IMPROVEMENT IN SAFES.

EDWIN B. HORN, OF BOSTON, MASSACHUSETTS.

Letters Patent No. 60,191, dated December 4, 1866.

. sriiciiPiCATioir.

Be it known that I, Edwin B. Horn, of Boston, in the county of Suffolk, in the State of Massachusetts, have invented an Improvement in Safes ; and I do hereby declare that the following is a full and'exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Naiare.

The nature of my invention consists in a peculiar method,.of construction of a safe, so as to make the same cheap, compact, fire and burglar proof. It consists essentially of a circular or prismatic chamber, so constructed as to revolve freely, when not locked, within an outer casing; said outer casing being made in any convenient shape and of any suitable material. To enable others skilled in the art to make and use my invention, I will proceed to describe its use and construction.

Drawings.

Figure 1 is a perspective view, of my safe showing both doors open.

Figure 2 is a vertical section of the same.

Figure 3 is a horizontal section showing both doors open.

Figure 4 is a horizontal section showing both doors closed. '

Before entering upon a general description of my safe, it may be well to say that it may be constructed in any convenient or desirable form that the principle involved will admit of. I will now describe, by use of the drawings, one mode of constructing my improved safe.

I make of iron or steel an outside case, A, the joints of which are riveted or bolted together in the usual manner. Attached to this outside case are three pedestals, E E' E^zz, into which small truck-wheels, w w' w, fig. 2, are hung; the object of these wheels is simply to make the safe more conveniently'movable. Upon the outer casing a strong door, D, is hung; this door is secured by a lock, L. The locks of this safe may be of any * good pattern now in use, .but should be varied, inasmuch. as they are usually enclosed in tight, casings, so that powder introduced into the key-hole, lodges in the lock, and when exploded destroys the lock., I require locks with open-work cases, so that powder cannot find a lodgement in them. The lower end of the outside case Fas a series of. holes made through it, as shown at h, fig. 2, and by the black dots in figs. 3 and 4 the object of these perforations is to prevent the lodgement of any explosive material within the safe, or,-in case such a lodgement is effected by any means, to offer a free vent in case of explosion. Within the outer casing I construct the case, B, this case is arranged either on pivots, C C^z, as shown in drawing, or upon some system of rollers, so that it shall be free to turn arouriciwithin the outer casing; either one or both of the casings should be fire proof. The inner case, B, has a door, D^z, and a lock, L^z, similar to the door ~ and lock of the outer case. Attached to the inside of the outer, casing is a lock, L^zz; to the outside of the inner case is attached a strip of iron or steel plate, H, figs. 3 and 4, running vertically the whole length of the case; this plate or wing, H, is riveted firmly to the inside case. The wing, H, does not come in contact with the face of the lock, L, but is a short distance from it, so that 'if powder, is put through the key-hole it will not enter the lock, but fall between the cases and through the perforations to the floor. Attached to the outside of the inner casing is a loop, M, figs. 8 and 4, through which the bolt of the lock, L^zz, passes, thus locking the inner to the outer casing. Let us suppose the safe to be open, as shown in fig. 1; to lock it we proceed as follows : the door D^z is closed and locked, then the inner case, B, is revolved in the direction indicated by the d,rrow, fig. 3, until it takes the position indicated in fig. 4, in which case the wing, H, stands just in.front of the lock, L^zz; now throw out the bolt of the lock, L, and the case, B, will become fixed in relation to the outer case; now close and lock the door, D, and the operation is complete.
