Abstract
446,307. Well reamers. HAMMER, O., 108, West Whittier Boulevard, Whittier, California, U.S.A. Jan. 23, 1935, No. 2278. Convention date, Jan. 31, 1934. [Class 85] In a well reamer, the body 10 has pockets 13 receiving rolling cutters 14 on pins 16 with offset ends 29, 30. At one end, an integral bushing 21 fits the body of the pin and the offset 29 and at the other end a bushing is provided in two parts 31, 32, fitting the body of the pin and the offset 30 respectively. Bushing 21 and bushing part 31 have flange, with flat sides engaging flats 26, 33, to prevent rotation ; the flats may be formed by milling arcuate grooves and welding metal inserts therein. The bushing part 32 is locked by a transverse pin 36a engaging grooves therein, the pin 36a being locked by a threaded plug. Washers 37, 38 have hooked flanges 40 engaging rebates in the bushing flanges to prevent relative rotation or axial movement. The Specification as open to inspection under Sect. 91 states that the pin mounting may be applied other than to well reamers. This subject-matter does not appear in the Specification as accepted.
