Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
A transporter having a generally rectangular base with sides and a top surface and movable on an inflatable air bearing member and including in combination: carrier means attached to said transporter along opposite sides of said base for engaging a load, said carrier means being pivotable to a position below the top surface of the transporter while the transporter is moving on the inflated air bearing member under and independent of the load; and control means connected to said carrier means for pivoting said carrier means through 180* between a lowered position below said top surface of the transporter and an upper position extending above said top surface while the air bearing member is deflated.
Claim 2
Dependent Claim
115 words
A transporter having a generally rectangular base with sides and a top surface and movable on an inflatable air bearing member and including in combination: carrier means attached to said transporter along opposite sides of said base for engaging a load, said carrier means being pivotable to a position below the top surface of the transporter while the transporter is moving on the inflated air bearing member under and independent of the load; and control means connected to said carrier means for pivoting said carrier means through 180* between a lowered position below said top surface of the transporter and an upper position extending above said top surface while the air bearing member is deflated.
Claim 3
Dependent Claim
156 words
A transporter having a base with a top surface and movable on an inflatable air bearing member and including in combination: carrier means attached to said transporter for engaging a load, said carrier means being positionable below the top surface of the transporter while the transporter is moving on the inflated air bearing member under and independent of the load, and including a pair of longitudinal support blocks mounted on opposite sides of the transporter for pivotal movement about a longitudinal axis; control means connected to said carrier means forraising said carriermeans above said top surface while the air bearing member is deflated; a handle on the reerward end of the transporter; and stop means on said top surface for keeping the load a predetermined minimum distance from said rearward end; and wherein said control means includes a manually actuated lever means located rearwardly from said stop means for lowering and raising said longitudinal support blocks.
