DRAWING-MOTION OF COTTON-COMBING MACHINES.

SPECIFICATION forming part of Letters Patent NO. 730,711, dated June 9, 1903.

Application filed February 1, 1902. Serial No. 92,136. (No model.)

To (all whom it may concern:

Be it known that I, JAMES SLATER, foreman carder, a subjectof the King of Great Britain, residing at Oxford'Mills, Ashton-under-Lyne, in the county of 'Lancaster, England, have invented new and useful Improvements in the Drawing-Motion of Ootton-Oombing Machines, of which the following is a specification.

This invention relates to an improvement applicable to the drawing-motion at the delivery end of cotton-combing machines; and

the objects of the said inventionare to diminish the draft and at the same time toincrease considerably the productive capacity ton-combin g machine to illustrate in what-relation to the carding-rolls the drawing-rolls are placed.

A cotton-combing machine usually consists of a series of from six to ten heads AQB, and O, which are arranged along the side of a polished iron plate, along which the slivers proceed in parallel lines in the direction of the arrows, Fig. 5, toward the drawing-rollers at the delivery end of the combing-machines. Hitherto the drawing-rollers a. have been made in one continuous length, whereby the whole number of slivers would pass through them into a single trumpet c,then through the calendering or delivery rollers 19 into a single cant'. e., tenv slivers into one can. According to my invention I divide the drawing-rollers a into two sectionsand pass only, say, four or (see Fig. 5,) and each section of four or five ends passes through a separate trumpet c and then through the calendering or delivery rollers 12, each four or five ends into a separate can.

According to the old method the speed at which the combing-machines could be worked and the slivers drawn and delivered into the coiling-cans was limited by the maximum speed at which the coilers could be worked;

otherwise the draft was too great and the centrifugal force developed interfered with the coiling action.

I have discovered that by dividing the delivery into two sections and passing each section into a separate can running at the ordinary speed the speed of the combing-machines could be very considerably increased and the draft diminished,"thus almost doubling. the output without deteriorating the quality of the product, or instead of using one drawbox with the rollers divided into two sections, as illustrated, I may employ two draw-boxes with ordinary rollers,' each provided with a separate coiler, one placed at the delivery end of the combing-machine and the other at .or-near the center of the machine, and al- JAMES SLATER.
