"IMPROVEMENTS IN
in the City of London, Engineer, for an Invention of
TWO-WHEELED CARRIAGES."
PROVISIONAL SPECIFICATION left by the said John Medley Stuart at the
Office of the Cominissioners of Patents.on the 26th November 1881.
JOHN MEDLEY STUART, of No. 11, Queen Victoria Street, in the Ciy of London,
Engineer. "IMPROVEMENTS IN TWO-WHEELED CARRIAGES."
The Invention consists of improvements in the construction of two-wheeled
carriages.
In carrying out my improvements I take a steel bar, of say, two inches by half
an inch soction, and bend it in the direction of its length so as to form three sides
of a square, near the centre of two opposite sides of which I weld on a shaft or axle
for the bearing wheels.
At the two ends of the said steel band are attached springs having an upward
tendency, and at the end of these springs are applied cross springs which are
made fast to the body of the carriage, thus dividing the weight equally over the
steel bar.
.
The upper portion of the carriage is also suspended from the steel bar by means
of a spiral or other suitable spring, thus dividing the weight and balancing the
same. The seats are arranged reversible, either to face each other or in opposite
directions, the door being in the forward or in the back part of the carriage; the
draft is conducted from two portions of the steel bar, say, about a foot above
and a foot below the axle, and so as to converge in one when it joins the shaft.
I also by the same means employ the usual axle, attaching to it a strap of steel
running downwards within, say, a foot of the ground, on the base of which I apply
by hinge joints, springs, and I arrange the carriage with its seals back to back, and
on the sides leaving the play for the axle for larger vehicles.
I make a short axle, say, six inches in length, and attach to it long springs,
the ends of which I bolt on to the side of the carriage in such a manner that the
carriage balances itself. Also I employ a revolving axle with wheels affixed thereto,
the carriage being swung on boxings attached to the main body.

DESCRIPTION OF THE DRAWINGS.
Figure 1 represents an external side view of a two wheeled carriage arranged
according to my improvements; Figure 2 represents one half of a back view, and
Figure 3, the corresponding half of a front view of the same.
Figure 4 represents one half of the underside view of the vehicle; Figure 5 1
represents a sectional inside view of parts of the body; Figure 6 represents a
sectional back view, and Figure 7 a sectional front view of parts of the same;
Figures 9, 10, 11, and 12, indicate parts separately. In each of the Figures the
same letters are used to indicate corresponding parts wherever they occur,
A indicates the body of the vehicle.
B, the bearing wheels; and C, the main axle ; D indicates the shafts to receive the
horse; E indicates the bearing springs by which the body is supported and
connected to the axle C; F indicates the driver's seat, and G the footboard thereto,
whilst H, H, indicate steps to the driver's seat. This driver's seat F is applied so
as to be moveable on the top of the vehicle in order to afford facility for adjust-
ment of the weight of the driver to that of the passengers or their luggage.
a indicates a door applied to the back of the body of the vehicle and b a step to
that door with a wheel b' under it. This step 6 is supported from the back of the
body A by means of the bracket 63; c represents windows in the front of the
vehicle d, corresponding windows at the back, whilst e, c, represent side windows
with ventilators e¹ over them, all which windows may be arranged to rise and fall
at pleasure in the usual way.
The door a is also provided with a window to be raised or lowered at pleasure,
and it is hung to the door pillars by hinges a¹.
The seats inside the body of the vehicle are arranged at opposite sides of the
interior, and I prefer to form them by loose frames, Figure 8, filled in with cane,
or they may be cushioned and held in position by thumb screws or otherwise so as
to be readily removeable for repair or otherwise and replaced at pleasure, or the
seats may be arranged crosswise if desired.
The spokes of the bearing wheels B are indicated simply by the lines B¹ so as to
avoid as much as possible interfering with the parts behind them.
The axle C is bent so as to some extent to form three sides of a square, and the
shafts or axlo proper C' are welded thereto. The bearing springs E are attached to
the upright parts of the axle C as shewn.
The inner ends of the shafts D are tenoned into the bar ƒ forming part of the
front framing of the vehicle, and their connection with the body of the vehicle is
strengthened by the stay irons D', which are in part connected securely by bolts
and nuts to the front of the framing of the body, and thence to the shafts along
which they are continued to the end of them.

page_text: The driver's seat F (shown separately by Figures 9, 10, 11), has a back F¹ to it,
and it is formed with buttons F on the underside of it to pass into slotted
openings F in the upper part of the vehicle formed to receive these buttons, and
then by passing these buttons Fs through the enlarged ends in these openings F³
and allowing the other studs F', also on the underside of the seat F, to pass into
one or other of the holes F, the position of the seat F may be adjusted.
I (Figure 12) is a strap or band to assist the driver in drawing to the door a
when desired without leaving his seat.
An opening with a lid to it may be applied in the roof of the vehicle behind the
driver to facilitate communication with him.
Having thus described my Invention and means which I adopt in carrying the
same into effect, I would have it understood that what I claim is the arranging and
combining parts of two wheeled carriages, as described.
In witness whereof, I, the said John Medley Stuart, have hereunto set my
hand and seal, this Twenty-sixth day of May, in the year One thousand
eight hundred and eighty two.
