Definitions

  • Thisinventiom relates to: new and: useful improvements in machines for embroidering sewing and open-work stitching, of the crank type: I
  • machines of this type the presser foot which feeds the fabric is rigidly secured to a presser foot bar, is caused to oscillate about two horizontal axes perpendicular to each other, and is also given a vertical reciprocating motion during which it is guided by a hinge or pivoting piece which is slidable on a verticaltube.
  • pivoting pieces have been constructed in a manner to create inherent disadvantages such as for instance the rapid wear of the piece with the resultant irregularity of the stitching.
  • the present invention relates particularly to improvements in the pivoting piece or element whereby such difiiculties are obviated.
  • Fig. 1 is a side elevational view of the head plate of the machine, provided with the improved device according to the present invention.
  • Fig. 2 is a like view of the hinge or pivoting element according to the invention, and Figs. 3 and 5 are corresponding end elevational and plan views.
  • Fig. 4 is a sectional view taken on the line YY of Fig. 5.
  • Fig. 6 is a sectional view taken on the line ZZ of Fig. 2.
  • Figs. 7 and 8 are respectively elevational and plan views of said hinge or pivoting element.
  • Figs. 9 and 10 are views of the internal member of said pivoting'element in side and end elevation.
  • the hinge G which is extended by the shank I (Fig. 4), is mounted in a bearing element D in which is pivotally' mounted the shank I of the said hinge C.
  • the bearing element D is rigidly secured to the slide of the presser foot P which is givena vertical reciprocating motion.
  • amember E In the interior ofthe-hinge C, which is made incone piecaflis disposed amember E, shown in eievational and plan view in Figs. 9 and 10, it being pierced with a bore of such diameter that it is slidable without play alon the tube B of the machine.
  • the said mem er E is provided with two bosses e e whereof each is pierced with a smooth aperture; said member E is maintained in the interior of the hinge C by means of two screws WV 'W, and for this purpose the shank I of the hinge C is drilled and tapped for the insertion and maintenance of the screw the hinge C is further provided with a tapped boss in which is engaged the screw l/V.
  • the said screws are terminated by smooth cylindrical parts engaging in the respective bosses e e of the member E, which are pierced with smooth holes.
  • the member A must oscillate on the axis XX (Fig. 5), and to this end the hinge C carries two bosses pierced with two smooth holes in which are engaged the respective smooth ends of the screws W WV which are secured in suitable bosses formedon the member A.
  • This device provides an approved suspension on the Gardan principle, and the member A may thus oscillate on the axis X-X or on the axis YY, or on any intermediate axis.
  • the member E serves as a rigid axle for the whole system, since it is adjusted without play upon the tube B, as stated, and this member guides the hinge C; with this arrangement, the hinge C cannot be moved in its own plane, and the desired result will be thus obtained.
  • This device allows the'vertical reciprocating motion of the member C, which is necessary for the functioning of the ma chine.
  • the general pivoting device or hinge when thus arranged, is enabled to oscillate on Furthermore, the efiects of wear will herein be manifest after a much longer time, as
  • a pivoting element commember disposed in said recess and pierced with an aperture having the same diameter as the tube of the machine, bosses provided on said member, and smooth holes formed in said bosses, screws having smooth ends which are engaged in said holes, two other bosses with smooth holes, provided on the said pivoting element, screws having cylindrical ends which are disposed in the said holes, and bosses provided on the said presser 'iootbar', in whichflthe said screws are engaged.
