TIME-LOCK FOR SAF'ES AND VAUL'IS.

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in time locks for safes and vaults.

In'certain sections of the country where hold-ups or robberies are liable to occur during the day time, it is desirable to safeguard the regular time mechanismof the lock,.by means that will actuate the time. lock unlocking lever at regular intervals, say once each hour, retain the said lever in unlocked position for a stated number of minutes and then look up again. It is evident that in robberies of this character, quickness is necessary, and with the safe door guarded and locked, say eleven-twelfths of the time during the day, the chances would be largely in favor of the attempt being made at a time.

when the door was locked. I

The object of this invention is toprovide, in addition to the customary timelocks which guard a safe door ordinarily from the close of one banking day to the opening of the following banking day, an improved device whereby whendesired the safe may be kept locked all the time except at certain de sired short intervals. The customary timelock taking care of the looking at night the improved supplementary device may then go into operation so that the safe or vault may be locked during the larger portion of the day; i. e. for instance, for the whole or every hour during the day except that there may be one, two, or more minutes out of each hour when' the safe can be opened, butif the safe should not be opened during that predetermined period then the timelock would automatically lock up again. This special supplementary device may be used either in connection with the customary timelockyand arranged to operate on the locking lever of said timolock, or it may be employed in connection with said ordinary timelock but have an independent locking mechanism of its own; or, it may be em-' Specification of Letters Patent.

ployed by itself separately on a door. In the deviceillustrated, both time mechanism actuate the same bolt unlocking lever which releases or sets free the bolt mechanism of the safe or vault, hence with thisparticular construction the main time mechanism is in operation during the period the supplemental time mechanism is set for operation, as well as during the period when the supplemental time mechanism is not in operation.

In the accompanying drawings, F igure. 1 is a view in plan of my improved lock. Fig.

1 represents one of the ordinary triple movement time locks, and 2 the unlocking lever, the latter being designed for connection with the bolt mechanism of the safe or vault door, and actuated by the time mecha-' nism 1 for releasing the bolt mechanism at a predetermined time in the usual and well known manner.

3 represents the supplementary mecha nism, which embodies the features of my in vention. This mechanism comprises a time mechanism consisting of two separate main springs inclosed in the casings 4 operating upon a spindle 5 carrying the dial 6, and two motors 7 which operate to actuate the unlocking lever 2, when tripped or released by the supplementary or day time mechanism. The-employment of two mainsprings in the time mechanism, and the same numher .in the motor is not essential, a plurality being employed simply asia. precautionary measure or safeguard, so that if one should fail the other or others would operate to release the bolt workmechanism at the proper time. The dial 6 makes one complete revolution in sixty minutes, and is marked off into sections, each section representing one minute and is also provided with threaded holes 6 located at five minute intervals.

8 are pins adapted to be screwed into the holes 6" in the dial and project below same, each pin being provided wit-h an enlarged head by which it may be grasped and manipulated. For the purposes of illustration opening in the plate 8 and. is normally held 'posite one of the releasing lever 15, rests by the spring 23.

this dial. is revolved by .cally located slots 24, into which the tooth l have shown the pins 8 located in two adja- 1 cent holes, thus representing an interval of l five minutes that elapses in the travel of the pins past a given point. 1

Pivotally secured to the rear face of the l outer plate 8* of the supplementary mechanism 8, is the lever 9 the lower end of i which is bent upwardly, passes through an 1n the path of the pins 8, by the spring 10. The opposite end of lever '9 is bent rearwardly toward the intermediateplate 11 ot the supplementary mechanism 3, and is provided with an enlarged end 12 having a cam slot 13 therein, in which rests the pin 14 carried by releasing lever 15. This lever 15 is pivoted to the rear face of the intermediate plate 11, and the pin 1 carried thereby at one end, passes through a hole in the intermediate plate and rests Within the cam slot in the lever 9. The opin contact with the pin 16 secured to the pawl 17, the latter being carried by a post 18 mounted at its outer end in the inter mediate plate 11, and at its rear end in the rear plate 19. The pawl is provided with a tooth 20 which moves in contact with a 21 driven by the two spring motors 7, and is normally held in contact with said flange Each motor 7 is provided with a key spindle 23 which passes through the intermediate plate 11 so as to be accessible from the front.

