Definitions

  • Fig. 2 is an elevation similar to Figure 1 showing the position of the presser-foot and feed-dog after the left to right shifting movement has been partially executed.
  • Fig. 3 is a plan view of the presser-foot.
  • Fig. 4 is a front elevation of the presser-foot.
  • Fig. 5 is a side elevation and Fig. 6 is a disassembled perspective view of the presser-foot.
  • 1 is the usual needle-bar bearing in which is journaled the usual reciprocating needle-bar 2.
  • a needle-clamp 4 Secured to the needle-bar 2 by the usual set-screw 3 is a needle-clamp 4 having a laterally extending arm 5 to which is pivoted a pawl 6 having a stop '7 and constantly urged in a counterclockwise direction by the coil-spring 8.
  • a plate 9 Secured to the usual presser-bar (not shown) is a plate 9 having an upstanding inclined arm 10 and cross arm 11.
  • Pivoted to the upstanding arm 10 at the pivot point 12 is a swinging frame 13 having a depending portion 14 and inwardly extending projections 15.
  • a ratchet-wheel l6 Rotatably supported upon the upstanding arm 10 is a ratchet-wheel l6 rigidly connected with a cam-element 1'7 having a plurality of circumferentially spaced projections 18.
  • a slide-bar 19 Slidably mounted upon the laterally extending arms 11 of the plate 9 is a slide-bar 19 having a depending portion 20 made integral therewith.
  • the slide-bar 19 is provided with an adjustable eccentric stop 21 and a knurled headed adjustable stop-screw 22.
  • the pawl 6 engages one of the teeth of the ratchet-wheel 16 and advances it one step.
  • the presser-foot in 7 its illustrated embodiment, comprises a shank 23 secured by the screw 60 24 to the depending portion of the slide-bar 19.
  • a soleplate 25' To the shank 23 is pivotally secured a soleplate 25'by means of a pivot-pin 26 which is received by the outstanding lugs 27 on the shank 23.
  • the sole-plate 25 is provided with a groove 28 which receives the pivot-pin 26 and is retained on the shank 23 by the retaining plate 29 having fingers 29' which extend over the pivot-pin 26, the retaining plate being fixed to the soleplate by the screws 30.
  • the sole-plate is free to tilt Vertically relative to the shank.
  • the sole-plate 25 is provided with a rectangular opening 31 at one side of the elongated needle aperture 32 in which is closely fitted a relatively thick rectangular shaped auxiliary presser-member 33 which extends below the work-engaging face of the sole-plate.
  • a relatively thick rectangular shaped auxiliary presser-member 33 which extends below the work-engaging face of the sole-plate.
  • a retaining plate 35 Secured by the screw 34 to the upper face of the auxiliary presser-member 33 is a retaining plate 35 which extends over the sides so of the auxiliary presser-member and engages the upper face of the sole-plate.
  • Secured to the soleplate 25 by the screws 36 is a flat U-shaped spring 37 the free limbs 38 of which engage the upper face of the auxiliary presser-member and urge it downwardly with respect to the sole-plate.
  • My improved presser-foot is designed for use for felling, and in Figures 1 and 2 I have shown a piece of material A folded upon itself as at b and with its edge a inturned making a fold c. As will be observed in these figures the outer surface of the fold 0 contacts the edge 39 of the auxiliary presser-member 33, this edge 39 acting as a guide. It will also be observed that the serrated work-engaging faces of both the aux- .95 iliary presser-member and the sole-plate contact the material thereby firmly gripping it to facilitate the lateral shifting movement of the material by the zigzag attachment. It will be obvious from the foregoing description that the auxiliary presser-member acts as a guide for the material and, being yieldingly urged downwardrelative to the sole-plate, readily adjusts itself to materials of varying thickness.
  • a presser-foot for sewing machines comprising, a shank, a sole-plate having an elongated needle-aperture and pivoted thereto so as to tilt vertically, an auxiliary presser-member carried by said sole-plate and extending below the lower face thereof, said auxiliary presser-member having a smooth vertical edge which acts as a guide, and means for yieldingly urging said auxiliary presser-member downwardly relative to said soleplate.
  • a presser-foot for sewing machines comprising, a shank, a sole-plate pivoted thereto so as to tilt vertically, an auxiliary presser-member extending through an aperture in said sole-plate, said auxiliary presser-member extending below the work-engaging face of said sole-plate and having a guiding edge, and means secured to said sole-plate for urging said auxiliary pressermember downwardly relative to said sole-plate.
  • a presser-foot for sewing machines comprising, a shank, a sole-plateprovided with a needleaperture and pivoted thereto so as to tilt vertically, and having a rectangular recess formed at oneside of the needle-aperture, an auxiliary presser-member located in said opening and extending below the lower face of said sole-plate, and a U-shaped flat spring fixed to said soleplate, the free limbs of which engage the upper acts as a guide.
  • a zigzag-stitching attachment including a presser-foot having a shank and a sole-plate, an auxiliary presser-member carried by said sole-plate and extending below the work-engaging face thereof, said auxiliary presser-member having an edge forming a guide,
  • a presser-foot for sewing machines comprising, a shank, a sole-plate having an elongated needle aperture carried thereby, an auxiliary presser-member carried by said sole-plate, said auxiliary presser-member having a vertical edge which extends below the lower face of the soleplate and acts as a guide, and spring means for urging said auxiliary presser-member downwardly relative to said sole-plate.
