Bicycles, Tricycles, and other Velocipedes.
I GEORGE ILLSTON of No. 214 St. Andrew's Road Birmingham in the County of
Warwick Mechanical Engineer do hereby declare the nature of this Invention to be
as follows:-
:-
My invention consists of improvements in springs for supporting the seats or
saddles of bicycles tricycles and other velocipedes described represented and claimed
in the specification of Letters Patent granted to me dated the 21st November 1883
No. 5474.
In constructing according to my present invention springs for supporting the seats
or saddles of bicycles tricycles or other velocipedes I proceed as follows:-
I will describe my invention in connection with a bicycle. I take four lengths of
light steel rod or wire preferably of a cylindrical figure and I make the middle part
of each length of rod or wire into a circular coil preferably of two convolutions the
ends of the rod or wire remaining straight or uncoiled.
These coils are hardened and tempered in the usual manner. I take four of the
coils described and connect them to a horizontal supporting bar to be fixed to the
backbone of the bicycle. The said supporting bar terminates at each end in a cross
pin having two holes and in the holes of the cross pins the lower ends of the four
coils fit respectively and are fixed by screw pins. The coils are situated vertically
and their ends are turned outwards that the convolutions of the coils are over the
middle portion of the supporting bar and the straight or lower ends of the coils are
over the ends of the said supporting bar and are fixed thereto in the manner
described. The upper ends of the coils are connected to an upper or saddle bar (to
which saddle bar the saddle is affixed) in a manner somewhat similar to that in which
the lower ends are attached to the supporting bar excepting that the cross pins in
holes in which the upper ends of the coils are fixed are not formed in one piece with
or rigidly connected to the bar but are cylindrical and pass through and are capable
of turning in sockets at the ends of the said saddle bar.
By this arrangement the upper or saddle bar is capable not only of yielding to

page_text: vertical pressure but either end of the said bar can yield to any pressure occasioned
by the inclination of the rider's body.
In order to secure lightness in the upper or saddle bar it may be made of two
parallel light steel rods or wires.
Instead of fixing the seat or saddle to the middle of the upper or saddle bar the
said seat or saddle may be connected to the said bar at or near its ends in which case
the said bar forms part of the foundation of the saddle.
The application of my invention to tricycles and other velocipedes differs in no
essential respect from its application to bicycles as hereinbefore described.
Springs for supporting the seats of bicycles tricycles and other velocipedes made
according to my invention are light and compact and are capable of yielding in all
the directions in which it is desirable that such springs should yield.
Dated this Fifth day of January 1887.

I, GEORGE ILLSTON of 214 St. Andrew's Road, Birmingham, in the County of
Warwick, Mechanical Engineer, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to he particularly described and
ascertained in and by the following statement :-
My invention consists of improvements in springs for supporting the seats or
saddles of bicycles, tricycles and other velocipedes described, represented and claimed
in the specification of Letters Patent granted to me dated the 21st November 1884
No. 5474.
In constructing, according to my present invention, springs for supporting the
seats or saddles of bicycles, tricycles and other velocipedes I proceed as follows :-
I will describe my invention in connection with a bicycle. I take four lengths of
light steel rod or wire preferably of a cylindrical figure and I make the middle part
of each length of rod or wire into a circular coil preferably of two convolutions, the
ends of the rod or wire remaining straight or uncoiled.
These coils are hardened and tempered in the usual manner. I take four of the
coils described and connect them to a horizontal supporting bar to be fixed to the
backbone of the bicycle. The said supporting bar terminates at each end in a cross
pin having two holes and in the holes of the cross pins the lower ends of the four coils
fit respectively and are fixed by screw pins. The coils are situated vertically and
their ends are turned outwards, that is, the convolutions of the coils are over the
middle portion of the supporting bar and the straight or lower ends of the coils
extend to the ends of the said supporting bar and are fixed thereto in the manner
described. The upper ends of the coils are connected to an upper or saddle bar (to
which saddle bar the saddle is affixed) in a manner somewhat similar to that in which
the lower ends are attached to the supporting bar; excepting that the cross pins, in
holes in which the upper ends of the coils are fixed, are not formed in one piece with
or rigidly connected to the bar but are cylindrical and pass through and are capable
of turning in sockets at the ends of the said saddle bar.
In order to secure lightness in the upper or saddle bar it may be made of two
parallel light steel rods or wires.
The application of my invention to tricycles and other velocipedes, differs in no
essential respect from its application to bicycles as herein before described.
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.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view, Figure 2 is a plan and Figure 3 is an end view of a
spring constructed according to my invention and suitable for use with a tricycle or
other vehicle provided with an L pin or supporting pillar or rod.
In all the figures like parts are marked with similar letters of reference.
I take four lengths of light steel rod or wire preferably of a cylindrical section and
I make the middle part of such length of rod or wire into a circular coil a preferably
of two convolutions, the ends a¹ of the length of rod or wire beyond the coil a
remaining straight or uncoiled.
These coils are hardened and tempered in the usual way.
I take four of these coiled lengths of wire or rod and connect each of them by one
of ends a¹ to a horizontal supporting har b which may be formed with a suitable clip
to enable it to be fixed to the backbone of a bicycle, tricycle or other velocipede, or it
may be provided as shown in the drawings with a projection 61 formed with a cross
socket to receive an L pin to which it is fixed by the screw 6³.
The said supporting bar b terminates at each end in a cross pin 64 which has two
holes formed transversely through the same and in these holes the lower
ends a¹ of the four coiled lengths of wire or rod fit respectively and are fixed therein
by screw pins c screwing into tapped holes formed in the ends of the cross pins 6*.
The coils a are situated vertically and their ends a¹ are turned outwards, that is,
the convolutions of the coils are over the middle portion of the supporting bar b and
the straight ends a projecting from the coils a extend to the ends of the said
supporting bar b and are fixed to the cross pins 6* thereof in the manner described.
The upper ends a projecting from the coils a are connected to cross pins d' carried
by an upper or saddle bar d in a manner similar to that in which the lower ends a¹
are attached to cross pins 64 of the supporting bar b, excepting that the cross pins d',
(in holes d² in which the upper ends a of the coils a are fixed) are not formed in one
piece with or rigidly connected to the saddle bar d but are cylindrical and pass
through and are capable of turning in sockets formed in bosses d³ at the ends of the
said saddle bar d.
By this arrangement the upper or saddle bar d is capable not only of yielding to
vertical pressure but either end of the said bar can yield to any pressure occasioned
by the inclination of the rider's body.
In order to secure lightness in the upper or saddle bar d it may be made of two
parallel light steel rods or wires formed at the ends to receive the cross pins d¹.
Instead of fixing the seat or saddle to the middle of the upper or saddle bar d the
said seat or saddle may be connected to the said bar at or near its ends, in which caso
the said bar forms part of the foundation of the saddle.
Springs for supporting the seats of bicycles, tricycles and other velocipedes made
according to my invention are light and compact and are capable of yielding in all
directions in which it is desirable that such springs should yield.
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 spring formed of four coils a fixed by their ends a¹ to bars 6 and d substantially
as herein shown and described and for the purpose stated.
