THOMAS OVERGAARD, OF SYDNEY, NEW SOUTH \VALES.

JOINT FOR BOX -EDGES.

SPECIFICATION forming part of Letters Patent No. 436,149, dated September 9, 1890.

Application filed January 10, 1890. Serial No. 336,529. (No model.) Patented in New South Wales October 16,1889, No. 1,770.

To all whom it may concern:

Be it known that I, THOMAS OVERGAARD, agent and importer, a subject of the King of Sweden and Norway, residing at No. 1 Change Alley, in the city of Sydney and British 001- ony of New South Wales, have invented new and useful Improvements in Means for J oining "the Contiguous or Adjacent Edges of Boxes, (for which I have obtained Letters Patent in New South Wales, dated October 16, 1889, No. 1,770,) of which the following is a specification.

This invention has been devised in order to produce a strong, convenient, and cheap case or box in which may be packed and transported all kinds of chattels, merchandise, and especially bulk goods. This packing case or box is so constructed that it may be easily taken apart for transmission as an empty and will then occupy but little space.

To these ends the invention consists, essentially, in the means for joining the contiguous or adjacent edges of the box by binding or uniting the same, or some of them, with ape culiarly notched or slotted material, so that when said sides and ends are placed together the notched or slotted binding material, over the edges forms straps and alternating knuckles of hinges at the corners, through which hinges spiral rods or pins are twisted or inserted and firmly fasten the sides and ends of the case or box into one whole. The sides and ends with the binding hinge-forming material thereon might be used to construct cases or boxes of any convenient shape, although I prefer to construct cases of parallelopiped form, in which case it is only necessary to have the binding material or hinge at eight of the twelve corners or angles. I also prefer that this binding hinge-forming material should be strong enough to connect together two or more pieces to form one end or side.

In order that this invention may be clearly understood, reference will now be made to the drawings herewith, in which- Figure 1 is a perspective View of a packin g case or box constructed according to this invention, while on a larger scale Figs. 2, 3, and 3 show, respectively, part elevation and sections of one of the'corners or angles of the same. Fig. 4 shows binding material flattened out.

A A are the sides and ends, and B the binding material thereon. a

C are spiral fastening-pins.

B are angular notches or slots, 13 the angular knuckle-forming part, and B nails or rivets. It is preferred that the angles with the corner or hinge at which the notches or slots B are out should be the same as the angle or pitch of the spiral G.

In Fig; 3 the binding material is shown with two wings or flaps to take round the edge of the side or end to which it is attached, while in Fig. 3 it has but one, which is fast ened to the outer edge of the side or end of the box. 1

In constructing a packing case or box such as that shown, its size having been previously determined, I take the pieces of board or other material which are to be joined to form a side or end, and'around the edges I nail or rivet the binding hinge-forming material. This hinge-forming material is supplied in the form of strips of metal-say galvanized or plain iron, tin, zinc, copper, brass, &c.-

from the center of which two contiguous diamonds or angularly-set parallelograms have been notched or slotted, cut, or stamped at regular distances apart, each said distance being preferably .just slightly shorter than the length of the notched or slotted part. The sides and ends having been thus bound on their edges and placed together, the alternating and interengaged angular knuckles B of the binding materials are formed into a hinge or a fixed corner by inserting the fastening-spiral G, which spiral is inserted by being twisted or revolved and finds its way through and draws them together, making a female screw or helix of them. These fastening-spirals, being made of metal or such like material, have suflicient spring to allow them to be easily threaded through the knuckles, and they are retained in place after threading by the spiral or helical bed. The ends might be turned slightly over or carry a nut or key to form a convenient revolving handle; but they are preferably turnedor revolved by pliers or pinchers. It will be seen that at four of the twelve angles there is no binding or fastening; but, if required, these angles or corners may be fastened similarly to the others. Any one side or end of the case or box may then be used as the cover, one of its bound edges and the contiguous edge of the next side or end forming its hinge, and the fastening-spiral parallel to the spiral of said hinge being Withdrawn allows the cover to open. The box may be easily taken to pieces for transshipment as empty by withdrawing the fastening-spirals by revolving them, say, by grasping their ends with a pair of pinchers or pliers.

It is to be understood that I do not confine myself to any precise form or size of which my improved packing case or box may be con structed, nor to any precise material or size or strength of any of its parts, so long as the nature of my invention be retained.

Having now particularly described and ex-- plained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A joint for joining contiguous edges of a box, consisting of hooks, loops, or eyes connected to said edges so as to incline toward each other and a spiral Wire extending there through, substantially as set forth.

2. A joint for joining contiguous edges of a box, consisting of hooks, loops, or eyes connected to said edges so as to form portions of spiral threads and a locking-wire extending through said hooks, loops, or eyes, substantially as set forth.

3. A joint for joining contiguous edges of abox, consisting of hooks, loops, or eyes connected to said edges so astoform portions of spiral threads trending in opposite directions and a locking-wire extending through said hooks, loops, or eyes, substantially as set forth.

at. A joint for joining contiguous edges of a box, consisting of hooks, loops, or eyes connected to said edges so as to form portions of spiral threads and a spiral locking-wire extending through said loops, hooks, or eyes, substantially as set forth.

5. A joint for joining contiguous edges of a box, consisting of hooks, loops, or eyes connected to said edges so as to form portions of spiral threads trendingin opposite directions and a spiral locking-Wire extending through said loops, hooks, or eyes, substantially as set forth.

6. A joint for joining contiguous edges of a box, consisting of strips of metal having formed therein slots at an angle to the edges of the strips and bent or doubled centrally along the slots to form loops or eyes, said strips being secured to said contiguous edges so that the loops will overlap and form portions of spiral threads trending in opposite directions, and a locking Wire extending through said loops, substantially as set forth. 7.
