DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIGS. 1 and 2, there is shown a baling press 24 comprising a stationary base platen 26 and an upper movable platen 28 actuated by a ram 30. Mounted in the base platen 26 are a plurality of slotted guide members 32, and mounted in the movable platen 2 8 are a corresponding number of bale tie interlock devices 34 embodying the principles of the present invention. Located between the

platens

26 and 28 is a bale of cotton 36 about which bale ties 38 are adapted to be disposed and secured in a manner to be presently described.

Each bale tie interlock device 34, as shown for example in FIGS. 3 and 4, comprises an elongated body or channel member 40 and an elongated plunger 42.

The body member 40 defines an elongated channel 44 generally U-shaped in cross section having first and second inner side faces 46 and 48 and an inner web face 50. As shown in FIGS. 3-6, a hook plate 52 is removably secured by means of screws 54 to the first inner side face- 46 along the outer longitudinal edge thereof intermediate of the ends of the channel 44. The hook plate 52 is formed with an offset hook portion 56 extending in the direction of the right end of the channel 44, and serves to define first hook means. As shown in FIGS. 3-6 and 1:8, a backup bar 58 is secured by means of screws.60 along the first inner side face 46 between the right end of the channel 44 and. the hook plate 52. The inward end of the backup bar 58 is spaced a short distance from the hook portion 56. A guide bar 62, which may be secured to or formed integrally with the backup bar 58, is provided adjacent the rightendof the channel 44. As shown in FIGS. 3, 4 and 117., a retainer bar 64 is suitably secured to the first inner side face 46 along the outer longitudinal edge thereofbetween the left end of the channel 44 and the hook plate52. A backup bar.66,,which may be secured to or formedintegrally with the retainer-bar.64,extends along the first inner side face 46and terminates short of-the inwardend of the retainerrbar64. The hook portion 56 andthe inner longitudinal edges of the

bars

58, 6 2 and 66 are spacedfromthe inner web face 50to accommodate theplunger 42. As shown for example in FIGS. 5 and 6, a stop member 68 is secured as by screws 70.-to the secondinnersideface .48 adjacentthe outer longitudinal edge thereof intermediate of the endsof-the channel 44. .In addition, .as shown .in FIGS. 3, l7,and ;l8,.thebody-member.40,has suitably secured thereto, as by welding, end flanges 72 which are adapted to be removably connected to the upper movable platen 28 by means of screws 74.

The plunger 42, as shown for example in FIGS. 17 and 18, is generally L-shaped in cross section with horizontal and

vertical leg portions

76 and 78. The horizontal leg portion 76 is slidable along the inner web face 50 and is guided by the adjacent edge ofthe backup bar 58 and the adjacent surface of the guide bar 62. The vertical leg portion 78 is slidable along the second inner side face 48. As shown for example in FIGS. 3, l2 and 20, the leg portion 78 is formed with a longitudinal cutout defining a recessed edge 80, a shoulder 81, and an end stop projection 82 which is engageable with the stop member 68 to limit longitudinal movement of the plunger 42 outwardly of the body member 40. Suitably secured along the recessed edge 80 is a guide rail 84. As shown in FIGS. 7, 8 and 23, the vertical leg portion 78 is also formed with an intermediate L-shaped side pocket 86 in which a hook plate 88 is removably secured by means of screws 90. The hook plate 88 is formed with a hook nose portion 92 extending in the direction of the left end of the channel 44, and serves to define second hook means. In addition, a cam block 94 (FIGS. 3 and is suitably secured to the vertical leg portion 78 adjacent the hook plate 88, and an apertured flange 96 (FIGS. 4 and 18) is suitably secured to the outer end of the plunger 42.

One type of bale tie 38 with which the bale tie interlock device 34 of the present invention is adapted to be used, as shown in FIGS. 1, 5 and 6, comprises an elongated body section 98 with engaging

end sections

100 and 102 formed at the opposite ends thereof. The

engaging end sections

100 and 102 respectively include

loop portions

104 and 106 and

free arm portions

108 and 110. The

loop portions

104 and 106 are oppositely curved (FIG. 6) and are'oppositely inclined (FIG. 5).

