TAKE-UP MACHINE Filed May 20, 1926 2 Sheets-Sheet 2 Patented Apr. 8, 1930 UNITED STATES PATENT OFFICE FRANK H. SLEEPER, OF WORCESTER, AND WILLIAM H. BLOUN T, F WEST BROOKFIELD, MASSACHUSETTS, ASSIGNORS TO SLEEPER & HARTLEY, INC., OF WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS TAKE-UP MACHINE Application led May 20, 1926. Serial No. 110,531.

rlhe present invention relates to take-up machines, and contemplates a machine particularly adapted to wind heavy eXible material, such as armored cable or metallic tubing, into coils or bundles which may be readily handled.

One object of the invention is to provide a machine of this class having twin reels, with associated driving and clutching mechanism whereby either reel may be driven while the other remains idle. This arrangement permits an operator to start winding on the emptyreel while he removes a coil or bundle from the other reel; thus the machine that l5 delivers the finished product to our improved take-up machine may be operated continuousl yA further obj ect of the invention is to provide a traversing motion that is simple and positive and can be readily controlled. The traversing motion for both reels is obtained from a common shaft and thus the speed of the traverse is always the same for both reels. Furthermore, the drive for the traversing motion is so arranged that the speed of traverse may be readily adjusted.

The above and further advantages of the invention will hereinafter more readily appear, reference being had to the accompanying drawings, in which:

Like reference characters refer to like parts in the different figures.

Referring first to Figs. 1 and 2, the machine generally comprises a pair of spaced frame portions 1, 1, held together by a plurality of cross members 2. One frame 1 carries a bracket 3, which serves as a base for a driving motor 4, it being obvious that any other suitable source of power could be substituted for this motor. On the motor shaft is a pinion gear 5, in mesh with a gear 6 mounted on a shaft 7, which also carries a worm 8. The shaft 7 is suitably journalled in an extension 9 which forms part of a cas- ,ing 10, within which the worm is enclosed, as

shown in Fig. 5.

Referring now to Fig. 5, the worm 8 meshes with a worm wheel 11, which has a hub por tion 11a, loosely mounted on a sleeve 12. The sleeve 12 is fastened, as by means of a set screw 13, to a shaft 14, which is journalled at 15 in the frame 1. The sleeve 12 has a disk 16 formed integrally therewith, and between this disk 16 and the web of worm wheel 11 a layer 17 of frictional material is interposed. The disk 16 and wheel 11 are pressed together by a spring 18 surrounding sleeve 12, the spring extending between the hub portion 11'r1 and a collar 19 screwed onto the sleeve 12; thus providing means for adjusting the tension of the spring and the degree of frictional engagement.

The above arrangement provides a compact reduction gearing together1 with a frictional drive for the shaft 14 for a purpose to be hereinafter described. The shaft 14 eX- tends between the frames 1, and as shown in Fig. 3, carries a gear 20 in mesh with a gear 21, which is rotatably mounted on a stud 22 that projects from the frame l. The gear 21 meshes with a large gear 23, and the gear 20 also meshes with a large gear 24, so that the gears 23 and 24 are driven at substantially the same rate of speed, but in opposite directions of rotation. Referring again to Fig. 1, the gears 23 and 24 are freely mounted on long sleeves 25 and 26, which extend between the frames 1, and are rotatably supported in journals 27 and 28 provided in the frames. The gears 23 and 24 are held from endwise displacement on the sleeves 25 and 26 by the journals 27 on one side, and by small collars 29 on the other side, said collars 29 being secured to the sleeves 25 and 26.

The sleeves 25 and 26 extend beyond the left hand frame portion 1 (Fig. 1) and reels, which are generally designated by the numerals 30 and 31, are fastened to the sleeves at this point. The reels 30 and 31 abut the journals 27 and endwise movement of the sleeves 25 and 26 with the reels is prevented by collars 32 and 33 secured to the sleeves beyond the journals 28 by set screws 34. In order to clutch and unclutch either sleeve 25 or 26 from the gears 23 and 24, respectively, clutch teeth 35 are formed on the hubs of gears 23 and 24, while members 37 and 38 provide complementary clutch teeth 36.

As best shown in Fig. 6, pins 39 extend through the members 37 and 38, these pins being movable in longitudinal slots 40 in the sleeves 25 and 26 and passing through shifting rods 41 and 42, into which they are tightly iitted. This construction fastens the clutch members 37 and 38 to the sleeves 25 and 26, and yet allows said members to be shifted longitudinally on the sleeves by the rods 41 and 42 to engage and disengage the teeth 35 and 36. The shifting rods 41 and 42 extend outwardly beyond the sleeves and have head portions 43 and 44 for manual operation. Spring pressed balls 45 are carried by the clutch members 37 and 38, the balls 45 being adapted to fit in one of two depressions 46, 47 that are provided in each of the sleeves 25 and 26, and thus serve to maintain the parts in position.

