PROVISIONAL SPECIFICATION.
Improvements in Roller Skates.
I, JOHN EVANS, of 15 Edith Rond, Peckham in the County of Surrey,
Gentleman do hereby declare the nature of this invention to be as follows:-
This invention has for its object improvements in roller skates and consists in so
arranging and forming the rollers that the turning is greatly facilitated and also
that there is very much less friction in such skates.
For this purpose on the underside of the ordinary footboard of the skate I secure
a frame carrying in suitable bearings three rollers arranged centrally one in advance
of the other but the centre roller is slightly greater in diameter or set lower than
those in front and rear of it, by thus making the centre roller of increased diameter
or setting it lower it will be found that turning and moving in curved courses will
be rendered much less difficult than with skates of any ordinary construction.
In some cases other than three rollers might be used for example five but in all
cases the centre roller must be slightly of greater diameter or set lower than the
others in practice of an inch is found to be quite sufficient.
The skate may be secured to the foot by any of the ordinary methods.

COMPLETE SPECIFICATION.
Improvements in Roller Skates.
I, JOHN EVANS 15 Edith Road Peckham in the County of Surrey, 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 —
This invention has for its object improvements in roller skates and consists in so
arranging the rollers of such skates that when in use the turning is greatly
facilitated and also that there is very much less friction in such skates.
For this purpose on the underside of the ordinary footboard of the skate I secure
a frame or frames carrying in suitable bearings three rollers arranged centrally one
in advance of the other but the centre roller is of slightly greater diameter than
those in front and rear of it. By thus making the centre roller of greater diameter
or setting it lower it will be found that turning and moving in curved courses will
be rendered much less difficult than with roller skates of any ordinary construction.
In some cases other than three rollers might be used for example five but in all
cases the centre roller must be of greater diameter or set lower than the others in
practice of an inch will be found quite sufficient.
The skate may be secured to the foot by any ordinary methods.
DESCRIPTION OF THE DRAWING.
Fig. 1. is a side elevation and Fig. 2. an underside view of a skate having three
rollers arranged according to my invention.
To the underside of the footboard is attached the frame or frames & carrying

page_text: which forms the novel feature of my invention. The same object may be attained
by using a centre roller of greater diameter.
In some cases five or other odd number of rollers might be used in which case
the centre roller would be set down lowest or be of the greatest diameter and the
axes of the other rollers arranged in a curve from the centre towards the front and
rear of the skate.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. Arranging the rollers of a roller skate centrally in advance of each other
substantially as described.
2. Having the centre roller set lower or of greater diameter than the other
rollers substantially as described.
3. Arranging the axes of roller skates on a curved line substantially as described.
4. The improvements in roller skates substantially as described and shown by
the drawing.
