PROVISIONAL SPECIFICATION.
Improvements in Two Wheeled Road Vehicles.
I ALEXANDER MONRO Gentleman Oriel College Oxford do hereby declare the
nature of this invention to be follows:-
The body of the Carriage rests on four springs, two being side springs & two cross
springs shackled to the side springs at front & back. The shafts are framed with the
cross piece by two iron T plates in front of the body & behind the Horse. The shafts
are hinged to the front of the side springs outside of the body. This hinge is checked
by the shafts projecting along the spring by the side of the body to about three fourths
of the length of the side spring and there fixed to a spring from each shaft carried
round underneath the bind cross spring to the shackle by which the hind cross spring
hangs, or a spring may be put underneath the body from shaft to shaft fixed to the
body at centre.
COMPLETE SPECIFICATION.
Improvements in Two Wheeled Road Vehicles.
I ALEXR. MONRO Gentleman Oriel College Oxford 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 carriage rests on two cross springs shackled to two side springs & quite free
from any connection with the shafts. The shafts are framed together with the one
cross piece behind the Horse & are hinged to the front end of the side springs. This
hinge is checked by a spring attached to the end of each shaft & fixed to the hind-end
of the side springs or by one spring attached to each end of the shafts & fixed under-
neath the body of the centre.
The shafts are framed to a cross piece G by two iron T plates as shown on the Half
Plan by dotted lines H. J. K. (to which a step may be fixed) similar to the shafts of a
four wheeled carriage & have a hinge with a stay as shown in side view by D. A.
which fits inside of the shackle for the cross spring at A. as shown in end view plan.
This hinge is checked by the shafts projecting back outside of the body to about
three quarters of the length of the side spring A. B. & may be either fixed to springs
attached to the side springs A. B. at B as shown in the side view by E. F. the end of
the spring being held by the shackle of the cross spring at B & which shackle has two
holes in it as shown. (This method is preferred.) Or the shafts may be fixed to a
cross spring attached to the centre of the body as shown by M in the Half Plan.
Having now particularly described and ascertained the nature of my said In-
vention, and in what manner the same is to be performed I declare that
what I claim is.
1st. The shafts to be framed together with the cross piece & hinged to the front of
the side springs. The binge being checked by two shaft springs or a shaft cross
spring. (Which springs or spring are in no away affected by the load of the carriage
and may be termed balance springs.)
2nd. The Body of carriage to rest on four springs, two being side springs & two
cross springs shackled together.

page_text: 3rd. The Horse movement is counteracted, first by the hinge & the shaft check
spring & second by the front cross spring of the body, so causing perfect stability of
motion which is the great aim of this invention.
