Pattern matching in lists

MemberQ easily tests whether a single integer appears in a list
of integers.  Suppose, however, that I want to test not for a single
integer but for two or more consecutive integers, e.g., to see whether
{1,4,6} is a member of {1,3,2,6,5,1,4,6,3,9}.  I can do this by
converting both lists into strings and then using string-matching
functions, but is there some way of doing it directly without that
conversion?

Thanks.
