IMPROVEMENTS IN ROLLER SKATES.
Year: 1875

page_text: LETTERS PATENT to Fred Isitt, of Bradford, in the County of York,
Gentleman, and David Farrer, also of Bradford, in the County
of York, Outfitter, for the Invention of "IMPROVEMENTS IN ROLLER
SKATES.'
Sealed the 12th May 1876, and dated the 16th November 1875.
PROVISIONAL SPECIFICATION left by the said Fred İsitt and David
Farrer at the Office of the Commissioners of Patents, with their
Petition, on the 16th November 1875.
We, FRED ISITT, of Bradford, in the County of York, Gentleman,
and DAVID FARRER, also of Bradford, in the County of York, Outfitter,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN ROLLER SKATES," to be as follows:-
This Invention relates to certain improvements in the rocking motion
of the four-roller skates.
The primary object of our Invention is to render the parts forming
the rocking motion more durable by breaking the contact between the

page_text: castings, and at thesame time to give the skater a greater range of
rocking motion without any sudden jerking, which latter detracts from
the pleasure of roller skating.
We effect these objects in the following manner :-Between the.
castings and that of the double bracket, which is secured to the sole of
the skate carrying the axle of the back rollers, we introduce a pad
of caoutchouc which is held in position by means of flanges cast upon
the axle bearer. The rocking motion starts from a fixed centre pin
passing through in a diagonal direction the outer flanges of the double
bracket, which is attached to the sole part of the skate and the axle
bearer, whereby a complete hinge is formed, the caoutchouc forming
a sort of spring or buffer capable of being compressed vertically, the
flanges of double bracket having slots to permit of this. The bias of
the skates to one side or the other is also responded to by the com-
pressibility of the caoutchouc on one side or the other radiating from the
fixed centre pin.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Fred Isitt and David Farrer in the Great Seal
Patent Office on the 16th May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FRED
ISITT, of Bradford, in the County of York, Gentleman, and DAVID
FARRER, also of Bradford, in the County of York, Outfitter, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-five, in
the thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Fred Isitt and David
Farrer, Her special licence that we, the said Fred Isitt and
David Farrer, our executors, administrators, and assigns, or such
others as we, the said Fred Isitt and David Farrer, our executors,

page_text: 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 ROLLER SKATES," upon the condition (amongst others) that we, the
said Fred Isitt and David Farrer, our executors or administrators, by
an instrument in writing under our, 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
:

page_text: of preventing the caoutchouc from slipping out from between the
brackets whilst the skates are in use.
In witness whereof, I, the said Fred Isitt, have hereunto set my
hand and seal, this Fifteenth day of May, in the year of our
Lord One thousand eight hundred and seventy-six.
Witness,
JOHN WAUGH,
