, without removing the spools from the mill or delaying the operation of the mill in any way.

An object of the invention is to provide a means for rapidly removing metal from a spool and reeling the metal as it is so removed whereby the spools are released for further use about a mill.

Another object is to provide a winder which may be operated at high speed and with a minimum of manual effort.

Other objects and advantages will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawings wherein a satisfactory embodiment of the invention is shown. However, it will be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the appended claims.

One, Water-town, Conn, assiguor to The American Brass Company, Waterbury, Com, a corporation of Connecticut Application March 24, 1933, Serial No. 662,489

' 12Claims. (01. 242-78) proved machine includes a bed 10 supported by a base 11 of any suitable construction, that shown including vertical webs 12 and 13. Other vertical webs than those numbered 12 and 13 and best shown in Fig. 5, may be arranged in any desired a relation to one another so as to give the desired stability to the machine, and the machine may be anchored or secured in place as by bolts 14 embedded in a floor or concrete block 15.

At spaced points along the bed 10- a pair of lo brackets 16 and 1'1 are mounted and these brackets at their upper portions carry bearings 18 and 19 respectively in which is mounted a shaft 20. Bracket 17 is mounted adjacent one end of the bed 10 while bracket 16 is arranged intermediate the ends of the bed and it will be noted that the shaft 20 extends entirely through bearing 18 and includes a forwardly projecting portion 21 carrying a drum 22 disposed over the forward end portion of the bed 10.

This drum 22 includes hub portions 23 and 24 secured to the shaft extension 21 as by keys 25 and 26 and it will be noted that the key 25 enters a flanged cap 27 secured on the shaft as by nuts 28, and which element 2'7 forms a hand 5 wheel by which the drum may be rotated. From this it will be appreciated that the drum 22 is rigid with the shaft 20 and that when said shaft is rotated the drum will also be rotated. To rotate the drum the shaft 20 is driven as by an an independent electric motor 29 mounted on any suitably located base 30 and this motor directly drives a pulley 31 over which is trained a belt 32 j the latter being also trained over a relatively large pulley as loose on the shaft 20 so as to turn thereon.

Pulley 33 forms an element of a clutch and has its opposite surfaces covered with facings 34 and 35 of frictional material as cork, asbestos or the like, and a clutch element 36 is keyed to the shaft 20 as at 3'1 and cooperates with the frictional surface 34. A second clutch element 38 is splined on shaft 20 as at 39 so as to slide longitudinally thereon but rotates with the shaft, and it is adapted to cooperate with the frictional surface 35 of pulley 33. When clutch element 38 is in its disconnected position as shown in Fig. 2 the motor 29 if operating will simply drive the pulley 33 without imparting any turning movement to the shaft 20 and the drum 22. When clutch element 38 is in connected position or in clutching engagement the pulley'33 is gripped between clutch elements 36 and '38 and these latter being keyed to the shaft any movement of the pulley will be imparted to the 65,

shaft and the drum 22 will be rotated. If desired, the belt 32 may be passed over an idler 40 mounted as in bracket 41 whereby to guide the belt and maintain it under tension and by which tension of the belt may be adjusted. As above suggested, the clutch element 38 is slidable to and from clutching engagement with the pulley 33 and the means for sliding and clutch includes a grooved collar 42 forming part of the clutch elementand into the groove of which extend shoes 43 carried by a yoke 44 mounted on a rod or shaft 45 rotatably supported in bearings 46.

Secured to the outer end of shaft 45 is a downwardly extending arm 47 to the lower free end of which is pivoted at 48 a forwardly extending link or rod 49 in turn connected to a rod 50 as by a turn buckle 51 to provide adjustment. At its forward end rod 50 is pivotally connected at 52 with an upwardly extending arm 53' fixed to a short shaft 54 mounted in a bearing 55. Fixedly secured to the short shaft 54 is a foot piece 56 adapted to be manually depressed to shift clutch element 38 to its disconnected position.

