DRAWING-FRAME FOR TEXTILE FIBERS.
SPECIFICATION formingpart of Letters Patent No. 755,347, dated lslarcll 22, 1904.
' Application filed February 26, 1902. Serial No. 95,769, (No model.)
To all whom it may concern.-
Be it known that I, ALFRED BIETENHOLZ, a
residing at 'Li'issum-Blumenthal, in the Prussian Province of Hanover, Empire of Germany, have invented certain new and useful Improvements in Drawing-Frames for Textile Fibers,'of which the following is a specification-.
My invention relates to improvements in drawing-frames for textile fibers of that kind in which a porcupine-roller is arranged between the feed-rollers and the drawing-rollers and beneath the sliver. Such drawing-frames,
however, present two great defects:-'First,-
the sliver does notpass in a straight line or plane from the feed-rollers to the drawingrollers, but is bent over apart of the circumference of the porcupine-roller, so that the sliver, by reason ofits tension, becomes compressed on the roots of the needles; second, the sliver so compressed cannot again leave the needles of the porcupine-roller without its fibers being strained-beyond their limit of elasticity or in case of wool losing their desirable curl. I
My invention relates to improvements for remedying. these-defects, so that the sliver passes in a straight line or plane from the feed-rollers to the drawing-rollers while being stretched and remaining loose without its fibers being unduly strained or in case of wool losing their curl.
The objects'of my improvement are, first, to provide also above the sliver a pgmirin eroller of comparatively small dia neter and having as many needles as possiblefsecond,
.to provide either a smooth guiding-roller or an additional porcupine-roller beneath the sliver, the one or two lower porcupine-rollers being smaller in diameter than the upper porcupine-roller and having as many needles as possible, and, third, to so arrange the porcupine-rollers and the smooth roller that, if employed. the sliver passes in a straight line or plane from the feed-rollers to the drawingrollers, it being in all cases optional to employ either a single pair of feed-rollers or two consecutive pairs of feed-rollers, according to 5 the kind of textile fibers to be drawn.
In the accompanying drawings, Figure 1 stretching part of a drawing-frame provided with two porcupine-rollers only.
1 The drawing-frame shown at Fig. 1 has two consecutive pairs of feed-rollers a b and 0d,
two lower porcupine-rollers e and 9, one up- ,per porcupine-roller f, and a pair' of draw- Inorder to give a better ideaof the drawing-frame, the diameters of ing-rollers 7; and 7;.
the several rollers may be taken, for example, as follows: lower-front roller a, (which is positively .driven,) fifty, millimeters; upper feed-roller 6, (taken along by friction only.) eighty millimeters; lower rear feed-roller 0,
'(positively driven,) twenty-five millimeters;
upper rear feed-roller d, forty millimeters;
the two lower porcupine-rollers e and g, (positively driven,) forty-eight millimeters; upper porcupine-roller f, (positively driven) seventy-two millimeters; lower drawing-roller h, (positively driven,) twenty-eight millimeters over all, and upper drawing-roller, forty-four millimeters outside. As will be seen from these dimensions, the upper porcupine-roller f -is comparatively small in diameter, while the two lower porcupine-rollers e and g are considerably smaller in diameter than the upper one f. All the three porcupine-rollers have as many comparatively short needles as possible. For example, the upper roller has on its periphery thirty-four needles and the lower roller 6 has twenty-four, and the lower roller g thirtyfive needles on the circumference. The drawing-rollers h and c' are assumed to be fluted longitudinally, and an endless band is, of leather or the like, is passed between them, which is maintained in its stretched condition by a guideroller above the roller 2' or below the lower roller h in case the band passes from below over the roller h downward. The drawing-rollers it i and the feed-rollers a b and c d are pressed on each other in any well-known manner by springs or by weights acting upon levers. The needles ofthe three porcupine-rollers intersect the sliver Z only so much that the sliver Z is held on the teeth intermediate of the points and the roots, so that it can pass freely from the same in the regular feed of the machine. Moreover, the needles of all the porcupinerollers are set so narrowly that they will divide the several textile fibers and facilitate the drawing operation of the drawing-rollers It i, so that the fibers are also placed parallel to each other. Then the drawing-rollers 7i i can draw the sliverl with perfect safety, while the sliver remains loose and by reason of its tension passes in a straight line or plane from the feed-rollers 0 (Z to the drawing-rollers it The sliver enters and leaves the three porcupine-rollers easily, and its fibers retain their fulll elasticity and in case of wool also their cur Of course it is quite immaterial whether the drawing-rollers 7L 1; be fluted, as shown, or smooth, and constructed in any known manner, the essential point being that the necessary friction between them is produced for insuring the drawing operation.
For shorter fibers preferably only one lower porcupine-roller g, as shown in Fig. 3, is employed, so as to reduce the distance between the feed-rollers m a and the drawing-rollers h i. The lower porcupine-roller 0 (shown in Fig. 1) is omitted and replaced by a smooth guiding-roller 0 for supporting the sliver Z. This guiding-roller 0 is located immediately behind the pair of feed-rollers m n; otherwise the arrangement is the same as in Figs. 1 and 2, and the corresponding parts are indicated by the same letters, only that the index has been added.
Having thusdescribed my invention, I claim as new and desire to secure by Letters Patent 1. In a drawing-frame for textile fibers, the
combination with a set of feed-rollers and a set of drawing-rollers, for feeding and drawing the sliver, of 'two lower porcupine-rollers beneath the sliver and between the lower of said feed-rollers and the lower of said drawing-rollers, and an upper porcupine-roller above the sliver intermediately between said two lower porcupine-rollers, said three porcupine-rollers being small in diameter and having as many needles as possible and arranged for intersecting the sliver, and all of said rollers being so arranged that the sliver passes in a straight line or plane from the feed-rollers to the drawing-rollers, substantially as set forth.
2. In a drawing-frame for textile fibers, the
combination with a set of feed-rollers and a set of drawing-rollers, for feeding and drawing the sliver, of a lower porcupine-roller beneath the sliver and between the lower of said feed and drawing rollers, and an upper porcupine-roller above the sliver acting in conjunction with the lower porcupine-roller, said porcupine-rollers being small in diameter .and having as many needles as possible and arranged for intersecting the sliver, and all of said rollers being so arranged that the sliver passes in a straight line or plane from the feedrollers to the drawing-rollers, substantially as set forth.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
ALFRED BIETENHOLZ.
