Abstract
A sewing machine assembly includes a sewing machine frame, a main presser bar, and a presser foot assembly. The sewing machine frame includes a frame base, a frame body that extends from the frame base, a frame head coupled to the frame body that extends from the frame body toward the frame base. The main presser bar is mounted to the frame head of the sewing machine frame. The presser foot assembly includes an auxiliary presser bar offset from the main presser bar.
Claims18
A sewing machine assembly comprising:
- a sewing machine frame including a frame base, a frame body that extends from the frame base, a frame head coupled to the frame body that extends from the frame body toward the frame base to define a throat of the sewing machine frame;
- a feed dog assembly including a feed dog mounted to the sewing machine frame to reciprocate horizontally relative to the sewing machine frame;
- a main presser bar mounted to the frame head that extends along a main axis from the frame head toward the frame base;
- and
- a presser foot assembly configured to be changed between an unused configuration associated with a free motion mode of the sewing machine assembly in which the presser foot assembly is spaced apart from the main presser bar and an in-use configuration associated with a fixed motion mode of the sewing machine assembly in which the presser foot assembly is coupled to the main presser bar, the presser foot assembly including:
- an auxiliary presser bar that extends along an auxiliary axis between a first end and a second end spaced apart axially from the first end,
- a presser foot coupled to the first end of the auxiliary presser bar,
- an auxiliary presser bar mount coupled to the second end of the auxiliary presser bar and configured to be selectively coupled to the main presser bar to couple the presser foot assembly to the main presser bar in the in-use configuration so that the auxiliary axis of the auxiliary presser bar is offset laterally and longitudinally from the main axis of the main presser bar to align the presser foot with the feed dog on the frame base.

A sewing machine assembly comprising:
- a sewing machine frame including a frame base, a frame body that extends from the frame base, a frame head coupled to the frame body that extends from the frame body toward the frame base to define a throat of the sewing machine frame;
- a main presser bar mounted to the frame head of the sewing machine frame that extends vertically along a main axis from the frame head toward the frame base and configured to selectively couple to a hopping foot when the sewing machine assembly is in a free motion mode;
- and
- an auxiliary presser bar mounted to the frame head of the sewing machine frame that extends vertically along an auxiliary axis that is parallel to the main axis and configured selectively couple to a presser foot when the sewing machine assembly is in a fixed motion mode,
- wherein the auxiliary axis is laterally and longitudinally offset from the main axis.
