LYMAN MILLER, OF LEXINGTON, KENTUCKY.

BOX-TOP.

SPECIFICATION forming part of Letters Patent No. 525,917, dated September 11, 1894.

Application filed May 16, 1894- To all whom it may concern:

Be it known that I, LYMAN MILLER, of Lexington, in the county of Fayette and State of Kentucky, have invented a new and Improved Box or Case Top, of which the following is a full, clear, and exact description.

My invention relates to improvements in that class of tops which are applied to show cases, packing boxes and similar things; and the object of my invention is to produce a top or side, which may be conveniently applied to ordinary dry goods boxes or cases, so that they may be piled safely one upon the other and yet have the goods in them capable of easy and advantageous exhibition, which comprises a pair of swinging doors connected in such a way that a tight joint is formed between them, which has the doors closed automatically by a spring attachment, which has means for holding the door,which is permitted to swing, open, and which is cheap enough to enable it to be applied to almost any box or case.

To these ends my invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings forminga part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a perspective View of a case provided withemy improved top. Fig. 2 is a broken enlarged front elevation of a portion of the top, showing the hinge connection between the two parts thereof. Fig. 3 is a broken end view of the top. Fig. 4 is a cross section on the line 4: 4: of Fig. 2. Fig. 5 is a cross section on the line 5-5 of Fig. 2. Fig. 6 is a broken-plan View of a slightly modified Fig. 7 is a similar view of another modification of the invention. Fig. 8 is a cross section on the line 8-8 of Fig. 6; and Fig. 9 is a cross section on the line 9-9 of Fig. 7.

The improved top embodying my invention may be used on either the top or side of a box and is, as a matter of fact, generally used on the side. It comprises two similar parts or doors 10 and 11, which, as illustrated,form the front side of a box or case 12 which may Serial No. 511.439. (No model.)

I be of any usual form, and the lower part or door 11 is fastened in place by thumb screws but may be fastened in any convenient way, while the upper door 10 is permitted to swing outward and downward but is normally closed by the springs described below. If desired the upper door may be fastened rigidly and the lower one permitted to swing.

The door has its inner rail convex, as shown at 13 in Fig. 5, so as to fit snugly with the concave portion 14 of the inner rail of the door 10, but at the ends the inner edges of both rails are recessed, as shown at 15,'in Fig. 4, to receive the spiral springs 16, see Figs. 1 and 2, which are coiled between the two rails and have their ends fastened to opposite rails, as shown at 18 in Fig. 4, and thus the tension of the springs is such that if either door is opened it will be automatically closed and will also be held tight when closed.

The two doors are connected by hinges 17 and, under ordinary circumstances, one door is fastened to the box or case, as specified, and the other used to gain access thereto. On the door 10, at the ends, are pivoted legs or arms 19 which have their free ends bent inwardly, as shown at 20, these being adapted to lie in grooves in the door, as shown by dotted lines in Fig. 1, so as topermit the door to close snugly, but when the door is open, the inwardly bent ends 20" rest on the edge of the case and the legs thus serve to hold the door open against the tension of its spring.

It will be readily seen that the improved top or side described above may be conveniently applied to a series of cases, so that the latter may be piled one upon another and the goods in them may be seen through the glass in the doors, while the door 10 may be swung open to permit the goods to be removed and, as above remarked, the door 11 may be also made to swing if desired.

In Figs. 6 and 8 I have shown a slightly modified form of the invention, in which one meeting rail is convex and the other concave as already described, and as shown in Fig. 8, the convex portion is longitudinally slotted, as at 21, to receive the spring rod 22 which extends longitudinally through the slot and has outwardly bent ends 23, see Fig. 6, which extend in opposite directions, one being se- ICO cured to the door and the other to the door 11, so that the spring rod acts as above described to hold the doors tightly closed.

As shown in Figs. 7 and 9, the inner ends of the meeting rails are both concaved and between them is held a tube 24 extending from hinge to hinge, and the spring rod 22 extends through this tube and its bent ends 23 project outwardthrough slots 25 in the tube and are fastened to the doors, as above described.

Having thus described my invention, I olaimas new and desire to secure by Letters Patent- 1. A top or front for cases comprising two rectangular frames placed edge to edge and each formed of connected top, bottom and end rails, and an interlocking concave-convex joint being formed between said meeting edges and the edges of these concave and convex portions being cutaway at one side to permit one door to swing outwardly'at right angles, the hinges connecting the ends of said meeting edges and lying within the plane of the doors to avoid projecting parts, and a spring between the said meeting edges to hold the doors closed, substantially as described.

2. A top or front for cases comprising two rectangular frames formed of connected top,

bottom and end rails, and provided on their abutting edges respectively with a concave groove and a longitudinally recessed convex rib fitting therein, a spring rod entending through said rib recess and having its oppositely bent ends engaging the respective frames, the edges of the two frames at one side of the groove and rib being cut away to permit either frame to swing outwardly, and hinges connecting the two frames and lying in the plane thereof, substantially as described.

3. The combination with the two door frames hinged together at and having their abutting edges formed with an interlocking concavo-convex joint, said edges being cut away at one side of the joint to permiteither door to swing outwardly, of astop leg pivoted to one end of the swinging frame and having its free end bent inwardly across the inner face of said frame to engage the edge of the box to which said door frames are applied, a recess being provided to receive said bent end to permit the complete closure of said frame, substantially as described.

LYMAN MILLER.
