Year: 1859

page_text: LETTERS PATENT to John Gordon, Engineer, of 3, Railway Place, Fen-
church Street, in the City of London, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR PULPING COFFEE."
Sealed the 16th March 1860, and dated the 19th October 1859.
PROVISIONAL SPECIFICATION left by the said John Gordon at the
Office of the Commissioners of Patents, with his Petition, on the 19th
October 1859.
I, JOHN GORDON, Engineer, of 3, Railway Place, Fenchurch Street, in the
City of London, do hereby declare the nature of the said Invention for "Iм-
PROVEMENTS IN MACHINERY OR APPARATUS FOR PULPING COFFEE," (being improve-
ments on my Patent of date 23 January 1858), to be as follows:-
This Invention relates to a peculiar construction of the pulping cylinder or
barrel, and the mode of fixing the covering on the barrel with or without
nails, and for more accurately adjusting the barrel & breast.
The circumference of the of the barrel (if made of iron) is made with a loose
piece or stave, which is raised up by a wedge at each end; to complete the
cylinder, the barrel has a projecting ring round each end, between which the
covering is placed, making the entire barrel of the same diameter as the rings.
The covering is made of perforated copper or other material, and formed into
a tube having a hoop or projection placed inside to fit a recess in the circum-
ference of the barrel.

by the said John Gordon in the Great Seal Patent Office on the
17th April 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, JOHN
GORDON, of Three, Railway Place, Fenchurch Street, in the City of London,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of October, in the year of
our Lord One thousand eight hundred and fifty-nine, in the twenty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Gordon, Her special licence that I, the
said John Gordon, my executors, administrators, and assigns, or such others
as I, the said John Gordon, 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, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PULPING COFFEE," upon the
condition (amongst others) that I, the said John Gordon, executors or
administrators, by an instrument in writing under 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
calendar months next and immediately after the date of the said Letters
-Patent.
NOW KNOW YE, that I, the said John Gordon, do hereby declare the
'nature of said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The accompanying plans show the improvements in machinery for pulping
coffee, on a scale of one and a half inches to the foot.
Figures 17, 18, and 19, represents a cast-iron or metalic barrel in two
-pieces, with a raised ridge or ring round each end, which ring is to fit close to
the breast, being more accurately adjusted to the barrel by the rings fitting
close to the former at each end. Fig. 17 represents an end view of the barrel;
5 is the fitting up piece or stave; 6 is the barrel; 7 is the wedge under the
stave to keep it out to the true circle; 8 is a metalic screw, which passes
through the stave and wedge, and screws into a flange on the barrel end;

page_text: 9 is a recess in the barrel (or it may be placed in the stave), in which the
hoop lies, and on to which the ends of the copper sheet or other covering are
rivetted or otherwise fixed; the hoop in the recess also prevents the covering
from moving round, so that no tacks or other fastening are required. Figure 18
is an elevation (partly in section) of the barrel; Figure 19 is an end view of the
barrel with the wedge out, and showing the stave down and the barrel ready
to receive the metalic or covering tube which is placed between the end rings;
the stave is then raised to the true circle, and secured there by the wedge (7),
the screws (8) are replaced, and the barrel being now covered is ready for
work; (10) is the barrel shaft. The Invention of the raised metalic rings
I propose to apply as an improvement to the wood barrels at present in use.
The rings may either be put in over the metalic sheet, or the covering sheet
may be laid on between the rings.
I claim as my Invention, 1st, the sole right of using a metalic pulper
barrel with a moveable stave and projecting rings on the end, as described by
Figures 17, 18, and 19 on the Drawing.
2nd., I claim the sole right of using raised rings as an improvement on
the wood pulper barrels at present in use, as herein-before described.
In witness whereof, I, the said John Gordon, have hereunto set my
hand and seal, this Seventeenth day of April, in the year of our
Lord One thousand eight hundred and sixty.
Witness,
W. MACKENZIE,
33, New Broad St., London.
(L.S.) JOHN GORDON.
