A NEW OR IMPROVED CONSTRUCTION OF TOBACCO-PIPE
Year: 1881

of Middlesex, for an Invention of "A NEW OR IMPROVED CONSTRUCTION OF
TOBACCO-PIPE."
PROVISIONAL SPECIFICATION left by the said Henry Woodward at tho
Office of the Commissioners of Patents on the 16th August 1881.
HENRY WOODWARD, of Shepherd's Bush, in the County of Middlesex. "A
NEW OR IMPROVED CONSTRUCTION OF TOBACCO-PIPE."
My Invention relates to a new or improved construction of tobacco pipe, and in
accordance therewith the bowl is turned hollow and is closed by the stem which is
removeable, and which is fitted into the top thereof instead of into the bottom as
in pipes now in use, so that the bowl depends from the stem.
The opening into which the stem is screwed or otherwise fitted serves as the
mouth of the bowl through which the tobacco is introduced when the stem is
detached.
At or about the lower part of the bowl I provide two or more upwardly inclined
orifices communicating with the interior thereof, and to any of these orifices the
flame is applied, and is drawn in the usual manner when the pipe is to be lighted,
the tobacco burning upwards instead of downwards. These orifices also serve as
passages through which the air necessary to support combustion enters.
If desired a plug or plugs secured by a chain or chains may be provided to close
any of the orifices.
The stem which, as before stated, is fitted into the top of the bowl is furnished
with a perforated metal tube, closed at its lower end, and extending to nearly the
bottom of the bowl. The bottom of this tube is cut off at an angle and forms a
sharp edge, whereby the passage of the tube through the tobacco is facilitated.
The smoke drawn from the tobacco passes through these perforations into the stem,
and thence into the mouth of the smoker.
By constructing the pipe in the manner set forth the nicotine and other solid
products of the tobacco are consumed, and are thus prevented from entering the
mouth of the smoker; and as the tobacco burns upwards the entire charge is
consumed and remains dry to the very last whiff. The ashes from the tobacco aro
retained in the bowl, so that it is only necessary to remove the stem to empty the
bowl of same prior to reloading the pipe.

by the said Henry Woodward in the Great Seal Patent Office on the
14th February 1882.
HENRY WOODWARD, of Shepherd's Bush, in the County of Middlesex. "A
NEW OR IMPROVED CONSTRUCTION OF TOBACCO PIPE,"
My Invention relates to a new or improved construction of tobacco pipe in
which the bowl instead of being left open, as in pipes hitherto in use, is closed at
top by its stem and depends therefrom, the tobacco in the bowl being ignited or
fired through an orifice or orifices contrived for the purpose at or about the lower
part of the said bowl.
In the accompanying Drawings, Figure 1 is a side elevation of a pipe constructed
in accordance with my Invention; and Fig. 2, a detailed view of the various parts
constituting the same, and shewn partly in sectional elevation.
A is the bowl; it is turned hollow, and is provided with an opening a at top
forming the mouth or entrance through which the tobacco is introduced. This
bowl is formed at its upper part with a rebato a¹ which is scrow threaded out-
wardly to receive an inwardly screw threaded ivory or vulcanite ring b. The
lower portion of this ring fits on to the rebate a', and into its upper portion the
stem B is screwed; but the stem may be otherwise secured to the bowl, as for
example, by a bayonet joint arrangement.
C is a downwardly inclined orifice contrived at or about the lower part of the
bowl, and communicating with the interior thereof; it is protected by a thin metal
plate c. This orifice serves a two-fold purpose, the first being that it answers as
the vent through which the flame is communicated to the tobacco and is drawn in
the usual manner, the tobacco when ignited burning upwards; and the second,
that it serves as a passage through which the air necessary to support combustion
enters. There may be another of these orifices if desired, and it may be situated
diametrically opposite to the first named one, or otherwise as found necessary;
either may be provided with a plug attached by means of a chain to the stem, but
in practice I prefer to construct the pipe with only one such orifice, and without
any plug.
A washer or plate d of ivory, asbestos, or other non-conductor may be secured
to the underside of the stem to prevent said stem becoming heated. An ivory
ring may also be interposed at any suitable part of the stem, if required, for the
same purpose, as for example at g.
The bowl may be constructed of wood, clay, meerschaum, or china, and of any
desired shape.
Fig. 3 shews a modified arrangement of stem provided with a perforated metal
tube D. This tube is closed at its lower end, and extends to nearly the bottom of
the bowl; it is cut off at an angle, as shewn, so as to form a sharp edge in order
to facilitate its ready passage through the tobacco. The smoke as drawn from the
tobacco passes through the perforations in this tube, and thence into the mouth of
the smoker.
Fig. 4 shews an arrangement in which a straight instead of a curved stem is
used. This stem, as well as the bowl, may be made of briar, cherry, or other wood,
or of meerschaum or other suitable substance.
By constructing the pipe in the manner above set forth the nicotine and other
like solid products of the tobacco are consumed, and therefore do not enter the
mouth of the smoker; and as the tobacco burns upwards instead of downwards the
entire charge is consumed, and both it and the bowl remain dry to the last "whiff."
Furthermore, as the ashes from the burnt tobacco are retained in the bowl during

page_text: smoking, it is only necessary to remove the stern after the charge has been
consumed to empty the bowl of same, or prior to reloading the pipe.
Having now described the nature of my said Invention, and in what manner
the same may be carried into effect, I declare that I claim,―
1. The improved tobacco pipe consisting in the construction and employment of
the bowl closed at top by the stem, from which it depends, and provided at or
about its lower part with an orifice (or orifices) serving as an entrance for the
igniting flame, and for the passage of air to the kindled tobacco, substantially as
herein described and illustrated in the annexed Drawings.
2. The modified arrangement of stem with perforated tube, as herein described,
and the employment of same in combination with the new construction of bowl, as
herein specified and claimed above.
In witness whereof, I, the said Henry Woodward, have hereunto set my
hand and seal, this Twenty third day of January, in the year 1882.
H. WOODWARD. (LS.)
