PROVISIONAL SPECIFICATION.
Improvements in Pipes, Cigar-tubes, and other Mouth-pieces.
1, BENJAMIN BRADFORD of 102 Dale Street in the City of Liverpool Tobacconist,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object a mouthpiece or pipe in which it will be practically
impossible for the saliva to enter the channel. Some months ago I designed a mouth-
piece in which the channel would take a sudden upward turn close to the exit and
then proceed onward to the pipe bowl. This succeeded perfectly but I have found
great difficulty in getting it manufactured. I have therefore designed the present
invention which accomplishes the same object but without the difficulties which were
attendant on the other.
I form the mouthpiece with a passage from the orifice for some considerable
distance very broad in one direction but narrow at right angles thereto. In this I
place a plug so shaped that the only passage for the smoke to pass through shall take
a sudden turn at right angles close to the orifice and again take a second turn at right
angles and lead on to the pipe bowl. In practice I prefer that this channel shall be in
a horizontal plane, that is in a plane at right angles or nearly so to the axis of the
pipe bowl. In order however to allow the saliva that enters this passage to run out I
form a nick or groove perpendicularly downwards so that when the pipe is in the
mouth the saliva that collects in the mouthpiece shall run out through this nick while
the smoke shall take the tortuous course in its passage from the bowl. The mouth-
piece and its plug are preferably made both of the same material.

COMPLETE SPECIFICATION.
Improvements in Pipes, Cigar-tubes, and other Mouth-pieces.
1, BENJAMIN BRADFORD, of 102 Dale Street, in the City of Liverpool, Tobacconist,
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:
This invention has for its object a mouthpiece or pipe in which it will be practically
impossible for the saliva to enter the bore or smoke duct. Some months. ago I designed
a mouthpiece in which the bore took a sudden upward turn close to the exit and then
proceeded onward to the pipe bowl. This succeeded perfectly, but I have found great
difficulty in getting it manufactured. I have, therefore, designed the present inven-
tion, which accomplishes the same object but without the difficulties which were
attendant on the previous design.
The invention may be understood from the following description, reference being
bad to the accompanying drawing, in which :-
Figure 1 is an elevation of the pipe, showing the mouthpiece in section with my
improved plug in position therein, and
Figure 2 is a section through both mouthpiece and plug, taken on a plane at right
angles to the section shown in Figure 1.
I form the mouth or orifice A of the bore a of the mouthpiece B very broad in one
direction but narrow at right angles thereto. This widened orifice extends for a con-
siderable distance up the bore as seen in Figure 2.
In this widened orifice, I place a plug B so shaped that the only passage for the

page_text: smoke from the hore a shall take a sudden turn at right angles to the bore close to the
outer end of the orifice, as at d, and again take a second turn at right angles, as at d,
before reaching the outer end of the mouthpiece. In practice, I prefer that this
channel d d shall be in a horizontal plane, that is, in a plane at right angles or nearly
so to the axis of the pipe bowl C.
In order, however, to allow the saliva, that enters the part d' of the passage, to run
out, I form a nick, groove or duct E in the lower wall of said part, so that, when the
pipe is in the mouth, the saliva that collects in the part of the mouthpiece shall run
out through the nick E, while the smoke shall, in its passage from the bowl, take the
tortuous course above described.
The mouthpiece and its plug may be made of the same material, or of different
material. In the form shown, the plug D is made by a simple bent metallic plate of
Z-shape, having the passage d formed in its intermediate portion. The plug may be
very readily held in position in a removable manner by a twisted wire stem F, by
means of which also the bore of the mouthpiece may be cleaned from time to time by
simply withdrawing the plug..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
In a pipe or other like mouthpiece, a plug such as D so constructed and arranged
within the widened orifice of said mouthpiece that a tortuous smoke passage is formed,
the onter portion of said passage being provided or not with a saliva duct, substantially
as and for the purpose described.
