SAFE on VAULT WALL.

Specification of Letters mam.

Patented Aug. 18., 1922.

Application flle'd November '15, 1918. Serial No. 262,636.

vwalls for safes or vaults which are constructed of manganese steel or other metal which cannot be machined and which are formed in separate wall plates or sections arranged edge to edge andsecured together.

The .object of .my invention is to provide a wall structure of novel, simple and efficient construction, wherein the wall plates thereof are secured together by a novel means which will efiectually prevent both lateral and edgewise displacement of the wall plates relatively to each other, and which will permit the parts to be assembled in a manner to draw the opposing edges of the plates together and retain them in close contact with each other.

With the above and related objects in view, my invention consists in the novel construction and combinations of parts hereinafter fully described and particularly claimed.

In the accompanying drawings, illustrating my invention,

Figure 1 is a perspective view of a part of the meeting portions of two wall plates for a safe or vault, made in accordance with my invention, showing the studs thereon before they are riveted in the connecting plates.

igure 2 is a similar view, including a series of connecting plates and showing the studs riveted in holes in the connecting plates.

Figure 3 is a view similar to Fig. 2, showing a continuous connecting plate instead of a series of connecting plates.

Figure 4 is a section, on line 44 of Fig. 2, showing the positions of the assembled parts before the studs are riveted in the holes in the connecting plate.

Figure 5 is a view similar to Fig. 4, after the riveting operation.

Referring to the drawings, 2 and 3 designate two adjacent wall plates, and 5 and 6 connecting plates for the

wall plates

2 and 3.

The

plates

2 and 3 are adapted to form parts of the top, bottom or side walls of a safe or vault. The adjacent-edge portions of the

plates

2 and 3 abut against each other,

and the edge portion of the plate '2 is provided with a central, longitudinally-extending rib 7 which is fitted zinto a central, longi tudinally-extending groove 8 in the adjacent edge portion of the plate 3. The plates 2 and '3 are usually formed of unmachinable metal, such as manganesesteel, and theedge portions thereof are finished to fit against each other by "suitable grinding operations,

well known to persons skilled in this'art.

The-wall plates 2 and 3'are provided with pro eating pins or studs-9 {and 10, respec- =t1ve y, arranged at intervals along the meetang edge portions of t1 plates. These

studs

9 and 10 are formed or cast integral with the

plates

2 and 3, and the

studs

9 and 10 project from the inner faces of the

plates

2 and 3.

Arranged against the inner faces of the

wall plates

2 and 3 are a number of suitably spaced connecting plates 5, as shown in Figs. 2, 4 and 5, which cross the joint between the

plates

2 and 3, and which may be formed of any suitable material, preferably machinable metal. The studs 9 of the plate 2 are paired with the studs'lO of the plate 3, and a connecting plate 5 is provided for each pair of studs. The connecting plates 5 are provided with

counter-sunk holes

11 and 12 into which the

studs

9 and 10 extend, as clearly shown in Fig. 4.

In. assembling the parts, the rib 7 of the plate 2 is entered into the groove 8 of the plate 3, and the adjacent edge portions of the

plates

2 and 3 are brought into contact with each other, as clearly shown in the drawings. The connecting plates 5 are then placed against the inner faces of the

wall plates

2 and 3, as shown in Fig. 2, with the

studs

9 and 10 projecting through the

holes

11 and 12, as shown in Fig. 4. This being done, the projecting ends of the

studs

9 and 10 are riveted in the

counter-sunk holes

11 and 12 of the plates 5, as shown in Figs. 2 and 5. During the riveting operation, the blows are struck against the ends of the

studs

9 and 10, in the directions of the arrows, shown in Figs. 4 and 5, thereby displacing the

studs

9 and 10 toward each other and thus drawing the abutting edge portions of the

plates

2 and 3 into close contact with each other through the medium of the

studs

9 and 10 and the connecting plates 5, and forming a very tight joint between the

wall plates

2 and 3.

In Fig. 3 of the drawings, I have shown one continuous connecting plate 6 instead of the series of plates 5, shown in Fig. 2. The continuous connectlng plate 6 extends the full length of the joint between the

wall plates

2 and 3 and it is provided with spaced holes in which all the

studs

9 and 10 are riveted, as a means of securing it to the wall.

plates.

In order that the full thickness of the connecting

plates

2 and, 3 shall not. extend into the, interior of the safe or vault beyond the plane of the inner vfaces of the unain bodies of the wall plates, I provide the

wall plates

2 and 3 with offset portions 13, andl l inthe region of the joint between the plates for the reception of portions of the connecting plates 5 and 6 asclearly shown in the drawings.

hen the parts are assembled, as hereinbefore described, a joint between'the wall plates 2 and?) is provided which is strong and durable and which :cannot be opened 7 from the outside of the safe or vault; and a joint is provided in which relative lateral and edgewise dispbcement or the

wall plates

2 and 3 is prevented by the combined action of the connecting plates 5, the studs ,9 and 10,

nally extending rib projecting into a longitudinally extending groove. in the edge portion of the other plate and preventing lateral separat on ofthe .plates,'and a connect ng plate arranged against the lnner surfaces'o'f the wall plates and crossing thejoint between them, the connecting plate being secured to the wall 'platesby, studs "formed integral with the wall plates and riveted in holes in the connecting plateand preventing ed ewise separation ofthe wall plates. 7

in testimony whereof I atfix my signature hereto,

I ANTHONY KENNEDY.
