MACHINE FOR BRUSHING AND NAPPING FABRICS.

SPECIFICATION forming part of Letters Patent No. 406,187, dated July 2, 1889.

pp at n fil September 25, 1888- Serial No. 286,325. (No model.) Patented in England December 13, 1887, No. 17,143 in France August 18, 1888, No.192,479, and in Germany August 30, 1888, No. 46,847.

To all whom it may concern:

Beit known that we, JAMES WoRRALL, of Ordsall, Salford, in the county of Lancaster, England, and JOHN KERSHAW, of Hebden Bridge, in the county of York, England, have invented certain new and useful Improvements in Machines for Brushing and Napping Fabrics, (for which we have obtained Letters Patent of Great Britain, No. 17,143, dated December 13, 1887; brevet dinvention of the Republic of France, No. 192,47 9, dated August 18, 1888, and patent of the Empire of Germany, No. 46,347, dated August 30, 1888,) of which the following is a specification.

This invention relates chiefly to the finishing of cords, moleskins, and velveteens; but it is also applicable to the treatment of other fabrics in Which a nap is required to be raised on the same.

In finishing corduroys it has been usual to subject the cut-pile fabric, as it is passed through the finishing-machine, to the action of reciprocating brushes or endless chains of brushes working transversely of the machine, and at right angles to the travel of the fabric. Great difficulty has, however, been found in insuring that the brushes shall penetrate to the bottom of the pile, or that they shall act uniformly on the whole breadth of the fabric.

Now the main object of the present invention is to obtain a uniform action of the brushes over the surface of the fabric, and that of a more searching character than heretofore.

To this end We construct the finishing-machine in such a manner that the cord or other fabric will be fed into the machine at the side thereof, instead of at the front end, as heretofore, and received onto the rounded edge of a diagonal bed or bar stretching from side to side of the machine. Over this bed the fabric is drawn by a suitable card-roller, and it is delivered out of the machine at the back end thereof. In front of this diagonal bed we mount a rotary brush, the tufts of which are helically disposed in the usual manner aroun'd its periphery. To this brush we give fabric will be laid bare as it passes over the edge of the bed. No obstacle will therefore be presented to the penetration of the brush into the pile, and hence the brushing will be rendered far more efficient than heretofore.

WVhen it is desired to raise a nap on the fabric, a card-roller is substituted for the rotary brush.

In the accompanying drawings, Figure 1 shows in plan view our improved machine fitted as a finishing-machine, say, for brushing cords; and Fig. 2 is a front view of'the same, the bars which guide the cloth into the machine being removed, the better to illustrate the construction and posit-ion of the working parts. Fig. 3 shows in front view the guide-bars mounted on the framing of the machine, together with a guide-roller for receiving the cloth from the bars, and Fig. 4 is an end elevation of the same. Figs. 5, 6, and 7 are detached views illustrating the arrangement of the diagonal bed or bar over which the cloth travels and the parts in immediate connection therewith for brushing the cloth, and for insuring that the cloth shall retain its proper position while passing over the bar.

A A are the side frames of the machine, held-together by tie-rods and furnished with bearings for the main driving-shaft B.

C O are light standards mounted on a lateral extension of the frame A and carrying guide-bars c c 0 0 the position of the standards being such that the guide-bars will lie askew, or at about an angle of thirty degrees with the side frame A. To thelateral extension of this side frame bracket-bearings are bolted to carry a guide-roller D, which is fitted with a friction-pulley (Z, operated upon by a brake-band 0, passing about the pulley and maintained tautbyaweight p. The frictionpulley will retard the tendency of the roller to rotate under the draft of the cloth that is submitted to the action of the machine.

E is a diagonal bed or bar made fast by brackets to the side frames A A. This bar, which lies at an angle to the frame A corresponding to the angle made by the guide bars with that frame, serves to present the cloth to the action of the rotary finishing brush F, which is mounted in bearings at tached to the side frames, the bracket of the side frame A being the same as that which carries the front end of the diagonal bar. This same bracket also carries a bearing for a short smoothing-roller G, which underlies the bar E and is supported at its farther end in a bearing carried by the bar.

