CAGO, ILLINOIS, ASSIGNORS TO WESTERN ELECTRIC COMPANY, INCORPORATED, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK i METHOD OF AND APPARATUS FOR SECURING IN CLOSURE ELEMENTS ON CONTAINERS Application filed August 30, 1930. Serial No. 479,065.

This invention relates to a method of and apparatus for securing inclosure elements on containers, and more particularly to a method of and apparatus for positioning and 5 securing lags on cable reels.

An object of the invention is to provide a simple and efficient method of and apparatus whereby inolosure elements may be secured to containers expeditiously and with a minimum amount of manual labor.

One embodiment of the invention contemplates the provision of a method of and apparatus for securing lags upon a cable reel by means of bands of metal tape, wherein the reel is rolled in place between a pair of jacks or elevators having center plugs adapted to be inserted in the central bore of the reel, the jacks being thereafter operated to elevate the reel from the surface of the floor whereby it is rotatable upon the center plugs. The reel is rotated by means of radially extending arms having gripping members for engaglng the first lag which is temporarily nailed or otherwise secured to the reel heads. The

gripping the ends of metal tapes which are drawn from supply rolls through the rotation of the reel and are applied upon the lags as the latter are inserted in place between the tapes and the rotating reel heads. Means is provided for controlling and indicating the tension under which the metal tapes are applied to the reel. The tape supplying and tension controlling mechanisms are movable to permit removal of a lagged reel by rolling it in the same direction in which it was received in the apparatus. I

A more complete understanding of the invention will be had from the following detailed description when read in conjunction with the accompanying drawings, in which Fig. 1 is a side elevational view,partly in section, of a reel lagging apparatus embody ing the features of the invention;

. Referring now to the drawings, in which like referencenumerals designate the same parts in the several views, it will be observed that the invention is herein illustrated in conjunction with an apparatus for securing lags 8, 8 to a cable reel 10 by means of bands 9, 9 of metal tape or thelike. The reel is rotatably supported between a pair of hydraulic jacks 1111 of any suitable type adapted to elevate the reel from the surface of a floor or platform 12. A tubular shaft 13 (Fig. 3) is rotatably j ournalled in a bearing portion 14; of each of the jacks l1, and slidably carried in each of the tubular shafts is a center plug 15 upon which the reel is rotatably suspended.

A pair of worm gears 17 and 18 are mounted upon each of the tubular shafts 13 on opposite sides of the bearing portion 14, the gear 17 being free to rotate while the gear 18 is keyed to to be rotatable therewith. The worm gears 17 and 18 are arranged to be driven by worms 19 and 20 keyed to vertical shafts 21 and 22, respectively. The shafts 21 and 22 are rotatably journalled at their upper ends in a horizontal plate 24 secured to posts 25, 25

v the bearing portions 14 of the jacks 11. Arms 26 and 27 extending laterally from the bearing portions 14 of the jacks are formed with suitupon-the shaft, the shaft so as able bearings for rotatably supporting the lower ends of the vertical shafts 21 and 22, respectively. I

The vertical shafts 21 are driven through bevel gears 29 and 30 from a horizontal shaft 31 which, in turn, is driven through gears 32 and'33 from an electric motor 34. The vertical shafts 22 are similarly driven through gears 35 and 36 from a horizontal shaft 37 which, in turn, is driven through gears 38 and 39 from an electric motor 40.

The motors 34 and 40 are supported upon the horizontal plate 24, which plate is also formed with suitable bearings 42, 42 (Fig. 2) for the horizontal shafts 31 and 37. From the construction just described, it will be understood that the worm gears 17 and 18 together with the driving mechanism therefor, are supported by the jacks 11 and vertically movable therewith.

A pair of reel driving arms 44-44 are secured at one end to the tubular shafts 18 so as to be rotatable therewith and extend radially along the outer faces of the heads of the reel. The outer ends of these arms project beyond the peripheries of the reel heads and are formed with a groove 45 for interlocking engagement with a hook portion 46 of lag gripping members 47 (Fig. 7 said hook portion being provided with a spring pressed locking plunger 48 for preventing accidental displacement of the lag gripping members with respect to the reel driving arms. The lag gripping members 47 are formed with rectangular slots or pockets 49-49 for receiving the end portions of the first lag 8 which is provisionally secured in place on the reel by nailing or otherwise and are provided with a projecting tape gripping finger 50. The construction is such that during the rotation of the reel, the ends of the metal tapes 9 are firmly gripped or wedged between the side of the first lag 8 and the gripping fingers 50.

Securedat one end to the outer faces of the gears 17 area pair of spaced supportmg arms 52 52 which are rigidly interconnected by cylindrical cross bars 53, 54 and 55.

.A pair of spaced idler rollers 56.-56 are carried upon the cross bar 53 and asecond pair of rollers 5858 are rotatab-ly supported upon the cross bar 54 and are disposed in peripheral alignment with the rollers 56. A pair of grooved guide pulleys or rollers 6060 are rotatably carried by the cross bar and are disposed in peripheral alignment with the rollers 56 and 58.

A pair of rolls or pads 62-62 of the metal tape 9 are rotatably carried upon the end portions of a horizontal shaft 63 supported in brackets 6464 depending from the cross bars 54 and 55. The tape supply pads 62 are held in position upon the shaft 63 by means of spider like retaining plates 66-66 threaded upon the ends of the shafts. Through the rotation of the reel by the driving arms 44 acting through the first lag 8, the metal tapes are drawn from the supply pads 62 over the idler rollers 58, around the grooved rollers and over the idler rollers 56.

