Definitions

  • Cylinder bed. sewing machines are most cornmonly pro vided with work feeding'mechanisms which operate to carry a work fabric across the. cylinder bedofthemaq. chine.
  • the majority of sewing operations'to beperformed on a cylinder bedfsewing machine involve applying stitches to a previously formed tubular articleffonwhich pur-g .pose an across-the-ann-feed is essential.
  • Another stitching operation, howeven-which is peculiarly within the capabilities of a cylinder bed sewing machine involves the formation of a tubular article from a flat piece of a sewing machine attachment of the type having a top feeding mechanism. 1
  • Fig. 1 represents a front elevational view of a sewing machine having an attachment applied thereto in accordance with my invention.
  • Fig. 2 represents a reduced left end elevational view of a portion of the sewing machine and attachment of Fig. 1.
  • Fig. 3 represents an enlar tachment
  • Fig. 4 represents an enlarged left of the attachment fastening means.
  • 11 indicates generally a sewing machine having acylinder bed ,12 which is adapted to accommodate tubular articles.
  • the sewing ed top plan viewof the atmachine illustrated in the drawing is of the type described .in greater detail in the copending U.S. patent application f of Perla, Serial No. 565,122, filed Feb. 13, 1956, to which reference maybe had to gain a complete understanding of the constructive features of the machine.
  • the needle side elevational view 2,944,497 Patented July 12, 1960 I'bar 13'of the sewingmachine which is journaled for endwise reciprocation in the bracket arm 14.
  • a needle'clamp ice 15 Secured to the lower extremity of the needle bar is a needle'clamp ice 15 which accommodates a needle 16 secured therein by,
  • a spring biased presser bar 18 formed at its lower extremity with'a slabbed seat v19 adapted to accommodate a conventional presscr foot which is not used with the present invention.
  • a knurled thumb screw 20 threaded into the presser bar serves in the conventional use of the'machine to'clamp a apresser foot to the presser bar.
  • the sewing machine is fitted with an organized work feeding mechanism (not shown) capable of advancing a 16 work fabric acrossthecylinder 'bed 12.
  • an organizedwork feeding device of thesewa ing machine is not used and, therefore, a feed cover plate is applied-on the-cylinderbed in place of the usual. throat plate.
  • the feed cover plate is somewhat thicker- 20jthan the usualthroat plate and renders the-work feed ing device' of the sewingmachine ineffective.
  • these sewing machines which are equipped with feed dog throw-out devices the 'useof a feed not be essential.
  • V As best illustrated in dicated generally as; israpplied to the sewing machine.
  • the attachment 30, is a work jogging attachment fitted with .a top feedingmechauism and is a modified form 1 ofathat attachment ,'.illustrated and described in the U.S. 30 patentlo'f Ut'z, No.,'2,6 52,01'5, Sept. 15, 1953, towhich reference' may be had. for acornplete disclosure eithe details ofconstruction; of the attachment.
  • the attachment 30 in its. conventional form as disclosed in ,theUtn patent is providedfwith a clamping member '35 welded or otherwise permanently formed asa part of the i attachment name and adaptedto be secured directly to. 'thepresslertbar seat 19 by the knurled th'umb'screw 2.0 so as to. mount, the attachment onthepresser bar inposhl tionto 'feed a work fabric across the work supporting bed of the. sewing machine, that is, to feed the work in the same direction as the work would be fed by the conventional organized feeding mechanism of the sewing machine.
  • the attachment is capable of jogging a work fabric transversely of the direction of feed of the work and thus as mounted on the sewing machine in its conventional form the attachment can zigzag the work as it is fed across the work supporting bed.
  • the presser bar clamping mem ber of the attachment as disclosed in the Utz patent has been removed from the attachment frame and in its place the attachment frame has been formed with an upstanding flange 31 drilled for the reception of a pair of fastening screws 32 which secure the flange 31 to one extremity of an adapter bracket 33 formed at its other extremity with a socket 34 which accommodates the.
  • the socket 34 in the adapteribracket is drilled to receive the knurled thumb screw 20 by which the adapter bracket and thus the attachment is secured'to the sewing machine in a position at right angles to the conventional arrange- I ment of this type of attachment on a sewing machine;
  • the attachment 30' includes an actuating lever 35' of which the free extremity is bifurcated so that in its conventional application to a sewing machine, as dis- 1 closed in the above referred to Utz patent, the actuating lever embraces the shank of the needle clamp screw 17.
