This invention relates broadly to smoker’s accessories

the case of a pipe with a small bowl or one that is
heavily caked to the extent that the ?nger cannot be
inserted therein. Once the pipe has been lit, however,
tamping the hot tobacco in the bowl is a most uncom
fortable procedure if performed with the ?nger; yet, it
must be done to keep the hot ashes from falling out onto
clothing and to compress the humid layer of ashes in
the top of the bowl so that combustion of the remaining
tobacco may continue. As a result many pipe smokers
attempt to protect their ?ngers from the hot tobacco by

Now, in FIGURES 5 and 6, it will be seen that means

invention have been illustrated in the accompanying

or adjacent to the bottom 14. The purpose of this thermal
barrier is, of course, to insulate the tip of the user’s
?nger from the hot metal at the base of the tamper.
Preferably, the so-called thermal barrier 28 should be
formed from a thermal insulating material able to with
stand temperatures of approximately 1000° F. or more

within the broad teaching hereof; hence, it is our inten
tion that the scope of protection afforded hereby shall
be limited only insofar as said limitations are expressly
set forth in the appended claims.

Finally, with reference to FIGURES 3 and 4 of the
drawings, it will be seen that the outside of the body 12
is provided with a vertically-ribbed surface that has been
indicated broadly by numeral 36 and which constitutes
the reamer portion of the instant invention. The ribbed
surface is formed by a series of alternating grooves 38
and lands 40. The grooves ‘38 are substantially of part
circular section in the particular form shown so that they
de?ne with the lands 40 sharp edges 42 along their line
of intersection. These sharp edges are designed to scrape
the cake (not shown) from the inside of the pipe bowl
when the device is placed on the user’s ?nger, inserted
into the bowl and rotated with a reaming-action against
the internal surface of the latter. For this reason, the
maximum outside diameter of the body ‘12, with the ex
ception of rim 16, should preferably be somewhat less
than the opening into the pipe bowl so that the reamer
can be inserted substantially all the way into the bottom
of the bowl.
Having thus described the several useful and novel
features of the combination pipe tamper and reamer of
the present invention, it will be seen that the many worth 60

sulating material of greater diameter than the minimum
inside diameter of the body portion ‘and less diameter
