Application filed August 5, 1926. Serial N0;'127,207L
This invention relates to time locks for safes, vaults, and the like, and more particularly relates to procuring protection against robbery during business hours. In an application filed by me March 10, 1924, Serial No. 698,056, for time. locks, I have disclosed and claimed a device associated with the ordinary time lock controlfor the bolt work of a safe or vault door,-
which may be adjusted to stop the runningv down of the time lock at a certain stage in its normal run prior to releasing stage, so
that the protected structure cannot be en tered until the device'has been adjusted to allow the time lock to resume running and the time lock has' completed the unfinished stage ofits normal run. 'The" device is ad justable from outside of theprotected structure; After the protected structure has once been opened, to restore the protection it has been necessary to rewind thetime lock mech-.
anism to a certain extent and to restore the interrupting device into active adjustment.
The principal object of the present invention is to improve on said protecting construetion and arrangement. l f
More particularly, the object of this invention is to provide a device of the character described, whereby daylight protection may be restored in a more simplemanner, and by.
merely making a simpleadjustment from the exterior. of the structure.
A further object of my invention is to prostructure, which, when rotated in onedirec tion, moves the slide bar of .the time lock a certain distance from releasing position, thus winding up the time lock movements a certain amount. This amount is preferablyabout forty minutes. The locking dog is pref-. erably spring actuated into active position with'respect to the bolt work, sothat, when this slide bar is retracted, the dogwill au-' tomatically assume position preventing the unlocking of the bolt Work.
it will stop and interrupt the running down .the' line 44 of. Fig. -1.
When the aforementioned cam is set 1n operatlve position,
of the time lock mechanism, in case it shall;

have been-set to run for a comparatively long 1 'periodoif time; The structure, in such event,
will remain locked indefinitely, and may not Y be entered until the cam has been adjustedto' release the slide bar of the time lock and the time elapsed for the time lock to finish the iremalnder of its unfinished-run to releasing *stage.
In order that a clearer; understanding 1 of this invention may be had, attention is hereby directed to the accompanying drawings, formrzf ing a part of this application and illustrat ing one tlon.
Referring to the drawings, is an ele I v.vation of acontrollable time lock mechanism-, 1v
possible embodiment otmy inven-g embodying. my invention associated with the bolt work of a protectedstructure, another work; Fig. 2-is a similar viewlof a portion of ,lockbeing also shown associated withthe bolt V 1 the mechanism, showing the parts in position releasing the bolt work Fig.3 isasectional view of the same, and is taken on the line 3-3 of Flgl 1; and Fig. 4 is a sectional =vi'ewofa detail of the construction, and "is taken 1on Similar reference characters-refer tosi mhl drawings. x Referrlng to the drawings, the time lock mechanlsm includes one or more usualclock' andpivoted levers 5,. which are movedby the clock movements, and which, when held againstmovement, stop the running of the movements 1, each having the usualrotatable setting'dials 2, pointers 3, winding stems '4,
clockwork. V ,The lower end .6 of each lever 5; engages ina slot or recess 7 formed in the 1 time lock slide bar 8; The slide ba r is slid-'- ablymounted onlpins 9'seeu'red to movement supporting block 9' disposed in slots 10 of the bar. At a certainstage in the running :down of. the-time locks, the levers 5 push against :the shoulders 11 of the'slide bar to =-move it toward releasing position. This bar 8 has a depending lug or'should'er 12, which on such'movement of the-bar pushes againstaw carrying aproj ecting portion 15, constituting.

pin contrary to releasing movement of the" slide bar 8. Member 14 may have an extension 19 opposite the dog 15 to balance the weight of the dog and .to act as a stop. When. 5 bowed, spring 18' is put under tension. and
pulls down on extension 19.
Slide bar 8 has another depending finger or projection 20.
