Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
151 words
A multi-station conveyor comprising an elongate endless drive element extending along a path having straight sections and turns connecting said straight sections, motive means effecting longitudinal movement of said drive element along said path, a track extending longitudinally along said drive element and having an upwardly facing bearing surface outwardly of an above said drive element, a carrier mounted on said track for movement therealong, drive element engaging means depending rigidly from said carrier between said track and drive element and normally urged inwardly into driven engagement with said drive element, declutching means inwardly of said track including a deflector for deflecting said engaging means outwardly out of engagement with said drive element for stopping said carrier, and a generally horizontal friction wheel mounted for rotation about a fixed axis centrally of each of said turns for bearing engagement with the inner side of said carrier extension passing along said turns.
Claim 2
Dependent Claim
151 words

Claim 3
Dependent Claim
48 words
A multi-station conveyor according to claim 1, said carrier extension being generally flat and tangent to said path along said turns, and said friction wheels each having a radius approximately equal to the radius of said path and said turns for maximum bearing engagement with said carrier extensions.
