Improvements in and connected with Tobacco Pipes.
HARRY FREDERICK HILL I Allan Terrace Sherwood Street Nottingham (Brass-
founder) do hereby declare the nature of this invention to be as follows:-
Pipes constructed according to this invention are made with an enlarged part in
the centre of the stem this enlarged pari is screwed together giving access to the
interior, a filtering material incased in tin foil is placed in the cavity & the stem
screwed together. A second improvement consists in placing the filter plug in the
howl of the pipe. This plug may be made in a slightly altered form by groving the
metal casing on the out-side for the smoke passage & waking the hollow interior a
receptacle for nichertine. These plugs may also be applied to cigar or cigarette
holders. The casing & filtering material may be of any suitable substance.

Improvements in and connected with Tobacco Pipes.
HARRY FREDERICK HILL I Allan Terrace Sherwood Street Nottingham (Brass-
Founder) 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:-
Pipes constructed according to this invention are made with an enlarged part in
the centre of the stem, this enlarged part is screwed together giving access to the
interior. A filtering material encased in tinfoil is placed in the cavity and the stem
screwed together; and in order that the said invention may be better understood I
proceed to explain the same by the aid of the accompanying sheet of drawings.
Figure 1 is an example of one method of application and consists of an outer
easing (1) which is in wood, the stem of which is bored large enough to receive the
inner casing or tube (2.) which is preferably of clay but may be of other material,
the interior of which is filled in with carbon, charcoal or other suitable material (3.)
which is kept in its place by the caps or washers (4.). The imbing (2.) is also
provided with enlarged parts at the ends which keep it in the centre of the casing (1.)
making an equal air-space between the outer casing and inner tube. The mouth-
piece (5.) is also bored large enough to receive the end of the tubing (2.) and the
tube (6.) which is of clay. This enlarged bore down the mouthpiece is continued
to within a short distance of the end as shown in the enlarged drawing (1 a.) the
small end left forming a cap which prevents the tube from falling out. When the
rubber washers (7. 7.) are fixed in their places as shewn the iube (2.) is inserted
and the mouthpiece attached by means of the screwed ferrule (9.). The iube (2.) is
thus made air-tight at the ends thus allowing the outer casing (1.) to be perforated
at the points (S. §. S. 8. S. S.) without making an outlet for smoke. By this means
a current of air is kept circulating round the tube (2.) keeping it dry. An
enlargement of washer (7.) is given at Fig. 1. shewing a small ring of metal or other
hard substance inserted in the centre of the rubber which prevents it gripping the
jube (6.) when requiring to be removed. The clay grating (10.) serves for the
better combustion of the tobacco. The use of the valve (11.) at the end of
the mouthpiece is explained in Fig. 8.
Fig. 2 is a modification in which the tube (2.) is kept in the centre of casing (1)
by means of the projecting edges of the rubber (7.).
A section of the filtering plug
is shown in the bowl of the pipe and consists of an inner bell (5.) within an outer

are so placed as to cause the smoke to make a circuit.
Fig. is another method of making the tube (2.) airtight within the casing (1.)
by the rubber or cork ring (7.) being fitted in the groove made in the outer casing
to receive it, the tube (2.) sliding through it. The same arrangement may be used
for making the opposite end of tube (2.) tight within the mouthpiece. At the end
of the tube (2.) is a valve (9.) which prevents moisture from the mouth passing into
and injuring the filtering material. This valve is shewn enlarged in Fig. 9, which
consists of an inner ball within an outer casing, the ball resting upon a seating with
outlet holes provided in the top side of the casing, shewn at (3. 3. 3.).
Fig. 4 is an arrangement. shewing the iube (2.) carried into the bowl of the pipe
and slightly beyond. The tube (2.) having perforations (3. 3. 3.) upon the surface
forming a clay grating or floor at the bottom of the pipe-bowl. A further improve-
ment consists in forming one or more bridges (4. 4. 4.) within the tubing (2.) having
smoke passages (3. 3. 3.).
Fig. 5 shews the rubber (7.) fitted in a groove of the tube (2.) which tube is
partly formed in the shape of a spiral and may if desired be made spirally the
whole length.
Fig. is a modification in which the spiral (2.) is attached direct to the pipe-bowl
and carried out to form the month-piece and may be made of clay in one piece or
attached separately. The filtering material may be inserted into the spiral through
the bowl of the pipe (3.). The outer casing (1.) for protecting the inner spiral (2.)
in this case is made of thin sheet metal and formed in two halves being held together
by hinges (4. 4.) and when closed, by the fasteners (5. 5.). It will be seen, however.

