SAFE OR VAULT.

SPECIFICATION forming part of Letters Patent N0. 788,103, dated April 25, 1905.

Application tiled August 19,1903. Serial No. 169,962.

Re it known that i, H umn' Denise Hmmm), a citizen of the United States, residingl in Plainlield, in the county of Union and State of New Jersey. have invented certain new and useful lmprovements in Safes or Vaults, of which the following' is a speciiicatitm.

This invention relates to safes or vaults; and it more particularly relates to the locking or bolting mechanism thereof, the object of the invention being to provide an improved safe or vault the door of which is maintained in its scat by bolting' mechanism controlled b v means project-ing' throughthe wall of the safe, which same means is also effective to so operate the mechanism that the Vfurther operation of the bolts thereby cannot be effected until a predetermined period.

A further object of the invention is the provision of locking or bolting mechanism controlled b v a single spindle, which is also operative to effect disconnection of part of the boltoperating means, thereby to prevent the boltwork from being operated except at a predetermined period.

A further object of the invention is the provision of an improved safe or vault employingl but a single spindle in connection with a time-lock for controlling' the operation of the bolting' mechanism, such spindle also controlling' means 'for preventing the operation of the bolts until the time-lock operates such controllinel means.

One of the principal features of the present invention is the provision of a safe or vault in which the door, whatever may be its particular means for locking' such door in its seat, is under the control of a single spindle, the rotation of which in one direction will effect the locking' of such door, while the rotation thereof in an opposite or reverse direction side of the door. Fig. 3 is a detail view of the bolt-controlling' means in that position which permits the door to be closed and bolted. Fig'. A is a detail view of a part of such bolt-controlling' means, illustrating' more particularly its connection with the time-lock. Fig. 5 is a detail view of the bolt-controlling means in that position which the parts assume after the door is bolted and the spindle has been operated to make disconnection of the parts to prevent further operation of such bolts by the spindle. Fig'. 6 is also a detail view of the bolting' mechanism in that position which the parts assume after the timelock has run down, at which time the manipulation of thel spindle will withdraw the bolts. Fig. 'T is a sectional view taken in line l a, Fig. 3, looking` from the under side thereof; and Fig. S a detail view of the clutch members detached. Fig. t) is a detail perspective view of the clutch-operating means.

Similar characters of reference indicate corresponding' parts throughout the several tig'- ures of the drawings.

The present improvement has for its object more particularly the provision of a burglar-proof safe or vault in which the bolting mechanism for maintaining the door in its seat is controlled by a single spindle, thus obviating,l the necessity of providing' two or more spindles passing through the wall-as, for instance, the door of the safe. ln the safes heretofore patented by me several spindies have been used, one of which operated the bolts. ln the present instance I utilize this bolt-imeratingl spindle notonly to manipulate the bolts, but also to operate the mechanism after the bolts have been properly f thrown, so that the retraction of such bolts cannot be effected by the spmdle, such spindle thus having a duplex 'functionwnamelw will prevent the door from being' unlocked r ldisconnection of the operatlng mechanism in the drawings accompanying and forming until a predetermined time.

part of this specification, Figure l is a sectional view of a part of a safe and its door,

the latter closed, with this improved mechan- Fig. 2 is a cross-seci to throw or retract the bolts and to effect a whereby the bolts cannot be retracted except ata prialetermined period AMsuch, formstance,

i as when the time-lock mechanism has run down, which will operate to reestablish connection of the parts and permit the spindle to retract the bolts and unlock the door.

