Publication number: 20200325973Abstract: A gearless differential for distributing power from a motor to two follower shafts with ends connected to opposite wheels and to opposed outer disks held in position with a journal mounted casing having corresponding identical regular polygonal raceways with asymmetric sections surrounding a central drive disk there between with equidistant radial slots each holding one cylinder or roller bearing to radially reciprocate as they race along the raceways in a slippage mode where one wheel loses traction; and in a drive mode where the central drive disk power input drives both outer disks connected to the two follower shafts transferring torque evenly to both wheels so there is no movement of the cylinders or roller bearings in the raceways.Type: ApplicationFiled: April 11, 2019Publication date: October 15, 2020Applicant: Team, Inc. dba Tool Engineering & Manufacturing CompanyInventors: Paul G McKinnon, Lane McKinnon

Patent number: 10794016Abstract: A concrete curb forming and extruding apparatus with wheel adjustment locks, and an adjustable slip form system shaping cementitious material into a continuous curb forced there through by an extruder which receives materials stored in a hopper with dasher. The extruder has a rotary trowel compacting member which continually forces material from the hopper into compressed concrete passing through an adjustable slip form to fill the same and form differing shaped continuous curbing underneath fences or against vertical surfaces or conventional curbing, depending upon the slip form setting.Type: GrantFiled: October 27, 2018Date of Patent: October 6, 2020Assignee: Team Inc.Inventors: Paul G McKinnon, Lane McKinnon

Publication number: 20140105683Abstract: A manually operable and steerable curb extrusion device for extruding curb, barrier, wall, gutter or the like from concrete, cement or some other moldable building material. The curb extrusion device has a segmented vibrating hopper into which building materials are placed to fall onto a plurality of tapered counter rotating vibrating augers which compact and force the building material through an extrusion mold where it is shaped before extrusion; the number of augers adjustable and selected to provide the amount of building material required to be extruded.Type: ApplicationFiled: October 11, 2012Publication date: April 17, 2014Inventor: Paul G. McKinnon

Patent number: 8303450Abstract: An eccentric dual stepping gear roller bearing system, which consists of an input shaft and an output shaft associated with a gear ring holding an exterior row of equally spaced ball bearings, an output gear with an interior row of lesser diameter with fewer equally spaced ball bearings held at a different plane relative the exterior row, and at least one stepping gear with exterior and interior stepping gears having differing radii joined off-set on top of one another and eccentrically mounted on the drive shaft to act on the interior and exterior rows of roller bearings, which act as gear teeth to rotate the output gear to reduce shaft output.Type: GrantFiled: July 19, 2010Date of Patent: November 6, 2012Inventor: Paul G. McKinnon

Patent number: 7025367Abstract: An adjustable air cushion bicycle seat hydraulic ram system mounted within the seat post of a bicycle with one end of the ram attached to the bicycle seat, and the other end of the ram in communication with an internal reservoir associated with an adjustable pressurized air/oil reservoir to selectively fill the internal reservoir with a pressurized air column to form an air cushion within the ram to provide the desired ride cushion.Type: GrantFiled: October 8, 2003Date of Patent: April 11, 2006Inventor: Paul G. McKinnon

Patent number: 6854540Abstract: A track vehicle employing a rail track system attached to the sides of the frame of a track vehicle having a continuous track driven by pneumatic tires mounted to the frame proximate each end of the rail system along such that triangular torsion and compression links are mounted to the continuous track such that the apex end slides along the rail and the other ends extending against the track to provides lighter more even ground contact for use on snow and other soft terrain than present track vehicles.Type: GrantFiled: October 7, 2003Date of Patent: February 15, 2005Inventor: Paul G. McKinnon

Patent number: 5527129Abstract: A manually operable and steerable curb extrusion device for extruding curb, barrier, wall, gutter or the like from concrete, cement or some other moldable building material. The curb extrusion device has a hopper into which building materials are placed to fall onto a reciprocating orbital compaction member which compacts, kneads, and forces the building material through an open ended extrusion mold where it is shaped before extrusion.Type: GrantFiled: March 10, 1995Date of Patent: June 18, 1996Assignee: Paul G. McKinnonInventor: Paul G. McKinnon

Patent number: 3936039Abstract: A load-levelling shock absorber unit including a guide piston and piston rod and a first surrounding ride control cylinder, one of which is adapted to be connected to a first sprung mass and the other of which is adapted to be connected to an unsprung mass; an oil reservoir cylinder surrounding the ride control cylinder; and an expansible lift cylinder. The ride control, oil reservoir and lift cylinders are all preferably concentrically arranged and are of the hydraulic type. The piston rod reciprocates within the ride control cylinder and, so long as the piston is centrally positioned within the first cylinder, a lagged control valve does not displace sufficiently to allow repositioning of the outer wall of the lift cylinder.Type: GrantFiled: June 21, 1974Date of Patent: February 3, 1976Assignee: Tropic Industries, Inc.Inventor: Paul G.
