Improvements in the Supports and Securing Attachments of 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 the supports or L pins of cycle saddles, and to the frame-
securing attachments or bosses to be used in connection therewith, and has for its
principal object, a simple sliding attachment which admits of a considerable reach:
in its horizontal adjustment.
According to my present invention, the seat pillar is surmounted by a horizontal
bar, preferably of a dovetail cross section, or the section of a trough with undercut
edges, and with the foot of a block, forming the middle or body part of the
attachment boss and having a like cross section as the inside of the said troughed
bar, capable of sliding longitudinally therein.
This said middle block or body part of the boss has a transverse hole through it."

a pair of frame gripping washers and a gripping cheek strung upon each end of the
said bolt, with the said gripping cheeks coming upon the two opposite sides of the
body and with inwardly-inclined parts of them overhanging and impinging upon
the like-inclined outer sides of the troughed bar, which sides are adapted to
slightly yield inwards on the screwing up of the said nuts, thereby affixing the
middle block to the said trough bar and the saddle framing rods to the attachment
boss.
Thus, to longitudinally adjust the framing through the attachment, or the
attachment along the bar, or to give tilt to the saddle, slacken one or both of the
nuts when the framing gripped between the washers can be slightly rotated to give
tilt adjustment, or the framing can be slid forwards or backwards through the
washers, or the attachment itself can be slid backwards or forwards along the whole
length of the troughed bar to effect longitudinal adjustment, or the whole of the
said movements can be effected at the same time, and after the necessary adjust-
ments have been made, the screwing up of the nut or nuts clamps the gripping.

overhanging parts forcibly impinge against the sides of the bar which are in turn
closed upon the foot of the middle block, hence the affixing of the attachment boss
to the seat support and the saddle to its connection.

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 the supports or seat pillars of cycle saddles, and to the
frame-securing attachments or bosses to be used in connection therewith, and has
for its principal object, a simple sliding attachment which admits of an uninterrupted
traverse from end to end of its support, and of a considerable reach in its horizontal
adjustment.
According to my present invention, the seat pillar is surmounted by a horizontal
bar, preferably of a dovetail cross section, or the section of a trough with inwardly
overhanging sides for the purpose of receiving the foot of a block capable of sliding
longitudinally therein and forming the middle or body part of the attachment boss
and having a like cross section as the inside of the said troughed bar.
This said middle block or body part of the boss has a transverse hole through it
wherethrough a screw-ended pin or bolt having screw nuts at its ends passes, with
a pair of frame-gripping washers and a gripping cheek strung upon each end of
the said bolt, with the said gripping checks coming upon the two opposite sides of
the body and with inclined parts of them overhanging and impinging upon the like-
inclined outer sides of the troughed bar, which sides are adapted to slightly yield
inwards on the screwing up of the said nuts, thereby affixing the middle block to
the said trough bar and the saddle framing rods to the attachment boss.
Thus, to longitudinally adjust the saddle boss or attachment along the bar, or to
give tilt to the saddle, slacken one or both of the nuts when the framing gripped
between the washers can be rotated to give tilt adjustment, and the attachment
can be slid backwards or forwards along the whole length of the troughed bar to
effect longitudinal adjustment or the whole of the said movements can be effected at
the same time, and after the necessary adjustments have been made, the screwing
up of the nut or nuts clamps the gripping washers to the frame rods, forces inwards
the body gripping checks turns them upon their upper parts as fulcra and makes
their overhanging and inclined parts forcibly impinge against the sides of the bar
which are in turn closed upon the foot of the middle block, hence the affixing of
the attachment boss to the seat support, and the saddle to its connection.
I wish it to be understood that I do not limit myself to the described cross
section of the trough bar so long as the sides are undercut or arranged to overhang
the foot of the middle block.
Figure 1 of the accompanying drawings represents in side elevation, with the
saddle seat in section, a combined saddle support and securing attachment or boss
constructed arranged, fitted and working according to my invention.
the boss is shown at the extreme forward end of its support.
In this view
Figure 2 is a like view as Figure 1, but with the boss coming mid-way between
the two ends, showing how the boss can traverse from end to end of the same
uninterruptedly or without obstruction.
Figure 3 is a topside plan of Figure 2, but with the seat broken away.
Figure 4 is a vertical section of the attachment upon the dotted line c, Figure 2,
showing the relative positions of the assembled component parts of the combined
support and boss.
Figure 5 represents side and end elevations and a plan of the sliding block which
constitutes the body of the boss and whose foot is of the same cross section as the

