Improvements in Covers for Tobacco Pipes.
I, ARCHIBALD ALLAN PERCY of 38 Sauchiehall Street in the City of
Glasgow, Tobacconists' Furnisher, do hereby declare the nature of this invention
to be as follows:-
:-
This invention which relates to improvements in covers for tobacco pipes has for
its object to so construct the cover as to adapt it to pipes having different sizes of
bowls the said cover consisting of a disc or plate which has two channels converging
from the circumference towards the centre cut in it in a straight line. Through
these channels there projects downwards two prongs or horns which may be
arranged to grip upon either the interior or exterior of the bowl and each of the
said prongs or horns is connected to a pushing part or bar which works in a
cylindrical or other shaped channel attached to or formed on the upper surface of
the disc or plate. The pushing parts or bars overlap each other, that is to say,
the push for the right hand prong or horn is operated from the left hand side of the
lid or cover and vice versa and within the channel the pushing parts or bars and the
prongs or horns have provided in conjunction with them a spiral or other spring or
springs so arranged that by moving the bars towards each other the prongs or
horns are either contracted or extended to suit the interior or exterior diameter of
the bowl.

COMPLETE SPECIFICATION.
Improvements in Covers for Tobacco Pipes.
I, ARCHIBALD ALLAN PERCY of 38 Sauchiehall Street, in the City of
Glasgow, Tobacconists' Furnisher, 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 covers for tobacco pipes and it
consists in so constructing the cover as to adapt it to pipes having different sizes of
bowls.
The invention is illustrated under several modifications on the accompanying
drawings the figures on which are for greater clearness drawn to an enlarged scale.
In the arrangement shown in section by Figure 1, in plan by Figure 2 and in
elevation by Figure 3, the cover consists of a disc or plate a which has two slots b
converging from the circumference towards the centre cut in it in a straight line.
Through these slots there projects downwards two prongs or grips e which may be
arranged to hold upon either the interior or exterior of the bowl. Each of the
said prongs or grips is connected to a push or bar d which works in a curvilinear or
other shaped channel e attached to or formed on the upper or under surface of the
disc or plate a.
The pushes or bars d for each grip c may operate from the same side of the
cover as that at which its connected grip is situated or as shown by the modification
illustrated by Figures 4, 5 and 6 in which the grips c are arranged to fit on the
outside of the pipe bowl they may overlap each other, that is to say, the push d
for the right hand prong or grip c is operated from the left hand side of the cover
and vice versa.

page_text: When the latter arrangement is adopted the slots b in the cover are dispensed
with but in both cases the pushing parts or bars and the prongs or grips chave
provided in conjunction with them a spiral or other spring or springs so arranged
that by moving the bars towards each other the grips are either contracted or
extended to suit the interior or exterior diameter of the bowl.
Figure 7 shows in elevation a modification in which the plate or disc a instead of
having a channel e to contain the spring or springs is covered over by another
plate which is connected to the plate a in any convenient manner. The plate or
disc a has ventilating holes or apertures made in it and with the arrangement
Figure 7 the plate may either have like apertures on the top or around the
circumference.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
A cover for tobacco pipes adapted to fit various diameters of bowls and wherein
there are combined with the covering plate or disc holding grips operated by pushes
or bars and maintained in adjusted position by a spring or springs substantially as
described with reference to the drawings annexed.
Dated this Eleventh day of October 1893.
