Abstract
A construction for a fire engine body or the like including a body and a rotatable tower mounted on the body, and a continuous wiring connection between the body and the rotatable tower including a large diameter drum mounting a wire ribbon which extends onto a small diameter drum rotatable with the tower whereby multiple rotations of the small drum can be experienced for each rotation of the large drum to thereby permit a continuous wire to extend between the body and the rotatable tower, and a signal arrangement for indicating the amount the tower has rotated from a neutral position.
Claims14
An electrical installation for a rotatable tower comprising a frame, a first drum pivotally mounted on said frame and having a hub portion and an outer surface, means biasing said first drum to a central position, a second drum offset laterally from said first drum, a rotatable member mounting said second drum for turning with said tower, a plurality of wires on said outer surface of said first drum, means for attaching said plurality of wires to said second drum, and means for conducting said plurality of wires from said second drum into said rotatable tower, said first drum having a diameter which is greater than the diameter of said second drum whereby said second drum can rotate a plurality of turns for each turn of said first drum.
An electrical installation as set forth in claim 11 wherein said outer surface in the area of said second opening provides a smooth lip portion.
An electrical installation as set forth in claim 12 wherein said clamp means is located at said smooth lip portion.
An electrical installation as set forth in claim 13 wherein said second drum includes a second outer surface, said ribbon being folded at a right angle to itself on said second outer surface, and second clamp means for clamping said ribbon folded at a right angle to itself to said second outer surface.
A construction comprising a body, a rotatable tower mounted on said body, a tower rotating circuit including continuous wiring connections between said body and said rotatable tower, signal means for indicating the extent to which said tower has been rotated from a predetermined position, an electrical connection in said tower rotating circuit, means for terminating said electrical connection to the tower rotating circuit when said tower has been rotated a given amount from said predetermined position, and means for overriding said means for terminating said electrical connection to the tower rotating circuit.
