Application filed June 20,

To all whom z't may concern: 1

Be it known that I, THOMAS MoG. AIKEN,

' residing at Pittsburgh, in the county of Allej gheny and State-of Pennsylvania, a citizen of the United States, have {invented or dis covered certain new and useful Improvements in Safes, of which improvements the following is a specification.

My invention relates to the construction of safes. I have developed it in application to a filing safe oflight-weightlclass.

.Inthe accompanying drawings Fig. I is a .view in front elevation of a safeot' my invention, standingopen; Fig. H is a plan View of the same safe in the same position, viewed from. above; Fig. 111 is a view in.

Fig. IV is a viewin horizontal section of the safe when in intermediate position, beiJWGGIL ClOS6Cl and. open, and showing also infplanguides for controlling the movement of the parts over the floor upon which the safe stands; Fig. V is a view in detail to larger scale-being asectional view on the same plane with Fig. III and showing the parts in the same relative positions as in Fig.III My invention, stated in, general terms, con sists; in a safe composed of two parts of equal sizeand proportion, and complementaryeach of the other, each constituting areceptacle for articles to be stored and protected, the two halves being 1novable',;alternately to close one upon the other, like the shell and to constitute each the door of the other half, and to open to a position in which both halves are accessible for the introduction, of and'removal ,More minutely. the invention consists in the formation of the meeting edges ofthetwo parts..orhalves, in the locking'device, and in the means for controlling in opening and closing. I I

The safe shown the drawings will'be acquainted with the subbuilt ofinner and outer plates 1 and 2 of steel with interposed filling 30f heat-insulating materlal. I

Comparison ofFigs. I-IV of the drawings twill show this safe to consist of duplicate complementary halves 4; and 5 which may stand open and accessible,as indicated in I and II, or closed, as indicated inf halves are provided and a union more ,Referring observed 0:11 this tcngueand groove formation that clearance may be provided for opening and closing v and: grooves with tapering side walls-,a feature 1921. Serial No. 478,814.

Fig. 111. l Vhen closed, each halfconstitutes the closure for the other.

The walls, as in all safes, are of substantial thickness. The meeting edges of the two with complementary tongue and groove faces. Ordinarily the meeting edges of wall and door of a safe are stepped. Compared with such a stepped engagement, the engagement of the edges ofmy safe parts, characterized by a series of tongues and grooves intermeshing and clamping is manifestly a more secure union completely fire resistant. particularly to Fig. V, it is to be by forming tongues generally advantageous; and if, as in the. case illustrated, the two, safe halves be inged'so as to openandclose'on relatively arc-shaped lines of movement, the inclining of the sidewalls of the groovesis a practical necessity. The meeting edges (which are of steel or faced with steel) will preferably be provideduwith suitable packing, and this packing willordinarily take the form of gaskets of such material as asbestos, indicated at. 6 in Fig. V, lying, when the safe isv closed, between the tips ol the tongues and the bottoms of the grooves. I I

l'locking mechanism is indicated in Fig. where, across ai'larrowspace formed 'for the purpose in the walls of the structure extend pins 7; over which suitableclamping members 8 may make engagement. Conveniently these clamping members are pivoted each on one of two companion pins 7 and are swung to and from clamping or lockingposition by handles 9. preferably have a number of these clamping devices arranged at properly spaced points along the vertical meeting edges,both at the front and at the back, as indicated bv the repeated numerals 8, Flg.

I. I As shown in Fig. Ithe clamping members for the front edges are'borne by one of the two safe parts while the clamping membersfor the rear are borne by the other part (5). This is merely-a matter of convenience. All the clamping members borne by one part be operated by a single handle (9) through operative connections which are not shown, because the supplying .of such detail is obvious. It will be observed that the lockingmechanism; both at front ,1} w ay wh infine mu e;

and rear, is arranged at the inner side of the they are eomposecl. Flames and heat frethick ai -all of the safe, here it is remote qiiently gain access to safes whieh close with from disturbance by heat and 'lronraeeess by apparently abundant -seon1'ity, eonsequent burglars. upon-the fact that under extreme ten1per The safe hal eemayheelogecl an l opene t attire condition-s, the ini ieqiial bodies of safe in any preferred manner.
