Abstract

670,767. Road vehicle couplings. MARCHETTI, A. Dec. 9,1949 [Dec. 10, 1948], No. 31690/49. Class 103(v) An attachment for coupling a twowheeled trailer to a bicycle or like vehicle comprises an elongated element having the profile of a semi-circle with its ends adapted to be fastened to the trailer and guide members slidably supporting the elongated member and adapted to be fixed on the frame of the bicycle, said guide members being positioned between the front and rear wheels of the latter and below the top of said rear wheel. In one embodiment, of which Fig. 1 is an underneath view, a semi-circular member 3 is attached to a trailer 2 and is engaged by rollers 5 mounted on a bracket 4 carried by a cycle 1. It is so arranged that the centre of the semi-circle formed by the member 3 approximately coincides with the centre of the rear wheel 6. This arrangement obviates unbalancing moments on the towing vehicle due to inertia forces applied by the trailer. The plate 4 may be attached by members 9 to the saddle at 10.
