Filed May 21, 1953, Seri No. 736,735 3 Claims. 01. 28-21) My invention relates generally to hankers and specifically to cord or rope banking devices.

It is among the objects of my invention to provide a means for making a bank of cord or similar material by forming a group of longitudinal strands and then applying a finishing wrapping latitudinally. 7

It is a further object of my invention to provide an apparatus that will automatically form a hank.

Yet another object of my invention is to provide a banking that is rapid, neat, and accurate.

Another object of my invention is to provide a hanker which will formbanks of cord, rope, line, strands, filaments, wire, and other long, flexible materials which are diflicult or inconvenient to handle unless they are neatly formed into hanks.

Yet another object of my invention is to provide an apparatus that will spin a cord (or similar material) around and onto a pair of hanking brackets, and will then rotate the brackets to spin the cord into a latitudinal wrapping. Y

A still further object of my invention is to provide an apparatus that eliminates labor costs in forming hanks and increases unit production by each operator.

These objects and advantages as well as other objects and advantages'may be achieved by the device shown, by way of illustration of my invention, in the drawings in which:

Figure 1 is a front elevational view of the apparatus;

Figure 2 is a rear elevational view of the apparatus;

Figure 3 is. a side elevational view of the apparatus;

Figure 4 is a side view of a safety cut-off portion of the apparatus, partially activated;

Figure 5 is an electrical control circuit for the apparatus;

Figure 6 is a side view of the safety cut-oft shown in Figure 4, completely activated; and

Figure 7 is a top plan view of the apparatus.v

The banking apparatus, in broadest terms, is a pair of stationary hankingarms around which a cord is longitudinally wrapped'by being fed from a rotating drum. When a sufficient number of longitudinal strands have been Wrapped around the banking arms, the arms begin to rotate axially so that alatitudinal finishing wrap of cord is applied to the hank.

Referring now .to the drawings in detail, my rope hanking apparatus has a table 11. An electric motor 12 is mounted under the table 111. A belt 13 connects the motor 12 to drive the shaft 14. A gear 15 is mounted on each endof the shaft 14. The shaft 14 is mounted at both ends on a housing '16. Immediately above the shaft 14, two short shafts 17 for the hanking arms 18 are mounted, on the housing 16 at each end of the shaft 14. Theshafts' jll each carry a large gear 19 engaged with the gears"15,'15;'whereby the hankin'g arms, 18,, 18 are rotated. The end of one banking arm 18 is cleftto receive and frictionally engage the end of a piece of rope or cord. The one of the hanking arm shafts *17 is connected by a chain 20 to a revolution counter control 21.

A second motor 22 is mounted under the table 11. A belt 23 connects the motor to the shaft 24, which is mounted on the housing 16. This shaft drives a chain 25 which operates a second revolution counter control 26. An electric clutch 61, normally disengaged, is connected to the shaft 24, and when engaged, drives the coaxial shaft 27 which normally freely rides on the shaft 24. Mounted on the shaft 27 is a gear 28 which drives the gear 53.

The housing .16 carries four double support bearings 51, 51, etc. which peripherally support a rotatable drum 52. The drum is joined to or made integral with the large gear 53 and has two tracks 50 for support by the bearings 51. The gear 53 engages a smaller idler gear 54, which in turn engages another gear 55 on the outer shaft 56. The outer shaft 56 normally rides freely on the inner shaft 49. On the end of the inner shaft 49 there is a larger gear 57 (Figures 2, 3, and 7). This gear engages a worm 58 mounted on the shaft 59. The shaft 59 carries a gear 60 which in turn engages the gear 19. Consequently, the motor 12 which operates the hanking arms 18, 18 also drives the drum 52, but only when the normally disengaged clutch 62 engages the outer and inner shafts 49, 56 together.

An electric clutch 61 on the shaft 24 will engage and disengage the motor 22 from exerting its driving force on the gears 28 and 53. Another electric clutch 62. dis engages the motor 12 from exerting its driving force on the gear 53. Still another electric clutch 63 disengages the motor 12 from driving the banking arms 18. An electric brake 64 stops the rotation of the arms 18, 118. The drum 52 carries a cord or rope feeder 65.

