SPECIFICATION forming part of Letters Patent No. 405,562, dated June 18, 1889,

Application filed August 13, 1888. $erial No. 282,487. (No model.)

To (all whom it 71mg concern:

Be it known that l, PHINEAS F. KING, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Burglar-Proof Safes, of which the following is a specification.

My invention is an improved means of constructing burglar-proof work, such as safes, vaults, and other secure receptacles for storing and protecting valuables.

It consists, primarily, in means for constructing the skeleton of the structure and so forming the interlocking joints that the parts are entirely secured togetherfrom the inside, and the possibility of stripping the plates or wedging the joints apart is precluded.

It also consists in certain features of construction calculated to reduce the labor of fitting and add to the strength of the structure, all of which will be first fully described in connection with the accompanying drawings, and will then be particularly referred to, and pointed out in the claims.

Referring 110w to the drawings, in which like parts are indicated by similar reference-letters wherever they occur throughout the various views, Figure 1 is a horizontal section of a vault constructed according to my invention. Fig. 2 is a detail sectional view of the interlocking edges of the wall-plates separated. Fig. 3 is a similar view of the plates secured together by an interior lap-plate. Fig. at is a similar View of the lock-joint, but with the locking-tonguc formed inward from the edge, and the groove and rabbet upon the edge of the opposite plate formed to match and admit of tightening-screws being used upon each side of the tongue. Fig. 5 is a transverse horizontal section of the skeleton before the plates forming the walls are secured in place. Fig. 6 is a perspective view of one corner of the angle-bar frame which forms the front and rear frames of the skeleton, and one end of one of the angle-bars which connect two angle-bar frames to form the skeleton of the safe or vault, the frame and connecting -bar being disconnected to clearly indicate the details of construction of each. Fig. 7 is a plan view of a part of one of the angle-bars grooved and notched preparatory to bending at the notched portions to form the angle-frame, one corner of which is shown in Fig. 6. Fig. 8 is detail perspective view of one corner of one of the plates which form the walls of the safe.

The skeleton of the vault is formed of two frames A, formed of bent angle-bars, and four straight angle-bars B, which connect the two frames at their corners. The angle-bars and angle-bar frames are preferably of laminated steel and iron.

To form the frames A, angle-bars of the proper length to make frames of the desired size when bent are first planed off upon their inner edges, forming rabbets a, and are then grooved at a, after which one web is notched at a at the four points at which the bar is to be bent to form the rectangular frame. The straight an gle-bars are similarly rabbeted and grooved upon the inside edges. Each end of the bars 13 is transversely grooved at Z), forming the reduced angular tongue Z), to fit into the groove to, the groove 1) fitting the rabbets a upon the inside of the angle-frame A. The ends of the bars thus match with the corners of the angle-bar frame and make a smooth finish inside and outside.

The angle-bars B are firmly secured to the angle-bar frames by steel screws passing through the holes b in bars B into the screwtapped holes a in the angle-bar frames.

After the frame or skeleton of the safe or vault is formed by uniting two frames A by four angle-bars B the wall-plates C, Fig. 8,

which have their edges grooved at c and formed into tongues c to match into the grooved and rabbeted edges of the angleframes and bars, are inserted in place from the inside and secured in place by steel bolts D.

If the vault or strong box is of such size as to require more than one plate, the meeting edges of the plates are matched together in the mannershown that is, the meeting edges of the plates are grooved and rabbeted upon the opposite faces, so that the outer and inner faces of the walls present smooth even surfaces. The plates are secured together and to the angle-frames by steel screws pass ing through the thinn er bottoms of the grooves into the tongues, as seen in Fig.1; or where the inner steel lap-plates are used, as seen in Fig. 3, the screws may be passed through the inner steel plate into any part of the outer plates. The jamb-plates or stiles for the door are secured to the front frame the same as the plates.

It is evident that the walls of my vault or strong box may be made of any desired thickness by using more or less plates upon the inside, and it .is also evident that the grooves and rabbets may be reversedthat is, formed upon the opposite sides of the angle frames, bars, and wall-plates from those shown in the drawings. I11 fact, I find it best in constructing large vaults according to my invention to employ the angle-bar frames at top and bottom of the structure, and employ the straight angle-bars for the upright corners. In this case I also prefer to rabbet and groove the lower or horizontal web of the lower frame upon the outside, so that the inner plates may be more readily introduced and secured, after which the bottom of the vault is secured in place and the caster-frames, when such areused, are secured from the inside, thus overlapping the joints and giving additional strength to the lower corners.

The meeting ends of the angle-bar frames understood, of course, that after the parts are properly dressed and fitted together, the screwholes bored and tapped, the parts are again straight angle-bars B, similarly grooved upon their inside faces, and transversely rabbeted and grooved at b b to match into the corners of frames A to form the skeleton of a burglarproof safe, substantially as hereinbefore set fortlr- 2. In a burglar-proof safe, the combination, substantially as specified, of the angle-bar frames tongued and grooved near their edges, as shown, the straight angle-bar pieces similarly tongued and grooved, and also tongued and grooved transversely at each end to match the corners of the frames, and the wall-plates for the body of the safe having their, edges formed to interlock with the angle-bar frames and their connecting angle-bars, for the purpose set forth.

The eombination, in a burglar-proof safe, of the angle-bar frames, the straight anglebars connecting twoof said frames, and the wall-plates C and interior lap-plates, said frames, angle-bars, and plates 0 having overlapping and interlocking edges, whereby the parts may be secured together from the inside and wedging or separation of the parts prevented.
