Application f led January 29, 1926., Serial No.

This invention relates to spinning, douhling and like machines of the flier type having mechanical dotting mechanism in which it is found somewhat diiiicult to prevent the drag washers from being displaced at one time or other during the carrying out of the doliing process. Our present invention consists in the application of means where by The displacement of the washers at all .imes prevented while the same means aliord facilities for retaining and moving the bob bins during certain parts of the dofing process which we now carry out by the employment oi the novel .devicesdiereinaiter explained.

In order that our said invention may be readily understood, we have hereunto appended sheets of drawings illustrative thereof in which l is a front elevation showing the several parts of the machine in their respective positions during the spinning operations.

Fig. 2 is an end elevation of the parts shown by Fig. 1 also in the positions they occupy as shown by said Fig. 1.

Fig. 3 is a similar end elevation to Fig. 2 but shows certain :of the parts adjusted in their respective positions during one of the first stages of the doifing process.

4 is also a similar view to Fig. 3 but shows the next step in the process of dofling and the position that the several parts occupy after .such step has been taken.

Fig. 5 shows certain of the parts 'il-lustrated by Fig. 4 -readjusted ready for carrying out the replacing "of the empty bobbin-s on the spindle.

Fig. 6 shows the several parts readjusted in their respective positions just prior to their readjustment in position for the spinning actions to berecommencedand before the cutting of the several threads is ef fected.

Figs. 7 and 8 are sectional end elevation and plan respectively and show our drag devices drawn to an enlarged scale.

Fig. 9 is a sectional end elevation of the foot-step rail o-fzthe machine and our improved form of toot-step 'bearing for the spindle.

Fig. 10 is a plan of the machines lifter rail and ourd'rag-device with a spindle and a bobbin shown in section and in certain relative positions hereinafter described.

84,6G3, and in Great Britain J'anuary28, 1525.

Fig. 11 is a front elevation of the parts shown by Fig. 10.

Figs. 10 and 11 are drawn to a smaller scale than are Figs. 7, 8 and 9.

A indicates the end frames of the machine, and B the foot-step or supporting rail for the spindles. All the otherrparts shown by the drawings, and which are not hereinafter referred to are of the ordinary and usual formation .and construction.

It may be here observed that the doliing process and many of the movements oi the devices for carrying same into effect to which our present invention relates are well known to those having a knowledge of the spinning industry, so that we have hereinafter only referred to same to such an ex- :tent as would clearly show wherein our .novel devices CllfiBI "from those previously employed for carrying out the removal of the full bobbins (after the spinning operations had proceeded as far :as desired) on the stopping of the machine and the supplying of empty bobbins to take their place prior to the restarting of the machine.

Further the kind of machinery in which our doffing apparatus has to be made use of is that known as flier spinning, doubling, twisting and like frames, wherein the fliers 4* at all times revolve with the spindle 4 upon which they are fixed.

In carrying out our invention we employ a receptacle or holder 2 for the drag washers 3 (see Figs. 7 and 8) on each spindle l of the machine.

This holder 2 is preferably formed of sheet metal by the process of stamping although we are aware that it may be formed by casting or otherwise.

'The holder 2 has a central opening for the spindle 4 to pass through while it has projections 2 formed on it to span the lifter rail5 upon which it is loosely mounted and by which projections it is held against rota- .tion by said lifter rail. 5.

From the base of the holder '2 we have other projections 2 arranged to extend vertically above same so as to hold orretain the drag washers 3 within while said drag washers are arranged to surround the spindles 4: upon which the fliers 4 are fixed. The "ertical projections 2 are situated laterally the spindle and are formed to have their upper ends a slightly lower than the upper surface b of the drag washer 8 upon which the bobbin 6 rests, when mounted upon its spindle 4 while said projections 2 are sufficiently far from the .spindle as to be en tirely "clear of the base or flange of the bobbin 6, thus giving the bobbin 6 perfect freedom to rest upon the washers without being interfered with by said projections 2 The spaces'between the projections 2 are to afford access to the washers 3 in order that any accumulated fluffy or like matter may be readily removed by the attendant.

When using the washer holders 2 constructed as above described we arrange the lifter plate to be slidable lengthwise the machine while resting upon the upper ends of their lifter rods 7.

This is permitted by slots 5* being made in the lifter plate 5 (see 10) to span the upper ends of the lifter rods 7 while yet being supported by the flanges 7 on said rods.

When the dofiing has to commence, after the arresting of the machine and the adjusting of the lifter rail 5 and other parts as above described, the attendant will operate the handle to oscillate the shaft 41 so that by pinions 42 engaging racks 43 the step rail B carried by said racks, may be lowered in order to remove the foot-step bearings 44 clear of the lower ends of the spindles 4 in the usual manner.

