Year: 1858

page_text: LETTERS PATENT to John Gordon, of 3, Railway Place, Fenchurch Street,
in the City of London, Engineer, for the Invention of "IMPROVEMENTS
IN. MACHINERY OR APPARATUS FOR PULPING COFFEE."
Sealed the 30th July 1858, in pursuance of an Order of the Lord Chancellor,
PROVISIONAL SPECIFICATION left by the said John Gordon at the
Office of the Commissioners of Patents, with his Petition, on the
23rd January 1858. -
I, JOHN GORDON, of 3, Railway Place, Fenchurch Street, in the City of
London, Engineer, do hereby declare the nature of the said Invention for.
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PULPING COFFEE," to be as
follows:-
This Invention relates to a peculiar construction and arrangement of the
pulping cylinder or barrel and the breast of coffee-pulping machines, and con-
sists in making the barrel with a number of spiral or inclined grooves or flutes
upon its surface. The breast consists of a plate, curved to fit the periphery
or surface of the barrel, and having a number of inclined recesses or grooves
made with slightly projecting edges, and formed upon the concave surface of
the plate, each recess or groove being terminated at its lower. end by an
opening or passage to allow of the escape of the "parchment" or pulped

page_text: coffee, the skins and pulp being drawn over the projecting edges of the inclined
recesses or grooves in the breast, by the action of the spirals on the barrel.
The breast may be adjusted near to or further from the barrel by suitable
adjusting screws or wedges.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent,
and of an Order of the Lord Chancellor, by the said John Gordon in the
Great Seal Patent Office on the 31st July 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GORDON, of 3, Railway Place, Fenchurch Street, City of London, Middlesex,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of January, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Gordon, Her special license that I, the said John
Gordon, my executors, administrators, and assigns, or such others as I, the
said John Gordon, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR PULPING COFFEE," upon the condition
(amongst others) that I, the said John Gordon, by an instrument in writing
under my hand and seal, 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 my 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 (that is to say):-
The accompanying plans show the machinery for pulping coffee on a scale of
one and a half inches to a foot.
Fig. 1 is a plan of the machine; Fig. 2 is a front elevation of the machine;
Fig. 3 is a cross section and elevation of the machine through A, B, and C, D;

page_text: Fig. 4 is a side elevation; Fig. 5 is a plan of barrel or cylinder; Fig. 6 is a
plan of the breast; Fig. 7 is a cross section of the breast through G, H; Fig. 8
is an elevation of the concave side of breast, shewing the inclined grooves or
recesses; Fig. 9 is a longitudinal section of breast through E, F. The corre-
sponding letters on the above respective nine Figures indicate the same
parts.
a is the framing of the machine; b, the breast, made of iron or other
suitable material; c, the inclined grooves or recesses on the concave side of the
breast;
are points of the breast which extend over the barrel, so as to guide
the cherry coffee into the grooves or recesses; e, e, openings or passages at the
bottoms of grooves or recesses, to allow of the escape of the parchment or
pulped coffee; f is the projecting edge on the lower side of the recess or
groove, over which the pulp or skin of the cherry coffee is drawn by the action
of the uneven surface of the barrel after having been squeezed out; g, the
brackets or ends of the breast which pass through the side framing, and are acted
on by the set screws h, h, against wooden wedges i, i, so as to keep the breast
steady when at work, and in its proper place; j is the barrel or cylinder in a
horizontal position, made with a number of spiral flutes or grooves of the same
angle as the angle of the projecting edges of f on the concave side of the
breast. This barrel may be made of copper, brass, or iron, exclusively, or of
wood or iron covered with brass or any other suitable material or materials.
The flutes may be cut from the solid barrel, or may be formed of a covering of
thin corrugated brass or copper, or other suitable material; or it may be
punched from the inside or raised and jagged from the outside, so as to give
the barrel an uneven surface, to draw the skins over the raised side of the
grooves or recesses; k is the back board that conducts the pulp away after it
falls from the breast; 1 is the hopper to hold the cherry coffee, and is fixed to
the side frames; m is the pulley to drive the machine, or it may be driven in
the usual way by toothed wheels. Fig. 10 is a section through I, K, and
shewing the barrel in a vertical position; Fig. 11 shows an elevation of the
barrel or grooved cone; Fig. 12 is the plan of the fixed conical circular breast.
The corresponding letters on the above respective three Figures 10, 11, & 12,
indicate the same parts. n is the inclined groove or recess on the in or concave
side of the round or circular breast; o is the opening at the centre, through
which the parchment or pulped coffee escapes; p is the raised side of the
recess or groove over which the rough or uneven surface of the barrel draws
the pulp or skin of the coffee; q, the opening in the breast through which the
pulp falls, and is carried away; », a circular hopper formed by the breast and
the barrel; s, s, two brackets to support and fix the breast on the framing or

page_text: flooring; t, vertical shaft of barrel, and to work in a footstep in the usual way,
such as a corn or flour mill, and. raised or lowered at pleasure; the barrel may
be driven in the same way by bevel or face toothed wheels; u is the barrel,
made of the same material or materials, and the surface uneven, as described
on Fig. 5 of the Drawing.
.
Figs. 13, 14, and 15 are almost the same as the last three Figures 10, 11,
& 12, but the machine inverted, and fed from the centre. Fig. 13 is a plan
of round, conical, or circular breast, with the inclined grooves or recesses on
the convex side; Fig. 14 is a section and elevation through. L, M, and N, O;
Fig. 15 is a plan of the machine. The corresponding letters on the above
respective three Figures 13, 14, and 15 indicate the same parts.
vis the
hopper for the cherry coffee; the machine being fed from the centre, is
attached to the barrel, and fixed to the vertical shaft 2; w is the web of the
barrel, made of any suitable material or materials, and the surface uneven, as
described on Fig. 5 of the Drawing, but the uneven surface is on the concave
side. x, the inclined grooves or recesses on the convex side of the conical
breast 3, the parchment or pulped coffee escaping at y. 1 is the raised side of
the groove or recess over which the uneven surface draws the pulp or skin of
the coffee, which then falls down through the openings of the fixed breast;
2, vertical shaft of barrel, and to work in a footstep, such as a common corn or
flour mill, and to be raised or lowered at pleasure in the same way, and driven
by face or bevel wheels in the usual way. 3, the conical breast.
I claim as my Invention, the sole right of using a barrel or cylinder, made
uneven on the surface by spiral grooves (as shewn by Figs. 5 & 11 on the
Drawing), or chequered, and working against a breast with inclined recesses
or grooves (as shewn by Figs. 8 & 12 on the Drawing), but I do not
confine myself exactly to these forms, as they may be made according to
Figs. 13 & 14, shown on the Drawing.
In witness whereof, I, the said John Gordon, have hereunto set my
hand and seal, this Thirty-first day of July, in the year of our Lord
One thousand eight hundred and fifty-eight.
