SAFE-DOOR-LOCK'ING MECHANISM.

Specification of Letters Patent.

Patented July 24, 1906.

Application filed May 23, 1904. Serial No. 209.156.

To all whom it may concern.-

Be it known that I, ORVEY PRICE, a citizen of the United. States, residing in Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Safe-Door-Operating Mechanism, of which the following is a specification.

This invention relates to bolt mechanism for safes or vaults, the object of the invention being to provide an improved system of safe or vault door bolt mechanism.

Another object of the invention is the provision of improved means for blocking the bolt mechanism against retraction.

Another object of the invention is the provision of improved means for operating such bolt mechanism.

Another object of the invention is the provision of improved bolt mechanism effectively locked and blocked by independent means, the operation of which independent means and the actuation of the bolt mechanism itself being obtained through the medium of a sin le spindle supported independ ently of the blocking means.

A further object of the invention is the provision of an improved bolting mechanism the bolts of which are effectively wedged in their protracted position without swinging such bolts and dogged and blocked in such position against retraction and which mechanism is simple in its construction, organization, and operation, but powerful in its ac tion.

In the drawings accompanying and forming a part of this specification, Figure 1 is a rear view of the safe or vault door with its back plate in position, the bolting mechanism being shown in dotted lines. Fig. 2 is a cross-sectional view taken in line a a, Fig. 1, the bolts being shown protracted. Fig. 3 is a similar view to Fig. 2, but with the bolts shown retracted. Fig. 4. is a partlyperspec tive sectional view taken in line B B, Fig. 1. Fig. 5 is also a rear view of the door with a part of its back plate broken away and showing one form of a combination and time lock in position. Fig. 6 is an enlarged sectional detail view taken in line 0 c, Fig. 5. Fig. 7 is an enlarged detail view of the operating means for the detents and clutch. Fig. 8 is a perspective view of the gear-ring. Fig. 9

is a side and top face view of the traveling head. Fig. 10 illustrates end and side views of the link by means of which the traveling head operates the bolts. Fig. 11 is an en= larged cross-sectional view of the doggingbolt and its operating-pinion. Fig. 12 is a detail view of an improved form of dog ing or locking means for the ring and traveling head, and Fig. 13 is a sectional view taken in line (I d of Fig. 12.

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

The present invention is in part an improvement upon the bolting mechanism patented by Henry D. I-Iibbard and in part an improvement upon the doggingmechanism shown and described in the application of myself and WValter Gaston, filed April 11, 1904, Serial No. 202,491, now Patent No. 792,072, dated June 13, 1905:

The present improvement is designed in part to provide a bolting mechanism in which the bolts may be shifted lengthwise or radially into their protracted position in such manner that a powerful wedging action thereof is obtained without the necessity of swinging the bolts in order to accomplish this desirable result whereby the door will be drawn firmly to its seat and wedged therein, while the bolts when in such position will be dogged and blocked against retraction by vibration or otherwise and which bolts should the actuating means be displaced will still be maintained in their locking position against retraction.

The door 2 maybe of various constructions, but in the preferred form shown it is a one piece or integral circular structure which will be preferably formed of unmachineable metal, such as manganese steel, and comprises a body 3, having a flange 4., the latter provided with bolt-openings 5 for the passage of radial bolts 6, the shanks or inner ends of which are shown in the present instance guided by guiding devices which act to maintain the bolts against displacement. For this purpose when the door is made of unmachineable metalsuch, for instance, as manganese steel, which is hard and when heat-treated very tough.as it is not practicable to drill the same to provide threaded openings for screws or bolts, the body of the door is shown fitted with a machineable-metal part, preferably in the form of a soft-metal insert 7, shown maintained in position by a wedge or wedges, such door-body having a dovetailed recess 8 centrally located, in which the insert is located. A plurality of inserts could be used, if desired, in place of the single insert shown. Each bolt 6 comprises a head 9 and a shank 10, each sideof which shank is provided with a groove 11 for the reception of guiding blocks 12, forming tracks screwed or bolted to the soft-metal insert. By this means the bolts are maintained against sidewise movement, as well as retained in position against displacement, during their in and out movements. It will of course be obvious that the reverse of this construction could be used, if desiredthat is to say, the guides or tracks could be formed on the bolts and the ways on the blocks.

In the present instance, as hereinbefore stated, the bolts are not shifted or swung 'sidewise in order to obtain the radial movement thereof, and consequently the boltheads may be fitted with precision in the bolt-openings formed in the fiange of the-door and, in fact, may be ground to a .matching fit.

