Abstract
An angularly configured bracket is mounted at one end portion for pivotal adjustment in a sewing machine into a position of engagement at another end portion with fixed machine structure. A fastener extending through a slot in the bracket while the bracket is so adjusted secures the bracket to the upper end of a fixed post having a rotatable work feed controlling cam thereon, and so stabilizes the post against distortion by a spring biased cam engaging follower.
Claims8
In a sewing machine, a vertical post which is affixed at one end in the machine;
- a rotatable cam for controlling a sewing function, the cam being supported on the post;
- a cam follower which is spring biased for enforced engagement with the cam, and which while so biased against the cam, subjects the post to a bending moment;
- a bracket for resisting distortion of the post, the bracket being angularly configured and being pivotally mounted at one end portion in the machine to permit adjustment of the bracket into a position wherein another end portion is supported against fixed machine structure, said bracket including an elongate slot;
- and a fastener extending through the slot into the upper end of the post for affixing the bracket to the post while said another end portion is against the fixed machine structure.
