Improvements in Tobacco Pipe Plugs.
We, GEORGE GRICE AND COMPANY LIMITED, of Walpole Street Nail Works, -
Blackburn, in the County of Lancaster, Tack Manufacturers, and RICHARD
HOLDEN, of Blackburn aforesaid, Brewer, do hereby declare the nature of this
invention to be as follows:-
The first part of this invention relates to improvements in tobacco pipe plugs,
and consists in forming them of differently shaped spheriods preferably of metal,
but they may be made of other material; the desire being to intercept the nicotine.
In one form, the spheriod is made somewhat hemispherical, but instead of.
having a flat face, the same is either concave or convex. The figure is hollow
inside, and the concave or convex surface respectively is pierced with holes.
High up the external sides of these pipe plugs are also formed holes, and channels
or grooves proceed from them to the bottom of the pipe bowl. The nicotine from
the smoke in its passage through the plug is condensed on the inside surface of the
spheriod and subsides to the bottom of the well, whilst the smoke passes through
the holes in the concave or convex face respectively, and emerges from the holes
at the sides, traverses the grooves or channels leading from them to the bottom of
the pipe bowl, and eventually enters the pipe stem.
Instead of being convex, the protrusion of the upper face may be more pro-
nounced, and have the appearance of a cone, whilst the bottom may remain
hemispherical or cup or bell shaped, the latter inverted.

Improvements in Tobacco Pipe Plugs.
We, GEORGE GRICE AND COMPANY LIMITED, of Walpole Street Nail Works,
Blackburn, in the County of Lancaster, Tack Manufacturers, and RICHARD
HOLDEN, of Blackburn. aforesaid, Brewer, 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 improvements in tobacco pipe plugs,, and consists in
forming them of differently shaped speroids, preferably of aluminium, but they
may be made of other metal or material; the desire being to intercept the nicotine.
In one form, the speroid is made somewhat hemispherical, but instead of

in the inside, and the concave or convex surface is. pierced with holes.
High up the external sides of these pipe plugs are also formed holes, and channels
or grooves proceed from them to the bottom of the pipe bowl. The nicotine from
the smoke in its passage through the plug is condensed on the inside surface of the
spheroid and subsides to the bottom of the well. The smoke after passing through
the holes in the concave or convex face respectively, emerges from the holes
at the sides, and traversing the grooves or channels leading from them to the
bottom of the pipe bowl, eventually enters the pipe stem.
Instead of being convex, the protrusion of the upper face may be more pro-
nounced, and have the appearance of a cone, whilst the bottom may remain
hemispherical or cup or bell shaped, the latter inverted.
In the accompanying drawings,
Figs. 1, 2 and 3 represent tobacco pipe plugs constructed according to our
invention.
In Fig. 1 the top of the plug is convex in form; in Fig. 2 it is concave; and in
Fig. 3 somewhat conical. The body of the plug is cup or bell shaped, or hemi-
spherical. The plug is hollow internally, and the smoke passes through the
holes A at the top, then emerges out of the holes B at the sides, traverses the
grooves C on the external sides of the plug leading to the bottom, and finally enters
the stem. In its course, it is thus purified of nicotine and products of essential
oils, which the tobacco contains, and which subside to the bottom of the well or
plug.
The plug may be made of aluminium or other metal or material.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
Tobacco pipe plugs of the form shewn, and provided with holes A and B and
external side grooves C for the passage of the smoke, substantially as described
and illustrated.
