Year: 1879

page_text: LETTERS PATENT to Henry Blake Smart, of 28, Edith Road, Peckham, in the
County of Surrey, for the Invention of "IMPROVEMENTS IN PIPES FOR
SMOKING TOBACCO."
Sealed the 6th April 1880, and dated the 9th October 1879.
PROVISIONAL SPECIFICATION left by the said Henry Blake Smart at the
Office of the Commissioners of Patents on the 9th October 1879.

A short stem is made with the bowl of the pipe bored through into the bowl to
its greatest capacity; the inside of the bowl has no bottom, the long stem runs right
through the shorter one to the wall of the bowl, forming the inside bottom of the
pipe; this stem also is bored throughout to its greatest capacity, and a draft hole
is made in the same right through at a point to correspond with about the centre of
the boring of the bowl. By this means the fowling or choking of the bowl is pre-
vented, and by a withdrawal of the stem any deposit therein is at once removed by
blowing or otherwise on account of the free passage through it.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Blake Smart in the Great Seal Patent Office on the 9th
April 1880.

"IMPROVEMENTS IN PIPES FOR SMOKING TOBACCO."
This Invention consists of improvements in pipes for smoking, and has for its
object a ready means of cleaning and preventing the fouling of tobacco pipes and
cigar tubes.
To carry out my Invention a short stem is made with the bowl of the pipe bored
through into the bowl to its greatest capacity; the inside of the bowl has no bottom,

page_text: the long stem runs right through the shorter one to the wall of the bowl forming
the inside bottom of the pipe, and in my Provisional Specification I state that this
stem also is bored throughout to its greatest capacity; the draft hole is made in the
same right through at a point to correspond with about the centre af the boring of
the bowl; by this means the fouling or choking of the bowl is prevented, and by a
withdrawal of the stem any deposit therein is at once removed by blowing or
otherwise on account of the free passage through it, but since the date of such
Provisional I have discovered a more efficient mode of carrying out my Invention,
as hereafter described.
And in order that my said Invention may be readily understood I will proceed
to describe the same with reference to the annexed Drawings, wherein similar
letters of reference indicate similar parts in all the Figures.
Fig. 1 is a longitudinal section of my improved tobacco or smoking pipe, and
shews the same with the parts in position ready for use.
Fig. 2 is a longitudinal section of the part of the pipe consisting of the bowl
and short stem in one piece with it.
Fig. 3 is a side elevation of the long stem or spindle with the mouth piece
attached, the latter being in section.
Attached to the bowl a, and in one piece with it, is a short stem b, which is
bored to the greatest capacity consistent with its size so as to be fully equal in
dimensions to the inside bottom of the bowl. Into this is fitted a long stem or
spindle c, the bowl end c¹ of which is as large as may be, as the inside bottom a¹
of the bowl a, and so forms when in position a kind of false bottom to it. Between
this end c and the collar end c² that screws into the mouth piece d the screw or
spindle is reduced in diameter, as shown at c, so that when in position in the short
tube an annular cavity e is formed round it between the same and the short
stem b attached to the bowl. In the passage of the smoke from the bowl a to the
mouth piece & all the obnoxious deposits are readily trapped or received in the
cavity c, and the fouling of the bowl is thereby prevented. By withdrawing
the long stem or spindle c the deposits in the cavity e can at once be easily and
rapidly removed by blowing or otherwise through the large free passage in the stem
of the bowl. There are grooves c³, c³, in the end c¹ for the passage of the smoke
from the bowl to the cavity e, also a deep groove through the collar and screw
at the mouth piece end for the smoke to pass from the cavity to the mouth
piece.
These improvements are also applicable to cigar tubes.
Having thus described my said Invention, and the manner of carrying the same
into effect, I declare that what I claim, and desire to be secured to me by the
herein before recited Letters Patent is,-
1st. The general arrangement and combination of parts together forming my
improvements in pipes for smoking, substantially as herein before described and
shewn on the Drawings.
2nd. The novel form, shape, and arrangement of the stem or spindle in combina-
tion with the peculiar boring of the bowl of a pipe or cigar tube, substantially as
hereinbefore described and shewn on the Drawings.
In witness whereof, I, the said Henry Blake Smart, have hereunto set my
hand and seal, this Ninth day of April, in the year of our Lord One
thousand eight hundred and eighty
