I FREDERICK KREISLER of Crookhaven in the County of Cork Ireland
Carpenter do hereby declare the nature of the Invention for "A NEW AND
IMPROVED CORRUGATED SPRING FOR CARRIAGES, WAGONS, RAILROAD CARS, OR
WAGONS AND OTHER VEHICLES" to be as follows:-
My Invention consists in constructing a spring for use for carriages, wagons,
railroad cars, or wagons and other vehicles of a single steel plate with a longitudinal
corrugation and the edges of which are bent over and corrugated transversely.
The spring thus formed may be bent, or straight according to the purpose to which
it is applied. Springs so constructed may be used singly or two, or more may.be
arranged apart and jointed together to form one spring.
A spring constructed according to my Invention is lighter in weight and capable
of bearing more strain in comparrison to springs of the same weight as ordinarily
made, and can be manufactured at less cost.

Carpenter do hereby declare the nature of the said Invention for A NEW AND
IMPROVED CORRUGATED SPRING FOR CARRIAGES, WAGONS, RAILROAD CARS, OR
WAGONS AND OTHER VEHICLES and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :—
My Invention consists in, constructing a spring for use for carriages, wagons,
railroad cars, or wagons and other vehicles of a single steel plate with a longitudinal
corrugation and the edges of which are bent over and corrugated transversely.
The spring thus formed may be bent, or straight according to the purpose to which
it is applied. Springs so constructed may be used singly, or two, or more may be
arranged apart and jointed together to form one spring.
A spring constructed according to my Invention is lighter in weight and capable
of bearing more strain in comparison to springs of the same weight, as ordinarily
made, and can be manufactured at less cost.
The accompanying Drawings illustrate a spring according to my Invention.
Figure 1 is a side clevation of the spring.
Figure 2 is a plan of Figure 1.
Figure 3 is a section at X X Figure 1.
These Figures illustrate a single spring, which according to my Invention is
constructed of a single steel plate with a longitudinal corrugation A, the edges a
and sides a of which are bent over and corrugated transversely, the top a² of the
spring being plain. The spring may be bent, as shown in the Drawings, or flat,
according to the purpose to which it is applied, and used singly, as shown, or two;
or more may be arranged apart and jointed together to form one spring.
The springs may be made by stamping under pressure by matrices and dies, or
they may be forged.
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
A spring consisting of a steel plate corrugated longitudinally the edges being bent
over and corrugated transversely, substantially as herein described and shown in
the Drawings hereto.annexed.
