The support bracket assembly has a top wall, at least two pairs of top bracket holes with top threads, top bolt supports, a lateral wall, at least three pairs of lateral bracket holes with lateral threads, lateral bolt supports, internal walls, internal reinforcement walls, and a central wall. The side cover board has a plate having a plate top edge and a plate bottom edge, first and second lateral holes, and first and second lateral bolts. The top cover board has an elongated plate, a bottom face having hexagonal cells, first and second top holes, first and second top bolts, and an elongated lip.

Abstract: A head component for an anchor assembly for mounting a load bearing track to a hanger component attached to an overhead structure (e.g. a ceiling or ceiling structure), the track comprising a rail element and a mounting element, the mounting element comprising one or more retaining formations, each retaining formation defining a holding cavity and an (cavity) opening communicating with the holding cavity, the holding cavity being sized larger than the (cavity) opening communicating therewith, the head component comprising a support member and a flarable member, the flarable member being attached to and flarable from the support member, the head component being sized and configured such that the head component is able to pass through the (cavity) opening into the holding cavity wherein the flarable member is able to flare (i.e.

Abstract: In an overhead electric traction system, an overhead contact wire is enclosed throughout its length within an elongate protective cover of resilient electrically insulating material. The cover is secured to the contact wire, is symmetrical about a longitudinally extending vertical plane passing through the axis of the contact wire and includes a pair of transversely extending base walls which underlie and are spaced from the contact wire and abut in the vertical plane. When engaged by a transversely extending elongate current collector carried by a travelling vehicle, the base walls are deflected upwardly and outwardly away from one another to expose the running surface of the contact wire and permit the current collector to effect electrical contact with and collect current from the contact wire; after passage of the current collector, the base walls return to their original undeflected positions so that the contact wire is again enclosed within the cover.

Abstract: The electrical collector unit (41) and the overhead conductor entrance (26) are designed so that four collectors (63, 64, 66, 67) can properly enter the conductor slots (18, 19, 21, 22) without manual assistance and with the vehicle, not shown, carrying the collection unit (41) traveling at near a walking speed. Two collector subassemblies (42, 43) are mounted on the vehicle, not shown, each of which carries two collectors and includes spring biased parallel links (73, 74, 76, 77) between a pair of pivot posts (71, 86), a guide roller (61) engageable with side walls (28, 29, 36, 67) of the entrance chute (26) and equalizer beams (134, 136) supporting the collectors (63, 64 or 66, 67).

Abstract: A rail vehicle is disclosed for use on an elevated electric rail system having a lower rail below the vehicle and an upper rail above the vehicle. The vehicle includes a pair of lower wheels having independently rotatable flanges rollably carrying a vehicle cab along the lower rail and an upper wheel having independently rotatable flanges rollably engaging the upper rail. Electric motors, energized through contacts carried on the vehicle by an electric circuit associated with the upper rail, are drivingly connected through drive belts to the respective lower wheel to propel the vehicle along the rail system. The vehicle also includes a clamping rail brake carried by a vehicle which is engagable on the lower rail, and a vertically and laterally extendable servo system secured to the vehicle and carrying the upper wheel.

Abstract: A power distribution system for rail vehicles comprising a flexible resilient conduit for protecting a first electrical conductor fixed in a crowned resilient encasing slotted to receive a second electrical conductor which surrounds the flexible conduit and a second electrical conductor having first lubricating and conducting inserts for improving the electrical contact between the first and second conductors and reducing the friction between the two conductors and second non-conductive lubricating inserts for reducing friction between the second conductor and the resilient encasing.

Abstract: A trolley busway housing has a generally T-shaped top portion which stiffens the housing to provide improved bending resistance and also provides a continuous top flange on which hangers can be clamped.

Abstract: A protective housing is provided for electrical rails and the like, namely, reaction (secondary) rails and slide pick-up lines for operating electro linear propulsion motors for monorail vehicles. The new and improved housing is of simplified construction and enables comparatively large protective plate members to be assembled in the form of a tight housing on elevated monorail structures. The protective plates may be readily removed and slidingly displaced to expose the normally protected electrical components for maintenance, replacement or repair.
