page_text: I, ROBERT POOLE ROE of 97 Green Lane, Stoneycroft near Liverpool in the County
of Lancaster, Chemist, 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 relates to a novel appliance for smokers' use which can be applied
to ordinary pipes, cigar holders, and the like, (hereafter called pipes) as at present
constructed. Or it may be attached to a pipe whose mouthpiece is slightly modified
for the purpose as hereafter described.
The objects of the improved appliance are to prevent the hot smoke, etcetera, from
impinging directly on to the tongue of the smoker, and also to prevent in a great
measure the saliva from the mouth entering the bore of the pipe. The failing of a
pipe is partly due to the entrance of saliva, with which the nicotine, etcetera, becomes
mixed, and is afterwards occasionally carried to the mouth. This may be injurious
and nauseous to the smoker.
Referring to the accompanying drawings:
:-
Figure 1 is a side elevation of a pipe with my appliance attached, the mouthpiece
and attachment being shown in section.
Figure 2 is a section on line a. Figure 1.
Figure 3 is a plan of the appliance shown in Figures 1 and 2.
Figure 4 is a section of a modified form of the appliance in position in a pipe
mouthpiece.
Like letters indicate corresponding parts in all the Figures.
The appliance consists essentially of a tube A preferably of metal, adapted to be
placed in the bore a of the mouthpiece of the pipe, said tube A having its outer end
closed and provided with a concave shield such as B, also preferably of metal. The
said tube A is provided with one or more openings 6, preferably at its sides, formed
just behind the shield B. These openings b allow of the exit of the smoke.
About concentric with the tube A, and preferably under the lower portion of same
is formed a short trough C, one end of which is attached to the shield B, the other
being adapted to bear against the end of the mouthpiece or to enter a curved groove c,

page_text: therein, which is formed for the purpose. As the tube A is preferably made of
thin metal and cut away or perforated near its attachment to the shield B, as
described, the piece or pieces of the tube which are left intact are preferably
thickened and strengthened so as to form webs d, whereby the appliance is rendered
stronger and the attachment of the tube A to the shield B is made more rigid.
Referring more especially to Figure 4; in some cases the trough C is continued
right round the tube A so as to form a short outer tube. In these cases I prefer
to extend the webs a little beyond the inner end of the trough C, so that they rest
against the end of the mouthpiece, instead of causing the end of trough to rest
against or enter a special groove in the mouthpiece. This enables the smoke to
escape around the outer edges of the trough.
Various slight modifications may be made in the above appliance without departing
from the scope of my invention. For instance, the shield may be of different shape
such as flat or convex, etcétera. Or it may be made of a double convex form and
may be either solid or hollow. Also the outer tube C may, if desired, be pressed
against or into a groove in the mouthpiece, suitable perforations or serrations being
provided for the passage of the smoke out of said tube C. Also the appliance
may be composed of earthenware, vulcanite, or other suitable material instead of
metal.
The mode of action is as follows:-
The tube A is pushed into the bore a of the pipe until the free end of the trough C
bears against the mouthpiece, or enters the slot c in the same. In the case of the
modified arrangement described above, the webs d would abut against the end of
the mouthpiece. The appliance is now held firmly in place, the snoke will be drawn
along the bore a, tube A, and out into the smoker's mouth through the openings b.
The smoker's tongue being kept from contact with the outlet of the tube A, by means
of the shield B, will be guarded from the direct impingement of the smoke, and, in
addition to this advantage, less saliva will run from the tongue into the bore of the
pipe. Any saliva which does pass the shield B will be retained by the trough or
outer tube C, whence it can be emptied at convenience.
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 1
claim is :-
1. An attachment for a tobacco pipe or the like, consisting essentially of a tube such
as A, adapted to enter into the bore of the mouthpiece of said pipe, and having its
outer end closed and provided with a shield such as B, the said tube being also pro-
vided behind said shield with a hole or holes to allow for the exit of the smoke,
substantially as and for the purposes described.
2. In combination with an attachment for a tobacco pipe or the like, substantially
as above described, an outer trough or tube such as C, adapted to bear against or
enter a slot in the end of the mouthpiece, and to act as a trap for saliva, substantially
as described.
3. The various forms of the attachment for a tobacco pipe or the like, each taken as
a whole, substantially as described.
