1 Claim.
This invention relates tothat class of objects
known as smokers’ articles and ‘in particular to
smokers’ pipes.
Pipes of various types are known which have
» been lined with, various compositions such as
licorice and a solid, syrup‘ and a solid or honey
and a‘ solid. It will be noted that these linings
all have as a base, a liquid substance which is likely
to be dried out over a period of time if the inte
10 rior of the pipes is subjected to the varying con—
ditions of the air known to exist in warehouses,v
stores or other places of storage or display. The
linings may thus be subject to. chemical or physi
cal changes.
3 It is an object of this invention to protect
these linings from variations of the atmosphere.
It is another object of this invention to protect
thelining from- the chemical or physical change
or injury by providing simple packing and closure
20 means all within the bowl of the pipe.
It is well known also that tobacco has been
used as the solid referred to above to form the
lining, while the licorice was used to bind the
tobacco and sweeten the pipe. This has been
25 found unsatisfactory since the tobacco burns out
of the pipe lining and'leaves a gummy mass ‘of
licorice upon the walls. of the pipe. The pores.
‘of the pipe become clogged, and the pipe be

tained in the bowl by a suitable lid or cover glued
or otherwise held upon the outside of the bowl.
. These‘pipes were unsatisfactory because the glue
gummedthe pipe and smelled when it, became
hot. Also this and other closure retaining means 5
marred the outer surface of the pipe.
It is ‘an object ‘of this invention to provide a
pipe vof ‘a permanent type containing tobacco.
It is a further object to retain the tobacco with
in the pipe by closure, means within the‘ pipe such
that the beauty of the bowl is not impaired.
These and other objects and advantages will
appeanfrom the following description of my
invention in, which I refer to the appended draw
ing throughout the various ?gures of whichlike

‘As clearly shown in the preferred embodiment
of my invention depicted in Figs. 1 and 2, I have

