Year: 1873

page_text: LETTERS PATENT to Edward Cooke, of No. 44, Pershore Road,
Edgbaston, in the County of Warwick, for the Invention of "IM-
PROVEMENTS IN PIPES FOR SMOKING TOBACCO."
Sealed the 3rd March 1874, and dated the 9th October 1873.
PROVISIONAL' SPECIFICATION left by the said Edward Cooke at the
Office of the Commissioners of Patents, with his Petition, on the
9th October 1873.
I, EDWARD COOKE, of No. 44, Pershore Road, Edgbaston, in the
County of Warwick, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PIPES FOR SMOKING TOBACCO," to be as follows :→
The object of my Invention is to combine with pipes for smoking
tobacco convenient means of pressing the tobacco. within the bowl
during the process of smoking.
A pipe constructed according to my Invention has a small tube
supported upon it over the centre of the bowl, the said tube having fixed
at its lower end a plate with a hole in the centre, somewhat smaller

page_text: than the internal diameter of the tube. I support the said tube over
the bowl by attaching it to the centre of a cover or lid, which is made
to shut upon the rim by means of a hinge or in any other convenient
manner. The lower end of the said tube is situated about on a level
with the top of the bowl. Within the said tube is a rod, the upper part 5
of which nearly corresponds in diameter with the internal diameter of
the said tube and moves freely in it longitudinally. The lower part of
the rod is small enough to move freely through the hole in the aforesaid
plate, and the junction of the thicker part of the rod with the thinner
part forms a shoulder or collar. Upon the lower end of the said rod and 1
situated outside the tube is fixed a plate of any suitable contour, but of
such a diameter that it may be moved freely in a longitudinal direction
within the bowl. This last-named plate is herein-after called the
stopper.
Around the thinner part of the rod and situated within the before- 1
named tube, between the bottom thereof and the shoulder or collar of
the rod, is placed an extended coiled wire spring, one end of which bears
against the plate at the lower end of the tube, and the other against the
shoulder or collar of the rod, so that the stopper is retained close to the
outer side of the plate at the lower end of the tube, and the upper end 2
of the rod protrudes out of the said tube at the top.
In order to press the tobacco within the bowl during the process of
smoking a slight pressure is to be applied by the finger of the smoker
to the upper end of the rod when the spring will be compressed and the
stopper made to press upon the tobacco in the bowl: On removing the 2
finger the action of the spring will cause the stopper to resume its
former position near the level of the top of the bowl.
Instead of the spring being placed as herein-before described it may
be put between the upper end of the rod and the top of the tube, which
in that case is closed so as to confine the spring. When I use this 3
arrangement a longitudinal opening is made in the side of the tube
from a point near the lower end to within some little distance from the
upper end where it is extended for a. short distance in a transverse
direction.
A wire pin is secured to the upper part of the rod within the tube and 3
projects through the aforesaid opening. By means of this pin the said
rod may be raised by the hand so as to compress the spring and bring ·

page_text: the stopper against the lower end of the tube, where it may be retained
by turning the pin into the transverse part of the opening. When the
tobacco is ignited the pin is released from the transverse part of the
opening in the side of the tube, and the action of the spring causes the
stopper to press continually upon the tobacco until it is consumed.
Instead of a spring being placed above the upper end of the rod within
the tube the rod may be made sufficiently heavy to exert the necessary.
pressure upon the tobacco during the process of combustion.
The various parts of the nine as heroin before donosibed
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Cooke in the Great Seal Patent Office on
the 9th April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
COOKE, of No. 44, Pershore Road, Edgbaston, in the County of Warwick,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of October, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Cooke, Her special licence
that I, the said Edward Cooke, my executors, administrators, and
assigns, or such others as I, the said Edward Cooke, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, thic
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
PIPES FOR SMOKING TOBACCO," upon the condition (amongst others) that I,
the said Edward Cooke, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great. Seal Patent Office within six

