Improvements in Cos
ROBERT HENRY CAMPBELL 35 Halsey Street, London S.W. Commercial
Traveller 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 :-
The object of my invention is to provide a cheap, simple, and at the same time
a very efficient nichotine trap adaptable to all kinds of tobacco pipes togather
with mouthpieces for the saine.
The first part of my invention will relate to nichotine traps these are caps
which screw or clip or slide on the tube and sleeve principle on or over the nipple
or end of the stem or mouthpiece. I accordingly make a hollow cap open at one
end and closed at the other end with the exception of one or two or more holes
which I make on the closed end of the cap to admit of the smoke entering the
mouth of the smoker as the position of these holes on the closed end of the cap
forms an important part of my invention I shall proceed to explain their position
thereon as plainly as possible but before doing so I will explain the drawings.
Fig. 1 shows a stem or mouthpiece having a hollow nipple attached to it by
means of a narrow screw at the end.
Fig. 2 shows a stem or mouthpiece without the nipple at the end and having a
hollow nipple attached thereto by means of a tube or sleeve.
Fig. 3 shows a stem or mouthpiece having the screw at the end large and the
hollow nipple rising with a second shoulder from the mouthpiece.
Fig. 4 shows a stem or mouthpiece having a nipple or bulge at the end and the
hollow cap just catching on the nipple.
Figs. 5-6 and 7 shows the position of the holes on the upper half of the closed
end of the cap.
Fig. 8 shows a cap having instead of a hole or holes a incision or cut made on
the upper half and countered in.
Fig. 9 shows a cap having a sliding collar on the tube or sleeve.
Fig. 10 shows the incision or cut extending from the open end of the sleeve.
Fig. 11 shows a cap having the under half of the closed end fuller in size than
the upper half.
Fig. 12 shows a cap having the second well or receptacle situated on the under
part of the sleeve.
Fig. 13 shows one means of attaching the cap to the stem or mouthpiece
Fig. 14 another way and Fig. 15 shows the end of the stem or mouthpiece.
narrowed down to take the sleeve of the cap.
Fig. 16 shows a stem or mouthpiece having a hollow or groove on the
under side.
Fig. 17 shows a stem or mouthpiece covered at the end with plain corkwood or
indiarubber and Fig. 18 shows the same covered with corrugated rubber or
corkwood.
Fig. 19 shows a stem or mouthpiece having the nipple or bulge attached to the end
in a way I shall hereafter explain. A is the screw at the end of the mouthpiece
B is the washer shaped piece of indiarubber or corkwood which passes over the
screw and C. is the nut which holds it fast thereon.
Fig. 20 shows a stem or mouthpiece having the under half A fuller in size than
the upper half.
. When I make the cap with one hole I place the hole near to the top of the cap.,

page_text: so that it may be above the level of the smoke passage of the pipe or I may
place the hole in a more or less degree on the right or left side of the cap. Again
when I make the cap with two holes I place they holes in a more or less degree on
the right and left sides of the cap that is one hole on the right side and one on
the left side but when I make the cap with three or more holes I reduce the size
of the holes and distribute them in any suitable position over the upper half of
the cap. All the holes are situated on or above the centre of the closed end so as
to admit of the under half of this end to form a well or receptacle this half is
made in two sizes first of equal or uniform size with the upper half or according
to another way I make the under half or well portion fuller in size than the part
where the holes are situated, when the caps are made with one or two or three holes
they holes are countered in from the outside or they may have a ring or bead
extending round or partly round them they may likewise have a ring or bead
extending round or partly round them, on the inside of the cap. At the open end
of the cap there is a flange or groove or the flange may mearly take the form of
a bead this bead or groove extends either in whole or in part round the inside of
the cap, in addition to the above mentioned flange or groove there may be a
second flange or groove extending round or partly round the inside of the cap
this flange or groove is situated near to that part of the cap which forms the well
and has for its object the prevention of nichotine getting between the barrel or
clip portion of the cap and the stem of the pipe.
In formation these caps takes the form of a tube or sleeve made to fit any make
of stem or mouthpiece in length this tube or sleeve varies from one sixteenth part
of an inch up to one inch or more the closed end of the cap takes the form of an
nipple or bulge of round or oval formation and rises with a round or sharp set
shoulder from the part forming the tube or sleeve. When the cap is made with a
tube or sleeve of a certain length that is of about a quarter of an inch or more
I may be able to make the cap fit secuarly to the end of the stem or mouthpiece
without the aid of the bead or groove on the inside of the open end therefore
I claim the right and as part of my invention to make a hollow cap to fit onto the
end of the stem or mouthpiece with or without the bead or groove on the inside of
the open end.
According to another way I make a cap in every respect like unto the before
mentioned cap but having in addition a sliding collar on the tube or sleeve and a
bead extending round or partly round the sleeve at or near to the open end on the
outside.
According to another way I make a cap in every respect like unto the first
and before mentioned cap but having in addition a second chamber or well
running from or communicating with the first well or that part of the cap which
forms the under half of the nipple or bulge to do this I make a hollow or groove
on the under part of the sleeve of the cap or on the under part of the stem or
mouthpiece as is shown in Figs. 12 and 16 of the drawings this hollow or groove
runs into a short pipe on the outside of the under part of the sleeve to this short
pipe I attach by a screw or other suitable means a well or receptacle of suitable.
shape or design.
When these caps are made from material that will not fit perfectly to the stem
or mouthpiece I may prepare the inside of the cap in such a way and with such
material as will insure a perfect fit or I set the cap in a tube or teat of indiarubber
this tube or teat may extend in length beyond the full length of the cap. When
the caps are made from material of a hard or unpliable nature or when the stem
or mouthpiece is not prepared to fit the cap in a way I shall explain in my
specification for mouthpieces I then make one or more incisions or cuts in the
sleeve running lengthwise from the open end.
According to another form of cap I make the end of the stem or mouthpiece
by moulding or otherwise into a screw or for the same purpose I may insert a
screw into the end of the stem or mouthpiece above this screw there is a flange
or again I form by moulding or otherwise the end of the stem or mouthpiece into

