Abstract: 12,342. Lumb, T., Walshaw, T., and White, D. May 30., Washing.-A machine, in which the two operations of milling or fulling and washing or scouring textile piece goods can be performed in succession, is constructed with a framing a, Figs. 1 and 2, a draught-board b, and squeezing - rollers c, c<1>. The upper roller c' is supported in bearings in levers d pivoted on a shaft d<1> carried in brackets d<11> or in the side frames. The free ends of the levers d are coupled by links d<111> to side levers d<1111> fast on a shaft e and each. provided with an adjustable rod f carrying adjustable weights f<1>. The roller c' is driven from the main shaft c<11> by spur gearing u, u<1>, u<11>, u<111>, the pinion u<11> being mounted upon a stud carried by the bracket d<11> and mounted on or close to the pivot of the lever d, so as always to gear with both u<1> and u<111>. Between the draught-board and the rollers are loosely mounted, upon two inclined spindles, a pair of guide-rollers g, having corrugated or fluted surfaces, or cut or formed with V- grooves or the like, and intended to break up the longitudinal creases or "rigs" " in the cloth. The spindles are secured in elongated slots to transverse rods, so as to be adjustable therein by right and left hand screws. The fabric passes from the draught-board between the rollers g, and then between the nipping-rollers c, c<1>. The knock-off mechanism, for stopping the machine when a knot or enlargement on the travelling fabric prevents it from passing freely, consists of a lever h, Fig. 2, mounted on the pivot centre b<1> of the draughtboard and provided with an enlarged end having a cam-groove h<1> in which works a bowl i<1> carried on the lower end of a lover i pivoted at i<11> and having an upper forked end engaging in an annular groove in the boss of the sliding member k, Figs. 2 and 5, of a clutch device mounted upon the driving-shaft c<11>. The sliding member has pins k' extending into corresponding openings in a disc k<11> fast on the shaft c<11>, and projecting therethrough into the path of lugs l connected to the loose driving-pulley l<11> of the main shaft, whereby the pulley drives the shaft as shown in Fig. 5. The lugs are carried on a metal strap l<1>, which is adapted to give a little when the lugs are first struck, and thus avoid excessive shock. When the draught-board is moved into an abnormal position by means of any obstruction, the lever h moves in unison therewith, its cam end descending and causing the lever i to move the sliding member and its pins away from the pulley l<11>, thereby breaking the connection of the latter with the machine. The cam-groove h<1> has a straight extension h<11> at its end. A link j, Fig. 2, hung on a pin, holds the knocking-off lever in its inoperative position. After leaving the rollers c, c<1>, the fabric passes to the trough m, at one end of whish are two rams n which are caused alternately to slide transversely backwards and forwards by any mechanical motion, such as rods connecting them to links n<11> connected to studs o' on a horizontal disc o mounted on a vertical shaft o<11> which receives a rocking motion by levers p, p<1> from a faceplate q driven by spur gearing from the main shaft. The rams alternately strike the fabric, to obliterate any creases produced by the rollers c, c<1>. To assist this action, vertical libs or protuberances, corresponding to the curved faces of the rams, are formed on the opposing side of the trough, which side, or a portion of it, is hinged to the front of the trough and held in position by a spring, by which means it may move slightly to prevent the cloth from jamming. The rear end t of the bottom of the trough is hinged on a transverse shaft t<1>, which can be turned by a hand-lever t<11> placed outside the machine, so that, when using the machine for washing and scouring purposes, the hinged bottom is lowered out of the way, and the rams n are thrown out of action. The stopmotion, the method of mounting the upper roller c<1> and the guide-rollers g, and the improvements connected with the trough may be applied to existing machines.
