First Claim
Patent Images
1. A traffic barrier system which provides a safe separation between opposing lanes of vehicular traffic and is capable of being moved across lanes to change the direction of traffic lane flow comprising:
- a plurality of barrier sections, having top, bottom and side surfaces, pivotably connected together adjacent the ends thereof, a vehicle capable of laterally transferring said barrier sections having thereon transfer beam means constructed to provide movement of said barrier sections from one side of said vehicle to the other side as the vehicle travels in one direction;
a pair of longitudinally spaced apart elements attached to said top surface of each barrier section only adjacent the barrier ends;
said transfer beam means and said longitudinally spaced apart elements including roller means rotatably fixed thereto for moving said barrier sections relative to said transfer beam means, the other of said transfer beam means and said longitudinally spaced apart elements including rail means engageable with said roller means;
whereby when said vehicle travels in said one direction, the transfer beam means engage the roller means consecutively for lateral displacement of the barrier sections.

Abstract
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 transfer by the system.

- 2. A traffic barrier system as in claim 20 having an inplace support system which holds the barrier between one and six inches above the roadway surface to allow free flow of surface drainage and to allow the use of marker buttons or reflectors for the demarcation of the lane boundaries comprising two pads of rubber or other materials one each of which is bonded to the underside of the barrier section at or near the end of the barrier section.
