Year: 1876

in the County of Kent, for the Invention of "IMPROVEMENTS IN
CAT"
ROLLER
Sealed the 21st October 1876, and dated the 15th May 1876.
PROVISIONAL SPECIFICATION left by the said John Pound and Charles
Richard Stevens at the Office of the Commissioners of Patents on the 15th May
1876.
JOHN POUND and CHARLES RICHARD STEVENS, both of Lee, in the County of
Kent. "IMPROVEMENTS IN ROLLER SKATES."
The improvements consist in giving simultaneous radiation to the fore and aft
axles of roller skates by the foot, through means of a steering rod (and not by the
canting of the sole plate) actuated by a lever or pin fixed thereon, and inserted in
or placed by the heel of the boot, and also by a curved or other shaped plate fixed
to said steering bar and forming part of the heel or toe attachment or strap, or
otherwise, or by either or any of the above means used separately or collectively.
Further, in forming the heel or toe strap of two pieces, with two fasteners or sets
thereof, one on either side, and a loose attachable instep or toe strap sometimes
combined with two or more auxiliarly straps passing under the sole plate and over
the instep or toes or both, for the purposes of fixing the foot more securely when the
heel pin above-mentioned is not used, all or any of said straps and the fastenings
thereof being rendered capable of adjustment on either and both sides of the foot,
whereby the heel or foot may be centred more truly on the sole plate. The
improvements can be performed by making the fore and aft carriages holding tho
rollers bogied, and the steering rod of metal furnished with two pins projecting
The said
downwards and fitting into a fork or guide fixed to each bogey carriage.
rod is also supplied with a pin or heel spike projecting upwards and passing thro'
a slotted hole in the sole plate, also with heel or toe attachment plates. The skate
being fitted on the foot by the improved fastenings or otherwise, the canting of the
foot causes the heel pin or heel or toe attachınent plates which are canted with it to
move the steering rod, which by means of its lower pins move the guides of the
bogies, and so the axles are made to radiate in proportion to the cant of the
foot

JOHN POUND and CHARLES RICHARD STEVENS, both of Lee, in the County of
Kent. "IMPROVEMENTS IN ROLLER SKATES."
The improvements consist in giving simultaneous radiation to the fore and aft
axles of roller skates by the leg, through means of a steering rod (and not by the
canting of the sole plate) netuated by a lever, which may be a pin, bar, or plato or
of other convenient for fixed thereon and inserted in or placed by the heel of the
boot, and also by one or more curved or other shaped plates, straps, or rods fixed
to said steering rod and forming part of the leg heel or toe attachment, or by either
or any of the above means used separately or collectively. Further, in forming the
leg heel or toe strap of two pieces with two fasteners or sets thereof, one on either
side, and a loose attachable instep or toe strap sometimes combined with two or
more auxiliary straps passing under the sole plate and over the instep or toes or
both, for the purposes of fixing the foot more securely to the soleplate. All or any
of said straps and the fastenings thereof being rendered capable of adjustment on
either and both sides of the foot or leg whereby the heel or foot may be centred
more truly on the sole plate. The improvements can be performed by making the
fore and aft carriages holding the rollers bogied or otherwise, and the steering rod
of metal furnished with two pins projecting downwards and fitting into a fork or
guide fixed to each bogey carriage; the said rod may also be supplied with a pin
or heel spike projecting upwards and passing through a slotted hole in the sole plate,
also with leg heel or toe attachment plates or contrivances. The skate being
fitted on the foot by the improved fastening or otherwise, the action of skating
causes the leg heel or toe attachment to move the steering rod which by means
of its lower pins moves the guides of the bogies or other mechanical equivalent and
so the axles are made to radinte in proportion to the cant of the body. A con-
venient mode of executing the Invention is shown in the accompanying Sheet of
Drawings, in which Figure 1 gives a part side elevation and part longitudinal section
of a skate, Figure 2 represents the same in plan, and Figure 3 is a cross section on the
line A, B, looking towards the heel of the skate. Like letters represent like parts
in all the Figures. a is a metal strip or cover to the channel which is cut in the foot-
board for the reception of the revolving rod b; c, c, are branches of b, and are securely
fixed thereto at right angles; t is a bar or tiller likewise securely fixed to the bar b,
it may be attached to the foot of the user of the skate by any convenient straps 8
or other attachment. When t is caused to describe an arc (by the inclination of
the leg of the wearer) the branches c perform corresponding arcs and cause the
arms e to impart a horizontal and partial revolution to the vertical carrier d, and
also to its contained horizontal axles ; is a wide steel spring securely fixed at
right angles to the skate axis, and its eflect is to constantly restore the axle h to
its normal position when the radiating effort is suspended ; is merely a convenient
support for d so arranged as to allow of its free revolution; m is a thumb-screw by
which the effect of the spring may be increased or diminished; is a hinge fitted
to the tiller t to allow of backward and forward movement. It should be parti-
cularly noted in Figure 3, which shows the tiller and wheels at a considerable angle, 4
that the footboard has not departed from the horizontal, but is perfectly parallel
to the axle h, which is likewise in no measure inclined; and, moreover, that the
vertical shaft also maintains its verticallity. The radiation of the wheels is
entirely performed by the tiller t which is the essence of this Invention, and not
by either the inclination of the foot board or by inclined axles, which are the
essential features of the Plymton skate. We would remark that the Invention
may also be performed (though not so shown in the Drawing) by placing the rod b
below the foot plate, arranging the steering bar c and the tiller e to accommodate

attachment 8 shown, we sometimes use metal clamps fixed and hinged on the tiller
bart, for the purposes of more securely holding the skate to the leg.
In witness whereof, wo, the said John Pound and Charles Richard Stevens,
have hereunto set our hands and seals, this Thirteenth day of November, in
the year of our Lord One thousand eight hundred and seventy-six