After thus lowering the rail B we then lower the lifter rail 5 so that it and the drag washers 3 are clear of the lower ends of the spindles 4, the attendant then slides said lifter rail 5 longitudinally by the handle 5 in order to carry the washer holders 2 (along with the said lifter rail which is effected by a lateral. flange 2 taking into the openings in the lifter rail 5 as shown by Fig. 7 so that the vertical projections 2 on these holders 2 are brought beneath the flanges 6 (see Fig. 11) at the lower ends of the bob- I bins 6 by which means certain portions, of

said flanges will overhang said projections and thus afford spaces beneath said flanges for the insertion of the holding shoe 8 which may thus be brought into position to support said bobbin 6 upon its spindle 4 and permit the lifter plate 5 to be further lowered out of the way of the spindles 4 as is shown (see Fig. By this arrangement of the parts described bobbins 6 may on the removal of the shoes 8 be permitted to fall or descend from their respective spindles 4 on to the pegs 9 fixed upon a peg rail 10 arranged to receive them as is shown by Fig.3.

The moving forward of the spindles 4 from their operating positions shown by Fig. 2 to their advanced positions shown by Fig. 3 is effected by the supporting rail 11, which has the upper bearings 11 for the spindles 4 mounted upon it, being mounted to oscillate upon its bearings in well known manner; the said movement of the rail 11 being effected by the handle device 12 which the attendant actuates to move the well known toothed quadrants 13 and 14 arranged in connection with the rail 11.

After the parts have been adjusted as stated the attendant will then operate the handle 15 to bring the shoes or bobbin holders 8 from the position they occupy as shown by Fig. 3 into the rear position shown by Fig. 4 so that the bobbins 6 on the spindles 4 are permitted to fall or descend on to the pegs 9 as is before stated. hen the bobbins have thus descended on to the pegs 9 he then moves the spindles a short space forward by actuating the handle 12 after which the rail 10 upon which the pegs 9 are fixed is turned upon its bearings (upon which it is mounted to oscillate) from the position shown in Fig. 3 into the position shown by -Fig. 4 at which time a rod 20 will have moved by gravity along the curved slots 21 in the brackets 21 which is also fixed upon the rail 10, into the position shown by Fig. 4 and will have carried with it the threads or yarn 6 extending from the bobbins 6 so that any of such threads 6 which might have encircled the ends of the spindles 4 as they were being uncoiled from their bobbins 6 (somewhat as is shown by Fig.3) will by the descending movement of the rod 20 be carried beyond the ends of the spindle 4, thus leaving said thread free to be acted upon as is well known.

The attendant then operates the handle 12 so as to bring the spindles 4 into the position shown by Fig. 5 in which said spindles are in perfect alignment with pegs 16 upon which the empty bobbins 6 are situated. When the spindles 4 are thus in alignment with the pegs 16 the attendant then revolves the hand wheel 17 which (by well known gearing) raises the racks 18 so that a thread cutter 19 mounted at the upper ends of said racks 18 will come in contact with the lower ends of the bobbins 6 and raise said bobbins on to the spindles 4 on which the shoes or bobbin holders 8 will again be operated by the handle 15 to cause said holders to pass beneath the bases of the empty bobbins 16 and retain them on the spindles 4. After this adjustment of the empty bobbins the attendant will readjust the lifter rail 5 and then will further move back the spindles 4 and the bobbin holders 8 from the position shown in Fig; 3 tothe position shown in Fig. 6 this being effected by the usual and well known handle devices which are opera-ted in the manner hereinbefore explained.

On the parts being readjusted in the positions shown by Fig. 6 the attendant will then operate the handle 40 to readjust the rail B in its position'for its foot-step bearings to support the spindles 4. He will then operate the hand wheel 17 to raise the racks 18 in order to lift the thread cutter 19 into the po tion "shown by said Figmfiso that on the machine being started into motion the attendant may slide said thread cutter in known manner lengthwise the machine to sever the threads after same have been wound for the desired number 05E turns or coils around the bobbin 6, by the commence nient oi the spinning operations.

The form of foot-step bearing 44 which we employ'is produced by a body member having an inner member l-i? forced into a central opening made axially therein. The inner "member has its upper part of less diameter than the part below so that an inner annular space '20 is formed at this part to receive lubricant which will flow over the upper end to enter the cavity a" where the end of the spindle is supported and where it rotates. The'body'meniber is mounted in an opening made in the step rail B and is held against rotation by a screw 45, while by the nut 46 taking over the screwed part of the member 44E, this latter may be adjusted vertically to meet any :of the requirements of the spindle 4..
