I, JAMES WESTAWAY, Coryton, Lewdown, North Devon, Commercial Traveller
do hereby declare the nature of this my invention for "IMPROVEMENTS IN
UNDER-CARRIAGE, AND SELF-ACTING BRAKES FOR TWO-WHEELED VEHICLES to be
as follows:
"
Frames are fastened by the sides, underneath the carriage, or shafts to carry
cylinders, pistons, or other material to slide freely. Such moveable part is here-
after termed a "slide." Slides are used in front, and at the back on each side, or
in the centre. To allow the slides to work freely, and to keep the carriage level,
when descending a hill, the frames are fastened in a sloping position. The slides
are fastened to the ends of the springs, or to the centre when cross-springs are
used. The ends of the springs are connected by means of rods or chains to prevent
them [when necessary] from expanding: Brake blocks are fixed to the steps, or
extended arms from the carriage, or shafts, in front of the wheels. When
descending a hill the wheels run forward, by means of the slides, until they reach
the brake-blocks and are thus retarded. The blocks are fixed on hinges & cannot
be depressed in a forward movement. In a backward movement these blocks are
lifted upwards by the wheels, when the pressure is very slight, through the slides
having run their course: The blocks again resume their position when the carriage
is drawn forward.

I, JAMES WESTAWAY Coryton Lewdown R.S.O. Devon Commercial Traveller
do hereby declare the nature of my invention for IMPROVEMENTS IN UNDER-
CARRIAGE, AND SELF-ACTING BREAKS FOR TWO WHEELED VEHICLES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The scroll irons A & B have holes to take the rods C. In D. the scroll iron D 1
and C are made in one piece hinged to the plate E and regulated by a screw F.
The rods C and scroll irons D are permanently fixed to slope towards the front of
the carriage, or raised and lowered by means of a screw G. F. or other arrangement
(When the load is behind the axle, the hinder parts of the rods C are raised, and
when. the load is reduced, or shifted forward, they are lowered, which causes the
wheels to keep their proper position.) The ends of the springs H are forked, and
I to take the axle K on which runs a wheel L.
have eyes
A piston, cylinder, or any other suitable appliance may be attached to the ends
of the springs-Such part is hereafter termed a slide.
When springs M. are used, to which the slides cannot be attached arms N are
fastened to the springs and the slides fixed to these arms. When there are no
springs the arms are fastened to the axle O.
When necessary, the ends of the springs are connected by means of rods, chains,
or other appliances to prevent excessive expansion P.
When the Break Arms are used behind the wheels, short arms Q are hinged to
them and kept in position by springs Q2. The Blocks on these short arms are
depressed in a backward movement, and replaced by the springs when the wheels
move forward.
When the Break Arm R is placed in front, the blocks are raised and thrown off
by the wheels, in a backward movement. When the Break Blocks are placed
behind the wheels, one arm S. is used on each side, pivoted to a lever T. and passed
through a ring or loop on the slide L, or through a guide V.
The automatic movement obtained by the slides may be assisted by means of
a hand-lever W. breeching straps X. foot-lever Y, traces Z. attached to the
under-carriage.
INDEX.

Slides are used before and bebind the axle, to allow the wheels to run freely,
and take a forward position when required, and the balance of the load is regu-
lated, and the weight from the break-pressure is prevented from falling on the
animal's back by the under-carriage moving a few inches forward Sloping rods
are attached to the upper part of the vehicle, which rest on the slides, and keep
the under-carriage in its proper position at all times-Thus when descending
hill, the wheels will run forward, until retarded by the break blocks, and when the
bottom is reached, the sloping rods pressing on the slides, cause the under carriage
to take its former position. The break blocks are on armis, binged either before,
or behind the wheels-when behind, the arms are pivoted to the body of the
vehicle, and attached to the under-carriage, near the ends where the blocks are
placed.
When the wheels move forward, the blocks are drawn against them, before the
slides have run their course.
In putting back the vehicle, the arms being hinged are thrown off by the wheels
revolving backward, and replaced by their own weight, or by a spring.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The concordant action of the under-carriage by slides moving on rods sloping
forward.
2. Arrangements for regulating the slope of the rods as required by the weight
and position of the load.
3. The automatic movements of the Break Arms.
