Definitions

  • This invention relates to apparatus for the shrinking or stretching of flexible sheet material, particularly but not exclusively woven, knitted or other textile fabrics, and has for its object to provide such apparatus of simple form to which suitable flexible sheet material, in the piece or as made up into garments, readily can be applied for treatment.
  • an apparatus for the shrinking or stretching of suitable flexible sheet material, comprises a plurality of narrow materialengaging members-hereafter termed engaging mem-- bers-the upper surfaces of which, taken together, occupy the same general plane, each of which upper surfaces has a roughened or serrated formation to engage with the under surface of the material when it is laid and pressed thereon, which engaging members are supported on the surface of a lower fixed member and so interconnected and mounted by lost motion connecting means that (a) they can all be held assembled but slightly separated by narrow gaps between adjacent engaging members, or (b) they can all be moved from the separated position and brought into contact, to eliminate the gaps.
  • the area of the supporting surface over which the engaging members extend when separated by the gaps is greater than the area over which the engaging members extend when they are brought into contact, by an amount equal to the total area of all of the gaps.
  • the upper movable pressing members for pressing the material onto the roughened surfaces of the engaging members and for holding it pressed thereon can be as desired and be weight or spring operated, and the surface thereof in contact with the sheet material (or a dampening cloth or the like laid over the sheet material) must be polished or glazed, to .allow the material to move thereunder by the pull of the engaging members with but little friction, when the said material is actually being shrunk or stretched.
  • the pressing member can be an electrically heated iron, suitably supported and brought into and out of action, said iron preferably being under thermostat control.
  • the installation can also, if desired, include means combined with the iron or otherwise for supplying steam or moisture to the material being treated or to a covering dampening cloth or the like therefor.
  • the roughened or serrated formation of the upper surfaces of the engaging members can be effected in a great variety of manners. For instance, they can have alternating V-section ridges and channels, for example 3,044,143 Patented July 17, 1962 2. approximately 0.020" (0.5 mm.) deep, and 0.033" (0.8 mm.) from crest to crest.
  • Apparatus in accordance with the invention can be of such dimensions that it is possible to treat woven cloth or the like for the full width thereof so that successive portions of a roll of cloth can be treated.
  • the apparatus can be designed for use in the shaping of various parts of garments during the initial makeup thereof, and is especially useful for shaping such parts of garments located in the areas around the shoulders, bust, waist, hips and seat portions of the garment.
  • apparatus according to the invention is particularly suitable for restoring to the original condition portions of garments which in wear have been stretched or otherwise deformed.
  • FIG. 1 is a front elevation of one form of apparatus according to the invention which is particularly suitable for the treatment of trousers which, in wear, have developed baggy knees.
  • FIG. ,2 is a side elevation of FIG. 1.
  • FIG. 3 is a plan of FIG. 1 with parts broken away.
  • FIG. 4 is a plan to a larger scale of the materialsupporting portion of the structure.
  • FIG. 5 is a section on the line VV, FIG. 4.
  • FIG. 6 is a fragmentary front elevation partly in section of a portion of FIG. 1, and
  • FIGS. 7 and 8 are portions of the apparatus in two different positions, shown in section to a greatly enlarged scale, to illustrate the lost motion action.
  • the apparatus shown in the drawings comprises a flat rectangular supporting plate 9 adapted to be screwed to a table top or the like.
  • the plate 9 is provided adjacent one end with a pair of spaced-apart upwardly projecting brackets 10 having upper and lower flanges the upper flanges of which are fixed to the underside of one end of an elongated built-up plate structure 11 by suitable fastener elements, to support the plate structure 11 parallel to the supporting plate.
  • This plate structure 11 has a central longitudinally extending recess 12 in its upper surface, rounded ends and longitudinally extending parallel sides.
  • the parallel sides have detachable retaining strips 13 with slight inwardly projecting flanges 14 extending throughout their lengths, and outer semicircularshaped detachable retaining members '15 with inwardly projecting curved flanges 16 for attachment to the semicircular ends of the supporting plate.
  • Its upper surface is serrated with alternate V-section ridges and channels (not shown in the drawing owing to the smallness of the scale) such as hereinbefore set forth, whichextend longitudinally of the bar. This serrated surface, however, projects to a desired extent above the level of the upper surfaces of the flanges 14 of the retaining strips 13 at the edges of the supporting plate 11.
  • the upper surface of the supporting plate 11 at one semi-circular end also has slidably mounted thereon a segment-shaped plate 18 the straight edge 19 of which is directed to and parallel with the fixed engaging member 17.

  • another similar segment shaped plate 20 the straight edge 21 of which is directed to and parallel with the fixed engaging member 17.
  • the ends 27 of these movable engaging members are reduced in height to slide beneath the flanges 14 and so that their serrated upper ridged surfaces28 project well above the level of the upper surfaces of these flanges.
  • each movable engaging member 26 is interconnected by lost motion connecting means as shown in FIGS. 7 v and 8 wherein each movable engaging member 26 is bored at 29 from one vertical face to the other, to take a horizontal pin 33 as a sliding clearance fit.
