Limited, of Great Charles Street, in the City of Birmingham, Manufacturers,
and JOHN HOLT, of Great Charles Street, Birmingham aforesaid, Manager of
Works, do hereby declare the nature of this invention to be as follows:
This invention relates to cycle saddles, and has for its object, first, to provide
a separate tensioning arrangement whereby the rear part of the seat and the front
or peak are independently adjusted or tensioned; secondly, to so support the rear
body part of the seat that sagging is prevented and the weight of the rider is kept
from being thrown onto the peak, and thirdly, to construct the seat in such a
manner that the halves or opposite sides of the same are capable of an independent
yet restrained up and down movement relative to one another.
According to our invention, we employ a pair of spring levering arms swivelly
connected at their after ends to the rear or body part of the seat of a saddle or to
the fore part of a supplementary under seat leather adapted to uphold the top
leather, whilst the other ends of the said arms are evolved into spring coils and are
connected to a bracket capable of sliding upon a non-rotating tension pin, which is
provided with a second nut and bracket for effecting the independent tensioning of
the fore part of the seat. The rear portion of the seat is preferably longitudinally
divided into two independently moving halves which are sustained or upheld by
the inward ends of the spring arms.
In carrying out one form of our invention, the seat or the top leather of the
seat is suspended between the peak plate and the back plate and a pair of separated
stretcher rods are located under the said seat, with their ends connected respec-
tively to the back plate and ordinary tension bracket, through which
latter, a non-rotating but sliding tension pin, whose outer end engages with
the peak plate, passes. This seat-suspension framing may be either attached
to the pillar of a machine direct, or to an under-framing of any approved construc-
tion. Behind the fixed tension-carrying bracket is a slide or bracket with a plain
hole through its middle to enable it to pass upon the tension pin, and to this slide,
the coiled ends of a pair of spring levering arms are connected whilst their other
ends are swivelly secured to separated attachments fitted to the forward end of an
under seat leather, which supports the divided back part of the seat and is also
longitudinally split or divided with the division extending from the inward attach-
ments of the levering arms to near the back plate of the saddle, thus forming two
independent moving sides or halves, which admit of yielding separately to the
action of the rider in pedalling.
Fitting upon the extending end of the tension pin and abutting against the
end of the spring-carrying bracket or slide is a barrel or other nut, by the rotation
of which the said bracket is propelled or traversed towards the peak, whereby the
independent tensioning of the under seat leather and the rear part of the top seat
is effected, leaving the fore or peak part soft or slack, the tightness or taut of
which latter may be regulated, if required by the ordinary tension

page_text: Instead of providing an under-seat leather for supporting the primary seat, the
inward ends of the spring sustaining and tensioning arms may be swivelly and
directly connected at separated points to parts of the seat proper located on opposite
sides of, or near to, the longitudinal division or split, and instead of employing
spring coiled levering arms, we may employ jointed links operated at their
joint ends by springs, whilst we may employ any spring organized links or levers
for upholding the independent sections of the seat.

Improvements in Cycle Saddles,
We, JOHN BOULTBEE BROOKS, Managing Director of J. B. Brooks and Company
Limited, of Great Charles Street, in the City of Birmingham, Manufacturers,
and JOHN HOLT, of Great Charles Street, Birmingham aforesaid, Manager of
Works, 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 cycle saddles, and has for its object, first, to provide an
improved separate tensioning arrangement whereby the rear part of the seat and
the front or peak are independently adjusted or tensioned; secondly, to so support
the rear body part of the seat that sagging is prevented and the weight of the rider
is kept from being thrown onto the peak, and thirdly, to construct the seat in such
a manner that the halves or opposite sides of the same are capable of an inde-
pendent yet restrained up-and-down-movement relative to one another.
According to our invention, we employ a pair of spring levering arms swivelly
connected at their after ends to the rear or body part of the seat of a saddle or to
the fore part of a supplementary under seat leather adapted to uphold the top
leather, whilst the other ends of the said arms, which may be evolved into spring"
coils, are connected to a bracket capable of sliding upon a non-rotating tension pin,
which is provided with a second nut and bracket for effecting the independent
tensioning of the fore part of the seat. The rear portion of the seat is preferably
longitudinally cleft or set down along the middle so as to divide it into two
independently moving halves which are sustained or upheld at front by the
inward ends of the spring arms.
Figure 1 of the accompanying drawings represents a complete longitudinal
vertical section of a cycle saddle embodying our improvements.
Figure 2 is an underside plan of the said saddle, but with parts of the under-
framing forward of the attachment boss, broken away in order to show the disposi-
tion of the pair of spring levering arms which are carried by the tension pin and
are swivelly connected at their inward ends to a supplementary seat leather
disposed underneath and attached to the body or rear part of the top seat leather.
Figure 3 is a cross section of Figure 1 upon the dotted line a.
Figure 4 is a side elevation of the front end of the saddle, with a portion of
the seat leather removed to show more clearly the arrangement of the levering
arms and the means for independently tensioning the front part of the seat and
the rear part with the supplementary leather underneath the said rear part.

