A'pplication'filed November 14, l9 2 7; Serial No; 233,066.

This invention relates to'a safe and is more concerned with an individual safe which may be embedded in concrete or similar masonry and kept on the premises, that is, in the wall of a dwelling house or other structure where the one who owns the safe lives. The safe of our invention may be used to house valuables such as ordinarily-are kept in safety deposit vaults.

The construction of safe which wehave devised is one practically impossible to open without possession'of the key which operates theslock used in conjunction with the front end closure of the safe. The construction which we have devised and which has proved practical and completely satisfactory is described in the following description and shown in the accompanying drawing, in which, l i I Fig. -l is a partial vertical section and side elevation, the safe'itself being shown in side elevation and the installation and outer covering door therefor in vertical section.

Fig.2 is a fragmentary enlarged vertical section through the front end of the safe and the closure therefor.

' llig. 3 is a fragmentary horizontal section through the lock used in conjunction with the safe, the operating key for the lock being shown in association therewith;

Fig. 4 is a fragmentary front end view of the safe compartment, the front closure being removed and showing the position of the tumblers of the lock, and

Fig. 5 is a fragmentary horizontal section through the front end and closure of the safe, looking downwardly upon the lugs on the safe and the cooperating engaging members on the closurewhieh detachahly connect "therewith. y Y

Like reference characters refer to like parts in the different figures of thedrawing.

The safe proper comprises a hollow'compartmen't 1 open atits front end, designed to be embedded in masonry like the concrete illustrated at 2, and having an enlargement 3 at its front end; Around the front portion of the compartment it is somewhat thickened and provided with an annular integral ring 4:, back of enlargement 3. At the inner side of the compartment 1 and at least two spaced apart points are integral lugs 5 which are disposed at an angle, as shown, to the front open end of the compartment. Within the 3 closed position.

compartment, at its front end, it is formed with anann'u1ar shoulder 6 where :the enlargement 3 joins therewith. At the front end of the compartment 1 a series of spaced apart cylindrical openings 7 are bored inwardly for distance intot'he' thickened ring portion a in which cylindrical locking tumblers 8 are slidably received, the same beingv normally projected outwardly some distance beyond the front end of the compartment by springs 9 seated in the openings 7. These springs are attached 'at'their smaller ends to the tumblers 8 and at their larger ends fit in the openings 7 frictionallyt so that the tumblers will not fall out of the I openings 7. It will be ibserved, referring to -Fig 4, that theopenings 7 are not the same distance from the longitudinal central axis of the compartment 1 but that each opening from one end opening toj'the other stands out a little farther from such, axis. This is afeaturefof the invention, the purpose of which will later appear,;and which very necessary forthe practical operation of the same. 7

The front end 'of'the compartment 1 may be closed-by a door 1O which has engaging hooked members llat its rear side toengage with the lugs 5 on the inner sides of th'e'compartment l. The door also has a'handle' 12 at its outer side. It will also beobservc d' that thedoor ismachined its'innerside to theshoulder-G, previously described as made at the outer end of the cylinder 1; By turning the i'door 10 about the aids of the compartment the members ll'inay be made to en gage back of the lugs '5 and the door drawn snugly. toclosed position;

At proper places near one edge ofthe door 10 ap'lurahty of openings 14 are bored from theinner side outwardly nearly to the outer side 'of -the said door andso positioned that the same will {come into exact conjunction with the various'openings in the cylinder 1 when thedoor has been turned to its tightly The openings '14 do not extend entirely I through the door 10 but from their. ends other short openings 15 of smaller diameter do ex ring 17 between which and the head of the When this occurs the locking tumblers 8 will be projected outwardly by the springs 9 to enter the openings14, whereupon the door 10 1 cannot be turned in either direction and is locked against turning movement, and therefore, securely locked against detachment due to the fact that the members 11 cannot disengage from the lugs 5 until turned suificient- 1y to have theirends pass completely by each other. It will be further noted that if all of the openings 7 and the openings 14 to correspond therewith were in an arc of the same radius from the center of the compartment, when the first opening 14 came to the first opening 7 a tumbler8 would enter said first opening and lock the device so, that it could not be further moved, one tumbler only being engaged and the door not up to its tightly closed position. It is for this reason that the variousopenings 7 and the openings 14 corresponding thereto are located at different distances from the axis of the compartment and of the door. y I

Unlocking the door is attained by means of a key which is illustrated at the rightin Fig. 1 and also in Fig. 3. The key comprises a flat plate 19, from one edge of which a'plurality of pins 20 of different lengths extend. There are the same number of pins as there are looking tumblers and the diameter of the pins is such that they pass freely through the holes 15to engage the heads of the pins 16.

The pins 16 also are of different lengths and are of such lengths that the combined length of any pin 20 and the pin 16 which it engages V is always equal to the combined length of any other pin 20 and the'pin 16 whichit engages. Therefore, when the key is appliedby inserting the pins 20' through the openings 15. all of the pins 16 are moved whereby their inner ends come to the dividing linebetween the rear side of the door and the front end of the safe 1. This moves the locking tumblers 8 back, as shown in Fig.3, and all of them are fully disengaged from the openings 14, the door is unlocked and may be turned to dis engage from the cylinder 1.

In practice, as before stated, the safe may predetermined position.

be embedded in concrete or other masonry and preferably in the face of the masonry a recess is made which is lined with sheet metal lining 21 having a flanged opening therein extending into the front end of the a enlargement 3 on compartment 1, An additional door 22 of fire proofmaterial closes the recess and lies flush with, the outer side of the masonry wal1,protecting the contents of the safe from fire.

The construction described provides a safe which is substantially secure against unauthorized entrance, and one which can be built in a wall or in a block of masonry as desired.

The advanta es of the construction are obvious I v The invention defined 1n the appended claims and is to be considered comprehenswe of allforms of structure coming within their scope.

We claim: 1.