  • This bore 29 is enlarged at one end 31 to accommodate a head 32 on the pin as a sliding fit providing a lost motion connecting means.
  • the pin 30 is a tight force fit into an aligned bore 33 in the next adjacent movable engaging member 26.
  • two such pins 30 connecteach pair of adjacent engaging members 26, one pin near one end and the other pin not I so near the other end but somewhat displaced to allow for the symmetrical connection of all the engaging memhere.
  • the arrangement is such that the fixed engaging member 17 does not have any'cnlarged bores 31 for the heads 32 of the pins, but only bores 33 into which the pins are a force fit, so that the heads 32 of these sides thereof.
  • the outermost movable members 34 on each side come wholly below the flanges 16 and do not have an upper serrated surface.
  • These special movable members 34 accommodate only the sliding heads 32 and pins 30, and are fixedly secured by screws 35 to the slidable segmental plates 18 and 20.
  • the head 32 only allows the separation of the adjacent engaging members 26 up to the extent of the gap, that is, 0.020", and when the said adjacent members are in contact to eliminate the gap, as shown in FIG. 8, then the head 32 is still fully accommodated in the enlarged end of the bore 31 in which it is housed, i
  • segmental plates 18 and 20 are in their outermost extreme positions (FIG. 4), if they are moved one towards the other in a uniform manner then the gaps, simultaneously from each end of the supporting plate, will be closed successively until they are all closed, and vice versa.
  • crank pin 39 has connected thereto one end of a short link 49, the other end of which link is pivoted to the pin 22- projecting below the nearest and adjacent segmental plate 18.
  • the other crank pin 41 is connected by a long link for the apparatus.
  • the arrangement is such that when the vertical spindle 37 is turned in one direction through a defined angle, the movable engaging members 26 are separated, and when turned in the other direction these engaging members are closed together. From the position shown in FIG. 4, where the gaps are open, upon turning the spindle 37 in a counter-clockwise direction the segmental plates 18 and 2t) and all the movable engaging members 26 will be moved towards the fixed engaging member '17, and all the gaps will be closed.
  • the base plate 9 has a lower bearing for the vertical spindle 37 which towards the lower end has a crank disc 43 (FIG. 3) the crank pin of which is connected by a link 44 to a two-armed lever pivoted at 45 in the base plate 9, the outer arm 46 of which constitutes the operating handle
  • the mechanism By moving this handle 46 in a clockwise direction (FIG. 3) through a desired angle, the mechanism effects the separation of the engaging members, and by then moving it in the other direction, the closing-together of such engaging members.
  • the closedtogether position is shown in FIG. 3.
  • the base plate 9 has fixed thereto two similar spacedapart upwardly projecting brackets 47 the upper ends of which have bearings for a horizontal spindle 48 which has fixed thereto two connected shaped levers 49 the outer ends of which support a carrying spindle 50 for apertured carriers 51 to which the upper part of the casing of a rectangular-shaped electric iron 52 is adjustably connected by studs and nuts.
  • the lower polished or glazed pressing surface 53 of this iron when in the lowered position (shown dotted in FIG. 2) is located in the plane of the ridged surfaces 28 of the engaging members 17 and 26.
  • connection of the carriers 51 to the spindle 50 is such that the iron can have a slight angular motion about the said spindle so that it always lies flat on the ridged surfaces 28.
  • the spindle 48 has a lever 54 fixed at each end, the other end of which lever is connected by a tension spring 55 to a pin 56 on the adjacent supporting bracket 47.
  • the springs 55 in the out-of-action full-line position (FIG. 2) of the iron are located on one side of a dead centre of the levers to hold the iron in the raised position. In this position, shaped portions of the levers 49 are kept pulled onto an abutting stop 57 which connects the brackets 47 towards their upper ends.
  • the iron 52 has an operating handle 58 by which it tis-turned to bring the springs 55 to and past the dead centre by a desired angle to the operating position of the iron (dotted line 'FIG. 2) where it is held pressed on to the ridged engaging members.
  • 59 is the material to be shrunk which is located between the ridged upper surfaces of the movable engaging members 26 (the fixed engaging member .17 is similarly ridged) and the polished surface 53 of the iron 52.
  • the longitudinal dimension between the extremities of the members shown in this figure is D.
  • the engaging members 26 are set into and held in the separated position (FIG. 4). Then the waist end of the trousers leg is drawn over the free end of the supporting plate 11 with its engaging members, and the said leg portion brought into such a position that the normal crease down the front of the knee is located centrally and in the longitudinal direction of the supporting plate. Then this portion of the fabric is pressed down by hand on to the'ridged upper surfaces 28 of the engaging members. A dampened cloth is then laid over this portion of the fabric of the trousers leg and then the iron 52 is loweredfto exert pressure thereon.
  • Stretching may be as readily effected by first setting the engaging members 26 into the closed position (FIG. 3) and this treatment may be used for restoring the crumpling-up or wrinkling at the rear portion of the knee of a trousers leg. Similarly, this stretching treatment could be given to the upwardly crumpled or shrunken lower portions of trousers legs, or even to the pulled or workedup ends of coat sleeves or the like.
