Definitions

  • This invention relates to devices for use in the manufacture of ornamental fabrics, particularly pile fabrics, fringed fabrics and the like, to be used, for instance, as coverings, such as floor coverings, cushion covers, table covers and the like.
  • the forked member is constituted by a bifurcated bar having prongs of unequal widths, the line of stitches being thus formed close to the inner edge of the narrow prong, so that each loop comprises a long portion on one side of the line of stitches and a short portion on the other side.
  • rows of loops may be stitched to a base fabric in overlapping relation, the short portions of the loops of one row being overlapped by the tufts formed by cutting .the longer portions of the loops of an adjoining row.
  • the wider prong is provided with a cutting edge, preferably by being fitted with a removable knife-blade at or near one end.
  • aguard for shielding the fingers of the operator is provided for the cutting edge and is preferably removably fitted to the wider prong along with the knife-blade.
  • yarns of differentcolour and of different lengths may be wound successively on the bifurcated bar in accordance with directions or in accordance with a chart which may be marked on the base fabric.
  • the loops are evenly cut and an' the prongs when wrapped by the yarn, there is preferably provided a distance piece or spacer which is preferably pivoted to the wider prong and is engageable with the narrow prong.
  • Fig. 3 is a longitudinal section on the line 3-3, Fig. 1.
  • Fig. 4 is a longitudinal section on the line 3-3, Fig. 1.
  • Figs. 5 and 6 are, respectively, perspective views of the detachable knife and guard elements of the device shown in Fig. 1.
  • Fig. '7 is a plan view of the fork member from which the knife and guard elements have been removed.
  • Fig. 8 is a longitudinal section on the line 88, Fig. 7.
  • Fig. 9 is a plan view of the device shown in Fig.
  • Fig. 10 is a fragmentary plan view of the device shown in Fig. 9 modified to detachably receive the knife and guard elements of Figs. 5 and 6.
  • Fig. 11 is a plan view of the device shown in Fig. 7 with two extension bars attached thereto in series additive relation.
  • Fig. 12 is a fragmentary edge view of one of the extension bars and
  • Fig. 13 is a section on the line 13-13, Fig. 11.
  • the device illustrated in Figs. 1 to -6 inclusive comprises a thin fiat bar or strip of spring metal which is bifurcated to form prongs l and 2 separated by a longitudinal stitch-receiving gap 3; the prong 1 being considerably wider than the prong 2.
  • the wider-prong is formed at its free end with a hole 4 through which is looped a thin metal strip 5 constituting a distance piece the free ends of the legs of which are preferably brought together and riveted at 6.
  • the loop 5 is preferably flattened to the form shown in Figs.
  • the 4 and 8 andits legs are preferably shaped to provide an opening 7 which resiliently or frictionaiiy fits over and embraces the free end of the narrow prong 2 to hold it properly spaced from and parallel to the prong 1 when the usual winding of yarn or the like is applied thereto.
  • I Detachably fitted to the wider prong 1 are the knife and guard elements of Figs. 5 and 6, re- 11o to overlap the locking engagement spectively.
  • the guard element may be made of thin sheet metal having a shank 9 and U-shaped guard portion 10 joined at its lower edge by the neck 11 to one edge of the shank 9. Rising from the shank 9 are a headed stud 12 and two positioning pins 13.
  • the shank 9 is formed at one end with an upturned lip 14 affording a locking shoulder and at its opposite end with a folded back loop or hook 15.
  • the knife 16 is made of thin steel or safety razor blade stock and is formed with a razor edge 1'7, two positioning apertures .18 and a central clearance aperture 19. The two positioning apertures 18 fit upon the positioning pins 13 of the guard-shank 9. The clearance aperture 19 is large enough to admit the head of 'the stud 12.
  • the wider prong 1 of the forked member is formed near its free end with a key-hole slot 20 to receive the headed stud 12 and with two straight slots 21 to receive the positioning pins 13 which have rounded ends as shown in Fig. 3.
  • the prong 1 is further formed with a straight slot 22 to receivethe hook 15 which is adapted to overlie the prong 1 so as to normally prevent separation of the inner end of the guard-shank 9 from the prong 1.
  • the knife 16v is first laid upon the guard-shank 9 with the pins '13 and headed stud 12 projecting through the apertures 18 and 19 in the knife 16 and with the razor edge 1'7 embraced within the U-shaped guard portion 10 and inclined toward the U- shaped guard portion from the hooked end 15 of the guard-shank 9.
  • the prong 1 of the fork is then laid upon the assembled knife and guard with the headed stud 12 projecting through the key-hole slot 20 and with the hook 15 projecting through the aperture 22.
  • the prong 1 is now slipped endwise relative to the knife and guard to shift the narrow portion of the keyhole slot 20 under the head of the stud 12 and to cause the hook 15 prong 1 at one end of the slot 22.
  • the free end of the prong 1 springs downwardly into with the lip 14, as shown in Fig. 3, and prevents accidental displacement of the knife and guard from operative position upon the prong 1.
  • wool or other suitable yam or like material is wound spirally, as at 24, Fig. 1, around the fork member commencing preferably at or near the hook 15.
  • the wool may be wound along the whole length of the blade, or if different colored wools are being used, sufficient of each color to cover the portion of the-pattern being worked, and the knife end of the device is placed under the presser-foot of a sewing machine, upon a suitable lining or backing 25 and stitched thereto by a line of stitches 26 in the gap 3.
  • the fork is partially withdrawn, preferably leaving from five to ten loops on the fork to keep the correct line and position. Further wool is from the prong 1 for rethen wound on the fork and pushed down evenly toward the loops still remaining on the fork, the work being continued in this manner to the end of the row being worked.
  • a widthwise extension bar 27 of any desired width such as shown in Fig. 9.
  • a bar 27 may be provided at one end with a headed stud 28 received in the key-hole slot 20 and at the other end with a headed stud 28' received in a second key-hole slot 20' in the fork.
  • the bar 27 is also preferably formed with key-hole slots 29, 29' for reception of the headed studs 30, 30 of a second extension bar 31, Figs. 11 and 13, which may be added to the fork, in series with the extension bar 27, to still further increase the width of the device, as may be desirable for certain fringing operations.
  • the device may be built out by the use of such bars, either singly or in series, to practically any desired width within the total range provided.
  • the exten- 130 -sion bar 27 is provided with a series of apertures 22*, 21*, 20*, like the respective apertures 22, 21, 20 in the prong 1, to permit of the attachment thereto of the knife 16 the productionof longer cut loops.
  • the legs 2'? of the extension bars which carry the headed studs are preferably dished slightly, as shown in Fig. 12, to cause such legs to frictionally engage the part to which they are attached, and prevent accidental displacement thereof from operative position.
  • the device may be used either with or without the knife and guard to form either cut or uncut loops of various desiredlengths; there being no part of the device under any condition of use to-snag the yarn during the stripping operation or to impede the free and easy stripping of the yarn from the device following a sewing operation.
  • a device of the class described comprising, a flat forked member having two prongs separated by a stitch-receiving gap, and a distance piece narrower than and pivotally mounted at the free end of one of said prongs and engageable with the other prong by a swinging movement about its pivot.
  • a device of the class described comprising, a fiat forked member having two prongs separated by a stitch-receiving gap, and a distance piece pivotally mounted at the free end of the wider of said prongs and engageable with the narrower prong by a swinging movement about its pivot.
