At least one cross member is affixed between the opposed longitudinal members. The cross member has a number of spaced locking passageways therein. An upright support post assembly is also provided, which is supported by the cros...

A moveable roadway barrier system comprising a number of interconnected barrier sections of substantial length which can be moved to change the direction of traffic flow or for other reasons by a self-propelled or towable vehicle without disconnecting adjacent barrier sections. Barrier sections which have glare screens or other devices protruding above the top of the barrier can be transferred by the system. Existing barrier sections of various lengths and profiles can be retrofitted for transfe...

A movable display assembly for use with a fixed display wall includes a stationary base positioned horizontally in front of and at the lower end of the fixed display wall; a pair of spaced apart parallel tracks extending parallel to the fixed display wall and mounted on the stationary base; a trolley movably mounted on the tracks, each trolley including a plurality of rollers which ride within the tracks and thereby movably support the trolley therealong; an inverted substantially U-shaped rack ...

A moveable enclosure for use in applying a sprayed material on the surface over which the enclosure is moved includes a frame assembly defining a plurality of side walls with rollers for movably supporting the frame. A mesh skirt is supported by the frame adjacent the plurality of side walls and is positioned with its lower edge adjacent the surface. A mesh top canopy is positioned on the top of the frame with its lower edge overlying the upper portion of the skirt to complete the enclosure.

A switch is provided with a moveable contact and contact carrier that significantly facilitates the manufacturing process necessary to make the assembly. The contact carrier is provided with first and second extensions that are generally flexible and associated with each other to provide a gap therebetween. In the preferred embodiment of the present invention, the second extension comprises first and second fingers that extend from the contact carrier. The second extension is provided with protu...

A hoist for raising building board from the ground to working proximity to a structure to which said board is to be affixed, e.g. a ceiling, has an inclined track which in one embodiment may be curved in such a manner as to allow the board to be loaded on a vertically disposed truck and moved upwardly on the track into position in working proximity to a horizontal working plane without bumping or jostling the board against the structure.

A moveable target assembly includes a self-propelled carriage upon which a target is mounted for rolling movement across terrain. Axially flexible track sections are coupled together in an end to end fashion so as to define a prescribed course or path which the target will follow. The track defines a substantially planar surface and is relatively thin so that it lies flat on the surface of the terrain and thus does not present an impediment to other vehicles, infantry troops or the like that des...

A primer mower (A) has an articulated boom assembly (B) connected to it. A mower head (C) is connected with the other end of the boom assembly. This enables the mower head to be positioned substantially parallel with the ground even along embankments and the like. The mower head includes a deck (20) and a downward extending skirt (22). A rotary cutter (16) is rotatably disposed below the deck and extends outward there beyond at a cutter exposing opening (24). A guard assembly (30) is moveably di...
