Obviously, of course, the entry of the balls 42 into the holes 45 does not prevent manual withdrawal of the key. and wherein there is a ball at each end of said cross bore and the spring is confined between the two balls. 6 is a side cross-sectional view similar to FIG. An annular circular keyway Z5 in the head portion of the spindle opens to the front face of the spindle and communicates at its bottom with all of the tumbler receiving pockets 22. 3, 509 748 Dated May 5 1970 Inventor(s) P .M Tra incr It is certified that error appears in the above-identified patent and that said Letters Patent are hereby corrected as shown below: Column 2, lines 4 and 5 should read Figure l is a longitudinal sectional view through a lock embodying this SIGNED AND SENER Aue 251970 (SEAL) Attest: mmm-m3 mw: x. m.

Insertion of the proper key 10 into the lock 14 to properly move and align tumblers so as to permit rotation of the lock core and operation of the lock 14 between the locked and unlocked position also causes the cam 22 and shifter 24 to be rotated so as to effect the appropriate locking operation by the lock 14. An annular keyway in the head portion of the spindle receives a tubular key by which the tumblers are moved to unlocking positions freeing the spindle for rotation. All the features of a standard pin-tumbler lock are still there, just configured in a circular pattern rather than inline as standard pin-tumbler lock is. In this position, the hole 34 aligns with a recess 36 in the wall of the bore 30 into which the ball may be pushed. 1. 5 illustrates the position of the pick 70 as inserted into the lock 14 so as to engage the chamfered surface 76 and effect radial or axially transverse, unlocking movement of the disc 32. 6 illustrates the next sequential step, namely the axial sliding movement of the inner cylinder assembly along the axis 12 for removal. said ball being of a diameter greater than the distance between the wall of the counterbore in the casing and the surface of the central part of the spindle head portion which defines the inner wall of the annular keyway. Axial pin tumbler locks are useful, particularly for cabinet drawers and the like. Another object of this invention is to provide a lock of the type set forth, in whic-h the combination can be quickly and easily changed. The cross bore 43 is large enough to accept the balls 42 which, however, are yieldingly urged out of the bore by a spring 44 confined between the two balls. Although the lock can be employed in different ways, and for different purposes, it is admirably suited to locking drawers or doors in their closed positions, in which event the body or casing 5 passes through a hole in a panel 8 and is fixed to the panel by clamping the portion of the panel immediately adjacent to the hole, between a fiange 9 on the front end of the casing and a nut 10 threaded on the casing. The shifter 24 includes a slot 44 which receives a tab 46 projecting radially inward from the inside throughbore surface 64 of the housing 16 to retain the shifter 24 in place within the housing 16. Tutorial Video showing how to deal with security pins and other advanced protection mechanisms in Pin Tumbler locks. This invention relates to pin tumbler locks and refers particularly to such locks in which the tumblers are circumferentially spaced around a circle concentric to the axis of the lock, to be moved to unlocked positions by a cylindrically tubular key inserted into an annular keyway. Removability is effected by means of a pick or probe 70 which engages the disc 32 moving it against the biasing force of spring 34 to release the inner cylinder assembly or core from the housing 16. In review, the lock 14 includes a removable inner cylinder assembly comprised of the sleeve 26, spindle 28, plug 30, disc 32 and spring 34 as described above. A freely rotatable protective collar on the front end of the lock guards against the application of torsion on the spindle except by a proper key. A transverse disc 32 biased by a spring 34 is mounted on plug 30. 2. The lock includes a cylinder or housing with a generally cylindrical throughbore adapted to receive an inner cylinder assembly which includes an axial pin locking mechanism. 4 is a cross sectional view through FIGURE 1 on the plane of the line 4 4; FIG. 5. UNITED STATES PATENT OFFICE CERTIFICATE OF CORRECTION Patent No. FIG. When these dots are opposite one another, as shown in FIG. The George patent, No. Door Closer A device for closing a door or gate automatically after opening. As the key is inserted, the front ends of the drive pins either enter these notches to be engaged by the bottoms of the notches, or are engaged by an unnotched edge portion of the key. The inner cylinder assembly may thus be removed and replaced with a cylinder assembly having a different set of tumblers and thus a different combination for actuation by a different key.

Axial/Tubular Lock Tubular pin tumbler locks, also known as Ace locks, circle pin locks and radial locks, is a pin and tumbler lock with circularly arranged pins. A removable core, axial pin tumbler lock includes an inner cylinder assembly which is retained within a housing for the lock by means of a spring biased disc which may be decoupled from the housing by means of insertion of a pick through a passageway defined in the inner cylinder assembly when the components parts of the assembly are appropriately aligned. and a spring in said well yieldingly urging the ball from the mouth of the well and against the outer wall of the annular keyway.
