Abstract

1,101,456. Changing Combination of axial pin tumbler lock mechanisms. CHICAGO LOCK CO. 16, March, 1965 [26, June, 1964], No. 11187/65. Heading E2A. An axial pin tumbler lock assembly 10 has a lock shaft provided with a circular forward end face presenting a series of forwardly opening bores 33 for receiving a series of replacement tumblers 32A and is combined with a two-part assembly jig for placing the replacement tumblers in the bores, the jig including a generally cylindrical shell 70 having a rear end wall provided with open ended bores corresponding to the number and disposition of the bores 33, replacement tumblers 32A slidable in the bores in the end wall, friction means restraining the tumblers against free sliding in the bores, and a cylindrical pusher tool 62 receivable telescopically and endwise in the shell 70 and having a circular rear end face from which there projects a series of pusher pins 66 corresponding to the number and disposition of the bores in said end wall, the pusher pins 66 being adapted for entry into the bores in the end wall so as to engage the tumblers and force them into the bores 33. As described the jig is used to replace the original tumblers 32 in the bores in the lock shaft, by tumblers 32A so that the combination of the lock is changed. To effect this a cap 36 of the lock is removed to expose the tumblers 32, 'and these are withdrawn from the bores 33 by a ceramic magnet 64 at one end of the tool 62. The shell 70 is then placed against the lock assembly so that a bore in the end wall thereof receives a pilot post 42 of the lock shaft, and the shell is positioned by a lug 84 thereon entering a groove 86 in the post 42. The tool 62 is then telescoped into the shell 70 so that the pusher pins 66, which are spring loaded, contact the replacement tumblers 32A, the tool being located in the shell by a spline 80 engaging in a groove 78. The tumblers are held in their bores by a rubber O-ring which partially intersects the bores, and the tumblers are pushed from their bores into the bores 33 by the pins 66. The two parts of the jig are then removed from the lock assembly and the cap 36 replaced. The shell 70 is preferably of plastics material e.g.transparent "Lucite" (Registered Trade Mark).
