ABSTRACT:
A portable folding table system especially adapted for support on a bed, which folds for storage and which when open provides aligning, work supporting and work ventilating facilities; a grid on the table surface supplies means for squaring the weave of cloths being worked on the table, rods on opposed edges of the table parallel with lines of the grid provide guides for a snap-on graduated straight edge slidable on the rods to align patterns placed on the cloth being worked with the weave of the cloth; folding clips with sized holes cramp the rods in the holes to constrain the rods in working position; sliding-bolts maintain the table panels in-plane and detachable legs with large-area feet provide secure, damage-free support on a bed or the like when the table is in use; when folded the table provides capacious, internal storage for the rods, legs, straight edge and other accessories and materials used in sewing; a system of surface perforations coincident with intersections of the grid permits ready drying of cloth articles spread out flat and a tactile indication useful in sewing operations of the location of grid intersections when concealed by cloth.
