Abstract
931,116. Sewing-machines. MEFINA S.A. Jan. 29, 1960 [Jan. 30, 1959], No. 3292/60. Class 112. In a sewing-machine a pivoted feed-control shaft is biased by spring means in one angular direction and carries a first lever, and a second lever connected to the first lever is provided with a follower biased by said spring means into engagement with the inner edge of a cam recess formed in a feed-control wheel for determining the forward feed, movement of the follower into engagement with the outer edge of the cam recess, by means of the first lever, causing reversal of feed. A lever 4 is fixed to a control shaft 2, rotation of which from a middle position determines the stitch length and direction, one end of lever 4 being formed as a handle 5 and the other end being formed with a slot 7. A lever 10 is pivoted on a fixed pin 11 passing through a slot 28 in lever 4. One end of lever 10 carries an adjustable pin 9 disposed in slot 7, and the other end a pin 12 disposed in a cam recess formed in a control wheel 14 pivoted on a fixed pin 13. A spring biases shaft 2 clockwise to engage pin 12 with the inner edge 16 of the cam recess, whereby clockwise rotation of wheel 14 progressively increases the forward stitch length, and counterclockwise movement of lever 4 at any setting of wheel 14 engages pin 12 with the outer edge 27 of the cam recess to produce backward stitching of the same length. Edges 16 and 27 are continued beyond the zero position as edges 161-and 27<SP>1</SP> spaced apart at a distance equal to the diameter of pin 12. Backward stitching may thereby also be controlled by counterclockwise rotation of wheel 14 from the zero position.