A safety cut-off 66 in series with the clutches 61, 62, 63 is provided to prevent damage to the apparatus by jamming of the feeding cord 67 if a knot should develop and prevent the cord from feeding. A plate 68 carried by two bolts 69, 69 is mounted on a bracket 70. Springs 71, 71 carried by the bolts 69, 69 normally urge the plate 68 away from the bracket 70. A pair of normally closed. electroswitches 72, 72 are mounted on the plate 68. When a knot 73 forms on the cord or rope 67, it cannot pass through the hole in the plate 68, and it presses the plate 68 to overcome the springs 71, 71. This moves the plate 68 inwardly and the contact pins 74, 74 engage the bracket they open the power circuit to disengage the clutches 61, 62, 63 thereby stopping the apparatus, until the knotted cord is unknotted and-the pins 74 re.-. stored to normal position. a a l 1 The apparatus is ready, for operation when the clutch. 61, clutch 62, and clutch 63 are disengaged. The brake. 64 is set to hold the apparatus immobile. The end of the cord 67 is passed through the safety cut-off 66, through the cord feed 65, and is engaged with the end of the: arm 18. The starter switch 75 is pressed, which engages the clutch 61. This causes the drum to rotate asthe brake 64 is released. The drum 52 rotates, wrapping the cord 67 into the longitudinal'strands 76 forming the longitudinal portion of the hank. When the counter 26 has counted off a predetermined number'- of strands as" havingbeen wrapped around thehanking arms 18, 18, the clutch 6 1 is disconnected by being 'deenergized by the counter 26 and the drum 52 is brought to a stopat the position shown in Figure 5. The circuit. to the second counter 21 is energized through the solenoid switch 78.

. The second counter 21 closes the circuits to the clutches 62, 68. The drum 52 now moves slowly forward in the direction of the arrow shown on the drum- 52 in Figure 5; this is accomplished by the counter 21 energizing the clutch 62 so that the worm gear 58 slowly turns to wind the drum 52 forward. At the same time, the clutch 63 has been energized, whereby the hanking arms 18, 18

are rapidly rotated as the drum 52 moves slowly forward.

The longitudinal strands 76 are consequently rotated by the arms 18 and draw the cord or rope 67 into transverse windings 77, as the feed 65 moves slowly forward with the drum 52 in timed relation to the more rapid axial rotation of the arms. When a predetermined number of transverse windings 77 have been applied to the longitudinal strands 76 to complete the hank, the counter 21 which has all the while been simultaneously driven by the chain 20, opens the circuits to disengage the clutches 62, 63, thereby disconnecting the drum 52 and the arms 18, 18 respectively from further motion producing drive and further rapid axial motion producing driv'e. At the same time, the brake 64 is applied completely stopping the apparatus. It is well to note at this time that the counter 21 stops with the circuits to the clutches 62 and 63 open. Consequently, in order to start the counter into motion again, at the proper time, it is necessary to close the circuit to these clutches 62, 63 momentarily until the counter 21 again closes these circuits. This is accomplished by the counter 26 in conjunction with the cam 79 and the solenoid switch 78 which closes the open clutch circuits and starts the counter 21 again. The counter 21 then closes the circuits to the clutches 62, 63 and the cycle starts again. When the motion of the counter 21 is suflicient to close the circuit to the clutches 62, 63, the solenoid switch 78 drops oh the cam 79 and the auxiliary circuit is open at the switch 78.

The completed hank is then removed from the arms 18, 18, and a second cycle is started. The next cycle is started by the starter switch 75.

The hanks produced may be cut, and put aside. Or, if desired, they may be permitted to remain together and placed, one after the other, as they are formed, into the hank holder 80. The hank holder 80 is entered through the passage 81 and rotates with the arms 18, 18. The counter 21 operates the gear 15 and is connected to energize the brake 64 to stop the arms 18, 18 at the end of the second part of the cycle (latitudinal wrapping). Since the brake is energized, a time delay switch 82 is included in the circuit which switch is adjustable to open the brake circuit immediately after a sufficient lapse of time to enable the brake 64 to stop the operations.

The control circuit shown in Figure 5 embodies the two counters 21, 26. These are standard items of commerce, being a species of electric switch in which a preselected number of revolutions opens or closes circuits. Thus when the starter switch 75 is operated, the counter 26 commences to move and closes the circuit to the clutch 61. The motors 12 and 22 run continuously. The circuit to the clutch 61 is opened after a preselected number of turns and, the auxiliary circuits to the clutches 62 and 63 are closed through the solenoid switch 78. This starts the counter 21 into motion, closing the primary circuits to the clutches 62 and 63.

When the clutch 61 is engaged, the drum 52 revolves rapidly for longitudinal winding. When the clutch 61 is disengaged and the clutches 62 and 63 are engaged, the drum 52 revolves slowly and the arms 18, 18 revolve rapidly for latitudinal wrapping. At the conclusion of a preselected number of turns, the counter 21 energizes the brake 64 and de-energizes the clutches 62 and 63. The cycle may thereafter be repeated at will.

The foregoing description is intended merely to illustrate an embodiment of my invention. Many changes may be made in the construction, selection, and arrangement of the parts, or the substitution of their known equivalents in form and function, and these are intended tube within the scope of the claims.
