MACHINE FOR BEETLING CLOTH.

SPECIFICATION forming part of Letters Patent No. 387,749, dated August 14, 1888.

Application filed December 1], 1983. Serial No. 114.927.

To aZZ whom it may concern.-

Be it known that 1, Duncan STEWART, a subject of the Queen of Great Britain and Ireland, residing at Glasgow, in the county of Lanai-k, Scotland, have invented certain Int proveiuents in Machines for Beetling (.lloth, (for which I have obtained a patent in Great Britain, dated August 10, 1881, No. 3,462,) of which the following is aspecification.

My invention consists of an improved machine for the beetling, calendering, or finishing of woven fabrics, felt, paper, or yarn, as hereinafter described.

For the better understanding of the manner of using my improved machine, I have shown in the accompanying drawings, and have hereinafter described, a number of accompanying devices which do not form any essential part of my present invention, for the latter relates only to the construction of the rotary beetlingcylinder itself.

Figurel n the aceompanyingshcet of drawings is a plan of the machinery, and Fig. 2 is a corresponding sectional elevation. Figs. 3 and 4 are enlarged sectional views of two modi fications of the spring-beetler.

My improved beetler is a shaft, 5, having on it a number of bands, 6, made of steel or other suitable elastic metal, bent each, as shown in Fig. 8, into a spiral (volute-shaped) coil, or in an analogous manner, as shown in Fig. 4. The bands or coils G are fixed to the shaft 5 by means of their inner ends, on which ends dovetail pieces are formed or welded, to be fastened by keys in dovetail sockets formed for them on a boss, 7, keyed on the shaft. The outer ends of the bands or coils 6 are free to move to a certain extent, and have rounded striking-pieces 8 formed or welded or otherwise fixed on them, and they are prevented from flying out too far through centrifugal action when rotating by stop-pins 9, fixed in disks or projecting plates 9, formed or fixed on the boss 7, these pins 9 acting on the extreme ends of the bands, as shown in Fig. 3, or on loops, as shown in Fig. 4. The bands 5 are placed on the shaft 5, so that their several ends are at difterent parts of the circle, and the shaft being made to rotate at a considerable speed in the direction of the arrows, the ends of the bands tend to fly out by cen- (No model.)

irifugal action, and in passing round strike the goods which are suliijectcd to them. The goods pass round a roller, it), placed parallel to the beetler shaft The beetler bands or springs (3 may be from two to four inches broad.

The action of the 'beetler is capable of being varied through a considerable range by varying the speed of rotation and the distance between the beetler-shaft 5 and the roller 10, on which the goods are supported while being operated on.

The beetler-shaft 5 and the roller 10 may be mounted and driven in the manner shown in the drawings. The parts are carried on a framing consisting of a pair of parallel side frames, 11, bolted down to a suitable foundation and connected by tie-rods 32, Figs. 1 and 2.

The beetler-shaft 5 is held in bearing-blocks 12, which are adjustable horizontally on the tops of the frames 11. The adjustment of both bearing-blocks 12 is effected simultaneously by means of a hand-wheel,13, on a small horizontal shaft, 14.,having on it worms 18in gear with worm-wheels 14: on screw-spindles 15, which act on the bearing-blocks. A'guard, 16, (not shown in Fig. 1,) is placed over the beetler-bands 6, to prevent anything from getting improperly into contact with them.

The beetler-shaft 5 has on one end of it fast and loose pulleys 17,for a driving-belt from an overhead shaft, and on the other end of it there is a pulley, 18, for a belt for driving a shaft, 19, below. A worm, 19, Fig. 1, on the low shaft 19, gears with a worm-wheel, 20, on a vertical shaft, 21, which, by means of bevelwheels 22, drives the roller 10, round which the fabrics pass while being acted on by the beetler. The low shaft 19 has also on it a small pulley, 23, for a belt, 23, which drives a grooved rollerfli. The grooves are arranged spirally and run in opposite directions from the center, so that as the roller turns it has the effect of breadthening or smoothing out the fabric as it is going upon the roller 10.

The fabric to be operated on passes round two other rollers, 25 26, besides the one 10 which presents it to the action of the beetler, the three rollers being at the angles of the triangle arranged so that the fabric incloses a space, 27, descending from the roller 10 to a roller,

25, beneath the flooring 33, thence proceed ing vertically upward to the third roller, 26, and returning downward again to the roller 10. The fabric is first entered from the inclosed space 27, and passing beneath breadthener'bars 28 and in contact with the breadthener-roller 24, hereinbefore referred to, proceeds round the outer side of the roller 10. The fabric is led round the three rollers 10, 25, and 26 two, three, or more times, so as to form as many plies or thicknesses on the roller 10, each part being in this way operated on several times, each time with fewer thicknesses outside of it, and receiving the final action of the beetler directly on it while having other thicknesses acting as a cushion under it. The

fabric finally passes round a guide-roller, 29, to swinging folding mechanism 30, of a wellknown kind, which deposits it in a folded pile, 31.

In the drawings I have shown the folding mechanism as consisting of a pendent swinging frame, 34, carrying at its lower'end guiderollers 35 for the fabric, and being connected at its upper end by a rod or rods, 36, to acrank or cranks, 37, on the driving-shaft 38, which imparts a vibrating motion to the frame to fold the cloth back and forth in layers.

I claim as my invention The rotating spring-beetler consisting of a shaft carrying elastic metal bands bent into coiled or similar form, and disks or plates carrying stops for the outer ends of the bent bands, substantially as set forth.

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