- SPECIFICATION forming part of Letters Patent No. 406,326, dated July 2, 1889.

Application filed March 10, 188.

To all whom it may concern.-

- a machine by which fabrics can be thoroughly and quickly gigged, and by which an even nap can be raised upon the goods, as fully described hereinafter, reference bein had to the accompanying drawings, in which- Figure 1 is a side view of my improved gigging-machine. Fig. 2 is a transverse section on the line 1' 2, Fig, 3, parts being in elevation. Fig. 3 is a plan view. Fig. at is a View of one of the simplest forms of my device. Fig. 5 is a view of the machine'by which the fabric is gigged on both sides as it passes through the machine. Figs. 6 and 7 are views showing details of construction, and Fig.8 is a view of a modification.

A is the frame of the machine, and L is the main driving-shaft.

D D are two rollers mounted in suitable bearings (Z (Z, secured to the frame of the machine.

E is a feed-roller mounted in bearings in the frame of the machine and covered with fine teeth to feed the cloth through the machine, said roller being provided with a chainwheel 6, geared to a chain-wheel b on a supplementary shaft B by a chain F passing around these chain-wheels and driving the roller E from the said shaft.

G G Gr are three small rollers adapted to bearings in brackets g, vertically adjustable on the frame A, set-screws g, which pass through slots in these bracket-s, securing the brackets in the position to which they are adjusted.

H H H are three stationary cross-bars, the bars 11 being padded on one side and the bar H padded on both sides, as shown in Fig. 2 for a purpose described hereinafter.

On each side of the machine is a lever I, pivoted. in bearings i on the frame of the machine. To these levers are attached crossbars J J, having on each side gigging-teethj, which engage with the cloth as the frame is ably faster than the travel of the cloth.

reciprocated. The frame is reciprocated by means of eccentrics K, near the ends of the shaft L, the strap of the eccentrics being connected to pins 2" on the-levers I. The shaft B is driven from the main shaft L through the medium of the pinion Z and a large gearwheel 0, as shown in Figs. 2 and 3, so that the frame formed by the levers I and cross-bars J Will be reciprocated at a speed consider- The cloth passes over a bar a and under a guideroller 1%. The bar a is provided with a roughened surface, for the purpose of placing tension upon the fabric as it passes through the machine. I

The cloth is represented in the drawings by the two light lines at, and is fed into the machine in the direction of the arrows, Fig. 2, and it will be not-iced that the cloth first passes over the bar it, under the roller m over one of the rollers G, down between one of the padded bars II and a gigging-bar J, around one of the rollers D and up between the bar H and a gigging-bar, and over another roller G, and so on, as indicated, until it passes under the roller E, which is the feed-roll of the machine. This feed-roller draws the cloth through the machine, keeping tension upon the cloth at all times while it is passing the giggingframe. The cloth then passes up to and over a roller M, mounted on a bracket on the frame of the machine, this roller M being driven from the roller E by means of a belt M; As the cloth passes from the roller E to the roller M, it is brought into contact with a revolving gigging-brush N, preferably driven at a higher speed than the roller E, and being also preferably driven from the shaft L by means of a belt N.

P is an inclined board at the rear of the machine, which guides the material to the front of the machine after it passes over the roller M.

If necessary, the material can be passed through the machine several times, the num- 9 her of gigging operations to which it is subjected depending greatly upon the character of the goods operated upon.

In some cases the multiple gigging-frame may be dispensed with, and a frame may be used, as shown in Fig. 4, in which the gig is placed between two stationary bars H H, and instead of being positively mounted on the frame can slide thereon, the eccentric giving practically the same movement to the gig, and the fabric in this instance being gigged only twice in its passage through the machine, whereas in the machine shown in Fig. 2 the cloth is gigged four times.

In Fig. 5 I have shown a single roller G and a single feed-roller E, and the cloth, as it passes through the machine, is gigged on both sides, the two giggin g-bars J J being mounted upon the arm I, one on one side of the bar II and the other 011 the opposite side of another bar H, so that the cloth passes between the two stationary bars and the two gigging-bars, being gigged first on one side and then on the other. This device may be duplicated, if found necessary. By this method of gigging the cloth itself engages with the teeth of the gigging-bars and not as is usual in this class of machines, in which the teeth have a movement to engage with the cloth. The cloth moves slowly through the machine, and as the gigging-teeth strike the cloth, the cloth continues its movement and engages with the teeth, and as the teeth pass away from the cloth they drag with them a port-ion of the fabric and form a nap thereon.

As shown in Figs. 6 and 7, I preferably fix the gigging-bars J to their frames or levers I in such a manner that either set of giggingteeth on said bars can be brought into use,

the gigging-teeth being placed on all four sides of the bars, so that when two sets of teeth sets of teeth will engage with the cloth, the

bar being secured in position by tightening the bolts forming its axis, thus providing for the continuous operation of the machine without stopping to replace the bars with new or cleaned teeth.

I prefer to use as teeth fine card-clothing, and this clothing is mounted upon strips 8, which'are secured to the bar by means of screws s,as shown in Fig. 7 ,so that the strips can be readily removed and new strips inserted.

The gigging-bars .I may be round, as shown in Fig. 8, or many-sided instead of square, as shown in Fig. 7, so that as the teeth become clogged a new toothed surface may be presented by simply turning the bar J, as before remarked in reference to Fig. 6.

The frames or levers I, on which the bars .I are mounted, I prefer to slot longitudinally, (see Fig. 6,) so that the bars may be adjusted to or from the stationary bars H.

I prefer to pad the bars II; but in some instances the padding may be dispensed with, this padding depending, to a great extent, upon the quality and thickness of the goods operated on.

I claim as my invention 1. The combination, in a gigging-machine, of a reciprocating frame carrying one or more gigging-bars with teeth upon their opposite sides, opposite padded backing-bars, and means for reciprocating said gigging-bars between the backing-bars, with feeding devices for carrying the cloth to be gigged through the machine, substantially as specifled.

2. The combination, in a gigging-machine, of one or more stationary backing-bars, the reciprocating frame carrying one or more transverse bars of round or rectangular crosssection, said bars being provided with reserve gigging-teeth capable of adjustment to working position, means for reciprocating said frame, and feeding devices for carrying the cloth to be gigged through the machine, sultst-antially as specified.

3. The combination, in a gigging-machine, of the stationary bars II II, guiding-rollers G and D, and the feed-roller E with a reciprocati n g gigging-frame having cross-bars J and teeth on the sides of the cross-bars opposite the stationary bars II II, with means for reciprocating the gigging-bar, all substantially as set forth.

4. The combination, in a gigging-machine, of the gigging-frame composed of bars II II and the reciprocating giggingframe, the guiding-rollers, and feed-rollers with a brush N, situated in the rear of the gigging-frame, and means to reciprocate said gigging-frame, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHRISTIAN \VOELFEL.