The safe or vault comprises a body2 and a door 3 of any suitable construction, but preferably similar to that heretofore patented by me in which the body is provided with an elongated jamb 4, formed by a pair of beads or projections 5 and 6, and which jamb has a suitable offset or step 7 and bolt-receiving recess or groove 8. The door comprises a body 9 and a iange 10, the latter having suitable bolt-receiving openings 12 and a centrally-located boss 13, adapted to cooperate with the inner ends of the bolts to prevent their withdrawal except by a rocking movement thereof, and which bolts work in the openings 12 with their inner ends connected to a rotary disk 14, provided with wormteeth 15 in engagement with a worm-shaft 16, carrying at one end a bevel-gear 17. l/Vhen this shaft is rotated, thedisk 14 will be partially rotated and the bolts withdrawn or protracted, as the case may be. For rotating this worm-shaft 16 I provide suitable clutch mechanism, one member of which forms part of the bevel-gear 17, in mesh with a bevelgear 18, located on the inner end of the aetuating device or operating-spindle 19, passing through the door and squared on its outer end to receive a suitable crank. The bevelgear clutch member is loosely mounted upon the worm-shaft 16, so that the turning of the spindle will merely rotate this gear without imparting movement to shaft and bolts, to effect which the companion clutch member 2O is splined or keyed to the worm-shaft 16. Vhen the clutch members are in engagement, the rotation of the geared clutch member will rotate the shaft, thereby to retract or protract the bolts. To prevent the rotation of this worm-shaft by means of the gear when the bolts have been thrown and to effect the rengagement of such clutch members on the running down of the time-lock mechanism, it is necessary that suitable mechanism be provided. The mechanism which in the preferred form thereof herein shown and described is adapted to accomplish this purpose comprises a member or lever 25, having a forked end in engagement with the sleeve or collar 26 of the sliding clutch 'mem ber 20, its opposite bifurcated end being mounted on a short shaft 27, having also mounted thereon between the furcated ends of the member 25 member or lever 28. Each of these members 25 and 28 is provided with an extension or arm 29 and 30, respectively, between which is located aspring 31, the tendency of which is to force the sliding clutch member into engagement with the geared clutch member through the medium of the member 25. The member 28 has a stopface 28', adapted to engage a stop-face 25/ of the member 25 and move the latter, with its clutch member, away from the bevel -gear clutch member at the proper time. From the foregoing it will be seen that the member 25 is movable independently of the member 28.

To separate the clutch members, a spring 32 is provided eective to force the arm 28 to the right, Fig. 5, and thereby the arm 25,

through the medium of the stop-faces 25 and' 28, hereinbefore referred to, with its clutch member, away from the lower clutch member.

The spring 3l could be dispensed with, if desired, as it is not essential, although it is of some use under certain conditions to prevent strain on the clutch-shifter, and the main features of this improvement still be present without the necesssity of making levers or arms 25 and 28 as separate members. In fact, the various details could be more or less departed from without changing or effecting the scope of this invention.

Projecting into the slotted end of the member 28 is a pin or projection 33, secured to one end of a plunger 40, having mounted thereon between a fixture or bracket 34 and a collar 35 a spiral spring 36, a part of said plunger being formed with a notch 37 for the reception of a suitable catch 38, having an arm 39 in operative connection with the timelock mechanism 50. The time-lock mechanism (not shown in detail) is effective, as it runs down to throw the catch 38 in the direction of the arrow a to release the catch from the plunger 40, whereupon the plunger is thrown by its spring in the direction of the arrow b and throws the member 28 to the left, Fig. 6, thus permitting the spring 31 to move the member 25 so that the clutch members are brought into engagement. Should the position of the two-clutch members be such, however, that the teeth 41 thereof will not pass into engagement, the spring 31 will maintain the parts in close engagement, so that as the bevel-gear, with its clutch member, is rotated the sliding clutch member will be moved into position sooner or later to engage its companion clutch member, and thereby permit the operation of the bolts. Vhen, however, the spring 3l is not used, this result is obtained by the spring 36, in which case the arms 25 and 28 would be rigid with each other.

To maintain the meshing of the clutch members and permit the bolts to be properly thrown to lock the safe by the operation of the spindle when the plunger is locked in its retracted position, at which time ordinarily the clutch members would be disengaged, suitable means is provided, comprising in the present instance a stop member 45 having a stop-surface 46 cooperating with a stop-surface 47 on the arm 28 and effective when such arm is thrown to the right on the retracting of the plunger to force the arm 28 to the lett and hold it there against the action of the spring 32, and thus hold the clutch members engaged. As long as these stop-surfaces 46 and 47 are in engagement the clutch members will be maintained in mesh, and consequently the bolts can be thrown or retracted, and to TOO IIO

