FLIER SPINNING, TWISTING, AND SIMILAR MACHINE.

Application filed J'une- 6, 1914. Serialllo. 843,529.

To all whom it may concern:

Be it known that I, ROBERT HAMPE, manufacturer, citizen of the Duchy of Brunswick, residing at Helmstedt, Germany, have invented certain new and useful Improvements in Flier Spinning, Twisting, and Similar Machines, of which the following is a specification.

My invention relates to improvements in flier spinning, twisting and similar machines, and more particularly in machines in which the flier spindles are mounted in stationary bearings. In machines of this class the pegs, bells, or the like for the supply of empty bobbins and the for the reception of full bobbins from the flier spindles are disposed in two or more rows which are immovable relatively to each other and mounted on specialsupporting members, such for example as two parallel rails connecting the supporting members, and the said supports or rails have been so mounted as to be horizontally and vertically movable in such a way that the pegs or bells orthe like of the bobbins can be positioned coaxially of the spindles of the fliers. In order to vertically move the supporting member, which is necessary in order to remove the rails carrying the bobbins and the foot step bearings, comparatively much power is necessary, because the supporting member and the pegs, bells, or the like which are mounted thereon are comparatively heavy. Thereby the operation of the apparatus for exchanging the bobbins is made inconvenient.

The object of the improvements is to provide amachine of this class in which it is not necessary to shift the supporting members and the bobbin pegs or the bells provided in lieu thereof in vertical direction, for which purpose the rail which imparts vertical reciprocating movement to the bobbins during the spinning operation and in some cases also the rail carrying the foot step bearings of the flier spindles is mounted for vertical shifting movement on the supporting members or the guides thereof, while the supporting members are so mounted as to be incapable of vertical shifting movement and located so low, that the members such as pegs or bells which carry the bobbins can be brought in alinement with flier spindles simply by the horizontal displacement of the said supporting members. Thereby the construction and the operation Specification of Letters Patent.

egs or bells Patented Oct. 3, 1916.

of the mechanism for exchanging the bobbins are made more simple. Furthermore the improved mechanism is particularly suitable when reconstructing old spinning machines.

For the purpose of explaining the invention several examples embodying the same have been shown in the accompanying drawings, in which the same letters of reference have been used'in all the views to indicate corresponding parts.

In sa d drawingsFigure '1, is a front view of the flier spinning machine provided with my improved apparatus for exchanging the bobbins, Fig. 2, is a partial plan view of the machine shown in Fig. 1, Figs. 3 and 4, arefront views showing a modification of the machine with the parts in difl erent positions, and Fig. 5, is a view similar to that shown in Fig. l with some arts removed and showing a further modification.

frame of the machine consists of a plurality of uprightsl each carrying on a bracket 2 a horizontal guide rod 3 providing a support for a slide 4. The slides carry at their outer ends a rail or plate 7 to which two rows of bobbin pegs 8 and 9 are secured so as to be nonshiftable relatively to each other. By shifting the slides 4 on their rods 3 the pegs 8 and 9 can be set in alinement with the spindles of the fliers 18 for exchangingthe bobbins. As shown in the drawings the slides 4 are shifted by means of a shaft 14 mounted on the machine frame 1, and pro- In the example shown in Figs. 1 and 2 the vided with gear wheels 13 one for each of x the slides 4. Each of the gear wheels is in mesh with rack teeth 4 provided on the cooperating slide. The shaft 14 is adapted to be rotated by suitable means such as a hand crank.

To the slides 4 vertical sleeves 5 are secured which provide guides for rack bars 6 formed with rack teeth. On the upper end of the said rack bars 6 a lifter rail 30 is wheels 12 are keyed with the rack bars 6. As is shown in Fig. 2 the foot step rail 34 is provided with open portions 31 which permit the passage of the. pillars 1 therethrough when shifting the slides 1 to the right inFig. 1. Similar open portions are provided in the lifter rail 30.

On the pillars 1 slides 25 are mounted which are adapted to be shifted in vertical direction by means of

gearings

16 and 28, the said slide carrying a shaft 27. To the said shaft arms 29 are secured which are provided for holding the full bobbins and lifting the empty ones. The slide 25 is formed in such a way, that the arms 29 do not extend into the paths of the fliers 18. Therefore it is not necessary to readjust the fliers 18 prior to dotting the bobbins. By means of the vertically movable lifter rail 30 the full bobbins are smoothly lowered, so that the threads 55 can be wound only on the lowermost part of the flier spindles.

The lifter rail 30 which continuously lifts and lowers the bobbins while the machine is in operation and which is located above the foot step rail 31, is provided with engaging devices 31 one for each of the spindles 18. lVhen the rail 30 is moving downward and on to the foot step rail 31 the said engaging devices move upward relatively to the rail 30 and thereby raise the bobbins 4.7 from the drag washers 32 of'the rail 30 to such an extent, that the arms 29 can easily engage below the flanges 117' of the bobbins. Therefore all that is necessary in my improved machine for dofling is to shift the foot step rail31 together with the lifter rail 30 which has before been lowered on the same, and to horizontally shift the slides -1 with the said rails.

lVhere the spindles are freely suspended and are not provided with foot step bearings, the foot step rail 31 can be rigidly secured to the sleeves 5. In this case the. only object of the rail 31 is to lift the engaging devices 31 mounted on the lifter rail, so that the flanges of the bobbins are disengaged, the sockets 31 striking on the foot step rail 31 and moving upward beyond the lifter rail 30 when the latter is moved downward. In this operation they lift the lower bobbin flanges 17 from the drag washers 32 of ,the rail 30, so that the arms 29 can easily engage below the flanges 17.