When the clutch element is to be disconnected the free end portion of the foot piece 56 is depressed into the position in which it is shown in Figs. 2 and 8 and this results in a partial turning of the shaft 54 so that arm 53 is rocked forwardly drawing forwardly the links or rods 49 and 50 whereby arm 47 turns shaft 45 to have the yoke 44 move the clutch element 38 to disconnected position. A relatively heavy coil spring 57 is secured at its lower end to an arm 58 secured to the foot piece 56 and at its upper end this spring is anchored to a table or shelf 59 and tends to raise the pedal 56 the purpose of which will later be more fully set forth. A second coil spring 60 is secured at 61 to the rod 49 and has its other end portion secured to a bolt 62 adjustable through a bracket 63 whereby the tension of spring 60 may be varied.

It will be apparent that the springs 57 and 60 normally tend to shift the operating parts so as to bring the clutch element 38 into engagement with the frictional surface 35 of the pulley 33 whereby to push the pulley against the clutch element 36 and clutch the pulley to the shaft 20. Therefore, when the drum 22 is to be rotated the operating parts for the clutch element are simply released to be shifted by the springs 57 and 60 and these springs close or engage the clutch so that the drum will be driven by the motor 29. When rotation of the drum is no longer desired foot piece 56 is depressed against the action of the springs and clutch element 38 moved to disconnected position.

With the foot piece sufficiently depressed a pivoted dog or catch 64 is forced inwardly by a spring pressed plunger 65 and the said dog engages over the upper surface of the foot piece as best shown in Fig. 8. Thislocks the parts with the clutch disengaged permitting the drum 22 to be easily turned by hand to properly position the slot for insertion of the free end of the succeeding strip. After the clutch is disengaged by partial depression of the pedal further downward movement of the foot piece will bring a cone surface 66 on the clutch element into engagement with a similar surface 67 of a housing-like portion 68 whereby a braking effect is obtained and rotation of the shaft will be instantly stopped. To again bring about rotation of the drum it is but necessary to force the dog 64 rearwardly or toward the right in Fig. 8 thereby releasing the The drum 22 is to be operated or rotated to wind or reel strips of sheet metal stock and such stock may be delivered to the winder by any suitable means. As here shown, the stock 89 is delivered to the winder on spools 90 the flanges 91 of which are rotatably supported on rollers 92 mounted in a frame 93 of a carrier 94 including rollers 95 operating in tracks 96. The frame 94 includes upwardly extending arms 97 supporting a roller 98 which prevents the spool 90 moving off the carrier. Drum 22 is provided with two or more slots 99 adapted to receive the end of the stock 89 drawn off the spool 90 as shown at 100 in Figs. 3 and 7. When this has been accomplished the clutch may be engaged whereby to have the motor 29 rotate the drum 20 to wind or reel the stock 89 from the spool 90 onto the drum 22.

An upright 101 is carried by the bed 10 and at its upper end includes a bearing portion 102 through which extends a shaft 103 on which is pivoted a hub portion 104 of a frame 105. This frame includes side portions 106 and 107 connected at their ends as by a strap 108 and connected intermediate therein as by a strap 109. These straps serve as spacing means and in addition the intermediate portions of the sides 106 and 107 of the frame are connected by a pin or rod 110 on which is disposed a roll 111. A flexible element or means 112 here disclosed as a piece of leather belting is connected at its respective ends to the straps 108 and 109 as by bolts 113.

Projecting forwardly from the upright 101 is an arm 114 through which extends a pin 115 to which is connected a hand lever 116 and a cam 117. The side 107 of frame 105 carries a projecting portion 118 adapted to be engaged by the cam 117 whereby the lever 116 may be operated to raise and lower the frame 105 to carry the flexible means 112 toward and from the drum. A pin or other stop 119 may limit downward movement of the cam, and the lever 116 may be manually pressed to have the cam pressed downwardly on the frame 105 through a lug 105a whereby to bring the belt 112 into more or less tight engagement with the metal being reeled onto the drum whereby to tension said metal and also prevent injury to the metal or to the operator that might result if the last end of the strip were allowed to run wild at the completion of the winding operation until the revolution of the block or winding drum was stopped. When an end of a strip has been inserted into one of the slots 99 and during the first few revolutions of the drum it is desirable that the flexible means 112 be pressed into tight engagement with the metal to fully tension it. There may be a guard 143 on the opposite or front side of the drum and extending upwardly from the bed to hold the metal should it tend to unwind on the drum when it is stopped. Its curved surface may be covered with a protecting facing 144. A similar but lower guide or guard is provided on the opposite side of the drum. A guide table or shelf 59 as clearly shown in Fig. 3 is placed in front of the drum.

