PROVISIONAL SPECIFICATION.
Improvements in Caps for Tobacco Pipes.
I HENRY PAULDEN MORTEN of 4 Fleetwood Street, Southport in the County
of Lancaster, Gentleman, do hereby declare the nature of this invention to be as
follows:-
My said invention relates to the caps which are sometimes placed on the tops of
the bowls of tobacco pipes, chiefly for outdoor use, to prevent the ingress of wind
or rain or to keep the tobacco and ashes in the bowl when the pipe is placed in the
pocket. When ordinary caps are used fitting closely upon the bowl, the top of
the cap is usually perforated to admit the requisite air to the tobacco. These
perforations are however usually insufficient to admit a proper proportion of air
and moreover such perforations are apt to allow the ashes to escape or to give
access to rain.
According to my invention I provide a cap which while admitting air freely to
the bowl of the pipe has no perforations and none of the disadvantages arising
therefrom. My improved cap is made preferably of thin sheet metal with a
corrugated rim so that when placed upon the top of the bowl the corrugations
form air conduits or passages between the rim and the outside of the bowl. The
air enters at the foot of these passages and flowing upward passes over the top
edge of the bowl into the interior. Thus one portion of the passage is at right
angles to the other and as a consequence any sudden up-draughts are broken or
diffused while it is impossible either for the ashes to escape or for the rain to
enter.
The cap might be variously modified in form and construction so long as air
passages between the cap and the bowl are provided. In some cases the rim of
the cap might be made perfectly plain and the corrugations or grooves formed in
the side of the pipe bowl.
Pipes fitted with caps in accordance with my invention, being less liable to the
escape of glowing ashes, are not so liable to cause damage by fire.

COMPLETE SPECIFICATION.
Improvements in Caps for Tobacco Pipes.
1 HENRY PAULDEN MORTEN of + Fleetwood Street, Southport, in the County
of Lancaster, Gentleman, 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 and accompanying drawings:-
My said invention relates to the caps which are sometimes placed on the tops of
the bowls of tobacco pipes, chiefly for outdoor use, to prevent the ingress of wind
or rain or to keep the tobacco and ashes in the bowl when the pipe is placed in the
pocket. When ordinary caps are used fitting closely upon the bowl, the top of the
cap is usually perforated to admit the requisite air to the tobacco. These
perforations are however usually insufficient to admit a proper proportion of air
and moreover such perforations are apt to allow the ashes to escape or to give
access to rain.
According to my invention I provide a cap which while admitting air freely

page_text: to the bowl of the pipe has no perforations and none of the disadvantages arising
therefrom.
In the annexed drawing Fig. 1 is a perspective view of a tobacco pipe with my
improved cap placed upon the bowl.
The cap a is made preferably of thin sheet metal with a corrugated rim or dished
edge as clearly shown in the drawing, so that when placed upon the top of the
bowl the corrugations form air conduits or passages between the rim and the
outside of the bowl. The air enters at the foot of these passages as shown by
the arrows and flowing upward passes over the top edge of the bowl into the
interior. Thus one portion of the air passage is at right angles to the other and
as a consequence any sudden up-draughts are broken or diffused while it is
impossible either for the ashes to escape or for the rain to enter.
The cap a might be variously modified in form and construction so long as air
passages between the cap and the bowl are provided. In some cases the rim of the
cap might be made perfectly plain and the corrugations or grooves formed in
the side of the bowl as shown in Fig. 2. Pipes fitted with caps in accordance with
my invention being less liable to the escape of glowing ashes are not so liable to
cause damage by fire.
•
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 :-
1. A cap for application to the bowls of tobacco pipes and formed with
corrugations in the rim or dished edge so that when placed on the bowl these
corrugations form passages through which the air finds its way to the inside of the
bowl substantially as described and shown.
2. The combination of a cap having a plain edge with a pipe bowl having ridges
or grooves in the part over which the cap fits the said ridges or grooves forming
air passages substantially as described and shown.
