- the main cylinder and other driven parts of the spinning frame are driven by suitable means, such as the motor illustrated at 14, through a suitable power take-off mechanism 15.
- Lifter rods, such as illustrated at 16, are provided for raising and lowering the ring rails 17 positioned, respectively, on each side of the spinning frame.
- a ring rail 17 carries spinning rings 18 in openings 19 (FIG. 3) provided therein.
- the driving means A is driven at a predetermined speed by the driving means for the spinning frame from a drive sprocket 20 carried by an intermediate gear 21, such as is normally positioned on a spinning frame and the like.
- the drive sprocket 20' drives a chain 22 which, in turn, drives a compound gear 23.
- the compound gear 23 drives a chain 24, which in turn, drives a sprocket 25.
- the sprocket 25 drives a shaft 26 at constant or a predetermined speed.
- the shaft 26 is mounted in an anti-friction bearing 27 carried in a bracket 28 which has suitable mounting on the inside of the Sampson 10a of the frame 10.
- the motor 14 is mounted adjacent the Sampson 1012 at the other end of the frame.
- the means A includes a gear 29 which is driven at a constant speed by the driving mechanism of the spinning frame through the shaft 26.
- the mechanical means B carried by said ring rail movable out of a position remote from the means A into driving engagement with the means A includes a rack gear 30 having pivotal connection on a stub shaft 31 to a transverse arm 32.
- the arm 32 has a pivotal connection as at 33 with a cross-girt 34 of the spinning frame.
- the arm 32 has connection through a chain 35 with the ring rail 17.
- the chain 35 is connected adjacent the free-end of the arm by an S-hook 36 and is connected by an S-hook 37 to the inside of the ring rail.
- a turn buckle 38 is provided for adjusting the length of the chain 35.
- Means C are provided for lowering the ring rail and such includes a chain 39 which has fixed connection as at 40 with a segmental member 41 carried 'by a bracket 42 mounted on a rocker shaft 43.
- the rocker shaft is provided with a foot pedal 44 on each side of the spinning frame.
- Each foot pedal is carried by a lever arm 45 on one end thereof.
- the other end of each lever arm has fixed connection with the rocker shaft 43 which is mounted for rotation in suitable brackets 46 depending from the lower flange of fixed rail 11.
- a member 47 is spring biased outwardly at the bottom and pivotally mounted on the top of a vertical member 48.
- the latching member 47 forms a part of what is known in the trade as an Auto Stop Ring Rail Latch.
- the means C further includes a sheave 49 which is mounted for rotation on a stub shaft 50 carried between the legs of a bifurcated member 51.
- the member 51 is carried for lateral adjustment in the slot 52 of the leg 53 of a bracket.
- a vertical bracket leg 54 has a vertical slot 55 for vertical adjustment by tightening and loosening the bolts 56 (FIG. 1).
- the bolts 56 secure the bracket to a web portion 11a of the fixed rail 11.
- the chain 39 passes downwardly over the sheave 49 and is secured as at 57 adjacent the free-end of the arm 32.
- the rack gear 30 carries an adjustable stop 58 which is secured for adjustment by a screw 59 passing through the slot 60 in the stop member 58.
- the stop member contacts the microswitch 61 carried by the cross-girt 34 after engagement of the rack gear 30 with the gear 29. This occurs after the ring rail has risen in its traversing motions to its highest point.
- the switch 61 is illustrated in FIG. 1 as being in series with the motor circuit 62 of the motor 14.
- the rack gear has an arcuate portion 30a which initially engages the gear 29.
- the gear is turned in a clockwise direction across the intermediate segment 3% and passes over the terminal portion 300 from whence it becomes disengaged with the gear 29 and falls by gravity in the position shown in FIG. 2.
- transverse, horizontal adjustment of the rack gear 30 is made possible by adjusting the lateral position of the stub shaft 31 in the slot 60 near the free-end of the arm 32.
- the rack gear 30 is eccentrically mounted on the stub shaft 31 and a recessed portion 30d is provided on the rack gear opposite the toothed segment 30b to permit the gear 30 to return by gravity to the position illustrated in FIGS. 2 and 3 after passing the high point 30c of the gear 30.
- the ring rail 17 traverses up and down in an ever ascending path so as to build the yarn package 13 progressively from the lower portion of the spindle upwardly until the spindle is substantially full of yarn.
- the upper portion 30a of the rack gear 30 engages the driven gear 29.
- the drive of the spinning frame, through the gear 29, turns the rack gear 30 in the direction of the arrow in FIG. 2 causing the free-end of the arm 32 to be lowered pulling down the rail 17 by the chain 39 which lowers the lifter rods 16 permitting the rail to be pulled down by the chain 35.
- the stop 58 engages the switch 61 to de-energize the frame driving means 14.
- the rack gear 30 is driven further to its low position by momentum of the driven parts of the spinning frame.
- the latching member 47 engages the pedal 44 to lock the ring rail 17 in lowered position for dofling the yarn packages 13 preparatory to another package building cycle.
- apparatus for bearing down a ring rail which is reciprocated vertically during a yarn building operation including: means driven at a predetermined speed by saiddriving means for said textile strand processing machine; mechanical means carried by said ring rail and movable thereby from a position remote from said means driven at a predetermined speed into driving engagement with said means driven at a predetermined speed when said ring rail reaches a predetermined height during the yarn building operation; and means for lowering the ring rail when said movable means is in engagement with said means driven at a predetermined-speed; whereby bearing down of the ring rail may be automatically accomplished utilizing the driving means for said textile strand processing machine.
- said means includes an eccentrically mounted rack gear having a recessed portion so located thereon as to disengage the rack gear from said means driven at a predetermined speed after the ring rail is lowered a predetermined amount.
- gear means driven at constant speed by said driving means for said textile strand processing machine; an arm carried adjacent one end on said strand processing machine on a pivotal mounting; and a rack gear having a pivotal connection to said arm; means connecting said arm remote from said pivotal mounting to said ring rail for moving said rack gear into driving engagement with said gear means.
