page_text: I JOHN HARRINGTON of "The Enamel and Cradle Spring Works" Coventry in
the County of Warwick manufacturer do hereby declare the nature of the said
invention to be as follows:-
The invention has for its object improvements in springs for carriages, and for
the seats or saddles of bicycles, tricycles and other velocipedes and for other seats.
For this purpose I construct a double spring of rod metal each half of which is
formed with a straight or curved upper or central part from which the metal is
bent downwards at each end and is then coiled either for half a turn or for one or
more entire turns after which the metal rod is carried in opposite directions so that
one part shall be directed forwards and the other backwards; when giving only
half a turn to the metal at each end of the upper or central part, the rod is formed
into a long flattened loop at the centre part of the spring the lower part of which
is formed of two parts running in opposite directions, the one part, from the forward
part of the loop extending backwards, and that from the back part of the loop
extending forwards. In some cases when forming the coils with one or more entire
turns, I add to the length of metal extending from one or both of the aforesaid
coils an extra coil from either or both of which the rod is caused to extend forwards
or backwards from the lower part thereof, or when two of such extra coils are
employed the rods may extend in the same or in different directions in which latter
case they may extend towards or away from each other.
The upper or central part of the spring may be at a level with the upper parts
of the coils at each end thereof or the metal rod may be sọ bent as to carry such
upper or central part more or less above such coils.
The two halves of the spring may be formed of one length of rod metal or two
lengths may be used which may be connected together in any suitable manner.

I JOHN HARRINGTON of "The Enamel and Cradle Spring Works" Coventry
in the County of Warwick, 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 :-
The invention has for its object improvements in springs for carriages, and for
the seats or saddles of bicycles, tricycles and other. velocipedes and for other seats.
For this purpose I construct a double spring of rod metal each half of which is
formed with a straight or curved upper or central part from which the metal is
bent downwards at each end and is then coiled either for half a turn or for one or
more entire turns after which the metal rod is carried in opposite directions so that
one part shall be directed forwards, and the other backwards; when giving only
half a turn to the metal at each end of the upper or central part, the rod is formed
into a long flattened loop at the centre part of the spring the lower. part of which
is formed of two parts running in opposite directions, the one part from the forward
part of the loop extending backwards and that from the back part of the loop
extending forwards. In some cases when forming the coils with one or more entire
turns I add to the length of metal extending from one or both of the aforesaid coils
an extra coil from either or both of which the rod is caused to extend forwards or
backwards from the lower part thereof, or when two of such extra coils are employed
the rods may extend in the same or in different directions in which latter case they
may extend towards or away from each other.
The upper or central part of the spring may be at a level with the upper parts of
the coils at each end thereof or the metal rod may so bent as to carry such upper
or central part more or less above such coils.
The two halves of the spring may be formed of one length of rod metal or two
lengths may be used which may be connected together in any suitable manner.
And in order that the said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
At Figures 1 and 2 I have represented a spring in which the central upper part a
is connected with arms c c¹ by half loops b b thereby forming long flattened loops
at the centre part of the spring the lower part of which flättened loops is formed
of the arms c'c' which run in opposite directions and across each others path. The
inner arm c of each half of the spring may be connected, to the corresponding arm c
of the other half of the spring by a cross rod formed of the continuous rod or wire
of which the spring is made as shown by the dotted lines c* in Figure 2 or as shown
by the full lines in-the various figures each half of the spring may be separate from
the other and the supporting arms c may be formed with eyes to receive a bolt
or cross bar d to connect the spring with the head or other suitable part of a
velocipede or to any desired place whilst the supporting arms c³ may be passed

page_text: through transverse holes formed in a shaft or axis e supported in a bearing in
which holes they are held fast by set screws e¹.
The bearing fis carried by an arm g' rising from a clip g which may be fixed to
the backbone or framing of a velocipede. If desired the outer ends of the arms c¹
may also be formed with eyes such as c* to receive a bolt or cross bar d and these
bolts or cross bars d may be supported in loops of leather, india rubber or other
flexible material such loops being fixed to any suitable part according to the purpose
to which the spring is applied.
Figures 3 and 4 represent a spring in which the metal rod from the central
upper part a is bent downwards and then coiled for one or more entire turns b, the
arms c, c, extending inwards in opposite directions and crossing one another's
path. By these means the central upper part a of the spring is raised above the
coils b.
A somewhat similar form of spring is shown at Figures 5 and 6 except that the
metal rod is coiled in the opposite direction from that shown at Figures 3 and 4
and the arms c c¹ extend outwards as hereafter described with respect to Figures 7
and 8. When springs constructed as hereinbefore described are employed for
supporting the saddles or seats of velocipedes, such saddles or seats are fixed
thereto by clips; and bolts and nuts as shown with respect to Figures 13, 14
and 15 or by other suitable means, but when they are applied to carriages a plate
may be employed to connect together the two members of the spring and also to
attach the spring to the carriage.
Figures 7 and 8 represent a spring in which the metal rod from the central
upper part a is bent downwards and the coils b are so made that the metal rod
from the front coil b extends forward and produces the arm c whilst the metal
from the rear coil b extends backwards and produces the arm c¹ by which con-
struction the arms c c³ do not cross each other's path. At Figure 8 I have shown
the central parts a of the two halves of the spring bent inwards towards each
other but in the plan shown at Figure 9 I have shown the central parts a parallel
with each other.
Figures 10 and 11 represent a spring of a similar form to that shown at Figures 7
and 8 except that it is provided with an extra or third set of coils at 6* from which
the metal rod extends forward in the form of arms i which may be provided with
any suitable fixings.
Figure 12 represents a somewhat similar form of spring to that shown at
Figures 10 and 11 but in this case the position of the parts is reversed, the arms i
and c being fixed in the desired position by any suitable means.
Figures 13, 14 and 15 represent a spring in which the front half is formed in a
similar manner to that shown at Figures 7, 8, 10 and 11 whilst the rear part is
completed by a coil similar to the extra or third coil shown at Figures 10 and 11.
The arms may be passed through trunnions e working in bearings g² carried by
the clip g or such arms i may be otherwise supported.
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:
The peculiar construction of springs substantially as herein shown and described,
and for the purposes stated.
