CIRCULAR CoMBfNe MACHINE.

SPECIFICATION forming part of Letters Patent No. 357,171. dated February 8. 1887.

I Application tied May 18,1886. serial matassa. (No model.)

143,807, and November 13, 1884, Serial No.

147,824, respectively, the present improvements having for their object to provide an improved jaw for holding the sliver and giving to it the necessary tension immediately i' v before it is delivered to the combs, an improved means of feeding the required length of sliver at each revolution of the feed-drum, and an improved means of regulating the relative speeds of the circular combs and the feed-drum to prevent the oblique dragging of the sliver.

^ In carrying out my invention the balls of sliver are supported in arms and upon rollers mounted in the arms atthe top part of the machine. Each sliver passes down behind circular guide-rails which `surround the feeddrum, and from thence through a hole in the top of thetens'ionj aw. The sliver thcn passes under a brass rail and then under the jaw, where it is nipped between the under 'surface of the jaw and the upper surface of a bearer,

, to which the jaw is jointed. The sliver fmmediately after passing between. the jaw and the bearer is delivered to the' combs in a perfeetlylat fan-shaped fringe. The bearer which carries the tension-jaw is jointed to a iiangeA connectedto a boss which drives the feed-drum,

and the bearer is caused to rise at the required,

part of its revolution by means of a bridge or inclined bar or bars xed at a suitable angle,

and over which bar or bars the bearers travel' in their revolution. As the bearers pass up the incline the sliver is pulled down from the creel by means of the curved feed-bar, which v holds down the end of the sliver as the tenseparator.

to the dabbing-brush, at which point the larger and smaller circular combs are almost in contact. At this point the bearers upon which the jaws are mounted drop off the end of the bridge or curved bar, which here terminates, and as the end of the sliver is held between the jaw and the bearer this latter, in dropping, pulls down a portion of sliver fromf the creels and thereby assists in feeding the required length of sliver.

In order to prevent the sliver from dragging or being pulled back obliquely between the feed-drum and thecombs, the gearing beneath the combing-table which drives the circular combs and the feed-drums is so speeded that the combs are driven rather faster than the feed apparatus, whereby the tendency to drag thesliver is compensated for and the sliver is delivered to the combs in true radial lines. The dabbing-brush is driven in the ordinary way.

In order to enable my invention to be fully understood, I will proceed to describe the same by reference to the accompanying drawings, in Which- Figure 1 represents a sectional elevation of a combing-machine constructed according to my invention. Fig. 2 represents a plan of the same with the feed-drum removed. Fig. 2* represents a side elevation of the star-wheel Fig. 3 represents. a perspective view, enlarged`Z of one of the tension-jaws and bearers. Fig. 4 is a front view of one of the tension-jaws. Fig. 5 is aplan of the combingtable, showing the bridge or curved barsupon which the bearers travel during partof their revolution, and Which may be adj usted to give the bearers the required rise or elevation, and also showing the toothed rim and its driving-pinion. Fig. 5* represents a detail view of thebridge or curved lbar and its means of adjustment, and Fig. 6 represents a plan of the gearing beneath the combing-table, which is driven by the main driving-shaft and actuates the two circular combs and the feed-drum.

Similar letters `refer to similar parts in all the figures.

The larger and smaller circular combs, A and B, respectively, are caused torev olve upon steam-Chests O and D. VThe large comb, A, is driven by means of a rack of internal teeth, E,

.into which is geared a pinion, 1, actuated by the gearing A2 beneath the combingtable, and the smaller or internal circular comb is driven by means of a rack of external teeth, F,which are also driven from said gearing A beneath the table.

The broad lower flange, J, of the drum G is mounted upon a rim, K, having a toothed internal periphery, L, and revolving upon the circle M. Upon the bearers N are jointed the tension-jaws l?, and these bearers are hinged to the top fiange, H, of the drum G, and are carried round with the drum as it rotates. A projection at the bottom of thc bearer N rests upon the circle O, upon which it travels dur ing part of its revolution. rI'he lower part of said bearer during the remainder of each revelution o f the drum rests or travels upon the bridge or curved bar Q, which is, by means of set-screws 2, adj usted and fixed at the required angle to cause the bearers N to rise to the necessary height, so that a sufficient quantity of the sliver R may be pulled through the opening between the j aws l) and the bearers N, at which opening the sliver is nipped by the weight of the jaw l?.