is an object. tov provide a pipe with such a porous
binder, and it is a further object to cure this
lining with tobacco while the pipeis on display.v
It is yet another object of this invention to.‘ pro
vide economical‘ and easily removed closure
means for retaining the tobacco within the pipe.‘
Another object is to provide a pipe which may
be- offered for sale- ready tobe smoked. And it
i is. 'a further object to provide for the smoking
public a pipe lined 0r unlined and partially cured
with the proper tobacco.
It is not generally known among‘smokers that
the ?rst pipeful of tobacco smoked in a new pipe
45 should be a pure tobacco uncontaminated with
prune juice, licorice or other gummy substances.
Tobacco of the preferred type is not readily ob
tainable in quantities small enough for the single
pipeful needed. It is an object to provide a pipe
50 packed with tobacco of the type correct for
breaking in a pipe.
I am aware that ?lled pipes of various kinds
have been made and offered for sale. These
pipes have been, so far as I am aware, of a very
55 temporary material. Also the tobacco was re
plastic mass of ‘pure honey and a porous, non
combustible, solid material which has'been com
minuted to. the desired degree of ?neness. When
this plastic» mass has been mixed in such propor
tionsfas‘tosform a plastic mass which has a very. 35‘
slight ?ow coei?cient it is applied to the inner
surface ofv the pipe in any manner such as by
moulding about .a collapsible core. ‘The pipe
may be treated‘ in any way to cause the lining to
set,'such as by ‘baking. The baking process, if
this be used, must, however, be‘stopped before
the, honey becomes dried out to such an extent
as to‘icrumble.v The invention contemplates the
continued- maintenance of the'lining in that‘ de
gree of moisture which is best suited to carry 45
out the purpose of the lining.'
While I have hereto-fore referred to a briar
pipe with a lining, it will be manifest that it is
Within the spirit of my intention to embody
my invention in pipes having varous shapes of 50
bowls and various combinations of materials,
whether moulded or milled. It will be obvious
that I may use a lining or not because the struc
ture alone, as well as the discovery of the need 55
for and the bene?cial result of the structure, is
an important part of my invention.
Referring to Figs. 1 and 2, the lining material
is ?nished in a convex curve 6 fora space from the
top of the lining.
The inner surface of the lining,
or the inner surface of the pipe bowl, if no lin
ing be used, is then curved concavely as at 8 to
form an annular groove. While it is not essential
that this groove be of any particular width, that
10 is, from top toward the bottom of the pipe, it
is preferable slightly wider than the thickness of
well known three-ply paperboard commonly
known as cardboard.
The pipe bowl is next packed with an un
15 sweetened tobacco l0 possessing a degree of mois
ture which may be found from experiment to be
most suitable for “breaking in pipes.” A clear
Havana type tobacco which is slightly crimp out
has been found by me to be most suitable, since
20 this leaves the pipe in a sweet ungummed con
dition. I have found also that this type of to
bacco has bene?cial results as a curing tobacco
since it permeates the porous material of the lin
ing or the pipe bowl and impregnates these mate
rials with a sweet tobacco taste.
The degree of moisture which I have found
most suited for retaining the pipe bowl or lining
in condition may be determined by touch rather
than by the use of complicated testing apparatus.
The tobacco should be such that it will feel slight
ly dry but will not powder when it is rolled be
tween the hands.
I use a slightly crimp cut tobacco which is
packed in the bowl up to the lower limit of the
annular groove 8. A closure member 12 is then
pressed into the pipe bowl until it springs into
place in the groove 8.
Preferably this closure member consists of a 3
ply paper disc having a diameter slightly less
than the distance from the bottom surface to the
opposite bottom surface of the groove 8. Per
fect ?t is not essential since the above mentioned
crimp cut tobacco has the tendency to expand
by uncurling. This expansion of the tobacco
45 urges the disc tightly against the upper side of
the groove and insures a seal. It will be obvious,
of course, that I may use oval shaped closure
members for pipes with oval bowls since the
invention is not limited to a particular shape of
50 bowl. Also I may, if I ?nd it desirable, treat
the closure member with a moisture-proo?ng
compound before the closure members are die
cut from the sheet. Paraffin might, for instance,
be spread upon the surfaces of the paper sheet or
55 a coating of shellac applied. Also a cellophane
or other moisture-impervious material could well
be used in combination with these closure mem
bers. It would be economical to apply a sheet of
cellophane to the sheet of paper which is to be
60 die-cut to form the closure members. The
laminated fabric would then be out out in a single
As shown in a second embodiment of my in
vention depicted inFigs. 4 and 5, I may provide
the disc l2 with an integral tab for ease of re
moval. The tab I4 may be formed by making
a U-shaped line of cut I6 part way through the
body of the disc.
It will be obvious that I have discovered a
simple form of closure member which is prefer
ably for use in retaining a quantity of tobacco
in unused pipes. It will be equally manifest
that the closure member is not limited to use with
new pipes. For instance. I may supply a quan 10
tity of suitable discs to be later used to retain
the ashes and unused portion of the tobacco from
spilling into a smoker’s pocket or on a desk or
I am aware that others have disclosed
various means for the accomplishment of this 15
same end.
However, no other person has pro
vided a closure member of such convenience and
simplicity. Nor has anyone produced a closure
member which may be so economically produced
that it may be thrown away after one use and at 20
a slight cost. Metallic devices which are retained
by spring arms have been used but these have
many disadvantages, such, for instance, as the
necessity of folding and unfolding the arms.
Others have disclosed a sack-like device of rub 25
ber and asbestos which may be rolled upon the
pipe. Yet other pipes have been provided with
a flat base so that they may be kept in an up
right position.
I have found that I may use the disc described. 30
above to retain tobacco and ashes in a partly
smoked pipe. The ashes which remain above the
burning tobacco act as an excellent insulator,
which is effective to prevent burning of the paper
disc for the short time that the tobacco continues 35
to burn. The lack of oxygen in the closed pipe
bowl assures prompt extinguishment of the
smoldering. While I have declared that card
board of a well known type and cut into the
proper shape may be used for closure members in 40
burning pipes, it is Within the contemplation of
my invention that I may use a non-combustible
or a poorly combustible material such as asbestos
paper of a desired thickness or combinations of
asbestos paper and a combustible paper. I may 45
also use a wood or linen pulp paper which has
been so highly compressed that it has a high re
sistance to heat.
While I have described the preferred embodi
ments of my invention, it is to be understood that 50
I do not limit myself to the exact examples de
clared, but I may make modi?cations or improve
ments thereof without departing from the spirit
of the invention.
I claim:
A pipe comprising a bowl, a lining covering the
inner surfaces of said bowl, an annular groove in
said lining spaced from the top edge of said lin
ing, a substantially ?at imperforate disc of less
peripheral extent than said groove adapted to 60
have a seal in said groove, and a tobacco ?lling
in said pipe exerting an upward pressure upon
said disc to effect said seal.
