SAFE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 331,480, dated December 1., 1885.

Application filed April 14, 1885. Serial No. 162,198. (Modeh) To all whom it may concern.-

Be it known that I, CARL DIEBOLD, of Canton, in the county of Stark and State of Ohio, have invented certain new and usefullmprovements in Safe Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in safe attachments, the object being to provide a presser-bar and double door-hinges, with the rear hinges rigidly connected by an axial rod, a stop arranged to limit-the outward movement' of the rear portion of the hinges, to the end that in closing the safedoor the wrists of the presser-bar will enter the respective grooves in the cam-blocks automatically, and the door by means of the presser-bar on its near approach to its seat will be kept parallel with the seat.

A further object is to provide acombination of mechanism whereby the dial of the combination lock and the bolt-shifting lever or handle may be arranged on opposite sides of the presser-bar, although the lock and the internal connections with the bolt-shifting mechanism may be directly behind the presser-bar.

With these objects in view my invention consists in certain features of construction and in combination of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of a safe with my improvements thereon. Figs. 2 and 3 are elevations in transverse section of the door and casings, the former showing the position of the door when the presser-bar is in position to be operative, and the latter showing the door closed. Fig. 4 is a View in perspective of a portion of the safe, showing the rear portion of the hinges at the limit of their outward movement, and showing the rear cam-block and the grooves therein. Figs. 5, 6, and 7 are views in perspective respectively of the cam-blocks, presser-bar, and attachments. Fig. 8 is a view in perspective and partly in section of the mechanism respectively for connecting the dial and hand-lever with the lock and bolt-shifting device.

A represents the safe, and B the safe-door,

groove 9.

with the dial 5, for operating the combinationlock, and the lever or handle I), for shifting the door-bolts. The door and casing are tongued and grooved, as shown, with packing, a, in the groove of the latter, arranged in the usual manner, and this construction necessitates the employment of some means for keeping the door parallel with its seat as itapproaches and engages the latter. For this purpose I employ double hinges and a presser-bar arranged as follows: The parts 0 of the hinges are attached to the door and jointed to the parts 0 in the usual manner. The latter is rigidly attached to the axial rod 0, that is journaled in the parts 0, and the latter is secured to the safe, as shown. With this arrangement of parts the two sets of hinges of course move in unison. A lug, 0 attached to the rod 0, or to one of the parts 0, as may be preferred, by its engagement with the safe limits the outward movement of the rear portion of the hinges, while the forward joint of the hinges is left free.

D is the presser-bar, arranged in the form of a rock-shaft, and journaled in the blocks (1, that are attached to the door and provided with the hand-lever D. The enlarged ends of the bar, have wrists d and (i that are in line with each other, but are eccentric with the axis of the presser-bar. These wrists engage grooves respectivelyin the cam-blocks E and F, that are attached to the safe on the opposite sides of the door, as shown. These blocks have each a vertical groove, respectively, e and f, and lateral grooves. e and f, the former, 6, leading from the upper portion of the groove-e forward to the face of the block E, and the groove f leading from the groove f rearward. The relation of parts is such that with the lever D turned down, as shown in solid lines in Fig. 6, the wrists d and d are above the axis of the presser-bar, and the wrist d is in position to enter the With this position of parts when the door is closed by hand the wrists d and d will be respectively in the upper part of the vertical grooves eand f, after which, if the lever D is turned up to or toward the position shown in Fig. 1, and in dotted lines in Fig. 6, the wrists will descend in the respective grooves e and f, and by reason of their eccentricity with the presser-bar will force a limited distance, the rear portion, 0, of the double hinge need not move but a short distance, and is therefore limited, as aforesaid, by the lug 0,- but in so doing an important end is attainedto wit, the axial line of the forward part of the hinge is kept so near the safe that the wrist (1 will always enter the grooves in the block F, and this, too, without 'any guiding of the door by the operator or otherwise.

Double hinges have heretofore been used on safe-doors, some of which would admit of the door engaging the safe edgewise if it were not guided by the operator. With the construction shown the door, when swung to, however carelessly, will automatically assume its proper position to engage the seat, and the wrists of the presser-bar will find their way to their respective places in the cam-blocks.

Where this mechanism is attached to large doors for the outside of safes or vaults, it may be advisable to use two presser-bars, arranged the one above the other on the door, and in such case the levers D might be connected by a bar or link, so'that by moving one lever, D, both resser-bars would be simultaneously operated. This mechanism is also used on small doors inside the safe or vault when it is necessary to economize the space on the face of the door, so that after attaching the hinges there will be room for locating the dial, lever b, and the presser-bar, and have them all accessible and convenient. The presser-bar should be located across the center of the door, to equalize the pressure on the seat. WVith small doors the combination-lock is likely to cover the greater part of the inside of the door, and must therefore be located about centrally, at least in a vertical direction, and the only available space on the outside of the door for the dial and bolt shifting lever are respectively above and below the presserbar.

To connect the dial and lever with the internal mechanism, I have had recourse to a modification of devices for which Letters Patent of the United States were granted to A. G. Burton, dated February 1, 1870, No. 99,400, the essential features of which are shown in Fig. 8.

The spindle H of the dial has a gear, H, and the lock-spindle I has a gear, I, with one or more intermediate gears, h. The spindle 'J of the lever D has a gear, J, and the spindle K of the bolt-shifting mechanism has a gear, K. By arranging the gears H and one or more intermediate gears, h, above the gear I the dial is brought above the presser-bar approximately, as shown in dotted lines, Fig. 1. By arranging the gear J below the gear K, and if necessary using one or more intermediate gears, the lever D may be located below the presser-barfor instance, as shown in Fig. 1. WVith this construction of parts the dial, bolt-shifting lever, and presser-bar may be conveniently located 011 a door so small that the available space on the door is about all taken up with these parts and the necessary room for operating them.

WVhat I claim is 1. In safe attachments, double door-hinges, a stop to limit the outward movement of the intermediate part of the hinges, a presser-bar arranged on the door, and suitable engaging cam-blocks arranged on either side of the door and so arranged that in operating the door the latter will automatically swing to its place in the casing and the wrists or ends of the presser-bar will automatically enter the respective places in the cam-blocks, substantially as set forth.

2. The combination, with a door and a .presser-bar secured thereto, of the spindles H, I, J, and K and the gearing the above parts being combined. and arranged substantially as described.

In testimony whereof I sign this specification, in the presence of two witnesses, this 4th day of April, 1885.
