The present invention is generally directed to
locks and is particularly concerned with cylinder
locks of the type having a tumbler and key re
ceiving rotatable barrel cooperatively associated
into the barrel to permit adequate rotation of the

slldably disposed in a. housing of a shell inde . vparts of thebutterily >slots and project> into the
tumbler receiving bores of theK-barrel and thus
pendent of the barrel> _and in such manner that
upon the insertion of a properly mated key into
' vthe barrel the tumblers and the :superimposed
serve 'aslook means to prevent rotation of the
sleeve and barrel. The invention comprehends

as a further object the provision of a. relatively.

fashion to permit appreciable rotation of the
barrel relative to the shell. . Cylinder locks of the

type 'referred Vto are capableof being readily
picked by a skilled but unauthorized operator in

practice is well- known in the art and the precise
process employed need` not be pointed out specifi
_callyA apart from callin'g'attention to the fact
that a cylinder lock can be picked because of the ‘
ation with thekey receiving barrel to initially
resist proper raising of the driving members above
the outsideksurface of the sleeve during pickingl
operations and wherein subsequently. the sleeve .
is rotatably displaced in respect to these driving
members whereby the latter are caused to be
