of the carrier in an automobile, it is desirable that the carrier be capable of becoming collapsed for occupancy of considerably less space that it would require in normal distended position. Re-

ferring to Fig. 3, the wheels may bebrought together to the collapsed position shown, simply by displacing the collar 3! and interconnected ends of the members 22,-.upwardly on the central frame fpart M, :the inner most positions of the wheels being determined by their engagement with the'supportll 2. :It will be noted that-whereas normally the wheels "are disposed in substantially wertical :iplanes, when scollapsed together they assume :inwardlydnclined positions by 'rea- ,son of ith'e rigid connections .of the castings a2! withimembers 2i. .fl he carrier assembly may :be further zco'llapsed by releasing the detent :sleeve i3flaanrlpermittingthe handle rod.35 to .drop "down ztoitheiposition appearinginiFig. 3.
