Cycle Saddles.
I, JOHN BOULTBEE BROOKS, of Great Charles Street, in the City of
Birmingham, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to detail improvements in cycle saddles, such for example
as the tensioning means and the under metallic framings.
The object of the first part of my invention is a strong and light tension pin, of
which the threads are not liable to become injured by use, whilst the principal
object of the second part of my invention is the prevention of the tucking of the
seat and forming at the same time a stayed but resilient framing, which
by jointing the ends of the members of a two-high and double sided frame to
effected
depending and fixed brackets carried upon the front and back undersides of the
saddle seat.
In carrying out that part of my invention relating to the tension means, the
screwed pin is of the cross section of an upright double-headed axe, or in other
words, the section is circular but with the opposite sides deeply channelled so as to
form the middle part of the pin with a concaved waist, which pin passes through a
like shaped hole or piercing formed through a bracket carried at the front ends of
the framing rods. This hole or piercing has top and bottom clearance for clearing
the top and bottom wormed edges of the pin so that the said pin slides in the
bole without the wormed parts coming into contact with the metal of the
bracket.
The outer end of the pin is formed into a plain shank which takes into a like
plain hole in the hanging bracket depending from the underside fore part of the
seat, with a stop collar coming near the said end. A nut takes upon the screwed
part of the pin forward of the bracket carried at the ends of the rods.
In carrying out one form of the second part of my invention, the back and front
undersides of the saddle have each a pair of depending fixed brackets or hangers,
to each of which the ends of a pair of parallel wires constituting one of the sides of
he frame are jointedly connected.
Thus the two-high and separated rods which form one side of a trussed framing
re horizontally and pivotedly connected at their ends to the hangers or brackets.
The four members of the frame are braced together by an L pin boss which
omprehends the whole of the said wires, which can only move together and with
parallel movement in consequence of the joint connections being separated and
ach wire being constrained to move in different directions upon their joints.
The framing extends from fore to aft of the saddle seat and the members may
ave intervening loop coils to give great resilience whilst still retaining the
gidity.
The ends of the wires, instead of being directly jointed to the hangers or
rackets, may pass horizontally through joint holes in them and then partake of
e figure of loop coils, with their free ends abutting against a support.
The levering of the rods upon the brackets is occasioned by the connection ends
ereof being jointed to separated parts of the said brackets.
Instead of pivoted joints, 1 may employ yielding connections.
In carrying out a further form of this part of my invention, the back ends of the

page_text: two-high and separated rods of each side may be connected together by a pin, with
a bracing plate coming between the pin of one side and the pin of the other, whilst
two coiled springs come between the braced together back ends of the sides of the
framing and the underside of the seat:
The front end of the lower member of each side of the framing is jointedly
connected to a fixed and depending bracket supported from the tension pin, whilst
the front end of the upper member of each side is formed into a ring which
embraces the bracket with an interlocated rubber seating or block thereby forming
a rubber or yielding joint.
Running immediately underneath the saddle seat from the extreme back to the
bracket are two stays or wires, with the back ends rigidly connected to the back
plate and the returned forward end passing through an eye or hole made through
the bracket, hence a joint connection.

I, JOHN BOULTBEE BROOKS, of Great Charles Street, in the City of
Birmingham, 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 :-
This invention relates to detail improvements in cycle saddles, viz., in the
tensioning means and the under metallic framings.
The object of the first part of my invention is a strong and light tension pin of
which the threads are not liable to become injured or stripped by use or by the
front of the saddle frame twisting or turning, whilst the object of the second part of
my invention is the prevention of the tucking of the seat and forming at the same
time a stayed but resilient framing, which is effected by jointing the ends of the
members of a two-high and double sided or trussed frame to depending and fixed
brackets carried upon the front and back undersides of the saddle seat.
In carrying out that part of my invention relating to the tension means, the
screwed pin is concave-channelled upon its two opposite sides, or of the section of
a double-headed axe, or in other words, the section is part circular but with the
opposite sides deeply channelled so as to form the middle part of the pin with a
concaved waist, which pin passes through a like shaped hole or piercing formed
through a bracket carried at the front ends of the framing rods. This hole or
piercing has top and bottom clearances for clearing the top and bottom wormed
edges of the pin so that the bracket slides over the whole pin without the wormed
parts coming into contact with the metal of the bracket.
The outer end of the pin is formed into a plain shank which takes into a like
plain hole in the hanging bracket depending from the underside fore part of the
seat, with a stop collar coming near the said end. A nut takes upon the screwed
part of the pin forward of the bracket carried at the ends of the rods.
Figure 1 of the accompanying drawings represents the fore part of a cycle saddle
provided with a tension made according to one of my improvements.
Figure 2 is an underside plan of the same.
Figure 3 is a cross section of the tension upon the dotted liner, Figure 2, looking
from left to right.
Figure 3 represents the frame bracket without the pin.