For sliding the bolts improved means is provided, comprising a traveling member or head 13. This traveling head is mounted upon a rotatable screw 14, journaled upon a spindle 15, screwed into the soft-metal insert at one end and headed in the rear of the back plate 50 at the other end, preferably passing through a cap 16, fitting into an opening in the back plate and bolted to such back plate. FiXedly secured to this screw 14 is a pinion 17 for rotating such member to shift the traveling head. Pivotally secured to brackets 18,

carried by the back plate, is link mechanism comprising a plurality of links 19, one for each bolt. Each of these links has separable connection with its bolt, the connection being such that on the displacement of the back plate under an explosive charge or otherwise the links will be Withdrawn from the bolts without shifting such bolts. For this purpose the bolts and links are provided with protuberances 20 and recesses 21, in the present instance the recesses 21 being formed in the bolts, while the protuberances 20 are carried by the links, forming a oint somewhat similar to a ball-and-socket joint. Each of these links has a cam formation, being provided with a pair of cam-faces 22 and 23, cooperating with a pair of cam-faces 24 and 25, formed on the traveling head, one of such faces, as 24, being wedge-shaped to engage the inner ends of the bolts, which are inclined or beveled, as at 26.

Referring to Fig. 3, when the head or actuator, as it may be termed, is moved toward the body of the door the inclined camface 24 engages the cam-face 22 of the link 19 and slowly but powerfully moves the links on their pivots to shift the bolts into their protracted positions, as shown in Fig. 2, and when such bolts have been partly forced home the inclined cam-face 24 of the traveler then comes into engagement wvith the in clined inner "ends 26 of the bolts and by such direct engagement forces the bolts outwardly with a wedging action, the bolt-recess in the jamb of the safe-body and the ends of the bolts being formed to secure this highly-important result. When such bolts are firmly seated home and the traveler at rest, the rib or cam-surface 25 acts to block the retraction of such bolts. This traveling head is thus not only a bolt-actuator but a bolt-blocking device. -On the reverse movement of the traveling head it first releases or unblocks the bolts and then by the engagement of its'cam-face 25 with the cam-faces 23 of the links shifts the bolts inwardly into their retracted position. (See Fig. 3.) From the foregoing it will be seen that this traveling head is a non-rotatable reciprocatory actuator effective indirectly through the links at one period to shift the bolts outwardly and to retract them inwardly and at another period by direct engagement with the bolts to force them outwardly and wedge them in position and finally effective to block the bolts by its direct engagement therewith against retraction and that, owing to the inclined or beveled surfaces of the traveling head and the inner ends of the bolts, such bolts will be forced home and held in such position with the door wedged in its jamb against the possibility of inserting nitroglycerin into the joint around such door, and thus insure a fluid-tight oint. For the purpose of shifting this traveling head a spin dle 93, projecting through the body of the door and located at one side of, and therefore independently of, the traveling head, is provided. gear 27, preferably formed as one member of a clutch 35, the spindle having its inner end mounted in a cap 28, bolted to the back plate 50. This gear 27 is in mesh with another gear 29, mounted on'a stud 30, projecting from the back plate, and which latter gear is in mesh with the pinion 17, fixedly secured to the screw on which the traveling head is mounted. The other member 36 of this clutch is splined to the spindle for rotation therewith, and when said clutch members are in engagement the rotation of the spindle will through the medium of the gearing rotate the screw, and thus shift the traveling head to actuate the bolts.

For the purpose of shifting the splined clutch member 36 into and out of engagement with the loosely-mounted member 35 a clutch-shifter 37 is provided, it being con nected to a short rock-shaft 38, to one end of which the clutch-shifter is secured and to the other end of which a lever 39 is connected,

On this spindle is loosely mounted a the opposite end of which is pivoted to the bolt 40 of the combination-lock 60, so that when the combination-lock tumblers =..re properly set and the bolt 40 shifted the clutch-shifter will be operated to throw the splined clutch member 36 into engagement with the loosely-mounted clutch member Then on the rotation of the spindle the traveling head will be moved to shift the bolts.

For the purpose of adding additional security to the safe or vault a dogging mechanism independent of the blocking means is provided. This dogging mechanism is substantially similar to that shown and described in the joint application hereinbefore referred to, it comprising a plurality, preferably one for each bolt, of rotatable bolts 7 O, threaded into soft-metal inserts 71, fitted in the flange 4 of the door, so that it comprises what may be properly termed rim dogging mechanism. The outer ends of these bolts carry pin-ions 7 2 in mesh with the teeth 73 of a gearring 7 4, supported by the door, in the present instance by means of the back plate 50, from which project a series of antifriction-rolls 75, working in a track or way 76, located on the inner side of such gear-ring 7 4. By this means the ring is not only supported, but its rotary movement facilitated. For rotating this gear-ring it is provided on its interior with teeth 7 7, which are in mesh with the gear 27, loosely mounted on the spindle 93. Each of the door-locking bolts is provided with a tapered opening 78, into which the tapered end 79 of its dogging-bolt fits. From the foregoing it will be seen that on the operation of the single spindle, which is shown tapered and tightly fitting into an opening in the door-body, being wedged therein by a threaded and pinned collar 80, the gear-ring will be rotated, provided the clutch members are in engagement, through the medium of the gear 27 to rotate the dogging-bolts, and at the same time the gear mechanism connecting this spindle with the screw onwhich the traveling head is mounted will be operated to shift the traveling head.

The dogging-bolts and the traveling head are so organized and timed that such doggingbolts will enter the openings in the lockingbolts at the proper moment and will be withdrawn therefrom before the bolts are retracted by the traveling head, as will be readily seen from an inspection of Fig. 2, since the traveling head must move from the position shown into position to enga 'e the cam-surfaces 23 of the links before said bolts are started. During this movement the dogging-bolts are rotated and withdrawn.