If is a roller for drawing the cloth over the diagonal bar, whence the cloth passes under a guide-roller 7i and up to a roller I, which delivers it to the ordinary reciprocating folder K.

The cloth to be treated is brought in a pile to the side of the machine and laid alternately over and under the guide-bars c c 0 0 as shown in Fig. 4. It then passes under the guide-roller D to the under side of the diagonal bed or bar E, and, being laid over the edge thereof, it is brought up to the drawingroller Iil, whence it passes, as already stated, under the roller 72, and thence to the folder.

The driving-shaft B is fitted with fast and loose band-pulleys I), through which it receives its motion. It is also fitted with a band-pub ley b and a double-grooved band-pulley b for transmitting motion to the operating parts of the mechanism. A crossed band from the pulley 1) passes round a pulley 71 running loosely on the shaft of the roller ll. Cast in one with this pulleyis a spur-pinion h ,whieh gears into a spur-wheel 7L3, keyed to a trans verse axle 71f, carried by bearings on the side frames A A. To the opposite end of this axle is keyed a spur-pinion Zr, gearing into a spuravheel 72 which is keyed to the axle of the roller ll. This arrangement of gearing serves to transmit from the quickly-rotating driving-shaft 15 a slow rotary motion to the roller IT, for the purpose of drawing the cloth into and through the machine.

Keyed to the front end of the axle of the brush F is a band-pulley f, which receives a band from the double-grooved pulley b in the following manner.

f f are guide-pulleys mounted on studs of the side frame A, and f is an adjustable tension-pulley carried by a stud, which is adj ustable by hand in a longitudinal slot f in the frame A, and secured in position by any suit able clamping device-*such, for instance, as a nut. A band from the pulley 1) passes under the guide-pulley f, then up to and over the pulley f, down to and under the guidepulley f and thence to the second groove of the pulley b From this pulley the band passes forward to the tension-pulley and back to the pulley b Thus provision is made for the band to accommodate itself to the skewed position of the brush-shaft. On the opposite end of the brush-shaft is keyed a worm f which serves to drive a worm-wheel g, carried by a short shaft that has its bearings on the bracket that connects with the frame A and carries the brush-shaft.

g is a grooved pulley on the worm-wheel shaft, and from it passes a band which leads to a pair of grooved pulleys g carried by an adjustable stud connected to a standard supported on the near bearing of the brush-shaft. The said stud is adjustable by hand in alongitudinal slot g in said standard, and maybe secured in any desired position by a suitable clamping device-such, for instance, as anut. From these pulleys the band passes down to and is laid around a grooved pulley on the axle of the s1noothing-roller G. Thus a slow rotary motion is imparted to the roller G as the cloth is drawn into the machine. This roller is ribbed longitudinally, and it serves to counteract a tendency which the cloth has to shift on the diagonal bar E away from the feeding side of the machine. A slow rotary motion is given to the delivery-roller l by a band which passes from a pulley 7L7 on the shaft of the roller ll to a pulley i on the shaft of the roller I. The folding apparatus K receives its reciprocatin g motion from the crank 7c of a transverse shaft which is driven by a band from the roller 1.

It will now be understood that when corded cloth is presented to the action of the brush F the bristles will, by reason of the opening of the pile, be able to penetrate the sides of the cords and act upon the whole length of the pile.

To adapt the machine to the raising of a pile for the manufacture of mole-skins, it is only necessary to substitute for the brush Fa card-roller of any approved construction. \Vhen the card-roller is used in this machine, a fuller nap is raised (owing to its diagonal action on the cloth) than if it acted longitudinally of the cloth, and, as compared with cross-raising, its action is far more rapid. The nap may be raised on one or both sides of the fabric, but when required to be raised on the back the fabric will in that case be laid into the machine so that its back shall be presented to the action of the card-roller.

It willbe understood that the length of the brush and of the carding-roller will somewhat exceed the measured width of the fab ric as presented to the edge of the diagonal bed.

Having now particularly described and as eertained the nature of our said invention and in what manner the same is to be per formed, we declare that what we claim is-- ITO 1.