The reels 30 and 31 are identical in construction, and a description of one will therefore do for both, the lower reel 31 being shown in elevation in Fig. 1, while the upper reel 30 is shown partly in section. Each reel comprises an inside flange 48 provided on a hub portion 49 which is secured to either sleeve 25 or 26. Each flange 48 has radial slots 50, Fig. 2, for a purpose to be hereinafter described, and the hub 49 provides longitudinal ribs 51. These ribs 51 interlock with longitudinal ribs 52 extending from a flange 53, which provides a hub 54 secured to the sleeve 25 by a nut 55. Removal of the nut 55 permits the flange 53 to be withdrawn from the sleeve, whereupon a completed coil may be removed from the reel.

Referring now to Figs. 1, 2 and 4, the shaft 14 carries a pinion 56 in mesh with a gear 57 mountedon astud 58, the position of which is adjustable by means of a slot 58a provided in the housing 10. The stud 58 carries a pinion 59 inmesh with a gear 60 on a shaft 61, which extends across the machine between the frames 1. With this arrangement of gearing, it is obvious that the speed of the shaft 61 is considerably less than the speed of the shaft`14 which drives the reels, and that the ratio between the reduction gears may be readily changed in order to vary the speed of the shaft 61, all of the gears 56, 57, 59 and 60 being accessible from the end of the machine.

The shaft 61 carries a cam 62 loosely mounted thereon and the cam 62 provides a face 63 having a helical form. The hub 62a of the cam 62 provides an end surface having a projecting dog 64 which is adapted to be received in any one of a series of notches 65 provided on the end of a sleeve 66, slidably keyed on the shaft 61. See Fig. 4. The sleeve 66 is normally pressed toward the cam 62 by means of a spring 67 surrounding the shaft 61 between the end of the sleeve 66 and a collar 68 fast on the shaft 61. A lever 69, pivoted on the frame at 70 provides a yoke 71 embracing the sleeve 66, and carries inwardly projecting pins 71a, freely engaging in a groove 66a on the outer periphery of sleeve 66, as best shown in Fig. 4, whereby the sleeve 66 may be moved longitudinally on the shaft 61 against the spring 67 to disengage the dog 64 from a notch 65. Vhen the sleeve 66 is so retracted the cam 62 is free to turn on the shaft 61 for a purpose to be hereinafter described.

A bar 72 slidably mounted in guides 73 on the frames 1, 1 carries at one end a pair of spaced parallel guide members 74, and it is evident from Fig. 1 that these guide members 74 are adapted to lead the material to be coiled to either reel 30 or 31. As best shown in Figs. 3 and 4, the bar 72 has connected thereto the forked end 75 of a lever 76 pivotally supported at its other end on a pin 77 carried by a iXed bracket 78. The lever 76 carries a roller 79 intermediate its ends, which roller 79 is held in engagement with the helical face 63 of the cam 62 by means of a spring 8O connected at one end to a frame 1 and at the other end to the bar 72.

As previously pointed out, the spring 67 normally maintains the dog 64 in engagement with a notch 65, so that rotation of the sleeve 66 causes rotation of the cam 62, which in turn imparts a reciprocatory movement to the bar 72 through the roller 79. Therefore, rotation of the shaft 61 will result in a slow traversing movement of the guides 74, and material will be wound back and forth on whichever reel is being driven. In Fig. 1 the upper reel 30 is shown as being driven by engagement of the clutch parts 35 and 36, while the lower reel 31 has been rendered inoperative by pushing in'the head 44 to disengage the clutch parts 35 and 36. The clutching members 37 and 38 are adapted to be held in either an engaged or disengaged position by means of the spring pressed balls 45 coacting with the depressions 46 and 47, as shown in Fig. 6.

When the material has been fully wound on the upper reel 30, the operator can quickly stop rotation of this reel by pushing in the head 43, thereby disengaging the clutch parts 35 and 36. At the same time the lower reel 31 can be started'by pulling out the head 44 and after the material has been severed, its free end can be passed between the guide members 74 below the bar 72 and inserted in one of the notches 50 of the ange 48 of the lower reel. The material will then immediately begin to wind on the lower reel 31 with the same traversing movement, which will give the operator opportunity to remove the completed coil, or bundle, from the upper reel 30 after taking oif the outside iiange 53 When starting a new coil on either reel or 31 it is always possible to bring the guide members 74 in position to begin laying the material at the same point on a reel, by moving the lever 69 to disengage the dog 64 from the particular notch 65 in which it is received. The cam 62 is then free to turn on the shaft 61, and the pressure exerted on the cam face 63 by the spring 8O acting through the lever 7 6 and roller 79 is sufficient to always return the cam 62 to the position shown in Fig. 1.

Therefore, upon releasing the lever 69, the

cam 62 is clutched to the shaft 61 in position to resume the traversing movement of the bar 72 with the guides 74 at the eXtreme left hand position with respect to either reel, as shown in Fig. 1.

When the material starts to wind on a reel, the speed of the shaft 14 is substantially the same as the positively driven worm wheel l1, but as the diameter of the bundle increases while the speed of the delivery of the 4material remains constant, the frictional material 17 permits a certain amount of slippage between shaft 14 and the worm wheel 1l. This slippage obviously prevents the material being subjected to too great a tensile strain as it is wound. Since both the Winding and traversing motions are obtained from the shaft 14, each revolution of a reel is accompanied by the same amount of traverse, while the rate of traverse can be readily varied by changing the ratio between the reduction gearing 56, 57, 59 and 60, as previously pointed out.
