IMPROVEMENTS IN PIPES FOR SMOKING TOBACCO
Year: 1876

page_text: LETTERS PATENT to Murray Oliver Camroux, of Richmond, in the County of
Surrey, and Joseph Quick, junior, of Great George Street, in the City of
Westminster, for the Invention of "IMPROVEMENTS IN PIPES FOR SMOKING
TOBACCO."
Sealed the 29th December 1876, and dated the 7th October 1876.
PROVISIONAL SPECIFICATION left by the said Murray Oliver Camroux and
Joseph Quick, at the Office of the Commissioners of Patents on the 7th October
1876.
MURRAY OLIVER CAMROUX, of Richmond, in the County of Surrey, and JOSEPH
❝ IMPROVE-
QUICK, junior, of Great George Street, in the City of Westminster.
MENTS IN PIPES FOR SMOKING TOBACCO."
This Invention has for its object the improvement of pipes used for smoking
tobacco, whereby the expenditure of tobacco is decreased, while the smoke inhaled
is less pungent and more agreeable to the palate than when drawn from pipes as
ordinarily constructed.
The improvements consist in making, fixing, or inserting the stem into the bowl
of the pipe much nearer the top than is usual, and providing the bowl with a piston
or plunger so arranged that by the turning of a screw, applying pressure to a stud
or knob, or by other suitable mechanical device, the said piston or plunger may be
raised or lowered at pleasure. The bowl may be made also with a removable
bottom, so that the piston or plunger may be taken out and cleaned whenever
necessary.
The pipe is used as follows:-The piston or plunger is drawn down to the bottom,
the pipe is then charged with tobacco, lighted, and the smoke inhaled. As the
tobacco is consumed and its surface becomes nearer the stem the piston or plunger
is from time to time to be raised so as to bring up the lower portion of the tobacco
within the draught. By these means the whole of the tobacco may be consumed
without compelling the smoke drawn from the middle and latter part of the charge
to pass through it when soddened with the essential oil produced by the act of

subjecting himself to some of the attendant unpleasantries consequent upon
smoking from pipes as now made.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Murray Oliver Camroux and Joseph Quick, junior, in the Great Seal
Patent Office on the 4th April 1877.
MURRAY OLIVER CAMROUX, of Richmond, in the County of Surrey, and JOSEPH
QUICK, junior, of Great George Street, in the City of Westminster. " IMPROVE-
MENTS IN PIPES FOR SMOKING TOBACCO."
This Invention has for its object the improvement of pipes used for smoking
tobacco, whereby the expenditure of tobacco is decreased, while the smoke inhaled
is less pungent and more agreeable to the palate than when drawn from pipes as
ordinarily constructed.
The improvements consist in making, fixing, or inserting the stem or making the
draught hole in the bowl of the pipe much nearer the top than is usual, and
providing the bowl with a piston or plunger so arranged that by the turning of a
screw, applying pressure to a stud or knob, or by other suitable mechanical device,
the said piston or plunger may be raised or lowered at pleasure. The bowl may be
made also with a removable bottom so that the piston or plunger may be taken out
and cleaned whenever necessary.
In order that the foregoing may be more easily understood Drawings are
attached hereto, of which the following is a description :-
Fig. 1 is a side elevation, Fig. 2 a section showing the plunger A. in the position
it would assume when the bowl B is fully charged with tobacco; Fig. 3 is a similar
section, with the plunger in the position it would take when the charge of tobacco
is nearly smoked out; Fig. 4 a similar section, showing the bowl made with a
removable bottom C.
Fig. 5 shows a modification wherein the stem, though apparently inserted near
the bottom of the pipe, is in reality continued up to nearly the top, and Fig. 6 is a
section of Fig. 5.
In each of the Figures D is the screw by which the plunger A is raised or
lowered, and E a knob, button, or milled head by which the screw is turned. In
either case, if thought necessary, the screw may be dispensed with and a short rod
to support the plunger may be made to simply slide up and down by applying
pressure to the knob E.
The Invention is is no way confined to the outward form shown on the Drawings,
as variations may be made therefrom to suit the taste of the public.
The pipe is used as follows:-The piston or plunger is drawn down to the bottom,
the pipe is then charged with tobacco, lighted, and the smoke inhaled. As the
tobacco is consumed and its surface becomes nearer the stem the piston or plunger
is from time to time to be raised so as to bring up the lower portion of the tobacco
within the draught. By these means the whole of the tobacco may be consumed
without compelling the smoke drawn from the middle and latter part of the charge
to pass through it when soddened with the essential oil produced by the act of
smoking. The smoker has thus an opportunity of indulging in a luxury without
subjecting himself to some of the attendant unpleasantries consequent upon smoking
from pipes as now made.
Having now described and particularly set forth the nature of this Invention,
and the manner in which the same is or may be used or carried into effect, we
would observe in conclusion that we do not confine or restrict ourselves to the
precise details or arrangements which we have described or referred to, as variations
inay be made therefrom without deviating from the principles or main features of

page_text: this Invention, but what we consider to be novel and original and therefore claim
as the Invention secured to us by the herein-before in part recited Letters Patent
is, the construction of tobacco pipes furnished with a piston or plunger which can
be raised or lowered by a screw or rod, as herein-before described and shown on the
Drawings.
In witness whereof, I, the said Murray Oliver Camroux, have hereunto
set my hand and seal, this Fourth day of April, in the year of our Lord ·
One thousand eight hundred and seventy-seven.
MURRAY O. CAMROUX. (L.S.)
