MACHINE FOR TREATING PLIABLE TUBES.

Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed April 19, 1905. Serial No. 256,384-

T0 all whom it may concern.-

Be it known that I, ARTHUR JAMES CUM- NOOK, a citizen of the United States, and a resident of Rye, New York, have invented certain new and useful Improvements in Machines for Treating Pliable Tubes, of which the following is a specification.

My invention relates to a machine for treating fabrics, which may be in the form of tubular webs either woven or knitted.

In a broad aspect it comprises means adapted to be placed within the tubular web for supporting and, if desired, for stretching the same, together with means for moving the web over such supporting means.

It may also include any desired means for treating the web during its passage over the supporting means-that is, the supporting means may be used merely for stretching and shaping the web, or the web may during its passage be inspected, sheared, singed, or otherwise treated.

A further development of my invention.

comprises the separating and supporting of the web as above described and while or after it is so separated and supported cutting or piercing it, and particularly cutting it into pieces of desired form for any particular purose.

P For the purpose of illustrating the invention I have shown and will describe a machine for shearing and trimming Webs to produce therefrom garment-bodies or other articles. The tubular web may be woven as shown in my pending application, Serial No. 205,695, filed. April. 30, 1904, or in any other desired manner. I have shown my machine as arranged to cut from a tubular Web shirtbodies, though it may obviously be so modified as to cut articles of other shapes and for other purposes, as desired.

In the drawings, Figures 1 and 2 are respectively front and side elevations of my device. Fig. 3 is a vertical section through the line 3 3 of Fig. 2. Figs. 4 and 5 are elevations of aprons detached from the rolls on which they are carried. Fig. 6 is a transverse section on the plane 6 f Fig. 3. Fig. 7 is a vertical section through the plane 7 7 of Fig. 3. Fig. 8 is an elevation of a portion of a sprocketchain detached Fig. 9 is an end view of the rollsshown at the lower portion of Fig. 3 detached from the frame. Fig. 10, on a reduced scale, shows the pieces cut from the web.

1 designates a supporting-frame having a bed-plate or bed 11' and uprights 12 onwhich are mounted standards 13 and 14, the standard 13 being stationary and the standard 14 being adapted to slide toward and from the standard 13 in keyways at its up er and lower ends by means of a screw 141. ee Figs. 1 and 3.) The standard 13 consists, as shown in Fig. 6, of two upright bars 15 and 1 6, having inwardly-projecting ribs 17 and spaced apart by a block 18, leaving a recess 19. Be tween the uprights 15 and 16 are mounted sprocket-Wheels 2', the shafts -21 of which are connected by suitable speed-gears (see Fig. 2) to a main drivingshaft 22.. Sprocketidlers 23 are also mounted between the uprights 15 and 16, and over these and the s rocket-wheels 2 run sprocket-chains 24, t e links 25 of which have lateral projections 26, formed with lateral recesses 27 and a front recess 28, from the inclined faces 29 of which project teeth 210. (See Figs. 8 and 9.) It will be noted that it is the sprocket-wheel2 at the left of the drawings,.Figs. 1 and 3, that is positively connected with the main drivingshaft 22 and that the opposite sprocketwheel (shown at the right ofthose figures) is connected to rotate simultaneously there with by means of a cross-shaft 211'. On this cross-shaft is splined a collar 212', (shown in dotted lines, Fig. 1,) carrying a bevel-pinion 213, engaging with a similar pinion 214' on the shaft 21. The collar 212 rotates freely in a bracket 215 on the upright 14, so as to move therewith.

Mounted in suitable bearings in cross-bars 110, extending between the frame-uprights 12, are

trunnions

3 and 31, four in all, to each of which is secured a drum-supporting disk 32. On the trunnions 3 are gear-Wheels 33, meshing with oppositely-pitched Worms 34, which are connected by suitable trains of speed-gears (see Figs. 1 and 2) with the main shaft 22. Between each pair of disks 32 is detachably supported a drum 35. To each drum 35 in the construction shown are bolted two flanges 36, to which are hinged aprons 37 other drum 38 (see Fig. 5) two diagonallyplaced bilaterally symmetrical shear-bars 5 are shown, each comprising an approximately symmetrical semicircular central portion 51, straight portions 52, and arc-shaped portions 53. From the center of the portions 51 eX- tends a shear-bar 54, located at approximately a right angle with an imaginary diagonal line on the apron relatively to which the shear-bars are mounted.

Just above the bed 11 of the machine and below the sprocket-wheel 2 are mounted two parallel longitudinally-extensible shafts, each consisting of parts 6 and 61, splined together. At the free end of each shaft portion 6 and 61 is a gear-wheel 62, connected by a suitable train (clearly shown in Fig. 2) to the main shaft 22. On each of the shaft portions 6 and 61. are secured rolls 63, four in all, which may have rubber facings 64. On one of the shafts 6 61 outside of the roll 63 are mounted stationary collars 65, oneof which is shown in Fig. 7 and each of which supports a shearblade 66. On the other shaft 6 61 is a pair of rolls 67, mounted to rotate with the shaft and each having an apron 68 pivotally secured to and spring-supported from the roll,

as are the

aprons

37 and 38, before described.

