Application Februaryis, i933, serial'No. 656,609 l 7 claims. (c1. vo-'i'zy This invention relatesto improvements in locks and has for its principal object, the provision of a safe and secure lock mechanism designed to be opened by akey, but only by the one authorized to use such keyp A further object is to equip the lock with simple and unique means to forestall anytampering with'the mechanism, by unauthorized persons.
An additional object is to produce a lock that is exceedingly simple in construction, economical to manufacture, highly emcient in use, and which lock simulates the appearance oi an ordinary lock.
Other objects and advantages will be apparent duringthe course of the following description.
1 In the accompanying drawings froming a part of this specification 'and in which like numerals are employed to designate like parts throughout the same,

Fig. 12 is a view similar to Fig. 10, taken on the line 12-12 of Fig. 11 and showing the key actuation of the lock.
In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 desighates the barrel of a lock having alcylinder 6 capable ofrotating within the barrel. The cylinder has the customary'key-way 7 'and the customary push pins 8, 9, l1, 12 and 13. These push pins 8 to 13 inclusive are contacted by locking pins 14,.'16,"l7', 18 and 19,*r'espectively. These locking Vpins 14, 16, 17, 18 yand 194 are in turn pressed downwardly against the push pinsby springs 21, 22,'23,24'and 26,"respectively. The construction-thus far described is common in this type of lock.l Y f My improvementccnsists in placing about the cylinder 6, a vseries of peculiarlyiormedbands `27, 28, 29, 31 and 32. Referringnow to Figa, v7 and 8,r particularly, it will be noted that the ring 32 has a portion thereof out away Aso to form shoulders 33 and 34 (see Fig. 6). This ring 32 is pinned to the cylinder'as by a pin 36. Thering `29 is cut awayon opposite sides thereof so 'as' to 'form shoulders 37-upon one-side, which engage either the shoulders 33 and` 34 of the ringl 31. This 41.-I The ring 27 is cut so as to form shoulders 42;
The cutting of these rings is such as to leave a' space between the adjacent faces of the shoulders of -Y the adjacent rings. These spaces are best shownI at A and B (see Fig. 4)', also (see Fig. 3)
This-arrangement permits aslight rotaryr play between the various rings. Each ring is provided with an opening 43 through which the locking pins may pass (see Figs. 4 and 5).
The operation of my device is as follows:-
Assuming that a key is employed for actuating the lock, the key is inserted in the customary manner which will result in elevating the pusher pins 8, 9, 11, 12 and 13, thus lifting them to the position shown in Figs. 11 and 12, at which time the upper ends of all of the pusher pins will be extending vinto the openings 43 in the rings 27, 28, 29,31 and 32, respectively and will be flush with the outer surface of the rings. At this time the cylinder with the rings thereon may be rotated so as to actuate the bolt mechanism. Now assume that a person attempts to pick the lock, without employing a key. In picking a lock it is customary to place rotary tension on the cylinder and to then with a pick press upwardly on the bottom of each of the pusher pins. We will now assume that, as a matter of illustration, the person pushes upwardly upon the pin 13 and moves the locking pin 19 to the position of Fig. 5. The rotary tension PTNT ,V jo'FlFCE` The ringY 28 is likewise cut so as to formgshoulders39 and will now cause a binding action upon the remaining locking pins. The person now pushes up- Wardly upon the various pusher pins in accordf ance with standard practice. vAs soon as the pusher pin, for instance 12, pushes the locking pin 18 upwardly until it reaches the position of Fig. 12, then a slight movement will occur, which will oiset the pusherpin from thelockng pin. As a consequence thelocking vpin `will notbe raised anyfurther, nor will the pusher pin be raised further. As a result a person attempting to raise any one of the pusher pins will automatically cause the locking pin to be disengaged as far as movement is concerned, from its pusher pin with the result that thelock cannotibe, actuated without the use of aIA key.
It is to be understood that the form of my invention herewith shown :and described is to be taken as a preferred example of the same and that various changes relative to the material, size,shape #and arrangement-of parts may be vresorted tol Without departing from-:the spirit of the invention within the scope of the -subjoined claims.
.Having thus described my invention, I claim:-
