20140261123 | VARIABLE TIMING SYSTEM OF A SEWING MACHINE AND METHOD FOR SELECTIVELY ADJUSTING A TIMING OF SUCH A SYSTEM - A variable timing system for a sewing machine is provided comprising a shuttle hook having a hook tip, a first helical gear mounted on the shuttle hook, a lower shaft configured to rotate the shuttle hook in synchronization with a needle bar, and a second helical gear mounted on the lower shaft and capable of engaging with the first helical gear. In accordance with embodiments, at least one of the helical gears is axially movable. The variable timing system may comprise a control device configured to generate a control signal representative of a current sewing situation. A drive force mechanism may receive the control signal and in response, transmit axial movement to the axially moveable helical gear to move the gear into proper position relative to a threaded needle of the sewing machine. | 09-18-2014 |
20140216318 | STITCHING SYSTEM AND METHOD FOR STITCH STOP EMBELLISHMENTS - Aspects and embodiments of the present invention are directed to systems and methods for embellishing fabric.
