The conventional rapper design is improved to provide longer service without maintenance and easier access at less cost when service is required by, among other things, redesign of the hammer assembly, hammer shaft and lever assemblies, and the hammer assembly housings. Design improvements include the provision of access panels on the housings, a guide and lock mechanism for removing and inserting the hammer assembly out of and into the hammer assembly housing, providing the hammer with a removal, and keyed engagements of hammer shaft assembly components.

Rapper assembly

An electric cable connector device for use with pothead connectors has a base member with a wide lower portion and an elevated portion for maintaining an electrical connection formed by two electrical cables above the ground while permitting the device to move on the ground and thus prevent electrical short, dirt contamination, and inadvertent damage. The base member may also have a first and second leg portions configured for straddling a berm such that the device moves along a berm without entering a roadway. Apertures are formed in the base member for forks of a forklift or for a chain or cable such that the device and connection may be moved. The connectors and/or cables are secured to the base member by clamps. Slide mechanisms may be disposed between the clamps and the base member such that the connectors may be slid apart for inspection and repair while remaining secured to the base member. Cable guides are coupled to the base member and have a channel formed between two curved surfaces to prevent the cable from kinking. The base member may be painted a bright or flourescent color, have reflective material attached, and/or have a flag attached to increase visibility and prevent inadvertent damage.
