follows:-
"
My invention relates to improvements in bearing springs of that class which are
used between the frame and body of a railway carriage to diminish, or prevent, the
transmission of the vibrations or concussions of the frame to the carriage body.
Springs made of India-rubber have heretofore been used for this purpose, but
such springs have not been found altogether satisfactory.
I have, therefore, devised my improved bearing spring which is constructed as
follows, that is to say:-It consists of a hardened or tempered steel-plate corrugated
and bent into an arched form. This plate is, in some instances, covered with
India-rubber, or with felt, or similarly soft material combined with the steel, by
any process which will ensure its permanent attachment thereto. This India-
rubber or other soft covering deadens or diminishes the noise. The arched form
allows the spring to rest firmly and securely with its two ends on the frame, while
its central upper portion forms the support for the carriage-body. By using steel
covered or coated with India rubber or other material I produce a spring which is
more durable and less liable to alteration of shape or other injury than the India
rubber springs hitherto used. Moreover, the corrugated arched formation of my
improved spring allows me to impart to the same a very great amount of elasticity
within a limited space, such as is ordinarily available for the reception of these
springs in railway vehicles. These springs are usually made in width about equal
to the side of the under frame, and in length rather more than the width, but
I may make my improved springs of any desired length.
They are secured to the frame and body of the vehicle by bolts in the ordinary
manner, or by other convenient means.

Improvements in Bearing Springs for Railway or other
Vehicles.
I LOUIS STERNE, of 10 Victoria Chambers, Westminster, in the County of
Middlesex, Engineer, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN BEARING SPRINGS FOR RAILWAY OR 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 relates to improvements in springs such as are commonly termed
assistant bearing springs and are used between the frame and body of a railway-
carriage to diminish or prevent the transmission of the vibrations or concussions of
the frame to the carriage-body.
Springs made of india-rubber have heretofore been used for this purpose, but
such springs have not been found altogether satisfactory.
I have, therefore, devised my improved bearing spring, which I will now proceed
to describe by the aid of the accompanying drawings, in which,
Figure 1 is a plan, and
Figure 2 a vertical longitudinal central section of my improved spring.
Figures 3 and 4 are similar views illustrating a modification thereof.
Figure 5 is a perspective view, and
Figure 6 a vertical longitudinal central section showing, one of my springs
without the covering hereinafter.described.
My improved spring consists of a hardened or tempered steel plate a arched,
bent, 'or corrugated into, the form shewn in the drawings, so that it will rest firmly
and securely with its two ends b on the frame, while its arched portions, at b¹
support the carriage-body. I prefer to cover, the bearing parts of the said plate,
that is to say, the parts which are in contact with the carriage-body and frame,
with india-rubber, felt or similar material, as at c in Figures 1 and 2, which
material is united or combined with the steel by any process that will ensure its
permanent attachment thereto. Or I provide the spring with a surface or
covering d of such material, which entirely encloses the steel plate as shown in
Figures 3 and 4.
By employing steel covered or coated with india-rubber or other soft material as
above described, I produce a spring which is more durable and less liable to
alteration of shape or other injury than the india-rubber springs hitherto used.
The arched or corrugated formation of my improved spring enables me to impart
to the same a very great amount of elasticity within the limited, space ordinarily
available for the reception of these springs in railway-vehicles. Moreover the
india-rubber or other soft covering deadens or diminishes the noise produced by
the vibrations or concussions to which the carriage is subjected when in use.
In some instances, however, I make and use my improved springs without this
covering, as shewn in Figures 5 and 6.
My springs are usually made of a width about equal to the side of the under
frame, and of a length rather greater than the width; but I may make my

page_text: improved springs of any desired length. The said springs are secured to the frame
and body of the vehicle by any convenient means; I prefer, however, to secure
them to the frame by bolts passing through the slots e, and to the body by a bolt
passing through the central hole f.
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 bearing spring consisting of an arched, bent or corrugated steel plate, with or
without the covering or coating of india-rubber or other material, substantially as
above set forth and for the purposes specified.
