Complete Specification Left, 20th Apr., 1896-Accepted, 6th June, 1896.
J, 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 cycle saddles, and consists in the one part, in a new
tension and in the second part in a compound joint of the framing to the front of
the seat.
In carrying out the first part of my invention relating to the tension means, each
side of the back end of the saddle is provided with a loose and sliding bracket arm,
whose after end is secured by bolting or rivetting to the back plate, whilst the
fore part carries outstanding side screw pins which pass through long longitudinal
slots or openings formed from out of an end part of a framing member, between
the extreme end of which and the extreme end of the base framing, the seat springs
come. This bracket arm has connected with it, a tension screw passing lengthwise
with the framing and taking through a hole formed in a turned-out right angle end
of it. A uut takes upon the end of the screw pin and abuts upon the right-angle
part, so that when the screw is rotated in one direction for tightening, the saddle
This tension
seat is distended by the sliding and rear traverse of the bracket arm.
is arranged at each side of the seat and the back end of the framing is fitted with
pillar or other coiled springs for imparting the necessary resiliency to the seat.
That part of the framing which is slotted and carries the back tension is preferably
made from cut out sheet metal. By arranging the tension as described, the spring
is undisturbed or remains erect when tension is put upon the seat.
In carrying out one form of the second part of my invention in connection with
the compound jointing of the seat to the framing, I fit to the front underside of the
said seat, a hooked bracket, with the hook part coming inwards of the peak and
with which the terminal front part of the seat engages.
Thus, the fore parts of the base and under seat framing wires are formed into
eyes or loops and take upon a cross pin, which engages with the said hook bracket,
hence a compound joint.
In carrying out a further form of compound joint, I proceed as follows:-The
teusion is in the form of a screwed pin or stalk, having at its inner end a plate
bracket secured to the front underside of the seat and with the screwed stem
having threaded upon it, a loose cross head or bracket having trunnion or reduced
ends upon which the eyed or looped front ends of double sided under-seat framing
come, as also do the looped inner ends of the top levering arms of loop-coiled
springs whose lower levering arms are made integral with or attached to the two
sided members of the base frame, which have pillar or other springs directed
between their rear ends or a bracing plate carried thereby and the rear ends
of the under-seat framings, which terminate at the rear underside of the said
seat.
Thus the opposed ends of the under framings meeting at the tension have
a double joint, with the loop coils extending forward of the front of the seat.
The eyes or looped parts of the said opposed ends of the double sides come
together.
:
As a further form, the front eyed ends of the under-seat rods take around the

page_text: ends of the cross bracket or head, so also do the inner eyed ends of the branches of
a link or levering arm or arms, whose outer end comes forward of the front of the
seat and is jointed to the terminal ends of a sleigh-runner shaped front of the
base framing. A spring is interposed between the straight part of the base
framing and a bracket.or cross pin coupling together the frame rods rear of the
tension.
As a still further form, the front terminal ends of the seat rods, which are in
double order and extend forward of the front of the seat, take upon the joint or
trunnion ends of the cross head or bracket wherethrough the tension pin passes,
and so also do the terminal eyed ends of the double members of the sleigh-runner
shaped front of the base framing. The screw nut which comes forward of the
cross head or bracket takes its abutment upon the middle of the fore part
thereof.
By double-jointing and arranging the connection of the seat and base framings
as described, tucking of the seat is prevented and freeness of movement attained,
besides stay being given to the spring parts.

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 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 consists in the one part, in a new
system of tensioning, and in the second part, in a new means of suspending or
supporting the fronts of the seats of saddles.
In carrying out the first referred-to part of my improvements, the back of the
seat of the saddle, through the medium of the backplate, is made fast at points to
the after ends of two rods, bars or sliding bracket arms, whose other and inner ends
slide upon the seat framing rods and are connected to screw pin tensions passing
through the end eyes of a framing cross stay and receiving nuts on their ends,
which nuts, when screwed up, give tension to the seat without disturbing the
perpendicular of the back supporting springs.
The back ends of the seat framing members or rods are supported upon the
terminations of the said springs and are disassociated from the back plate or
the seat itself, whilst the fore ends of them are jointly connected to brackets
on the front underside of the seat in common with the base framings, whose
back ends, which are tied transversely together, support the back springs.
Figure 1 of the accompanying drawings represents a cycle saddle with the
framing and tensioning means arranged in accordance with the first part of my
improvements, by which the back supporting springs remain always vertical and
are undisturbed by the act of tensioning the seat, consequent upon the said springs
being disassociated from that part of the seat which is distensible or admits of
change of figure.
Figure 2 represents an underside plan of the saddle Figure 1, with some of the
parts in horizontal section, showing the slots within the sides of the framing (which
may be cut out from sheet metal) and the connections of the tensioning devices
with the sliding bracket arms, whose after ends are fixedly connected to the back
of the seat through the back plate.

