[ I claim:] [1.] A movable scaffolding apparatus comprising:a. Scaffolding frame means, comprising:i. At least three vertical scaffolding posts having upper and lower ends, said vertical posts having a lower portion above the lower end;ii. Frame brace means rigidly connecting said vertical scaffolding posts; andiii. A foot pad being fixed to the lower end of each of the said vertical scaffolding posts; andb. a wheel support means comprising:i. a wheel and axle assembly; andii. positioning means connecting said wheel and axle assembly to said scaffolding frame means, said position means moves said wheel and axle assembly between an engaged position where said scaffolding frame means rests upon said wheel and axle assembly and a disengaged position where said scaffolding frame means rests upon said foot pads, said positioning means comprises: a pivoting rod having a first end and a second end, the first end of said pivoting rod being pivotally mounted to said lower portion of said vertical scaffolding post, said wheel and axle assembly being fixed to the second end of said pivoting rod, wherein the axle of the assembly constitute an axial extension of said rod; a brace wedge pivotally mounted on said rod and pivoting into engagement with said scaffolding post bracing said pivoting rod in a fixed position thereby resting said scaffold frame means on said wheel support means thereby permitting the frame means to travel on said wheel support means, whereby pivoting said brace wedge out of engagement with said vertical post permits said pivoting rod to pivot freely thereby resting the frame means on said foot pad.