(See Fig. 7.) As is clearlyshown in Figs. 1

' the projections 26 of the sprocket-chains fit around the sides of the bars 71, which are shaped to enter the recess 28-for a substantial part of their length. (See Figs. 3 and 6.) On each side of the frame 7 and extending from side to side thereof are bolted angularly-disposed shear blades'or bars 75, the edges of which are at least flush with the edges of the bars 71. (See Fig. 6.)

The operation of the machine is as follows: The frame 7 is introduced into one end of'a continuously-woven tubular web 8 and the frame slid down into the position shown in the drawings, Figs. 1 and 3, the upright 17 being first moved outward to the right of Figs. 1 and 3 for this purpose. When the upright 17 is again moved inward, so as to hold the frame 7 loosely in place, and the power applied to the machine, the web will be fed downward ovcr the frame 7 by the engagement of the teeth 210 of the links 26 in the web. The rotation of the drums 35, one of which is located on each side of the frame 7,'will bring the shear-blades 4 and 5 alternately over the shear-blades 75 on the frame and cut the web into shirt-bodies, as shown in Fig. 10. It will be seen that the bars 4 will cut the lower end of the shirt on'both sides of the web, the curved furcated ends 41 acting to remove a quadrantal gore from each side of the shirt, thereby producing skirts at the front and rear of the shirt. The next semirotation of the drums 35 brings the blades '5 against the blades 75 on the front and rear faces of the webi. a, on both sides of the frame 7. The semi-annular or areshaped'portions 51 act to hollow out the neck of the two shirts, the parts 52 slope the shoulders, and the parts 53 cut the armscyes. In addition, the aprons 38 on one side of the frame 7 may have blades 54 to cut vertical slits at the back of the shirt. (See Fig. 5.) By cutting the shirts neck to neck and skirt to skirt, as shown in Fig. 1.0, a minimum waste of material is made. It is of course understood that the angularity of the shearblades 4, 5, and 75 is so related to the feed speed of the web as to cut the shirt square of the material-e. g., the blades 4 cut straight across the web.

The operation thus far described is, however, incomplete, as the edges of the web which pass over the outer faces of the bars 71 have not been severed. These edges are cut by the shear-blades 66 acting against the blades 69 on apron 68, the web being flattened and further fed downward by the pairs of rolls 63. The completely-severed bodies then drop through the bee l 1 in a suitable re ceptacle; (Not shown.)

It is obvious that to cut the shirts with longer or shorter bodies it is only necessary to alter the speed-gear train between the worms 34 and the driving-shaft 22 so as to rotate the drums 35 at the desired speed. It is also clear that by delicately adjusting the upright 17 the side play of the frame 7 between the faces 29 of the links 24 may be adjusted to allow for different thicknesses of fabric. In the same way the machine is adjustable to cut shirt-bodies ofdiflerent chest measurements from webs of different diameters by substituting frames 7 and

aprons

37 and 38 of suitable Widths, the shafts 6 61 being made telescopic or longitudinally self adjusting and. the collar 212 being made to slide on the shaft 211 for this purpose. 3

Reference to the dotted lines, Fig. 10, will show thatthe shear-blades in the other apron 38 (not shown in Fig. 5) are somewhat differently disposed-t. 6., to cut the front of the shirts including the neck-opening, shoulderslope, and arm-scycs. It will be seen that the neck-opening cut bythe portions 51 is of greater depth than that shown in Fig. 5 and that the slot cut by the blade 54 is omitted.

While I have described the construction and arrangement of the machine as adapted to cut a particular garment, it will be plain that changes easily within the skill of the mechanic can be made to adapt the machine to IIO out other garments or articles of any sort,

straight or curved form and whether the articles are all of the same pattern, or of alternately different patterns, or on one or both sides. By the term curved as applied to the shear-blades I of course include any deviation from a straight line. So by the term frame, as used to describe the part 7, I intend to include any suitable device or means for entering the web and separating and supporting it. I wish it further understood that many mechanical changes in the form and arrangement of parts and generally in the construction of the machine may be made without departing from my invention.

Where it is desired to use the particular machine illustrated for treating the web in other ways than by cutting it into desired articles, it would of course be possible to remove the

rolls

35 and 67, as already described. This would of course eliminate the cutting operations. By proportioning the width of the frame 7 to the diameter of the tubular web the latter may be stretched to any desired extent. By disconnecting the pinions in the speed-gear train between the worms 34 and the main shaft 22 the positive action of the teeth 210 on the web would be eliminated and the web drawn over the frame only by means of the rollers 63, or, conversely, by disconnecting the shaft by which therollers 63 are driven from the main shaft the chains 24 could be used as the sole means of drawing the tubular fabric over the frame 7 or other supporting means.
