Specification.
Improvements in 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 pertains to the construction of, and detail improvements in, cycle.
or velocipede saddles, and consists in the first part, in the construction of the
supporting framing, and in the under or base framing; secondly, in the dispositions
of the levering springs, which admit of the saddle moving in a vertical direction,"
and at the same time, bringing taut the material composing the seat; in the third
part, to the pin boss, whereby the saddle is affixed in position, and adjustment of
tilt given, by the turning of a nut; in the fourth part, to the construction and
fitting of the tension, and front spring or framing rod affixing means of which the
parts are made interchangeable, and the whole fitted up mainly without rivetting,
screwing or otherwise.
In carrying out my invention of the first part, I support the front of the seat of
a saddle, upon the inner terminal ends of the upper arms of forwardly and vertically
directed loop coiled springs, whose lower terminal ends are directed inwardly into
horizontal members, parallel, or nearly parallel with the underside of the seat of
the saddle, and terminating in a looped eye, disposed at a short distance inwards of
a vertical line dropped from the back of the seat of the saddle.
The upper branches of the said loop coils are connected to the front underside of·
the seat, through the intervention of an end bracket, having a tension pin through
it, whose outer and plain stud end takes within a hole, made transversely through
the lower part of a hanger, whose base is connected by rivetting to the said seat.
The framing supporting the back of the saddle, consists of pot-hook shaped rods,
directed obliquely downwards from the said back, and past the middle of the base
of the other framing, and with the return ends of them, bent into vertical loop coils,
and their middles coming about opposite the rods of the base framing of the other
part.
The metal of the said last-named coils, is then directed upwardly, and then
downwardly into an inverted bridge, and terminating in a single loop, coming
coincident with the loops of the frame member rods above it, and which are coupled
together by a pin passing through the said loops.
Thus, the base and under framing is of a compound order, with the longer limb
members directed inwardly, and passing each other, and with the lower or base
members additionally united together by a cross bracket.
The inverted bridge or bow shaped part is embraced or clipped by the top and
bottom claws or bearing surfaces of an ☐ pin boss.
.

page_text: By making the connection of the two framings beyond or rearward of the middle
of the saddle, and by disposing the lever springs or coils of the back framing
forward of the pin boss, collateral action of the framings is attained, combined
at the same time with automatic seat tensioning.
The said framings rise and fall alike unto parallel motion members, whilst the
seat is kept constantly taut.
In carrying out the second part of my invention, I employ in addition to the sail
general framings, a base framing, in which case, the lower members of the front
coiled springs are made shorter, and are connected by a common loop, to the front
of an inverted-trough-shaped sheet or cast metal base framing, curved downwardly,
and slightly upwardly to a little beyond the pin boss, which is fitted within the
trough, and with a crown stalk of it passing through a long hole or slot made in
the top of the said bracket, which is curved to give the necessary tilt.
The terminal lower ends of the members of the coils of the back framing rods
take into horizontal sockets on the two opposite sides of the bracket, nearly in a
line with the said socket, so that by the arrangement of the levering springs, an
increase in the length of the levering arms is obtained thereby.
In carrying out a modified arrangement of this last named form of my invention,
I make the said base framing trussed, or of a girder formation, alike unto a former
Letters Patent, but with the said girder being in the form of a wedge, with the
thicker part terminating at the L pin boss, whilst the other parts, which have ears,
when turned over or turned up, confine, and partly secure the stand-side members of
the frame rods in position.
In carrying out my invention of the third part, I construct the più boss.as
follows:-
I take a bridge and bifurcated body part, with the terminations of the bifurcated
branches respectively, connected together by a crown, with the undersides of the
same sliaped to the contour of the top of the pin.
Fitted between the branches of the said bifurcated body part, whose opposite
side members are pivoted at their lower ends to the bottom member of the base
framing, is a bossed eye, of a greater internal diameter than the L pin, and with
the said eye in position coming coincident with the arched or gapped from the
bottom portions of the body member, and which bossed eye has directed upwardiy
from its middle, a crown screw, which takes through an elongated hole or eye, of a
convexed or outwardly bowed part of the top member of the base framing.
Taking upon the topside of the crown of the bowed part of the framing, and
surrounding the crown screw, is a thick underside curved washer, and upon the end
of the crown screw, is a screw nut, which when screwed home, draws the bossed
eye upwardly, and the pin boss against the inside crown of the bridge of the
bifurcated member, hence the affixing of the saddle to the L pin.
Besides affixing the saddle, the screwing up of the nut also affixes the adjustment
of the tilt.
In carrying out my invention of the fourth part, which consists in both tensioning
and spring or frame rod affixing means, I fit to the end of the base framing a plate
or table, having a screw pin directed upwardly through its middle, and through
the intervention of which, by metal displacement, the said table or plate is affixed
to the said framing.
Fitted upon the top side and upon the opposite boundary edges of the plate, is a
slide rest, having a longitudinal gap formed within its middle, and a tension screw
taking through a neck or boss at its outer end, so that on the said screw being
forwardly rotated, its extreme tip impinges upon a hanging front part of the table
or plate, and by which means the slide rest moved forwards.
Adjacent to the edges on the opposite sides of the slide rest, are grooves or
channels wherein the stand-side members of the coiled spring take their bearings,
and fitted upon the top sides of the said stand-side ends is an underside grooved
plate, alike unto the grooves in the slide rest, and adapted for the standside
members to lie within.

