Figure 9 isa View illustrating the naltwist of the band.f f l There is. illustrated a twisting machine gen*- erally indicated by the reference `character lIIJ- consisting ofa pair ofupright standards I I'I2, upon wliich'there is suitably mounted a'table orr platform I3. Upon the underside of the table spaced vinwardly of the standard I2 thereisa bracket I4 extending downwardly in parallel relation to the standard. I I'. The standard "I2 and the bracket I'4 are each provided with aligned bearings rfor revolu'bly.r mounting a shaft I5.v vUponthe shaft I there is secured a pulley I6 and pulley IJ, the former being-ldriven from' a motor ISby-means lof arbeltIS.- lUpon the-tablev I3, above the standard 12a pair of brackets 20 and 2li are mounted, Yextending vertically in parallel spaced relation,each of whichy is prothefytwisting spindles and project beyond the bracket each shaft-terminating in respective hooksr 2li, l 25 and 26. 'Theshaft 2I-is of a length greater thanthe shaft 23,-While the shaft 22 is 'of a ilengthless' than the `shaft' 23, as may be seen in Figure 1.

In order ,that thev shafts' Amay be rotated, the shaft -2I' has a gear 2'I`keyed thereto in mesh with a gear 28 fixed to the shaft 22, this latter gear being ,in mesh with a gear 29, secured upon the shaft '23.' The shaft 22 Iincludes a xed pulley'30-:and a freely rotating pulley 3| arranged infclose parallel relation and aligned with ythe drive pulley I'I. A belt`32 is normally trained about the pulley Il and pulley 33, and may be shifted laterally so as to engage the free pulley jby. actuation ofthe belt shifter' 33 suitably mounted upon the underside of the table I3. The'table is slotted as atf`34, to permit passage of the belt to the pulleys 30 and 3|. l

As may be seen in Figure 3, the shaft 22 rotatesin va'clockwise direction while the shafts 23 rotate in a counter-clockwise direction. 'k i s The table I3 supports 'a trackway 35 extending longitudinally thereof, and as shown in Figure 4,

consists'of a pair ofv spacedparallel rail mem bers 3S upon the` upper edges of which there is secured respective strips 31, of a vwidth `greater than the rails so as'to overhangthe inner faces of the latter.` A tension-block 38 is slidable between the guide rails 36 held therewithin by the strips 3l; Upon the block 38 there is a bracket 39` providedwith a lbearing 40, of any suitable anti-friction type, through which a hooked spindle'v4l is journalled. The hook 42 of the spindle ris directed in the direction ofrthe spindles I--22 and 23. )y

An adjustable stop 43 is employed consisting of a narrow block of a length to t'between the rails 36.V The stop 43 includes studs 414 adapted to fit within suitably spaced kapertures 45 formedx in the table I3. The stop 43 occupies a position rearwardly of the block 38 and when making an adjustment for a desired length of band, the block 38 is slid forwardly and the stop is then moved so that the studs 44 register with the desired apertures 45, the latter being spaced longitudinally7 so as to determine the length of theband.

A slidable pegging block 48, commonly known as the leader, is positioned in advance of the tension block 38 in abutting relation, the blocks 38 and 46 being held yieldingly against the stop A43, and in the present instance, this'is accomplished by means of a strand 41 anchored to the pegging block, passed rearwardly over a pulley 48 suitably mounted at the adjacent end of the table; a weight 4S being secured to the free end of thestrand. Another strand 41 is anchored to the block 38 and also passed rearward over a pulley similar to the one 48. A weight is also secured to the free end of this strand.

The operation of the machine and production of a band will be now described:

Size of the band is determined by the number of strands and the size of the yarn used (which may number from 2s to 60s) and also the number of revolutions wound about the twisting spindles. Ordinarily, twelve or fourteen strands of 8`s or 10s single twist knitting yarns are attached to the hook 24 of spindle 2| and carried to the rear end of the machine where it is passed around hook 42 of spindle 4|, thence to the front of the machine where the thread is passed around the hook 26 of spindle 23. Procedure is then reversed and yarny is carried back around the hook 42 of the spindle 4|, thence forwardly to hook 24 on spindle 2|. This manipulation of the thread is indicated by arrows in Figure 5. y

This completes one revolution.

