IMPROVEMENT. I,N TIME-LOCKS.

Specification forming part of Letters Patent No. 170,558 dated November 30, 1875; applicatioufiled August 24, 1875.

To'all whom it may concern:

Be it known that I, PATRIoK BRIEN HEN: NESSY, of the city of Hamilton, in the county of -Went-worth, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Safe Time- Lo'cks and I do hereby declare that the following is a full, clear, and exact description of the construction andoperation of the same, reference being had to the accompanying drawings forming a part of this specification.

Figure 1, Sheet 1, represents the inside of a safe-door with my lock affixed to the same. Fig. 2 is a side or edge view of the door. Fig. 3 is the lock detached with the cover or faceplate removed. Fig. 4 is an end view of the same. Fig. 5 is a top view with a portion broken away. Fig. 6 is a vertical section at the line as w:

A, Fig. 1, represents my lock secured to the inside of a safe-door, S, by means of four screws, U U U U. It can be easily fastened to the door of any safe or vault without removing the looks upon them. Inside of the lock, and a little to one side, is secured a time-movement, B. Any movement which will keep correct time will answer. O is a dial affixed to a small shaft, to. lt'has cut on its face a series of figures, marking hours. Any number can be marked on it up'to one hundred. It is provided with an index-hand, D, the purpose of which will be shown hereafter. E is a connecting-lever, provided with a horizontal arm, g, and an upright arm, g, the said portion g being secured on a pin, f. Its extreme outer end is provided with a horizontal pin, 01, which is for droppinginto a notched wheel, as will be shown hereafter. It is also provided with a pin, 0, projecting horizontally from it, which drops into a notch, c, of a disk, b, which is affixed to .the shaft (1 alongside of .a gear time-wheel, F, on the same shaft. On the free end of said lever E is fastened a slotted guide, m, which is made to pass on each side of the frame of the timemovement, for the purpose of steadying the said lever. G is a wheel, having a plain outside edge, and has a notch cut in its outer circumference, for the purpose of allowing the pin 61 of the lever E to drop into it at a certain time, which has the effect of pushing back the lever to open the look at the set time. H is a lock-bolt, affixed to the pin J. Whenv the bolt .is up it isopposite the bolt-hole f in the end of the look, as shown in Figs. 3 and 4.. The safe or vault door is always looked when the bolt is in the horizontal position, as shown, and open when the said bolt drops. It is provided with an upward arm, I, on which the part 9 of the lever E operates to raise the bolt H when itis down. J is the pin affixed to the back of the lock upon which the bolt H revolves. K is a pendent pawl, affixed upon pin f. Its lower end is constructed with a catch, 1, which is made to hook under a projection, i of the cylindrical portion h of the bolt H for holding up the said bolt to its place opposite the bolt hole or opening f in the end of the lock. j is a small pin inserted in the vertical party of the lever E, the object of which is as follows: when the lever E is pushed back the said pin j presses against the pawl K and releases its catch 1" from the bolt H, when the said bolt drops down by its own weight, as shown in dotted lines in Fig. 3. L is a tongue, affixed to the sliding bar 'I of the safe-door bolt immediately opposite the boltholef in the end of the lock, and into which it enters (when the lock-bolt H drops in the position shown in dotted lines in Fig. 3) when the sliding bar T and bolts M are thrown back by means of a turn of the outside handle N. Z l l l are circular collars tightly surrounding the bolts M. Said collars are made to Work in slots cut into the fiat sliding bar '1, so that when the said bar is moved by the action of the outside handle the circular bolts M and and the tongue L move with it, and it will be observed that the said sliding bar with the bolts attached cannot be moved back to open the safe-door, as the tongue L will come in contact with the end of the locking bolt H, which completely blocks up the bolt-hole fiu the lock; the safe-door, therefore, cannot be opened until the time is up for which it was set. At that time a small pin, 0, of the lever E drops into the notch c of the small wheel or disk I), which allows the pin d at the end of the said lever to simultaneously drop into the notch c of the larger wheel G, which pushes the lever back and causes the pin j to strike against the pawl K, the backward movement of which releases its catch from the cylindrical portion of thelocking-bolt when: it (the boltH) dropsL TheboltsM can. thenall be thrown. back by a turn of the handle, as the tongue L can then enter unobstructed into the look through the opening f. O is a spring, affixed to the arm 9 of the lever E,andheld in place by the pin P. Its object is to push the said lever forward. 0 is a similar spring, attached to the. upper end of the pawl K and held in place by the of pushing the said pawl forward, so thatit may. alwayscatch and hold up the bolt H until released. by the lever E. Q is a shaft, upon. which the spring for motive power is fastened, whichis on the underside or behind the wheel G, and not necessarytoibe shown on thedrawing. A knob,Q,isfastened tothe outer end a of saidxsbaft Q by means of a small screw, for

the purpose. of convenientlyturning. and settingthe handD togany desiredhour. Itlisthe faceplate of the lock, secured toit by means of the two screwspp. I

Intheoperation of the device the firstthing to be done is to set the hand D, by means of ,thekuoh Q, to any hour hour marked; onthe dialqO at which. the door is required to be opened. This, of course, is done while the door is open. Theidoor is thenclosed and the boltsMare shotinto their reccssesby a turn of l the handleN. This actionalsowithdraws the tongue L from theiopeningf in the lock, and thebolt H rises and covers thelopening therebylocking the safe-door. The bolts M and tongue L cannot be moved back until the hour arrives that it was set to. When the set hourof opening arrives, the pin don the connectinglever E drops intoithenotch c of the wheel G, and forces thesaid lever back against the pawl K, which releases its hold of the locking-bolt H, and allowsthe end of said pin P, and it is for the purpose bolt to drop, as shown in, dotted lines, Fig. leaning the-openingf freefor the tongue L to enter when the outside handle is turned, thus a. allowing all the bolts M to be drawn back to open the door.

Thegear-wheels may-be p'laced in the most convenient position for operating the device.

I maynow mention, what should have been stated above,that s is a flat spring secured to the arm g of the lever E, and made to pass into a notch in the arm g of the same lever, for the .purposeiof assistingtopusn downward the outer end of the said lever E, so that the pin d will not fail to drop into the notch a of the wheel G, and also the pin 0 to drop into the notch c of thedisk b.

What I claim as. my inventiomand desire to. secure by Letters Patent, is-- a 1. In combination w'th. atime-movement,

the lever E, provided with pins (1 oj, armsg and g,yan.d guidem, hinged: on. the pin f and acted upon by springs O. and s, wheelsG and It); siubstantially as and for, the purpose specie a i i 2. In combination with] a time-movement, the-arrangementofthe wheelG, with. notchpc, and wheel b, with notch c, for [operatingthe lever E andpawl; K,substantially.asand for the purpose specified.
