FURBER MACHINE C01VIIPANY,OF NORTH ANDOVER, MASSACHUSETTS, A CORPORA- TION OF MASSACHUSETTS SPINDLE. DRIVE FOR SPINNING FRAMES Appl icati on filed November s, 1928. Serial No. 318,093.
This invention relates to a spindle drive for a spinning frame in which the spindles are driven in groups by bands driven in turn by a common driving drum- I11 such spinning frames it is essential that all of the spindles in the frame shall be driven at the same speed and that the driving force transmitted from the band to each spindle shall be the same in order to produce yarn of the same quality on all of the spindles. Furthermore, it is desirable to provide for reversing the twist in the yarn spun on a given frame whenever it may be required.
The object of the present invention is to provide a drive of this type in whichthe twist may be reversed by reversing the rotation of the driving drum and in which the functioning of the drive upon the various spindles will be precisely the same irrespective of the direction of rotation of the driving drum.
The object of the invention is further to provide a drive of this type in which, irrespective of the direction of rotation? of the driving drum, the spindles shall be driven by the band pulling directly from the drum to the spindles in succession.
The object of the invention isfurther to provide such a drive in which, irrespective of the direction of rotation of the driving drum, means are provided for maintaining the band under a constant tension and with the band pulling directly from the drum to the spindles in succession. i i
The object of the invention is further to provide a construction which may readily be embodied in existing spinning frames, which is of a simple character, and which is readily adapted for producing either a right or lefthand twist.
As the invention relates entirely to the drive and is adaptedto be embodied in vari- .ous types of spinning frames, and as the general construction and operationof such spinning frames arewell known and familiar to those skilled in the art, it is-only necessary here to illustrate and describe, and then only in a very general way. those portionsof one type of spinning frame in which a preferred and illustrative form of the present invention may be embodied.
In the drawings:
Fig. 1 is a top plan view illustrating somewhat diagrammatically a section of a driving drum, a set of four spindles, two at each side, and a drive embodying the invention arranged to produce a twist as indicated by the arrows.
1 Fig. 2 is a side elevation somewhat more in detail of a construction such as illustrated the rails 2 supporting at each side a row of spindles 3 and 4c. The driving drum 5 of the usual type extends longitudinally of the frame midway between the two rows of spindles and is adapted to be driven, in accordance with common practice, in either direction according to the twist in the yarn desired.
The spindles are driven from the driving drum in groups, each group by a single band. Preferably, as illustrated, a group comprises two spindles 3 of the row at one side of the frame and two oppositely disposed spindles 4 of the row at the other side of the frame, so that the band 6 will engage a 90 segment of the whirl of each spindle.
In this invention an idler 7 journalled on a suitable support 8 is provided to en age a loop in the band and take up slack. leans are also provided for mounting this support at either side of the driving drum as may be required by the direction of rotation of the driving drum and in order to secure precisely the same conditions controlling the drive in either case. In the specific construction illustrated for this purpose, a rod 9 is mounted at one side of the drum 5 and extends parallel therewith between the drum and the adjacent row of spindles 3, this rod being carried in suitable brackets 10 in the frames. Similarly point 21 of beginning.
another rod 11 is mounted in a similar position at the other side of the drum parallel therewith and between the drum and the other row of spindles 4. The idler support 8, in the specific construction shown, is in the form of a bell crank lever having a fulcrum bearing 12 adapted to fit over either rod 9 or 11, having its depending arm formed, in
two parts 13 and 14 adjustably connected by 2 ing collars thus to position the idler longitudinally of either rod as desired.
It, now, it .is desired to spin with a twist indicated by the arrows in Fig. 1, the driving drum 5 will be rotated in the direction indicated by the arrows thereon in Figs. 1 and 2.
. The idler support will be placed on the rod from the drum, in this case from thetop of the drum, at a point 21 in a direction opposite to the pull given it by the drum and consequently in-a direction opposite to the rotation of the drum, past the idler 7 and directly to and thence around in succession the group of four spindles, passing first around the spindles 3, then above the drum and around the spindles t. From the last spindle the band passes around the idler 7 in the form of a loop, this'loop standing between the .drum 5 and the spindles 8 to which the band first passed. Thence from the idler 7 the band passes around the drum to the It will thus be seen that the band drives with a pull directly from-the drum to. the spindles in succession.
Now when it is desired to place the opposite twistin the yarn, the direction of rotation of the driving drum 5 is reversed and the idler support is simply shifted over onto the opposite rod-11 with the loop in the band pre The, drive at a point 22 in a direction opposite to the pull jg ven' "it by'the drum and consequently 1n, a: direction opposite ,to the rotation of the drum' past the idler 7; and directly to and thence around in succession the group of four spindles, passing first around the spin dies 4, then above the drum and around the spindles 3. From the last spindle the ban-d passes around the idler 7 in the form of a loop, this loop standing between the drum 5 and the spindles a to which the band iirst passed. Thence from the idler 7 the band passes around the drumto the point 22 of. beginning. Again it will be seen'that the band drives with a pull directly from the drum to the spindles insuccession'.
Thus it will beseen that by providing means for mounting the idler support at either side of the driving drum as desired with the band arranged as thus described, the band will always drive witha pull directly from the drum to the spindles in succession, irrespective of the direction of rotation of the drum. 1 V
The idler 7,-by reason of the weight 18 adjustable along the arm 16,- also provides a means by which it is yieldingly forced against the band, under either condition, to maintain a constant tension therein, and it will be seen that this tension will be the same, it the adjustment is the same, whether the twist be a right-hand twist or a left-hand twist, that is, whether the drum 5 be rotated in one direction or' the other. I
Having thus described theinvention, what is claimed as new, and desired to be secured by Letters Patent, is:
i 1. A spindle drive comprising a driving drum rotatable in.either direction according to the twist desired, a row of spindles at each side of the drum all arranged in groups each of which comprises oppositely disposed spindles, a support for each group having an idler journalled thereon, an endless band for each group passing from the drum in. a direction opposite to the pull given it by the drum directly to and around the spindles oflthe group successively, thence forming a loop between the drum and the spindle to which it first passed, thence passingfrom said'loop around the drum to the point of beginning and means for mounting each support with its idler in and engaging the loop of its corresponding band whereby, irrespective of the direction of rotation of the drum,'each band will always drive with a pull directly from theQdrum to the spindles of its group insuccession. I

3. A spindle drive comprising a driving drum rotatable in either direction according to the twist desired, a row of spindles at each side of the drum all arranged in groups each of which comprises oppositely disposed spindles, a rod at each side of the drum extending parallel therewith between the drum and the adjacent row of spindles, a support for each group having an idler journalled thereon, means for mounting each support on that rod away from which the top of the drum is rotated, an endless-band for each group passing from the top of the drum in a direction opposite to its rotation past the idler of the group and directly to and around the spindles of the group successively, thence past the drum around the said idler and thence to the bottom of the drum and around the drum to the point of beginning, and means for yieldingly forcing each idler against its band to maintain a constant tension therein whereby, irrespective of the direction of rotation U of the drum, each band will always drive under a constant tension and with a pull di rectly from the drum to the spindles of its group in succession.
4. A spindle drive comprising the construction defined in claim 1, together with means for yieldingly forcing each idler against the loop in its hand to maintain a constant tension in its band. v
