Abstract:
An apparatus for stitching fabric to produce a quilted fabric comprising:a needle plate for supporting the fabric;a presser plate located at a first position above the needle plate and supported for linear motion;a needle located above the presser plate and supported for linear motion;a needle rocker shaft mounted for rotational motion and rotationally oscillating through angular displacements, the needle rocker shaft being mechanically connected to the needle and imparting a reciprocating motion to the needle in response to the angular displacements of the needle rocker shaft;a presser plate rocker shaft mounted for rotational motion, the presser plate rocker shaft being mechanically connected to the needle rocker shaft and imparting a reciprocating motion to the presser plate in response to the angular displacements of the needle rocker shaft, the presser plate rocker shaft further having an output shaft being movable from a first to a second relative angular position with respect to an input shaft, thereby locating the presser plate at a second position with respect to the needle plate and permitting quilts of different thicknesses to be stitched.