page_text: Figure 4 is the tension pin and Figure 5 an end view of its shank.
In Figures 1 to 5, a is a non-rotating pin, with its opposite sides a', fluted or
channelled, and with its shank or fore part a³, passing through a like-shaped and
plain eye b, of a bracket b, to which the ends c', of the frame rods c, are fixedly
connected. Now the fore end a³, of this pin (which is of a like cross section as the
shank,) takes through the like-shaped and plain hole d' of a hanger or seat bracket d,
rigidly connected to the fore underside e, of the saddle seat. The pin, between the
fore end and the shank part carries a stop collar a, between which and the frame
bracket b, is a rotatory nut f, which, when rotated for tensioning the seat, draws
the shank through the eye of the frame bracket and the distance between the fore
and rear ends of the seat is increased.
I might add that there are clearances 62, between the screwed top and bottom
sides a, of the pin and the top and bottom sides of the eye b¹, so that the screw
threads never come in contact with the inside of the eye in the bracket.
Figure 6 represents, in longitudinal vertical section a cycle saddle provided with,
counteracting means for preventing the seat from tucking, and constructed and
arranged according to one forn of the second part of my invention.
Figure 7 is an underside plan of the same with parts of the joints in section.
Figure 8 is a front elevation of the front cup bracket which receives a rubber
bearing block for taking the front thrust of both the top wires of the frame.
Figure 9 represents a section upon the dotted lines, Figure 6.
In Figures 6, 7, 8 and 9, a is the seat of the saddle, made fast at its front and
back ends a', a³, to a back plate a³, and a front tension bracket a. Rigidly con-
nected to the said back plate are a pair of hanger brackets b, to which the rear
ends c, d, of the wires or rods c, d, constituting the sides of a double-ended trussed.
framing, are jointedly connected at c, d and which said wires are collectively
braced together at or about their middles by an attachment clip f, for taking upon
the pin or pillar support. The other and forward ends c, d, of the said frame
rods are connected to cross bars c³, d³, the former of which has a stalk c*, passing.
through a rubber cushioning block g, seating itself within the cupped sinking,
of a hanged bossed bracket h, with a middle clearance A, for preventing the stalk c',
from coming into contact with the metal of the bracket. Now the boss d³, has
an eyed knuckle lug d, jointedly connected to a like eyed and knuckle lug h³, by
a cross pin h¹.
Now this hanging bracket A', has a plain eye h³, through which the tension screw
pinj, with a nut k, upon it, passes.
Assuming the boss f, is rigidly connected to the seat pillar of a machine, then
the weight of a rider coming upon the seat causes the ends c, d, c, d, of the two-
high frame rods c and d constituting the trussed framing, and which are separated
further apart at their ends than at their middles, to be deflected or bent downwards
or forced below their normal planes, whilst the middle parts of the frame rods
remain quiescent or stationary relative to the machine on which the saddle is
mounted.
The result is that the top rods c, which form the fulcrum rods, are straightened
out and their normal lengths virtually increased, whilst the lower rods d, are virtually
shortened by their bowing or cambering, and consequent upon this change of figure
of the rods, the hanging brackets are both bodily forced outwardly and angularly
turned on the joints c, and the rubber block g, as centres of motion, and by such
rocking movement their upper ends are turned outwardly and the normal distances
between the said upper ends of the brackets increased, consequently the seat is
kept constantly on the stretch and the tension increased proportionally to the
pressure applied.
By supporting the fore ends of the top rods of the frame upen a rubber block,
flexibility of the front part of the saddle is attained.
In the modification of front bracket shown in Figure 10, the rubber block forming
the joint on which the stalk end of the cross bar turns is dispensed with, and an
ordinary piu joint substituted therefor.

page_text: Figure 11 represents another modification of this second part of my invention,
and Figure 12 is an underside plan of the same.
Figure 13 is a front end view of the saddle.
a is the saddle seat, at a tension bracket at the front thereof, j a screw tension
pin passing through a bracket eye a' and whose adjustment is made by a nut a',
whilst the hook end j, of the pin takes over the bar h³, of a bracket h, jointed at
to a plate h³, to which the ends c, d, of the members c and d, of a trussed framing
are fixedly connected, whilst encircling the pin he, made fast to the plate h, is a
rubber cushioning pad g, lying within the sinking ', of the plate h. fis the
attachment boss, and c¹, d' are joint loop coils, whilst c, d, are like joint loop coils,
the end termination of the wires or rods being made fast to the skirting plate a³,
made fast to the back part a¹, of the seat.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. A tension-for the seats of cycle saddles, consisting of a non-rotating and
collared screw pin, channelled upon its two opposite sides, and with the shank part
taking through a like-shaped and plain eye in the frame bracket, which bracket is
traversed by the rotation of a screw nut on the said pin, substantially as described
and set forth.
Secondly. In cycle saddles, mounting the seats upon fixed front and back
brackets to which the ends of the members of a two-high wire framing, or a four-
wire or double-sided trussed framing are jointedly connected at separated points
substantially as and for the purpose as described and set forth in Figures 6 to 10.
Thirdly. In cycle saddles, the general construction, arrangement and combination
of the parts of the underframing substantially as and for the purpose described and
Bet forth in Figures 6 to 10.
Fourthly. In cycle saddles, the combination with the double joints at the fore
part of the saddle as represented in Figures 11 and 12 or as represented in
Figure 10, of the loop coil joints as set forth in the said Figures 11 and 12.
