Each front carrier shuttle 426 has a forwardly facing platform 427 for mounting the base of a front carrier 20F. Each shuttle platform 427 has a rearwardly projecting segment of an arcuate slide tang 428.
Each slide tang 428 terminates in an enlarged diameter keeper flange 429. A slide tang 428 and keeper flange 429 have a length less than the spacing between any two or adjacent first table arcuate slots 327. The radially inner side of each shuttle platform 427 carries a shuttle drive block 430.
Each drive block 430 has two exteriorly opening actuator slots 431. As shown, the actuator slots 431 are oriented radially outwardly toward the rotational axis of a front bobbin 21 F.
A circular shuttle slide track indicated at 432 is carried on the front side of the first table 121. The slide track 432 has a set of arcuate segments, one for each carrier shuttle 426, with an effective radius less than the spacing between a pair of or adjacent first table arcuate slots 327. As shown, the slide track 432 is formed by an inner roller series 433 and an outer roller series 434 mounted on the front side of the first table 121. Each segment of the slide track 432 consists of a set of four inner rollers 433 cooperating with a set of four outer rollers 434. A shuttle platform 427 is secured in a mounted position by positive engagement of a slide tang keeper flange 429 between and with the opposed slide rollers series 433 and 434.
A circular actuator cam track indicated at 435 is carried on the front side of the first table 121 radially inwardly of the sets of opposed inner and outer slide rollers 433 and 434 forming the segments of the shuttle slide track 432. The path of the cam track 435 follows a constant outer diameter broken by a set of inwardly directed V's 436, one for each carrier shuttle 426. The apex of each cam track V 436 is positioned radially inwardly of the inner end of an arcuate slot 327 in the first table 121.

Referring to Figures 14 and 15, a shuttle drive assembly 437 may have a clevis bracket 438 mounted on the second table 122, as by bolts 439, extending toward the first table 121. An actuator post 440 extends through the clevis bracket 438, toward the first table 121, and is attached to the second table 122, as by a bolt 441. The actuator post 440 provides for an articulated mounting of dual symmetrical and laterally projecting drive arms 442.

In Figure 11, the counter-clockwise rotating front carrier shuttles 426 are between the clockwise rotating first table arcuate slots 327. The rear strands 24R have been alternately moved to the inner and outer ends of the arcuate slots 327 by the strand guiding swing arm eyelet 346. The lead shuttle drive arms 442(L) are being moved by the actuator cam track V's 436 so that the lead actuator dogs 445(L) are moving out of engagement with the lead shuttle drive block slots 431(L) and the moving strands 24R at the inner ends of the arcuate slots 327 will pass between each shuttle platform 427 and each shuttle drive assembly 437. The trailing actuator dogs 445 (T) carried by the trailing shuttle drive arm 442 (T) are in driving engagement with the trailing shuttle drive block slots 431 (T).
In Figure 12, the moving strand 24R atthe inner end of an arcuate slot 327 is between the drive arm actuator dogs 445 of a shuttle drive assembly 437 and passing by radially inwadly of a shuttle platform 427. The drive arm actuator dogs 445 carried by the drive arms 442 are in driving engagementwith all of the shuttle drive block slots 431.
In Figure 13, a trailing shuttle drive are 442(T) has been moved by an actuator cam track V 436 so that a trailing actuator dog 445 (T) is out of engagement with a trailing shuttle drive block slot 431(T) and the moving strand 24R at the inner end of an arcuate slot 327 may soon pass behind a shuttle platform 427; for movement by a strand guiding swing arm eyelet 346 to the outer end of an arcuate slot 327.

a second chain means connecting said third sprocket with said fifth sprocket whereby said third sprocket is rotated in a second direction during rotation of said first table in the opposite direction;
a sixth sprocket positioned around said stationary shaft and aligned with said fourth sprocket and coupled to said second table; and,
a third chain means connecting said fourth sprocket with said sixth sprocket whereby said fourth sprocket, coupled to said third sprocket, and said second table are rotated in a second direction during rotation of said first table in the opposite direction.
15. In a braiding machine having a set of rear carriers for a strand supply bobbin mounted on the rear side of a first table for rotation in one direction, the strands from a set of supply bobbins on said rear carriers passing through a set of peripheral and radially arcuate slots in said first table, a second table in front of said first table, a central axis stationary shaft for rotatable mounting of said first and second tables thereon, a drive mechanism for rotating said first and second tables in opposite directions, and an apparatus for mounting and driving a set of front carriers for a strand supply bobbin around the front side of said first table, said apparatus comprising::
a shuttle for each said front carrier, each said shuttle having a forwardly facing platform for mounting the base of a front carrier and a rearwardly projecting segment of an arcuate slide tang having a length less than the spacing between any two of said first table arcuate slots, the radially inner side of each shuttle platform carrying a shuttle drive block having two exteriorly opening actuator slots;
a circular shuttle mounting track carried on the front side of said first table and having arcuate segments extending between any two of said first table arcuate slots and engaging said shuttle slide tangs;;
a circular actuator cam track carried to the front side of said first table radially inwardly of said shuttle mounting track, said cam track following a constant diameter broken by a set of inwardly directed V's, the apex of each said cam track V being positioned radially inwardly of the inner end of one of said first table arcuate slots; and,
a shuttle drive assembly for each said front carrier mounted on the periphery of the rear side of said second table and having two symmetrical and articulated drive arms mounted on and projecting laterally from a single actuator post, each said drive arm being in confined engagement with said actuator cam track on said first table and carrying an actuator dog for articulated movement into and out of engagement with one of each said two shuttle drive block actuator slots.
16. A braiding machine substantially as herein described with reference to the accompanying drawings.
