page_text: We, ARTHUR THOMAS BOON, of 17 Albemarle Street, St. John Street, Clerken-
well, Watchmaker and ADOLPH RIES, of 59 Hatton Garden, both in the County
of Middlesex, Merchant, do hereby declare the nature of our said invention to be
as follows:-
The object of our invention is to apply springs to carriages and other vehicles
in an improved manner.
In carrying out our invention we apply to each wheel of the vehicle, two plates,
one above the other; the lower plate is fixed to the axle, and the upper plate is
fixed to a convenient part of the vehicle, in a vertical line above the lower plate.
The upper plate has four pins or rods projecting downwards, and passing through
four corresponding holes in the lower plate, the outer or lower ends of the rods
being fitted with nuts. Surrounding each of these pins or rods we fit a spiral
spring, each spring being of sufficient strength to support one fourth of the pressure
likely to be borne by one wheel.
Instead of using single plates, each plate may be divided into two or more parts,
and united, at a suitable distance apart, by cross bars, whereby lightness is secured
without unduly reducing the strength.
The plates and springs are made so as to be readily taken apart for renewing
the springs, or replacing a broken one, at any time.
It will be obvious that our invention is capable of being carried out with many
modifications.
Our invention may be applied to vehicles with any number of wheels.

We, ARTHUR THOMAS BOON, of 17 Albemarle Street, St. John Street, Clerken-
well, Watchmaker, and ADOLPH RIES, of 59 Hatton Garden, both in the County
of Middlesex, Merchant, do hereby declare the nature of our said invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of our invention is to apply springs to carriages and other vehicles in
an improved manner.
In carrying out our invention we apply to each wheel of the vehicle, two plates,
one above the other; the lower plate is fixed to the axle, and the upper plate is
fixed to a convenient part of the vehicle, in a vertical line above the lower plate.
The upper plate has four pins or rods projecting downwards, and passing through
four corresponding holes in the lower plate, the outer or lower ends of the rods
being fitted with nuts. Surrounding each of these pins or rods we fit a spiral
spring, each spring being of sufficient strength to support one fourth of the
pressure likely to be borne by one wheel.
Instead of using single plates, each plate may be divided into two or more parts,

without unduly reducing the strength.
The plates and springs are made so as to be readily taken apart for renewing
the springs, or replacing a broken one, at any time.
It will be obvious that our invention is capable of being carried out with many
modifications.
Our invention may be applied to vehicles with any number of wheels.
And in order that our said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is an elevation, and Fig. 2 a plan view (partly in section) of our invention.
a is the upper plate to which the pins or rods bb are fixed. These rods have
screw threads at their lower ends, and nuts cc fitted thereto for adjusting the
compression of the spiral springs f f.
The upper plate a may be fitted to any convenient part of the carriage, preferably
directly over the axle.
d is the lower plate, to which the axle e may be fitted by any ordinary means.
The spiral springs ƒ ƒ are retained in position by the rods b b and by the nuts c c
as shewn.
The plates a and d receive the thrust of the springs, and the springs yield to
the pressure and vibrations of the vehicle.
Substitutes for the plates a and d may be used, consisting of bars, frames, or
any convenient portions of the carriage, or equivalent devices, for receiving the
thrust of, and compressing the springs; and the position of the axle, may be
varied, according to the construction of the vehicle to which the springs are
applied; and other modifications may be made in adapting our invention to
vehicles of various forms and construction.

page_text: Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
1. The manufacture, use and application of spiral springs ff, guided by rods b b,
and confined between plates or equivalent appliances, and regulated by adjustable
nuts cc, substantially as and for the purposes herein before described and shewn on
the drawings.
2. The general construction, combination and arrangement of the several and
respective parts, together constituting our improvements in springs for carriages
and other vehicles, substantially as herein before described and shewn on the
drawings.
