Patent number: 10053873Abstract: A handle assembly for a power tool includes a main handle having a first end configured to couple to the power tool and a handle bar having a first end coupled to the main handle. The handle bar has an isolation bushing positioned at a first vibration dampening point and configured to dampen vibrations transmitted between the main handle and the handle bar. A vibration dampening assembly couples the handle bar to the main handle at a second vibration dampening point and is configured to further dampen vibrations transmitted between the main handle and the handle bar. The vibration dampening assembly includes a collar that encircles the main handle and a pair of annular resilient member positioned between the collar and the main handle.Type: GrantFiled: April 20, 2017Date of Patent: August 21, 2018Assignee: M-B-W, Inc.Inventor: Anthony Grinwald

Patent number: 8202022Abstract: A vibratory percussion rammer includes a gear box, a percussion delivery unit extending downwardly from the gear box, and one or more slide bearings disposed in the percussion delivery unit between adjacent surfaces of reciprocating metal components. The slide bearings are made from a sheet of plastic material that is curved into the shape of a tube having a C-shape in cross section and define an open seam extending the entire length of the slide bearing. Slide bearings according to this design can be disposed in the percussion delivery unit to eliminate some or all of the metal-on-metal contact between reciprocating components, including between the ram and shaft assembly and spring box and the guide cylinder, the spring separator and the spring box, and the shaft of a ram and shaft assembly and an upper end of the spring box. The seam width of any slide bearing is wider than the anticipated width-wise thermal expansion of the slide bearing during normal operation.Type: GrantFiled: January 25, 2011Date of Patent: June 19, 2012Assignee: M-B-W Inc.Inventor: Anthony Grinwald

Patent number: 8057125Abstract: Vibratory percussion rammers and methods of making vibratory percussion rammers are provided. In one example, a vibratory percussion rammer includes a gear box, a percussion delivery unit extending downwardly from the gear box, and one or more slide bearings disposed in the percussion delivery unit between adjacent surfaces of reciprocating metal components. The slide bearings include a sheet of non-metal material that is curved into the shape of a tube having a C-shape in cross section. Slide bearings according to this design can be disposed in the percussion delivery unit to eliminate some or all of the metal-on-metal contact between reciprocating components, including between the ram and shaft assembly, spring box and the guide cylinder, the spring separator and the spring box, and the shaft of a ram and shaft assembly and an upper end of the spring box.Type: GrantFiled: August 6, 2008Date of Patent: November 15, 2011Assignee: M-B-W Inc.Inventor: Anthony Grinwald

Patent number: 7357738Abstract: The present invention relates to a sports support pole, and more particularly to a reinforced support structure for supporting a pole such as a basketball pole or the like. The support structure may include a support bar positioned substantially in the center of the sports pole and may be held in position by one or more spacers. Cement may then be poured into the sports pole, with the spacers holding the support bar in position. Once the cement is cured, the support bar provides reinforcement to the sports pole against tension and shearing forces and the cement provides reinforcement against compression forces. An alternative embodiment provides for three or more support bars positioned at substantially equivalent intervals adjacent to the inner diameter of the sports pole.Type: GrantFiled: August 31, 2005Date of Patent: April 15, 2008Assignee: Russell CorporationInventors: Ronald White, Thomas Strunsee, Anthony Grinwald
