Abstract
Abstract The invention contemplates a conveyor table with a plurality of spaced oblique work-supporting rollers, for guiding and conveying sheet material such as sheet paper while urging the same against a marginal side reference. Drive to these rollers is imparted by a single belt at one marginal side and engaging a corresponding plurality of belt-driven rolls which are oriented to rotate on axes perpendicular to the path of belt movement. Each belt-driven roll has a keyed or universal-joint connection to its corresponding work-supporting roller.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
197 words
In a conveyor table of the character indicated, spaced elongate frame members and a plurality of conveyor rollers rotatably mounted on frame-based spaced parallel conveyor-shaft members extending between said frame members and rigidly secured to one of said frame members, said roller shaft members being oblique to the elongation of said frame members, an elongate marginal guide carried by one of said frame members at an elevation to marginally guide an article conveyed by said rollers in a given longitudinal conveying direction, said roller shaft members forming with said guide an acute angle which is open toward the destination of conveyance in said direction, beltdrive means including a plurality of belt-driven rolls on framebased drive-roll shaft members normal to the said direction of conveyance and rigidly secured to the other of said frame members, adjacent ends of corresponding conveyor-shaft and driveroll shaft members being connected to each other, there being for each conveyor roller a separate belt-driven roll and coupling means keying one axial end of the conveyor roller to the adjacent axial end of the belt-driven roll, and a single drive belt having a longitudinal course and driving a plurality of said belt-driven rolls in common.
Claim 2
Dependent Claim
197 words
In a conveyor table of the character indicated, spaced elongate frame members and a plurality of conveyor rollers rotatably mounted on frame-based spaced parallel conveyor-shaft members extending between said frame members and rigidly secured to one of said frame members, said roller shaft members being oblique to the elongation of said frame members, an elongate marginal guide carried by one of said frame members at an elevation to marginally guide an article conveyed by said rollers in a given longitudinal conveying direction, said roller shaft members forming with said guide an acute angle which is open toward the destination of conveyance in said direction, beltdrive means including a plurality of belt-driven rolls on framebased drive-roll shaft members normal to the said direction of conveyance and rigidly secured to the other of said frame members, adjacent ends of corresponding conveyor-shaft and driveroll shaft members being connected to each other, there being for each conveyor roller a separate belt-driven roll and coupling means keying one axial end of the conveyor roller to the adjacent axial end of the belt-driven roll, and a single drive belt having a longitudinal course and driving a plurality of said belt-driven rolls in common.
Claim 3
Dependent Claim
25 words
The conveyor table of claim 1, in which, for each belt-driven roll and its corresponding conveyor roller, the shaft members are fixed to each other.
Claim 4
Dependent Claim
23 words
The conveyor table of claim 1, in which the belt-driven rolls are positioned at the ends of conveyor rolls remote from said guide.
Claim 5
Dependent Claim
25 words
The conveyor table of claim 1, in which each roll and its associated roller are independently mounted to their associated shaft members on antifriction bearings.
Claim 6
Dependent Claim
25 words
The conveyor table of claim 1, in which said coupling means comprises dog-clutch means comprising coacting elements associated with each roll and its associated roller.
Claim 7
Dependent Claim
45 words
The conveyor table of claim 5, in which each said dog-clutch means includes a prismatic coupling block loosely carried by associated shaft members for rotation on the respective fixed axes of the associated roll and roller and engaged by the coacting elements of said dog-clutch.
Claim 8
Dependent Claim
32 words
The conveyor table of claim 2, in which each pair of associated shaft members comprises a single fixed shaft, bent at said coupling means to define the respective roll and roller axes.
Claim 9
Dependent Claim
28 words
The conveyor table of claim 1, in which said belt-driven rolls are of a material selectEd for a relatively high coefficient of friction with resepct to said belt.
Claim 10
Dependent Claim
33 words
The conveyor table according to claim 3, in which an elongate dust guard is carried by the frame member adjacent said belt-driven rolls and is positioned in vertical registry over said belt-driven rolls.
Claim 11
Dependent Claim
131 words
A conveyor table, comprising spaced elongate parallel frame members and a plurality of like longitudinally spaced fixed shaft means rigidly secured at both ends of said frame members, each shaft means including a conveyor-roller supporting portion and a drive-roll supporting portion, the conveyor-roller supporting portions being fixed at the same acute angle to one frame member and the drive-roll supporting portions being fixed at a right angle to the other frame member, conveyor rollers rotatably mounted on the conveyor-roller supporting portions and drive rollers rotatably mounted on the drive-roll supporting portions, coupling means keying adjacent axial ends of the conveyor roller and drive roll mounted on each shaft means, and a single drive belt having a longitudinal course in the alignment of said drive rolls and driving the same in common.
Claim 12
Dependent Claim
131 words
A conveyor table, comprising spaced elongate parallel frame members and a plurality of like longitudinally spaced fixed shaft means rigidly secured at both ends of said frame members, each shaft means including a conveyor-roller supporting portion and a drive-roll supporting portion, the conveyor-roller supporting portions being fixed at the same acute angle to one frame member and the drive-roll supporting portions being fixed at a right angle to the other frame member, conveyor rollers rotatably mounted on the conveyor-roller supporting portions and drive rollers rotatably mounted on the drive-roll supporting portions, coupling means keying adjacent axial ends of the conveyor roller and drive roll mounted on each shaft means, and a single drive belt having a longitudinal course in the alignment of said drive rolls and driving the same in common.
Claim 13
Dependent Claim
52 words
A conveyor table according to claim 11, and including an elongate side-margin guide carried by said frame at an elevation to marginally guide an article conveyed by said rollers in said direction, the roll-supporting portions of said shaft means forming with said guide an acute angle which is open in said direction.
