Cycle Sledges.
WILLIAM JOSIAH BARRETT 17 Bury Road Thetford Norfolk Inland Revenue
Officer do hereby declare the nature of this invention to be as follows:--
Attachments to certain classes of cycles for running them on snow and ice>
consisting of skates or runners to attach to forks or frames of cycles and a false
rim, or rims, spiked or roughened to prevent slipping. These false rims are to be
a little larger than the rims of cycles used, and are fastened to the true rims with
canvas or other material, laced round the true rim or otherwise fastened: they are
to be constructed of some elastic material so that the part in contact with the
ground shall give to the inequalities of it and are to take the place of the tyres
which are dispensed with. The following is the method of attaching to the rear
driving bicycle, the front wheel is taken out and a skate or runner is attached to
the front forks by means of false forks of proper length, another skate or runner is
attached to the back forks to run behind the hind wheel, the tyre of which is
removed where detachable & replaced by false rim; the hind skate to be of
sufficient distance from forks to allow the false rim to press on ground, and leave a
space between it and the true rim. To attach to rear driving tricycle a skate is
substituted for front wheel and both hind wheels are provided with the false rims,
and skates are fixed to frame of cycle to run beside each hind wheel.
Where tyres
are fixed, wheels fitted with false rims can be substituted for cycle wheels where
required, or if pneumatic tyres they can be deflated to fix false rims.

I, WILLIAM JOSIAH BARRETT 17 Bury Road Thetford Norfolk Inland
Revenue Officer 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 :-
The invention consists of attachments to certain classes of cycles (for running
them on ice and snow) namely the rear driven and front steered class of bicycles,
and that class of rear driven and front steered tricycles which are driven on two
back wheels, and steered by a front wheel. These attachments consist of skates or
runners to attach to frames or forks of cycles for them to run on, and false rims or
driving tyres for the purpose of propelling the machines.
To apply this invention to rear driven bicycle. The front wheel of the bicycle
is taken out, a bolt is fastened in place of the hub to keep the forks rigid, and a
skate, or runner A is attached to stays B, which are fastened to front forks.
This
skate should have a curved blade, so that the point is not plunged into the ice
when turning, and it should meet the surface of the ice as nearly as possible in a
direct line with the steering pillar. Another skate or runner C is attached firmly
[Price 8d 1

page_text: to stays F, which are fastened to the backstays of the bicycle by collars D, and nuts
and bolts or otherwise, and should be made to allow of adjustment in order to
regulate the pressure on false rim or driving tyre, which will be hereafter described.
Both skates should be made detachable from their stays in order that different
patterns may be used for ice and snow. The back skate should run as near the
hind wheel as possible.
The hind wheel of the bicycle is fitted with a spiked driving tyre or false rim E.
This tyre is made of some elastic material (as wood) and is a little larger than the
rim of the wheel to which fitted, and to which it is fastened by canvas or other
material laced round the rim or otherwise fastened. The driving tyre is also fitted
with spikes G of a semicircular (or other suitable) form, which are set crosswise
on the tyre to allow a side movement to the hind wheel, on account of the skate
not following in exactly the same track with it in turning.
Before fastening on the driving tyre the ordinary tyre should be removed where
detachable, deflated if a pneumatic tyre cemented to rim, or if a cushion, or solid
tyre, the driving tyre can be fastened over either of them. The driving tyres can
be made of two strips of some elastic wood, with a strip of canvas passing between
them, the whole screwed together by the driving spikes. The back skate should
be so adjusted that the driving tyre presses on the ground with sufficient force to
propel machine, when the rider uses the pedals, and a space should be left between
the driving tyre and the rim of wheel, to allow for inequalities in road.
:
To apply this invention in the case of a rear driven and front steered tricycle, a
skate A is substituted for front wheel as in a bicycle both hind wheels are fitted
with the false rims or driving tyres and two other skates C are fastened by stays F
to frame of machine, to run beside each hind wheel.
The semicircular driving spikes are not required for tricycles, but they can be
made pointed or otherwise.
The back skates should be adjustable to regulate pressure on driving tyres, and
the ordinary tyres can be treated in the same manner as in the case of a bicycle.
The driving steering and management of both bicycle and tricycle sledges will be
exactly the same as for bicycles and tricycles without sledge attachments.
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.) The mounting of a rear driven and front steered bicycle on two skates
which follow in a single track.
(2.) The mounting of a rear driven and front steered tricycle on three skates in
the manner described herein.
(3.) The invention of flexible spiked driving tyres for propelling bicycles and
tricycles on ice and snow, when mounted on skates or runners.
Dated this 1st day of September 1896.
