7 Claims, 6 Drawing Figures PATENTED 8W SHEEH m 2 TL E 41 Tics- E STRAND CARRIER FOR BRAIDING MACHINES The present application is a continuation of my copending application Ser. No. 879,294 filed Nov. 24, 1969, now abandoned.

BACKGROUND OF THE INVENTION Conventionally in strand carriers for braiding machines the strand material is wound on bobbins rotatably mounted on the carriers and the bobbins are alternately held against rotation to provide tension in the strand material and released under control of tension members to permit withdrawal of the strand material as the carriers are moved along sinuous paths about a braiding point of the machine to be braided into fabric.

In prior strand carriers, such as disclosed in US. Pat. No. 3,324,757, the bobbin is provided with ratchet teeth for engagement by a pawl or detent for engaging a single tooth of the ratchet, said pawl being moved by spring means into holding engagement with the ratchet teeth on the bobbin. The pawl is released from the bobbin by a tension member which is moved by the strand, against the action of compression springs, from a strand take-up position to the pawl release position. As the pawl is released from the bobbin tension in the strand and the movement of the tension member in the strand take-up direction rotate the bobbin in the strand payoff direction and the length of strand withdrawn from the bobbin is taken up-and tensioned by the tension member, and movement of the tension member in the take-up direction again releases the pawl for engagement with the bobbin ratchet. Since this re-engagement of the pawl with the ratchet very often occurs between a pair of the ratchet teeth the take-up movement of the tension member continues to rotate the bobbin in the strand pay-off direction until a tooth engages the pawl to stop the bobbin movement. When this take-up movement of the tension member is combined with the inertial forces normally tending to rotate the bobbin in the pay-off direction as the carrier moves between inner and outer portions of its sinuous path the ratchet teeth impacts the pawl with sufficient force to damage both the pawl and ratchet teeth.

Also in the carrier of said Pat. No. 3,324,757 the inertial forces developed as the carrier moves in opposite directions between inner'and outer portions of its sinuous path sometimes causes the bobbin to rotate in the reverse or strand rewind direction to again move the tension member to release the pawl from the ratchet. When such reverse movement of the bobbin occurs the force required to overcome the inertia of the bobbin to again rotate it in the strand pay-off direction is transmitted directly to the strand which sometimes causes the strand to break. I

In another prior form of braiding carrier, which is designed to reduce the damage to the bobbin ratchet and detent means and to prevent the bobbin reversing movement, such as that disclosed in US. Pat. No.

3,425,315 the detent is provided with the same number of teeth as the ratchet member associated with the bobbin "to distribute the impact force developed in stopping the bobbin in the pay-off direction. This carrier is also provided with an overrunning clutch which permits rotation of the bobbin in the strand pay-off direction but prevents rotation of the bobbin in the reverse direction. However, while the clutch is effective in stopping the reverse rotation of the bobbin damage continued to the teeth of the ratchet and detent during impact thereof to stop the rotation of the bobbin in the pay-off direction.

In addition to the damage to the bobbin ratchets and detents in the carriers of said Pats. Nos. 3,324,757 and 3,425,315 as above noted the normal range of move ment of the tension members between their detent releasing and strand take-up positions is greatly increased by the excess length of strand inadvertently withdrawn by the tension members until the pay-off movements of the bobbins are stopped by the detents. This causes a fluctuation in the tension applied to the strands by the tension members beyond the desired strand tensioning limits and results in the formation of defective material braided by the machine.

SUMMARY OF THE INVENTION Briefly summarized the invention resides in the provi sion of means for controlling the inadvertent rotation in opposite directions of a strand bobbin of a braiding carrier said controlling means including a first torque type spring having coils normally tending to contract to arrest the rotation of the bobbin in the strand pay-off direction, and a second torque type spring having coils normally tending to contract to arrest the rotation of the bobbin in a direction reverseto the strand pay-off direction. The coils of the first spring are expanded by movement of the strand tension member of the carrier in one direction to permit rotation of the bobbin in the strand pay-off direction and are permitted to contract to arrest bobbin rotation by the movement of the strand tensioning member in the opposite or strand take-up direction. The coils of the second spring are expanded by the rotation of the bobbin in the strand pay-off direction. I