page_text: Figure 3 represents a vertical section of Figure 1 upon the dotted line <, looking
towards the front of the saddle.
In Figures 1 to 3, a is the seat of the saddle, jointedly connected at its fore
end a', through the bracket a², and pin a³, to the eyed ends b', of the fore part b³,
of pierced base framings b, whose back ends 63, are braced or tied together and
carry upright pillar springs c, whose upper ends c¹, are connected to and bear upom
the undersides of the terminations d', of the after ends ², of the seat framings d,
which are in double order, alike unto the base framings b, and have their extreme
fore ends d³, jointedly connected by the cross pin a³, to the bracket a', also alike
unto the said base framing b. The said parts d, are broadened out and pierced
with long eyes d, wherethrough rivets or pins d³, do, pass and are fixedly connected
at their inner ends to loose and sliding bracket arms e, whose after ends e¹, are
made fast by rivets e, to the back plate e³, at the rear underside a', of the saddle
seat a.
The pins d, are outwardly connected to tension screws f, which take
through plain eyes g', in the ends 93, of a stay or right-angled member 9, and
receive nuts h, on their extreme ends, which when rotated, propel and repel the
said sliding bracket arms and gives the necessary tension adjustment to the saddle
seat.
The pins de, simply serve as guides for the parts e, in sliding upon the sides of
the seat framings d.
In carrying out one form of the second part of my invention, in which the
framing is compound-jointed to the seat, the tension embodies a screwed pin or
stalk connected to the front of the saddle by a plate bracket secured thereto, and
passing through the screwed eye of a trunnion-ended cross head, the said trunnion
ends working within upright bearings of a bracket secured to and surmounting a.
spring resting upon the base framing whilst a nut takes upon the end of the screw
pin outward of the eyed cross head. Now the fore ends of the base framing,
onward of the pillar supporting spring, whose axis, when projected upwards comes.
just in front of the peak of the saddle, are connected to the cross head on the
tension pin by joint-ended links or arms, whilst the fore ends of the seat framing
rods are made fast to the bracket surmounting the spring as aforesaid.
The framing is connected to the machine by a boss, whilst the ends of both the
base and seat framing rods are connected to each other and to the saddle, and
located between the said base and seat framings are springs of any suitable
type.
Figure 4 represents a longitudinal vertical section of a cycle saddle constructed.
and arranged according to this last part of my invention.
Figure 5 is an underside plan of the same.
Figure 6 is a vertical section upon the dotted lines a¹ Figure 4.
Figure 7 is an elevation of the trunnion-ended cross head separately.
Figure 8 is a side elevation, partly in section, of the cross head bearing

Figure 9 is a topside plan of the fore end of the seat and the compound-jointed.
levering arms connecting the same to the fore part of the framing.
In Figures 4 to 9, a is the seat of the saddle, with the fore end a', fitted with a
tension pin b, whose inner end has a plate &', for its connection to the underside of
the said seat. The screwed part of the pin b, takes through a plain hole or eye c¹,
in a block or crosshead c, having opposite trunnion arms or pivot ends ², which
work in bearings d', of upright arms or ears d², of a bracket d, which has a
depending stalk d³, to which the upper end f1, of the spring f, supported upon the
foreparts g', of the base framing members g, is connected. h is a screw nut taking
upon the end of the tension più forward of the cross head and i are links whose
inner looped ends take upon the opposite trunnions c³, whilst their forward ends
are connected to the extreme front 9, of the base framing members by a cross pin j.
The back of the saddle is supported by pillar coiled springs k, carried by the
back 93, of the base framing and having their upper ends k', abutting against the

page_text: rear terminations m¹, of the seat framings m, whose fore ends m², are made fast in
the bracket d.
Figure 10 represents a modified form of this part of my invention.
Figure 11 is an underside plan of Figure 10.
Figure 12 is a vertical section of the compound joint upon the dotted lines a³,
Figure 10.
Figure 13 is a topside plan of the fore part of the saddle.
The fore part a¹, of the saddle seat a, is provided with a screw tension pin b,
attached to the said seat by a plate 6', and having threaded thereon, a loose
crosshead or bracket c, with a plain hole c¹, therein wherethrough the tension pin
having a nut h, on its end, passes and trunnion or reduced ends c² upon which the
eyed or looped ends d', of the double sided under-seat framings d, come, as also do
the looped inner ends e', of the top levering arms e², of the loop-coiled springs e,
whose lower levering arms e³, are inwardly attached by any suitable connection (or
they may be made integral with) the fore end of the two-high double sided base
framing, between the rear top ends f2 of which, and the back underside a³, of the
saddle seat, pillar coiled springs g, are directed.

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
First. In cycle saddle seat tensionings mounting and supporting the back ends
of each side of the seat framing members upon their supporting springs, with their
other ends connected to the back end of the saddle seat and providing the said
framings or the end parts of them, with fitted and adjustably sliding bracket arms
or rod members, whose outward ends are made fast to the saddle seat, and with
their inward ends connected to the seat framings inwards of their ends, substan-
tially as described and set forth in Figures 1 to 3.
