HENRY A. HOUSE, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO THE COMPRESSED PAPER BOX COMPANY, OF SAME PLACE.

PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 327,555, dated October 6, 1885.

Application filed December 8, 1883.

To @ZZ whom it may concern:

Beit known that I, HENRY A. HoUsE, of Bridgeport, Fairfield county, State of Connecticut, have invented certain Improvements in the Manufacture of Paper Boxes, of which the following is a specification.

My invention relates to that class of paper boxes in which the body portion consists of a cupvshaped section inclosing a cylindrical section upon which the cap is supported, and my invention consists in a box having` the outer section formed with an open or hollow bead near the lower end; and an inner section made of one continuous piece of material drawn to a cylindrical form tapering in crosssection inserted within and secured to the outer section to constitute a guide for the cover ofthe box, all as fully set fort-h hereinafter.

In the drawings, Figure l isa section of the outer body portion of the box as drawn up prior to forming the bead. Fig. 2 is a section showing the mode ot` forming the bead. Fig. 3 is the complete box-bodyin section, and Eig. 4 is a section of the completed inner cylinder.

The body of the box is made from two sheets or sections of paper, one being drawn up by dies to form the cup shaped body A, as fully set forth in Patent no. 209,686, granted to me November 5, 1878, the other section being formed into a hollow cylinder, B, open at both ends.

As a cup-shaped piece of the form shown in Fig. l would not retain its shape unless made ot' extremely heavy material, I avoid the expense of using such material by forming a hollow beador iiange, a, at and surrounding the bottom of the cup, as shown in Fig. 3. I form this bead by means ot' dies C D, adapted to receive the cup between them, and forming by their shapes an annular groove conY forming to the shape of the intended bead, and an expanding-tool, E, which has an external annular rib, e, which, when the tool is introduced into the box and expanded, forces out a portion of the material near the bottom of the box and into the groove formed by the dies.

The box is preferably in a dampened condition when these operations are performed, and when afterward dried will retain the form thus imparted, the rib a stifteniug and Serial No. 113,908. (No model.)

strengthening the same, and affording also an ornamental finish.

Io secure greater stiffness, I subject the bead to pressure by bringing the upper die, D, with considerable force downward, thereby condensing the material between the two dies and upon the rib e, and making it hard and rigid. The cylinder B is now inserted in the cup portion, and, if desired, cemented thereto, forming the body, as shown in Eig. 3, and a cup formed in the same manner as the ribbed cup A may be applied as a cover.

It will be seen that when the cylinder B is inserted in its place it crosses the open side of the bead a, and forms therewith a hollow girder, adding materially to the rigidity of the structure.

The cylinder B is pressed or drawn from a single piece in the manner shown in my aforesaid patent-that is, a cup is formed and the bottom portion then cutout, and thus formed it is less likely to fold in or lose its shape than those made by bending strips into rings. The pressure condenses and hardens it, rendering it more elastic, and the drawing action ot' the dies imparts a slight taper, making it thinner at the upper edge, so as to facilitate the application ofthe cap.

By thisconstruction I am enabled to secure all the stiffness, rigidity, and durability required, while using extremely thin and cheap material.

It will be apparent that the drawn and tapered cylinder B may be applied in boxbodies made in the ordinary manner, and that the ordinarybent strips maybe used in beaded cup-sections formed as described.

I claim- I. A box-body consisting of a cup-shaped section having a hollow bead, a, near the lower end, and a cylindrical section, B, confined within the Harige of the outer section, substantially as set forth.

2. The annular inner section ot' a box-body, consisting of one piece of material drawn to a tapering form in cross-section, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

Vitnesses: HENRY A. HOUSE.
