I IMPROVEMENT IN DEVICES FOR DIVIDING FLEECE FROM A CARD INTO SLIVERS.

Specification forming part of Letters Patent No. 15 [,678, dated June 9, 1874: application filed March 18, 1874.

To all whom it may concern:

Be it known that I, EMILE BEDE, of the firm of Bede and Company, of Verviers, in the Kingdom of Belgium, engineers, have invented certain improvements in apparatus for dividing cardings of wool or other fiber into strips or slivers, and rubbing them into rovings, of which the following is a specification This invention consists in the improved apparatus hereinafter described, and illustrated in the accompanying drawings, for dividing the sheet of wool or other fiber, as it leaves the carding or condensing engine, into a series of strips or slivers, and rubbing the same into rovings.

Figure 1 represents, in longitudinal section, part of a carding-engine, with apparatus applied thereto, constructed and arranged according to my invention. Fig. 2 is a sectional view (drawn to a larger scale) of my improved dividing and rubbing apparatus detached,

' showing a modification of the rubbing apparatus represented in Fig. 1. Fig. 3 is part of a front elevation of Fig. 2. Figs. 4, 5, 6, 7, 8,

t), and 10 are sectional views, illustrating modifications of the arrangement shown in Figs. 1,

2, and 3, as hereinafter described.

Similar letters of reference are used to indicate like or equivalent parts where they occur in Figs; 1, 2, 3, 6, 7, S, 9, and 10. The letters of reference are omitted on Figs. 4 and 5, in order not to crowd the said figures, as they will be readily understood without such indications.

P, Fig. 1, represents the doffer of a cardingengine, and p is the doffer-comb, for stripping the sheet'or web of wool or other fiber n from the dofi'er. r is a small revolving roller, which keeps the said sheet or web of fiber in a suitable state of tension. F F, Figs. 1 and 2, are a pair of endless leather aprons or bands, mounted on and traveling around revolving rollers in the directions indicated by the arrows. In front of the endless apron F is a horizontal cross -bar, V, and in front of the endless apron F is another horizontal cross-bar, V, the ends of the said cross-bars V V being attached to the frame of the machine, so that, if required, the said bars mav be set farther apart, one from the other. T is a double cross bar, situated behind the traveling aprons F F, and at each end affixed to the frame of the machine, or to brackets or supports carrying the rollers of the endless aprons F F. d d are strips or blades of steel for dividing or separating the sheet or web of fiber into slivers. The said steel strips (1 d are fixed, alternately, to the upper and to the lower cross bars V V, and from thence pass between the endless aprons F F, and, by their other ends, are fixed, respectively, to the lower and upper edges of the double bar T, behind the said endless aprons, the ends of the strips d being affixed to the bar V, and to the lower part of the bar T, and the strips (1 being affixed by one end to the bar V, and by the other end to the upper part of the double bar T.

The arrangement and mode of connecting the ends of the steel strips 01 01, respectively, to the bars V V and to the double bar T will be readily understood by reference to Fig. 2, and the way in which the said steel strips or blades are made to cross each other is clearly exhibited in Fig. 3.

R B, Fig. 1, are endless rubbing aprons or bands, mounted, each, upon two rollers, which receive rotatory motion, andalso reciprocat ing motion, in the direction of their axes, in the usual manner. The said endless aprons RR work in connection with the endless aprons F F, respectively, as shown in Fig. 1 5 or, instead of the endless rubbing-aprons R R hereinbefore described, and illustrated in Fig. 1, a rnbbin g-roller covered with leather may be used in connection with each of the traveling aprons F F, for the purpose of rubbing or rolling the slivers into rovin gs. This modification is represented in Fig. 2 of the drawings, in which It It are the rubbing rollers, which receive rotatory motion, and also reciprocating motion, in the direction of their axes, the roller R working in connection with the endless traveling apron F, and the roller R in connection with the endless traveling apron F. b 1), Figs. 1 and 2, are small rollers, which revolve in contact with the endless aprons F F, respectively; the object of the said rollers being to press against the said endless aprons the small slivers of wool or other fiber, as they move onward in a divided state from the ends of the steel strips or blades d d, and also to cleanse the ends of the said strips (1 d, which are bent so as to hook onto the bar T, as shown,

a small space or interval being left between the said strips d d and the face of the said bar T, so as to prevent the fiber from catching or being arrested on the ends of the said strips.

