IMPROVEMENTS IN ROLLER SKATES
Year: 1876

page_text: LETTERS PATENT to William Henry Pinder, of Leeds, in the County of York,
for the Invention of "IMPROVEMENTS IN ROLLER SKATES."
PROVISIONAL SPECIFICATION left by the said William Henry Pinder at the
Office of the Commissioners of Patents on the 26th April 1876.
WILLIAM HENRY PINDER, of Leeds, in the County of York.
ROLLER SKATES."
"IMPROVEMENTS IN
I use a single plate of metal or other suitable substance hinged on the top of the
foot stock. The heel of the user rests on the foot stock independent of the plate.
The roller carriages are mounted on vertical pins on which they may radiate
horizontally. Each back and front carriage is provided with a bracket or radial
arm having in it a slot. In order to give the required radial motion to the bracket
or carriage containing the rollers two pins are attached to the metallic or other
suitable plate, which pass through the foot stock vertically into the slots in the
radial arm. By'a side or lateral pressure of the foot of the skater upon the fore
part of the plate motion is conveyed through the pins to the radial arms, and thence
the required radial motion is imparted through the roller carriages to the four
rollers simultaneously, whereby the skates are so directed that the skater may
turn in any direction. At the heel of the foot stock I provide a woollen or other
clastic cushion for the purpose of allowing the heel to move with the other part of
the foot as required. The rollers are brought back to their direct or parallel position
by means of a spring fixed upon the foot stock and under the metallic or other
suitable plate.

transverse section through A, B, Fig. 1.
a is a plate of metal or other suitable material which is hinged at b on the top
of the foot stock c. The heel of the user rests on the pad 7 on the foot stock c
independently of the plate a; d are the rollers which are provided with the
carriages e, and are mounted on the vertical pin's f, these being secured to the
foot stock c by means of suitable screws g or their equivalents. The rollers d are
fitted so as to revolve freely on the pins in the carriage c. Each back and front
carriage e is provided with a radial arm & having in it a slot J. In order to give
the required radial motion to the bracket or carriage e carrying the rollers d, two
pins Kare attached to the metallic or other suitable plate a and passed through
the foot stock vertically into the slots J in the radial arms i. By a side or lateral
pressure of the foot of the skater upon the fore part a¹ of the plate a, a radial
motion is conveyed through the pins K to the radial arms i, and thence this
required radial motion is imparted through the roller carriages e to the four
rollers & simultaneously, whereby the skates may be so directed that the skater
can turn in any direction. At the heel of the foot stock c I provide a woollen or
other elastic substance or cushion for the purpose of allowing the heel to move
with the other part of the foot as required. The front fastening straps m are
attached to the front part of the plate a. The rollers d are brought back into their
direct or parallel position by means of a spring n fixed by means of the screw o
upon the foot stock c and under the metallic or other suitable plate a.
The straps
are of ordinary construction.
Having now described the nature of my said Invention, and having shewn by
Drawings how the same may be carried into practice, I would have it understood
that I do not limit myself to the exact limits, details, or configuration of the
various parts I have explained and shewn, as the same may, of course, be varied

page_text: or modified without in any way departing from my Invention; but what I do
claim and desire to be secured to me by Letters Patent is-
First. The arrangement, construction, and application in roller skates of plate a,
pins K, and carriages e, with the radial arms i and parts connected therewith, for
imparting to the said skate the required direction, whereby the operator can move
the rollers simultaneously to any required angle, substantially as herein set forth.
Second. The application of woollen or elastic cushion at the heel of the skate,
substantially as and for purposes herein set forth.
Third. The arrangement and combination of the various parts forming the skate,
substantially as herein set forth.
In witness whereof, I, the said William Henry Pinder, have hereunto set my
hand and seal, this Twenty-first day of October, in the year of our Lord
One thousand eight hundred and seventy-six.
