Abstract
239,568. Arbon, P. May 5, 1924. Bore-hole apparatus.-Jars for use with well &c. drilling apparatus, and comprising a head section insertible within a socket section, are made by placing within the socket section in. sert means of a length substantially equal to the stroke of the jar and then shaping the heated portion of one of the sections so as to enter space unoccupied by the insert means and the other section. In Figs. 1 and 2, both sections are substantially completed except for the formation of the head of the head section, an insert K is placed in the slotted portion of the socket section, and the latter is inserted in a cylinder P; the reduced end ) of the head section is then 'heated and is forced by hydraulic pressure against the insert K so as to become upset and form a T-head J. In Fig. 5, enlargements I are provided at the end of the socket section, leaving an enlarged opening Q; the enlargements L are heated, the head section introduced into the socket section, inserts N are positioned, and the enlargements L are closed around the head seotion by hammering.
