I Specification of Letters Patent.

Patented Aug. '7, 1906.

Application filed February 20,1905. Serial No. 246,605-

To a whom it may concern:

Be it known that I, EMIL A. STRAUSS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safe-Bolt-Actuating Mechanism; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in actuating devices for radially-arranged bolts such as are commonly used on circular safedoors; and it consists in the matters hereinafter described, and pointed out in the appended claims.

In the accompanying drawings, Figure 1 is an interior face View of a part of a safe-door provided with radially-arranged boltwork and actuating devices therefor embodying my invention. Fig. 2 is a sectional view taken upon line 2 2 of Fig. 1. Fig. 3 is a detail section taken upon line 3 3 of Fig. 1. Fig. 4 is a perspective view of a part of the bolt-actuating ring with one of the gear-segments attached thereto. Fig. 5 is a detail section taken upon line 5 5 of Fig. 2. Fig. 6 is a sectional view taken upon line 6 6 of Fig. 1.

As shown in said drawings, A indicates a safe-door of circular form, B B two bearingrings attached to the inner face of the door, one near the outer margin thereof and the other somewhat inside of said margin, and C C a plurality of radially-arranged cylindric bolts, which fit and slide endwise in bearingapertures formed in the said rings B B.

D indicates a radial endwise-movable dogging-bar attached to one of the bolts 0 and extending inwardly toward the center of the door.

M indicates a central supporting-plate adapted to form a support for the dogging devices and for a combination-lock or automatic ti me-lock which may be employed for controlling the movement of the bolts.

E indicates a bolt-actuating ring which is located between the outer and inner bearingrings B and B and extends between the several bolts C O and the face of the door. Said ring is pzrovided with a plurality of gear-segments E E, that extend from the side face of said ring into the spaces between the bolts. Each of the bolts 0 C is provided with lateral gear-teeth 0 cut in the side faces of the bolts between the ends of the same and lll 1tghe space between the two bearing-rings F F F indicate gear-pinions which turn on axes perpendicular to the safe-door and located between the guide-rings B B in the spaces between the bolts, said gear-pinions intermeshing with the lateral gear-teeth c on the bolts and also with the gear-segments E. Said gear-pinions serve to transmit motion from the actuating-ring E to the several bolts, so that by the turning of the ring simultaneously an equal endwise movement is given to all of the bolts for casting or retracting the same.

The gear-pinions F are mounted on the studs F, which are rigidly affixed to the door and project inwardly from the inner face thereof. The said gear-pinions are supported by said studs at a distance from the door necessary to bring them in line with the central axes of the several cylindric bolts. In other words, the said gear-pinions are located midway between the lanes of the inner and outer faces of the cy indric bolts, this location of the gear-pinions F enabling the lateral gear-teeth c on the bolts to be formed or cut in the convex side faces of the same laterally opposite their central axes.

The gear-segments E are elevated above the inner face of said actuating-ring E a sufficient distance to bring them in position to intermesh with the said gear-pinions F. Said gear-ring E is located adjacent to one of the bearing-rings B or B, preferably the external ring B, and a plurality of antifriction-rollers G G G are provided to afford an antifrictionbearing between the actuatin -ring and the adjacent bearing -ring. Sai antifrictionrollers in the construction shown in the draw ings are mounted on the actuating-ring and engage the inner face of the bearing-ring B. Said antifriction-rollers are, moreover, located within recesses formed in the inner ed on bearing-pins g, which extend through ends with the actuating-ring E and at their outer ends with said ear-segments, as clearly seen in Fig. 2. T is location and arrangement of the antifriction-rollers in recesses in the gear-segments has the advantage that the rollers are concealed or covered faces of the gear-segments E and are mountsaid recesses and are engaged at their inner vided at the inner face of the door with a transmit rotary motion to the gear-pinion F gear-pinion H, which intermeshes with gearteeth d formed on one side of the doggingbar D and also intermeshes with one of the gear pinions F. When the spindle H is turned, the said gear-pinion H serves to engaged therewith and from the latter to the actuating-ring E, and also serves-to give endwise motion directly to the dogging-bar D.

. The said actuating-spindle H is shown as arranged in line with the inner guide-ring B and having a bearing at its inner end in said ring, which latter is recessed at its side adj acent to the inner face of the door to receive the pinion H, as clearly seen in Fig. 3.

The dogging-bar D is connected with the inner end of the bolt C, to which it is joined by means of a stud I, having screw-threaded engagement with the bolt and projects be yond the inner face of the same to engage an aperture in the adjacent end of said bar D, In order that the outer end of the said bar may be guided or held from lateral movement and the gear-teeth d thereon held in proper intermeshing relation with the actuating-pinion H without bringing lateral pressure on the bolt C, to which the said bar is connected, said bar carries a guide-roller J, which projects from the inner face of the said bar and engages a radial guide-groove on the door. Said guide roller is conveniently mounted on the end of the stud I which proj ects from the inner face of said bar D to receive said roller, and a radial guide-groove J is preferably formed or sunk in the inner face of the door beneath the outer portion of said bar D.

-Any suitable form of dogging device may be employed in connection with the doggingbar D, the construction illustrated in these parts being as follows: Said bar D is provided at its inner end with a stop-lug D, which projects through a radial slot m in the supporting-plate M. Mounted centrally on said supporting-plate are two rigidly-connected dogging-arms K K, one of which is adapted for engagement at its free end with the stop-lug D on the dogging-bar D, the other end of which is adapted to engage a like lug D on a corresponding oppositely-arranged dogging-bar D which may be connected with an opposite bolt on the door in the same manner as the bar D. The dogging-arms K K are shown as provided with a thought necessary to illustrate the same.

4 rigid radial arm K, which is connected with a link L, through the medium of which motion is transmitted to the dogging-arm from a combination-lock or a time-lock. Such combination or time lock may be arranged in any usual or preferred manner, and it is mit 13 will of course be understood, inasmuch as the dogging-bar D is attached to and moves with one of the bolts 0 and all of the bolts have operative connection with and are moved by the actuating-ring E, the dog ing of the bar D will hold from movement a l of the bolts. The drawings illustrate two dogging-bars D and D but any other number may be used as desired or preferred, it being of course understood that any number of dogging-arms K may be employed to correspond with the number of dogging-bars present in any particular case.

The bolt-actuating devices described have i the advantages of being simple and strong in structure, durable and reliable in operation, and of giving a symmetrical and attractive appearance to the boltwork as a whole.

I claim as my invention 1.
