Abstract: 10,005. McNaught, W. May 2. Washing.-Relates to improvements in machinery for washing and scouring wool and other fibrous materials. Fig. 1 shows a pair of squeezing-r oilers a, b, the upper one a being acted upon by the weights d by means of the rods c, p and the levers m, q. The weights d rest on springs 57 carried by the saucer 56 ; a light spring 58 is provided above the weights. Or the rod c may, as shown in Fig. 1<a>, be provided with a collar f resting on a spring g in the cup h, which has a central hole j to receive the end of the rod, and is attached to the lever m by two links k. Fig. 2 shows an immersing-apparatus in which a rod 3 is pivoted at one end to a rocking lever 6 attached by a pivot 7 to the fixed frame of the apparatus, and is pivotally connected at the other end to the rake a, either, as shown, by fastening it to the sleeve 8 which connects the rake with the crank x, or by other convenient means, say by connecting the rod 3 to the crank-pin of the crank x ; the rocking lever may be slotted at either end for adjustable connection to the frame or to the rod 3, or the fulcrum point 7 may be adjustable on the frame. An immerser 11 is suitably connected to the rod 3 and is thereby given an almost elliptical motion, which can be raised by making the adjustments described above. Another method of connecting the immerser with the rake is shown in Fig. 3, in which the immerser is provided with a bracket 14 connected to the rake by two links 15 pivoted to the crank-pin of the crank x or at some other point on the rake. The horizontal part 17 of the bracket 14 rests on a cam 18 of suitable form. Fig. 4 shows a combination of immersors 22 with rakes t ; the immersers are rigidly connected to a bar 21, which is attached to one rake by an adjustable pivot 20 and rests on a roller 54 carried by the other rake or by the sleeve 8 ; an upper roller 55 may also be provided. In another arrangement, the bar carrying the immerser has both ends free and resting on cams. Instead of separate immersers, bars or tubes carrying sets of prongs are used. Another form of immerser consists of a rectangular box open at the bottom and perforated at the top ; the perforations are covered by a valve which closes when the immerser is rising and opens when the immerser is falling, thereby agitating the liquid. Straight or curved prongs may be provided either at the centre or along one side. Fig. 10 shows a frame for delivering the wool to the incline leading to the squeezing-rollers. The frame 35 carries prongs 36, generally of unequal length, and is hung by rods 37 to a bar 38. One end of this bar rests on a roller 39 pivoted on the bracket 40 which is fixed to the frame ; the other end rests on a cam 41 mounted on a shaft 42. This shaft carries an elliptical gearwheel 43, driven by another elliptical gear-wheel 44 ; attached to the wheel 43 on the cam 41 is a pin 45 which drives the rod 46 connected to the frame 35. The gear-wheels may be of any suitable shape to give a variable velocity ratio, or the shaft 42 may be moved by ordinary gear-wheels or other mechanism, and the pin 45 may be at the end of a crank keyed on the shaft 42. Fig. 11 shows a propelling-frame 61 with prongs 62 fixed rigidly at its ends, and intermediate prongs 63 pivoted to brackets 64 at points 65 and connected at their upper ends by a coupling-rod 66 : a radius rod 67 pivotally anchored at one end is 'connected at the other end to the upper end of one of the prongs 63 or to the rod 66. The prongs 63 thus have a greater horizontal movement than the end prongs 62.
