Abstract A weft carrying gripper for shuttleless looms with stationary weft supply, comprises a lower jaw whose relatively stationary upper surface is adapted to contact the weft. A rigid lever pivoted on the gripper carries a metallic lamina at one end that releasably grips the weft thread between itself and the stationary surface of the lower jaw. The same end of the lever also carries a leaf spring that bears resiliently against the lamina. A further leaf spring at the other end of the lever contacts an adjustable portion of the gripper to swing the lever in a direction to urge the lamina toward its weft-gripping position. That other end of the lever serves as a cam which when depressed releases the weft thread.
A weft carrying gripper for shuttleless looms with stationary weft supply, comprising a jaw stationary relative to the gripper, a rigid elongated lever pivoted intermediate its length on the gripper, a metallic lamina carried by one end of the rigid lever, a leaf spring carried by the same end of the lever and urging the lamina toward said jaw, and means acting on the other end of the lever yieldably to urge the lever in a direction in which said lamina moves toward said jaw, said lamina and said leaf spring being secured to opposite sides of the same said end of said lever.

A weft carrying gripper for shuttleless looms with stationary weft supply, comprising a jaw stationary relative to the gripper, a rigid elongated lever pivoted intermediate its length on the gripper, a metallic lamina carried by one end of the rigid lever, a leaf spring carried by the same end of the lever and urging the lamina toward said jaw, and means acting on the other end of the lever yieldably to urge the lever in a direction in which said lamina moves toward said jaw, said lamina and said leaf spring being secured to opposite sides of the same said end of said lever.
Claim 3
Dependent Claim

A gripper as claimed in claim 1, said acting means comprising a further leaf spring that is carried by said lever and that bears against said lever at both of its ends and is spaced from said lever between its ends, and adjustable means carried by the gripper and bearing against said further leaf spring between its ends to adjust the pressure with which said lamina bears against said jaw.
