PROVISIONAL SPECIFICATION.
Improvements in or relating to Tobacco-pipes and the like.
We, DONISTHORPE SAVAGE of 137 New North Road, in the County of Middlesex,
Tobacconist, and JOHN MASTERS of 175 Goswell Road, in the County of Middlesex,
Brush Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to tobacco-pipes and the like, its object being the
construction of a pipe or cigar-holder in which a liner or cup of a special kind is
employed in the bowl or body to cause the smoke to traverse a circuitous path in
order to become cooled and to deposit its heavier constituents before it reaches the
mouth piece.
Conveniently the liner comprises two portions one of which is coned or lipped
or flanged to bear upon the outer end of the bowl or body, and preferably screw-
threaded to engage with corresponding screw-threads therein; the second part is
attached to the first part, preferably by screw-threads or other means whereby its
ready detachment therefrom is made possible. Between the two parts are
circuitous channels, formed in the walls of both or of either, and communicating
at one end with the space in which the tobacco is burnt and at the other end with
an opening in communication with the bore of the stem or mouth-piece.
In one construction according to this invention the outer part of the liner has
an annular lip at its upper end extended into an annular groove or channel in the
inner part, and the two parts are kept in connection by screw threads at the lower
ends of each.

Improvements in or relating to Tobacco-pipes and the like.
We, DONISTHORPE SAVAGE of 137 New North Road, in the County of Middlesex,
Tobacconist, and JOHN MASTERS of 175 Goswell Road, in the County of Middlesex,
Brush Manufacturer, 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 tobacco-pipes and the like, its object being the
construction of a pipe or cigar-holder in which a liner or cup of a special kind is
employed in the bowl or body to cause the smoke to traverse a circuitous path in
order to become cooled and to deposit its heavier constituents before it reaches the
mouth piece.

page_text: Conveniently the liner comprises two portions one of which is coned or lipped
or flanged to bear upon the outer end of the bowl or body, and preferably screw-
threaded to engage with corresponding screw-threads therein; the second part is
attached to the first part, preferably, by, screw threads or other means whereby its
ready detachment therefrom is made possible. Between the two parts are
circuitous channels, formed in the walls off both. or of either, and communicating
at one end with the space in which the tobacco is-burnt and at the other end with
an opening in communication with the bore of the stem or mouth-piece.
In one construction according to this invention the outer part of the liner has
an annular lip at its upper end extended into an annular groove or channel in the
inner part, and the two parts are kept in connection by screw threads at the lower
ends of each.
In the accompanying drawings
Figure 1 is a perspective view partly in section of one form of pipe constructed
according to this invention.
Figure 2 a perspective elevation of the body of the pipe shown in Fig. 1.
Figure 3 a similar view of the liner of the pipe shown in Fig. 1.
Figure 4a perspective view partly in elevation of, another form of pipe
constructed according to this invention and
Figures 5 and 6 perspective elevations of portions forming, when placed together,
the liner of the pipe shown in Fig. 4.
Like letters indicate like parts throughout the drawings.
A is the bowl or body of the pipe, screw-threaded upon its interior near its
upper edge as at A'. B is the liner or cup hereinbefore reférred to, in the cavity
or bowl B¹ of which the tobacco is placed and burnt, and which is of such a length
as to leave some space A+ between its bottom and the bottom of the bowl A. On
the exterior of the liner B are cut or otherwise formed channels B³ which follow
a lengthy and circuitous course. The liner shown has two such channels each of
which traverses approximately a semi-circumference of the liner; in Fig. 3 the
liner is shown in such a position as to exhibit the full course of one of these
channels, the other being precisely similar and hidden from view by the body of
the liner.
Communication is established between the cavity B and one end of each of the
channels B; by two holes B³, one hole only being visible in Fig. 3. These holes pierce
the lateral wall of the liner at or near the level of the bottom of the cavity B¹.
The other end of each channel terminates as at B where the channel B³ extends
to the bottom of the liner B.
is
The liner is provided with a screw-threaded portion Be of slightly larger diameter
than its lower portion and a flange B³, the screw threads B being adapted to engage
with the screw-threads A¹ of the body A, and the flange B serving both to afford
a hold upon the liner to enable it to be withdrawn and to form a shoulder limiting
the distance to which the liner enters the body A. The interior of the body A ís
shaped so as to closely fit the liner B, its walls thus forming a cover to the
channels B which are in this manner practically converted each into a duct with
continuous walls closed except at each end where the communications B3 and B+
herein before referred to are open.
It is obvious that smoke being drawn into the mouth-piece A³ leaves the bowl B₁
of the liner by the holes B and, after traversing the ducts B emerges at B* into
the interior of the body A and so passes out of the hole A*:
Instead of two channels B we may employ more, or only one as shown in Fig. 6;
each channel communicating at its one end with the internal cavity of the liner
and at its other end with the cavity between the liner and the body of the pipe.
In the modification illustrated in Figs. 4, 5 and 6 we form the liner in two
parts B and C, the outer portion C being preferably. secured to the inner one B by
screw threads B', which engage with each other, as in the example shown; or
the outer portion C may be made to fit tightly upon the pièce B or secured in any
other manner convenient. Instead of forming a screw thread upon the upper part

page_text: of the inner portion B to engage with the screwed part 'A' of the bowl A, we may,
when the liner is thus formed of two parts, form an external screw thread on the
upper part of the outer piece C and form the screwed part A' correspondingly to
fit as clearly shown in Fig. 4.
In either of the constructions herein before described we may dispense with
screwing a portion of the bowl A as at A', the piece B or the piece C, being made
to fit tightly into the body A without screwing.
A channel or channels similar to those shown at B2 may be formed if preferred
in the substance of the body A on the interior of the same, in which case the
piece B would form the cover to the channel or channels just as the wall of the
body A in the example illustrated covers the channels in the piece B; the piece B
in this case may be made either smooth on the outside or with a channel or channels
to correspond with those in the wall of the body or bowl A.
We do not confine ourselves to the exact form of channel illustrated in the
accompanying drawings but may, in place of the channel having rectangular bends,
employ one consisting of vertical portions united by curved portions in the place
of the horizontal ones illustrated; the chief point in connection with the channel
employed by us being that it shall cause the smoke to ascend to, or nearly to the
top of the liner B and then descend, the outlet being at or near the top of the lower
end of the liner; this ascent and descent may be effected either once or several
times, it is obvious that the above constructions involve a bowl A of much the
usual form.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we claim
is:―
1. A tobacco pipe or the like having a liner such as B between which and the
interior of the bowl or a sleeve such as C is a circuitous channel such as B2 leading
at one end into the cavity of the liner and at the opposite or outlet end B to the
lower part of the cavity of the bowl substantially as described.
2. A tobacco pipe or the like having a liner of the kind described in which the
outlet portion B of the channel is situate near the lower end of the liner.
3. In a tobacco pipe or the like of the kind claimed in Claim 1 a circuitous
channel so shaped that it leads the smoke up and down in substantially the manner
described before exit.
4. In a tobacco pipe or the like the combination of a liner B and sleeve C
separable but making joint with each other and the bowl substantially as described.
6. The complete tobacco pipe substantially as described and illustrated in
Figures 1, 2, and 3 or Figures 4, 5 and 6 of the accompanying drawings.