In order to insure against breaking of the metal bands and displacement of the lags during transportation of the reel, it is necessary that the metal bands be applied thereto under a definite predetermined tension- For this purpose, mechanism is provided for controlling and indicating the tension of the metal tapes as they are applied to the reel. This mechanism comprises a dynamometer 70 (Fig. 5), or other suitable tension measuring device, which is adjustably connected at oneend to a fixed arm 71 projecting from the bracket 64 and is connected at its opposite end to an adjustable spring pressed brake band 72 arranged around a friction brake drum 74 secured to or formed integral with the guide roller 60. Through the movement of the tape as it is drawn from the supply pad, the roller 60 and brake drum 74 are rotated against the braking pressure of the brake band 72. This braking pressure is reflected in the dynamometer 70, which may be provided with a calibrated scale 7 5 and a cooperating pointer 76 for indicating the tension under whichthe tape is applied to the reel. It will be, obvious that the tension of the tape may be readily varied by merely adjusting the brake; band 7 2.

The rollers 6Q are preferably rubber tired or otherwise constructed to eliminate slippage. betweenthe tape and the roller. In order to. further reduce such slippage, the tapeis passed between a stationary brake shoe 78 and a movable spring pressed brake shoe 79 disposed between the supply pad and the idler roller 58. p The stationary brake shoe 7 8 is secured to the bracket 64, and the movable brake shoe 79 is carried at one end of a lever 80 pivoted intermediate its ends upon a pin 81 mounted in the bracket 64, and pivoted at its opposite end in a bifurcated end portion 83 of a lever 84. The lever 84 is pivoted intermediate its ends upon a pin 85 mounted in the bracket 64 and is connected near its opposite end to one end of a coil spring 87, the opposite end of which is adjustably attached to the bracket arm 71. Thus, it will be understood that the moving tape is pinched'between the brake shoes 7 8 and 79 under the tension of the spring 87, which may be adjusted so as to apply the necessary, amount of. tension on the tape to reduce. to a minimum the slippage between the tape and the roller 60.

The outer end of the lever 84 is disposed. in the path of a pin 88 (Fig. 6). extending from and movable with the pointer76 of the dynamometer 70. As the tension of the tape increases, the pin 88 movesupwardly andupon the tension increasing above a predetermined amount, the pin engages the lever 84 thereby relieving the pressure of they brake shoe 79 to permit suflicient slippage between the tape and'the roller 60to reduce the tension to the required amount.

In order to prevent longitudinal displacement of the, lags, they are each provided with anotch 90 (Fig. 2) at either end thereof leaving shoulders 91 for engaging the internal faces ofthe reel heads. The outer'face of each lag is provided with a pair of transverse tape'receiving grooves 93 which serve to retain the tapes in definite positions and also prevents them from protruding above the surface of the reel. r

In the operation of the above described apparatus, a reel is rolled in place between the jacks 11 and the center plugs 15 are inserted in the central bore thereof. The first lag 8 is nailed or otherwise temporarily secured to the heads of the reel after which the ends of the metal tape 9 are bent inwardly over the under-side of the lag, and the lag gripping members 47 are placed in position upon the ends of the lag and interlocked with the reel driving arms 44. The jacks 11 are then operated in a well known manner to elevate the reel from the surface of the floor sufficiently to permit its rotation upon the center plugs 15. Upon starting the motor 40, the reel driving arms 44 and thereby the reel are rotated in a counter-clockwise direction (Fi 1). The lags are fed by hand or otherwise to the upper surfaces of the tapes and are thus inserted in place between the rotating reel heads and the metal tapes 9 as the latter are withdrawn from the supply pads 62 through the rotation of the reel. A vertical guide plate 95 secured to angle brackets 96 extending from one of the roller supporting arms 52 is arranged to engage one end of the lags as they are advanced with the tapes, whereby the lags are conveniently lo-' cated with respect to the reel heads.

hen the lagging operation has progressed to the position indicated in dotted outline in Fig. 1, the rotation of the reel is discontinued by stopping the motor 40, whereupon the motor 34 is started to elevate the tape and roller supporting arms 52 to the position indicated in dot-ted outline in Fig. 1. Upon the arms 52 arriving at this position, the motor 34 is automatically stopped through the operation of a limit switch 98 connected in the motor operating circuit. This switch is mounted upon a bracket 99 secured to one of the vertical posts and is arranged to be actuated by an actuating arm 190 carried by one of the roller supporting arms 52.

\Vith th reel completely enclosed by the lags, the metal tapes 9 are sealed at 102 (Fig. 1) in any suitable manner to form continuous bands, and it will be understood that during the sealing operation the tapes are maintained under the required predetermined tension which is indicated by the dynamometer in the manner above described. After the'tape sealing operation, the tapes are severed adjacent the seals, the lag gripping members 47 are removed, and the reel is discharged by rolling it in the same direction in which it was received in the apparatus. The roller supporting arms 52 are then lowered through the rotation of the motor 34 in a reverse direction. A limit switch 105 is mounted in the lower end of a supporting leg 106 pivotally carried upon the shaft 63 and is connected in the operating circuit of the motor 34 so as to automatically stop the motor upon its engagement with the floor when the roller supporting arms 52 arrive at their original or starting positions.

It is believed that the advantages of the apparatus of the present invention will be i apparent from the above description. The simple and compact arrangement of the apparatus, the convenient method of feeding the lags, the efficient means for applying the metal bands under a predetermined indicated tension, and the facilities for supplying and removing the reels in straight line progression contribute to provide an apparatus of maximum eiiic1ency and economy.
