PROVISIONAL SPECIFICATION.
Improvements in Tobacco Pipes and the like.
I, JAMES ROBSON, of No. 34, Queenshead Road, Handsworth, in the County of
Stafford, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention of improvements in tobacco pipes, cigar tubes, and the like, consists
in forming the smoke channel so as to contain a valve which opens when the smoker
is drawing through the pipe, but closes the channel to the bowl of the pipe, when he
blows through the channel. There are also holes made from the channel through
the stem of the pipe into a tubular formed receptacle on the outside of the stem,
these holes or ports are closed on the outside by another valve which opens when
the person using the pipe blows into the pipe and through this valve into the outside
receptacle. The compressed air escapes from the receptacle out by way of a thin
slit and then strikes against the edges of a bell shaped tube encircling the pipe stem,
and emits a sound as a signal as by an ordinary whistle used by bicyclists and others.
The valves may be balls, indiarubber, sheet metal or other suitable material.
Instead of whistling a cylinder with piston and rod could be formed with or
attached to the pipe stem, so that by blowing the piston out its piston rod would
strike a bell fixed on the pipe, and thus give out a signal sound, or the piston rod or
clapper could in some cases be worked by the users hand.
Instead of a whistle a musical reed might be used for emitting the signal
sound.

Improvements in Tobacco Pipes and the like.
I, JAMES ROBSON, formerly of 34, Queenshead Road, Handsworth in the County
of Stafford, but now of 3, Devonshire Place, Selly Park, in the County of
Worcester, Mechanical Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention of improvements in tobacco pipes, cigar tubes, and the like, consists
in forming the smoke channel so as to contain a valve which opens when the smoker
is drawing through the pipe, and through a valve on the cover of the bowl of the
pipe, this valve closes when he blows through the channel of the pipe. There are
also holes made from the channel through the stem of the pipe into a tubular
formed receptacle on the outside of the stem, these holes or ports are closed on the
outside by another valve which opens when the person using the pipe blows into
the pipe and through this valve into the outside receptacle. The compressed air
escapes from the receptacle out by way of a thin slit and then strikes against the
edges of a bell shaped tube encircling the pipe stem, and emits a sound as a signal
as by an ordinary whistle used by bicyclists and others. The valves may be balls,
indiarubber, sheet metal, or other suitable material.
Instead of whistling a cylinder with piston and rod could be formed with or
attached to the pipe stem, so that by blowing the piston out its piston rod would
strike a bell fixed on the pipe, and thus give out a signal sound, or the piston rod or
clapper could in some cases be worked by the users hand, the piston may be returned
henring

page_text: Instead of a whistle a musical reed might be used for emitting the signal
sound.
For the purpose of more fully showing how my invention is carried into practice,
reference is to be had to the accompanying drawings, forming part of this Specifi-
cation, wherein the same numerals refer to similar parts in each of the figures.
Figure A, represents a pipe in section, having my improvements. 1, is the bowl
and stem which is attached to the mouth piece 2, by the rod 3, having the smoke
channel 4, the stem is connected to the mouth piece by an encircling tube 5, having
a sounding slit 6, the mouth piece smoke channel has an enlargement in which
works a valve 7, which in the act of inhaling slides along and closes the port way 8,
thus preventing air from entering through the slit 6, to the month piece channel 4.
The smoke can pass from the bowl round this valve by a side channel 9, or the
port 8, may be closed by a valve 10. Either of these valves opens the port 8; when
the person using the pipe, blows into the mouth piece, the air passing through the
port 8, and out of the slit 6, thus creating a whistling sound; the air at the same
time being prevented from passing out of the bowl by a lift valve 11, on the
perforated bowl cover 12. Figure B shows a cross section on the line a, a, in which
a musical tongue or reed 13, may be used in the slit 6. Figure C, with its cross
section Figure D, shows a modification, where the smoke is drawn through the
port way 8, the valve 14, closing the sound slit, thus preventing air entering.
This valve 14, opens when the mouth piece is blown into, and permits the air to
pass out of the slit 6, and creates the sound. During this action the valve 11, on
the bowl cover closes thus preventing the air from passing out by way of the bowl.
The valve 14, may be partly covered over by a cap 15, a hinged spring 16, being
used to turn over and hold the valve on the slit when desired. 17, is a trill bell.
By removing the pipe's bowl a cigar can be used.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1. The combination of a tobacco pipe or the like and a whistle or other sound
giving signal substantially as hercin described, or any modification thereof.
2. In a tobacco pipe arranging valves as herein described by which the user can
smoke when he is inhaling, and can create a whistling or other signal-sound, when
he blows into the pipe, or any modification thereof.
Dated this 27th day of January 1893.
