LOCK.

i Application filed December 30, 1922, Serial No. 609,813. lRenewed October 21, 1927.

This invention relates to improvements in locks, and more particularly to recording' locks which are used in conjunction with ordinary locks. Recording locks, as iswellknown, are provided with mechanism for making a record upon a time cha-rt or otherwise recording the time at which said lock is operated. It frequently happens that` an employee entrusted with the operation of the locks will operate the ordinary lock and leave the key of the recording lock with some unauthorized person with instructions to the latter to operate the recording lock ata given time. In'this connection it'should be remembered that the'authorized employee will seldom take the risk of leaving both locks open, and since he does not wishto operate the recording lock before the/proper time he will usually lock the ordinary l'ock. It is the principal object of this invention to provide means whereby such unauthorized operation of the locks is prevented.

lt is a further object of this invention to provide means whereby operation of the vordinary lock is rendered impossible until the recording lock has been operated.

A further object is theL provision of'means for accomplishing the aboveobjects which involves a. minimum change of stru'cture'in the locks, and which is inexpensivev and easily applied to present types of locks.

A further object is theA provision of simple interconnecting means between `the bolt of the recording lock and the ordinary lock whereby' accessfto said ordinary lock isi'cut oii' until said boltisv operated to locking position.

f Other objects'and advantages will in part be obvious, and in-part specifically pointed out in the specification.l v

To the attainments of the aforesaid objects and ends my invent-ion consists in the novel details of construction, and inthe combination, connection and arrangement of parts hereinafter more fully described andV then In the accompanying drawings, Figure lgis a front elevation ofva portion `of a doora'nd amb having a' recording lock and a primarylock and showing my inven Vtion attached thereto, partsv being broken away to disclose the underlying structure;

Fig. 2 is a view similar to Fig. 1 'but' with the locks indifferent operated positions;

Fig. 3 is a side view with parts broken away of the device shown in Fig. 1;

Fig; 4 is aperspective View of the operative connection between the locks;

F ig.' 5 isa view similar to Fig. 1 showing a modified structure of operative connection between the locks;

Fig. 6 is a View similar'to F ig.' 5 with thelocks in different operative positions;V

Fig. 7 is a side elevation, partly broken away of the, device shown in Fig. `5, and

Fig. 8 is a perspective View of the'bolt employed in the recording lock of Fig. 5.V

Referring to the drawings, there is shown A sleeve 20 'extendssubstantially througlr i the door and has a iange 21 at its front end resting againstvthe outer vfaceof ythe door and' a flange 22 preferably screw-threaded on its other end `within a` cavity 23 in the srl.'

rear face of the' door.l vIt willbe understood Y that the lsleeve isj'forced inwardly from the outer face. of the door and` the't1ange22 is then screw-threaded upon itsinner end to holdv the sleeve lipixed'in position.` A connect'-V ingmember 25 inthe formof a bellcrank arrangement has a shaft ,26' extending kth'rough'said sleeve and has formed, preferably integral therewith, an arm l2 7` on its ,outer end to operate over the outerl surface of the door, andfan arm' 28 on its inner end operatingin cavity 23 within the door. The

arm 28 is provided at its free end withV a pin 29 which extends'rearwardly'from larm `28 into a cam slot formed in the bolt of the recording lock. 'The said pin 29 may be provided with anv anti-friction roller 30.,

f The angle at which arms 2T and 28 are disposed relative to eachother, and the inclination of slot 35, may be 'varied lat. will to accomplish the desired functioni. e., to ro-' tate arm 27,'wh'en thev bolt 14 is operated to locking position, from a position directly over key-hole 36 of lock 10, (as in Fig. 1)to a position such that said key-hole is eX- posed (as in Fig. 2) and to restore they arm 27 to the position where it. covers key-hole 36 when the recording llock is opened. As

shown, the arms 27 and 28 are substantially at right angles, the arm 27 extending downwardly to cover key-hole 36. The cam slot is shown inclinedv downwardly to the right, so that as the lbolt is shot, the arm` 28 rides` upwardly to rotate member 25', and hence the arm. 27. An enclosing casing 39 for arm 27 may be lixed to the door by screws extending 'from the. rear of the door into threaded openings 38 in Ilugs fixed to said casing, the latter having an opening 40l op osite the key-hole of lock 10.

twill thus be apparent that an employee cannot lock primary lock 10, and entrust s lockingojf the recording lock to some unauthorized person, because the primary lock cannot be-operated until the secondary lock has First been operated.

. In Figs. 5 to 8 is shown a modilied struc- 1 ture for accomplishing the same functions as lower portion its ends.

the device shown in'Figs.4 l to 4. yThe same primary and secondary locks 1,0 and 11 may be employed and enclosed by a casing 39 secured to the door, and providedv at its with a circular opening 40 registering with the lieyhole 36. of said primar-y loclr l0. Beneath the cylinder of the recording lock a sleeve vextends completely through the door and'has flanges 46, 47 at A shaft 48 extends therethrough provided with pinions 49 and 5,()V at its ends.

vThe 'flange 47 andthe pinion 50 extend bek yondl the door into the space occupied b the bolt 14,. The latter is provided wit al cut-out portion 5,3 tofaccommodate said flange and'pinion while permitting operation of ther bolt. The connectingmember `'between the locks is inthe form of a U- shaped trame Aormember 55l working in guides 55a provid-ed on the casing 39', and having'a raclc` formedupo'n one otits ve tical members yand meshing with pinion 49. VThe lower endo said frame' or member, `in the raisedV position thereof, covers l the v'key-hole, 36 of the'primary lock. The

till

said cut-'out portion 53 has the upperhorizont'al limiting wall thereof provided with aiackv() which meshesy with pinion-50.V It i's apparent that when bolt 14 isshot, the pinions 50 and 49 will be rotated to lower the trame and uncover the ke'yfhole 36, vand that when bolt 14 is retracted the keyhole 36`will bev again covered up.

, vvThe above description illustrates the princip'les embodied in my invention, but it will be understood that various changes :and

.modifications may be resorted to within the scope of my invention as defined'inthe anneXed claims. v

Havin thus described myy saidinvention,
