SAFE CORNER CONSTRUCTION.

Application filed January '7, 1924. Serial No. 684,729.

To all whom it may concern:

Be it known that I, CHARLES J. Barns, J12, a citizen of the United States, residing at Englewood, county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Safe Corner Constructions, of which the following is a specification.

This invention relates to safe construction, and more particularly relates to the corner construction of safes incorporating angle irons bounding the edges of the safe.

Heretofore it has been customary to miter the bounding angle irons of safes, safe cabinets or the like at the corners of the safe and to weld the meeting edges together from the outside, and then to trim off the seam on the outside by a grinding process. To reduce the number of such seams in a safe the bounding angle irons sometimes have been bent around one or more of the corners. The mitering and bending must be accurately done, requiring great care and considerable time.

The principal object of my invention is to provide an improved method of constructing the corners of safes, safe cabinets, or the like, having metallic edge members, whereby with less time and care a stronger construction may be had. Another object of my invention is to provide a method of constructing the corners of a safe, safe cabinet or the like having metallic edge members, without requiring the edge members to be accurately mitered or cut, permitting the use of separate lengths of angles, and permitting the corner joint to be established by welding from the inside, and thereby securing a neat joint or seam without requiring trimming off or grinding. A further object of my invention is to provide a safe corner construction which is extremely strong, and at the same time is simple and may be easily and inexpensively produced. Other objects of my invention will be in part obvious and in part pointed out hereinafter.

In accordance with this invention, a separate piece is provided, shaped to it over a corner of a safe, safe cabinet or the like. Such corner piece may be designed to overlap the ends of the edge frame members which approach the corner, permitting the ends of the framing members to be welded square as desired.

to the corner piece by spot welding or by welding only from the inside of the construction, and in either case the ends of the frame members may be mitered or cut off In this way the corner incorporates the additional reenforcement of the overlaid corner piece and at the same time may be easily and quickly built up, avoiding the necessity of accurately cutting and fitting together the ends of the frame members, and, when the welding is accomplished along the seams entirely on the in side of the construction, the necessity of trimming or grinding on the outside to obtain neatness and a finished appearance is eliminated. If desired, however, the corner piece may be so designed that the angle irons, cut off square, will abut the edges of the corner piece and may be secured thereto by butt. welding, instead of accomplishing the weld by hand. By using the separate corner piece a neat uniformity of rounding is obtained which is practically impossible when the angle iron is rolled around a corner. I s

In order that a clearer understanding of my invention may be had, attention is hereby directed to the accompanying drawings forming a part of this application and illustrating certain possible embodiments of my invention. Referring to the drawings, Fig. l is a perspective View of a corner fragment of a safe looking from the outside of the construction; Fig. 2 is a perspective view of the same looking from the inside of the construction; Fig. 3 is a sectional view of one of the seams or joints, and is taken on the line 38 of Fig. 2; Fig. 4 is a perspective view of a corner fragment of a safe having a slightly modified embodiment of my invention, the View showing the exterior of the construction; Fig. 5 is a perspective view of the same looking from the interior of the construction; Fig. 6 is similar to Fig. 5 but shows spot welding between the angle irons and corner piece; Fig. 7 is an exterior perspective view of a corner fragment of a safe showing a modified form of construc tion; and Fig. 8 is a sectional View thereof and is taken on the line 88 of Fig. 7 Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring to the drawings, the corner construction illustrated in Figs. 1, 2 and 3 comprises usual body walls 1 and edge frame members .2 Which are angular in cross section and are secured along their side edges to the edges of the body Walls 1. Instead of bending one of the members 2 about the corner or welding the ends ofthese members together at the corner from the outside, I provide a separate corner piece 3, shaped to fit over the corner and to overlie the ends of the frame members 2. I then weld the ends of the framing members 2 to the inner surface of the corner piece 3from the inside of the construction, as at at, thus not only effecting a secure joining of the frame members 2 at the corner with the additional reenforcement of the separate corner piece at the corner, but also securing a neat and even rounding atthe corner. It being possible to perform all the welding on the inside of the structure, as at 4, it is not necessary to have any welding on the outside, and, therefore, a neat corner may be constructed without entailing trimming or grinding on the outside.

The shape of the frame members 2, ob viously, may be varied considerably and still be susceptible to joining by means of a suitable corner piece. Moreover, the ends of the frame members 2 may be mite-red or not, as desired. In Fig. 2 the frame members 2 are shown mitered for adistance, as at 5, and then are cut off square, as at 5.

The frame members 2 illustrated have along their edges outwardly directed channels 6 in which the edges of the wall plates 1 are seated. The inner walls 7 of the channels are extended and abut the. inner surface of walls 1, to which they are welded, as at 8.

This type of frame member is found to be extremely desirable and is disclosed inan application filed by Carl Bartels and David H. Bellamore on July 7, 1921, Serial No. 482,893, Patent No. 1,485,360, issued March 4, 1924.

In the modifications shown in Figs. 5 and 6, only the inner flange portion 7 of the frame members 2 are shown mitered, as at 9, the remainder of the frame members being cut off square, as at 10. In these embodiments the separate corner pie e 3 is extended somewhat along the frame members 2 so as to sufficiently overlap the ends 10 of the frame members to permit adequate welding of. the ends of the frame members 2 to the corner piece 3, either by welding from the inside, as at 4, in Fig. 5, orby spot Welding, as at 4L, as in Fig. 6.

Obviously, if desired, the frame members 2 may be mitered all the way to the corner. When the frame members are mitered, however, they are preferably so formed that they will not form a tight fit and will allow suflicient space for proper welding to the corner piece.

In forming a corner construction in accordance with the above, the frame members may be cut to length, fitted in, the corner piece applied, and the parts welded up in very much less time and with considerable less labor than would be required to accurately miter the f 'ame members, weld them together from'the outside, and then trim off by a grinding process on. the outside. vThis is especially true with. frame members such as are illustrated in the drawings, since it is ditlicult to miter and weld together such frame members accurately due to the channel formation along their edges.

Another possible modification is illustrated in Figs. 7 and 8. In this embodiment the ends of the angle iron frame members 11 are cut off square and directly abut the edges of a corner piece 12 so that they may be secured to tho cornerpiece by butt welding, as at 13. s

As many changes could be made in the above constructions and as many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

IVhat I claim is 1. In safe construction, in combination, frame members having outwardly presented grooves along theiredges, body plates seated in said grooves, and a separate corner piece welded to; the ends of said frame members at a corner of the safe.

2. A plurality of frame members having ends meeting at a corner of the safe and having outwardly presented grooves along thelr edges, body plates seated in said lapping the body portions of said frame members and welded thereto, portions of the said ends of the frame. members meeting each other in a mitre joint.

3. A plurality of frame members having ends meeting at a corner of the safe and having outwardly presented grooves along their edges, body plates seated in said grooves, and a separate corner plate overlapping the body portions of said frame members and welded thereto, portions of the said ends of the frame members meeting each other in a-mitre joint and other portions of said frame member ends being cut off square.
