PROVISIONAL SPECIFICATION.
Improvements in Springs for Carriages and other Vehioles..
1, JOSEPH BIROH, of Stafford Street, Walsall, in the County of Stafford
Carriage Builder do hereby declare the nature of my said invention to be as
follows i-
My invention has for its object improvements in springs for carriages and other
vehicles which are strong and sensitive in action and cheap to construct besides
being less liable to deteriorate in use.
My eliptical springs are composed of a simple top and bottom plate and the ends
of the two plates are brought together or made up in the following manner :-
The top plate is formed at each end on the under side into a box which may be
round or square eliptical or other shape, with an opening inside each end to admit
each end of the lower plate. Inside each box I fit a round or other block of india
rubber or its equivalent having a hole through it and a bolt of brass, copper or
other metal is passed through the ends of the spring and the rubber fastening the
spring securely at each end together. Springs made in this manner will bear a
much greater weight without difficulty.

COMPLETE SPECIFICATION.
Improvements in Springs for Carriages and other Vehicles.
1, JOSEPH BIROH, of Stafford Street, Walsall, in the County of Stafford,
Carriage Builder, do hereby declare the nature of my said 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 has for its object improvements in springs for carriages and other
vehicles which are strong and sensitive iu action and cheap to construct besides
being less liable to deteriorate in uso.
My eliptical springs are composed of a single top and bottom plate and the ends
of the two plates are brought together or made up in the following manner: The
top plate is formed at each end on the under side into a box which may be round.
or equare, eliptical or other shape with an opening inside each end to aduit cauh
end of the lower plate. Inside each box 1 fit a round or other block of india
rubber or its equivalent having a bole through it and a bolt of brass, copper or
other metal is passed through the ends of the spring and the rubber, fastening the
spring securely at each end together. Springs made in this manner will bear a
much greater weight without difficulty.
In order that my invention may be more clearly understood and easily carried
into practical effect Ilave appended hereunto a double sized sheet of drawings
upon which I have illustrated examples of my improved vehicle springs.
Figure 1 is a side elevation of one form of-my-vehicle spring.
Figure 2 is an inverted plan view of Figure 1.

page_text: Figure
my spring.
Figure 4 is an inverted plan view of Figure 3.
Figure 5 is a side elevation of a modified form of my spring.
Figure 6 is an inverted plan view of the same.
In carrying my invention into practice I form the top and bottom plates A and B
of my eliptical spring from spring steel which may be rolled or forged thicker at
the centre part as shown or it may be of equal thickness throughout in some cases.
I then form the ends a' and a' of the top plate box shaped, which may bo round,
square, eliptical or other shape with the openings a' and a on the inner side of
each end so as to admit the ends 6' and of the lower plate. Inside each box
I fit a gutta percha block or its equivalents with a hole formed through the centro
or thereabouts of each and the bolts or pins D and D' are passed through the ends
of each plate and through the gutta percha blocks thereby securely fastening the
ends of the springs together. In some cases I may use two or more of these
springs placed one inside the other with the wooden blocks E interposed and
secured together by the metal straps or bands and out and as shown at
Figures 3 and 4.
At Figures 5 and 6 I have shown a modification of my spring which is specially
applicable to two-wheeled vehicles. In this case I form my springs from two or
more, by preference three, plates of spring steel F, F and F and near the ends of
the plates F and I form the ears or projections and f which are bent over.
I then insert the gutta percha blocks C or their equivalents between the plates F
und F and F and F at the parts where the cars or projections are formed and
secure them together by the bolts and nuts f. the wooden blocks E being secured
in the centre between the springs by the nut and bolt f' so as to strengthen or
stiffen them.
It will be quite evident the box shaped ends or the ears or projections may in all
cases bo formed on the lower plate or spring instead of the upper as shown on
the drawings.
Having now particularly described and ascertained the nature of my said inver-
tion and in what manner the same is to be performed I declare that what I
claim is
CLAIMS.
First. The improvements in springs for carriages and other vehicles substantially
na herein set forth and as shown up in the accompanying sheet of drawings.
Second. The vehicle spring shown by Figures 1 and 2 made from two strips or
pieces A and B of sreel or other metal with the ends of the one formed box
shaped to receivo a block or pad cf gutta percha or its equivalent in the manner
substantially as herein set forth.
Third. The vehicle spring shown by Figures 3 and 4 consisting of two or more
springs each made from two strips or pieces A and B of steel or other metal with
the ends of one strip formed box shape either round, square or oval, to receive a
block or pad of gutin percha or its equivalent and secured together in the manner
