Abstract: 18,386. Page, S. E., [Cumnock, A. J.]. Aug. 16. Cutting-out -A machine for treating woven or knitted tubular webs, comprises means for supporting and stretching the same, and for moving the web over the supporting-frame. During passage over the supporting-means, the web may be inspected, sheared, singed, or otherwise treated. In the modification shown in Figs. 1 ... 10, means are employed for cutting shirt bodies, sleeves, &c. from a tubular web. The bed 11, Figs. 1 and 3, carries uprights 12, on which are mounted standards 13, 14, the standard 14 being adapted to slide in keyways, at its upper and lower ends, by means of a screw 141. The standards consist of two uprights 15,16, Fig. 6, having inwardly-projecting ribs 17, and being spaced apart by a block 18. Between the upright:' of the standards 13, 14 are mounted sprocket-wheels 2 and sprocket-idlers 23, over which run sprocket-chains 24, the links of which are recessed at 28 and carry teeth 210, as shown in Figs. 8 and 9. The sprocket-wheel 2 on the left-hand side of the machine is driven by gearing from the shaft 22, the wheel on the right being connected to rotate simultaneously therewith by a cross-shaft 211, a collar 212 on the shaft 'carrying a bevel-pinion 213, which engages with a similar pinion 214 on the shaft 21. The collar 212 rotates freely in a bracket 215 on the adjustable upright 14. Mounted in bearings in cross-bars 110 extending between the frame uprights 12 are four trunnions 3, 31, carrying discs 32 .which support the drums 35. Gear-wheels 33 on the trunnions engage with worms 34 connected by speed gears with the main shaft 22. To the drums 35 are bolted flanges 36, Fig. 2, having hinged aprons 37, 38, the free ends of the aprons being lifted from the drum surface by springs 39. On the apron 37 is a shear blade 4 with forked ends 41, as shown in Fig. 4. On the apron 38 two curved shear bars 5, Fig. 5. are carried. Just above the bed 11 and below the sprocket-wheels 2 are mounted two longitudinallyextensible or telescopic shafts, which consist of parts 6, 61 splined together. The free ends of these shafts carry gear-wheels 62 connected by speed gearing to the main shaft 22. The shafts carry four rolls 63, which may have rubber facings 64. One of the shafts 6, 61 carries stationary collars 65, Fig. 7, outside of the roll 63, each of which supports a shear blade 66. The other shaft carries a pair of rolls 67 mounted to rotate with it, each having a spring-supported apron 68 pivoted to it. The rolls 65, 67 are located in recesses formed to receive them at the bases of the uprights 13, 14. A frame 7, formed of parts 71, 72, is loosely and detachably mounted between the uprights, the parts 71 having curved parts 74 each fitting an arc of the sprocketwheel 2. Shear blades 75 are bolted across on either face of the frame 7, the edge of the blades being flush with the parts 71. In operation, the frame 7, Figs. 1 and 3, is introduced into one end of a tubular web 8, and the frame slid into position in the machine, the right-hand upright being moved out for this purpose by the screw 141. The upright being returned to position and the machine started, the web is fed over the frame by the engagement in it of the chain-teeth 210. The rotation of the drums 35 brings the shear blades 4, 5 alternately over the blades 75 on the frame, and cuts the web into shirt bodies, as shown in Fig. 10. The angularity of the shear blades 4, 5, 75 is so related to the feed-speed of the web that the blades cut straight across the material. The edges of the web passing over the outer faces of the bars 71 are severed by the shear blades 66 acting against the blades 69 on the apron 68, Fig. 7, the web being flattened and further fed downward by the rolls 63. By varying the speed-gear train between the worms 34 and the driving-shaft, the drum may be rotated at any desired speed, and the shirts cut with longer or shorter bodies. Also, by adjusting the movable upright 14, the side play between the frame and the sprocket-chains may be arranged to suit any thickness of material. By employing aprons of different breadths, shirts of varying chest measurement may be produced. In further modifications, the frame, uprights, sprocket-wheels and chains and driving-means, drums and supporting trunnions, and driving-connexions are as above described. An arrangement for throwing the drums out of action;when desired is shown, and consists in mounting`the main driving-pinion loosely upon its shaft, and, when desired, causing it to rotate therewith by means of a clutch collar operated by a handle. Arrangements are described in which a pair of horizontal shafts situated between the sprocket-wheels 2 and the bed-plate carry rotating shear blades, which effect the cutting of shirt sleeves from the web. Modified methods of mounting the web-supporting frame, and of feeding the fabric downwards by rolls supported above the frame, are described.
