MACHINE FOR NAPPING TEXTILE FABRICS.

SPECIFICATION forming part of Letters Patent No. 393,605, datedv November 2'7, 1888.

Application filed March 30, 1888. Serial No. 269.026. (No model.) Patented in France September 26, 1887, No. 186.067, and

in England March 16, 188B, No. 4,102.

To a/ZZ whom t may concern,.-

Be it known that we, GUSTAVE BAUCHE and HENRI BAUOHE, citizens of France, residing at Rheims, in the Department of the 'Marne, France, have invented a new and useful Improvement in Machines for Napping Textile Fabrics, (for which we have obtained French Patent N o. 186,067 dated September 26, 1887, and English Patent No. 4,102, dated March 16, 1888,) of which the following is a specification.

This invention relates to machinery for napping (forming or raising a pile or nap on) all sorts of fabrics of wool, cotton, or other textile materials. It enables the rough action of the ordinary cards or metal teazles to be avoided,

.and insures a very regular working in which" the fabrics are not broken, whatever may be their character, their lightness, or their power of resistance.

In the accompanying drawings, Figure 1 is a view in elevation with one of the side frames removed of a napping-machine containing the present improvements. Fig. 2 is an end view partly in section; Fig. 3, an edge view of the parts in which the invention principally resides, and Fig. 4. is a detail view.

The cards l, termed workers, are placed in revolving carriers, of which four (lettered B', B2, B3, and B4) are shown. VThey are arranged in series of three to each carrier; but their number, as also the number of carriers, can be increased or diminished at will. Each worker 1 is journaled in bearings in the heads ofthe appropriate carrier. The carriers are journaled in bearings in the side frames of the machine and are driven byany ordinary or Suitable gearing (belts,for example)-which is not shown, as it forms no part of the invention and can be applied by any competent mechanic.

The fabric to be napped is represented by the broken line a, and is drawn in the direction of the arrows, passing over the guiderollers b b' b", and being by them held in proximity to the carriers B' B2 B3 B4 of the workers. The means employed to feed the fabric and keep it stretched are not material to the invention. suitable description. As shown, however, there is a wooden roller, l?, over which the fabric a is drawn, and it is provided with a They'may be of any known or' brake in the form of a leather strap, P',which can be tightened or loosened by means of the screw B and its nut, so as to increase or diminish the tension on the stuff.

Q is a toothed wheel at the end of a shaft, Q', which carries a rod, V, at the ends of the arms V', and there is a pawl, S, which engages the wheel Q and holds the shaft Q and rod V stationary. The fabric is drawn around the rod V and a roller on the shaft Q', and by adjusting the position of the rod V, which is effected by releasing the pawl S and turning the wheel Q, the tension which is exerted on the fabric can can be regulated.

J H are the drawing or feed rollers, and F a pressureeroller, all of which are or may be of ordinary construction and operation. The drawing or feed rollers deliver the fabric to a vibratory arm, M', (as common in similar mechanism,) for laying the fabric in folds, and this arm M' is reciprocated by a crank-wheel, O, through a pitman, M.

As shown, the roller J is driven from a beltwheel, 15, through a Spurgear, 16, rotating with said belt-wheel and meshing with the spur-gear 17 on .the roller J, and the roller H is driven by frictional contact with roller J.

The fabric to be napped is first acted upon by the workers or cards 1 on one side of the carrier B'. Then it descends on the other side of the same carrier, to be acted upon a second time by the same set of cards. It is then acted upon in succession by the workers or cards 1 of the carriers B2, B3., and B4, all the carriers being rotated, as before described, and carrying around with them their respective workers 1, so as to draw them successively over the fabric. It is in the mounting of these Workers on their carriers that the invention mainly resides.

