Abstract: A rotary drill bit for drilling wells in earth formations is produced by a casting technique using a plastic foam, combustible casting form. The bit includes a tapered drill body having a plurality of passageways therein which form jets for introducing liquid between the earth and a plurality of selectively arranged, cutting members extending outwardly from the drill body. The combustible form is molded in a shape substantially identical to that of the drill body. The cutting members are mounted on the form in the selective arrangement thereof, and the assembly of the form and cutting members are then coated with a mold material to form a mold body. A cavity is created in the form for receiving a molding mandrel which defines the longitudinal passageway of the completed bit. Molding pins are introduced through the mold body into the mandrel to precisely hold the mandrel relative to the mold body. The cutting members are precisely held by the mold body after the form is removed by combustion.

Abstract: An automatic saw chain grinder includes a saw chain support mounted for reciprocative movement on a support carriage. A spring urges the carriage in one direction to move a cutter tooth of a supported saw chain into a grinding wheel against the residual pressure of fluid in a first single-acting hydraulic cylinder. Pressurization of the cylinder moves the carriage in the opposite direction away from the grinding wheel. The grinding wheel is spring-biased toward an active, grinding position and moved away from such position by a second single-acting hydraulic cylinder. The first and second cylinders are sized and the respective springs of the carriage and grinder selected such that upon pressurization of the common hydraulic circuit for such cylinders, the carriage retracts the cutter tooth away from the grinding wheel before the grinding wheel retracts from the grinding position.
