Latest Patents

Crisler's latest patents include a "Front Roller Feeder" and a "Thread Handling System for a Sewing Machine." The Front Roller Feeder is a fabric feed mechanism that features a forward feed roller located ahead of the stitch forming area and a rear feed roller positioned behind it. This design ensures that the fabric is fed to the stitch forming instruments in a relaxed and unstretched condition. The mechanism includes independently applied downward pressure to both feed rollers, and the forward feed roller is raised along with the presser foot. This innovative approach guarantees that the top layer of fabric is fed under the presser foot rather than riding up the front roller.

The Thread Handling System for a Sewing Machine introduces a new thread control mechanism. It includes a second movable needle thread control secured to the upper end of the needle bar, from which the thread extends to the needles. Additionally, a first movable needle thread control eyelet is operatively connected to the needle bar, allowing it to reciprocate vertically in synchrony with the first movable needle thread control. This system also features stationary needle thread eyelets that are adjustably mounted on the exterior of the sewing machine, through which the needle thread extends.
