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. 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. The flange 62 includes an axial passageway or opening 66 which is aligned with a passageway 54 on the outside surface of the plug 30. A C-washer 17 snapped into a groove 18 in the spindle, and bearing against the rear face of the casing, holds the spindle in place with its shoulder 15 abutting the bottom 14 of the counterbore to define the interface, which is depicted in FIGURES 1 and 2 by the line IF-IF. The plug 30 includes a plurality of springs 36 and tumblers 38. Remove the camor C-clip. 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. 4 is a cross sectional view through FIGURE 1 on the plane of the line 4 4; FIG. said front wall portion of the protective collar having a round hole of a diameter corresponding to the outside diameter of the annular keyway. In a pin tumbler lock of the type wherein la spindle rotatably received in a bored casing having front and rear ends is secured against unauthorized rotation, by a plurality of spring biased tumbler pins slidably mounted in tumbler wells in the casing for endwise movement parallel to the yaxis of the lock to and fromspring maintained locking positions extending across an interface between contiguous transversely disposed surfaces on the spindle and the casing and into tumbler receiving pockets in the spindle, the tumbler wells and pockets being circumferentially spaced around a circle concentric to the lock axis and the tumbler pins being displaceable from said pockets by a tubular cylindrical key acting through drive pins slideably received in said pockets, the improvement which comprises: (A) the bore in the casing having a counterbore which opens to the front end of the casing and the bottom of which forms one of the transversely disposed surfaces of said interface; (B) the spindle being inserted into the bore through the front end thereof and being stepped in diameter to provide a head portion which lls the counterbore and a stem portion which protrudes from the rear of the casing. Remove the camor C-clip. Disc 32 is biased into a circumferential slot 60 defined on the inside surface or passage of the housing 16 by a circumferential, radially inwardly extending flange 62 which extends around the inside surface 64 of the housing 16. Opening locks of this type without the right key requires a little practice and the right tools. Door Closer A device for closing a door or gate automatically after opening. 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. inasmuch as withdrawal of the key entails displacement of the ball 33 from the keyway, it follows that the key and spindle must be returned to the position at which the hole 34 and the ball therein align with the recess 36.

Alternatively, a cap or other fastening device 18 may be cooperative with the outside surface of the housing 16 so as to hold the lock 14 in position in a cabinet or the like. 7 is a figure similar to FIG. 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. 4, the disc 32 is positioned to retain the inner cylinder assembly including the sleeve 26 and other component parts retained therein within the housing 16. 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. Dimple and axial/tubular locks are simply pin-tumblers with modified designs. BROCKHAGE Reverse Action Tweezers. the side of the plug 31 and the side of the bore 30. This collar, like the plug 31, is hardened steel. Door viewer Optical device fitted through a door to enable observation without opening the door. 5. (A plug followeris recommended) OR 1. the mouth of said recess being of a size to block any substantial movement of the ball circumferentially of the casing, so that the ball must be in the hole in the key before the key can be turned, and the key and spindle must be in a position of rotation aligning the ball with said recess before the key can be Withdrawn. The pin tumbler lock of claim 1, further characterized by means for preventing insertion and/or withdrawal of the key except when the spindle is in a predetermined position of rotation. 12 for removal it requires more than this for the ball 33 to identify the correct position of the cylinder.
