Application October 18, 1944,‘ Serial No. 559,207 13 Claims. 1 ‘ invention relates to monorail traction systems and particularly to trolleys for such sys tems. ‘ ‘ An object of the invention is to provide a sim pli?ed yet highly efficient mechanism'for driving a trolley-suspended carriage along‘ a monorail. Another object is to provide a drive mechanism for a, trolley-suspended carriage that .may be easily adapted to different suspended loads, to assure an adequate but not excessive tractive fric tion' between a drive wheel and a monorail track. Another object is to prevent inan improved manner side sway of a trolley in traveling at mon orail. - (01. 46-216)‘ 2 and have shown a drive-transmitting trolley asso ciated with the motor car, and a mere suspension trolley associated with the passenger cars, said trolleys, however,"having certain novel ‘features in common. - ‘ Describing ?rst the drive-transmitting trolley, a frame 6 which may advantageously be a sheet metal stamping rigidly surmounts the‘car 4 and projects upwardly therefrom, said frame having its lower end portion horizontally bent to form a base 1 bolted to the car as indicated at 8. It is preferred to extend said base forwardly and rear wardly beyond the car 4 and to perforate its ends for engagement by the downturned ends of coupling members 9 welded or otherwise perma Another object is to provide in an improved 15 ‘ nently a?‘lxed to the cars 5. ‘The upper end por manner for securely holding a carriage suspend it a ready removal from the track by means of tion of the frame 6 is of reduced width and hori zontally bent to, form a lug In which journals the upper end of a shaft ll adapted to be driven by a simple control. an electric motor l2 rigidly installed within the . ing trolley engaged with its track, while affording 7 Another object is to utilize monorail trolleys as 20 .car 4. , The motor rigidly carries within said car coupling member for cars of a suspended train. an arched ‘bracket l3 engaged'by the bolts 8 and Another object is to suspend a‘car from an formed centrally with an upstanding bearing ‘ l4 overhead track by trolleys riding the track and j'ournaling the motor shaft Ma. and snugly en-' coupled to the end portions of the car.
