Patented Friar. i6, MM5.

Application filed July 25, 1914. Serial No. 852,980.

T0 all whom t may concern Be it lznown that L ALFRED P. Hens- Tnrrnn, a citizen of the United States, residing at Norwood, in the county of Hamilton and State of Chio, have invented certain new and useful Improvements in Safe- Loclring Devices, of which the following is a specification.

lily invention relates to improvements in devices ,tor operating the locking and closing devices for the doors of vaults, safes and the like.

The object of my invention is to provide certain improvements in Such devices which will maire the same more convenient while at the same time presenting an eii'ective arrangement in which it is impossible for the bolts to be thrown when the combination or combinations of the locking devices are not open, it also being impossible to manipulate the pressure device to cause pressure in the direction for opening the door to be exerted before the bolts have been thrown into inoperative position.

Other objects of my invention relating to the construction of my improved devices will appear more fully from the following specification.

In common practice, the combination loclr operating devices in vault and safe doors are generally located to the right of the door and the bolt arbor to the lett of the door, the pressure device, whereby the door is iirmly pressed into its opening, being operated from the central portion of the door. In accordance with my invention, the bolts are operated from a central posi.- tion, whereby the whole bolt operating mechanism is effectively balanced. The combination locking devices and also the eccentric pressure device referred to are operated by revoluble members which are con centric with each other and with the bolt arbor, the various hand-wheels or means tor operating these parts being arranged in line with each other at the central portion of the door. lVith this arrangement in .opening the door the graduated hand-wheel operating a combination lock is first operated, and it two combination locks are used, the hand-wheel for the second lock is next operated, alter which the hand-wheel for throwing the bolts is rotated and after that the hand-wheel for operating the eccentric pressure device for withdrawing the door from its opening is operated, these various operating hand-wheels being in line with each other and readily manipulated in proper sequence as stated. In closing the door, the operations referred to above are repeated in reverse order. i

In order that a clearer understanding of my invention may be had, attention is lier by directed to the accompanying drawings forming part oi this specification and illustrating certain preferred embodiments of my invention.

ln the drawings, Figure l represents a horizontal cross-section through a vault or safe door taken on line l-l of Fig. 2, the door being provided with a pair of locks governing the operativeness of the bolts, and means for manipulating the same, Fig. 2 is a rear view of the door, Fig. 3 is a iront view of the same, Fig. el is a partial section taken on line l-fl of Fig. 3, Fig. 5 is a del tail section taken on line 5 5 of Fig. 3, Fig.

6 is an enlarged section taken on line 6 6 of Fig. 2, Fig. 7 is a sectional detail on an enlarged scale illustrating a manner of constructing the bolt arbor and locking spindles illustrated in Fig. l, Fig. 8 is a partial sectional view similar to Fig. l of a modification in which a single combination lock only is employed and Fig. 9 is a partial rear elevation of the same.

Referring to the drawings, the door l has extending therethrough the lock spindle 2 on the outer end of which the dial d is secured preferably by providing the spindle 2 with a squared enden which the dial 4 is mounted, the dial being secured to the spindle as by means of the flat headed screw et. The gear 5 is secured to the other or inner end of spindle 2 by any suitable means, the function of this gear being to operate one of the combination locks as will be described. Surrounding the locking spindle 2 is a hollow sleeve or lock spindle 3 carrying at its inner end a gear 6 adapted to operate a second combination lock. A small hand wheel 7 is secured to the outer end Ot hollow loci; spindle 3 by any suitable means, preferably by threading the hub S of hand wheel i on the end of the hollow loch spindle 3 and securing the same thereto by means of the locking set screws 9. Surrounding the hollow lool; spindle 3 in my preferred construction is the hollow bolt arbor 10 which carries on its inner end a spur gear 11, set into the 'frame of the door in iront of the loclr plate 12 which is secured to the door by suitable means such as the set screws 13. The gear 11 engages with racks for throwing the bolts, as will be more fully explained hereafter. The bolt arbor 10 is provided on its forward end with a hand wheel 1&1-, the hub of which is secured to the end of the bolt arbor 10 by suitable means such as the headless set screws 15.

Surrounding bolt arbor 10 in my preferred construction is the hollow sleeve 16 provided on its outer end with the pilot wheel 17 secured to the end oi' the sleeve 16 by suitable means such as the headless screws 13. Sleeve 16 has secured thereto a miter gear'19 whereby the eccentric pressure device may be operated as will be eX- plained. l

A detail of the preferred arrangement of the locking spindles and bolt arbor is shown in Fig. 7. As illustrated in Fig. 7 and Fig. 1, the spindle 2 is provided with a collar 20, and hollow spindle 3 is formed oi two parts in alinement with each other and having enlarged portions 3 and 32 surrounding the collar 20 and provided with engaging clutch-teeth as indicated. Correspondingly, the hollow arbor 10 is formed of two alined portions having enlarged portions 10 and 102 surrounding the enlarged portions 3, 32 of spindle 3 and provided with engaging clutch-teeth. A nut 21 is mounted about bolt arbor 10, surrounding the'collar 102 of the arbor to prevent endwise movement. oi the arbor and spindles.

