GEORGE CHAPMAN, of Queen's Buildings, Queen Victoria Street, in the City of
London. IMPROVEMENTS IN ROLLER SKATES." A communication from abroad by
Charles Henry Green, of the City, County, and State of New York, in the United
States of America.
The Invention has for its object improvements in roller skates, and relates to a
novel arrangement of parts whereby facility is afforded for executing various
evolutions thereon.
For this purpose the platform of the skate is supported by the rollers or wheels
at only a short distance from the ground, and such platform has three studs or
axles fixed thereto, two on one side and one on the other, upon which studs or axles
are mounted the wheels or rollers. These wheels or rollers are arranged so that
the two on the one side are situated one at or near the toe and the other at or near
the heel on the outside of the foot; whilst the other wheel or roller is placed on the
inside of the foot about the middle of the length thereof.
All the wheels or rollers are preferably of such a size that the platform of the
skate shall be below the axes thereof.
It is evident that the wheels or rollers may be arranged in a similar manner
underneath the platform, but such arrangement of the wheels or rollers is not so
beneficial as that above described.

GEORGE CHAPMAN, of Queen's Buildings, Queen Victoria Street, in the City of
London. "IMPROVEMENTS IN ROLLER SKATES." A communication from abroad by
Charles Henry Green, of the City, County, and State of New York, in the United
States of America.
The Invention has for its object improvements in roller skates, and relates to a
novel arrangement of parts whereby facility is afforded for executing various
evolutions thereon.
And in order that the Invention may be clearly understood and readily carried
into practice, I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side elevation, and Figure 2 a plan of a roller skate arranged
and constructed in accordance with this Invention.
a is the platform of the skate supported by the rollers or wheels b, bx, at only
a short distance from the ground, and such platform a has three studs or axles b¹, b¹,
fixed thereto, two.on one side and 'one b* on the other, upon which studs or axles b
are mounted the wheels or rollers b, bx. These wheels or rollers b, bx, are arranged
so that the two b, b, on the one side are situated one at or near the toe and the
other at or near the heel on the outside of the foot, whilst the other wheel or
roller b× is placed on the inside of the foot about the middle of the length thereof.
All the wheels or rollers b, bx, are advantageously of such a size that the platform
a of the skate shall be below the axes b¹, b¹, thereof.
Skates of this character are advantageously made of malleable cast iron or of
gun or other metal, but wood or other suitablo material may be employed.
It is evident that the wheels or rollers b, bx, may be arranged in a similar manner
underneath the platform, but such arrangement of the wheels or rollers. is not so
beneficial as that above described.
Having thus described the nature of the Invention, and the manner of performing
or carrying the same into practice, what I claim under the above in part recited
Letters Patent is the improved arrangement and construction of roller skates with
three wheels or rollers b, bx, the axes of which are placed above the platform or
foot plate a, substantially in the manner herein-before described and represented
in the Drawings hereunto annexed.
I also claim the improved arrangement and construction of roller skates having
three wheels or rollers, two on the outside and one on the inside below the foot plate
or platform a, substantially as herein-before described.
In witness whereof, I, the said George Chapman, have hereunto set my hand
and seal, this Twenty-eighth day of August, in the year of our Lord One
wound sight hundred and seventy-six
