RAnLocK.

To all whom t may concern.'y y

Be it known that I, FRANK SOLEY, a citizen of the United States, residing in Philadel# member which effects the locking of the notched nose of the shackle is operated by a tumbler of the lock, it will oppose a rigid resistance to outward pull upon the notched nose of the shackle.

In the accompanying drawing ;-4Figure 1 coverlate or front half .of the casing remove the lock being shown in a closed posi-` tion. Fig. 2 is a similar view showing the lock in the open position; Fig. 3 is a transverse section of the lock on the line (1f-a, Fig.

1, and Fig. 4 is a pers ective view of thek Working parts of the loc i detached from the casing and separated one from another.- n

The lock has a two-part casing 1 and 2, the back shell having a flanged edge which meets the front shell when said shells are secured together by riveting the opposite ends of the various transverse pivot pins or studs with which the lock is provided, and which project through applropriate openings formed inV the two shells, t e flange being cutaway for the entrance of the nose portion of the shackle 3 and also for the reception ofthe enlarged butt or hub portion 4 of the same.

The working parts of the lock comprise a flocking-plate 5, two tumblers 6 and 7*, aseries of wards or stationary washers 8, 9 and 1,0,1and a s ring 11. The shackle is hung to a pivot pin 12 and has a notched nose 13, a projecting heel 14 and a toe 15 adjacent thereto. The lockingplate 5 is guided by the shackle stop plate 16 Y so as to be free to slide transversely across the upper portion of the chamber within the lock casing, and it is held in its plro er position against the back-plate 1 of t e ook casing by means of a stud or lu 17 projectin r from the front face of the loc ing-plate and Specification of Letters Patent.

bearing against the inner face of the front` plate 2 ofthe lock casing, asshown in Fig. 3.

The locking-'plate 5 has in its lower edge a notch 19 for the reception of the upper endk of a projectingarm 20 on the rear tumbler 6, and both saidrear tumbler and the tumbler 7 engage with the heel14 ofthe shackle when the lock is closed, as shown in Fig. 1, a lug 21 on the locking-plate 5 at the same timeV engaging with the notched nose of the shackle.

The tumblers 6 and 7.are pivoted upon aV pin 22 and are acted upon by the bits of the key which is inserted ina slotted and rotatable key hub 23 journaled in `the opposite shells. of the casing.`

The wards or i'iXed washers 8, 9 and 1() engage the pin 22 and also'engage another pin 24 in the casing, so as to be held against movement therein, these lwards or iixed washers requiring that the key shall be notched in a certain way for their reception, andthe rearmost ward 8 also having a shoulder 25 for engagement with the bit of the key, in order to limit the turning movement of the same. j

The spring l] engages a transverse pin 26 in the casing, and has twoarms, the lower bearingupon the backs of the tumblers 6 and 7 and lserving to retain them in the normal position shown in Fig. 1, while the up er arm bears upon the toe 15 of the shack e, and serves to swing the latter intor the open position where it is free from the influence of the locking devices.

When the lock is closed, the parts are as shown-in Fig. 1, but the action of the key upon the tumblers 6 and 7 serves to retract A the same until they are withdrawn from engagement with the heel of the shackle and at the same time causes an inward sliding movement of the locking-plate 5, so as to withdraw its lug 21 from engagement with the notched nose 13 of the shackle, whereupon the latter is swung open by the action blers yand the parts assume their? normal or locking position.

By the employment, in connection with the notched nose of the shackle, of a sliding locking-plate engaging its operating tumbler in the manner described, a rigid resistance is opposed to outward pull upon the shackle,

the p1ate-5 .being .incapable of. yielding in that direction. l

If desired, the tumbler' only may bei used, or, if both tumblers 6 and 7 are employed, the tumblerl may engage only with -the lockingplate 5, the tumbler: 7K. engaging the heel .of the shackles I claimz.
