The head P of hinge-pin P is of such width as to lap the rims of recesses a b, and when the reduced end P is riveted over to secure the hinge-pin P in place it is riveted over a washer P, which also laps the rims of said recesses. The head P and washer P are so extended over said rims as to relieve the backs of recesses 64 Z) from undue pressure, whereby they might be forced inward and compress spring c, interfering with the action thereof.

For the purposes of this specification the end of the lock-case in which the key is inserted is called the front and that in which the swinging end of the detachable arm of the shackle is locked the rear or back, and the device in the lock-case through which the key actuates the locking-bolt is called the key-head. When engaged by the key, this keyhead practically becomes a portion thereof, fulfilling the functions of a bit on the key.

011 the outside of the swinging end of arm A is a tangential tubular lock-ease D, having on the top thereof a radial tubular boltcaseE, located near the rear end of said lockcase. From beneath and somewhat forward of the center of the bolt-case the hereof the lock-case is of reduced diameter to its rear end, so as to form a segmental shoulder (Z in the lower part of said lock-case from the point of intersection therewith of the bolt-case on one side to the point of intersection thereof on the other side.

In the lock-case is a revoluble key-head F, comprising a segment F of a tube, closed at the front end by an annular plate F of the diameter of the interior of the lock-case and having therein two perforations f, adapted to receive the prongs K of the key. Normally the segment F is turned with its open side toward the mouth of bolt-case E, and at all times its rear end, which is open, bears against shoulder d.

A locking-bolt G plays vertically in boltcase E, and has its lower or lockin g end bifurcated, as shown in Figs. 16 and 17, the slot 9, separating the jaws, being of sulficient width to receive therein bar 6, extending across the bottom of bolt-case E, whereby the bolt is prevented from turning in its case. In their normal position the jaws of bolt G project below the bottom of bolt-case E and extend into lock-case D, the rear jaw g engaging a notch a in the reduced end Nof arm B. The outer edge of the bottom of jaw y of said bolt G is beveled, as shown at 1 Fig. 17, and is adapted to be engaged by the beveled end of head N of the reduced end N of shacklearm B, so that head N may raise bolt G and pass beneath the same when pressed into the rear end of lock-case I).

The front jaw, g, of bolt G extends down into the side opening, f, of key-head F, one vertical edge of said jaw being beveled perpendicular to slot g, as shown at 9*, Figs. 16 and 17. The jaws of bolt G are held in engagement with notch n and the opening in key-head F by a coiled spring S, located in bolt'case E and having one end bearing on the outer end of the bolt and the other end on a closing-plate E, resting on a shoulder c in said case, bcingheld down by rivetingovcr the outer edge e of said case, as illustrated in Figs. 22 and 23.

It will be observed that plate I of the keyhead is of the full diameter of the interior of the lock case, so as to prevent the introduction of any instrument by which the lockingbolt could be disengaged from the swinging end of the shackle-arm it looks in the case.

Between its front end and the plate F of key-head F a number of plates are located in the lock-case. One or more of these plates 11, as may be desirable, are ward-plates and each has on its lower edge a stud 71, adapted to engage a longitudinal slot (1 in the bottom of the lock-case. Each ward-plate has therein a central perforation 7t, with oppositelylocated wings 7L2, as is usual, and in the key K are oppositelydocated notches K adapted to engage the rims of perforations h as the key is revolved in the lock-case. Between the ward-plates and between said plates and the front of key-head F and the front of the lock-ease are closely packed thin spacingplates M, the openings m. in which are so large as to permit the key to turn freely therein. All these plates are held in place by a closing-plate D having a central keyhole (Z and a stud d, engaging slot (1, plate D being secured by riveting over the outer edge of the lock-case, as seen in Figs. 11 and 12.

In operating the key is inserted in the lockcase with the prongs K thereof engaging the perforations j" of the end plate of key-head F. The key is then turned until the lip f 2 of the longitudinal opening of said key-head engages beveled edge 9 of jaw q and raises bolt G until jaw g is disengaged from notch a of shackle-arm B, when that arm is automatically disengaged from the lock-case by the tension of spring 0. The key, afterbeing turned back to restore key-head F to its normal position, is then withdrawn from the lockcase.

In Fig. llv} is shown a modified form of keyhead. The perforationsf are omitted in this head, and instead thereof there is a diametrical rib f formed on the outer face of front plate F adapted to fillthe space between and afford a bearin g for pron K of the key whereby the key-head is revolved.

An unusual number of changes in these locks can be made with one or more wardplates by changing their relative locations by shifting the positions of any number of spacing-rin gs to the front or back of said plates. By this means a large number of locks of this pattern can be made in which no two locks can be opened with the samekey. The number of these changes can be increased by altering the construction of the keys. The lock herein described is opened by the key K (illustrated in Fig. 18 but instead of locating the notches K opposite each other they may be placed alternately on opposite sides of the key and extended into the center thereof, as shown in Fig. 19. A- further increase can be made in the number of such changes by varying the length of segment F of key-head F, as illustrated in Fig. 15, where two sizes of such segment are shown, though, as easily understood, that number may be increased.

The adaptability of the lock to such numerous changes for the key makes it particularly valuable, as it proportionablyincreases the safety of the look.

I do not limit myself to any particular construction of the locking-bolt and the key-head, or to the form and arrangement of the case containing the same; neither do I restrict myself to the details of construction of the other parts of the lock herein shown and described, as it is obvious that numerous changes may be made therein without departing from the spirit and scope of my invention.

My invention involves a radical departure in the construction and principle of operation of lock mechanism, the invention consistin g, broadly, in a shackle divided into sections hinged together at one end, a-case carryin g a locking-bolt,and a case through which the key passes to actuate said bolt, the said two cases being formed together on the free end of one of said shackle-sections and at an angle the one with the other, and a tongue on the free end of the other shackle-section and constructed to be locked in one of said cases.
