The pin tumbler lock is a lock mechanism that uses pins of varying lengths to prevent the lock from opening without the correct key.Pin tumblers are most commonly employed in cylinder locks, but may also be found in tubular pin tumbler locks (also known as radial locks or ace locks). Designed for high-security applications, the upgraded physical attack resistances give the Series 65 a complete set of security features: key control, anti-manipulation, and anti-destruction. That is springs 36 and axial tumblers 38 are included in cylindrical tumbler passages 31 of the plug 30 and are arranged concentrically and radially spaced about axis 12. When reassembled the sidebar must be pointed down, wi… 7, the spindle is in its key-inserting and key withdrawing position. 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. Spindle 28 also includes pin tumblers 40.

Then the fixture and lock housing may be further processed before the locking mechanism is inserted or incorporated with the lock housing. In effect this interengagement between the drive pins and the sides of the notches constitutes a plurality of circumferentially spaced splines through which torque is applied to the spindle uniformly around its entire periphery and Without the need for a driving lug on the key entering a recess in the spindle as was the case in earlier locks of this general type. 9, the dome or cup-shaped protective collar has a plurality of lugs or tangs 50 on its peripheral edge, which are bent down over the inner face of the iiange 9' to hold the collar in place, but this assembly cannot be effected until after the spindle has been assembled with the casing. Axial/Tubular Lock. Passage 54 or groove 54 extends axially the axial dimension or length of plug 30. To define that proper rotational orientation between the lock and the key and to prevent insertion and/or withdrawal of the key except when the spindle is in any but the correct position a ball 33 is loosely seated in a hole 34 which extends radially through the annular wall 35 of the spindle head portion which surrounds the plug 31 and coacts therewith to define the annular keyway. The key that goes with these locks are cylindrical in shape. Withdraw the plug from the cylinder. Allen head set screws 20 close the rear ends of the wells and provide spring seats against which springs 21 react to yieldingly project the tumbler pins across the interface and into tumbler receiving pockets 22 drilled into `the head portion of the spindle from the shoulder 14. said front wall portion of the protective collar having a round hole of a diameter corresponding to the outside diameter of the annular keyway. FIG. In any event, upon full insertion of the key, all of the drive pins will be depressed the correct distance to align the abutting ends of all of the drive pins and their respective tumbler pins with the interface providing the key is properly bitted. 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. Hence unless displaced the ball 33 bridges across and blocks the keyway. As noted hereinbefore the rear ends of the tumbler wells 19 are closed by removable headless set screws 20. Such alignment then ensures that the opening or passage 66 is appropriately aligned with the opening or passage 54 in the plug 30. They are generally considered by the general public to be safer and more resistant to picking than standard locks. 1.

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. Thus, in this case, the collar not only overlies the radially outer surface of the casing ange but also has a front wall portion 48 to cover the front face of the casing and the adjacent portion of the spindle. 3. With such alignment the spindle will be freed for rotation. 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 ends of the axial tumblers are alignable along a transverse plane in response to a bitted key that axially moves and aligns tumblers along the transverse or shear plane between the plug and spindle, thereby permitting rotation of the spindle relative to the plug within the sleeve of the inner cylinder assembly. The pin tumbler lock of claim 4, wherein the well of the detent means is a cross bore extending diametrically through said central part of the spindle head portion. .

