  • Patent number: 4011823
    Abstract: A tufting tool comprising an elongated body, a shuttle mounted on the body for reciprocating movement, an elongated resilient plunger attached to the shuttle, and a needle mounted on the body and having a yarn receiving passage and a plunger receiving passage. The needle includes a first portion attached to the body and a penetrating portion projecting from the first portion and terminating in a relatively sharp point remote from the first portion. The penetrating portion and the resilient plunger are adapted for insertion into and withdrawal from a backing material. The penetrating portion includes a cam for resiliently loading the plunger so that upon complete withdrawal of the penetrating portion from the backing material, the plunger resiliently removes the needle forward relative to the plunger so that the needle can advance along the backing material.
