UNITED" STATES PATENT OFFICE.
LUTHER C. CROWELL, OF BOSTON, ASSIGNOR OF ONE-FOURTH HIS RIGHT TO LUTHER CRANE, OF CAMBRIDGE, AND ONE-FOURTH OF HIS RIGHT TO GALEN COFFIN, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN PAPER-BAGS.
Specification forming part of Letters Patent No. 123,811, dated February 20, 1872.
To allpwhom it may concern:
Beit known that I, LUTHER C. GRoWELL, of Boston, in the county of Suiollr and State of Massachusetts, have invented a new and Improved Mode of Constructing Paper.'-Bags; and I do hereby declare that the following is a full,.clear, and exact description of the same, and taken in connection with the drawing which accompanies and forms a part of this specificationis sufficient to enable those skilled in the art to make and use the same.
My invention relates to the manufacture of square-bottomed bags; and consists in so folding and cementing a strip of paper that when cut into sections of suitable length, one end being closed by one fold, the bottom of the bag or case thus formed when opened or filled will assume aV quadrangular shape.
I will now proceed to describe my invention, reference being had to the accompanying drawing on which similar letters of reference in the di'ierent views indicate corresponding parts.
I consider it preferable to make a tube of paper by lapping and cementing the edges together, said tube to be made from continuous bands of paper and wound upon suitable rolls or mandrels. When said cemented edge 01 joint is sufficiently dry I then, by any suitable machinery, make a longitudinal lap or fold on each side of the tube, bending the same into the tube, as shown at Fig. l, a, a representin longitudinal folds. The tube thus folded should now be cut through the upper or lower plane, said out extending laterally from the edge b to the edge c. v The remaining portion of the tube is now severed, so as to leave the lip or end d projecting beyond the edges of the tube, as The lip or end d should now be covered with cement, and with a portion of .the outside or lower surface of the same.- A
crease, c, made across the bag or case, as shown at Fig. 3, at-such distance from the closed end as will correspond with the depth of the longitudin a1 folds, would determine the form which it is desired lthe bag or case should assume when filled, or the same result would be obtained by turning the corners s into the longitudinal folds, as represented by dotted lines lv fv.
I am aware that paper-bags have been made which will assume a quadrangular shape when filled; but claim the method herein described as the most simple and practical, as by this process and the proper machinery, bags which will assume a quadrangular shape can be made as economically and as rapidly as the common bags.
vI claim- As a new article of manufacture apaper bag, having two longitudinal inward folds, a a, terminating with a single lateral fold extending from b to c, and cemented to its body, forming the bottom, as herein shown, and for the purpose set forth.
