    摘要: A Y-connect fastener (210) is provided for firmly fastening ceiling fan blades (26) to mounting brackets (20). A plurality of protuberant members (32) extend upwardly from the mounting brackets (20), and have head portions (72) and shank portions (74) which fit through apertures (62) in the ceiling fan blades (26). The fastener (210) has an upper surface (214), a lower surface (216), and peripheral edge portions (220) extending between the upper and lower surfaces (214, 216). Openings (224, 226) are formed in the peripheral edge portions (220) in alignment for sliding the opening (226) over one of the shank portions (74), and then rotating the fastener (210) to twist the two openings (224) around two of the shank portions (74), pressing the fastener (210) between the head portions (72) of the protuberant members (32) and the upper surface of ceiling fan blade (26).

    摘要: A rotary plate fastener (24) is provided for firmly fastening ceiling fan blades (26) to mounting brackets (20). A plurality of protuberant members (32) extend upwardly from the mounting brackets (20), and have respective head portions (72) and shank portions (74) which fit through apertures (62) in the ceiling fan blades (26). The rotary plate fastener (24) has an upper surface (36), a lower surface (38), and peripheral edge portions (42) extending between the upper and lower surfaces (36, 38). Openings (46) formed in the peripheral edge portions (42) are aligned for registering adjacent to the shank portions (74) of the protuberant members (32), and then the rotary plate fastener (24) is rotated to twist the openings (46) around the shank portions (74) and press the rotary plate fastener (24) between the head portions (72) of the protuberant members (32) and the upper surface of ceiling fan blade (26).

    摘要: An improved boom (24) for a sliding boom delimber (10) is disclosed formed from a prestressed, conventional I beam (28). A first segment of a cable bundle (70) extends from the grapple head (36) and is secured adjacent the lower flange (32) of the I beam (28). The second segment of the cable bundle (70) is inside and carried by an energy chain (74) and includes first and second, inversely related, linear portions interconnected by a third, C-shaped portion. A sag plate (60) is coextensive with the first segment and located on the opposite side of the first segment than the lower flange (32) for preventing the first portion from sagging and engaging the first segment. Sides (50, 52) extend from the outer edges of the I beam flanges (30, 32) for partially enclosing the energy chain (74). Supports (42, 54, 62) are provided for reinforcing the I beam flanges (30, 32), the sag plate (60), and a side plate (40) extending between the other edges of the flanges (30, 32) on the opposite side of the I beam (28) from the energy chain (74).
