SPECIFICATION forming part of Letters Patent No. 289,790, dated December 4, 1883. Application filed September 26, 1883. (No model.)

To all whom, t may concern.-

Be it known that I, MYRON L. VrLcox, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in the Construction of Paper Box'es 5 and I do hereby declare that the following is a full and exact description thereof.

-My improved boxes belong to the class known in the trade as locked boxes, being made of stiff paper-3X or 4X manila or other suitable material-eut by machinery, and with the proper creases and corners initiated by machinery, but with the flaps finally engaged together without paste or other cement by simply locking togetherthe iiaps by means of properly-formed tucks. The firm of J. WV. lVilcox Si Sons, of this city, and other boxmanufacturers, have long used a simple tuck analogous to a pocket-book tuck; also, a mode of locking in which side 'extensions or wings projecting from a narrow iiap are received in holes in an opposite broad flap. The present invention combines both these principles. I produce a narrow hap having side wings,

the flap in opposite directions, beingl inserted through a hole in the opposite iiap, and also extend the narrow ilap, so that not only its side wings, but also its end, is inserted through the hole in the flap. It is for some uses important to be able to conveniently unlock the box without tearing or straining the tuck. I provide a handle, properly located, for this purpose by simply producing a semicircular slit in the material at the right point. The semicircle thus described may be bent Vup or may be cut out and removed altogether. In the first case it serves as a handle to be grasped. In the latter case it serves as a handle in which thethumb or finger is inserted. The sides as well as the ends may be similarly locked. I will show the invention as mainly applied to the ends.

The accompanying drawings form a part of this specification, and represent what I con sider the best means of carrying out the invention.

Figure l is a perspective view of an end of the completed box, with the flaps locked together ready for use. Fig. 2 is on a smaller scale. It shows the stout paper for the entire box in an extended condition'. Fig. 3 is an end view of the completed box. Figs. 2 and 2" show the sides equipped for being similarly 55 joined. Figs. 3 and 8 show a modification, in which, instead of the rectangle being eut out entirely, it is only cut on three sides, and4 the inelosed material deiiected down instead of being removed altogether. Fig. 3n shows 6o the aperture thus made, and Fig. 3b shows the lock completed. Fig.` 4 shows the tuck with a semicircular hole instead `of a semieireular l flap for a handle.

Similar letters of reference indicate corre- 765 sponding parts in all the figures.

The entire box is formedfroin a single piece of sui'liciently stout paper or other material capable of being folded. The four sides A of the main body are formed as usual. The joint 7o may be re-enforced by lapping the edges over la considerableportion of one side. These parts may overlap or not. This depends on the width and thickness of the box.

I have shown two end ilaps folding inward from the sides marked A. The novelty lies entirely in the front and rear fiaps. The rear ilap is marked B. A considerable rectangular hole is produced by suitable dies near the middle of this lap,as indicated by b. 8o A portion of the front fiap where it attaches to the main body is of the usual width. Beyond this is a narrowed portion, which I will term a tuck. 7 It is marked D, certain portions being designated,when necessary, by addition- 8 5 al marks, as D2 D3. rIhe neck or point of junction of this tuck D with the part D is narrower than the hole b in the opposite ilap. Beyond this the tuck is widened by wings DZ D2.

The length of the tuck D is greater than the 9o u corresponding dimensions of the hole b.

To lock the parts, the ilaps A' having been previously folded down, the rear flap, B, is brought lightly down nearly to its nal position; then the finger and thumb being applied 9 5 to the wings D'z to bend them downward toward the hole b, the entire hap D, and its tuck D', and partially-folded wings D2 are folded over upon the ap B, so that the end D3 of the tuck D is thrust downward through the hole 10o b after the wings DZ are -thrust downward through the said hole; then the wings D2 are liberated and allowed. to expand, the entire front ap, as also the entire rear flap, are iiattened down by hand or otherwise, and the lock is complete. A semicircular cut, d, having been previously made in the material in the position indicated, the lip, thus partially liberated, can be bent upward, when required, and serve as a handle by which to withdrawthe tuck. By grasping this lip with the thumb and finger and pulling, the force will be exerted on the central portion of the tuck D', and induce a curving of' the material thereof, which will allow the wings D2 to assume the same form which they did when they were introduced, and permit the tuck to be readily withdrawn by areverse movement. In the most complete means of carrying out the invention, both ends of the box are formed in the manner here described, and the entire box may be knocked down7 after being folded around, so as to form the sides A completely, but leaving the ends open. I d0 not confine myself to that construction.

Modifications may be made in the forms and proportions. The wings D2 may be made of rectangular outline instead of round. The end of' the tuck D' may be square or rounded instead ofpointed, as shown. In large boxes I can make two or more of the narrow flaps D',

' each with their wings D2,and correspondingly provide an opposite ilap, B,with two holes, b. I can make the side flaps.A',longer or shorter, or can dispense with them altogether. Iprefer to equip both ends of the box with the narrow tuck D', with its wings D2; but this is not essential. One end may be secured by any other means. For some uses the opposite end may be left entirely open. The material set free by the semicircular cut d may be deflected by receiving the end of the finger.

upward to serve as a handle to be grasped, or may be cut out altogether, allowing the aperture thus formed to serve as a holding means The term cut Wis used to designate both forms of' the handle.

' The invention may be applied to the manufacture of boxes of widely-varied dimensions and proportions. I propose to employ it in pocket-books.

I claim as my inventionl. In a folded box, the flap B, having the aperture b, and the winged tuck D' D,.of a greater length than width, combined with convenient means for lifting the tuck D' at its center, and all arranged as shown, so thatr in locking the parts not only the side Wings, D2, but also the end D3 of the tuck D' is engaged in the hole b, and all the wings may be readily disengaged, as herein specified.

2. In a folded box having a tuck, D', provided With wings D2, engaged in the shorter and narrower hole b in the opposite iiap, B, substantially as specified, a handle formed by the cut d, arranged as shown, so that on applying force thereto to open the lock the tuck D will be lifted by its center and the wings D2 deiiected downward7 substantially as herein specified.

'In testimony whereof I have hereunto set my hand, at Rochester, New York, this 13th day of September, 1883, in the presence of two subscribing witnesses.
