Abstract: 1,091,028. Sewing machines. MEFINA S.A. Oct. 18. 1966 [Nov. 8, 1965], No. 46514/66. Heading D1G. A zig zag sewing machine comprises a series of cams mounted on a driving shaft, a follower carried by an oscillatory slide for selective engagement with the cams upon movement of the latter along the driving shaft, a member bearing against the slide for transmitting the oscillation thereof to the needle bar gate, an amplitude adjustment lever turnable by means of a knob thereon to vary the position of said member along the slide, said knob being carried by a spindle, rotation of which by the knob serving to shift the cams along the driving shaft. An arm 8, pivoted at 9 to a lever 10, has a longitudinal surface 7 slidably engaged by one end 6 of a connecting rod 4 pivoted at its other end to a needle bar gate 2. The length of connecting rod 4 may be varied by turning an eccentric pin 11. A spring 31 acts on gate 2 to bias end 6 against surface 7 and thereby a follower 24 on arm 8 against one of a pack of cams (25), (26), (27) slidably keyed to a driving shaft 17. An axial slot 23 at end 6 is engaged by a pin 22 on one arm 21 of a lever 20 pivoted on shaft 17. The other arm 32 journals an axially-slidable and inwardly spring biased spindle 34 which passes through a slot 36 in the machine frame 13 and carries a knob 35, manipulation of which serves to swing lever 20 for varying the position of end 6 along surface 7. An arm 56, pivoted at 55 to arm 32, engages one side of a four-sided cam 59 rigid with spindle 34, and is formed with a pair of lugs 57 engaging the lowest cam (27). A pin 43, transversely carried by spindle 34, normally engages a vertical groove 45 in arm 32, when follower 24 engages the highest cam (25) and lever 20 is turnable to engage pin 43 selectively in one of a series of notches 37 formed in a plate 38 pivoted at 39 and biased outwardly by a spring 40. If spindle 34 is turned to its leftmost position and drawn outwardly, a washer 48 fixed thereon enters a recess 51 in frame 13 to disengage pin 43 from groove 45. Spindle 34 may then be rotated axially through 90 degrees and released, when pin 43 enters a horizontal groove (46) in arm 32 and spindle 34 can be moved freely in slot 36. If spindle 34 is rotated a further 90 degrees, the third side of cam 59 raises arm 56 to engage follower 24 with the middle cam (26), and a yet further rotation of 90 degrees serves to engage follower 24 with the lowest cam 27.

Abstract: A thread-cutting device comprises a rod provided with a head portion defining an inner circular stop having a cutting edge, each side of which interfaces a slider member, the slider members being concentrically mounted on the rod. A thread introduced between the head and the end of the slider member in contact with the head is retained between the head and the end of the slider member while it passes over the stop and is cut.

Abstract: A pre-assembled sub-assembly of a plate carrying a needle bar on an oscillable cradle is mounted in a head at the free end of the upper arm of a zig-zag sewing machine. The upper edge of the plate is pivotally suspended from and slidable along a transverse bar. The plate is angularly fixed with the bore of a member on the needle bar in alignment with and receiving a gudgeon of a crank rod driven by the principal shaft of the machine, and is fixed on the bar to align the needle bar for cooperation of the needle with a shuttle hook.

Abstract: A sewing machine adapted to be mounted in a support member, comprising a column mounted on a lower frame member having a free arm portion extending therefrom, said column carrying an upper arm disposed generally parallel to the free arm portion and terminating in a head in which a drive mechanism of a needle carrying bar is provided, said lower frame member being pivotally connected to a casing by means of at least two support members pivoted at one of their ends to the frame member and pivoted at their other ends to the casing, characterized in that said support members connect said lower frame member to said casing in such a manner as to permit displacement of the machine with respect to the casing between a first position in which the lower framework member and the free arm are housed in said casing, with their upper faces being generally at the level of the upper edge of the casing, and a second position in which the free arm is on the elevated position above the casing.