The sliver B passes down behind the guide S, which is fixed to the periphery of the feed.- drum U, secured to the shaft W, which feeddrum is driven by means of an arm, 3, attached to said shaft, and an upright s1'iindle,V,workin g in a hole, 4, in said arm,which spindle is fixed to the flange H. The sliver then passes through the opening in the arched top of the jaw l", and under a circular rail, T,which rail is supported by uprights and brackets to the flange J. After passing under the rail T the sliver is drawn under the outer weighted end of the j aw P, from whence it passes direct to the combs. This rail Tis for thepurpose ofgiving the sliver the proper tension before it reaches the combs, and also for holding said sliver off from the weighted cnd of the jaw and from the combs, to prevent said sliver from either slacking or being drawn back, and thereby preventing an irregular feed.

During the revolution of the feed-drum the ends of the fringe of sliver projecting from the nip of the jaws P are caught under the curved feed-bar X, Fig. l, and as the bearers are at that time traveling up the incline ofthe bridge Q a certain :regulated portion of the sliver is pulled from under the jaw l), the weight of which jaw gives the required tension to the sliver. The fringe thus pulled out is lifted out of the inner comb by means of pointed knives in the ordinary manner, then passes over the dead-plate Y to the dabbing-brush Z, where the fibers are dabbed into the teeth of both circular combs,which come together at a point beneath the dabbing-brush. After the bearers N and the tension-jaws P have passed the dabbing-brush Z the sliver then contained in the combs is separated between the combs by means of a star-wheel, 5, Figs. 2 and 2*, and at this point the bearers drop off the end of the bridge or curved bar Q, and thereby pull down a regulated length of sliver R from the balls at the top of the feed-drum.

The two circular combs A and B are driven from the gearing AZ, and the drum U of the feed apparatus is driven from the gearing G.

The two circular combs Aand B are driven at the same surfacespeedthat is, so that they will both complete one revolution at the same moment. The speed at which the combs A and B are revolved is a little faster than the speed at which the drum U of the feed apparatus and the bearers with their tensionzjaws are caused to revolve. the combs over that of the bearers and jaws prevents the fringe of sliver from dragging or being held back obliquely after the sliver has been plowed out of the comb and when it lies loosely upon the dead-plate Y. rlhe greater speed of the combs over that of the feed-drum will overcome this tendency of the sliver to drag, and thus cause the same to be delivered tothe combs in true radial lines.

The circular combsA and B receive motion from the vertical shaft C, which passes through the table D of the machine and drives the combs by means of gearing F', mounted upon the upper side of the table. The bearers N, carrying the tension-jaws P, with the feeddrinn and its fianges H and J, are driven by a pinion, E2, fixed upon the upper end of the shaft E', which pinion gears into the internal teeth, L.

The gearing AZ, which drives the two circular` combs A and B andthe feed-drum G, is actuated by a vertical shaft, B2, which is driven by means of the bevel-wheels B from the main shaft A.

The dabbing-brush Z is fixed to the upright shaft G', which works in brass bushes fixed to the upright frame H. The upright shaft G is given a reciprocating motion by means of the pulley C2, spindle L, eccentric K, and eccentric-rod Z3, one end of which is fitted to the cc'- ccntric and the other end is jointed to a stud fixed upon the shaft G.

rlhe grooved wheel C2 on the eccentric-spindle L is driven by means of a cord, D2, from the grooved wheel M,fixed upon the main shaft A. The fast and loose pulleys upon the main shaft are represented at N and O,rcspectively, in Fig. G.

Having now particularly described and ascertained the nature of thcsaid invention and Vin what manner the same is to be performed,

I declare that what I claim is- 1 1. The combination, with the bearers N, of the tensionjaws P, hinged to said bearers and formed with open tops, substantially as shown and described.

2. The combination, with the bearers N, of the tension-jaws P, hinged to said bearers and formed with open tops, and the tensiou-rail-T, substantially as shown and described.

4. The oornbinatiomwith two circular combs and means for driving the same at the same surface-speed, of a'feeddrum, bearers, and

X, substantially as and for the purposes set forth.

.6. In combination, the tension-jaws P, bearers N, bar or bars Q, means for vertically adj usting the same, feed-bar X, two circular combs, one within the other, means for driving the same, the feed apparatus, and means for driving the same at a speed somewhat slowerl than that of the combs, substantially as set forth.

7. In combination with the jaw P, bearer N, means for imparting vertical movement to said jaw and bearer, the inner and outer combs, A and B, and the tension-rail T, all substantially as shown, and for the purposes described.
