IMPROVEMENT 4MACHINES FR RAISING THE NAP UPON CLOTH.

To wHoM IT MAY coNcnRN:

Beit known that I, ANTON ZSCHILLE, of Grossenhain, in lthe kingdom of Saxony, have invented certainV new and useful improvements in Machines for Raising theNap upon Cloth, technically termed Grigs;\and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, wherein I have represented the machine at one-fifth of its full size,'thc letters of rei'crences, as well as the coloring-corresponding for like' parts. v

In Figure 3 I have shown my' improved cross-gig applied for operation in connection with au ordinary or suitable finishing In this instance the outlines of a double cylinder gig are shown vin dotted lines, and for convenience sake the draught roller'w is located in the lower part of the frame, z'. el, as near as practicable to the stretcher beam e. The red line represents the cloth. The cross-gig may be used independently of Vor in connection with a single or double cylinder gig, in which both the cloth and the teazlesv move continuously in the direction of the ualnap. I

The objectof Athis invention is to more eil'ectually'and evenly-raise the nap on theV surface of the cloth by `thec'omhined longitudinal ortransversal teazling. In ordinary gigs the nap is formed by the continuous action oi' the teazles in but one directiOng. and the nap thus raised is irregular, according to the unevenness in the cloth and the teazle surface. This is more apparent when, from some .cause or other, .folds or creases occur in the cloth, the 'effect of which is that while in some places the cloth is teaz'lcd through so as to impair its quality, in other parts the cloth remains entirely unacted upon. lBut the great advantage attending the use of my improved cross-gig is that the Work of teazling is elected in'oue-third of the time usually employed, aud that theteazling across the path of the cloth more thoroughly raises the nap.

The cross-gig` is established in au' upright frame iu suitable brackets, iu which are mounted two vertical rock-shafts, d, one on cach side of the machine. To these rock-shafts, and by means of cranks, are attached the two rollers :v and gl, and the stretcher beam ci, which hold the cloth in its proper relation and tension against the teazlefplates. The rock-.shafts are provided at their upper ends with hellecrauks, e, which are coupled ny means of a right and left-haud screw L, working in corresponding nuts on the longer arms of the bell-cranks, so that by turning the handlev of the said right and left-hand screw, the rollers and beam, :v y and z, are moved either to or from the plane of teazliug. This arrangement is shown more particularly in the plan view, Figure 2. Fdr thenicer adjustment of the cloth, the bell-cranks, instead of terminating in a nut, may be formed at v their ends into a toothed segment, which engages in the thread of the screw, as shown at tig. 2, bis. f The teazling mechanism or surface is composedz of detached, independently moving,'ilat and cellular plates, in which the teazlesare-inserted; and it has this peculiar mechanical disposition, that each plate while constantly parallel to the surface of the cloth, moves inan arc of a circle, or, according to an ellipse, hymeans ol' an arrangement of craulrs, eccentrics, or other equivalent means. In preferencqfour or six teazle-plates are used, in which the Vtcuzles are inserted, with their points turned towards the side of the machine nearest them, iu order that the cloth, as it travels by the teazles, may be alternately teazled from its middle towards its sides. Thus the four teazle-plates will alternately and in opposite directions advance, traverse the surface of the cloth from the middle toward the sides, and ,then recede therefrom, This movement is effected bymeans of double eccentrico mounted on verticalshafts, which a're moved by suitable gear mechanism from a sha-ft, l).

'In Figure ,11 have 4,shown one of the skeleton teazle-plates." It is carried by means of two eccentrica, shown in Figure 8or by means of' a crank-shaft, as shown inFignres I2-and 13. In the former case a yoke or hoop (Figure 9) is used to embrace the eccentric; iu the latter boxes are used, as shown in perspective in Figure 14. In both cases, however, the plate is let in and secured to the slide s e', which is attached, to the yoke, as seen in Figures 10 and 12.. By this means the teazle-plate may be conveniently inserted from the side, and held in Vplace by a spring latch, f. The eccentries or cranks are so mounted or arranged on the vertical shafts e, that the action of the vteazle-plates shall be the same in 'each-pair, and so that the vertical series of plates, on cach side of the middleof the cloth, shall successively, and not simultaneously, come In contact with the cloth, thus' 4allowing each plate to have full sweep over the surface upon which it is required to act.

In Figure 3 three pairs of plates are shown, and the position of the vertical series of plates is clearly seen,

the top plate being in contact Withthe cloth, the middle plate being still some distance therefrom, while the third or bottom plate is at its aphelion, so to speak', or at the furthest point it can be from the cloth.

In Figure 4, where' only two pairs of plates are shown, I prefer to use a roller, a', intermediate between the two pairs, which s erves to hold the cloth in proper position. The relative position to each other of the eeeen trics of'the three pairs of plates, iig. 3, is shown in Figur/e 6, and the position of the two pairs in fig relatively to each other, is seen in Figure 7. There may be att-ached to both the right andleft teazling plates slides, z'z', with projecting jaws, k, Figures 15 and 16, (see also Figure 5,) which, by means ofthe nose, Z, andthe i two plates -constituting the pair being united by the connecting-rods it, impart to the eccentries an increased sliding motion, which will result in an elliptical motion.

This machine is driven from a prime mover by aband passing, as shown in figs. 1 and 3, from a main pulley or driver over the pulleys B and Blz-the former being loose and the latter fast.' These pulleys are mounted on the main driving-shaft D, upon which are mount-ed bevelled gear-wheels which mesh with correspondingr bevelled gear en the upright shafts E which-carry the ecccntrics. I prefer torun the gig at a" speed giving from 120 tov 150 revolutions per minute. In order to prevent the teazle-platcs from moving inversely, I use a ratchet-wheeland pawl, C, which will ride overthe teeth of the wheel as long as the main shaft of the maehinerev'lves in the proper direction, but will stopthe motion, if it be attempted to move it in the'opposite direction. In conelusion, I would observe that it is'preferablenot to use the machine either at the commencement or finishing of the teazling operation. I

Having thus described my invention,\vl1at I claim, and desire to secure byLetters Patent, is

1. I claim a gig or machine for raising the nap on cloth,'eomposed of the following elements: first, a mechanism for moving the cloth through the machine so as to present plane surfaces to the action of the t'eazles; second, one, two, ormore p'airs of plane-surfaced, independent teazle-plates, witlrmechanisin for moving the same while maintaining their parallelism with the cloth, in arcs of a circle er otherwisefso that each plate shall 'continuously movetoward the cloth, sweep transversely andin contact Awith the cloth from the centre toward the sides thereof, then recede and return towards the centre. i

2. I also claim the means herein-described for engaging or disengaging the cloth with or from the' teazle` plates, and regulating their pressure of Contact, substantially as shown and set forth.

3. I also claim the method of teazling cloth rby machinery, substantially :is herein showntand described;

that is to say, by imparting to the teuzling surfaces the following motions, viz, to and from the.cloth, and also at right angles to the run thereof,'so that the nap shall be raised crosswise from the centre, or thcreabouts, to

the sidc's as described. K

In testimony whereof I have signed my name to this Ispecification before two subscribing witnesses.

hmmm, this 13th day of December, 1865.