page_text: This plate is threaded upon the upright screw pin, and the whole affixed by a
screw nut taking upon the said pin.
By constructing and arranging the said parts in manner as described, the
tensioning is easily fitted, and the members of the springs readily affixed.
In the
pin boss, instead of the bifurcated body part turning upon pivots, it
may be made to slide.

Improvements in Cycle Saddles.
1 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 pertains to the construction of, and a detail improvement in a
part of cycle or velocipede saddles viz., the means of attaching the L-pin boss to the
saddle framing.
Figure 4 of the accompanying drawings represents partly in longitudinal vertical
section, and partly in elevation, a hammock or suspension saddle fitted and provided
with supporting framings an attachment boss constructed and arranged according to
one form of my invention.
Figure 2-represents an underside plan of the same, showing the dispositions of the
levering-rods-and-levering springs relative-to-each other and to the saddle-seat
respectively, and how the front underside-and-the-rear-underside-members-are
coupled-together by an-eyed cross bar, and how the terminations of the rods-com-
posing the said front and rear members are-extended-or-prolonged-into-attachments
to which the boss of the L-pin-is attachedly and detachedly connected.
Figure 3 represents a transverse vertical section upon the dotted lines-A-B
Figure 1.
The front of the seat-a of the saddle, is connected-through the intervention of the
bracket-b-and-tension-c, to the upper levering arms d', of upright loop-coiled
strings-d, arranged side by side, and with the lower arms d';-which-constitute the
front base framing, having their inner-ends-d³, directed through an eye e', of a
Interally-disposed tie-piece-e, and with the extreme-terminal-ends-d', prolonged
beyond-the-middle of the said seat; and connected by a pin and looped end, to like
looped-ends-f-of-return-extensions or limbs /1, of levering-loop-coiled springs f³;
having base framing members, provided with curved backs, connected by loops f";
to the extreme rear underside of the saddle-sent.
The connection of the fore part of the levering arms to the tension is made by a
eross-piece-d', so that through the bracket b, and the cross piece d'united by the
tension-c, u-suspension connection is made.
Portions of the members /'; lying adjacent to the loop coils pass-through-eyes
or holes of the tie-e, thus completing the tying together of the fore-framing
rode d'f'
It will be seen that the loop members, form-the-joint-upon which the rear
framing parts of the seat of the saddle turn, and that the said loop coils/³, are
disposed at a distance forward of the saddle attachment-means. Thus assuming the
line-a-a-is-the-centre of the saddle-support, then the return ends of the loop
coils, are disposed in the came direction, but at distances from each other.-By
such an arrangement, increased leverage of the mountings, or the rods constituting