washer (6.) is stretched over the pipe-bowl or inserted in the casing to prevent the
pipe-head from shaking.
Fig. is a top view of the mouthpiece end shewing the casing closed.
Fig. is a section of mouthpiece of Fig. 6 shewing the method of making the end
of the inner tube air-tight with the outer casing (1) by means of the rubber
washer (7.) which is held in position by the outer casing being turned over forming
a rim (S.) which prevents the rubber being pushed out by the inner tube (2.)
pressing against it.
Fig. 12 is a perspective view of Fig. 6 when closed shewing perforations in the
metal casing.
Fig. S is a method to be used with the casing (1) split down the entire length a
rubber tube (7.) terminating in a cap at one end is streiched over the outer casing at
the end of the mouthpiece; the inner tube (2.) passing through the said cap is made
air-tight to the casing (1.). The clack or valve (9.) attached to the cap or made
in one piece with it is a modification of the valve (9.) shewn in Fig. 3.
Fig. 10 is a modification of Fig. 6. In this case the split metal casing (1.) is
combined with a mouthpiece of amber or other material (5.) similar to those in

is closed the mouthpiece is screwed on thus binding the two halves together, thus
only requiring one hinge (6.) at the top of the bowl. The inner tubing (2.) is made
in one piece with the pipe-bowl, preferably of clay and is made air-tight with the
mouthpiece by means of the rubber (7.). The tubing (2.) has also a bend or trap (8.)
for the collection of nicotine. A space (9.) is shown in the mouthpiece. in which
may be placed a small filter casing.
Fig. 11 is a further modification in which the outer casing (1.) is in one piece
not being split or divided. The inner tube (2.) being attached to a loose pipe-
bowl (3.) by means of the rubber (7.). When desired the tube (2.) may be drawn
out at the mouthpiece end and the bowl withdrawn by removing the screw-cap (6.).
The inner tube is made air-tight to the outer casing by the rubber tube and cap
as in Fig. 8.
Fig. 11 is another method of making tube (2.) tight with the outer casing and
consists in making an enlargement or collar (3.) at the end of tube 2. a rubber

page_text: washer (7.) is stretched over on to the tube the said rubber being pressed into a
recess formed in the end of the mouthpiece.
Fig. 13 is an improved form of grate arrangement for the better combustion of
tobacco and consists in making a shoulder in the bowl of the pipe a distance from the
bottom of the bowl which prevents the grate being forced down too tightly upon
the filter casing which may be placed in the bowl before the grating is put in. The
grate (4.) is also provided with legs which will serve in lieu of a shoulder, or studs
projecting from the inside of the bowl may be used. A stud (3.) is screwed into the
bowl above the grate to make it secure or a spring stud (3.) may be used.
The
grate is made in the form of bars as shewn in the plan 4 and is made in enamelled
metal. The slot (8.) in casing 1 is to enable the washers (7.) as shown in Fig. 8 to
be inserted, this slot being filled in with suitable cement when the washer has been
placed in position.

Fig. 14 is a modification of Fig. 11 shewing the tubing (2.) passed through the
front part of the pipe and made light to the bowl by the washers (7. 7.).
springs (S. S.) are used for keeping the bowl in its place. The inlet holes for smoke
passage are placed downwards which prevents them getting blocked up, a chamber (4.)
being formed below to further prevent the same,
Having now fully described my said invention 1 wish it to be understood that I
do not bind myself to a strict combination of the various parts as herein shewn, but
may interchange them as desired. It must be further understood that the outer
casings in Figs. 6, 10, & 11, are in sheet metal stamped to shape in moulds and
enamelled, or may be made of wood pulp or papier-maché by the same process if
desired. The inner casings or pipes may in some cases be used independently of
the outer casings. I also wish it to be understood that I do not claim the use of
charcoal or other filtering for filtering, but my claims are
(1) The special construction of the new & improved parts for the application &
protection of filtering material as herein set forth & described by the aid of the
accompanying sheet of drawings.
(2) Removable clay or rigid casings or linings made of sufficient length, to project
beyond the stem of the pipe when the mouthpiece is screwed off, with the screwed
ferrule, whereby they are the more easily removed, as or similar to Fig. 1.
(3) Inner tubes with air space around with perforations in the casing as or
similar to Fig. 1.
(4) The construction of pipes having removable linings or casings throughout the
whole length of the stem & mouthpiece substantially as herein set forth.
(5) Rigid inner tubes or casings with flexible tight joints substantially as herein
set forth.
(6) The making of the inner tubes or casings air-tight to the outer casing
hy rubber tubes & cap combined or by rings or tubes only as
or similar to
Figs. 7. 8 & 11.
(7) The construction of a filtering plug for the boul of the pipe by the incertion
of an inner bell or grate within an outer casing as or similar to Fig. 2.
(8) The special construction of inner tubes or casings having ends with reduced
holes caps or bridges as or similar to Figs. 1, 3 & 4.