Referring to Figs. 2, 3, and 4, the axles A of the workers or carding-drums have pillow blocks or bearings 2 combined with springs K, which force the blocks or bearings against the axles, so as to givea yielding resist-ance to the rotation of the workers. These springs, which are by preference leaf-springs in the form of endless bands, curved as shown-one for each end of the carrierfsurrounding the axis of said carrier and forming 'an elastic support common to all the journals, as shown in the IOO drawings, perform their function by giving way to the resistance of the fabric in contact with the metal cards of the workers, which engage the stuff to be napped solely by virtue of the elastic force of the said springs, a force which can be varied according to the fabric treated. The workers thus form yielding carding-drunis, which can be rotated on their own axesby the contact with the fabric to benapped. The blocks 3 are out of contact with the blocks 2, so as not to prevent the latter from being pressed against the axles by the springs K,and they are confined by the plates 6, fastened by screws to the circular head ofthe carrier. In this outer block is or may be formed a lubricant-chamber, 9, iu the bottom of which cotton may be placed. Two conduits, 10, extend from this chamber or reservoir 9 to the axle A of the worker. The inner block, 2, has a screw-threaded stud, 5, on which is screwed the nut 4, that rests on the spring K. The nuts 4 have teeth or cogs on their peripheries,

and those at the same end of each set of worki ers are engaged by the gear 7, so that by turning said gear to the right or left each nut will be screwed off or on its stud 5, and the tension of the spring K consequently increased or diminished.

The pressure with which the block 2is held against the axle A varies, of course, with the tension of the spring K and permits the worker to turn with greater or less freedom; or, in other words, the eifect of the brake on the worker is changed as may be required. The metal teeth of the cards will penetrate into the fabric, more or less, according to the resistance offered, without permitting the said fabric to be torn.

rllhe gear 7 can most easily be turned by a pin inserted into' one of the holes 8. (Shown in Fig. 3.)

At the moment when, by the rotation of the carriers B B2 B3 B", a worker, 1, comes into contact with the fabric it is subjected, by reason of such contact, to a pressure which tends to bend the spring, so that the working-teeth act upon the material only to the extent required to nap without injuring the fabric. It will, of course, be understood that by increasing or diminishing the tension of the springs K, by turning` the gears 7 in one direction or the other, the .fabric or stuff may be acted upon more or less strongly, the braking action, due to the friction of the axles A in their boxes or bearings, being lgreater or less. The yielding or elastic and adjustable suspension of the workers by their axles is thus a very important improvement,since it permits a regulated working for all kinds of stuff or material.

The new or improved system of contact demands-or at least it is most usefulthat there should be in connect-ion with it a means of regulating with great precision the contact of the workers with the fabric. To provide such a means the following arrangement has been devised:

Referring to Fig. l, slides E E are supported in ways or guides D on each side of the machine-frame and adjusted simultaneously in opposite directions by means ofthe pinion D, meshing with the racks L L on the ends of said slides. These slides carry the fabricguides (the rollers b b, supported by brackets c c on the slides E E, as shown) over which the fabric is stretched when acted ou by the workers, so that by moving the slides E Il the said fabric is adjusted simultaneously toward or away from the workers 1. The guides 1/ on one side of the carriers B B2 B3B are movable with the slide E, and the guides b on the opposite side are movable with the slide E', so that all the guides move toward or away from the workers l, according to the direction in which the pinion D is turned.

In the drawings the yielding or elastic support for the workers or napping-cylinders is formed on each carrier B Bz B B4 of a single spring at each end of the carrier. The invention is, however, not limited to the use of a single spring, although this constitutes a special feature of our i nvention; but it includes the use of the elastic or yielding supports generally, irrespective of the number and arrangement of the springs or the precise mechanical expedient employed.

Ve claiml. In a napping-machine, a rotatory carrier provided with yielding or elastic bearings for the working or napping cylinders thereon, and having such cylinders journaled in said bearings and rotated by contact with the fabric to be napped, substantially as described.

2. In a napping-machine, a rotating carrier provided with yielding or elastic bearings and brakes for the working or napping cylinders thereon, and having such cylinders j ournaled in and acted on by said bearings and brakes, said cylinders being rotated by contact with the fabric against the yielding resistance due to the braking action, substantially as described.

3. In a napping-machine, and in combination with a set of workers or napping-cylinders rotated on their carrier by contact with the fabric and the rotating carrier for said cylinders, the bearings and brakes for said workers, composed of a confined block outside the axle of the worker, a movable block out of contact with the former and arranged on the opposite side of said axle, and a spring for pressing the movable block against the said axle, substantially as described.

et. In combination with a rotating carrier provided with divided boxes or bearings for the workers thereon, a set of workers having their axles journaled in said boxes or bearings, and a curved leaf-spring for each end of the carrier, in the form of an endless band surrounding tlie axis of the carrier and forming an elastic support common to the boxes of the set, substantially as described.
