Thisinvention relates to textile machinery and more especially to the drawing frames forming part of spinnin and other textile machines.
It is more especially concerned with the type of drawing frame carrying pivot-less drawing rollers and with an iihprclvementof the weighting device for the top rollers of the drawing set.
Drawing frames are known, in which the weighting of the top rollers is effected by means of a spring acting on a pluralityof top rollers, the weighting action of the spring being transmitted ontothe individual rollers by means of asaddle. Combinations of this kind have been used in drawing frames provided with pivots for the top rollers and also for pivotless rollers, but they involve the drawback that whenever the drawing set is being adjusted, the ratio of mutual weighting of the individual rollers undergoes a change which has an unfavorable influence on the spinning operation. Therefore,- as a rule, a second saddlemust be resorted to, if adjustment within wide limits is required.
In the drawing frames according tothe pres: ent invention each top roller of the drawing set has its own weighting spring which is so arranged that the degree of loading exerted by it on its roller does not undergo a change when the drawing set is adjusted. Obviously this enables a distribution of the load over the individualrollers to be dispensed with. a
The arrangement according to this inventionbeoomes particularly simple if the holders of the individual pivotless top rollers are resiliently yielding members. In this case the associated; yielding holders of a drawing set can be guidedand supported in a rail; preferably of U section, extendin above the top rollers in parallel to the drawing set their weighting effectonthe individual rollers always remaining the same reardle'ss of the adjustment ofthe set. I
This arrangement is further im-prdved by fixing onthe rail together with the yielding top roller holder also a holder for the clearer roller insuch a manner that this latter holder can be shifted together with the yielding top roller holder. In this combination the clearer roller always automatically assumes the correct position relative to the top roller, I prefer to so fashion the holder for the clearer roller that it embraces the channel-shaped rail, guiding the loading spring at its bottom part and keeping it under prelim-- inary tension when the drawingframe is relieved of ,th W1- The guide rail for the resilient top roller holders is preferably supported at its upper end for rocking motion relative to the holder bar and its front end is positivelyconnected with thereversing rail. Since in this case the reversing rail is relied upon to support part of the top roller weight, I prefer reinforcing it and bolting it to the roller stand. H
Owing to this arrangement of the weighting device any detached hooks or combed slivers can be dispensed with altogether and the calendar rollers, on which laps might form, can be mounted in place and removed without requiring the load on-the drawing frame to be relieved. The member connecting the reversing" rail with the channel rail will secure this latter against; any sidew'is'e displacement whereby an accurate parallel guiding of the top' and bottom. rollers is obtained. 7
In the drawings afiixed to this specification and forming part thereof an embodiment of this invention is illustrated diagrammatically byway of example.
In the drawings 0 Y Fig. 1 is a diagram showing; artly in vertical section, adrawing frame according to this invention, the parts being in operating position.
Fig. 2 is a similar view of the frame, however, with the top rollers in raised position.-
Fig. 3' is a' partial plan view, drawn to a smaller scale, and,
Figs. 4 t'o 6 are sectional detail views. A
Referring to the drawings and first to Figs. 1-3, I is the U-shaped guide rail or channel and 2, 3 and" 4' are the resilient holders, guided in this ch'annel, of the tap mu'eis 5,5 and 1, respectively, their top end's' being fixedto the rails by means of screw bolts 8, 9 and It, respectively, which also connect to the rail the holders II, I 2 and [3 for the clearer rollers (Fig. 4). Near the free ends of the resilient holders 2;. 3 and l are fixed yqy means or'rivets gripping springs (4-, 1's
an I6, respectively; oif s"imilar me'ans for suppgiifting'the top rollers 5, 6 and 1 ina resilient or yielding manner. The rail- I is supported by its top end for rocking movement on the holder bar l1. N ear' its free endit can be positively conheated by of the hOok shaped members I Q and 2ll- (Figs. '2 and 5 Al with the-reversing rail [8 to the roller stands. I u
Fig.3 shows a longitudinal slot- 24 formed in the niddle web of the rail I which serves for adjusting the set-a graduation 25 (Fig. 3) being provided near this slot. u
Fig-.- @A shows on alarger scale the middle top roller 6 with-its resilient holder ii andthe gripping spring l5. The screw bolt 9 fixesthe holder 3 together with the holder I2 of the clearer roller 2| to the rail I, the holder I2 keeping the holder 3 under preliminary tension. This figure also shows that the clearer roller 2| is always maintained in the same position relative to the top roller 6 it is associated with. r
Fig. 4B shows the clearer ro1ler holder I2 a embracing the rail I and guiding the resilient holder 3 at its free end.
Figs. 5A and 5B illustrate the connection between the reversing rail I8 and the channel rail I, a member I9 embracing the reversing rail and being formed as a hook at its top end. This hook-shaped portion is formed with an open notch 30 in which rests the channel rail I. On the rail I there is mounted for rocking movement at 3| another hook-shaped part 20 which together with the part I9 enables a readily disengageable connection to be established between the top roller holder I on the one hand and the reversing rail I8 and the roller stand I8 on the other hand. If this connection is so organized, for instance by means of a spring (not shown) acting on the part 20, as to be established automatically as soon as the members I9 and 20 contact each other, all that is needed for weighting the drawing frame is to move the rail I downwardly until the hook 20 has gripped the hook I9. In order to disengage again the parts, a slight pressure exerted on the top end 32 of the double armed lever 20 and on the bottom of rail I will be sufiicient to release the latter.
Fig. 6 illustrates the way in which two ends of the reversing rail I8 are connected to the roller stand 23 by means of screw bolts 22.
I wish it to be understood that I do not desire to be limited to the details shown and described for obvious modifications will occur to a person skilled in the art.