National Cabinet Lock, now known as CompX National, has designed and produced locks since 1903. These types of locks are used on elevators, computers, bicycles, coin-operated laundry machines and vending machines. The George patent, No. Ball detents releasably hold the key in its fully inserted position against the thrust of the tumbler springs thereon, and another ball detent prevents insertion and/or withdrawal of the key except when the spindle is in 4a predetermined position of rotation. There is disclosed and claimed in Kotov et al. FIG. ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNOR:CLIFF, WILLIAM H.;REEL/FRAME:009130/0407, Free format text: Our patented AXIAL Pin Tumbler mechanism offers superior key control and manipulation resistance. The detent means by which this advantage is gained consists of a pair of balls 42, smaller than the ball 33, one at each end of a cross bore 43 extending axially through the plug 31 near its front face. 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. 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. A further object of the invention is to provide an axial pin tumbler lock which allows cabinet makers to preassemble an outer cylinder housing, shifter and cam or bolt to the cabinet product and subsequently insert a locking mechanism or core into the housing during a final assembly or final manufacturing stage or in the field. Withdraw the plug from the cylinder. Disc tumbler locks are available at a lower cost and are used for more simple keying requirements. 3. 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. 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. 4a is a cross sectional view taken along the line 4a--4a in FIG. 8, the protective collar 47' is dome or cup-shaped to afford even greater protection. These kinds of locks, however, can be picke… The tumblers are removable from the rear end of the lock casing to enable yauthorized changing of the combination of the lock. Disassembly of the Biaxial is simplified compared to other sidebar-based locks because there are no additional finger pins used in the sidebar. 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. Door viewer Optical device fitted through a door to enable observation without opening the door. Accordingly, upon full insertion of a proper cylindrical tubular key 26 into the keyway, all of the pin tumblers can be brought to their positions freeing the spindle for rotation. Its front face is ilush with that of the casing and spindle and it has an inwardly directed flange which lies behind the flange 9 to be confined between it and a panel on which the lock is mounted. 1 is an exploded side view of the component parts comprising the lock of the invention; FIG. An axial pin tumbler lock with a removable core comprising, in combination: (a) a cylinder housing with a generally cylindrical throughbore defining an inside surface, a longitudinal axis, and at least one non-cylindrical surface on the inside surface, an annular slot in the inside surface defined by an inwardly extending, radial flange, said flange including at least one passage therethrough, said flange extending around the inside surface of said cylinder housing; and. 5 is a cross sectional view through FIGURE 2 on the plane of the line 5-5; FIG. 4 wherein a picking or core removal tool has been positioned to release the inner cylinder assembly or core; FIG. The inner cylinder assembly further includes the locking mechanism which comprises an outer sleeve, a plug or barrel within the sleeve, said plug including biased axial tumblers in tumbler passages, and a rotatable spindle with axially slidable tumblers mounted in axial passageways in the spindle. 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. 1; FIG. Hence, insertion of the key into the keyway is possible when the spindle is in its position in which the hole 34 aligns with the recess 36. To receive the spindle, the casing has a bore 12 which opens to the rear and a counterbore 13 which opens to the front end ofthe casing. the side of the plug 31 and the side of the bore 30. The axial pin tumbler lock such as the type generally described in U.S. Pat. 6 illustrates the next sequential step, namely the axial sliding movement of the inner cylinder assembly along the axis 12 for removal. For example, both the inner cylinder assembly and the housing 16 may include compatible or congruent flats or flat surfaces or other shaped surfaces which provide for the appropriate, non-rotatable alignment of the sleeve 26 relative to the housing 16. This manner of drivingly connecting the key with the spindle is also conducive to reduction in the width of the keyway a feature which is quite significant from the standpoint of increasing the security of the lock, since it minimizes the probability of defeat by means of la cylindrical tubular hole cutting saw. An end plug 30 is also slidably inserted in housing 16. A screw fastener 20 holds a cam or bolt 22 in communication with and fastened to a drive shifter 24 which is rotatably mounted in the housing 16. The lock 14 has an outer housing or cylinder 16 which may be externally threaded for cooperation with a fastener (not shown) for retention in a cabinet, drawer or the like. Axial rotation is a concept primarily used in pin-tumbler locks that requires locking components be properly raised and rotated in order to unlock the lock. In the detailed description which follows, reference will be made to the drawing comprised of the following figures: FIG. FIG. 6; and. The pin tumbler lock of claim 1, further characterized by a protective collar encircling the front end of the bored casing and having a front wall portion covering the front face of the casing and the adjacent part of the front face of the head portion of the spindle. Nothing but friction prevents rotation of the protective collar 47; hence if torque is applied to it in any Way, it simply turns without affecting the lock. During insertion of the key, the balls 42 are pushed into the cross bore to snap into holes 45 in the key when the key is fully inserted. The point 74 of the rod 72 can then engage against a chamfered surface 76 of the disc 32 and thereby move the disc 32 radially inward and transverse to the axis 12 against the biasing force of the spring 34 to release the disc 32 from the engagement with the flange 62. Yet a further object of the invention to provide for an axial pin tumbler lock which may be rekeyed in the factory or in the field. ` AXIAL PIN TUMBLER Loox Filed April 24, 1968 4 Sheets-Sheet 1 P.
