AN IMPROVED PULPING AND COMPRESSING MACHINE FOR THE TREATMENT OF PEAT AS A FUEL AND GAS FOR ILLUMINATING PURPOSES
Year: 1865

page_text: LETTERS PATENT to Charles Worssam, Engineer, of Commercial Wharf,
Kingsland Road, and George Evans, Gentleman, of Gloucester Place,.
Portman Square, both in the County of Middlesex, for the Invention of
"AN IMPROVED PULPING AND COMPRESSING MACHINE FOR THE TREATMENT OF
PEAT AS A FUEL AND GAS FOR ILLUMINATING PURPOSES."
PROVISIONAL SPECIFICATION left by the said Charles Worssam and
George Evans at the Office of the Commissioners of Patents, with
their Petition, on the 26th December 1865.
CHARLES WORSSAM, Engineer, of Commercial Wharf, Kingsland Road,
and GEORGE EVANS, Gentleman, of Gloucester Place, Portman Square, both
in the County of Middlesex, do hereby declare the nature of the said Inven-
tion for "AN IMPROVED PULPING AND COMPRESSING MACHINE FOR THE TREATMENT
OF PEAT AS A FUEL AND GAS FOR ILLUMINATING PURPOSES," to be as follows:-
Firstly, the machine consists of a rotatory horizontal circular table of iron.
of great strength, having a number of holes in the table in the form of a
brick. Each hole is lined with finely perforated metallic plates; each hole has
a piston or plunger with a perforated top and a wheel at the bottom. This
plunger or piston runs on a circular inclined tramway in the form of a
horizontal screw of one thread, so as the table revolves the plungers or pistons
rise and fall, and are pulled down by means of a cam at the bottom. Each
hole or box is provided with a perforated cover, which slides off and on with

page_text: a wheel attached to the upper surface, which works in a fixed cam as the
table rotates. The horizontal circular table is firmly held in its position by
powerful side brackets, each provided with rollers placed in opposition to all
counter movements, the under rollers supporting the table by a rim, which is
again pressed on from above by the upper rollers, which keep the table in
steady working gear while it rotates.'
Secondly, we now describe the pulping and feeding apparatus, which is fixed
over the holes or boxes. It consists of an iron cylinder with three or more
horizontal plates with holes in them of different dimensions, a vertical shaft
with knives attached; as the knives move round the peat fibres are broken
up, and the whole material is broken up through the plates, and forced into
the boxes of the horizontal table; the covers close by means of the cam;
the table is moved by steam power with suitable gear; the plungers rise up
the circular inclined plane or screw, and gradualy compess the peat; the
water is forced through the perforations, the pressure being complete the
boxes pass under the cam and open; the plunger or pistons rise over a
sudden incline, and force out the block; the plunger then lowers in the
box, and passes under the feeder, it is then filled, the covers close, the rotation
of the table continues.
Having thus described the nature of our Invention, and the manner of
performing the same, we would have understood that we claim the whole
and every part of this machine as a combined apparatus for pulping and
compressing peat; we claim particularly the perforated plates, the cam, and
inclined screw.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Worssam and George Evans in the Great Seal Patent
Office on the 26th December 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
WORBSAM, Engineer, of Commercial Wharf, Kingsland Road, and GEORGE
EVANS, Gentleman, of Gloucester Place, Portman Square, both in the County
of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of June, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant a
into us, the said Charles Worssam and George 'Evans, Her special licence

page_text: that we, the said Charles Worssam and George Evans, our executors,
administrators, and assigns, or such others as we, the said Charles Worssam
and George Evans, our 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 "An In-
PROVED PULPING AND COMPRESSING MACHINE FOR THE TREATMENT OF PEAT AS A
FUEL AND GAS FOR ILLUMINATING PURPOSES," upon the condition (amongst
others) that we, the said Charles Worssam and George Evans, our executors
or administrators, by an instrument in writing under our, or one of our, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 we, the said Charles Worssam and George Evans,
do hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Drawings, that is to say
a
ול
wheel
Firstly, the machine consists of a rotatory horizontal circular table of iron
of great strength, having a number of boxes in the table in the form of a brick.
Each box is lined with metal plates finely perforated, each box having a piston
or plunger with a perforated top and wheel at the bottom. This plunger or
piston runs on a circular inclined tramway in the form of a horizontal screw
of one thread, so as the table revolves the plungers or pistons rise and fall in
the boxes, and are pulled down by means of a cam at the bottom. Each box
is provided with a perforated cover, which slides off and on with
attached to its upper surface, which works in a fixed cam as the table;
table rotates.
The horizontal circular table is firmly held in its position by powerful side
brackets, each provided with rollers placed in opposition to all counter move-
ments, the under rollers supporting the table by a rim, which is again pressed
on from above by the upper rollers; there are also side rollers to the brackets
to keep the table in steady working gear while it rotates.
Secondly, we now describe, the pulping and feeding,
apparatus, which
15 fixed
over the boxes. It consists of an iron cylinder with a vertical shaft with knives
attached, placed at angles, so that as the knives move round the fibres of the
peat are forced through the different plates and then broken up, and the whole
body of the material is well reduced to a pulp, it is then propelled downwards

purpose of extracting the water when under pressure; J, the horizontal table
at Figure 2; L, the top view of cog wheel B at Figure 2.
Having now particularly described and ascertained the nature of our said
Invention, and the manner in which the same is to be performed, we claim
particularly the drying or evaporating the water from peat by means of heating
surfaces of plates or cylinders by steam, further we claim the perforated
plungers, and boxes, and covers, and the arrangement or combination of parts
for so working them as in this Specification and appended Drawings is described
and shewn.
In witness whereof, we, the said Charles Worssam and George Evans,
have hereunto set our hands and seals, this Twenty-sixth day of
December, in the year of our Lord One thousand eight hundred and
sixty-five.
