JAMES HENRY DUNNINGTON, OF LOUISVILLE, KENTUCKY.
Application filed January 14, 1922.
To all 'whom it may concern:
Be it known that I, JAMES H. DUNNING- TON, a citizen of the United States,residing at Louisville, in the county of Jefferson and State of Kentucky, have invented new and useful Improvements in Burglarproot Safes, of which the following is a specification.
This invention relates to a burglar proof safe, the general object of the invention being to provide means whereby, when a burglar attempts to blow open the safe, the force of the explosion will open vents so that' th; gas can escape without damage to the sa e.
Another object of the invention is to so arrange and form the vent closing means that they will form projectiles, when forced out by the explosion, which are likely to strike the burglar and kill or injure him.
Another object of the invention is to provide the safe with a layer of lire resisting` material so as to prevent the safe from being opened by a blow torch.
This invention also consists in certain other features of construction and in the combination and arrangement. of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specilically pointed out in the appended claim.
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a horizontal sectional view through a safe constructed in accordance with my invention.
Figure 2 is a section on line 2 2 of Figure 1.
Figure 3 is a perspective View of one of the vent closing members.
Figure 4 is a view of the plugs for closing the outer ends of the vents.
As shown in these views the safe is composed of the outer casing 1 and the inner casing 2 which are spaced apart and are fastened together by the rivets 3. The space between the casings is illed in with a layer 4 of cement or the like which is so made as to resist the action of the flames from a blow torch or the like. The inner casing forms the receiving compartment of the safe and the front of the outer case is enlarged, as shown at 5, to receive the main door 6.
Serial No. 529,234.
The compartment in the inner casing is closed by the door 7 as usual. Each door is provided with the combination locking means which include the bolts 8, the handle 9 and the knob 10 which controls the combination means. Each door is hingedly connected with a part of the safe and the hinged side of each door is provided with the hooks 11 for engaging sockets in the safe so as to prevent the door from being removed if the hinges are destroyed. rfhe hinged edge of the door 7 engages a recess 12 formed in the inner casing and the outer door has a rib 13 thereon for engaging a recess 14 in the outer casing, this arrangement of parts also acting to prevent the doors from being opened if the hinges are destroyed. The inner door is spaced from the outer door so as to leave a chamber 15 between the two doors and the outer door is provided with a layer 16 of cement between its first and second plates. These plates are connected together by the rivets 17 and the third plate is connected with the rst plate by the rivets 18 which are connected with the inner face of the first plate. The second and third plates are spaced apart to form a chamber to receive the bolts. Strips 19 are placed around the outer edges of this chamber and similar strips are placed around the layer 16, these strips having their outer faces flush with the edges of the door. I also locate strips 2() between the inner and outer casings to conceal the layer 4. The inner door is composed of two plates which are separated to form a chamber to receive the locking means of said door.
Holes 21 are made in the inner and outer casings, the holes in the inner casing being of smaller diameter than those in the outer casing and these holes receive the projectiles or closing members 22 which are formed of two diameters so that the smaller part of each projectile will engage the hole in the inner casing with the shoulder formed by the two parts engaging the outer face of the inner casing. W'hen in place the inner end of each projection will be flush with the inner face of the inner casing, and its outer end will be spaced from the outer face of the outer casing so that a closing plug 23 may be inserted to hide the projectile. Some of these projectiles are so placed that they will be acted upon by an explosion occurring in the chamber 15, these projectiles being longer than those in the small part of the safe. I/also locate some of these projectiles in the inner and outer doors, as shown at 22, those in the inner door extending entirely through the door while those in the outer door only reaching as far as the space which receives the locking means.
vWhile the drawings show the projectiles arranged horizontally I prefer to arrange them at an angle with their outer ends above the planes of' the lower ends so that the projectiles will remain in place under the action of gravity.
From the above it will be seen that if a burglar should attempt to blow open the safe by boring a hole or holes in the same and pouring in nitro-glycerine or any other explosive, the force of the explosion will blow out the projectiles, thus forming vents which will permit the gas to escape without damage to the safe and these projectiles are likely to strike the burglar and either kill or injure him.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
lhat I claim is:-
A safe of the character described comprising an enlarged front portion merging into a smaller rear portion, an inner casing having a plurality of openings therein, an outer casing having a plurality of openings therein ot' a larger diameter than the openings of the first mentioned cast-ingv and lbeing in alignment therewith, an intermediate layer of concrete between the casings and being provided with openings aligning with the openings of both casings, projectiles formed of two diameters designed to fit the respective aligned openings and being so positioned within the openings to provide a space between the outer face of the outer casing and the outer face of the projectiles, a plug adapted to lill this space and being so arranged to hide the outer face of the projectiles, a pair of sectional doors closing a chamber between themselves, one f said doors being constructed similar to the construction of the portions and concealing means for the concrete.
In testimony whereof I affix my signature.
