ACTUATOR-LOCKING MECHANISM FOR SAFES OR VAULTS.

SPECIFICATION forming part of Letters Patent No. 788,106, dated April 25, 1905.

Application filed Hoveniber 28, 903. Serial No. 182,952.

lield, in the county of Union and State of New 3 5 Jersey, have invented certain new and useful Improvements in Actuator-Locking Mechanism for Safes or Vaults, of which the follow- 1 ing through the door, and by means of which in is a specification.

ihis invention relates to the bolt mechan- IO ism of safes or vaults, the object of the invention being to provide improved means for locking or dogging the bolts.

A further object of the invention is the provision of improved means for locking the bolt- 5 actuator mechanism, thereby to lock or dog the bolts.

The present organization is an improvement in part upon that shown and described in my application, Serial No. 173,237, filed September 15, 1903, and while it maybe used in connection with one combination-lock it is herein shown assembled with a pair of such locks. it is to be understood, however, that it can be used either with a single or double spindle safe or vault with equal facility.

in the drawings accompanying and form- 3 ing part of this specification, Figure 1 is an inside view of a vault or safe door, its bolting mechanism beii'ig provided with this improved Fig. 2 is a cross-sectional view Fig. 3 is dogging mechanism, parts of the back being i an enlarged detail view of a part of the boltf actuating mechanism and this improved locking means. Fig. is a cross-sectional view taken in line b Fig. 3, illustrating the wormshaft and a part of the locking means. Fig.

5 is a detail view of a part of this locking;

spring means, and Fig. 6 is a detail view showing 4 the manner of supportii'ig a part of such locking means.

Similar characters of reference indicate corresponding parts in all the figures of the drawings.

The door 2, which may be of any desired formation, is shown as an integral structure, comprising a body 3 and a flange 1, the flange being provided with bolt-openings 5 for the passage of the bolts 6, which bolts are pivotally connected at their inner ends to a worm- 5 wheel 7, in mesh with a worm-shaft 8, suitably mounted upon the door, carrying a pair of loosely-mounted bevel-gears 9, in mesh with which is a pair of bevel-gears 10, each mounted on the inner end of a spindle 12, projectthe worm-shaft and the worm-wheel are operated to shift the bolts when the proper combination-lock has been set. A pair of splined clutch members 13 are mounted upon the worm'shaft and cooperate with companion clutch members 1+1, formed as a part of or on the hubs'of the loosely-mounted bevelgears 9, whereupon when either of the splined clutch members 13 is in engagement with its 5 companion clutch member 1% the worm-shaft may be rotated. The splined clutch members are shifted by a pair of clutch-shifters 15, each connected with a combination-lock 16, whereby on the proper operation of either combination-lock the worm-shaft can be rotated.

To prevent the worm-shaft which constitutes a part of the actuating means from being rotated by vibration when the splined clutch members are disassembled from the loosely-mounted clutch members carried by the bevekgears, suitable means is provided, which in the present instance comprises a device having locking-faces, which will be designated herein as a ratchet"or ratchet pinion or wheel 20. Suitably mounted in position to engage this ratchet-wheel is a locking member, designated herein as a lockingpawl 21, maintained in permanent engage- 5 ment with such ratchet-wheel by a suitable Connected with the clutch-shifters 15 are two lovers 23 and 2st, one secured to each, the inner ends of which are in position to engage the free end of the pawl 21. 9 1n the form shown the inner end 25 of each lever has a cam-face or is beveled and cooperates with an inclined or beveled face 26 of the pawl. \Vhen eitherof the clutch-shifters is moved by its COIilbll'ltLtiOfl-lOCli to swing the splined clutch member 13 into engagement with the clutch member 14:, the pivoted lever 23 or 24 which is connected with that particular clutch-shifter will be shifted or oscillated so that its inclined face 25 will be swung or moved into engagement with the inclined face of the pawl and raise this end of the pawl up, and consequently depress or carry the opposite end of such pawl away from the ratchet, thus unlocking the worm-shaft and permitting said shaft to be rotated on the turning of either spindle in a manner readily understood. To permit both levers to swing in the same direction, one of the levers, as 2 is pivoted at 30, while its free end is pivoted, as at 31, to a lever 32, connected with the clutch-shifter, so that when the lever 32 is moving toward the bevel-gear the pivoted end 31 will be moved in the same direction, and thus throw the inclined face into position to raise the pawl.

From the foregoing it will be seen that on the operation of either clutch-shifter the pawl will be shifted by that lever which is connected therewith against the action of its spring free of the ratchet and that when the clutchshifter is moved so as to carry the splined clutch member away from its companion clutch member the inclined face of the lever will permit the pawl to be returned to its normal locking position by means of such spring. In the organization shown and described in the application hereinbefore referred to the splined clutch member constituted a part of the locking mechanism, in consequence of which when two combination-locks are used, as illustrated in Figs. 6 and 7, both splined clutch members had to be connected together for the reasons therein stated; but in the present instance this is avoided by mounting the ratchet-wheel directly upon the worm-shaft and rigidly secure it thereto, whereby the operation of either clutch-shifter without the operation of the other will unlock the worm, and thereby the bolts.
