ABSTRACT:
A fishing assembly for use in retrieving a separated or broken sucker rod from a well comprising a body member having a cavity in which a slide member is disposed therein for reciprocation within the body member. An entrance port is formed in the lower end of the body member so as to openly communicate with the cavity, and an elongated, longitudinally slot is formed in one side portion of the body member. A substantially arcuate-shaped internally disposed shoulder is supported by the body member substantially adjacent the entrance port so as to be opposite and in a facing relationship with the longitudinally extending slot of the body member. The slide member is connected to the body member via the slot so as to be reciprocably movable along the cavity axis of the body member from a lower position to an upper position. The slide member is biased in the lower position so that the slide member (when in the lower position) and the shoulder cooperate to capture a joint end of a separated rod. A tubular collet support barrel extends from the upper end of the body member, the tubular collet support barrel having a bore extending therethrough which is axially aligned with the cavity of the body member. A frustoconical surface is formed at the end of the collet support barrel adjacent the body member; and a collet is positioned within the bore of the collet support barrel for receiving and capturing a portion of the rod. The collet, which is biased toward the lower portion of the bore, is comprised of a plurality of depending fingers upon which a mating frustoconcial surface is formed so that a straight rod to can be gripped by the collet by placing such rod in the collet and drawing the collet into the lower end of the collet support barrel by an upwardly directed force on the assembly.
