PROVISIONAL SPECIFICATION.
Improvements in Springs for Carriages.
We THOMAS SLACK and JOHN SLACK of the firm of Slack Brothers of Stock-
port Road Longsight, Manchester in the County of Lancaster, Carriage Builders
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct a carriage spring which shall be
perfectly easy in its action and very simple and economical in its construction; our
improved spring will also dispense with the necessity for a perch."
66
The spring is applicable to the hinder part of a four wheeled carriage such for
example as a "Victoria" and is put together in the following manner.
The rear end of the carriage is hung in any well known manner from a
Cee spring, the lower part of which is attached to a bent or curved wrought iron
bar supported upon a semi-elliptical spring mounted on the axle of the hind wheels,
and forming what is known as a 'dummy' spring.
The rear end of this curbed bar or 'dummy' is formed and supported in the
usual manner, but the front end is prolonged beyond the point where it is attached
to the semi-elliptical spring and connected by a suitable bracket or fixture to the
well' or other convenient part of the carriage.
One of these improved springs being mounted at or near each side of the carriage,
will cause the latter to ride perfectly, and the connection to the rigid or 'dummy
part of the spring will enable the usual perch' to be dispensed with and thereby
effect a great economy in the construction of the carriage.

COMPLETE SPECIFICATION.
Improvements in Springs for Carriages.
We THOMAS SLACK and JOHN SLACK of the firm of Slack Brothers of Stock-
port Road Longsight Manchester in the County of Lancaster Carriage Builders
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 object of this invention is to construct a carriage spring which shall be
perfectly easy in its action, and very simple and economical in its construction;
our improved spring will also dispense with the necessity for a "perch" in a four
wheeled carriage.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the drawing hereunto annexed and the following explanation thereof.
The drawing represents in side elevation part of the body and axle of a carriage
with our invention shown as applied thereto.
The improved spring is applicable to a two wheeled vehicle and also to the
hinder part of a four wheeled carriage such for example as a "Victoria" and is
put together in the following manner.
The rear end of the body a of the carriage is hung from a "Cee" spring b by
means of the leather band or strap c and the bracket d or in any other well known
manner. The lower part of the "Cee" spring b is attached by bolts or rivets to a

page_text: bent or curved wrought iron bar e supported upon a semi-elliptical spring mounted
on the axle g of the hind wheels (if for a four wheeled carriage) and forming what
is known as a 66
dummy" spring.
22
The rear end of this curved bar, or "dummy e is formed and supported in the
usual manner, but the front end is prolonged beyond the point ex where it is
attached to the semi-elliptical spring and connected by a suitable bracket. or
fixture to the "well" or other convenient part of the body a of the carriage.
One of these improved springs being mounted at or near each side of the body of
the carriage, will cause the latter to ride perfectly, and the connection to the rigid
or "dummy" part e of the spring will enable the usual "perch" in a four wheeled
carriage to be dispensed with, and thereby effect a considerable economy in the
construction of the carriage.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improvements in springs for carriages consisting in the combination with
a "Cee" spring, of a "dummy" spring both being connected by brackets to the
body of the carriage substantially as hereinbefore described and illustrated by the
drawings annexed.
