Year: 1867

page_text: LETTERS PATENT to George Walter MacGeorge, of Pimlico, in the
County of Middlesex, Civil Engineer, for the Invention of "IMPROVEMENT3
IN PIPES FOR SMOKING."
Sealed-the 17th March 1868, and dated the 23rd September 1867.
PROVISIONAL SPECIFICATION left by the said George Walter MacGeorge
at the Office of the Commissioners of Patents, with his Petition, on the
23rd September 1867.
I, GEORGE WALTER MACGEORGE, of Pimlico, in the County of Middlesex,
Civil Engineer, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN PIPES FOR SMOKING," to be as follows:-
I insert in the bowl of the pipe used for smoking what I call a partition
bowl or cup abutting at its upper edge against the junction of the inner bowl,
which contains the matter to be smoked and the outer bowl or case to which
the stem of the pipe is attached. There is thus formed under the bowl
containing the matter to be smoked (which bowl has also an aperture at the
bottom) a receptacle for the oil or oils disengaged from the matter to be
[Price 8d.1

page_text: smoked, and between the outer and central partition bowl a receptacle for the
moisture from the mouth. The bowl containing the matter to be smoked may
be attached permanently at the upper part to the outer bowl which carries the
stem (if desired both may be made in one piece and of clay or any other
suitable material), and the partition bowl can be removed from both, so that
the moisture from the mouth and the oil or oils may as often as desired be
readily removed.
This Invention may be carried out in various other ways; thus I sometimes
form the stem and only a portion of the outer bowl in one, the remaining
portion of the outer bowl being attached to the bowl containing the matter to
be smoked; or I let the partition bowl in at the top, in which case the bowl
containing the matter to be smoked would be removeable from the outer bowl.
Among the materials used for the outer bowl, into which the bowl containing the
matter to be smoked is fitted, and also for the partition bowl, papier mache or
papier mache mixed with pulverized charcoal may be employed. When it is
desirable to intercept the moisture wholly or partially in the stem itself I form a
small chamber or receptacle in or attached to the stem, and within this chamber
I place a small quantity of some intercepting material, such as sponge, tobacco,
or a portion of a common cigar; or I insert into the bore at the outer end of the
stem a piece of small tube or piping of silver, glass, or other suitable material,
which tube or piping projects from the stem into an enlargement of the mouth
piece, or into an oblong receptacle of silver, glass, or other suitable material.
At the base of this receptacle and near the stem I make one or more small
openings leading into the mouth piece, which in this case covers the receptacle
into which the above-mentioned tube projects, and is attached to the stem
in the ordinary way; or I close the stem at any convenient part by a small
plug. On that side of this plug which is towards the mouth I bore a hole
leading into a spiral or other groove formed on the outside of the stem; at the
other extremity of this groove I form an aperture opening into the stem of
the pipe on that side of the plug which is towards the bowl of the pipe. Round
this groove and fully enclosing it is fixed a ring or band of metal or other
suitable material. An air-tight connection is thus formed between the parts
of the stem which are at the different sides of the
a greater or less extent intercepted.
plug, and the moisture to

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WALTER MACGEORGE, of Pimlico, in the County of Middlesex, Civil Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of September, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said George Walter MacGeorge, Her special licence that I, the said George
Walter MacGeorge, my executors, administrators, and assigns, or such others
as I, the said George Walter MacGeorge, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN PIPES FOR SMOKING," upon the condition (amongst others)
that I, the said George Walter MacGeorge, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Walter MacGeorge, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:
These improvements in pipes for smoking comprise the following particu-
lars I insert in the bowl of the pipe what I term a partition bowl or cup
abutting at its upper edge against the junction of the inner bowl (containing
the matter to be smoked) and the outer bowl or case to which the stem of the
pipe is attached, which partition bowl or cup should have one or more holes
through its upper part. Under the bowl containing the matter to be smoked
(which bowl also has an aperture that is however situate at the bottom
thereof) there is thus formed a receptacle for the oils disengaged from the
matter to be smoked, and between the outer and the central or partition
bowls a receptacle for moisture from the mouth. The bowl containing the

page_text: matter to be smoked may be attached permanently at the upper part to the
outer bowl which carries the stem (if desired both may be made in one piece
of clay or any other suitable material), and the partition bowl can be remove-
able from both, so that the moisture from the mouth and the oil or oils may
as often as desired be readily removed.
This Invention may be carried out in various other ways; thus I sometimes
form the stem and only a portion of the outer bowl in one, the remaining
portion of the outer bowl being attached to the bowl containing the matter to
be smoked; or I let the partition bowl drop in from the top (in which case the
bowl containing the matter to be smoked, if of clay, is by preference cemented
or otherwise fastened into a rim of wood or other material, and the bowl
containing the matter to be smoked would be removeable from the outer bowl.
Among the materials used for the outer bowl, into which the bowl containing
the matter to be smoked is fitted, and also for the partition bowl papier mache
or papier mache mixed with pulverized charcoal may be employed.
Having thus described the nature of the said Invention, and stated in what
manner the same is to be performed or put in practice, I now proceed further
to describe in what manner the same is to be performed by referring to the
accompanying Drawings by the words, figures, and letters following, that is
to say:
DESCRIPTION OF THE DRAWINGS
and of the detail of the Invention thereby illustrated.
Figure 1, plan view; Figure 2, sectional view; Figure 3, external view.
In the said Drawings the letter A denotes the outer bowl; B, the moveable
partition bowl; B, the apertures at the upper part thereof; C, inner bowl
for holding the substance to be used in smoking; C, aperture at the bottom
thereof; D, D, ring or annular plug into which the inner bowl is fitted and
secured so as to form a rim to the inner bowl; this ring or annular plug thus
securing when pressed or screwed tightly into position the inner bowl in the
outer bowl in an air-tight manner. E, the stem of the pipe, which is shewn in
the Drawing as a removeable one; but it could be made all in one piece with
the outer bowl.
Having now. particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I hereby declare
that I claim the Invention of improvements in pipes for smoking comprised
in the adoption of an outer bowl as usual, and a partition or partition bowl or
receptacle for the oils disengaged in smoking (the same being provided with
an aperture or apertures for the smoke), and an inner bowl for containing the

page_text: substance to be used for smoking, also provided with an aperture or apertures
for the smoke, as herein-before set forth and described, whereby the disen-
gaged oils are deposited in the partition bowl or receptacle and kept separated
from any saliva from the mouth which may find its way into the stem or outer
bowl.
In witness whereof, I, the said George Walter McGeorge, have here-
unto set my hand and seal, this Twenty-first day of March, One
thousand eight hundred and sixty-eight.
