Abstract
Abstract A system for handling plate glass and for cutting same. The system includes a self-propelled apparatus on tracks movable to positions adjacent selected bins, containing the substantially vertically disposed glass, located adjacent the tracks. The apparatus includes a tiltable top assembly for tilting to a substantially vertical loading position for loading the glass from the selected bin, and includes power-actuated retrieving means for attachment to the glass to pull the glass from the bin to the top assembly. After loading, the top assembly is moved into a horizontal position. The apparatus includes means for scoring the glass by a single operator shoving a carriage means across a bridge means to the other side of the apparatus where there is located bumper means for returning the carriage means to the operator''s side of the top assembly and trip means for disengaging the cutter means from the glass.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
207 words
In a plate glass cutting apparatus including a top assembly having a top surface, a first side and an opposite second side, means for cutting glass resting on said top surface comprising bridge means including first rod means extending across said top assembly from said first side to said second side, carriage means freely movably mounted on said first rod means for free movement by hand from said first side to said second side of said top assembly, trip means on said second side of said top assembly, bumper means on said second side of said top assembly for engagement by said carriage means to move said carriage back from said second to said first side, glass cutter means, head means for movably supporting said cutter means from said carriage means for movement between a disengaged position relative to the glass on said top assembly and an engaged position relative to the glass on said top assembly, and actuating means operably coupled to said head means for moving said glass cutter means into said engaged position and for engaging said trip means when said carriage means is on said second side of said top assembly to cause said glass cutter means to move into said disengaged position.
Claim 2
Dependent Claim
207 words
In a plate glass cutting apparatus including a top assembly having a top surface, a first side and an opposite second side, means for cutting glass resting on said top surface comprising bridge means including first rod means extending across said top assembly from said first side to said second side, carriage means freely movably mounted on said first rod means for free movement by hand from said first side to said second side of said top assembly, trip means on said second side of said top assembly, bumper means on said second side of said top assembly for engagement by said carriage means to move said carriage back from said second to said first side, glass cutter means, head means for movably supporting said cutter means from said carriage means for movement between a disengaged position relative to the glass on said top assembly and an engaged position relative to the glass on said top assembly, and actuating means operably coupled to said head means for moving said glass cutter means into said engaged position and for engaging said trip means when said carriage means is on said second side of said top assembly to cause said glass cutter means to move into said disengaged position.