In the example shown in Figs. 1 and 2 the bearings -18 of the fliers 18 are suspended from the overhead rail 50 of the machine by means of balls or rollers 49 which are lo cated diametrically opposite each other at opposite sides of the bearings 18, the latter being provided with two notches which are open downward and the overhead rail 50 being provided with corresponding notches which are open at their top sides. By reason of this suspension of the fliers 18 the latter vas the

rails

30 or 31 moving upward, the

spindles can yield a little so that injury of the parts is avoided. As is shown in. Fig. 1 the driving belts 51 for the fliers 18 pass through openings 50 of the overhead rail 50. Thereby the driving belts 51 are protectcd against the dust, hairs and the like which fall from the feeding mechanism Besides the construction of the spinning machine is thereby made more simple.

For severing the thread when dotting and after an empty bobbin 17 has been placed 011 one of the fliers 18 and the latter has performed a'few revolutions for the purpose of attaching the end of the thread to the empty bobbin, severing mechanism of known construction may be provided. In the example shown in the drawings the said severing mechanism consists of a pair of

cutter blades

38 and 38 adapted to be shifted toward and away from each other by the hand of the operator after .the cutting mechanism has been raised to such an extent, that the threads 55 which are passed from the empty bobbins placed on the fliers 18 to the full bobbins on the pegs 9 extend between the cutting edges of the

cutter blades

38 and 38.

In Figs. 3 and -l I have shown mechanism for providing an accurate guide for the foot step rail 31 in Figs. 1 and 2. As shown the foot step rail 31 is normally held in operative position by means of springs 40 the power of which is such that they just overcome the weight of the rail 31 and yield when the lifter rail 30 is lowered on the rail 34, as is shown in Fig. 1. To the supporting members or bridges l or the rail 7 carried thereby brackets 35 are secured on which shafts 39 are mounted for vertical reciprocating movement. On the said shafts the springs -10 are coiled which engage. below collars 11 and press the shafts39 and the foot step rail upward to such an extent that the spindles 18 engage in the proper way in the foot step bearings 42.

For severing the threads when dofling a severing mechanism 38", 38 may be provided.

Instead of the bridges 4 shown in Figs.

1 and 2 which are movable in horizontaldirection carrying members maybe provided which have rocking supports on a stationary horizontal shaft, and which provide supports for the foot step rail 34. This construction is shown in Fig. 5. Each of the carrying members is in the form of a 1101- rails 30' and 34' which are adapted to be raised and lowered by means of racks 6 the rails 30 can pass into the hollow of the ring. In this position the part of the ring which carries the pegs 8 and. 9 moves beyond and 34 when the ring 56 is being turned. In the example shown in the figure the ring is adapted to be turned by means of a gear wheel 13 engaging in rack teeth 56 provided on the ring 56, the gear wheel 13 being adapted to be turned by means of aremovable crank 57 or the like. Common driving means may be pro vided for all the rings 56,.in which case all the gear wheels 13 are. secured to a common shaft 1 1.

Any known or preferred means may be provided for supporting the ring 56. i To show what may be done the ring 56 is rotata-bly mounted on a core 58 which is rigidly secured to the frame 1' of the machine and is provided with an open portion 58' for the reception of the rails 30' and 34.

The operation of the dofiing mechanism is the same as in ordinary machines, so that a detailed description is not necessary. For removing the full bobbins 47 from the pegs 9' after severing the threads 55 a carriage 59 may be provided which is supported with its wheels 60 on longitudinal rails 61 provided alongside the machine. When the said carriage is moved by the operator along the machine the full bobbins are collected from the pegs 9 by means of a stripping member 62 or the like.

The position which the parts assume during the spinning operation is represented in Fig. During the spinning operation the spool rail 30 rises and depresses alternately by means ofthe gear wheel 12 and rack 6 shown in Fig. 1, the wheel 12 being turned alternately by the weighted rope 45 engaging the pulley 10 mounted on the shaft 11 and by the cam 43 through the actuation of the lever 41 carrying a roller engaging said latter cam. If full spools are to be replaced by empty ones, the parts of the fliers 18 are first disposed in alinement, see Fig. l. The spool rail 30 is then lowered until it comes in contact with the bearing rail 34:, this operation being effected by the lowering movement of the weighted rope 45 engaging the pulley 10. Then the spool rail 30 descends it carries the foot bearing rail 34 downwardly therewith for a short distance against the tension of spring *0, as shown by Fig. 4, and thereupon the hook 29, Fig.

hook being swung around the shaft 27, and

after this latter engagement of the hook with the spool has ensued the said hook and spool are slightly lifted by means of gear 28 and rack 16. The carriage at is now moved to the right by the operatlon of the pinion 14 and rack 4, the movement of the said carriage being to such an extent as to place the spool pin 9 under the spindle 18. The hook 29 is released from the spool and the latter falls and is caught on the pin 9. The carriage 1 immediately following the latter operation is displaced slightly to the left or until the pin 8 carrying the empty spool is moved under the spindle 18. The hook 29 is then caused to engage under the upper flange of the empty spool 47, as shown by Fig. 1, and the said empty spool is moved upwardly until it is pushed upon the spindle 18. The carriage 4c is next shifted to a greater distancev to the left or into the position shown by Fig. 1 and the spool rail 30 is again raised whereby the foot bearing The thread is first wound to some extentv upon the empty spool and is then cut off in a Well known manner.