DESCRIPTION of THE PREFERRED EMBODIMENT The strand carrier shown herein is adapted for use in a high speed braiding machine and the instant invention'is particularly directed tomeans in such carrier for controlling thefeeding of wire strand material from a the strand pay-off direction. The means for controlling the rotation of the bobbin in the strand pay-off direction includes a member connected to and rotatable with the bobbin and a first torsion type spring having coils normally tending to contract to grip and hold the rotatable member and bobbin against rotation in the strand pay-off direction and means which is operated by the strand tension member to expand the coils of the first spring to release the bobbin for rotation in the strand pay-off direction. The means for controlling the rotation of the bobbin in the reverse direction comprises a second torsion spring having coils arranged to normally contract to grip and stop the rotation of the rotatable member and bobbin in the reverse direction and to release the member and bobbin during their rotation in the strand pay-off direction.

Referring particularly to FIGS. 1 to 3 of the drawings, the strand carrier includes a foot member which is adapted to be secured, as by screws 11, to one of the horn gear operated foot portions of conventional carriers or similar driving members, indicated diagrammatically at 12 in FIG. 1, which are adapted to operate the carriers along oppositely directed sinuous paths about the braiding point of a braiding machine. A spindle 15 is mounted in fixed position in the foot member 10 (FIG. 5) for rotatably supporting a bobbin 16 for strand material 17 of single or multiple filament steel wire or the like. Also secured in fixed positions in the foot member 10 are posts or standards 20 and 21, a spaced pair of tubular support members 22 and a support rod 25. The upper ends of the posts 20 and 21, support members 22 and support rod 25 are retained against deflection relatively to each other by a bracket 26 which is secured to the posts and support members as by pins 27 (FIG. 1).

In its path from the bobbin 16 to the braiding point of the machine, the strand 17 passes from the bobbin around the post 20, under a grooved roller 30 rotatably mounted on a support member 31 on the foot member 10 and over a grooved roller 32 rotatably mounted on a tension member 33 slidably mounted on the support members 22 and support rod 25. From the roller 32 the strand passes under a grooved roller 35 on the foot member 10 and over a grooved roller 36 on the bracket 26 to the braiding point of the machine. The tension member 33 is adapted to be moved to apply tension to the strand 17 under the control of coil type compression springs 37 mounted on the support members 22 between the tension member and foot member 10, and a compression spring 40 mounted on the support rod 25 between the tension member and an adjustable nut 41 treadably carried on the support rod 25 adjacent the foot member (FIG. 1), in the manner and for purposes set forth in said PaLNo. 3,425,315.

As the carrier moves around the braiding point of the machine, the bobbin 16 is adapted to be held against rotation and to be released for rotation in the strand pay-off direction, the clockwise direction as indicated by the arrow A' in FIG. 2, and to be held against rotation'in a direction reverse'to the strand pay-off direction, the counterclockwise direction as indicated by the arrow B in FIG. 2. The means for holding the bobbin against rotation and for releasing the bobbin for rotation in the strand pay-off direction in accordance with the instant invention includes a member 42 mounted for rotation on the spindle 15, the member 42 having an upper flange portion 45 with upwardly projecting lugs 46 for releasable engagement in slots 47 in the underside of a lower flange 48 of the bobbin,'said slots extending radially of the spindle at opposite sides of the axial center thereof (FIGS. 4 and 5). Extending down- 5 wardly from the flange portion 45 of the member 42 is a bearing portion 50 adapted to be rotatably received in a bore 51 in a bracket 52. Arms 55 extending outwardly of the upper end of the bracket 52 are provided with open ended slots 56 adapted to closely embrace the support members 20 and 21 to hold the bracket against rotation during rotation of the member 42 and bobbin 16 in the manner hereinafter set forth. The member 42 also includes a lower portion 57 which is secured to the lower end of the bearing portion 50 as by screws 60, the lower portion 57 having an upper bore 61 rotatably embracing the spindle l5 and a lower bore 62 rotatably embracing an upwardly extending hub 65 of the foot member 10. The member 42 is main- 20 tween the upper end of the hub 65 of the foot member and a C-ring 63 or the like on the spindle, as shown in FIG. 5.