page_text: a round flange the face of this flange is hollowed in making the end of the stem.
or mouthpiece take a concave form with the smoke passage juting out in a short
tube in the centre the outer edge or rim of this flange takes the form of a screw
with a stop flange on the inner edge to both these ways I attach by means of the
screws a hollow nipple or bulge to the end of the stein or mouthpiece this nipple
or bulge will be round or oval in shape and rising with a round or sharp set
shoulder from the stem or mouthpiece it will have one or two or more holes on or
above the centre of the upper half and situated thereon in the same way and
manner as is shown in the first and before mentioned cap or instead of a hole or
holes I may make an incision or cut on the upper half in the way before
described.
The second part of my invention relates to mouthpieces or that part of a
tobacco pipe which forms the end of the stem and the object I have in view is to
prepare the end of the stem or mouthpiece in such a way that it will fit more
perfectly to the cap or nichotine trap there are two ways in which I do this
according to one way I make the stem or mouthpiece without the nipple or bulge
which generally forms the end and I afterwards mount the end of the stem or
mouthpiece with a nipple or flange made in whole or in part of soft or pliable.
material and for this purpose I use indiarubber or corkwood I first reduce by
moulding or otherwise the end of the stem or mouthpiece and I form the reduced
part into a screw to take a nut above where the screw joins the thick part of the
mouthpiece I may make a flange I then pass over the screw a tube or washer
shaped piece of indiarubber or corkwood and make it fast thereto by means of
cement and the nut or I may mount on the end of the stem or mouthpiece a
nipple or flange made from indiarubber or corkwood by means of cement and
without the screw or nut.
According to another way I reduce by moulding or otherwise the end of the
stem or mouthpiece and on the reduced part I put a tube of plain or corrugated
indiarubber or cork and make it fast thereto with cement this form of mouthpiece
is made without the nipple or flange at the end and may gradually taper or
decrease towards the end round this stem or mouthpiece and just above where the
indiarubber or cork joins it at the thick part I make a bead or groove to fit the
bead or groove at the open end of the cap or instead of making a bead on
the mouthpiece I may make the indiarubber or cork to rise at this part above.
the level of the stem ur mouthpiece, these together with the two mouthpieces
hefore described having the screw at the end as shown in Figs. 1 and 3 of the
drawings are what I claim as my invention.
The third part of my invention is improvements in a stem or mouthpiece for
general use and the object I have in view is to prevent the tongue of the smoker
comming in contact with the hole which forms the end of the smoke passage to
do this I make the under half of the nipple or flange which forms the end of the
stem or mouthpiece fuller or larger in size than the upper half as is shown in Fig. 20
of the drawings the hole which forms the smoke passage is placed in the centre
midway between the upper and under halves or I may make the under or fuller
half to extend up so that whilst leaving a free passage for the emoke it may in
part cover the hole, this form of nipple is made by moulding or otherwise on the
end of the stem or mouthpiece or I may make this nipple or flange seperatly and
attach it to the end of the stem or mouthpiece by means of a screw or on the
tube and sleeve principle with a clip or catch. In the manufacture of the caps
which forms the first part of this specification I wish it to be understood that I do
not confine myself to make the face or end of the nipple round or oval only as in
some cases it may be found more expedient to have the face or extreme end made
flat therefore I claim the right and as part of my invention to make a cap in the
ways before described with the face of the nipple round or oval or flat I also
claim as part of my invention the right to have any or all of the before mentioned
caps made with the under half of the nipple or bulge fuler or larger in size than
the upper half or the part where the holes are situated.

page_text: Having now particulary described and ascertained the nature of my said inven-
tion and in what manner the same is to be preformed I declare that what I
claim is
1. A hollow cap made to catch or clip on or over the end of the stem or
*mouthpiece.
2. A hollow cap made to slide on the tube and sleeve principle over the end of
the stem or mouthpiece.
3. A hollow cap made to screw on the end of the stem or mouthpiece in the
way before described and shown in Figs. 1 and 3 of the drawings with stem or
mouthpiece for the same.
4. A hollow cap having a bead or groove extending round or partly round
the inside at or near to the open end.
5. A hollow cap having one or two or more holes situated on the upper half of
the closed end in the way before described.
6. A hollow cap taking the form of a tube or sleeve with the closed end
rising with a round or sharp set shoulder from the tube or sleeve the closed end
being round or oval in shape or taking the form of a nipple or flange and hollow.
7. A hollow cap having a bead or groove extending round or partly round the
inside of the sleeve at or near to the open end.
8. A hollow cap with a tube or sleeve but without the bead or groove on the
inside of the sleeve as before described.
9. A hollow cap having instead of a hole or holes a incision or cut made in the
upper half of the closed end.
10. A hollow cap of which the under half of the closed end forms a well or
receptacle.
11. A hollow cap having the under half of the closed end fuller in size than the
upper half.
12. A cap having a sliding collar on the sleeve.
13. A hollow cap having a second chamber or well communicating with the
first well in the way before described.
14. A hollow cap having the face of the nipple or bulge made round or oval
or flat.
15. A cap which may have one or more cuts made in the sleeve at the
open end.
16. A stem or mouthpiece having the end covered with indiarubber or cork in
the way before described and shown in Figs. 17-18 and 19 of the drawings.
