for rotating the same, It isunderstood that the door may be of any suitable construction and the bearing .85 suitably located therein. \Vhilethe door is shown solid, it

may, for instance, be built up of laminated gear 91 fixed thereto, spaced from the rear plate by spacing collar90. (See Figs. 2, 3 and 8.) This spiral-gear meshes with a spiral-gear 92 fixed to a cross-shaft 93,

'joui'naled in bushings 9a, 95, fixed to the rear plate of the door in bearings 96, 97. The cross-shaft has a spiralrgear 101 fixed thereto, which meshes with 'a' spiral-gear 102, rotatable with a shaft 103, journaled in the rear plate 75 and in a bearing 104 of the door, a siaacing collar .105 being between the spiral-gear 102 and said rear plate. The construction is the same as that shown in Fig. 9 for rotating the upper locking-bar.

A gear 106' rotates with said stud and meshes with a'gear 107, for rotating a wormgear 108 shown as integral with said gear 107, and rotatable on astud 109 fixed to the rear plate75, by means of a threaded shank 110 extendingfrom said stud andhaving a nut 111 received thereover, the construction being the same as that shown in Fig. 10.

for fixing the stud "7 1 in place: The end of said stud 109 is received in a bearing 112 in the door. The worm-gear 108 'meshe with the teeth of the bar 51.

v A block 115 is threaded to the cross-shaft on. a screw-rod portion 116 of said crossshaft, and is; guided along the rear face of the door, having slide-connection with the rear plate 75 of the door, to prevent relative rotation between said block and the door, whereby said block is moved axially on said cross-shaft. '(See Figs. 2, 3 and 8.)

Endwise movement of the shaft is prevented by contact between the spiral-gears thereon and the bearings of said shaft. Movement of the block in one direction is limited by the bearing 96, and in the opposite directionby a bevel-gear-117 fixed to said. crossshaft, as by a pin 118, the bevel-gear serving as a stop-collar.

The endwise limits of movement of the block correspond to the limits of rotation imparted to the rotatable locking-bars for locating the dividing plane between the barsections i'n the plane of the joint between the door and wall, at one limit of said movement, and locating said bar-sections crosswise of said joint so that the parting plane between said bar-sections is substantially at right angles to said joint at the other or locking limit of movement of the bars.

When at this latter limit of movement, the block is arranged to have an obstructingpart placed there-against to prevent re-. rotation of the bars in release direction, instanced asthe bolt 121 of. a suitable combination lock 12.2, operable from the outside of the safe by a handle 123 011 a suitable spindle 1241-, connecting the handle with the tumbler mechanism of the locln This 0bstructingpart may take the form of any ther suitable obstructing mechanism or locking mechanism, as of acombination lock, ortiine lock, or other suitable locking device.

. When the obstructing part is in obstructing rel" "ith the bar or bars rotated in their sockets with the door closed, the door is locked, and when the obstructing part is removed from obstructing relation with the block the bar mechanism ma be 0 aerated to J 7 J 1 rotate the bars and unlock the door.

Wle pa 1 a l l e ba a1 u g +1 a bq 4 a b +1 employ er, tie same may c iota c y n16 handle 86 by continuing the operative mechaism to said. bars, instanced as accomp. seed by means of upright- shafts 125, 126, 'ournaled in bearin s 127 128 fixed to the l b 7 rear plate so of the safe-door, and having 'iinate ends, said bevel-gears meshing '1 the bevel-gear 117. Spirahgears 18 1, 185, are fix ;lto the respective ends of said shafts, and esli with spiral gears 136, 187.

The spii' gear 136 is fixed to a shaft 141 andhas a-spur-gear 142 thereon, fixed to rotate therewith. (See Fig.9.) Theshaft isrotatable in a bearing 1 13 in the plate '75 and in a bearing 1 14 in the door. It is provided with a flange 145 which, with the gear 14-2 and a washer 1&6, fixes the shaft endwise in a recess 14? between the plate 75 and the'door. A spacing-collar 1 18 is located between the spiral-gear and' the plate. The construction of the shaft 103 and the parts mounted thereon is similar to the shaft 1&1 and the parts mounted thereon.

The spur-gear 142 meshes with a spurgear'151, which has a worm-gear 152 thereon. These combined gears rotate on a stud 153, which has a reduced threaded end 154; received through a hole in the plate 7 5. A nut 155 is threaded over this reduced threaded end for clamping the stud to said plate, the plate being located between the nut and a shoulder 156. The forward end of the stud is located in a bearing 157 of the door. The worm-wheel 152 meshes with the gear 71 on the locking-bar 52 for rotating the same.

'Siiniliar means, reversely placed, are provided for rotating the locking-bar 53, indicated by similar but primed reference numerals;

I have GXQHIPllfiQCltllG means for rotating the locking-bars as mounted on the door,-although 1 do not limit myself to such location ofsaid rotating means, ass'aid rotating &

means may be mounted in the wall oi? the door-opening. and said lockingdiars may be rotated 'lrom the outside of the same instead of trom the inside of the same as exemplilied.

In operation. when the door is opein as illustrated in Fig. t. the sections ot' the locking-bar are respectively received in the wall of the door-opening and in the door. the parting planes of said sections being preferably coincident with the iaccs of the joints between the wall and the door.

Swinging the door into closed position and manipulating the handle 4:0, forces the door into the wall of the door-opening. and causes seating in the joints of the same. and also causes the sections of the locking-bars on the door to register with the sections ot the locking-bars in the *all of the dooropening. for coaetive relation between the mating faces of said sections.

hen now the handle 86 is turned, the worm wheels on the door. which mesh with the gears on the locking-bars. cause rotation of the locking-bars. the rotation of the sections oi? the locking-bars on the door be ing transmitted by contact between the coaeting faces to the sections of the lockingbars in the wall of the door-opening, whereby the sections of the locking-bars are arranged across the joints between the door and wall for locking the door, as shown in Fig. 3.

During such locking movement, the block 115 has axial movement imparted thereto along the screw-portion 116, for forming a space between said block and the bearing 96. whereupon, by manipulation of the combination lock, the belt 121 is moved into obstructing relation with said block, tor maintaining the bolt-works in locked relation.

Rotation of the bars beyond the desired angle of rotation is prevented by contact of the block 115 with the bearing 96. when the parting planes of the locking sections are coim-ident with the joints between the door and wall tor unlocked relation of the door, the block 115 contacting the bcvclgcar ll'T when said bar-sections are located in the locked relation as shown in Fig. 3.

As an element of safety the spindle 833 is preferably a thin spindle. which would be severed if force were applied to the handle 86 tor rotating the same in excess of that ordinarily employed for rotating the locking-bars. in order to minimize or a void the danger oi burglarious rotation of said locki ng-ba rs.

My improved locking means is simple and ell'ective. and provides a locking bolt extending lengthwise throughout subshmtially the entire length of the joint between the door and its wall.

In my improved device, further, the doorfaces of the joints are held in close im- 'iingement againstthe wall-:liaces o'l said joints throughout said joints, by substantial bars having close impingement with the walls of the recesses in the door and wall in which said bars are located, :liorming uniting; faces of substantial area throughout substantially the lengths of said joints, and resisting movements of said door in burglarious attempts, by means of the pressure bar system or otherwise, for preventing the ilormation of suliicient space in the joints to permit introduction of explosive or other opening means.