The flange 21, is provided with diametri- 20 of the pawl 17 drops. Then the tooth of the pawl is in either slot 24, the wheel carrying the flange is held at rest. lVhen however the pawl is pushed out of the slot by the releasing lever 15, the spring motors T are free to. rotate the wheel 21. and its shaft, 21 Secured to the latter in rear of the inner plate of the supplementary mechanism, is the disk 25 carrying a rcarwardly projecting pin 26 which latter engages one end of the lever 27 pivoted to the lock case, theopposite end of said lever resting in front of a lug 28 on the unlocking lever 2.

expiration of the five minutes, the

This unlocking lever is normally held in its locking position by a spring, hence when lever 27 is actuated as hereinafter described, it retracts lever 2 and holds it retracted tor a stated interval of time (five minutes in the construction as illustrated) and then releases it, thus permitting it to move to its projected position.

As shown in the drawings, the pins 8 in the dial are located in two adjacent holes, representing an interval of five minutes. As the supplementary or day time mechanism 3, the first pin 8 strikes the upturned end of lever 9 and turns same slightly. This movement of the lever 9 causes its cam slot i3 to move the pin 14 carried by releasing lever 15 thus forcing the latter against the pin 10 on pawl 17, and moving the tooth 20 ot the pawl 17 out of the slotit in flange 91. This disengagement ot't'he pawl and tlange, releases the motors 7 and permits the latter to actuate the shatt 21" which as before explained carries the slotted flange 21. As the first pin on dial 6 leaves the end of lever 9, the.

shaft, shifts lever 27 in a direction to retract the unlocking lever and holds same in its retracted position for the period of time represented by the distance between the pins 8. in the present instance, five minutes. At the second pin (5 coming in contact with lever 9. shifts the parts as above explained and again withdraws the tooth 20 of pawl 17 from the slot 24 in flange 21, thus permittin shaft 21".

to make another half revolution, thus restoring lever 27 to its original position and permitting the unlocking lever 2 to move back to its normal projected or locking position. This release of the bolt mechanism will occur once each hour, and for a period of five minutes at each release. The lever t) is also engaged by the pin 29 on lever 30 pivoted to the outer face of the. outer plate 8 of the supplementary mechanism 3. Th lever 30 is also spring actuated, but is designed to be moved by hand against the action of its spring so as to move lever 9 out of the path of the pins 8, a spring catch 31 being providedii'or holding lever depressed, thus disconnccting the supplementary mccl'ianism from the regular time lock 1. This condition of course is the one that will obtain at night, when it is not desired to have any periods when the safe can or will be unlocked. hen the supplementary mechanism is disconnected as above dcscribcd, the motor will be braked and restrained from acting, by the locking pin 32 carried by the spring arm 33, the latter being actuated by the lever 30, engaging lug 34 carried by said spring arm 33. This lug is located in the path of the lever 30 when the latter is moved to a position to carry lever 9 out of the path of the pins 8, and when engaged "by said lever, wlll be depressed "thereby and thus move the locking pin 32 into the path of a moving part of the motor and thus lock the latter againstmovement. By means of this lever 30, the attendant, can by slightly movingsame test his supplementary mechanism before putting it into use for. the day, which should of course bedone to see that everything is working properly, and by moving it back until it engages the spring catch, he disconnects the motors, thus leaving the bolt mechanism solely under the control of the main time lock, which is the condition the lock should be in after close of business for the day.

The main time lock mechanism may be set to unlock the lock at any predetermined time,an-d the supplemental time movement unlocks it and looks it at shorter fixed intervals during the time it is set to boreleased by the main time movement, hence .for another when the time arrives for the bolt' mechanism to be unlocked bythe main mechanism, the latter retracts the unlocking lever in the usual manner and holds it retracted until the movements are again wound up and set eriod.' It is ,evi ent that many slight changes might be resorted to in the relative air-- 'rangement of part shown and described without departing from the spirit and scope of the invention hence I would have it the exact construction and a rangement of parts shown and described, b t,
