SAMUEL DAVIES 1 Devonshire Street Portland Place W. London County Middlesex
Hotel Keeper do hereby declare the nature of this invention to be as follows:-
My Improvements consist of an arm or connecting rod between the pedal and
handle on which are placed all the parts of the machine.
This arm or connecting rod I generally continue below the axle of wheel to the
lower end of which is fixed on the inside of arm or rod the pin or pivot on which
the pedal rocks.
I sometimes terminate this arm or rod at the axle in that case the Spindle of the
wheel and the pin or pivot for the podal are in a line.
The pedal is shaped to the sole and heel of the boot and rocks or moves up or down
by the pressure of the heel or toe of the rider on the pin or pivot by this means the
balance and progress are assisted.
The Spindle is fixed on the out side of arm or rod.
Above which is placed the guide for a drop pin this pin having its lower end shaped
to the teeth of the ratchet wheel blocks or stops the wheel from traveling backwards,
Thus when the wheel moves forward the teeth of the ratchet lifts this pin the pin
falling back into each tooth by its own weight or by force of a spring.
The ratchet wheel is fixed on the hub of large wheel.
The support for the brake is placed above the outer edge of wheel on the arm:
or rod.
The arm or rod is continued above the wheel the top terminates in a handle.
Below the handle is placed a moveable arm which is connected to and controles
the brake.
The bearings of the wheel may be fitted with balls rollers coned or plain.
There are two machines one for the right side the other for the left.

page_text: I SAMUEL DAVIES of 1 Devonshire Street Portland Place in the County of
Middlesex "Hotel Keeper" 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 :-
My invention consists of an improvement in the wheel stilt with an arm or
connecting rod between the pedal and handle and fixed to the said arm are all the
parts of the machine. The arm or rod I generally continue below the axle of the
wheel and to the lower end of which is fixed on the inside of the arm, the pin or
pivot on which the pedal rocks. If preferable I may terminate this arm or rod at
the axle, and in that case the spindle of the wheel and the pin or pivot for the pedal
will be in a line with each other. The pedal is shaped to fit the sole and heel of any
boot and rocks or moves up or down by the pressure of the heel or toe of the rider,
working on the pin or pivot, by this means the balance and progress are assisted.
The spindle is fixed on the outer side of the arm or rod and above the said spindle is
placed the guido for a drop pin, this pin having its lower end wedge shape and shaped
to fit into each division of the teeth of the ratchet wheel, which blocks or stops the
wheel from travelling backwards. Thus when the wheel moves forward the teeth of
the ratchet lifts the pin, this said pin falling back into each tooth by its own weight
or by force of a spring. The ratchet wheel is fixed on the hub of the wheel. The
support for the brake is placed above the outer edge of the wheel on the arm or
rod and worked by a rod which is continued upwards towards the handle and terminate
with a button or plunger, this said rod has attached a coil spring to force the brake
off the rubber tyre when not required to be used. The bearings of the wheel may
be fitted with balls, rollers, cones or plain or of any other design. The rider requires
two machines, one for the right side and one for the left, so that the machines are
handed. And in order that my invention may be thoroughly understood, I now
proceed to describe the acompanying drawing thereof reference being had to letters
and figures marked thereon.
Figure 1 represents the side elevation of a right hand machine, with the arm or
rod in a perpendicular position from the pedal to the handle and marked B, with
the handle marked A, with the wheel marked H and the ratchet wheel marked I,
the ratchet wheel being stopped from travelling backwards by the pin K, falling
down inside the socket J, and raising the pin K, as the machine advances and the
pedal L on which the rider places his foot. The brake marked F, with the connecting
rod C with the spiral spring D and the button E to press the brake down when
required to be brought into operation by the rider.
Figure 2 is the front elevation of the machine showing the position of each part
attached to arm or rod B and the other portions being hereinbefore described in
figure 1.
.

page_text: Figure 3 is a full size side elevation of the socket J, fixed to the arm or rod B,
with the top of the drop pin marked K which is square at top and the bottom of the
pin marked K¹ is round in section.
Figure 4 is a plan of figure 3.
Figure 5 is a front elevation of the drop pin.
Figure 6 is a side elevation of the drop pin.
I do not limit myself to the particular shape of the machine or size as shown on
the drawings, as they may it is evident be varied without departing from the nature
of my invention, provided it be of such a nature as according to the aforesaid
statement.
Like letters refer to like parts in each of the figures. A the handle. B the arm
or rod. connecting rod of brake. D spring or brake rod. E button headed top
of brake connection rod. F brake. H the wheel. I ratchet wheel. J socket for
drop pin. K drop pin at top. K³ drop pin at bottom. L pedal.
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 :-
:―
First The combination of the machine for the purpose of being used as a wheel
stilt, substantially as herein described and according to the accompanying drawings.
Secondly I claim the combination of this invention to be an improvement on my
invention, of which letters patent was granted to me bearing date November 13th
1884, No. 14969 substantially as herein described.
:
.
Thirdly The combination of the drop pin K and K' working in a socket J, for the
means of dropping into the teeth of the ratchet wheel, to prevent the wheel travelling
backwards substantially as herein described and according to the accompanying
drawings.
