Abstract
A manually driven stitcher or sewing machine. A lever of the stitcher is manually pivotable through an arc to reciprocate a stitching mechanism. When pivoted through the arc, the lever also actuates a clamping assembly, an article advancing mechanism, and a stitching material supplying assembly. The stitcher or sewing machine of the present invention may be used to manually stitch a variety of materials including heavier ones such as leather, nylon strapping, plastic, and rubber.
Claims26
A manually actuated stitcher, comprising:
- a frame having a stitching table on which an article is placed for stitching;
- a lever coupled to the frame and manually pivotable through an arc;
- a needle for stitching the article;
- a drive mechanism coupled to the lever and the needle for converting angular movement of the lever into reciprocatory movement of the needle, the needle moving toward the stitching table of the frame when the lever is pivoted in a first lever direction and away from the stitching table of the frame when the lever is pivoted in a second lever direction;
- a clamping assembly for retaining the article on the stitching table of the frame, the clamping assembly moving away from the stitching table of the frame during a first portion of the arc through which the lever is pivoted in the first lever direction and moving toward a position adjacent the stitching table of the frame during a second portion of the arc through which the lever is pivoted in the first lever direction;
- and
- an advancing mechanism indexing the article along the stitching table of the frame while the clamping assembly is moved from the position adjacent the stitching table of the frame.
4 more elements
A manually driven stitcher, comprising:
- means for supporting an article to be stitched;
- means for stitching the article;
- advancing means for indexing the article during each stitching cycle;
- lever means coupled to the stitching means and advancing means for convening angular movement of the lever means into reciprocatory movement of the stitching means and lateral movement of the advancing means;
- and
- clamping means for retaining the article on the supporting means during a portion of the stitching cycle, wherein the lever means is coupled to the clamping means to control actuation of the clamping means during pivoting of the lever means through an arc, the clamping means moving away from the supporting means during pivoting of the lever through a first portion of the arc and moving toward a position adjacent the supporting means during pivoting of the lever through a second portion of the arc.