A cam 21 is secured to the protected struc- 1o ture adjacent this finger for adjustment into 'andvout ofv dogging relation thereto. Preferably,'this cam is secured toa sleeve 22,
which islrotatable by means of a shaft 23,
whichengagesin thesleeve, and is supplied 15 wit-ha knob 24 disposed on the outside of the 20 locking-direction, opposingthe springsof the:clock.-mo'vements and winding the sameu Dial member has gear teeth .rneshingwith a gear 51 onz the windi'ngstem4, and carries a pin 52 which coacts with the heel 53 of- 2 lever -5,' so'that movement of bar 8 into locke ing'position winds the stem 4 and sets the dial 2 to thejdormant protection period,such as forty minutes; 1 The bolt 'workmay assume any one of 3 various-differentforms.- For instance, the bolt work may comprise a bar 26 slidably secured 'by' screws27 to the door of thestruccarried' onnone end of this bar. The inner in addition-to'the time look,"a combination-or other type'of lock is also desired, such lock 30 may be connected with some part of the 40, bolt-b'ar26i Forinstance, the bolt plate 31 of the lock 30 may be connected to a finger 32 of thebar .26.. 5
The operation'of the protecting'mechanism described above and the manner of its operaopened,the-slide bar, its cam, and the looking dog are inthe positions shown in Fig. 2. If it is desired to'put the structure under pro- 5 tection during business hours,-it is only necessary to turn the knob 24 sufliciently to rotate the cam 21 into :theposition shown in Fig.1..
This'rotationrof knob 24 moves the slide bar 8 acertainwdistance, and this movement in turn; byreason 0f the accompanying movementof the time locklevers 5, winds up the time lockz movements a certain amount. Preferably,- th1soperation sets the movements for a run of forty minutes or so. This moveoo ment of theslidebar 8 withdraws the projection from the pin 13, whereupon the abnormally rbowed spring :18 causes the locking-dogtorotate into active position, dogging the bolt work; r
" Now, inzthe course-of-thebusinessday, no
barhas. engaged the same. tureto be protected. The bolt28may be When the person may enter the protected structure until he has adjusted the knob 24 to withdraw the cam 21 from the finger 20 of the slide bar 8,
and then has waited the required forty 1 minutes, or so, which must be consumed before the time lock movements have moved the slide; bar 8 into releasing position. With such protection, it is believed that the structurelis safe against daylight burglars, since it is not believed thatburgula-rs would care to wait the required length of time before env trance maybe had to the protected structure With'a device of the character described,
compli'shed in the usual way by meansof the customary key applied to the winding posts:
after making: releasing adjustment of the knob 24. I
4. However, ifthe cam 21 'has'been ad- 1 justed into active position, the running down v of the time locks willbe interrupted and stopped at the comparatively short interval before releasing stage. Thus, the protected structure will remain locked indefinitely and f until the cam 21 is adjusted out of active position and the time locks have :run through the final stage. If such interruption is not desired, it is merely necessary to adjust :the cam21 out of active position before the slide From the above,it will be apparent that j the above construction and arrangement guards a protected structure securely against r daylight robbery, and after an opening of the structure, permits the restoration of this protection in a veryrsimple and easy manner,-
which does not-require the application of the windingkey tothe time lock movements.
As manylchanges could be made in the above construction and as many apparently widely different embodiments of this invention could be made without departingfrom the scope thereof,i t is intended thatallmatter contained in the above description or shown in the accompanying drawings shall be interpreted :as illustrative and not-in a limitingsense. What I claim is Y 1. The combination with astructure to be protected, of a locking dog, time lock'me'chanism including clockwork, a slide bar dominating movement of'the lockingdog, means 1 connecting the time lock mechanism and slide bar zwhereby the running down of the clock 7 work moves the slide bar in one direction to winding: up of "the clockwork.
2. The combination with a structure to be protected, of a locking dog, timelock-meclbment of the slide bar in the reverse direction winds up the clockwork, and means operable from the exterior of the structure to move said slide bar in the direction resulting in the winding up of the clockwork said means last mentioned constituting a device for preventing movement of the slide bar by said clockwork.
3. The combination with a structure to be protected, of time lock mechanism including clockwork, a slide bar, means connectingthe time lock mechanism and slide bar whereby the running down of the clockwork moves the slide bar in one direction and whereby movement of the slide bar in the reverse direction winds up the clockwork, means operable from the exterior of the structure to move said slide bar in the direction resulting in the winding up of the clockwork, a locking dog, means whereby movement of said slide bar by the clockwork moves said dog out of active position, and means whereby the looking dog is moved into active position when the slide bar is moved in the opposite direction.
4. The combination with the slide bar of a time lock mechanism, of a cam coacting with said slide bar, said cam being rotatable to retract said'slide bar and to assume'position preventing forward movement of the slide bar, and adjustable into position permitting forward movement of the slide bar, a locking dog, a spring urging said dog into active position, and a connection between the slide bar and the locking dog whereby movement of the slide bar in releasing direction moves the dog out of active position, said spring moving the dog into active position when the slide bar is retracted.
