Year: 1876

page_text: LETTERS PATENT to Benjamin Joseph Barnard Mills, of the Firm of Harris
and Mills, of 23, Southampton Buildings, in the County of Middlesex, Patent
Agent, for the Invention of "IMPROVEMENTS IN SMOKING PIPES." A communi-
cation from abroad by Robert S. Manning, of Trenton, in the County of Mercer
and State of New Jersey, in the United States of America.
Sealed the 22nd August 1876, and dated the 11th April 1876.
PROVISIONAL SPECIFICATION left by the said Benjamin Joseph Barnard
Mills at the Office of the Commissioners of Patents on the 11th April 1876.
BENJAMIN JOSEPH BARNARD MILLS, of the Firm of Harris and Mills, of 23,
Southampton Buildings, in the County of Middlesex, Patent Agent. "IMPROVE-
MENTS IN SMOKING PIPES." A communication from abroad by Robert S. Manning,
of Trenton, in the County of Mercer and State of New Jersey, in the United States
of America.
The Invention consists in constructing a smoking pipe with a double stem, the
inner member on which the mouth piece is formed extending within the main
stem of the pipe as far as the bowl, and being channelled so as to receive and collect
oil and other liquid matter, which when the inner stem is turned within its socket
may be removed from the groove through a slot in the under part of the main stem
of the pipe.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Benjamin Joseph Barnard Mills in the Great Seal Patent Office on
the 10th October 1876.

of the pipe.
And in order that the said Invention may be more clearly understood and
readily carried into effect, I will proceed, aided by the accompanying Drawings,
more fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section of a pipe illustrating the Invention.
Figure 2 is an under side view with the mouth piece and inner stem removed.
Figure 3 is a transverse section on the line 3, 3, Figure 1.
Figure 4 is a view of the inner stem and mouth piece detached.
Figure 5 is a longitudinal section of a pipe having a curved stem.
A, represents the main stem of the pipe, and B the bowl. The latter may be of
common form, and communicates with the stem through a small aperture b. In
the under side of the stem A is formed a longitudinal slot a extending from a point
under the aperture b nearly to the extremity of the stem. C represents an inner
stem on which the mouth piece C is formed, or to which a separate mouth piece of
any preferred shape or material may be applied.
The smoking aperture c is made in customary manner within the mouth piece and
is turned upward as shown at d within the main stem A. so as to communicate
with the interior of the said stem. The inner stem C is constructed with a groove
D extending from a point in front of the inner orifice d of the mouth piece to a
point beneath the orifice b of the bowl. The said groove constitutes a pocket for
containing oil and liquid matter which is collected from the smoke. If preferred,
the orifice d of the stem may open into the groove D in a longitudinal direction,
as shown in Figure 5.
The operation is as follows:-While the parts are in the position shown in
Figures 1 and 3 an air-tight duct is afforded for the smoke from the bowl B,
through the orifice b, groove D, stem A, and orifice d, to the discharge orifice cof
the mouth piece; the groove D constituting an enlarged chamber through which
the smoke passes, causing a deposit of oil and other liquid matter from the sinoke
in a manner which is common with many improved forms of smoking pipes..
As often as may be desirable this liquid matter may be removed with the greatest
readiness by simply turning the inner stem C within its socket in the main pipe
stem A, so as to expose the groove D through the slot a of the pipe stem.
As a modification of the Invention, the pipe may be made with the inner part
of the inner stem of semi-cylindrical form, so that the slot a may be closed or
opened as required by a simple inversion of the inner stem without employing a
groove or pocket therein; or an inner stem or a simple slide of any shape may be
employed, which will close the slot a when in position, and will open it when drawn
out; but it is preferred to construct the pipe with a pocket or oil receptacle D, in
substantially the manner herein described and represented.
Having thus described the nature of the said Invention, and the mode in which
the same is carried into effect, I would have it understood that what I claim is-
First. The pipe constructed with a longitudinal slot a in the stem, and with a
plug C inserted within the stem to close the said slot, substantially as shown.
Second. The plug or inner stem C constructed with a groove D in combination
with the pipe A, B, constructed with a longitudinal slot a in its stem, substantially
as and for the purposes set forth.
In witness whereof, I, the said Benjamin Joseph Barnard Mills, have hereunto
set my hand and seal, this Tenth day of October, in the year of our Lord
One thousand eight hundred and seventy-six.
