Year: 1873

page_text: LETTERS PATENT to David Fisken, of Stamfordham, in the County of
Northumberland, Gentleman, for the Invention of "IMPROVEMENTS
IN ROPE PORTERS FOR STEAM PLOUGHING MACHINERY."
Sealed the 5th August 1873, and dated the 11th February 1873.
PROVISIONAL SPECIFICATION left by the said David Fisken at the...
Office of the Commissioners of Patents, with his Petition, on the
11th February 1873..
I, DAVID FISKEN, of Stamfordham, in the County of Northumber-
land, Gentleman, do hereby declare the nature of my said Invention
for "IMPROVEMENTS IN ROPE PORTERS FOR STEAM PLOUGHING MACHINERY," to be
as follows:-
This Invention relates to improvements in rope porters to be used in
steam ploughing machinery.
That part of the porter which is fixed in the ground I form of two or
more prongs made of steel or other suitable material. These prongs are
made sharp so that they enter the ground by having pressure applied.

page_text: to them. The prongs can be made fast, either to a piece of timber or
other suitable material, or they may be extended upwards and be made
to form part of the cheeks or brackets which hold the pulley stud.
The pulley which holds and bears up the rope is mounted loosely upon
a stud or shaft held between two cheeks or brackets; these cheeks or
brackets are made fast to the other end of the piece of timber to which
the prongs are made fast, or as aforesaid they may be made fast to the
extension of the prongs that go into the ground. These checks or
brackets are extended or carried above the pulley, the one turned a little
to the right and the other a little to the left, and the ends of the checks
or brackets are bent over the pulley so as to prevent the rope from
being thrown out of position or from the groove of the pulley, but the
cheeks or brackets being turned a little to the right and left the bent-
over ends do not meet opposite to cach other, so that when the porter
is turned either to the right or to the left of the line of the rope the rope
can be taken out of the pulley and the porter removed. One of the
cheeks or brackets can be taken straight up above the pulley and the
other bent over the pulley or line of the rope so as to keep the rope in
position.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said David Fisken in the Great Seal Patent Office on
the 8th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
FISKEN, of Stamfordham, in the County of Northumberland, Gentleman,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of February, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs, and suc-
cessors, give and grant unto me, the said David Fisken, Her special
licence that I, the said David Fisken, my executors, administrators,
and assigns, or such others as I, the said David Fisken, my exe-
cutors, 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,.

page_text: exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN ROPE PORTERS FOR STEAM PLOUGHING MACHINERY," upon the
condition (amongst others) that I, the said David Fisken, my executors,
or administrators, by an instrument 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 calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said David Fisken, 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 in writing, and on reference being made to the
accompanying Drawings, that is to say :-
This Invention which relates to certain improvements in
rope porters
for steam ploughing machinery is illustrated on the accompanying
Drawings in Figures 1 and 2.
I form that part of the porter which is fixed in the ground of two or
more sharpened prongs 1 (made of steel or other suitable material),
which I secure to the lower end of a stake or piece of timber or other
suitable material 2, or extend upwards to form part of the cheeks or
brackets 3 which hold the pulley stud 4 upon which the rope pulley 5
is mounted loosely. In the former case the brackets are secured to the
upper end of the stake, but in either case they are extended or carried
above the pulley and turned aslant (Figure 1) with either one or both
of the upper ends bent inwards over the pulley (Figure 2) to prevent
the rope running from the groove thereof when they are in a line, but
so as to allow of its immediate removal on slightly turning the porter
either to the right or left of the line of the rope, or in the event of the
porter falling.
One of the brackets can be made with a joint or hinge at 6, and
turn upon the end of the stud 4, and be held in position by a nut 7,
and screw stud 8, the latter working in an open slot 9 in the fixed part
of the bracket. This bracket would be slotted at 6, so that when the
stud 8 was loosened it could be lifted up and turned down to allow of
the placing or removal of the rope.

page_text: Having now described the nature and object of my said Invention for
"Improvements in Rope Porters for Steam Ploughing Machinery,"
together with the manner in which the same is to be or may be
performed or carried into practical effect, I would remark in conclusion,
that I claim as my Invention, the peculiar construction and employ-
ment of the improved rope porter, substantially as and for the
purposes above described and as illustrated on the accompanying
Drawings.
In witness whereof. I. the said David Fisken. have hereunto set
