page_text: FREDERICK ARTHUR PYKE, 13 Abbey Grove, Bolton, in the County of Lancaster,
Clerk, do hereby declare the nature of this invention to be as follows:
-
This invention consists of improvements in and relating to pipe cleaners and
has for its object the provision of efficient arrangements whereby tobacco pipes
and the like may be cleaned by air being pumped or forced through the stem
thereby cleaning out the smoke passage.
For example I provide a cone shaped adaptor of rubber or other suitable
substance adapted to fit into the bowl of a pipe. Through the centre of the
adaptor a hole is provided and one end may be recessed to accommodate the end
of a pump such for instance as that commonly used for the purpose of inflating
pneumatic tyres.
A metallic tube may be placed through the centre of the rubber portion of the
adaptor one end of which projects beyond the rubber portion and may bear a
suitable washer and screw thread for the purpose of being screwed into the
pump to make an airtight connection between the pump and the adaptor.
A shoulder may be provided on the tube which serves to prevent its displace-
ment in the rubber portion.
This pipe may be held in position by hand whilst air is being forced through
it, or a case to accomodate it may be provided suitably shaped & with provision
made for the inlet and outlet of air to & from the pipe and for the deposit and
withdrawal of the pipe.
Dated this Eighth day of September 1898.
I, FREDERICK ARTHUR PYKE, of 13, Abbey Grove, Bolton, in the County of
Lancaster, Clerk, 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, that is to say:-
It relates to a new or improved device for cleansing tobacco pipes and consists
in constructing same of such a form or construction as to enable the cleansing
of said pipes by the removal of objectionable liquid and other matter from them,
to be easily and expeditiously performed.
To attain this I make use of parts constructed and arranged as hereinafter
described and as illustrated by the accompanying sheets of drawings in which:-

page_text: Fig. 1 is a perspective view illustrating the application of my improved device
as in use for cleaning a tobacco-pipe.
Fig. 2 is a sectional elevation drawn to an enlarged scale showing the parts
illustrated by Fig. 1.
Figs. 3 and 4 are similar views to Fig. 2 but are illustrative of modifications
hereinafter described.
Figs. 5, 6 and 7 are drawings in detail of parts hereinafter referred to.
In carrying my invention into effect I make use of a plug or stopper a of
india-rubber or other suitable substance, the same being preferably formed of a
conical shape so as to enable it to fit tightly within the bowls b of varied sizes
of pipes c while an aperture a¹ is made in it of a desirable shape (somewhat as
shown at a) to take tightly over the nipple of an air-pump d, from this it
will be seen that when the parts are in position as shown by Fig. 1, air may be
forced by the air-pump through the bowl and stem of the pipe to carry with it
the undesirable matter thus effecting its removal as desired.
.
Instead of the nipple d' of the air-pump d taking within the plug a as above
described it may take over the screwed part cl of the joining piece e (see Fig. 7)
the opposite end of which takes within the plug a, said joining piece e being
provided with an annular flange f and a leather or other washer f¹ in order to
keep the several parts air-tight.
The tobacco-pipe c and plug a may be held in position by the hand of the user
as shown by Fig. 1, or this may be effected by an arm or arms formed for laying
hold of said pipe c in contact with which it is forced by the spring h, while the
air-pump may be either of the common kind used by cyclists for inflating the
pneumatic tyres of their wheels, or other classes of air pumps, or means for
supplying a current of air under pressure may be employed as will readily be
understood.
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 :-
+
The means herein described whereby air under pressure may be employed
for cleaning tobacco pipes substantially as set forth.
