Our invention relates to smoking pipes, and
has among its objects and advantages the pro
vision of improved cleaning and ?ltering facili
ties for such pipes.

the body and arranged in right angular relation

While the core ex
tends from side to side of the body 46, its ends
terminate short of the ends of the ?lter body.
This constrains the smoke to enter the side of the
