TO ALL WHOM I'l MAY CONCERN:

Be it known that I, WILLIAM CLISSOLD, of Dndbridge Works, near Stroud, in the county of' Gloucester, engineer, have invented Improved Machinery for Feeding Wool and other Fibres to Preparing and Carding lll'achinesg and I do hereby declare that the following is a full and exact description of my said invention.

The object of this invention is te provide a means of feeding wool, cotton, or other? fibrous substances to preparing or carding machines without separating t-helong from the short fibres. Thus, whenl operating with -wool I propose to make a but or sheet with the long and short Wool or shoddy well. mixed, and of the same eonsistence throughout itsbreadth and length. The wool or other` fibre to be operated upon is placed in a large box or receiver of the width of the bat or sheet required to be made, the width being determined by thc width ol` the machine to be fed, and by means of reciprocating-bars which form the bottom of the box it is propelled towards a horizontal opening cut in one end of the box, and corresponding i-n length to the width of the box. The continuous end way motion of the bars causes the wool to be discharged through the opening at a certain regulated .rn-te, the wool passing between a pair of reciprocating combs, which, acting upon the wool, masses it 'into a. continuous bat of' uniform thickness. In the' accompanying drawing- Figure 1 is an elevation of' the right side, and

Figure 2 an elevation of the left side of the feed-box, looking at it from the front.

Figure 3 is a longitudinal section of the feed-box; and

Figures 4 and 5 are respectively front and back elevations of' the same.

A is a rectangular open box for receiving the wool or other material to be delivered to the preparing or car-ding machine to be fed. The bottom of this box is formed of inclined bars B B, which are suspended at their upper ends by hooked rods C, pendent from a round cross-bar, Cl, at the back of' the box. The front and lower ends of the bars B extend to the front ofthe feed-box, and they are armed with steel terminations, B1, suitably shaped, as shown at fig. il, for-propelling the wool forwards. The box A has a horizontal opening, A1, at the level of the bars, through which the fibrous n'iatlprial is discharged. A forward endway motion is given alternately to every other ol" the bars by means of coiled springs Dwhich connect them with a fixed cross-bnr, Dl., and the return or back motion is producedby means of' fingers E, or it muy be on cams on a rotating transverse shaft, El, striking against bracket projections B2 on the under side of` the bars B. The object of this endway motion of' theinclined bars is to feed the overlying fibre towards the horizontal opening in the front of' the box and bring it under the operation of a pairot1 horizontal reciprocating combs or toothed bars, F, which are intended to mass it, as it is discharged from the box, into a loose, thick sheet or but. The quantity of' bre discharged is ganged by the depth of' the horizontal opening or mouth A1. The shaft El, carrying the fingers E, receives motion through spur-gearing from another transverse shaft, G, which is fitted at its ends with a pair of' eccentrics, (or it may be eranks,) Gl, for operating, through coupling-rods G2, a pair of cranked levers, H, situate one on cach side of' the feed-box. These crank-rods are formed with segment racks H1 at their outer ends for the purpose` of' gearing into and driving a pair of racks, Fl, attached to the comb-bars F. -These comb or toothed bars slide up and down in inclined guides fitted to the front of the feed-box A, an inclina-tion being' given to them to allow each comb-bar to pass the teeth of' the other as it is propelled forward. The con1b-bars being thus actuated by the segmcnt-mcks through the agency of the cam-shaft and rock-levers above mentioned, they are caused alternately to act upon the fibre, giving it at the .same time a slow forward motion, which motion allows of the fibres before they escape from the teetheaecumulating sulicien-tly to form a thick, even bat. The inclined bars 13, forming the bottom of the feed-box, as they are drawn back leave vacancies at their forward ends into which the fibre passes, andthe tendency of' the fibre as it accumulates near the discharge opening A1 to move back at thc return motion of' the bars isucounteracted by means of' loose rods K which are pendent from a cross-shaft, L, but which are at times free to drop and bear upon the wool with their whole weight, thereby pressing it down for the ends of the bars to thrust it into the discharge opening of' the feed and pre= venting the back motion of the bars disturbing the fibre. This cross-shaft L, which lifts the bars at the proper moment for relieving the fibre of their pressure, is carried by a pair of .rock-levers, M, which are mounted on a. cross-shaft, M1, having its bearings in the sides ofthe box A. From the extremity of one of the levers depends a rod, N, carrying at its lower end a wedge-shaped elastic projection, N1. A pin or projection on a disk, 0, keyed to the shaft E, in its rotation strikes against the .elastic projection on the rod N, and therehr gives a. reciprocating motion to the rock-levers M, causing them to lift the rod L, and with it the pressers K. The continuous rotation of the dish causes the elastic projection to yield to the pressure of the disk-pin, and the rod being now released the roch-levers will resume their former position and allow the rods K to press again upon the wool. The massed bre or bat as it leeres the combs is passed between 1L pair of pressing-rolls, P P, which will serve to deliver it to the aprons, feeder-011s, or cylinders'of the preparing or other machines. This arrangement ofv machinery will deliver the fibre in uniform quantity so long as there is suhcient fibre in the be); to fill the discharge month or opening, and thus the production of even la-ps may be insured in the subscquent processes of manufacture.

Having now set forth the nature of my invent-ion of improved machinery for feeding Wool and other fibres to preparing and carding machines, and explained the manner of carrying the same into effect, I Wish it to be understood that I claiml. The combination, with the inclined reciproonting-bnrs B, of the reeiproentingcoinh bnrs F, and rods or pressers K, for the purpose of discharging the wool or other brons material from the feeding-box.

2. The combination, with the reciprocntingcomb bars, of pressing-rolls P for delivering the wool or other fibrous materiel to the preparing machine in the form of a. bfi-t or sheet.

In witness whereof` I, the said VILLIAM CLISSOLD, have hereunto set my hand and seal the twelfth day of November, in the year of` our Lord one thousand eight hundred and sixty-six.

i Signed, sealed, and delivered by the above-named VILLIAM CLrsSoLD in the presence of -WLLLIifvI GLSSOLD. [L s] Witnesses:

ARTHUR H. WANsEY, N, P., Bristol. G-rLns H. WHITTAN, 7121s Clerk.