page_text: calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Edward Cooke, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto
annexed, that is to say :-
When tobacco pipes are used for smoking tobacco it is often found to
be necessary or desirable for the purpose of facilitating the combustion
of the tobacco after it has been ignited to stop or press it down within
the bowl, and the operation of so stopping or pressing down the tobacco
has hitherto been performed by means of some detached instrument held
and applied by the hand, the said operation being generally inconvenient
to the smoker, more particularly when he is engaged in another pursuit
whilst smoking.
Now my Invention has for its object to combine with such pipes
convenient means of stopping or pressing down the tobacco within the
bowl during the process of smoking, for the purpose herein stated, and
consists in supporting upon the pipe over the centre of the mouth of
the bowl thereof a tube or frame, the said tube or frame being fitted
with a rod, which may be moved centrally up and down in the direction
of its length within the said tube or frame, the lower end of the said rod
being provided with a plate or stopper which is attached thereto, and
arranged so that it may be moved centrally up and down within the said
bowl and made to press upon the surface of the tobacco contained in the
same, the said plate or stopper being retained in a position near the level
of the mouth of the bowl when it is not required to press upon the
tobacco by means of a spring situated and acting so as to support the
aforesaid rod and stopper, or by means of a pin attached to the said rod
within the said tube or frame, which said pin projects through a longi-
tudinal opening in the side of the said tube, and may be made to engage
in a notch formed at or near one end thereof.
I will now proceed to particularly describe my Invention and the
manner in which the same is to be performed, reference being made to
the accompanying Drawing.
Each of the Figures of the accompanying Drawing is drawn respec-
tively to a scale somewhat larger than the ordinary size of the object in

page_text: order to more clearly illustrate my Invention, and at each of the said
Figures I employ similar letters of reference to denoto corresponding
parts, in so far as such parts appear or can be seen at each of such said
Figures respectively.
Figure 1 of the accompanying Drawing illustrates one method of
carrying out my Invention and shows a longitudinal view partly in
section of my improved pipe for smoking tobacco, that is to say, a
tobacco pipe with which is combined apparatus for stopping or pressing
down the tobacco within the bowl, constructed according to my In-
vention; Figuro 2 shows a side elevation of the same.
A is the bowl for containing the tobacco, and B, the stem, which said
parts A and B are well known and may be made as usual of briar,
meerschaum, or any other suitable material. It is however desirable for
the better carrying out of my Invention that the bore of the bowl A
should be parallel for a distance of about one half the depth of the said
bowl, measured from the mouth thereof. C is a tube situated perpen-
dicularly over the centro of the mouth of the bowl A, which said tube
may be formed of German silver or any other suitable material, the
internal diameter of the said.tube being by preference three-sixteenths
of an inch. At the bottom of the tube O is fixed a circular plate D
having a hole E in its centre, as shown in plan at Figure 3, which said
plate may be made of German silver or any other suitable material, and
may be secured to the tube C by soldering or other convenient means.
I prefer to support the tube C over the mouth of the bowl A by
attaching it to the lid F, the said tube being put through a hole made
in the centre of the said lid, and secured to the said lid by soldering or
other convenient means in such a manner that when the said lid is shut,
as shown in the Figure, the lower end of the said tube is situated within
the said lid on a level with or somewhat above the mouth of the
bowl A.
G, g, is a rod of silver, German silver, or other suitable material, the
upper part G of which for the whole or a part of its length nearly
corresponds in diameter with the internal diameter of the tube C, and
moves centrally up and down in the direction of its length within the
said tube. The lower part g of the said rod nearly corresponds in
diameter with the diameter of the hole E in the plate D, and moves
freely in the direction of its length through the said hole.

