Abstract
Abstract A transport or conveyor system for moving materials in a carriage or vehicle having wheels, adapted to ride on parallel rails comprising a parallel rail system including automatic switching, turning and stopping means; a plurality of drive chains or belts disposed between the parallel rails, and a carriage or vehicle adapted to ride on the parallel rails and convey loads of materials, the carriage including a body, rail wheels attached to the body, a carrier wheel to engage the drive chain or belt attached to the body and means for transmitting the motion of the drive chain or belt to the carriage.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
169 words
A system for transporting, comprising: a. a guideway including at least one pair of horizontally spaced parallel tracks; and a rollway having rollers intersecting said tracks from a position lower than said tracks to a position higher than said tracks; and b. a carriage including wheels for engaging said track to allow said carriage to advance along said tracks; a planar portion extending parallel to the rotational axes of said wheels in a plane beneath said wheels, said planar portion having a width less than the space between the parallel tracks and being engaged by the rollers to lift the carriage from said tracks so that the carriage may roll along the rollway at an angle to said tracks, a chain positioned between said tracks for conveying said carriage therealong; sprocket means on said carriage for engaging said chain; uncoupling means for disengaging said sprocket from said chain; and said sprocket means and said uncoupling means being positioned above said planar portion so as not to engage said rollway.
Claim 2
Independent Claim
169 words
A system for transporting, comprising: a. a guideway including at least one pair of horizontally spaced parallel tracks; and a rollway having rollers intersecting said tracks from a position lower than said tracks to a position higher than said tracks; and b. a carriage including wheels for engaging said track to allow said carriage to advance along said tracks; a planar portion extending parallel to the rotational axes of said wheels in a plane beneath said wheels, said planar portion having a width less than the space between the parallel tracks and being engaged by the rollers to lift the carriage from said tracks so that the carriage may roll along the rollway at an angle to said tracks, a chain positioned between said tracks for conveying said carriage therealong; sprocket means on said carriage for engaging said chain; uncoupling means for disengaging said sprocket from said chain; and said sprocket means and said uncoupling means being positioned above said planar portion so as not to engage said rollway.
Claim 3
Dependent Claim
20 words
The system of claim 1, wherein the tracks extend through and past said rollers where said rollers intersect the tracks.
Claim 4
Dependent Claim
80 words
The system of claim 1, wherein the guideway includes at least one additional pair of spaced parallel tracks intersecting and extending at an angle to said initially recited track and wherein said guideway further includes a rotatable turntable disposed between both pairs of tracks, said turntable engaging the planar surface of said carriage to rotate said carriage to align the wheels of said carriage with the additional pair of tracks so said carriage rolls along the additional pair of tracks.
