Patent number: 9371624Abstract: An accessory mounting system a swivel assembly has a swivel member defining first and second swivel member connector portions, a swivel housing, and first and second bearings operatively arranged between the swivel member and the swivel housing. The accessory mounting system operatively connects a helical pile driving system having a rotational drive system and at least one clamp system to an accessory. The first swivel member connector portion is adapted to operatively connect the swivel member to the drive system. The second swivel member connector portion is adapted to operatively connect the swivel member to the accessory. The swivel housing is adapted to engage the at least one clamp system such that the clamp system may be operated to fix a position of the swivel housing relative to the drive system. The first and second bearings are configured to allow rotation of the swivel member relative to the swivel housing.Type: GrantFiled: July 1, 2014Date of Patent: June 21, 2016Assignee: American Piledriving Equipment, Inc.Inventors: Paul Suver, Dan Miller

Patent number: 8342265Abstract: A system and method for excavating a subterranean formation, according to which a suspension of liquid and a plurality of impactors are passed between a drill string to a body member for discharge from the body member to remove at least a portion of the formation. The flow of the suspension between the drill string and the body member is controlled by an ultra shearing drilling mud in order to prevent the impactors from settling near the bottom of the formation.Type: GrantFiled: February 18, 2009Date of Patent: January 1, 2013Assignee: PDTI Holdings, LLCInventor: Greg Galloway

Patent number: 8113300Abstract: A method and system for excavating a subterranean formation including pumping a fluid through a nozzle such that an exit velocity of the fluid is greater than an entrance velocity of the fluid. A plurality of solid material impactors may be circulated with the fluid through the nozzle. A substantial portion by weight of the solid material impactors has a mean diameter of approximately 0.100 inches or less. The substantial portion by weight of solid material impactors exit the nozzle, contact the formation and rebound into a junk slot.Type: GrantFiled: January 30, 2009Date of Patent: February 14, 2012Assignee: PDTI Holdings, LLCInventor: Gordon Tibbitts

Publication number: 20090223718Abstract: A method and system for excavating a subterranean formation using a fluid comprising pumping the fluid through at least one nozzle such that a velocity of the fluid when exiting the nozzle is greater than a velocity of the fluid entering the nozzle. A plurality of solid material impactors are introduced into the fluid and circulated with the fluid through the nozzle. A substantial portion by weight of the solid material impactors has a mean diameter of equal to or less than approximately 0.100 inches. The fluid is pumped at a pressure level and a flow rate level sufficient to satisfy an impactor mass-velocity relationship wherein a substantial portion by weight of the solid material impactors has a minimum kinetic energy of approximately 0.075 Ft Lbs when exiting the nozzle. The substantial portion by weight of solid material impactors exit the nozzle and contact the formation.Type: ApplicationFiled: January 30, 2009Publication date: September 10, 2009Inventor: Gordon Tibbitts
