Definitions
- This invention relates to methods of and apparatus for restoring to original condition a knitted fabric one loop of which has become enlarged or has been pulled. accidentally in the handling of the fabric after the knitting operation has been completed.
- a relatively light or fine strand of thread or yarn is employed, for instance a strand of nylon, silk or rayon, or of mixtures of these, with or without other materials.
- the strands or threads of yarn so employed have great tensile strength and may not be easily broken but, after having been incorporated in a knitted fabric such as a stocking, the pulling of a thread may very easily occur for any one of a number of reasons, even while being handled in the most careful manner by a skilled operator.
- a loop of the knitted fabric may be greatly enlarged without being broken, the material added to one loop by the pulling being withdrawn from the adjacent loops on both sides of the pulled loop, these adjacent loops being thereby reduced.
- two additional series of normal loops disposed parallel t and upon opposite sides of the elongated series of reduced loops, are drawn laterally into closer relationship.
- the present invention relates to an improved method and to an improved apparatus for thus restoring to original condition an area of a knitted fabric which has been rendered unsightly and defective by the pulling of a loop and whereby the operation of restoration may be accomplished more accurately and more rapidly than heretofore, a very substantial proportion of the cost of restoring knitted fabrics being eliminated.
- each reach of each of the reduced loops disposed upon one side of the pulled loop a number of times while the fabric is under tension, and repeating the operation as many times as may be necessary, material is withdrawn from the pulled loop and is added to all of the reduced loops located on that side, to the end that, in a relatively short time, all of such reduced loops have been restored to their original sizes and the size of the pulled loop greatly reduced.
- the operation is then repeated upon the opposite side of the pulled loop, the remaining excess material of the pulled loop being caused to creep or move into the reduced loops on that side, each of the deflecting blows having been directed away from the pulled loop.
- this instrument comprising a circular series of work engaging or impact elements and means mounting said members in such manner that they may be revolved bodily about an axis, the outer ends of the elements being disposed in a common plane and in a circle.
- Power means is provided for rotating the mounting so as to move the elements which it carries at a desired speed.
- the outer end surfaces of the "impact elements are sloped rearwardly, having in mind the direction in which they are moved, so that no such element may catch or snag a thread and thus further injure. rather than restore, the fabric being acted upon.
- the details of construction of the implement comprising the impact or work engaging elements and the rotatable support or mounting therefor may be varied substantially without departure from the invention but I prefer a design in which the impact elements are of metal and comprise relatively thin and somewhat springy or resilient arms which extend outwardly from the mounting and the smooth work engaging ends of which are located in a circle concentric with the axis of the mounting and in a common plane.
- an experienced operator may bring the rapidly moving work engaging surfaces of the impact elements very accurately into contact with the fabric at a selected point and, by advancing it while maintaining the circle of work engaging ends of the work engaging members in a plane, can accurately cause the instrument to deliver light repeated deflecting blows to successive threads disposed in a straight line along the fabric.
- a displaced looped thread may be struck repeated light blows at a number of points disposed in a straight lin by drawing the instrument across the surface of the knitted fabric, and a single thread thus acted upon and caused to creep, as it were, through the fabric, withdrawing a desired length of material from the pulled loop and adding it in accurate proportions to several reduced loops.
- the work engaging members of the apparatus may be fabricated of any suitable material, steel being preferred, but these elements may be formed of plastic material, animal bristles, fiber, or, in fact, any material which can be fashioned into elongated, relatively thin, smooth and pref-

- Figure l is a perspective view of the implement as it will appear when held in one hand of the operator while being used, the operators other hand encircling a mending cup over which the fabric t be repaired has been stretched;
- Figure 2 is an axial section through the implement
- Figure 3 shows, on a relatively large scale, a small area of a knitted fabric, such for instance as a portion of a sheer stocking, a pulled loop being shown, likewise a number of reduced loops, these loops being shaded, the fabric shown being thus defective and needing restoration with the aid of the implement shown in Figures 1 and 2;
- Figure 4 is a section on line 44 of Figure 3;
- Figure 5 is a View similar to Figure 3, showing the same area of fabric, the fabric, however, having been placed under tension on the menders cup, or in some other manner, the defective portion having been modified somewhat because of the applied tension;
- Figure 6 shows the same area of fabric after the restoration operation has been partially completed
- Figure '7 shows this fabric after the restoration operation has been fully completed.
- FIG. 7 An enlarged plan view of a small section of knitted fabric is shown in Figure 7.
- This fabric is in its original, as knitted, condition, having been restored to perfect condition after having been damaged by the pulling of a thread, by the applicants method and with the aid of his implement.