In order to prevent any possible premature withdrawal of the dogging-bolts or shifting of the traveling head, and thus unlock the main bolts, suitable locking means is provided. In one form it is shown in the nature of detent mechanism comprising a pair of locking fingers or detent's, one for locking the dogging mechanism and the other for locking the blocking mechanism against movement. Both of these locking-fingers are preferably operative at the same time and by the same means, in the present instance by the combinationlock. For this purpose an arm 85 is pivotally mounted on the bracket which car ries the clutchshifter rock-shaft, one end of which arm is connected with a projection 86, carried by such rock-shaft,the other end carrying a short shaft 87, to the free end. of which is secured a detent device 88, adapted to engage a part of the blocking mechanism, shown in the present instance as the pinion 17, fixed to the screw, such detent device projecting between the teeth thereof, and thus preventing rotation of such pinion, and thereby movement of the screw and the traveling head. Also connected to this pivoted arm 85 is a lever 89, connected at its opposite end with a spring-actuated detent 90, working in a recess 91 of the flange of the door. This detent device in its normal operative position projects into a recess 92 of the gear-ring, and thus prevents rotation thereof. On the proper setting of the combination-lock the movement of the bolt thereof shifts the splined clutch member 36 into engagement with the loosely-mounted clutch member 35 on the spindle, and at the same time the means just described operates to withdraw the detent device 88 from the gear 17 and to shove the gear-ring detent 90 inwardly against the action of its spring, and therefore away from the gear-ring, thus simultaneously releasing both the pinion and the gearring, so that on the turning of the spindle at this time both the gear-ring and the pinion 17 will be operated to release the doggingbolts and unblock the main bolts and retract such bolts to permit the door to be opened.

Since the movement of the traveler is limited at one point by the body of the door and at the other point by the gear 17 and as this traveler is shifted through the medium of the spindle and the gear carried thereon and as this gear also operates the gear-ring, it follows that the movement of the rotary dogging-bolts is also limited, so that such bolts must necessarily have a certain limited movement and cannot, therefore, be rotated into position where they would fail to cooperate with the main bolts at the proper time. Furthermore, the tapered recesses in the main bolts and tapered ends of the rotating bolts cooperate in such manner that the doggingbolts will properly fit into such main bolts at a predetermined period, or if they should not the cooperating tapered surfaces will enable the dogging-bolts to work their way into proper position.

From the foregoing it will be seen that the same spindle which is effective to operate the main bolts is also effective to control the dog- IIO . dogging the gear-ring.

ging and blocking of such bolts, so that this main bolt locking and blocking means is controlled by a single spindle, while at the same time a very powerful and effective boltoper ating means is provided and which means cannot be vibrated so as to shift the main bolts from their protracted positions if perchance the back plate and operating means should be displaced or blown inwardly into the body of the safe under the action of high explosives, for, as will be seen, the back plate, the traveling head, and connectinglinks could all be displaced, together with the gear-ring, but the rotary dogging-bolts would still lock the main bolts against retraction.

In conclusion it is to be understood that the various details may be more or less changed without departing from the spirit or scope of this invention. For instance, the screw upon which the traveling head moves may be so secured in position that the displacement of the back plate by an explosive charge or otherwise would not interfere with such head, as the outer end of the bolt now supported by the cap which is bolted to the back plate may be supported on the inner side 01 such plate in some suitable manner, so that when the back plate is displaced the opposite end of the bolt, being supported in the soft-metal insert, would maintain the blocking member in position to assist securing the bolts against retraction.

In Figs. 12 and 13 is shown what I consider a very desirable dogging or locking means for the traveling head and gear-ring, which dogging or locking means, like that hereinbefore described, are simultai'ieously operated through the medium of the clutchshifter and combination-lock in a manner previously set forth. This means, however, instead of comprising a detent mechanism can be more properly considered a stop mech anism, since it includes a plurality of stop devices. A rock-shaft 95 is suitably supported. in position by the back plate and is provided at one end with a locking stop or lug 96, shown in the form of a crank-arm projecting into position to engage one of several projections or stops 97, carried on the inner side of the gear-ring. Then these stop members are in engagement, further rotation of the ring is prevented. The ring is provided with a number of these projections 97, so that some one of them may come into engagement with the stop-arm at the proper time. The foregoing comprises the stop mechanism for The stop mechanism for dogging the traveling head comprises a disk 98, having a plurality of projections or stops 99, this disk being fixed either to the .screw upon which the traveling head is mounted or fixedly secured to the pinion or gear 17. Cooperating therewith and ca ried by the rock-shaft 95 is a stop or stop-arm 100, which when the stop devices 96- and 97 of the gear-ring and rock-shaft are in engagement are also in engagement to prevent the rotation of the screw. On the proper manipulation of theclutch-shifter the rock shaft will be rocked and the

stops

96 and 100 thrown out of engagement with the

stop devices

97 and 99 to permit the gear-ring and screw to be rotated.
