Patent ID: 7036341

Claim:
A transfer jack comprising: a main body having: a tip portion with an upper face and a lower face; a stitch loop hooking portion for engaging a stitch loop, said stitch loop hooking portion being formed on said upper face of said tip portion; a stitch loop stopper backwardly extending from said stitch loop hooking portion; and a pair of relief portions on said lower face of said tip portion of said main body in the proximity of said stitch loop hooking portion, said pair of relief portions being shaped and arranged to avoid interference between said transfer jack and a sinker plate at a foremost portion of a front needle bed and a rear needle bed during a racking motion and when said transfer jack is located at an advanced position; wherein said stitch loop hooking portion is shaped so as to be biased toward a base end of said main body from a center of a gap between the front needle bed and the rear needle bed when said transfer jack is located at the advanced position during the racking motion, and wherein a flat bottom portion between said pair of relief portions on said lower face of said transfer jack is located in the gap between the front needle bed and the rear needle bed when said transfer jack is located at the advanced position during the racking motion so that interference with the sinker plate can be avoided, whereby an effective width corresponding to a distance between said stitch loop hooking portion and a tip portion of each of said relief portions of said transfer jack is increased with respect to a height of a hook portion of a knitting needle when the knitting needle enters into the stitch loop from a base end-side of said main body of said transfer jack.
