Improvements in Roller Skates.
A communication to me from HERMANN KOERNER, of Essen, in the Empire of
Germany, Railway Clerk.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in roller skates, and the object of the
improvements is to provide means, by which any backward movement or slip of
roller skates may be prevented when passing up inclines, and also means by which
the velocity or speed may be regulated.
The prevention of backward movement of roller skates, for instance in ascending
an incline, is effected by means of a ball, roller, or excentric disc, arranged loosely
behind the skate wheel in a chamber or casing, formed at the sides by the supports
which carry the axle of the wheel, in front by the wheel itself, and at the back by
an inclined plate arranged between the said supports and firmly fixed thereto, the
lower end of such inclined plate being nearer to the circumference of the wheel
than its upper end.
If now there is any tendency of the roller skate to move backward, the ball,
roller, excentric disc, or the like is pressed and jammed by the reverse motion of
the wheel into the lower or narrower part of the space between the circumference
of the latter and the said inclined plate thereby instantly stopping the backward
movement of the wheel.
As soon as the roller skate moves forward again the ball, or the like, disengages
itself automatically. A stopping plate preferably made in one piece with the
inclined plate described prevents the ball or the like from being thrown out of its
chamber or casing by the rotation of the wheel.
For regulating the velocity or speed a spring is provided, attached to the heel of
the skate and having fixed to its outer end a block or plate of india rubber.
This elastic plate rubbing and pressing upon the ground when the fore part of
the foot is lifted, acts as a friction brake and allows the speed to be reduced
at will.
Suitable supports attached to the frame of the skate and embracing the leg above
the ankle will give the foot a proper support.

Improvements in Roller Skates.
A communication to me from HERMANN KOERNER, of Essen, in the Empire of
Germany, Railway Clerk.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this 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 drawing, that is to say :-
This invention relates to improvements in roller-skates, and consists in providing

page_text: the same with a brake, which comes automatically into action as soon as the skate
begins to roll backwards. This enables the skate to be used on roads inclining
upwards.
In the accompanying drawing a designates an india rubber ball, 6 the roller
covered with india rubber and c a wall inclining toward the roller b.
On the forward motion of the skate, the ball a is released and moves into a space
growing larger in front, and bounded by the wall o sides d and roller b. On
skating up an incline, the ball a falls back into the narrow part of the space between
the wall c and the roller b, and acts as a brake on the backward movement of said
roller.
Instead of a ball a, a roller or an excentric can be used, but this does not in any
way alter the nature of the invention.
The forward motion can be checked by lifting the point of the shoe, a spring e
with rubber plate fattached to the heel coming thus in contact with the ground.
To prevent the foot from turning over, supports, turning at h and ending in a
strap or band i surrounding the leg, are provided at both sides of the skate.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:―
.
1. A brake for roller skates, consisting in the combination of a ball a, inclined
wall c and roller b, substantially as and for the purpose herein described with
reference to the accompanying drawing.
2. A brake for roller skates consisting of a spring e with india-rubber plate f
attached to the heel of the skate, substantially as and for the purpose herein
described with reference to the accompanying drawing.
Dated this 21st day of October 1893.