page_text: .
the mountings, is attained, and further, the said frame rods with this added leverage;
are tied or coupled together in manner that the same move in unison, and collaterally
with the up and down movement of the cent.
Figure 4 represents a complete longitudinal vertical section of a saddle-constructed:
mounted and provided with improvements made according to a further form of my
invention.
The lower limb members of the creet loop coiled springs, which form the resilient
mounting of the-front-of the-seat, are moved collectively by the-tension-disposed-at
the front part of a built-up or trussed framing, which is fitted-with-a-particular
construction of boss, whilst the inner terminal ends of the loop coiled-springs, which
come-forward of the centre of the L-pin-boss-(which is the attachment) are connected
rearwardly of the L pin-boss, hence a double leverage, or an added leverage, which
inereases the resiliency of the framing.
Figure 5 represents a portion of the tension.
Figure 6 is a transverse section upon the dotted lines CD Figure 4, and Figure 7
is a transverse section of the L-pin boss and framing upon the dotted lines E F,
also of Figure 4, showing how the arm of the pin is doubly gripped, viz., between
the upper portion of a bifurcated swivelling member, and the lower portion of the
eye of the clamping ring.
a is the seat of the saddle, d are loop coiled springs, having upper levering arms d,
with terminal eye loops ds, which are connected by the bracket b, through nuts c, to
the front underside of the seat of the saddle.
The other and lower levering arms d², have their terminal ends d', connected to al
sliding tension, by a clamping plate g³, with seatings on its underside coincident
with the seatings on the top side of the sliding part g.
This sliding part g, has a returned foot end y', and is kept to a base plate g³, by
a ping, which passes through slots g', g³, of the parts 9, and g², respectively.
is a screw pin, taking through a screw box g, of the fore part g, and with the
end of the said pin coming against the tail end g; of the base plate g³, so that by
turning the screw h, the tension of the saddle seat is either increased or relaxed.
In the rear part framing, are rod members, with curved outer ends f, and
having loop coiled springs ³, forward of the L-pin boss i, and with the terminal
and second levering members f¹, of the said springs, being connected to a pin or
pins carried at the rear part of the base framing j, consisting of two side
members, united together by cross members, or by pins and sleeves, or by their
equivalents.
To prevent the rotation of the end connections, I fit or provide them with
embracing caps m, (shown separate) which clip the framing member, and also
the rods.
The pin boss i, consists of à bifurcated or forked upright rocking member i²,
slotted or gapped to receive the L più limb or support k, and mounted at its lower
part upon pins or centres ³, whilst between the branches of the said rocking or
adjustable member, which has upper abutments or seatings, is a swung or
suspended ring, having a stalk, nut 7, and rest suspension washer .
The said clamping appliance, thus called the boss, is located between the side
members, of the base framings, whose top sides have concave-convex rises ³,
which are embraced by the adjacent parts i, i", respectively, so that on the saddle
being adjusted to the required tilt by the clamping appliance describing an are
about its centre of motion, by screwing home the nut i', the said clamping appliance
is both secured to the saddle, and the saddle, through its framing, to the pin or
member k.
Figure-8-represents a modification of the arrangement Figure 1, and consists in
making each of the fore and aft frame members, with supplementary levering
members and the looped coiled springs and connection members, from-out of a single
length of-rod-metal.
Thus, a is the sent of the saddle,-d-are-looped coiled springs at front; d'-top levering
arms, d² lower levering arms-and-base traming, /³ the loop coiled spring forward of

page_text: the attnehment, d';:/ `-attachment-limbs,/-primary trametevering members, andƒ the
eurred back.
Figure 9-represents in longitudinal vertical-section-n-still-further-modified-form-of
my invention Figure 19-is-an-underside-plan-of-the-same-and-Figure-11-is-a-erØss
section-on-the-dotted lines-G-H, Figure-0.
a-is-the-seat-of-the-saddle;--erect loop-coiled-springs-at-front,-with-upper-and
lower-levering members or arms-'-'-the-upper-ones--suitably connected-aa
described;-und-the-lutter-connected by looped-ends d'; to a base framing
attachment-j-tronghed-in-its-construction,-and-with-portions-of-the-upper-sides
slotted: The rear part-of-this-said-inverted-trough framing-is-enlarged-or-widened
out-into-n-semi-clip-;-whilst the fore-part-of-the-said-widened-ent portion; has
fixedly connected within barrel-terminals-j", lower levering-ends-;-of-coiled
springs--made by the-bending of n portion of the metal forming the framing
rods:
It will be seen that the top side of the said framing-j-is-conenve-convexed-from
the-outside, so that the concaved-inner-fore part can turn upon the top-side-of-the
L-pin-member for tilt-adjustment.
The-elamping means may be of any approved construction.
Figure 12 represents-a-still further modifiention of the former-arrangements.
a is the sent of the saddle,--7-are--loop-coiled-springs at front, with levering
arms-'-d² the former suitably connected-to-the-fore part-of-the-underside of the
saddle-sent ns-before, and the ends of the latter-united-or-connected-to-the-fore-part
framing, with a convex-conenvo adjustable tilt-part-3-terminated-by-a-rear-eross
end-, having pins or their equivalents", directed from them, and from which the
terminal ends of the supplementary levering-arms-are-connected;-and-with-the-loop
springs-, disposed forward of the saddles connection-means-(not shown) whilst-fure
frame-rods or levering arms disposed in the same-relative-directions-as-the-supple-
mentary levering-and-return-arms/'.
