Specification of Letters Patent. Patented J an. 16,1912.

Application filed June 2, 1311. Serial No. 630,963.

T 0 all whom it may concern:

Be it known that-I, Aoonr HuSCHAFFERT, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Metal Structures for Doors and Analogous Uses, of which the following is a specification.

This invention relates to the general subj ject of metal oifice furniture of the fireproof type, and has particularly in view a metal structure belonging to this'class, which possesses special utility in the manufacture of doors for safes and analogous purposes.

To this end the invntion contemplates'a metal door structure or the like constructed of a minimum number of parts, while at the same time being readilymanufactured and exceptional particularly adapting the structure for th doors of safes. I

WVith these and other objects in view which will more readily appear to those familiar-with the art-as the nature lof the invention is better understood, the same con' sists in the novel construction, combination,

and arrangement of parts hereinafter more fully described, illustrated and claimed.

Theessential'f'eatures of the invention are necessarily susceptible to structural change without departing from he, scope thereof, but the preferred embodiment is shownin the accompanying drawings, in which Figure l isQa perspective View of a metal door structure, of the safe type, constructed in accordance with the present invention.

Fig. 2 is a cross sectional View on the line} 2-2 of Fig. 1. Fig. 3 is avertical sectional view of the metal door structure, the line of sectionthereof being indicated by the line 3.3 on Fig; 4. Fig. 4 is a vertical sectional view on the line 44:. of Fig. 3. Fig. 5 is a perspective view of one of the wall plates of the door structure, said view also including sectional perspeetivedetails of the top and .side edge port-ions of -the said wallplate.

Fig. 6.-is a similar view. of'the other'wallplate of the structure,-said view'also including sectional perspective details of the bot-f tom and side edge portions. of the said-wall;

plate.

spacedm'etal wall ment 3.

in s. p I The inner wall plate 2 is correspondingly constructed. That is'to say, i

. v el'ement3 of theouter. plate 1. Like "references designate corresponding herein presents a hollow body of substan tially a rectangular form, and preferably having the general design and characteristics of a safe door; However, irrespective of the precise design. of the body of'the structure,- the'latter essentially consists of two parts orsheets of metal adapted to be assembled-and interlocked in the novel manher now to be explained.

Referring particularly to the drawings, itwill be observedthat the body of the metal structure primarily consists. of a pair of plates 1 and 2 arranged in parallel relation and having. interlocking flanged edge portions at the top. and bottom .andsides thereof. While-it" is of 'course im constitute thev outer or'inner wall of the structure, for convenience in understanding the same, the plate 1 may be-designated as the outer wall plate, and the plate 2 as the inner wallplate. v H j Thetwo wall plates 1 and 2 are preferably of the same general configuration, that .is, of a rectangular form,.and according to the present invention, the wall plate 1 is formed at one side edge with a laterally offsetinturned stepped flange element 3, while at its directly opposite side edge the. same wall plated has projected from the same side thereof as the element 3, an outwardly projecting stepped flange element 4, te-r element may be said to be outturned as which latdistinguished from the inturned flange ele- In addition to' the side stepped flange elements. 3 and 4, the outer wallplate l-is provided at the top and bottom edges thereof with the inturned and laterallyofl- I set stepped flange elements 5' and 6 respectively, the said lower. one 6 of said flange elements having drawings, v

as well as in'Fig. 6 of the drawwall plate 2 is provided'at one side edge with f3. laterally offset stepped flange element 7 that is adapted to slidably interlock with, and register inside of, the side flange At itsoppo:v

f stepped flange element, at its opposite side and over the outside of the outturned flange element.- 4 of the lower plate 1. .This con- {att action is fjplainlyfshownin' Fig "of the drawings;

edge; with a laterally, oflset stepped 'top flange element 9 adapted to engage over and; form a complement of the upper flange element of the outer wall plate 1. Also, at its bottom edge the inner wall plate. 2 deformed with. a laterally offset bottom flange element 10 adapted'to fit inside of, andflinterlock with, the lower flange element 6 ofgthefouter wall platel'. I

In assembling the two wall plates #1 and 2, constructed as above, described, he i-nner ,wall plate 2 is slid downwardly up n the in-,

ner face of the wall plate 1 to bringfthe parts into the relation set forth. In this 'op er'ationthe inside stepped flange element 7 of the inner plate 2 passes into position,

,through the combined clearance and guid-= longitudinally arranged interior -brace 12 carried bythe wall plate 2 is carried by the latter into its position bet-ween the two plates by said brace passing through the combined clearance and guiding slot 13 piercing the upper-flange element 5' of the outer plate 1. With the parts assembled as described, adjoining terms may be soldered,

riveted or otherwise rigidly connected.

: wall plates, the outer wall plate being provided at one side edge wlth an inturned edge with an outturned stepped flange element, and with inturned stepped flangeelements at its .top and bottom edges, and the inner of said'wall plates being provided at x one sideedge with aflange engaging inside theinner wall "plate .is provided at its" top of {the inturned flange element of the outer plate, at'itsiopposite side'edge with a' flange engaging overthe outturned flange element lofthe outer plate, and at itstop and bottom edges provided with flange elements which respectively engage over the top flange and inside of the bottom flange of the outer wall plate.

2. A metal structure of theclass described," comprising a pair of spaced metal wall plates, the outer Wall plate being provided at its side and top and bottom edges with stepped flange elements, and having combined clearance and guiding slotsin the top flange element, and the inner of said wall plates !carrying an interior brace piece and pro- {vided at one sideedge with a stepped flange i g p ngag'ing inside of the flange at one side ingslot 11 which pierces the upper flangem" element 5 of the outer wall plate '1. Also, a edge with an inturned hook flange enga ingdg'e of the outer plate, at its opposite side over the flange at the other side edge 0 the outer plate, and at its top and bottom edges 'with. stepped flange elements which respectively engage over the top flange and inside of the bottom flange of the outer wall plate, one side flange and said brace piece ofthe i11-, ner plate being adapted to pass through said slots in the assembling operation.

In testimony whereof I hereunto allix my signature in the presence of two-witnesses.