figures of the drawings.
a,
In carrying out the form of our invention embodied in the saddle represented in
the drawings, the top leather of the seat is suspended between the peak plate a¹,
and the back plate a, and a pair of separated stretcher rods b, are located under
the said seat, with their rear ends 61, connected to the said back plate a, and
their forward ends 6, terminating in an ordinary tension bracket c, through
which latter, a non-rotating but sliding tension pin d, whose outer end d', engages
with, or is connected to, the peak plate a¹, passes. This seat-suspension framing
may be either attached to the pillar of a machine direct or it may be supported
by means of front and back pillar coiled springs c, upon an under-framing f, of
any approved construction as in the arrangement shown. Mounted upon the
tension pin d, at a point inwards of the bracket c, is a slide or bracket g, with
a plain hole g', through its middle to enable it to pass onto and be movable
forwardly and backwardly upon the tension, pin, and to this slide, the coiled
ends h', of a pair of spring levering arms h, are connected in any suitable manner,
whilst their other and inward ends 2, are swivelly secured to separated attach-
ments such as i, fitted to the forward end j', of an under seat leather j, which
may be secured in position by rivetting its back edges 2, to the back plate in
common with the top proper of the saddle, but the sides j, and the front end j¹,
are free or independent of the said top, the opposite sides a³, of whose broadest
part may be raised, with suitable stuffing included between the raised parts
and the under seat and are separated from one another up the middle by a longi-
tudinal cleft or set down part a³, the leather bottom of which is secured to the
said under leather by means of a series of eyelets such as a, or by rivetting,
stitching or otherwise. The set down middle part of the seat is in the same
plane as the unsupported and independently tensioned part which comes at the
nose end, and may extend from a point adjacent to the swivelling attachments
of the levering arins to near the back plate of the saddle, which is thereby pro-
vided or formed with two independent moving sides or halves a, a8, which are
capable of yielding separately and alternately to the action of the rider in pedal-
ling, but we wish it to be understood that instead of forming a longitudinal cleft
or set down channel along the stuffed or padded rear part of the seat, we may,
where the seat is not so padded, longitudinally split that part of the said seat
which is supported by the under leather, said split being of a like extent to the
channelled part above described.
Fitting upon the rearwardly extending end of the tension pin and abutting
against the back end of the lever-spring-carrying bracket or slide is a barrel or
other nut k, by the rotation of which the said bracket is propelled or traversed
towards the peak, whereby the independent tensioning of the connected-together
parts of the under leather and the rear part of the top seat is effected, leaving
the fore or peak portion a0, of the said top seat soft or slack, the tightness or
taut of which latter may be regulated if required by the ordinary tension nut m,
bearing in the usual manner against the framing bracket.
Instead of providing an under-seat leather for supporting the primary seat,
the inward onds of the spring sustaining and tensioning arms may be swivelly
and directly connected at separated points to parts of the seat proper located on
opposite sides of, or near to, the longitudinal cleft, division or split, and instead of
employing spring coiled levering arms, we may employ jointed links operated
at their joint ends by springs, whilst we may employ any spring-organized links
or levers for upholding the independent sections of the seat.
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: In cycle saddles, the employment of spring levering arms swivelly
connected at their after ends to the front of the body of the seat, or to an under
leather connected to the said seat, and secuted at their other ends to a longi-

page_text: tudinally adjustable tensioning bracket or slide, substantially as and for the
purposes as described and set forth.
Secondly-The combined means herein described for independently tensioning
the body part of the seat and independently spring-supporting the opposite sides
of the said seat, whereby the said sides are made capable of an independent yet
restrained action relative to one another, substantially as set forth.
Thirdly: A double tensioning device for cycle saddles, arranged upon a single
screw pin, substantially as and for the purpose described and set forth.
