Abstract
A sheet transporter has a rectangularly shaped frame having a sheet receiving surface, a pair of sheet retainers mounted adjacent the top corner of the frame to maintain the sheets toward the sheet receiving surface, laterally moveable sheet support member adjacent bottom corners of the frame and a lifting bail having an adjustable elongated member mounted to the frame with the longitudinal axis of the elongated member and sheet receiving surface of the frame subtending an oblique angle.
Claims10
A sheet transporter comprising:
- a frame having a right side, a left side, a top end and a bottom end to define a sheet receiving surface therebetween;
- sheet retaining means mounted on said frame adjacent each of said right and left sides and adjacent said top end of said frame;
- means mounting said sheet retaining means for moving said sheet retaining means toward and away from the sheet receiving surface;
- means mounting said sheet retaining means for moving said sheet retaining means along a reciprocating path between said top end and said bottom end and for biasing said sheet retaining means in a first direction along the reciprocating path;
- first means acting on said moving means for securing said sheet retaining means in a preselected position relative to the sheet receiving surface;
- second means acting on said moving and biasing means for securing said sheet retaining means at a preselected position in the reciprocating path;
- at least one guiderail mounted adjacent each of said right and left sides of said frame with its longitudinal axis generally parallel to said bottom end;
- a pair of sheet support means each having a sheet supporting surface;
- means including a groove mounting each of said sheet support means for slidably mounting a sheet supporting means on a respective one of said at least one guiderail with the sheet supporting surface of said sheet supporting means generally normal to said sheet receiving surface and parallel to the bottom edge of said frame;
- and
- means for securing each one of said sheet support means in a preselected position on its respective one of said at least one guiderail.

A sheet transporter comprising:
- a frame having a right side, a left side, a top end, and a bottom end to define a sheet receiving surface therebetween:
- sheet retaining means mounted at each of the right and left sides adjacent said top end to maintain the sheets toward the sheet receiving surface of said frame;
- said sheet retaining means includes:
- a plate;
- means for mounting said plate to move along a first reciprocating path between the top and bottom ends;
- a sheet engaging member mounted to said plate and moveable toward and away from said sheet receiving surface;
- means for securing said sheet engaging member in a preselected position relative to said sheet receiving surface;
- means for biasing said plate in a first direction along the first reciprocating path;
- and
- means for securing said plate in a predetermined position along the first reciprocating path;
- a sheet support mounted at each of the left side and right side adjacent the bottom end of said frame, each of said sheet supports including:
- a member having a sheet supporting surface lying in a plane generally normal to the sheet receiving surface, said member of each of said sheet supports includes;
- a first arm having said sheet receiving surface;
- and
- a second arm normal to the first arm;
- and;
- means for mounting said member to said frame for movement along a second reciprocating path between the right and left sides of the frame;
- said mounting means of each of said sheet supports includes;
- at least one guiderail mounted to said frame with the longitudinal axis generally parallel to the bottom end;
- said second arm having at least one groove for receiving said at least one guiderail;
- means for securing said member of said sheet support in one of a number of preselected positions along the second reciprocating path between the right and left sides of said frame, said securing means includes a pin for locking said second arm on said at least one guiderail at a selected location.
