WILBER E. ARNOLD, OF MADISONVILLE, OHIO, ASSIGNOR TO THE VICTOR SAFE & LOCK COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.

VAULT AND STRONG-ROOM DOOR.

To all whom it may concern:

Be it known that I, \VILBER E. ARNOLD, a citizen of the United States, and residing at Madisonville, Hamilton county, State of Ohio, have invented certain new and useful improvements in Vault and Strong-Room Doors; and I do declare the following to be a clear, full, and exact description thereof, attention being called to the accompanying drawing, with the reference characters marked thereon, which forms also a part of this specification.

This invention relates to certain improve-.

ments in the construction of doors for vaults and strong-rooms, the particular feature concerning the manner of supporting such a door, so that it may be conveniently manipulated.

In the following specification and particularly pointed out in the claim at the end thereof will be found a full description of my invention, together with its manipulation, parts and construction, which is also illustrated in the accompanying drawing, in which Figure 1, is a horizontal section through such a door and the frame to which it is fitted, the door being shown in closed position. Fig. 2, is a similar view and shows the door open. Fig. 3, is a front-view of the door in its closed position and as it appears in Fig. 1. Fig. I, is a vertical section through the door and its frame, taken on a line l-4: of Fig. 1, and looking in the direction of the arrow shown there. Fig. 5, shows a top-view of the door-frame. Fig. 6, is a section taken on a line 6-6 of Fig. 2, the lower part only of the door being shown.

A shows part of the front wall of a vault or strong-room, a door-opening a being provided to permit access.

B is a door-frame preferably rectangular and set into this opening in the wall, its op posite upright sides b-b of the frame forming the jambs of the door.

C is the door fitted to this frame and movably supported so that it may prevent passage through the opening surrounded by the frame when closed and permit it in either direction when open.

The construction of the door and of its frame is so devised that either or each of them may be made in form of a casting,

which may be of non-machineable metal like manganese steel for instance.

Flanges 8-8 extending outwardly from the frame are provided which receive between them the masonry of wall A and thereby serve to hold the door-frame se curely seated in the wall-opening.

The door is in form of a rectangular slab of solid metal, convex between its longer, upright edges, so as to form in substance a segment of a cylinder. It is provided on one of its upright edges with a lip 9 and on its other edge with a shoulder 10.

In the closed position of the door as shown in Fig. 1, its li 9 strikes against a shoulder 11, and shou der 10 on the door which projects outside of the periphery thereof abuts against a shoulder 12, both shoulders projecting inwardly from the door-j ambs. A tight closure is thus obtained which prevents the introduction of explosives at the upright edges of the door. The

door has a swinging movement for opening or closing, it movlng horizontally in its own plane as best shown in Fig. 2. It is supported for such purpose on pivots, one 13, seated in the sill l4: and the other 15 being seated in the lintel 16 of the doorframe. Engagement of the door with these pivots is by hubs 17 carried at the ends of arms 18, which project from the inside of the door at lower and upper edges of it and preferably radially arranged. The horizontal edges of this door meet the edges of forwardly extended arts 19 and 21 of sill and lintel respective said extended parts completing the closure when the door is in the closed position shown in Fig. 1. These opposite edges meet in a manner which prevents the introduction of liquid explosives, for which purpose tongues and complementary grooves are provided thereat. The grooves are arranged to be inverted so as to be incapable of retaining liquid explosives and to prevent also the accumulation of dust and dirt. For such purpose a groove 22 is provided in the lower edge of the door, to receive a tongue 23 which projects up wardly from the front edge of the extended sill. Above, a groove 24: is provided in the underside of the forwardly extended part of the lintel to which is fitted a tongue 20 at the upper edge of the door. It will now be noted, by observing Fig. &, that upwardly open joints are avoided by this arrangement which would favor the introduction of explosives in liquid form.

Means, which by reducing friction and by carrying part of the weight of the door facilitate its manipulation, may be provided at its lower edge. They may be in form of ball or roller bearings provided within groove 22, or such rollersmay be provided in a manner as shown at 25, they traveling upon the sill and its forwardly extended part. The sill by preference is also extended-rearwardly as shown at 26, to provide a surface for these rollers to travel upon.

Smaller doors of limited weight may be manipulated directly by hand, suitable handles or knobs being provided for the purpose.

For heavier doors suitable mechanical devices are provided as for instance a rack 27 on the outer side of the door, into which a pinion 28 is fitted which is supported on a, bracket 29, connected to adjacent parts of the door-frame. A handle 31; is provided, p e er b y e e able,v w ere y the pin n. may be rotated,

ui able locking means, usua ly ne r more bolts 82, to, be actuated by a time-lock 83., may be provided. These bolts are seated in the door near one of; its edges and adapted;

to move into sockets, 34 provided in adja cent parts of the door-frame, said sockets being so: located as to be opposite the ends. of the bolts when the door'is in closed position.

Where a number of bolts are used, they are all attached to a bar 85;, whereby they are simultaneously; moved, said bar being operatively connected to the time-lock, to be actuated thereby.

When the door and its frame are made of non-machineable metal as before alluded to, I provide for inserts of machineable metal which are placed during the casting of these parts, to permit machine and hand tool-work where such is necessary, as for instance to provide for the guide-ways and sockets of the locking-bolts, the attachment of the time-lock, for the formation of rack 27 and for the connection of bracket29 and for bearings for rollers 25.

For all other Work, finishing of the door and the frame and fitting of the edges of the former into this latter, grinding is resorted to. V

The edges of the door-frame on the inside of the vault are extended outwardly all around to form an attaching flange 36 which permits connection with the vault-lining 37.

A section of removable flooringy38 may be provided which during business hours may be placed into the door-way, to coverthe lower arms 18 as show-n in Fig. 6, so 3 as to provide for a level and even passageway through the door+opening., It may rest on these arms and also on feet 39.

I am familiar with the construction of a i plicatijonbeing prior to, mine, the scope of.

my claim should be construed accordingly j and so as not to include any of the matter claimed in said prior application.

Having described my invention, I claim as new:

In door construction for vaults, the combination of a door in shape of a cylindrical segment having converging arms projecting,

from its innerconcave side near its horiz-ontal edges and hubs supported by these arms in a position so as to be concentric to this concave surface, a rectangular door-- frame having sockets located opposite each other in the horizontal members, and pivots seated in these sockets and engaging the hubs mentioned in amanner to permit the door to swing in its cylindrical plane.

In testimony whereof, I hereunto affix my signature in the presence of two witnesses.

WILBEB. n. ARNOLD.
