METHOD OF PREPARING WOOL FOR SPINNING.

SQECTFECATION forming part of Letters Patent; No. 357,486, dated February 8, 1887.

Application filed January 30, 1886. Serial No. 190,367. (No specimens.) Patented in France December 8, 1884, No. 163,461; in

Bc'gium November 30, 1885. No. 70,800, and in England June 18, 1886, No.1,584.

T aZZ whom, it may concern.-

Be it known that I, PETER Lnnwrc KLEIN, of Dusseldorf, in the Kingdom of Prussia and ,Empire of Germany, have invented a new and ation-called the preparation-is that of thinning out and parallelizing this sliver and preparing it for the spinning-machine by forming it into roving yarn, which is then passed onto the third operation of spinning on the spinning-machine.

My invention relates to the second operation, called the preparation, being thetreat ment of the combed wool coming from the combing-machine until it is formed into roving yarn ready for the spinning-machine; and it consists in substituting carding-engines for a certain number of the drawing-frames now used in this operation of preparation,whereby not onlya great saving in the machinery necessary for this operation is effected, but also its cost materially reduced.

As 110w practiced, the operation of preparation is as follows: The combed wool coming from the combing-machine is passed through a number of drawingframes varying from seven to thirteen, according to the material used, the two last of these frames being called the finisher and the fine finisher, respectively The combed wool coming from the combing-machine is passed through agilibox and formed .into slivers, which are then passed to the first drawing-frame, on which three or four slivers are united and thinned out into a single one. Of these latter, three or four are again united on the second drawing-frame and thinned out into a single one, and in this way the single slivers coming from each drawing-frame areunited by fours, threes,

and gradually by twos, and thinned out on the next following one, until they reach the fin isher and fine finisher, on both of which only two slivers are united and drawn out into one, the fine finisher delivering the roving yarn ready for the spinning-machine. The entire operation is a very tedious and expensive one, each frame having to be attended by at least one person, and it requires considerable time to pass a given quantity of material through all of these frames.

By my improved method the operation "of preparation is greatly simplified, the time required for the same greatly reduced--to about one-half-and its expense lessened in about the sameproportion.

For all the drawing-frames mentioned above as being now used-with the exception of the finisher and fine finisher, which I retain--I sub stitute two carding-engines, the first of which I call the preparing-card, while I term the second the thinning-card, \Vhile, in the method as now used, the material coming from the combing-machine has to be formed into a sliver by the latter or by a gill-box, in order to be passed through the drawing-frames, I bring the combed wool either in shape of loose flakes or of slivers or pieces of slivers onto 1 which is wound upon bobbins and then passed to the finisher, is exactly equal to that which in the old method passed through the entire train of gill-boxes and drawing-frames previous to reaching the finisher.

In the old method the bobbins prepared on one gill-box or drawing-frame have to be ar- 9 ranged on the next frame, and the latter stopped meanwhile, as also when one bobbin, having run off, has to be replaced by a fresh one, which causes a great loss of time. In my improved method any given quantity of combed Iuu wool can be run through the two cards which I employ, in a continuous operation, delivering the bobbins to the finisher in about onehalf the time required therefor in the old method, while also only one hand is required for attending the two carding-engines, thereby saving greatly in actual wages.

There is no novelty in the construction of either the preparing or the thinning card,both being carding-engines of well-known construction 5 butnever heretofore have carding-engines been employed in the preparation of combed wool for use in fine spinning, whereby roving yarn for the spinning-frame is produced from d combed wool coming from the combing-machine. I do not therefore claim any novelty in the construction of the cardingeugines which I employ in the operation of preparation; but neither do I confine myself to the number of them, as I may, according to the material, find one oi'them sufficient for my purpose; or I may employ more than two, a saving of time and actual expense resulting in any case; but

What I claim as new, and desire to secure by Letters Patent, 1's

1. The improved method, substantially as herein described, for the preparation of wool, which'consists in carding and combing it, again subjecting the wool thus carded and combed to the action of a carding-engine, and then drawing it, as and for the purpose set forth.

2. The method, substantially as herein described, for the preparation of wool, which consists in first carding it, then combing it, then again subjecting it to the action of carding-engines, and then subjecting it to the action of the finishing and fine-finishing drawiug'fraines, as set forth.
