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 for IMPROVEMENTS IN AND CONNECTED WITH SPRINGS FOR SEATS OF ALL
DESCRIPTIONS, FOR UPHOLSTERY AND FOR THE SADDLES OF BICYCLES TRICYCLES
AND OTHER VELOCIPEDES to be as follows:-
In carrying my present invention into effect I take a rod of metal and bend it
into the form of a double spring each half of which consists of a horizontal upper
part having at each end thereof a coil from which arms extend in a slightly
angular direction downwards, each arm extending in a direction contrary to that of
the other and thereby producing somewhat the form of a flattened cross, the inner
arm of each half of the spring is connected to the corresponding arm of the other
half of the spring by a cross rod formed of the continuous rod or wire of which
the spring is formed, the other arms are each formed with an eye or loop through
which a cross rod or bar is passed.
These cross rods or bars are supported in loops of leather, india rubber, or other
flexible material or in loops of metal lined with any suitable soft or flexible material,
such loops being fixed to any suitable parts according to the purpose to which the
spring is applied.
The seat or saddle is fixed to the horizontal upper parts of one or more springs
constructed as above described. If desired a double set of these springs mounted
in a similar inanner may be arranged one above the other in which case the lower
spring or springs will carry a cross board or bearers on to which the upper springs
will press when more weight is applied to them than they are constructed to bear.
If desired, each half of the spring may be separate from the other and the lower
supporting arms may be otherwise held than that above described.
In lieu of webbing and of springs for the seats of chairs and other articles
carried by springs as above described, I employ lengths of wire formed at each end
with a loop or eye or other suitable fastening means and at intervals along their
length with coils or loops the axes or centres of which are in a direction across or
transverse of the general direction of the wire.
Springs of the character last described may be employed in combination with
the springs herein first described or separately therefrom for various purposes.

invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-

The seat or saddle is fixed to the horizontal upper parts of one or more springs

If desired each half of the spring may be separate from the other and the lower

And in order that my 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.
Figure 1 is a side view of a spring constructed according to my invention showing
the saddle connected thereto; Figure 2 is a plan thereof with the saddle removed
and Figure 3 is a transverse section showing the clip in position for fixing the
saddle to the spring. Figure 4 is a side view and Figure 5 a plan illustrating a
modified form of spring and Figure 6 is a sectional side view and Figure 7 is an
underside view representing two springs of form similar to that shown at Figures 4
and 5 employed to support the seat of a chair.
In all the figures like parts are marked with similar letters of reference.
In carrying my present invention into effect, I take a rod of metal and bend it
into the form of a double spring each half of which consists of a horizontal upper
part a having at each end thereof a coil b from which arms c c extend in a slightly
angular direction downwards, each arm c c¹ extending in a direction contrary to
that of the other and thereby producing somewhat the form of a flattened cross, the
inner arm c of each half of the spring may be connected to the corresponding arm c

page_text: of the other half of the spring by a cross rod formed of the continuous rod or
wire of which the spring is formed 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 c³ to
receive a bolt or cross bar d to connect the spring with the head or other suitable
part of a machine or to any desired place whilst the supporting arms c¹ may be
passed through and fixed within transverse holes formed in a shaft or axis e
supported in a bearing f. In figures 1 and 2 the bolt or cross bar d is shown as
adapted to connect the front part of the spring with the head of the machine whilst
the bearing f is carried by an arm g¹ rising from a clip g which may be fixed to
the backbone or framing of a machine.
If desired the outer ends of the arms c¹ may also be formed with eyes c² to
receive a bolt or cross bar d, and these cross bars or bolts & may be supported in
loops of leather, india rubber or other flexible material, or in loops of metal which
may be lined with any suitable soft or Hexible material, such loops being fixed to
any suitable part according to the purpose to which the spring is applied.
In the modification abown at Figures 4 and 5 the bolts or cross bars d and e are
shown carried by bearings f at each end of a bar h which is provided with a
socket h¹ to fit a supporting bar or rail to which it is fixed by a set screw h³ whilst
in the modification shown at Figures 6 and 7 the bearings fare carried by a plain
flat plate or bar h which is formed with holes by which it may be screwed to any
desired place. In Figures 6 and 7 I have represented two of the above described
springs as being employed to support the seat of a chair to which the back ¿¹ is
rigidly fixed by which means a person seated on the chair is enabled to assume any
desired position within certain limits.
When springs constructed as herein before described are employed for supporting
the saddles or seats of velocipedes, such saddles or seats are fixed thereto by clips j
and bolts and nuts j¹ or by other suitable means.
Since filing my provisional specification I have discovered that the arrangements
therein described of mounting double sets of springs one above another and of
employing lengths of wire having coils formed along the length thereof in lieu of
webbing and springs for the seats of chairs and other articles do not possess such
an amount of utility as to render it advisable to retain any claim any claim thereto,
and I therefore desire to disclaim and I do hereby disclaim such arrangements.
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
1. A spring consisting of a horizontal upper part a having at each end thereof a
coil b from which arms c c¹ extend each in a direction contrary to that of the other
and so as to cross one another substantially as herein shown and described and for
the purpose stated.
2. A double spring of the character herein described formed of one piece of
metal bent into the required form or of two parts or halves connected together in
manner substantially as herein shown and described and for the purpose stated.