page_text: inside of the troughed support, which is shown separately in side and end elevations.
and plan in Figure 6.
Figure 6 represents sections and elevations of the dis-assembled component
parts of the boss, including the central pin upon which the several loose fittings
are strung.
Figure 7 shows an end view, Figure 8 a side elevation and Figure 9 a topside
plan of the trough sectioned support or bar and seat support or pillar.
The same letters of reference indicate corresponding parts in the several figures.
of the drawings.
Surmounting the seat pillar a, is a horizontal and trough sectioned support bar
or bed a', having overhanging and yielding sides a², and within which a like section.
foot , of a sliding carrier block or body part b, of the boss longitudinally traverses
or slides uninterruptedly from end to end of the said troughed section support or
bar. The upper end of this said body part, which is of a breadth about equal to
that of the open top as of the trough, is transversely pierced with a square hole b²,.
wherethrough the square body c', of a central screw-ended pin c, passes, with the
ends c², overhanging the inclined sides of the said support or bed, and upon each of
which a gripping cheek d, an inside frame-wire gripping washer e, and an outside
frame-wire gripping washer f, are strung, and are brought together and against the
side of the solid body part b, by a screw nut g. Now the gripping cheeks d, have
inwardly projecting bearing ribs or lugs d', which impinge upon the opposite side
faces b, of the body part b, and inclined lower bearing surfaces d², which impinge
against the outside of the inclined or overhanging and yielding walls a², of the
support a', which parts a², are forced slightly inwards and against the inclined
sides 6, of the foot b', of the said body b, on the nuts g, on the ends of the pin c,
being screwed up.
These cheeks d have central square eyes d³, of a depth rather greater than that
of the pin, so as to admit of the same slightly rocking upon the lugs as centres in
order to allow the lower bearing surfaces d to follow up the slight change of angle
or plane which occurs in the overhanging sides a², when the same are pressed
inwards upon the foot of the block.
The outer faces of the gripping cheeks have rocking clearances d', and collars d³,
upon which latter the frame-gripping washers e, having holes el, through them and
keep grooves e, upon their outer faces for the reception of the frame wires h of
the saddle, take and are capable of rotation thereon. The inner faces of these
washers e, have hardened teeth e³, which embed themselves when forced home, into
the softer metal of the opposed faces of the gripping checks.
The outer frame washers f, which have holes fi, through their middles, have
keep grooves f, upon their inner faces for the reception of the frame wires h, and
take and rotate upon collars gl, of the nuts g.
When the parts of the boss and its support are assembled as in Figures 1, 2, 3
and 4 with one or both of the nuts g, slackened, the boss can be slid or made to
uninterruptedly traverse from end to end or to any part of the bed support a', and
any desired tilt can be given to the saddle i, carried by the frame rods h.
By now screwing up either one or other or both of the nuts g, the distance
between them is diminished and the whole of the assembled parts threaded upon
the pin are drawn together, with the frame rods h, firmly clamped between the
opposed faces of the pairs of washers e, and f, whilst the teeth of the washers e,
are embedded into the outer faces of the gripping cheeks d, which, in their turn,
are forciby impressed against the two opposite sides of the solid body part b, and
the inclined lower bearing surfaces against the outward presented faces of the
yielding sides a², of the bed rest a¹. By now further screwing up the nut or nuts,
the gripping cheeks are made to slightly turn inwards upon their lugs as centres
and so forcibly press inwards their lower parts, whereby the said sides are gathered
in and nipped between the lower surfaces of the gripping cheeks and the foot of
the block.
Figure 10 represents a modified form of my invention, in which the inner

page_text: rotating washers for effecting tilt adjustment are dispensed with, and cambered or
curved parts of the frame wires lying within like curved grooves in the opposed
faces of the outer washer and gripping cheek on each side of the boss are employed
in lieu thereof.
Figure 11 shows an elevation of the outer and grooved side of one of the gripping
cheeks and Figure 12 is a section of the same upon the dotted line 2.
Figure 13 is an elevation of the grooved side of one of the outer washers and
Figure 14 a vertical section thereof.
It is understood that when four-wire frames are employed, two corresponding
grooves are formed on the opposite sides of the holes in the opposed faces of the
outer washers and gripping cheek.
i is the saddle seat, and h the framing, having a curved or cambered middle
part 2, taking into and lying within the opposed and corresponding curved keep
grooves 3, d, of the outer washers f, and gripping cheeks d, carried by the boss
which slides within the trough bar or support surmounting the seat pillar a.
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 cycle saddle support and attachment boss, comprising a seat pillar
surmounted by a longitudinal bed or bar having inclined sides, upon which, opposed
and like inclined faces of gripping cheeks, whose upper portions bear against an
intervening block or support as a fulcrum, come and are there clamped by a
wedging action, on the said cheeks being forced home by the tightening up of the
said attachment through the medium of nuts or equivalents screwing upon a bolt
or other carrier.
Secondly. A support and attachment boss for cycle saddles consisting of a seat
pillar, surmounted by a trough-sectioned bed preferably having yielding sides and
fitted with an internal support in the form of a sliding block or body of the attach-
ment boss and with gripping cheeks or members strung upon a pin or equivalent
and taking a bearing upon the outer sides of the said bed, the said yielding sides
being thus nipped and clamped between the internal block or support and the outer
gripping cheeks or members, substantially as and for the purpose described and set
forth.
Thirdly. A support and attachment boss for cycle saddles consisting of a seat
pillar, surmounting by a trough sectioned bed, preferably having yielding sides
fitted with an internal support in the form of a sliding block or body of the attach-
ment boss, and with gripping cheeks or members strung upon a pin or equivalent
and taking a bearing upon the outer sides of the said bed, which are thus nipped
and clamped between the internal block or support and the outer gripping cheeks
or members and with a frame clamping washer or washers and a securing nut or
nuts also taking upon the ends of the pin or equivalent substantially as described
and set forth.
Dated this 4th day of February 1897.
