Patent number: 9162529Abstract: A lightweight caster is described that is resistant to ingress of debris into a caster bearing. The caster has a monolithic fork having an annular wheel-supporting portion and a chair-supporting portion. The wheel-supporting portion has a pass-through aperture for receiving a retainer. A rotational bearing is supported on the wheel-supporting portion, which supports a wheel rim such that the wheel rotates in the vertical plane. The rim has a pass-through aperture aligned with the pass-through aperture of the fork, and a ring at an inside edge of the bearing to retain the bearing between the rim and the fork and to inhibit debris from contacting the bearing. A retainer retains the rim on the fork and has an aperture aligned with the fork pass-through aperture. The retainer also has a bearing-retaining portion at an outside edge of the bearing to retain the bearing and to inhibit debris from migrating inwardly.Type: GrantFiled: October 31, 2014Date of Patent: October 20, 2015Assignee: Inertia Engineering + Design Inc.Inventors: Raymond J.

Patent number: 8381839Abstract: A bottom-hole assembly for directional drilling incorporates a torque generator with a drive shaft connected to a drill string. The torque generator generates a torque that counters a reactive torque when a drill bit of the bottom-hole assembly is driven. When the drill string is rotated at a static drive speed, a drill tool face of the bottom-hole assembly is stabilized to drill a nonlinear bore segment. When the drill string is rotated at a rotational speed other than the static drive speed the bottom-hole assembly is rotated to drill a linear bore segment.Type: GrantFiled: July 21, 2010Date of Patent: February 26, 2013Assignee: Rugged Engineering Designs, Inc.Inventor: Irwin Rosenhauch

Patent number: 7600734Abstract: An locking assembly structured to removably and automatically secure an umbrella mast or other stanchion to a supporting base including a mounting structure secured to the base in interconnecting relation between the stanchion and the base. The locking assembly is connected to the mounting structure and includes a movable locking member positionable between a locked orientation and a released orientation. The locked and released orientations are respectively and at least partially defined by the locking member disposed into and out of interruptive engagement with a predetermined exterior surface portion of the stanchion on an interior of the mounting structure. Automatic disposition of the locking member between the released and locked orientations is facilitated by an end portion of the locking member configured and structured to both slidingly and interruptively engage the stanchion.Type: GrantFiled: February 7, 2007Date of Patent: October 13, 2009Assignee: TUUCI Engineering and Design, Inc.Inventor: Dougan Clarke