- the yarn employed in the original fabrication of the fabric may be of any suitable composition and the denier and gauge may vary widely, the improved method and instrument being applicable to all weights and grades of knitted fabrics. It may be said that the fabric shown in Figure 7 comprises three course or rows of loops, an upper row the individual loops of which are indicated at a, a through a an intermediate series of loops indicated by b, b" through if and a lower series of loops indicated by c, 0, through c.
- This instrument comprises essentially a core or mounting it! having extending outwardly therefrom a plurality of work engaging elements H, the core being mounted upon the end of a shaft or spindle l2 and the outermost or work engaging tips of the elements H being disposed along the arc of a,,circle centered on the axis of the spindle E2.
- the material of which the mounting it is fabricated may be varied widely, likewise the material of which the elements I! are formed, the manner of attachment of these elements H to the hub l8, and even the overall shapes of the elements ll can be varied within gamma? llimits.. -In every instance, however, the outer .inclined rearwardly, having in mind the direction of rotation of the implement when it is in use.
- the implement .is to berotatedzin the direction of the arrow w and each of the elements H is curved rearwardly for reasons which will become more apparent when its use is more particularly described.
- the operation has the general aspect of a brushing operation, the forwardly facing surfaces of the elements I striking and sliding over each contacted section of thread, thus tending to enlarge the reduced loops and restore them to -nor-. mal size, increase in size of the several reduced loops being at the expense of the enlarged loop 17*, which gradually loses size.
- the operator will either turn the mending cup 180 to reverse the fabric, or will reverse the implement, it being easier and simpler to reverse the fabric.
- the implement may be used exactly as previously described to enlarge the remaining aligned loops which have previously been reduced, being moved, oneach working stroke, away :from the .hole :h and (generally) toward the operator, When such :enlargement has been .fully effected the pulled loop :2) will have been reduced to :normal size so that :the
- the instrument is revolved by mechanical power taken from a geared down electric motor, the motion of the rotor of the motor being communicated to the spindle L2 by means of a flexible shaft enclosed within the flexible tube indicated at T in the drawings, the :source'of :power being indicated at
- the motor and its gearing are preferably so designed that the "implement is revalved 'at an angular speed of approximately -'400 revolutions per minute, but higher .or lo'wer'spe'ed's of rotation are permissible.
- each of the elements ll of the implement is self sustaining in character in' that it supports itself and'generall-y maintains its 'shape'when at rest or in motion.
- the circular path along which the work engaging faces of the implement move when theimp'lement is m use "is therefore a definite one, permitting the "accurate positioning of the implement relatively to the work.
- the width of the work engaging "face of each element should be no greater than the width of a normal course of the fabric upon which the implement is being used in a normal manner, otherwise the undamaged loops of courses of "the fabric adjacent the damaged course being corrected may be disturbed and "the desired result not realized.
- the work engaging face of anelement ..-0'l-8 inch .in diameter naturally cannot exceed this dimension :in width and actually will be substantially .less when the fabric is under tension and the instrument pressed lightly against it.
- the loop diameter of the damaged course of the fabric being repaired is quite small it may be desirable to reduce the effective widths of the work engaging faces of the implement and 'to thus avoid the possible disturbance of the undistorted adjacentcourses of the knitted fabric.
- the diameters of the loops of knitted hosiery of conventional character vary between .0156 inch and .0312 inch, the most common loop diameters being .020 inch (15 denier) and .021 inch (30 denier), and for restoring pulled threads in knitted fabrics of this character the work engaging needle of "circular "cross section and having a d ameter *of .018 inch will perform in an em-i-' nently satisfactory manner.
- the width of the work engaging face of the element may be still further narrowed by reducing the diameter of the work engaging element.
- the elements H are curved uniformly, the radius of curvature being about one-half inch.
- the work engaging elements may be detachably secured to the hub of the implement, so that elements of difierent kinds may be employed with a common hub.
- the member ID may, for instance, be formed in two parts and the inner ends of elements ll clamped between these parts, thus making these elements readily interchangeable so that a damaged element may be quickly replaced or one set easily substituted for another when the implement is to be applied to diiferent types of fabrics.
- Apparatus for restoring to original condition a knitted fabric one loop of which has become enlarged and adjacent loops reduced comprising, in combinationpa spindle adapted to be rotated about its longitudinal axis, a hub fixed upon the spindle and rotatable therewith, and a circular series of self sustaining work engaging elements mounted upon said hub, said elements being adapted to successively engage the work when the hub is rotated, the work engaging surfaces of said elements at the outer ends thereof facing forwardly and outwardly and being smooth and no wider than a normal course of the fabric to be restored.