prevent this suitable means are provided comprising a ratchet-disk 48, mounted on the worm-shaft 16 and shown herein as forming a part of the bevel-gear 17. A pawl 51 in the 'form of a lever is held in engagement with said ratchet-disk b v a spiral spring 59. and has a slot 52' at one end for the reception of a suitable guide pin or screw 53, its opposite end being' connected to the stop member 15, the upper end of which is fulcrumed to a shaft or stud. On turning the spindle in one direction the worm-shaftwill be rotated, the bolts thrown out, and the ratchet turned in the direction of the arrow c, Fig. 7, thus permitting' the pawl to slip over the teeth of such ratchet. After the bolts have been fully thrown a reverse movement of the spindle rotates the ratchet-disk in the opposite direction and shifts the pawl-lever, which is permitted b v its slot, thus throwing lower part otl member i5 to the left, and thereby the stop-surface i6 from the stop-surface :t7 of the arm 28, thereby permitting the spring 3Q to shift the arm Q8 to the right, Fig. 5, and through the medium of the stop-faces 25 and 2S on said arms and 28 shift the arm 25 to disengage the clutch members. The relatively longspaces 42 between the clutch-teeth #i1 g'ive sutlicient play or loose motion to permit this reverse movement of the spindle without withdrawing the bolts. lVhen it is desired to withdraw the bolts, the clutch members being in engagement, the organization is such, as will be observed, that when the pawl-lever has been shifted as far as possible it will not interfere with the rotary movement of the spindle to retract the bolts, since the pawl-tooth will have been pushed suticiently far to the left, Fig. 7, to permit the ratchet to pass away from it. From this it will be seen that the same spindle which throws the bolts when the clutch members are in engagement also controls the separation of such clutch members when the bolts have been completely thrown.

To set the mechanism so that on the closing and bolting of the door it cannot be opened exceptwhen the time-lock runs down, the stop member -15 is connected by a suitable link 5T with the plunger 40, it havingl a slot 5S working upon the pin 33, so that when the pawl-lever is moved into the position shown in Fig. 5 this slot permits movement of the link upon such pin 33 without effecting' the position of plunger 40. For operating this stop member 45 to set the mechanism a suitable crank or handle is provided.

1n the operation of setting' the mechanism, the door being open, the handle 60 is moved into the position shown in Fig'. 3, thereby moving' the stop member 15 into the position y shownin said Fig. 3, whereupon the link 5T pulls the plunger @t0 against the resistance ot' its spring into the position shown in said Fig. 3 to permit the catch 38 to fall into position and lock the plunger in such position. At this time, of course, the stops 46 and t7 will be engaged and the clutch members also in engagement. The door is then closcd,and on the operation of the bolt-spindle in the proper manner the bolts will be thrown to bolt the door. After the door is closed the spindle is reversed, thereby turning the ratchet-disk in the opposite direction to shift the pawl-lever, as hereinbefore set forth, thus disengaging the stops A16 and $7 and the clutch members, Fig. 5, so that the rotation of the bevel-gears by the spindle will not have any efl'ect upon the bolts. `When the time-lock runs down, it throws the catch 38 into the dotted-line position, Fig. et, releasing the plunger, which moves into the position shown in Fig. 6, carrying' the arm Q8 with it, which throws the two clutch members into engagement, so that the rotation of the spindle will withdraw the bolts. To prevent the opening of the safe at this time or during the day when the time-lock is ofi', a suitable combination-lock mechanism may be used locking the hinge or door of the safe.

From the foregoing it will be seen that by a comparatively simple mechanism and by the use of one spindle only the bolts may be either retracted or thrown out and mechanism also operated to prevent the operation of the bolts by this same spindle.

The single-spindle principle could be used with various forms of doors and with various forms of locking or bolting means for maintaining such doors in their seats and could also be used with rotary doors, the rotation of such spindle in one direction serving to lock the door against rotation after it is properly seated, while the rotation thereof in an opposite or reverse direction acting,either through a positive connection or otherwise, as in the present case, to dog or prevent the unlocking' of such door until a predetermined period, which may be determined by the use of a suitable automatie or time lock similar to that shown and described herein, if preferred.

To prevent the rotation of the worm-shaft by vibration, som'e suitable dogg'ing or locking' 'means may bc used, similar, if desired, to any of those shown in my contemporaneously-pendingapplications,SerialNo.173, 23T, tiled September l5, 1903, and Serial No. 182,952, tiled November 2S, 1903.