On larger bands, revolutions are made according to size of band to be produced, and size of yarn used.

After two revolutions are completed, strands of threads are passed between yarn on spindle 2|, thence around hook 24, and out, leaving five or six inches of free end with which to splice' together ends looped around the spindles 2| and 23, after twisting motion has been completed.

Spindle 50 now is inserted in the hole in block 46, being placed between yarn mounted on spindles 2| and 23. The function of this spindle is to separate and prevent yarn from twisting together on first twist and to even the second twist.

Since the belt 32 would be engaged with the free pulley 3| the belt is shifted by lever 33 onto fixed pulley 38, thus imparting rotating motion to spindles 2| and 23 through gears 2T, 2-8 and 29. A twisting motion is thus imparted to the thread and blocks 38 and 46 will commence to move forward on the trackway 35, dueto contraction of the twisted thread.

As twisting motion continues, rotating tension on the strands becomes great enough to cause spindle 4| to rotate automatically, twisting the two separate strands together, thus creating the second twist (see Fig 6). y continues, the spindle 50 will chase the two strands being twisted together toward the twisting spindles 2| and 23. At this point, belt 32 is shifted back on the loose pulley and rotation of the spindles is stopped. Spindle 50 is now removed 4from between the twisted strands. (At this point of manufacture, if the operator so As the second twist` desires he may cut or otherwise sever ends 1l mounted on spindles 2| and 23. Tie bands may be produced by the operation up to this point.)

The loose long end of strands mounted on spindle 2| is now threaded through a bailing needle 5| (see Fig. '7), and in turn is sewed through loops formed on spindles 2| and 23, the loop is then removed from the spindle 23, and drawn up tight to and sewed through the loop formed on the spindle 2|. Needle 5| is now passed through two sections of the strand forming a knot joining the two sections together. However, this leaves a small space 52 (see Fig. 8), that does not have sufficient second twist, or what might be termed a loose or soft end.

In order to eliminate this loose or soft end, the

second twist must be equalized, on the loose end.

This is accomplished by reversing ends, by mounting the end originally mounted on spindles 2| and 23,'now joined together, on the hook of the spindle 4|. The opposite end (originally mounted on hook of spindle 4|), is now connected to hook 24 of spindle 2|. A cone-shaped spindle 50 known as a peg, is inserted between the strands connected to the spindle 4| (see Fig. 9), The machine is started again and spindle 2| (thread being held by peg 50 at the other end) removes some of the twist adjacent the spindle 2| and at the saine time puts in twist on end near spindle 4|. As twist on loose end is being put in peg 5U is chased up second twist toward spindle 2|. The end that was mounted on spindle 2| is removed and is now connected onto the hook 25 of spindle 22. Spindle 4| is held stationary by the right hand and belt 32 is shifted to fixed pulley, then immediately shifted back to loose pulley. Spindle 4| is released, the band removed from the spindles, and is complete with a loop at each end.

Twister bands, spinning bands, spooler bands or card bands are made by identically the same procedure, except that the number of revolutions the strands wound around spindles 2|, 4| and 23 are increased or decreased according to the size in diameter of the bands, or according to the size of yarn used.

The bands made on this machine are superior to the old type known as tie bands in that they will last considerably longer under same circumstances, and will make yarn of an evener twist due to the fact that the bands are made the same length and exert the same tension between the driving' cylinders and the whirls, on the spinning, twisting or spooler machines.

While we have disclosed the invention in detail in the best form known to us, it will, nevertheless, be understood that this is purely exemplary, and ythat Various modifications in the construction, arrangement and combination of parts may be made therein without departing from the spirit of the invention, except as more specifically limited in the appended claims, vidierein:
