PROVISIONAL SPECIFICATION.
Improvements in or relating to Tobacco Pipe and like Cleaners.
We JOSEPH LUCAS of Llandough in the County of Glamorgan Officer in Her
Majesty's Customs and AUGUSTUS HOBBS of 63 Victoria Avenue in the County
Borough of Newport Solicitors Managing Clerk do hereby declare the nature of
this invention to be as follows:-
The invention consists of a cylinder A shown in Figure 1 of the sheet herewith
carried and formed on a spiral spring B shown in the same figure capable of being
extended in a straight line the cylinder containing a piston or ejector and rod C
shown on Figure 1 working through the cylinder A and carried or supported by
the part of the spiral spring at the rear of the cylinder.
The cylinder A consists of a hollow steel tube slit longitudinally on one side
through its length with a series of slits a a also shown in Figure 3 running
diagonally from such longitudinal slit and from each side of it to the extent of one-
fourth of the circumference of the cylinder.
From the free end of the cylinder a slit shown at b b on Figure 4 opposite to and
parrallel with the longitudinal slit aforesaid extends to two thirds the length of the
cylinder and which slit at the free end or top of the cylinder is widened out so as
to form lips as shown at b b.
The ring c which is shown round cylinder on Figure 1 is intended to pass to and
fro along the same so that when placed opposite the free end of the cylinder the
lips will slightly expand and when brought to the free end the lips will be
contracted to the original diameter of the cylinder.
The spring and cylinder are contained in the circular case D in Figure 1. The
spring is carried on the pin E passing through centre of circular case D as shown
in Figure 1. The spring is extended or withdrawn by turning the thumbscrew
shown at F on Figure 2 which is mounted on pin E.
A diaphragm of india rubber is placed in case D as shown in section at G on
Figure 1.
On the free end of the cylinder being inserted in the tube of a tobacco pipe the
ring c is with drawn to the opposite end the lips at bb thereupon expanding to the
full diameter of the tobacco pipe tube. The cylinder is then passed up the whole
length of the tobacco pipe collecting all the accumulations found therein. On
withdrawing the cylinder the ring is carried to the free end thereof restoring it to
its original diameter. The piston or ejector C is then brought forward to eject the
accumulations from the pipe tube out of the cylinder.
On withdrawing spring into case the india rubber diaphragm at G through
which the cylinder and spring work will collect any accretions taken up by the
spring and outside of cylinder from the tube of the tobacco pipe.
A pin is shown at d on Figure 1 to prevent the cylinder from being withdrawn
too far into case D.
A catch is shown on rod C at e in Figure 1 to work ejector to and fro.
A circular indentation on outside of cylinder A is shown at f on Figure 5 to
prevent, ring from slipping off cylinder.
Figure 1 is a section of case D showing cylinder Aª and -spiral spring. B and
diaphragm of india rubber G and pin d.

Improvements in or relating to Tobacco Pipe and like Cleaners.
We JOSEPH LUCAS of Ty-fyr-lan Llandough in the County of Glamorgan
Officer in Her Majesty's Customs and AUGUSTUS HOBBS late of 63 Victoria
Avenue in the County Borough of Newport and now of Gibbs Road Cross Hauds
in the County Borough of Newport Solicitors Managing Clerk 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 :-
.
The invention consists of a cylinder A Figure 1 shown on drawing left with the
Provisional Specification carried and formed on a spiral spring B shown in said
drawing capable of being extended in a straight line the cylinder containing a
piston or ejector and rod C working through the cylinder A and carried or
supported by the part of the spiral spring at the rear of the cylinder.
The cylinder A consists of a hollow steel tube slit longitudinally on one side
through its length with a series of slits a a running diagonally from such
longitudinal slit and from each side of it to the extent of one fourth of the
circumference of the cylinder.
From the free end of the cylinder a slit opposite to and parralel with the
longitudinal slit aforesaid extends to one third the length of the cylinder and
which slit at the free end or top of the cylinder is widened out so as to form lips as
shown at bb Figure 4. The ring c which is shown round cylinder is intended to
pass to and fro along the same so that when placed opposite the free end of the
cylinder the lips bb will slightly expand and when brought to the free end of the
cylinder the lips will be contracted to the original diameter of the cylinder.
The spring and cylinder are contained in the circular case D. The spring
is carried on the pin E in centre of circular case. The spring is extended or
withdrawn by turning the thumbscrew shown at F. A diaphragm of india rubber
is placed in case D the section of which is shown at G.
On the free end of the cylinder being inserted in the tube of a tobacco pipe the
ring c is withdrawn to the opposite end, the lips bb thereupon expanding to the
full diameter of the tobacco pipe tube. The cylinder is then passed up the whole
length of the tobacco pipe collecting all the accumulations found in the tube.
On withdrawing the cylinder the ring is carried to the free end of cylinder
restoring it to its original diameter the piston or ejector C is then brought forward
to eject the accumulations from the pipe tube out of the cylinder. On withdrawing
spring into case the india rubber diaphragm at G through which the cylinder and

page_text: spring work will collect any accretions taken up by the spring and outside of
cylinder from the tube of the tobacco pipe, a pin is shown at d to prevent the
cylinder from being returned too far into case D.
A catch is shown on rod Cat e to work ejector to and fro. A circular indentation.
on outside of cylinder is shown at f to prevent ring from slipping off cylinder.
Figure 1 on drawing is a section of case D showing cylinder and spiral spring and
diaphragm of india rubber and pin d.
Figure 2 on drawing is a vertical cross section of Figure 1 at H H showing the
cylinder and spiral spring in section which shows the longitudinal slit g in cylinder
and elit continued through the whole length of the spiral spring at h h.
Figure 3 on drawing shows the cylinder withdrawn from case with longitudinal
slit g and the diagonal slits a a running from each side thereof to one fourth of
circumference of cylinder.
Figure 4 on drawing is an illustration of the slit b b which extends to one third
of the whole length of the cylinder showing the curved lips at b b.
Figure 5 on drawing is an illustration of the outside of case D showing the
cylinder withdrawn and showing ejector and rod C and catch e.
The diaphragm of india rubber is held in position by indentation in case D shown-
at k.
Having now particularly described and ascertained the nature of our said inven--
tion and in what manner the same is to be performed we declare that what we
claim is
In combination with a spiral spring a perforated cylinder capable of being
compressed to varying diameters and of adjusting itself to various curves working-
through an india rubber diaphragm substantially as and for the purpose herein.
set forth.
