To all whom it may concern: 3

Be it known that I, ARTHUR WILLIs BRODE, a citizen of the United States, residing at Downers Grove, in the countyof Du Page and State of Illinois, have invented a new and of to vary the combination and renew the members when broken or injured. I

Further objects and advantages of this invention will appearin the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure l is a view of a lock constructed in accordance with my invention. Fig. 2 is a central section of the same. Fig. 3 is a detached view of the core and shacklearm. Fig. 4 is a similar view of the shacklepin and head. Fig. 5 is a detached detail view of one of the tumblers. Fig. 6 is a similar view of one of the spacing-rings. Fig. 7 is a detail sectional view of the joint between the core-head and shackle-arm. Fig. 8 is a .vertical section of a modified form of the lock wherein a sliding shackle is employed. Fig. 9 is a transverse sectional View on the line 9 9 of Fig. 8. Fig. 10 is a transverse section on the line 10 10 of Fig. 8 to show the means for securing the uppermost spacing-rim g in place.

Similar numerals of reference indicate corresponding parts in all the figures of the drawlngs.

In the construction illustrated in Figs. 1 to 7, inclusive, 1 designates a core provided at one end with a preferably integral head 2, to which is pivoted a shackle-arm 3, said core being provided at one side witha groove or halfbearing 4 for the reception of the shackle-pin 5. This shackle-pin carries a head 6, constructed to interlock with the free end of the shackle-arm and secure the latter against swinging movement when the shackle-pin is in its normal or locked position. In'the construction illustrated the extremities of the head 6 and shackle-arm are rabbeted, and one is provided with a projection or stud 7 to fit in a depression or socket 8 in the other.

Mounted for rotary adjustment upon the core is a series of spaced tumblers 9, between which are interposed spacing-rings 10, said spacing-rings being preferably provided with exterior peripheral studs 11, while the tumblers are provided with finger-holes 12 to facilitate the adjustment thereof, said studs 11 serving as indicators by which the tumblers may be adjusted in manipulating the lock. The spacin g-rin gs are held from rotary movement upon the core by means of ears 13, projecting into a guide-groove 14 in the side of the coreopposite to the groove or shackle-pin bearing, and the terminal spacing-ring adjacent to the free end of the shackle-arm is held from axial displacement by means of a removable pin 15, preferably threaded into a suitable opening in the core.

Both tumblers and spacing-rings are provided with notches, respectively numbered 16 and 17, of which the former are permanently in registration with the groove or shackle-pin bearing, while the latter are adapted to be arranged either in or out of registration, as it is desired to release or look the shackle-pin, said shackle-pin being provided with notches 18, adapted to be arranged in the planes, re- 1 spectively, of the tumblers for engagement by the inner peripheries thereofwhen the notches of the tumblers are out of registration with the shackle-pin bearing.

An axial or longitudinal movement of the shackle-pin is necessary in order to disengage the interlocking extremities ofthe shackle- .arm and the head of the shackle-p'imbut it PATENT OFFICE.

ulating the lock and make it practically impossible for the same to be operated when the combination is unknown, I provide the tumblers with one or more false notches 20, which are not extended wholly through the tumblers, but consist simply of depressions or indentations which are adapted, when arranged in the plane of the shackle-pin, to allow a slight axial movement thereof, but which are of insufficient depth to allow disengagement of the shackle-arm.

As a further means of preventing tampering with the lock I preferably employ a pivotpin 21 at the joint between the shackle-arm and the core-head, which is threaded into place and is then swaged terminally, as shown in Fig. 7. The threads prevent the pin from being displaced axially by striking the extremity thereof.

In the construction illustrated in Figs. 8 to 10,.inclusive, the same relative arrangement of core 1, having a head 2, shackle-pin 5, tumblers 9, and spacing-rings 10 is employed as above described. The shackle-loop 22 is extended from the extremity of the shackle-pin and preferably terminates in a stud 23, which fits in an auxiliary socket near the opposite side of the core. In this form of the improved look I also employ a cap-plate 24, and as it is necessary to turn the shacklehaving a shackle-pin bearing, and a shacklepin provided with transverse notches, of a plurality i. of alternately disposed rotatable tumblers and fixed spacing-rings, the tumblers being reversible and provided with notches to register with said bearing and also pin in order to swing the shackle-loop in the act of disengaging the latter from any object I employ a stop 15 for engaging a shoulder 25 on the shackle-pin. This shoulder extends entirely around the pin, as indicated in Fig. 8. Furthermore, in this modified construction of look I employ a securing-pin 26, whichextends transversely through a suitable opening in the core and terminally engages inrings, said securing-pin being disposed to engage the spacing-ring contiguous to and below the uppermost tumbler.

From the above description it will be seen that the false notches which are arranged in the tumblers are disposed in both sides thereof, and that otherwise the tumblers are made symmetrical, whereby they are reversible to change the combination, the projecting points or markers upon the exterior surfaces of the spacing-rings being preferably arranged in alinement when the parts ofthe lock are assembled to serve as guides for the fingers of the operator, whereby the lock may be manipulated in darkness. Furthermore, the projections on the spacing-rings maybe arranged in any desired relative positions, those in the drawings being shown in pairs at opposite sides of the rings.

The advantage of the plurality of studs on the spacing-rin gs resides in the fact thatthey serve to indicate to the operator the proper positions of the contiguous tumblers, said tumblers being interchangeable, and hence requiring different studs to indicate their positions according to the relative arrangement of said tumblers.

respectively with means for engaging the shackle-pin, and also with projecting exterior finger-holds, and the spacing-rings being pro- ,vided with a plurality of spaced projecting I studs forming indicating points or markers for the contiguous tumblers, substantially as specified.

2. In a lock, the combination with a core having a shackle-pin bearing, and a shacklepin provided with transverse notches, of a plurality of alternately arranged tumblers Y and spacin g-rin gs having exterior projections for alinement, said tumblers being reversible to change the combination and having means to engage the shackle-pin, substantially as j specified.

3. In a lock, the combination w1th a core provided in both side surfaces with false 5 notches or depressions of less depth than the j tumblers, substantially as specified.

weirdly-extending ears 27 on the spacinghavinga shackle-pin bearing, and alternatelyarranged tumblers and spacing-rings mount- 4. In a lock, the combination with a core ed upon the core, said tumblers being provided with notches registering with said bearing, of a shackle-pin provided with transverse notches for engagement by the tumblers, a

securing-pin arranged in the core contiguous to one of the terminal spacing-rings to hold .the latter in place, and a shoulder on the shackle-pin in the path of which the extremity of said securing-pin is arranged, to limit the axial movement of the shackle-pin, substantially as specified.

5. In a lock, the combination of a core provided with an integral head 2 and having a shackle-pin bearing parallel with its axis, rotatable tumblers fitted upon the core and provided with notches to register with said shackle-pin bearing, a shackle-pin fitted for axial movement in said bearing and provided at the opposite end from said core-head 2 with a shackle-pin head 6, said heads being extended laterally in a common direction from the core, means for limiting the axial movement of the shackle-pin, and a shackle-arm pivotally mounted upon the core-head and having an interlocking connection with the shackle-pin head, adapted to be engaged and disengaged by the axial movement of the shackle-pin, substantially as specified.

6. In a lock, the combination of a core propin is extended, and to be conoealedthereby when the shackle-pin is in its normal position, and a shackle-arm pivotally mounted upon the core-head and having an interlocking connection with the shackle-pin head, adapted to be engaged and disengaged by the axial movement of the shackle-pin, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed mysignature in the presence of two witnesses.