The sheet metal stock is wound onto the drum 22 in the form of a reel 120. Means are provided for stripping a finished reel from the drum and this means includes a stripper ring 121 normally disposed about one end portion of the drum and having a groove 122 in its outer surface. A pair of spaced bars or projections 123 are secured to the ring 121 as by screws 124 and these bars are are of such thickness as to be received in the grooves and lie substantially flush with the outer surface of the drum and when the metal is being wound on the drum to form thereel 120 the metal is wound over the projections 123.

Bed 11 is slotted in its forward portion as at 126 and a slide 127 is mounted on the bed and includes a depending portion 128 operating through this slot. The bed includes portions 129 providing guideways for the slide 127 and on its forward portion the slide carries a yoke 130 the upper portions of the arms 131 of which each carry a shoe 132 entering into the groove 122 in the stripper'ring 121. Arranged below the bed 11 and between the webs 12 and 13 is a cylinder 133 within which is a piston 134 provided with a piston rod 135 connected at its forward end as by a head 136 with the depending piece 128 of the slide 127. The head and portion 128 are pivotally connected as at 137. Fluid under pressure such as air may be supplied to and exhausted from the cylinder through any suitable means as a pipe 139 and the flow of fluid through this pipe is controlled as by a four way valve 140 located convenient for manipulation by the operator.

In the operation of the device the metal to be reeled is brought to the winder either on a spool mounted on a carrier 94 or otherwise. The stripper ring 121 is in its normal position at the inner end of the drum as best shown in Figs. 1 and 4 and the clutch is disengaged. By manipu lating the leverv 116 the operator has raised the frame to an elevated or out of the way position as suggested by the broken lines in Fig. 3. He draws the end portion of the strip 89 from the spooland inserts the end of the strip into one of the slots 99 in the drum. Handle 116 may be operated to lower the frame 105 to have the flexible means 112 engage the strip and dog 64 may now be shifted to release the foot piece 56 and the springs .57 and 60 will act to engage the clutch to have the motor 29 drive the drum. The lever 116 may be operated to forcefully press the element 112 against the metal as long as desired.

As the drum rotates it will carry the stripper ring 121 with it owing to the presence of the projections 123 in the grooves 125 in the drum. However, the stripper rings and the projections are slidable on the drum and when a reel has been formed the clutch is disengaged and the element 38 may be forced against the surface 67 of the housing 68 to apply a braking effectto the shaft. The dog 64 acts to lock the clutch element 38 in disengaged position and the valve 140 may now be opened to have the piston 134 force the slide 127 forwardly. Since the yoke 130 is carried by the slide the yoke will be carried forwardly and as its shoes 132 are located in the groove 122 of the stripper ring the said ring and its. projections will be carried forwardly. That is, the ring is slid along the drum and strips the reel 120 from or forces it off the drum as suggested in Figs. 6 and 7. The bars 123 in the grooves. not only cause the stripper ring to rotate with the drum, but also prevent entrance of the first layer of thin metal between the drum and the stripper ring during the strippin operation, which would prevent proper operation of the stripping ring.

- When the reel is practically off the drum its inner end is supported by the projections 123 from which it can be drawn by the operator and allowed to diop, according to the present showing, on a gravity conveyor 141 including rollers 142 whereby it will be carried out of the way as to a slitter or any other desirable location. Be-

fore the stripper ring: is operated the frame 105 should be elevated, and after a .reel has been forced off the drum the stripper ring 121 is withdrawn or retracted to its normal position and an end of a new strip may be inserted into one of the slots 99 after which the frame 105 may again be lowered and the clutch again engaged to have the motor drive the drum to wind-the next strip thereon. V

From the foregoing description it will be seen that the present machine may be used to rapidly unwind metal or take off metal from a spool 90 and to form such metal into a reel whereby the spool is released for further use in a mill. Also, it'will be appreciated that the machine may be operated at relatively high speed and that it will form the metal into a'tight-reel, and

that the machine may be conveniently operated with a minimum of manual effort.
