1, ROBERT WALLACE, of 255 Onslow Drive, Dennistoun, in the County of
Glasgow, North Britain, Engineer, do hereby declare the nature of this invention
to be as follows, that is to say :-
My said invention has for its object by improvements in the construction of
tobacco pipes to facilitate the cleaning of them and to prevent the drawing of
objectionable matters through their stems.
In carrying out the invention the stem has formed through it near the bowl, an
opening like that of a conical-plug stopcock, the stem being by preference enlarged at
the part. According to some modifications a plug shaped to fit the opening is used, a
small passage being formed across the middle of it or a groove being formed round it.
According to other modifications disks may be provided for closing the ends of
the opening, such disks being formed with a central connecting stem, or being
separate and in either case being screwed or fitted tightly into the ends of the
stem opening. Or the stem opening may be made with projecting lips over which
caps may be fitted or screwed. Or a pair of closing disks or caps may be connected
by a spring clip band passing round part of the pipe; or the outside of the part
having the opening through it may be made cylindrical and a metal ring or short
tube may be fitted to slide thereon to close the opening or to expose it. A piece
of sponge or other absorbent material may be placed in the opening.
When the pipe stem becomes obstructed the plug, or the disks, or the caps can
be easily removed, and the opening can be cleaned whilst if a wire or instrument
be passed through the stem it will be seen at the opening and obstructing matter
can if necessary be removed before withdrawing the wire.
Dated this Eighteenth day of April 1895.

I, ROBERT WALLACE, of 255 Onslow Drive, Dennistoun, in the County of
Glasgow, North Britain, Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, that is to say :-
My said invention has for its object by improvement in the construction of
tobacco pipes to facilitate the cleaning of them and to prevent the drawing of
objectionable matters through their stems.
In carrying out the invention the stem has formed through it near the bowl, an
opening which may, according to various modifications, be closed by either a conical
plug (like that of a stopcock), or by disks connected by a central stem or separate,
and either fitted tightly or screwed into the opening, or by disks connected by a
spring clip band, or by a metal ring or short tube; and in some cases the opening
may be only partly through the stem.
And in order that my said invention and the manner of performing the same

page_text: may be properly understood I hereunto append a sheet of explanatory drawings,
to be hereinafter referred to, and showing modifications of tobacco pipes as made
according to my invention.
Figures, 1, 2, 3, 6, 7, and 8, of the drawings are sectional views of separate
modifications. Figure, 4, is an outside view, and Figure, 5, is a sectional view as
at right angles to Figure, 4, of another modification.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
In the modification shown in Figure, 1, the stem, A, has formed through it near
the bowl, B, an opening, C, like that of a conical-plug stopcock, the stem being by
preference enlarged at the part. A plug, D, shaped to fit the opening, C, is used,
a groove being formed round it or a small passage may be formed across the
middle of it. The plug, D, may be secured by a nut, G, on the under side of the
stem, or it may fit tightly enough to require no further fastening.
In the modifications shown in Figures, 2, and 3, separate disks or short plugs, H,
and J, are provided for closing the ends of the opening, C, the opening being in
this case tapered from both sides towards the centre of the stem, A. In the
modification shown in Figure, 2, one disk, H, is formed with a central stem, K, on
which the other disk, J, is screwed so as to cause both disks to fit tightly into the
ends of the opening, C. In the modification shown in Figure, 3, the two disks, H.
and, J, are separate and are screwed into the ends of the opening, C.
In the modification shown in Figures, 4, and 5, a pair of closing disks, H, and J,
in shape like spherical segments are connected by a spring clip band, L, passing
round part of the pipe, and having formed on it two projections, M, by compressing
which, the disks can be sprung outwards, so as to be placed on or removed off the
stem opening, C.
In the modifications shown in Figures, 6, and 7, the outside of
the opening, C, through it is made cylindrical or slightly tapered.
tube, N, is fitted, in the case of the modification shown in Figure,
the pipe stem, A, and close the opening, C, or to expose it, and in
modification shown in Figure, 7, the tube is arranged to turn on
and allow of holes, P, (which in this case are formed in the me
brought opposite the opening, C.

In the modification shown in Figure, 8, rubber rings, Q, are inseed in circum-
ferential grooves in the stem, A, close to the opening, C, and a mal ring, N, is
passed over them so as to bear on them and insure the joint being tight.
In the modifications shown in Figures, 6, 7, and 8, the opening, C, may be only
partly through the stem, A, and in any modification, where convenient, a piece of
sponge or other absorbent material (not shown) may be placed in the opening, C.
When the pipe stem, A becomes obstructed the plug, D, or the dists or plugs, H,
and J, can be easily removed, and the opening, C, can be cleaned, whilst if a wire
or instrument be passed through the stem, it will be seen at t opening and
obstructing matter can if necessary be removed before withdrawing the wire.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the sume is to be performed I declare that what I
claim is
In a tobacco pipe forming through the stem near the bowl an opening passing
through and at light angles to the stem in combination with any of the specified
devices for closing the same, the parts being constructed substantially as and for
the purposes hereinbefore described.