page_text: I prefer to make the rod G, g, in separate parts and to screw them
together, the upper end of the lower part being screwed with an
external thread, and the lower end of the upper part G being tapped
with a corresponding internal thread. The junction of the upper part G
of the rod with the lower part thus forms a shoulder or collar H: The i
lower end of the rod G, g, is fixed by soldering or otherwise to the
centre of the plate I, the said plate I being made of German silver or
other suitable material, and by preference of a form as illustrated
separately in plan at Figure 4. The said plate I nearly corresponds in
diameter with the diameter of the mouth of the bowl A, and may be 1
moved centrally up and down within the parallel part of the bore of the
said bowl. The said plate I is herein-after called the stopper.
J is a coiled wire spring, which I prefer to make of hard drawn brass
wire of No. 29 gauge. This said spring surrounds the lower part y of
the rod G, g, within the tube C, and is confined between the upper 1
surface of the plate D and the shoulder H of the rod G, g, the force of
the said spring being sufficient to support the said rod and the stopper I,
so that the latter is retained in a position near the level of the mouth of
the bowl A and the upper part G of the rod G, g, protudes for the most
part out of the tube C at the top. K is an ordinary hinge which 2
connects the lid F with the ferrule L, and 7 is an ordinary catch. I
prefer to form upon the upper or horizontal surface of the ferrule La
vertical rim 7 projecting upwards for a distance of about one-sixteenth of
an inch, and running parallel with the circumference of the said ferrule.
The lid F is made to fit over the said vertical rim / upon the ferrule L, 2
so that when the lid F is shut down upon the said ferrule it may occupy
a central position over the mouth of the bowl A, and thus ensure the
stopper I moving centrally within the said bowl.
The lid and the ferrule L may be made respectively of silver,
German silver, or other suitable material, and may be formed by the a
usual processes either of casting, stamping, spinning, or otherwise. The
said ferrule L is made to encircle the bowl A at the top, and is secured
thereto by pins or otherwise in the usual manner.
In order to stop or press down the tobacco within the bowl during the
process of smoking a slight pressure is to be applied by the finger of the 3
the unnow and of the w
A

page_text: shown in combination with other parts at Figures 7 and 8; Figure 10
shows an elevation of the same.
Figure 11 shows a longitudinal view, partly in section, of another
method of carrying out my Invention; and Figure 12 shows an elevation
of the same. The rod G, g, is made sufficiently heavy to exert the
necessary pressure upon the tobacco within the bowl during the process
of smoking. P is a collar which encircles the lower part 9 of the
rod G, g, the said collar being made moveable, so that the said collar
and the said rod may cach move up and down independently of the
other within the tube C. The pin M is secured by screwing or otherwise
to the moveable collar P, and projects through the opening N in the
side of the tube O, the notch n being made in this case at the bottom of
the opening N. To make use of this arrangement the collar P is drawn
down by the hand by means of the pin M. after the tobacco has been
ignited, the said pin being turned into the notch n, so that the spring J
is compressed and allows of the rod G, g, moving downwards within the
tube O and the stopper I pressing continually upon the tobacco in the
bowl during the process of smoking. When the tobacco is consumed
the pin M is disengaged by the hand from the notch n, and the reaction
of the spring J raises the rod G, g, and brings the stopper I into its
former position near the level of the mouth of the bowl A.
Figure 13 shows a detached vertical view, partly in section, of the
apparatus for stopping or pressing down the tobacco, as shown in com-
bination with other parts at Figures 11 and 12; Figure 14 shows an
elevation of the same.
Having now particularly described the nature of my Invention and
the manner in which the same is to be performed, I wish it to be under-
stood that I do not limit myself to the precise details herein described
and represented as the same may be varied without departing from the
nature of my Invention, and I declare that I make no claim to any of
the parts herein described or referred to respectively as the bowl, stem,
lid, ferrule, hinge, and catch, but I claim as my Invention the improve-
ments in pipes for smoking tobacco, herein-before described and
illustrated in the accompanying Drawing, that is to say, making such
pipes with the addition thereto of apparatus for stopping or pressing
down the tobacco within the bowl, constructed substantially as herein-

page_text: before described and represented separately in Figures 5, 6, 9, 10, 13,
and 14, and for the purpose set forth.
In witness whereof, I, the said Edward Cooke, have here-
unto set my hand and seal, this Thirty-first day of March, in
the year of our Lord One thousand eight hundred and seventy-
four.
