PROVISIONAL SPECIFICATION.
Improvements in Velocipede Saddle-springs.
We, GEORGE SALTER of High Street, West Bromwich, in the County of
Stafford, Manufacturer, CHARLES JOHN HOLDSHIP of Bagnall Street West
Bromwich aforesaid, Traveller, and JOHN WALKER of Overend Street, also of
West Bromwich, Mechanic, do hereby declare the nature of this invention to be as
follows:-
Usually the supporting springs, or the pillar springs, interposed between the
framing plates of saddle springs, are attachedly connected to the said plates, or
framing parts, by riveting, or by rivetted pins, passing through eyes, formed from
the terminations of the said springs.
Our invention consists in coiling the ends of the said springs, into screw boxes,
or inside wormed eyes, wherein the worms of screw pins, take, and thereby affix the
said springs to the plates constituting the framing.
By such means, the springs admit of being made interchangeable, according to
the weight or requirements of a rider.
In carrying out our invention, we employ upper and lower frame plates, and
between the back and front ends of them, coiled springs are interposed, whose ends
are formed respectively into eyes or loops, wormed upon their insides.
The worming is formed by the ends of the wire, from which the springs are made,
being tapered; so that on the said ends being coiled into eyes or rings, with the
extreme taper end lapping or lying under the coil or ring immediately above it, an
inside worm is thereby formed, and within which worm, the thread of a suitably
shaped screw, takes, on the same being passed through plain holes in the plates of
the frame as aforesaid.
It will thus be seen, that the helical threads of each of the eyes of the springs,
are formed by the ends of the wire being twisted into two or more' adjacent coils,
thus forming a screw box, or inside wormed eye, which constitutes the means of
attachedly connecting the said springs to their supporting and carrying plates.
We wish it to be observed that the changing of the section of the ends of the
wires forming the springs, may be varied, consequent upon the worm of the screw
pins, employed.
By making the ends of the wires, into wormed eyes or boxes, without tooling, the
springs admit of being changed or replaced when broken.

COMPLETE SPECIFICATION.
Improvements in Velocipede Saddle-springs.
We, GEORGE SALTER of High Street, West Bromwich, in the County of
Stafford, Manufacturer, CHARLES JOHN HOLDSHIP of Bagnall Street, West
Bromwich aforesaid, Traveller, and JOHN WALKER of Overend Street, also of
West Bromwich, aforesaid, Mechanic, 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 :—
This invention relates to improvements in cycle saddle springs, and has for its
object primarily, the forming of the ends of the same into coiled rings or screw
[ Prins 813

page_text: boxes, wherein the affixing screws take, whereby the said screws admit of being
made interchangeable, according to the weight and requirements of a rider.
Figure 1 of the accompanying drawing, represents partly in longitudinal section,
and partly in elevation, a cycle saddle, whose springs are provided at their ends
with, or are terminated by, screw boxes, or internally wormed loops or eyes, made
according to one form of our invention, whereby the said springs, are attachedly
connected to seat frame and base frame respectively.
This said connection admits of the springs, which are interchangeable, being
readily detached, and stronger or weaker ones substituted, according to the weight
and requirements of a rider.
Figure 2 represents the lower part of one of the said springs, with the screw pin,
which passes through an inside and outside wormed bush, removed, in order to show
the outside worm of the said bush taking within the inside thread or rib of the
ring or eye formed at the termination of the said springs, and which rib or thread
winds spirally round the said interior, at a constant inclination.
Figure 3 represents a side elevation of Figure 2, and Figure 4 a plan of
Figure 3, while Figure 5 shows the said end of the spring, without the bush.
Figure 6 represents a section and side elevation of the bush.
Figure 7 is an elevation of the pin.
a is the seat of the saddle, bare framing rods of it, c is a base plate or base
framing, d is a tensioning device, with bracket and connection d, d³, e are pillar
coiled springs, interposed between the seat framing of the saddle, and its base or
carrying plate c.
The terminal ends of these springs are coiled spirally, and at an angle, alike
unto screw threads, so as to form the same into a screw box, wherein bushes f,
worm themselves, on being rotated.
Thus, each of the said ends of the springs are terminated by single, double, or
quadruple coiled rings or eyes e, having continuous ribs or threads, winding
spirally and at a constant angle within their interiors, wherein a bush f, wormed
exteriorly and marked f', which is of the counterpart of the interior of the said
ring or eye, worms itself on being rotated.
These bushes, are tapped with ordinary screw threads for taking the screwed
shanks g, of the screw pins g, for the affixing of the said springs in position
between the framings.
It may be observed that the screw pins of the seat framings are fixed, whilst the
screw pins of the base framings are detachable.
To give flat bearings to the upper and lower coils of the coiled rings or eyes as
aforesaid, the terminal ends of the wires composing them, are ground off level so
as to make the said bearings come at right angles to the springs.
Figure 8 represents one end of a spring, provided with a screw box, or inside
wormed ring or eye, alike unto that represented in Figure 1, but without a bush,
and wherein which said eye or ring, the wormed shank g³, of a screw pin g, of
Figure 9, takes, on the same being turned or rotated.
Figure 10 represents part of a spring, with its end provided with a single ring
or eye, formed by coiling the end of the metal of the spring, through a revolution
and a half, and within the interior of which, the screw pin, alike unto Figure 9,
takes. It will be seen that the spirally winding screw threads, of the pins
employed, have like winding semi-circular channels, disposed between them, which
take the semi-circular inside parts of the coils of the rings, while the ribs take the
divisional parts between them.
It may also be observed, that by changing the cross section of the metal at the
ends of the springs, varying inside shaped screw boxes may be formed.
It wish it to be understood, that the rings or eyes formed by the coiling of the
metal at the ends of the springs, may be internally tapped, to take a finer threaded
screw pin or bolt, than shown in Figure 10.
The wire of which the springs and ends are formed, may be square, or of any
other section..

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First Forming the terminal ends of cycle saddle supporting springs, into
spirally coiled single, double, or quadruple rings or eyes, into which, screw pins,
with pitches alike unto the winding spirals of the interiors of them, take, as and for
the purpose, as set forth.
Secondly-Providing the terminal ends of cycle saddle supporting springs,
with spirally coiled rings or eyes, and inside and outside screwed bushes, for the
purpose of taking the affixing screw pins, as set forth.
Thirdly Forming the ends of cycle saddle supporting springs, of the kind as
described, into spirally directed rings or eyes, which are interiorly wormed, and
constitute screw boxes, or female screws, for the purpose of taking the affixing screw
pins or bolts, as set forth.
