Claim 4
Dependent Claim
53 words
A load mover as in claim 1, wherein said lifting means for raising and lowering said load comprises a tubular guide structure having a side opening therein, an axially moving tubular member in said guide structure, and means extending into said opening for moving said member and raising and lowering said load therewith.
Claim 5
Dependent Claim
23 words

Claim 8
Dependent Claim
47 words
A load mover as in claim 6, wherein the lower end of said member engages a wheel structure including a load propelling wheel therein, drive means intermediate said power plant and said wheel, and wherein said tubular member defines an opening thru which said drive means extends.
Claim 9
Dependent Claim
50 words
A load mover as in claim 6, wherein said wheel rotates in one direction and propels said load in a forward direction, and said wheel structure includes means to cause said wheel to rotate in said one direction and propel said load in the opposite direction from said forward direction.
Claim 10
Dependent Claim
40 words
A load mover as in claim 6, wherein said wheel structure comprises a platform and a wheel cage hinged thereto and comprising remote leverage means for pivoting said wheel cage about said hinge to move it to a stowage location.
Claim 11
Dependent Claim
100 words
A mover for a vehicle, comprising in combination, a. a frame common to said mover and said vehicle, b. at least one power driven wheel unit supporting said frame from the ground, c. a power plant supported on said frame and outputing power in one direction of movement, d. a lifting unit for raising and lowering said frame, e. a lifting unit for stowing said wheel, f. coupling means between said power plant and said power driven wheel, g. and transmissionless means to reverse the direction of power travel of said wheel unit while maintaining said one direction of movement.
Claim 12
Dependent Claim
100 words
A mover for a vehicle, comprising in combination, a. a frame common to said mover and said vehicle, b. at least one power driven wheel unit supporting said frame from the ground, c. a power plant supported on said frame and outputing power in one direction of movement, d. a lifting unit for raising and lowering said frame, e. a lifting unit for stowing said wheel, f. coupling means between said power plant and said power driven wheel, g. and transmissionless means to reverse the direction of power travel of said wheel unit while maintaining said one direction of movement.
Claim 13
Dependent Claim