The working of the apparatus is as follows: The endless traveling aprons F F having been suitably greased and rubbed, the sheet or web of wool or other fibrous material a from the dofi'er is made to engage between them, as shown, Fig. 1. The said sheet of fiber is drawn on by the motion of the said aprons F F, and the adherence of the said sheet of fiber to the leather aprons F F is such that, instead'of its advancing motion being arrested when it comes in contact with the steel strips 61 d as they cross each other between the said aprons, the said sheet or web of fiber separates, or is divided into two series of slivers, which sliversadhere alternately to the upper and to the lower endless apron or band, and follow the directions indicated by the letters d cl d d, Fig. 2;;and the said slivers, stilL adhering to the leather: aprons- F F, the rubbers It R, wherethey are rubbed or rolled into rovings, which rov-ings are then wound onto bobbins: S S S S, Fig. 1, of which there'may. be one or more for each endless:

apron F F according to the number of rovin gs. A, single pair of dividing rollers, covered with, leather, may be substituted for the endless:

rubbing-aprons F F hereinbefore, described, a rubbing-roller being used in connection with ment is shown in section in Fig. 4,,where: it will be seen that the rubbing-rollers are placed aboveiand-below the dividingrollers, respectively. Or the sheet or web of fiber maybe divided into slivers between two dividing-rollers, and the slivers-rubbed into rovingsby ordinary rubbers, asshown at Fig. 5.

Figs. 6, 7, 8, and 9; illustrateanother arrangement, of my apparatus, in which; the: cross-- barsV. V are dispensed with, and the steel stripsv or bladesd d are attached by one end only to the cross-bar-T, which; is placed on the delivery side of the dividing-.aprons-F F. In: thiscase the said strips or blades. 01 d. are solderedto. smallpieces'of iron bent and curved so asta cause the said'strips to rest upon the dividing-aprons, the said stri-ps being curved and bent backward, as shown at Fig. 7. The

said strips d: d, thus formed, are placedside by side, asseenat Fig. 8,which:is a plan-viewviding-aprons. :in the arrangements hereinbefore described respectively, pass under of some of the strips and part of the cross-bar T; and Fig. 9, which is an elevation of the said strips and part of the dividing-aprons, viewed from the front side of the apparatus. The object of this arrangement is twofold first, it enables the strips d d to be made more resisting on that side where the sheet of fiber is fed between the aprons and secondly, it prevents the small particles of fibrous material which pass along the sides of the blades or strips from being arrested, one by the other, and collecting on the delivery side of the apron, and. then,if not carefully removed, falling onto the rovings and becoming attached thereto.

By having the ends of the steel strips turned back the small particles of material arrested between the adjoining strips or blades are pressed upon, and carriedforward by, the di- This resultmay also be obtained with reference to Figs. 1 2 3 4 5, by adding to each of the dividing blades or strips a small blade or strip curved in an: opposite direction, as shown at Fig. .10.

The peculiar shape of the blades'or strips 61 d, (represented in Figs. 6, 7, 8, and 9-,) has also the advantage of allowing the rollers b b to be placed quitev close to the ends of the said blades or strips d d, so as to cleanse them from the grease which is alwa s accumulating on their ends when highly-lubricated fibrous 3 material is operated upon. each of the said dividin g-rollers.

Having now described my invention,- and the manner of performing thesame, Iwish it sljObG understood-that I do not confine myself to-the precise details hereinbefore described,

and illustrated in-the accompanying drawings,

as the same may be varied withoutdeparting from the-nature of my invention.

Having thus fully described my invention,