As stated, the gears 5 and 6 serve to operate combination locks which govern the operativeness of the bolts of the door in the usual manner. Lock casings 22 and 23 are secured to lock plate 12, gearing within lock case 22 being rotatable through intermediate gears, such as 2li, 25 and 26 from gear 5, and gearing within case 23 being rotated from gear G by means of a chain of gears such as 27 and 28, the gears 2e, 25, 26, 27 and 23 being protected by a plate 29 covering the same and secured to the door as shown. Bial e has graduations on its outer rim, as also has hand-wheel 7, so that the locks within cases 22 and 23 may be set to desired combinations and operated by turning dial l and hand-wheel 7 to the proper numbers. Universal bar 30 is connected at 31 and 32 to lock bolts 33 and 3l extending into loclz casings 22 and 23 and movable into or out of the casings by the combination locking devices therein when properly set. The gear 11 on bolt arbor 10 operates the various bolts of the door, when permitted to do so by the previous actuation of the locking devices, by any suitable connection.

gear l1, referring to Fig. 2. Upper vertical bolts, not shown, are integral with or secured to the carrying-bar 35. Carrying-bar 37 has vertical rack 33 integral there lith, meshing with gear 11 on the left side thereoi, the bottom vertical bolts of the door (not shown) being integral with or carried by bar 37'. Bar 35 is provided with rack-teeth 39 and y-lO on its right` and left sides respectively, with which mesh gears 41 and 42 respectively, studded to the door, which gears mesh respectively with racks i3 and 44 integral or carried by the right and left carrying-bars 45 and 4b, which carry the right and left horizontal bolts L7 and L13 respectively. Similarly carrying-bar 37 is provided with rack- teeth 49 and 50 on its right and left sides, with which mesh gears 51 and 52, studded to the door, which respectively mesh with racks 53 and 5l, also secured to or integral with carrying-bars l5 and'l, car-l rying horizontal bolts 117 and ei-S. |The bolts are all represented as shot in Fig. 2. 0bviously the rotation of gear 11 results in the outward or inward movement of all the bolts together, when movement of the carryingbars is permitted by the locking devices. The various bolts are slidably mounted in supporting bars secured to the door, those for the horizontal bolts being shown at 55, 5G, and 57, 53. lt should be understood that this construction is given as illustrative and that any suitable operative connection between the various bolts ora the door may be used, the novelty of the device, so far as the operation of the bolts is concerned, residing in the centrally-located bolt arbor l0 carrying gear 11 operating the bolts, whereby a direct or central drive for the bolts is provided, and the complete bolt-operating device is balanced.

rlhe movement of bar 30 in accordance with the operation of the combination locks, referred to above, serves to operate a locking lever or equivalent device into or out of position to prevent or permit sliding movement ci the bolts. ln the construction illustrated, a bell-crank lever 59 is pivotally oonnected to bar 30 by a link 60 and is pivoted to the door at 61. lThe bell-crank has a horizontally extending arm 62, which constitutes the lock-lever referred to, the outer end of arm 62 extending through an opening in support or inner bolt bar 55, the end of arm G2 extending into al hole in a sliding plate 63, which is mounted to slide on supportinga plate 6st, having an L section on both sides of plate G3, and secured to inner bolt bar 55. Slide-plate 63 has an opening therein through which the extension 65 of slidingplate @6, secured to carrying bolt plate l5, is adapted to pass when the locks have been los operated to permit the movement of lockbolts 33 and and the movement of slideplate G3 to vplace the opening in plate 65 in line with member 65. Thus it is necessary to operate lock- spindles 2 and 3 to operate bar 30 and bell-crank 59 to place plate 63 in unlocking,` position before the bolts can be retracted. The double locking` device is arranged as is well known, so that both looks must be operated to open the door, or may be arranged so that one lock will open the door, by shifting` link 60 to the other stud shown at 67, and if lever 59 should be blown olf the door, plate 63 will drop into position to make it impossible to open the door, in the well-known manner.

rlfhe eccentric pressure device is operated as stated by the rotation of sleeve i6 carrying miter gear 19. The latter engages with miter gears 68 and 69 mounted on vertical shafts 70 and 71, the gears preferably being` mounted in a gear box 72 through which shafts 70 and 71 extend. lin the form of nr invention illustrated, pressure is applied to the door at four points to seat the same in its opening as closely as possible when the door is to be locked, the pressure devices also serving` to open the door. 1n the construction illustrated, shafts 70 and 71 are connected by worm-gears with horizontal shafts 73 and '74a mounted in bearings 75 and provided with the usual eccentric pins 76 mounted in suitable curved tracks 77 secured to the wall surrounding the door opening` so that actuation of pilot-wheel 17 will result in the application of pressure at the four corners of the door to seat the door closely in its opening or to more the door from its opening', the door being' hung' from the wall in the manner usual with safe or vault doors of this character.

ln Figs. 8 and 9, l iave illustrated a modification in which a single lock and accordingly a single lock-spindle are employed. As there illustrated, the lock-spindle Q having collar LX) formed thereon and carrying' gear 5 on its inner end is surrounded by the bolt arbor 10 carrying gear 11, the second lock-spindle 3 and connected parts described in connection with Figs. 1 andA being omitted. Bolt arbor 10 is formed of two parts which may be joined together by clutch-teeth as described in connection with A l, or which may be formed as illustrated in Fig. 8 by screwing the two alined parts of arbor 10 together and locking the same with a suitable set-screw, nut 21 being used to prevent endwise movement of the spindle and arbor as described in connection with `Fig. 1. ln this construction, since only a single combination lock in case is used, the bar 30 described in connection with the first form of my device is not necessary, locking-lever G2 in this case forming one arm of a bell-crank, the other arm of which is pivoted to the lock bolt 33 slidable into and out of lock-case 22.

ln both forms described of my invention. it will be obvious that a well balanced efiicient and convenientform of mechanism is provided in which the various hand-operating mechanisms are located in line with each other at the central part of the door in position to be readily operated in proper sequence as has been described.
