« IM-
My Invention has reference to the telescopic stems of the said pipes and cigar
holders, and my said Invention consists of the improvements herein-after described
in constructing and arranging the parts of the said stems whereby the advantages
herein-after pointed out are secured.
The telescopic stems of pipes for smoking and of cigar holders are ordinary
composed of a series of metal tubes of different diameters, the tubes sliding into
and out of one another after the manner of the tubes of a telescope. In this con-
struction the oil of tobacco comes into direct contact with the interior of the metallic
telescopic stem and rapidly corrodes the said stem, and if the tubes do not fit with
great accuracy the drawing qualities of the pipe or cigar holder are impared.
Ordinary telescopic stems are also difficult to clean. By my improvements the.
defects referred to in telescopic stems are remedied.
My Invention consists in using in combination with the ordinary telescopic
arrangement of the stem a supplementary tube of vulcanized india-rubber fixed
within the tubular stem, the said internal or supplementary tube constituting the
true channel through which the smoke passes and in which the oil of tobacco is
deposited. One end of the said internal elastic tube is secured to an ivory or other
mount which is fitted in the socket of the pipe'or cigar holder, and the opposite end
of the said elastic tube is secured to a similar mount on the mouth-piece.
The largest tube of the telescopic stem is screwed to the mount which fits in the
pipe or cigar holder socket, and the smallest tube of the stem is screwed to the
mount on the mouth-piece. The said internal or smoke tube is of a length some-
what greater than that of the largest tube of the telescopic stem, and when the said
stem is in its collapsed or shortened state the internal or smoke tube is situated
concentric with the several tubes of the stem.
[Price 6d.1

page_text: When the telescopic stem is expanded or lengthened for use the elastic elastic or
smoke tube is correspondingly lengthened, forming a continuous chanuel from the
wide end of the stem to the mouth-piece at the narrow end of the stem.
When the stem is shortened by the sliding of the tubes within one another the
internal or smoke tube returns to its normal length.
For the purpose of readily connecting the internal or smoke tube to and dis-
connecting it from the stem, for cleaning small-headed tubes, are fixed to the mounts
described at the base of the stem and at the mouth-piece to which headed tubes
the ends of the internal or smoke tube are secured by expanding them over the
heads of the said small tubes and fixing them by fine thread; and for the purpose
of preventing the twisting of the internal or smoke tube and choking the smoke
passage, one of the headed tubes described is made capable of swivelling in the
mount in which it is secured.
By the use of the clastic internal or smoke tube described any imperfection in the
joints of the telescopic stem does not affect the drawing qualities of the pipe or
cigar holder, the smoke and oil of tobacco do not come in contact with the external
metallic telescopic stem and the internal or smoke tube is readily removed, cleaned,
and replaced.

"IM-
My Invention has reference to the telescopic stems of the said pipes and cigar
holders, and my said Invention consists of the improvements, herein-after described,
in constructing and arranging the parts of the said stems, whereby the advantages
herein-after pointed out are secured.
The telescopic stems of pipes for smoking and of cigar holders are ordinarily
composed of a series of metal tubes of different diameters, the tubes sliding into and
out of one another after the manner of the tubes of a telescope. In this construction
the oil of tobacco comes into direct contact with the interior of the metallic
telescopic stem and rapidly corrodes the said stem, and if the tubes do not fit with
great accuracy the drawing qualities of the pipe or cigar bolder are impaired.
Ordinary telescopic stems are also difficult to clean. By my improvements the
defects referred to in telescopic stems are remedied.
My Invention consists in using, in combination with the ordinary telescopic
arrangement of the stem, a supplementary tube of vulcanized india-rubber fixed
within the tubular stem, the said internal or supplementary tube constituting the
true channel through which the smoke passes and in which the oil of tobacco is
deposited. One end of the said internal elastic tube is secured to an ivory or other
mount which is fitted in the socket of the pipe or cigar holder, and the opposite end
of the said clastic tube is secured to a similar mount on the mouth-piece.
The largest tube of the telescopic stem is screwed to the mount which fits in the
pipe or cigar holder socket, and the smallest tube of the stem is screwed to the
mount on the mouth-piece. The said internal or smoke tube is of a length some-
what greater than that of the largest tube of the telescopic stem, and when the said
stem is in its collapsed or shortened state the internal or smoke tube is situated
concentric with the several tubes of the stem.
When the telescopic stem is expanded or lengthened for use the elastic or smoke
tube is correspondingly lengthened, forming a continuous channel from the wide
end of the stem to the mouth-piece at the narrow end of the stem.
When the stem is shortened by the sliding of the tubes within one another, the
internal or smoke tube returns to its normal length.
For the purpose of readily connecting the internal or smoke tube to and dis-

