Improvements in the Construction of Springs for Carriages
and other Vehicles.
JOHN UTBER BURT 27 Swinton Street Grays Inn Road London Coach Builder
do hereby declare the nature of this invention to be as follows:-
My invention consists in constructing the ordinary Cee Spring and attaching to
the front end a half elliptic, which I leave loose at the back end to allow for extension.
The loose end is attached to the Cee Spring at the back end by rolling an iron in
the plate & is connected by Couplings to the half elliptic. From the top centre
of the half elliptic I attach an eye which receives a brace the said brace passing round
the Cee Spring & fixed in the ordinary manner.
I can also put an Eye in the top end of the Cee and connect it to the top of half
elliptic by a metal, leather or other brace, thus doing away with the ordinary Cee
Spring Brace.

I, JOHN UTBER BURT, of 27 Swinton Street, Grays Inn Road, London, carriage
manufacturer, 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:-
My invention relates to a construction of carriage spring which combines the
advantages of the two kinds of springs usually known as the elliptical spring and
the C spring, whilst it prevents that unpleasant swinging movement of the carriage
which results from the use of the C spring alone.
Fig. 1 of the accompanying drawings represents in side view a spring according to
my invention. One part A is a C spring which is combined as shewn, with part B of
an elliptical spring. Another part C of the elliptical spring, which may be com-
paratively weak as shewn, is jointed to B by an ordinary eye joint at D and by a
link or shackle at E. To the upper plate of the spring C is attached at F the strap G
which extends along the outside of the C spring A. Owing to the connection at E
of the spring C to which G is attached at F the unpleasant swinging movement of a
carriage hung from an ordinary C spring is prevented, whilst the ease resulting from
the elasticity of the springs is maintained.
Instead of carrying the strap G around the C spring A as shewn in Fig. 1, the
C spring A may be made as shewn by Fig. 2 with an eye at a connected to F by a
strap or link g.
As the form of the parts B and C corresponds with that of the elliptic springs
usually employed, these may be removed from an existing vehicle and the complete
spring shewn including the C spring A may be substituted for them, the same fixings
to the vehicle serving to hol the substituted spring without alteration.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
The construction and use of a spring for a carriage consisting of a C spring in
combination with an elliptical spring arranged substantially as and for the purposes
herein set forth.
