COMPLETE SPECIFICATION.
Improvements in Tobacco Pipe Bowl Covers or Stoppers.
I, ERNEST JOHN FAWKS, of Bromsgrove, in the County of Worcestershire,.
Mechanical Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly doscribed and ascertained in
and by the following statement:-
This invention relates to a new or improved construction of tobacco-pipe
bowl-cover or stopper, the object being to form a readily attachable and detachable
cover for the pipe whether whilst smoking is going on, as in windy weather for
instance, or when the pipe has to be put in the pocket or elsewhere out of use.
In the drawings accompanying this specification, Fig. 1 is a plan, Fig. 2 is side
view, Fig. 3 detached view of the spring attaching piece, Fig. 4 is a side view
partly in section showing a modification of construction, and Fig. 5 is a plan of
Fig. 4.
a is a central pin, with a screw button b, c is a plate attached to said pin a
and perforated to correspond at a certain point of location with perforations in
plate e, the spiral spring band d may be attached rigidly at one end to the pin
In some
as at d', or it may be attached at the other end to the plate c.
cases the end of the spring band at d' may be pussed freely through so as
to have freedom of play in the slot of the pin a, when so fitted, allowing of
expansion and construction to a greator or lesser volute of the spring pioce d.
In this case the plate c may be fast upon the pin a and the outer end of
the voluto spring piece may be fast to the said plate c, as indicated at d. The
spring piece may with advantage be made of aluminium.
The object of the expansion and contraction of the volute spring piece is to
adapt the stopper to different bowls of pipes, e is a loose plate perforated and
held upon pin a by screw button b so as to allow of the same being turned to
allow of its perforations corresponding with perforations or openings in plate c.
As shewn in Fig. 2, the lower edge of the spring piece d is burred or turned over
so as to more readily hold in the pipe bowl opening.
As shown in Figs. 4, and 5, the plate e is made or fitted with a downwardly
projecting tooth and the bell shaped plate g is attached to the turning pin
and knob a b, eccentrically thereof so that the tooth and plate 9 may be
introduced into the pipe bowl Fig. 4, and when turned into position indi-
cated by Figs. 4 and 5 the cover will be held between the edge of plate g
and the tooth.
Having thus 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. In a tobacco pipe bowl cover or stopper as herein set forth, the spring band d
combined with spindle a, plate c and button 6 as and for the purpose specified.
2. In a tobacco pipo bowl cover or stopper the spring band d, combined with
spindle a, plate c, button b and perforated cap plate e substantially as and for
the purpose specified.
3. In a tobacco pipe bowl cover as set forth, the combination with the plate,

page_text: of the tooth or projection and the bell shaped eccentric plate g attached to
the pin a and operated by the turning of the button 6 to ensure attachment
of the pipe bowl cover as and for the purpose herein set forth.
Dated this 1st day of September 1896.