When tying a bale of cotton or the like, bale ties 38 are placed in the slotted guide members 32 of the baling press 24, a bale of cottom 36 is placed on the base platen 26 and compressed by the upper platen 28, the ends of the bale ties 38 are inserted in the bale tie interlock devices 34 and interengaged, and the upper platen 26 is elevated permitting the tied bale to be removed.

Each bale tie interlock device 34 operates as follows:

First, the bale tie end section 100 and adjacent body section 98 are pushed into the left end of the channel 44. During initial travel, the loop portion 104 engages the inner end of the plunger 42 and pushes the latter from the position shown in FIG. 3 to the loading position shown in FIG. 4. During this initial travel, the loop portion 104 is guided between the backup bar 66 and the inner side face 48, and is retained in the channel 44 by the retainer bar 64. As the stop projection 82 approaches and engages the stop member 68, the loop portion 104 slides off the inner end of the backup bar 66 and shifts sidewise. During subsequent travel, the end section 100 rides over and is guided by the plunger rail 84 as shown in FIG. 4, and the loop portion 104 is retained in the channel 44 either by the retainer bar 64 or the body portion of the hook plate 52. During final travel, the loop portion 104 snaps over and into engagement with the hook portion 56 as shown in FIGS. 5 and 6.

Next, the bale tie end section 102 and adjacent body section 98 are inserted into the projecting end of the plunger 42, and the loop portion 106 is engaged with the hook portion 92 as shown in FIG. 4. Then, the

plunger 42 is pushed inwardly of the channel 44 to the position shown in FIGS. 11 and 12. The inwardmost position of the plunger 42 may be established, for example, by engagement of the plunger shoulder 81 with the stop member 68, or by engagement of the plunger flange 96 with the end of the body member 40. During initial travel of the plunger 42, the loop portion 106 is guided by the backup bar 58, and is maintained in contact with the inner face of the plunger side pocket 86 by confinement of the adjacent body section 98 between the backup bar 58 and the cam block 94. During final inward travel of the plunger 42, the end section 102 is moved toward (FIGS. 5 and 7) and through (FIGS. 9 and 11) the end section 100 to interengage the same. More specifically, the end section 102 is moved over the portion of the body section 98 near the end section 100, while the portion of the body section 98 near the end section 102 is moved through the end section 100. The

free arm portions

108 and 110 are momentarily spread away from the adjacent portions of the body section 98 (FIG. 10) as the

end sections

100 and 102 are snapped therepast.

After the bale

tie end sections

100 and 102 have been I interengaged as shown in FIGS. 11 and 12, the plunger 42 is moved slightly outwardly from the position shown in FIGS. 11 and 12, and the

end sections

100 and 102 are moved relatively toward each other through the position shown in FIGS. 13 and 14 to the position shown in FIGS. 15 and 16 to thereby form a secure knot. Finally, the upper platen 26 of the baling press 24 is elevated, and the bale tie interlock devices 34 are thus retracted from the knotted bale ties 38 to free the tied bale 36.

In the bale tie interlock device 34, there is only one moving part: the plunger 42. Mere longitudinal movement of the plunger 42 effects interlocking of the ends ofa bale tie, an interlocked bale tie is automatically positioned for separation from the interlock device during retraction of the latter, and return of the plunger 42 to its loading position is effected by insertion of one end of another bale tie in the channel 44. As will be appreciated from the present disclosure, the device 34 is convenient to operate, efficient and reliable in operation, simple and inexpensive to fabricate and assemble, and easy to disassemble as may be required for repairs.

While there has been shown and described a preferred embodiment of the present invention, it will be understood by those skilled in the art that various rearrangements and modifications may be made therein without departing from the spirit and scope of the invention.
