Application led May 6,

To all whom t may concern:

Be it known that l, SOLOMON Wisin, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Locks, of which the following is a Jfull, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specilication.

My invention relates to key operated locks, having tumblers, and more particularly to that type of locks wherein one set of tumblers is brought into line by another set, or by a suitable key, thereby forming a line of cleavage for the opening of the locked members that carry said tumblers.

lt has as its object the provision of a lock which is operated by a double set of concentric plungers and by such means to provide a lock of great strength and safety and at the same time, one which is simple to manufacture and assemble, and hence quite inexpensive.

My objects and other advantages to be noted ll accomplish bythat certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings, y

Figure 1 is a sectional view taken centrally through a padlock illustrating my invention and vshowingthe lock closed..

Fig. 2 is a like view of Fig. 1 showing the lock after it has been released.

Fig. 3 is a perspective view of the various springs as employed in connection with the lock shown in Figs. 1 and 2.

Fig. 4L is a side elevation of the key for the lock in Figs. 1 and 2.

Fig. 5 is anedgewise elevation of another form of lock.

Fig. 6 is a cross section of the said other form of lock, showing same in closed position.

Fig. 7 is a like view to lock released.

The two` locks shown in the drawings have been selected by me as simple means of illustrating the principle involved in my invention, and not at all as indicating any limitations in the application of my invention to locks in general,

Fig. 5 showing the Specification of Letters Patent.

Patented' Sept. 6, 1Q21.

1920. Serial No. 379,386.

The lock shown in Figs. 1 and 2 comprises a body portion 1 having a cylindrical openmg 2 for the operating plungers or tubes, and a socket 3 for the shackle, this lock bemg a padlock. The cylindrical opening opens inwardly of the body, toward an opening l 1n which slides the block 5. The block 5 carries the swiveled shackle 6, which when the block is in locked position will be engaged in the socket 3, and when the block is moved along in the opening` Al, will be free of the socket, so as to permit removal of the padlock from whatever device is in engagement therewith.

'llhere will be a casing around the lock, as at 7 inclosing the slideway for the block, and the cylindrical hole in the lock body will terminate outwardlyin a slot 8, through which the key will be inserted. The block has a cylindrical passage-way 9 therein for a series of tubular plungers, as in the case of the body, the parts being so arranged that the tubular plungers in the block will be projected into the cylindrical bore in the body, when the padlock is closed.

The tubular concentric plunger-s which form the basis of my invention, independent of the'i'orm of mechanism in which they are used, are shown in both illustrations as being four in number. Thus the locking plungers arev shown at 10, 11, 12 and 13, said plungers being mounted one inside oi the other, so as to form, preferably, a snug sliding fit. The inner plunger need not be tubular, as it forms the core of the plunger assembly. v

With each set of Vlocking plungers, there are furnished a set of springs, likewise concentric, as shown at 10a, 11, 12a andk 13, running from a wide to a narrow diameter.

As is evident the absolute iit into each other of the tubes or concentric plungers is not necessary, and the assembly of them into the lock is very sim-ple. They are merely set together the one inside of the others and the springs likewise assembled. The springs are then dropped into the socket oi the movable portion of the lock, and the plunger assembly dropped in after them. K'

The releasing or alining plungers are like the locking plungers concentrically mounted, and except for the inner one are of tubular form, as shown at 14, 15, 16 and 17, these plungers fit snugly and slidably, although the exact dimension is not essential, and correspond in size to the locking plungers. They are easily assembled and are merely dropped in place in the bore of the body of the lock.

The result of the structure now described is that when the block carrying the locking plungers is moved to a position which permits its spring pressed plungers to move into the bore of the body of the lock, they will at once be projected therein, and prevent further movement of the block, until they each one move out of engagement with the said bore.

To accomplish this unlocking movement, a key is provided having steps 14a, 15a, 16a and 17a, said steps being formed by preference at each side of the axis of the key, as Shown. There is also another stopping step 18a to limit the inward motion of the key.

The key when inserted in the slot 8 will contact with the four plungers 14, 15, 16 and 17 and press them inwardly, andthe plungers of the two series are so proportioned as to length, that when the key has been pressed home in the slot, the releasing plungers will have depressed the locking plungers, so that they are all pressed out from the bore of the body of the lock, and a line of cleavage formed between theltwo sets of plungers at the meeting line of the block and its slideway.

Nothing has been stated as to the definite length of the plungers of the two series, since this may be as desired. I prefer, however, that they be of varying relative sizes, dependent upon the nature of the key that is to be employed.

As is evident the variety of locks may be extremely wide, whenv formed according to the concentric plunger principle which 1 have above described, since the length of each plunger may be varied fractional parts of an inch, and each change of any plunger will vary the operation of the lock and require a different key. Thus in a lock of the character described having eight plungers in all, there Vmay be a variation, within quite wide limits of any one of the eight, which will demand a different shape of key and comprise a different lock which will open with no other key.

As another form of Vlock embodying the concentric plunger device, I have shown a Vrevolving lock structure (Figs. 5, 6 and 7). In thisvstructure the core 18 of the lock is held stationary in the casing 19, as is the plate 20, which in connection with the casing formsthe retaining socketA for the locking bar.`

The revolving piece 21 carries a locking bar `or finger 22 and revolves around the central core, inside of the casing. The piece 21 has a cylindrical hole therein which carkey is to be rocked, to swing the revolving Y piece and its finger 22 into unlocking position. 1

As heretofore stated, the above two embodiments of my invention are illustrative,

and I do notvdesire thatmy claims that follow be limited in construction because of my failure to describe other structures likewise illustrating the principle of my invention. Having thuadescribed ymy invention, what 1 claim as new and desire to secure by Letters Patent, is
