IMPROVEMENTS IN TOBACCO-PIPE JOINTS
Year: 1881

page_text: PROVISIONAL SPECIFICATION left by the said William Horton Sharman
at the Office of the Commissioners of Patents on the 8th July 1881.
WILLIAM HORTON SHARMAN, of Highbury, in the County of Middlesex,
Silversmith.. "IMPROVEMENTS IN TOBACCO-PIPE JOINTS."
This Invention relates to improvements in that class of pipes for smoking tobacco
in which the mouth piece is detachable from the bowl.
Hitherto it has been the practice to connect the mouth piece and bowl by means
of a screw joint or a "push in "joint; in the former case the joint possesses the
disadvantage of requiring a comparatively long time in opening and closing the.
same, while in the case of the "push in "joint the parts become worn from frequent
separation, so as to render the joint leaky and loose.
My improvements consist in constructing what I term a slide joint, which is not
liable to the said hereinbefore described inconveniences.
In carrying out my Invention I adapt to the end of the bowl of the pipe a
metal mount of suitable shape and formed with a flanged tapered socket or groove.
closed at one end and at right angles, or thereabouts, to the axis of the pipe stem ;
the end of the mouth piece which fits against the end of the bowl is provided.
with a metal mount formed with a tapered flanged projection of a form to allow it
to slide in the hereinbefore described socket on the end of the bowl of the pipe.
By this construction of joint, the stein and bowl of the pipe can be quickly and
easily fitted together or separated from one another and a tight and perfect joint
be insured.
It will be understood that the socket and projection may be of square, cylindrical,
or other form.

WILLIAM HORTON SHARMAN, of Highbury, in the County of Middlesex,
Silversmith. "IMPROVEMENTS IN TOBACCO PIPE JOINTS."
This Invention relates to improvements in that class of pipes for smoking tobacco
in which the mouth piece is detachable from the bowl.
Hitherto it has been the practice to connect the mouth piece and bowl by means
of a screw joint or a "push in "joint; in the former case the joint possesses the
disadvantage of requiring a comparatively long time in opening and closing the
same, while in the case of the "push in" joint the parts become worn from frequent
separation, so as to render the joint leaky and loose.
My improvements consist in constructing what I term a slide joint which is not
liable to the said hereinbefore described inconveniences.
But to make my Invention better understood I will proceed to describe the same
by reference to the accompanying Drawing, in which similar letters represent
similar or corresponding parts.
In carrying out my Invention I adapt to the end of the bowl part a of the pipe
shewn in detached side elevation at Figure 1, a metal mount 6 formed with a
flanged tapered socket or groove c closed at one end and at right angles, or there-
abouts, to the axis of the pipe stem, as shewn at Figure 2, which is an end view of
the mount b. The end of the mouth piece d, shewn in detached view at Figure 3,
and which fits against the end of the mount b of the bowl part a, is provided with
a metal mount e formed with a tapered flanged projection f, as shewn at Figure 4,
which is an end view of the mount e; the projection being thus formed may be
slid vertically in the socket or groove c on the end of the bowl a of the pipe, as
shewn at Figure 5, which is a side elevation of the pipe complete with the two
parts of the joint fitted together.
Figures 6, 7, 8, 9, and 10 are similar views to those shewn at Figures 1 to 5, but
in this case the pipe joint is formed with a slightly tapered cylindrical projection f
sliding in a correspondingly shaped socket c and in a horizontal direction.
By the hereinbefore described construction of pipe joints, it will be seen that by
sliding the projection f of the joint within the corresponding groove c, the stem
or mouth piece d and the bowl part a of the pipe can be quickly and easily fitted
together or separated from one another, at the same time that a tight and perfect
joint will be insured when the parts are put together.
Having thus described my said Invention and the best means I am acquainted
with. for carrying the same into effect, I wish it to be understood that I do not
confine myself to the precise details herein before described and illustrated in the
accompanying Drawing, as the same may obviously be varied without departing
from the peculiar character of my Invention, as, for example, the socket and
projection may be made of other shapes than those shewn, and the ends of the two
parts of the joint may be inclined, but what I do claim is,―
Firstly. The improved slide joint for tobacco pipes constructed and operating
substantially in the manner and for the purposes herein before described and
illustrated in the accompanying Drawing, or any mere modification thereof.
Secondly. The manufacture and use of tobacco pipes having sliding joints

the accompanying Drawing.
In witness whereof, I, the said William Horton Sharman, have hereto set
my hand and seal, this Thirteenth day of October, in the year of our Lord
One thousand eight hundred and eighty one.