The bracket 52 has an outer peripheral surface 67 aligned with an outer peripheral surface 70 on portion 57 of the member 42 and the surface 70 is in turn aligned with an outer peripheral surface 71 on thehub 65 of the foot member 10. An upper torque type coil spring 72 is mounted on the peripheral surfaces 67 and 70 of the bracket 52 and, member 42, respectively, between the arms 55 of the bracket and an annular lip 75 on the member 42. A lower torque type coil spring 76 is mounted on the surfaces 70 and 71 on the member 42 and hub 65, respectively, between the annular lip 75 and the foot member 10, which coil spring acts to hold member 42 and the bobbin 16 against rotation in the reverse direction. Member 42 and bobbin 16 could also be held against reverse rotation by other suitable means, such as a unidirectional or one way running clutch mechanism. The spring arrangement illustrated is extremely effective and represents a preferred construction, but effective operation of the bobbin pay-off can also be achieved by other mechanical configurations.

A projecting end 77 of the upper coil of the spring 72 is anchored in a hole 80 in the bracket 52 (FIG. 5) and a projecting end 81 of the lower coil of the spring 72 is anchored in one of a series of notches 84 in a sleeve member 82 positioned for rotative movement between the foot member 10 and arms 55 of the bracket 52 and loosely surrounding the springs 72 and 76 (FIGS. 3 and 4). A spring 83 connected between the sleeve member 82 and the support member 31 tends to bias the sleeve member clockwise as viewed in FIG. 3. The coils of the spring 72 are arranged so that they normally tend to rotate clockwise relatively to the anchored upper end coil during contraction as viewed in FIG. 3, and this tendency of the coils to contract coupled with the clockwise movement of the sleeve member 82 by the spring 83 causes the coils to tightly grip the surface 67 on the bracket 52 and surface 70 on the member 42 to hold the member 42 and bobbin 16 against rotation in the pay-off direction. On the other hand when the sleeve member 82 is rotated in the counterclockwise direction, as hereinafter set forth, the coils of the spring 72 are expanded to release the member 42 and bobbin 16 for rotation in the strand pay-off direction.

tained against axial movement on the spindle 15 be- A projecting end 88 of the lower coil of the spring 76 is anchored in a hole 89 in the hub 65 (FIG. 5) and the coils are arranged so that they normally tend to rotate counterclockwise relatively to the anchored end coil, as viewed in FIG. 4, to contract and grip the surface 70 on the member 42 and the surface 71 on the hub 65 to hold the member 42 and bobbin 16 against movement in the counterclockwise or reverse direction to the strand pay-off direction and to release the member 42 i and bobbin during movement in the strand pay-off direction.

Secured in a recess 87 in the sleeve member 82, as by screws 90, is a plate 91 having a downwardly angled nose portion 92 adapted for engagement by a camming surface 95 formed on the lower end of a finger 96 secured to the tension member 33 (FIGS. 1, 2 and 6). Following each release of the bobbin 16 for movement in the strand pay-off direction by a movement of the sleeve member 82 in the counterclockwise direction the strand 17 is withdrawn from the bobbin and taken up by an upward movement of the tension member 33 to its position of FIG. I under the control of the springs 37 and 40. At this time the finger 96 .is out of engagement with the nose portion 92 on plate 91 and the sleeve member 82 has been moved clockwise to its position of FIG. 3 to cause the coils of the spring 72 to grip the member 42 to hold the member 42 and bobbin 16 against further movement in the strand pay-off direction. Also at this time the coils of the spring 76 are in gripping engagement with the member42 to hold the member and bobbin against rotation in the reverse direction. Thereafter, as the strand withdrawn from the bobbin is used at the braiding point during movement of the carrier thereabout, as above set forth, the tension member 33 is gradually moved downwardly, from its position of FIG. 1, until the finger 96 again engages the nose portion 92 to move the sleeve member 82 counterclockwise to expand the coils of the spring 72 to release the member 42 and bobbin 16 for rotation in the strand pay-off direction to permit withdrawal of a further length of strand from the bobbin,

It will be understood that the improvement specifically shown and described by which the above results are obtained can be changed and modified in various ways without departing from the invention herein disclosed.