page_text: connecting it from the stem for cleaning small headed tubes are fixed to the mounts
described at the base of the stem, and at the mouth-piece to which headed tubes
the ends of the internal or smoke tube are secured by expanding them over the
heads of the said small tubes and fixing them by fine thread; and for the purpose
of preventing the twisting of the internal or smoke tube and choking the smoke
passage, one of the headed tubes described is made capable of swivelling in the
mount in which it is secured.
By the use of the elastic internal or smoke tubo described any imperfection in
the joints of the telescopic stem does not affect the drawing qualities of the pipe or
cigar holder, the smoke and oil of tobacco do not come in contact with the external
metallic telescopic stem and the internal or smoke tube is readily removed, cleaned,
and replaced.
I will now proceed to describe, with reference to the accompanying Drawing, the
manner in which my Invention may be performed.
Figures 1 and
reprosent in section a pipe for smoking, the telescopic stem of
which is constructed according to my Invention. In Figure 1 the stem of the pipe
is represented in its expanded or lengthened state ready for use, and in Figure 2 in
its collapsed or shortened state.
Figure 3 represents in section, drawn to a larger scale, the socket mount and
parts connected therewith, and exhibits the manner in which the internal or supple-
mentary tube of the stem is connected with the said mount; and Figure 4
represents, drawn to a larger scale, the mount of the mouth-picce and exhibits the
manner in which the internal or supplementary tube of the stem is connected with
the said mount.
The same letters of reference indicate the same parts in the several Figures of
the Drawing.
a, b, c, are the metal tubes constituting the external or telescopic stem of the
pipe, the said tubes being of different diameters, the tubes b, c, sliding into and out
of one another, and the compound tube b, c, into and out of the largest tube a after
the manner of the tubes of a telescope, as will be understood by an examination of
Figures 1 and 2. Fixed within the tubular telescopic stem a, b, c, is a supple-
mentary tube of vulcanized india-rubber marked d, the said internal or supple-
mentary tube d constituting the true channel of the stem through which the smoke
passes and in which the oil of tobacco is deposited. One end of the internal or
supplementary tube d is secured to the ivory or other mount e fitted in the socket
of the pipe f, and the opposite end of the said tube d is secured to the ivory or other
mount g fitted to the mouth-piece h of the stem.
The largest tube a of the telescopic stem is screwed at a² to the mount e, and
the smallest tube c is screwed at to the mount g of the mouth-piece, as represented.
The mount g of the mouth-picce h is tubular (see Figure 4), that is, has a hole or
channel in its axis for the passage of the smoke and its outer end is screwed at gå for
receiving the mouth-piece h. The inner end of the mount g is provided with a
head g, to which head one end of the internal elastic tube d is secured by
expanding it over the said head and fixing it by coiling fine thread around the tube
at the base of the said head g³, as represented in Figure 4.
The mount e (see Figure 3) to which the other end of the elastic tube d is
secured has in its axis a swivelling tube i, having a head at its outer end and a
collar at its inner end, the said collar bearing against an internal shoulder in the
mount e. The end of the elastic tube d is secured to the swivelling tube i by
expanding it over the head i², and fixing it thereon by coiling fine thread around
the base of the said head, as represented in Figure 3. The hole in the mount e,
through which the swivelling tube i is passed, is closed by the tubular screw
stopper on which the conical cork or packing ring is placed for fitting the
bottom of the stem into the bowl of the pipe. By means of the swivelling tube i,
on which one end of the elastic or internal tube d is secured, the said tube d is
prevented from being twisted by the screwing into its place of the telescopic stem,
and hence the choking of the smoke passage of the stem is avoided.

page_text: The internal or smoke tube d is of a length somewhat greater than that of the
largest tube a, as represented in Figure 2, and the said tube d is situated con-
centrically with the tubes of which the stem is composed.
When the telescopic stem a, b, c, is expanded or lengthened for use, as represented
in Figure 1, the elastic smoke tube d is correspondingly lengthened and its diameter
reduced, said lengthened internal tube forming a continuous channel from the
wide end a of the stem to the mouth-piece at the narrow end c of the stem. When
the stem is shortened by the sliding of the tube c into the tube b and the two
tubes c, b, into the largest tube a, the internal or smokė box d returns to its normal
length, as seen in Figure 2.
In order to clean the internal or smoke tube dit is only necessary to unscrew the
tube a from the mount e and the smaller tube e from the mount g, to obtain access
to the ends of the said smoke tube sccured to the said mounts. By cutting the
thread at the heads i², g³, the smoke tube may be removed and cleaned and replaced
in the manner herein-before described. By then screwing the tubes a and c to the
mounts e and g the stem is again ready for use.
In applying my Invention to cigar holders I construct and arrange the parts of
the telescopic stem of the said cigar holders, in the manner herein-before described
and illustrated with respect to the telescopic stem of a pipe.
Having now described the nature of my Invention, and the manner in which the
same is to be performed, I wish it to be understood that I claim as my Invention,
the improvements in the telescopic stems of pipes for smoking and cigar holders,
herein before described and illustrated in the accompanying Drawing, that is to
say, the combination with the ordinary telescopic arrangement of the stem, of a
supplementary or internal tube of vulcanized india-rubber, the said supplementary
or internal tube constituting the true channel through which the smoke passes and
in which the oil of tobacco is deposited, the ends of the said supplementary or
internal smoke tube being secured to removeable mounts at the socket and mouth-
piece respectively of the pipe or cigar holder, substantially as described and illus-
trated.
In witness whereof, I, the said Edwin Lewis, have hereunto set my hand
and seal, this Twenty-sixth day of March, in the year of our Lord One
thousand eight hundred and seventy-seven.
