` Spccilieation foiniing part of Letters Patent No. 121,752, dated December 12, 167]; Reissue No. 6,787, dated v December 7, 1875; application [iled July 9, 1873.

.To all whom it may concern/ Be it known that I, STEPHEN WILLIAM HOLLEN, of Cincinnati, in the county of Ha1nilton and State of Ohio, have invented an Imrproved Combined Time Mechanism and Non- Chronometer Lock, of which the following is a specification.

My invention has for its object to combine a time mechanism with a nonchronometer lock, and effect a union between the two by a lever-connection and a moving dog or bar, in such a manner that said parts will dog or render inoperative the bolt of the non-chronometer lock, and render the same incapable of being unlocked until the time mechanism and its lever-connection has ceased its dogging action upon the bar or dog of the nonchronometer lock, and even then said lock remains locked only to be opened bythe author-4 ized person.

My invention consists in the combination of a time mechanism and a nou-chronometer lock, with a lever-connection, and a bar or dog, the latter and the said leverconnection being operated by the time mechanism, and

said lever being constructed and located to act on the bar or dog, to dog or render the bolt of said lock incapable of being unlocked, when locked, until the arrival ofthe appointed time, when the time mechanism .ceases its dogging action, and admits of the bolt being operated. The invention further consists of the combination ofa time mechanism and a nonchronometer lock, each arranged in its own casing with a lever-connection,operated by and extending from the time'mechanisni into the lcasing ofthe non-chronometer lock for holding 4a bar or dog, for dogging and preventing the bolt of said lock being unlocked, when looked, until a certain predeterminate hour. The invention further consists in combining with a non-chronometerlock atime mechanism, having a lever-connection, operated by said time mechanism for holding a dog or bar, for dogging the non-chronometer lock, with a mechanism for operating the lever-connection, to release the bolt for unlocking, and with a mechanism for automatically stopping the running action of the time movement when the bolt is so released.

bined time mechanism and non-chronometer lock, with the levencoiinection, and a dog or bar, for (logging the non-chronometer lock. Fig. 2 represents a portion of the time mechanism.

.In the drawing, A represents a non-chronometer lock, having a locking-bolt, B, and .C is a vertical sliding dog or bar, mounted in the back end of the lock in such manner that when the bolt is out the dog or bar can slide down behind it and prevent it from being drawn in or unlocked until the dog is raised. A spring. lr, is connected with the dog or bar, so as to throw the same up, except when held down, and prevent it from moving by its own weight. D represents a time mech-V anism, secured in position in proximity to the nn-chronometer lock, for the purpose of operating the dog or bar. This time mechanism is constructed in an ordinary manner, except that, as shown, the hour-hand is arranged so as to make one revolution in twenty-four hours/ instead of twelve, and that the dial is divided into twenty-four divisions to correspond. E

is 'a dial-plate, shown with twenty-four divisions, and is mounted on the shaft or sleeve of the hour-hand, while F is a circular disk, mounted on the hour-hand shaft behind the dial E, andv connected to said dial E by a sleeve, c, so that both Inust move together.

The dial E and disk are so mounted on the shaft that they can be turned around thereon,

while at the same time there is sufficient friction to carry them with the shaft as it revolves. The disk is provided with anotch, d, inl its edge, and upon the top of the disk therebears one end of a leverAconnection, G, which.' falls into the notch d, when the disk is turned, so las to bring it thereunder.

The lever-con` nection is pivoted7 and has its forward end arranged t-o bear on a pin on the side of the moving dog or bar of the lock, so that when lits end drops into the notch of the diskthe or bar into contact with the bolt, and prevents the same from being operated. H represents a rock-shaft, provided with an arm, y, against which a spring, e, bears, and with a crank, t, which bears underthe outer end of the leverconnection, so that when the end of the said lever-connection permits the spring a to move the dog away from the bolt the crank i will be allowed to turn, and the spring e to press the arm g against the balance-wheel of the clock, and stop the same; but when the lleverconnection falls to let the dog orbar dog the bolt of the non-chronometer lock, it also turns the crank i, and lifts the arm g from the v balance-wheel, so that the time mechanism can operate and set the disk Fin motion. rIhe divisions on the time-mechanism face, and on the dial E are numbered from l to 24, successively, and the notch in the disk is located immediately behind the last or twenty-fourth space on the small dial. As-the dial is turned on its shaft, so as to bring its dii'erent numbers under the hour-hand, the notch is, of course, brought into different relative positions to said hand, being at one time under,

or in line with, the hand, and at another time on the opposite side of the shaft therefrom. The relative positions of the hand and notch are not, however, changed by the running of the time mechanism, but only by taking hold yof the disk, and turning 4with the fingers.

` In order tov set the time mechanism, it is only necessary to turn the small dial until the number indicating the required hour is broughtL under the hour-hand-for example, if it is required to have the non-chronometer lock open at 9 a. m. of the next day, the dial is turned until the number 21 is brought under` the hand, as the required hour is the twenty-third one from noon of the previous-day, which is 'indicated by the number l-on the time-mech-V iiexible material, so that it can yield or bend when its end is raised by the disk, at a time when the bolt of the non-chronometer lock is back, so as to prevent the dog or bar from descending, forin such case said dog or bar will bear on top of the bolt, and prevent theend of the lever-connection from descending. To prevent the lever-connection from being kept in its bent or curved form during the whole time that the bolt of the non-ehronometer lock is back, by which the lever-connection would be liable to become permanently bent or set, the lower end of the dog or bar is beveled,and

the bolt of the aforesaid lock is provided with a notch or recess to receive the same, the dog or bar being thus allowed to descend almost as far as when it exerts dogging action on the bolt.

When the bolt moves forward the dog or barmoves out of the notch and dogs the bolt of the aforesaid non-chronometer lock.

From the foregoing it will be perceived that a time mechanismy is combined with a nonchronometer lock, a union between the two being effectedby a lever-connection which is constructed and located to dog or control the action of a bar or dog, to render the aforesaid non-chronometer lock incapable of being unlocked when locked.

Further, it will be perceived that under the invention the works of the time mechanism and the works of the non-chrometric lock are each arranged in its own casing, a union between the two being effected by a lever-connection operated by and extending from the time movement into and through the casing of the non-chronometer lock, by which means the works of the non-chronometer lock can be effectually dogged and prevented from being unlocked while the time mechanism is in running action.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, isi 1. The combination of a time mechanism and a non-chronometer lock with a lever-connection operated by the time movement, said lever-being constructed and located to hold a bar or dog for dogging the bolt of said lock and render it i'ncapaloe of being unlocked, when locked, until the arrival of the appointed time, when the time mechanism ceases its dogging action and admits ofthe bolt being operated.

2. The combination of a time mechanism and a non-chronometer lock, each arranged in i its own casing, with a lever-connection operated by and extending from the time movement and from or through its casing into the casing of the non-chronometer lock, for operrunning action of the time mechanism when the bolt is .so released.k

In witness whereof' I have hereunto set my hand this 3d day of July, 1873.
