as to be
The improved construction consists of a spring band or horse shoe shaped
clip with the terminal ends formed into cheeks or enlargements, having thorough-
fare holes in their middles through which a single drawing up cross pin is
directed. Each of the outer sides of the cheeks has three equi-distant swells,
convexities or protuberances separated from one another by corresponding or
like shaped declivities or concavities, whilst threaded upon the same cross pin
and coming within the under boundary lines of the framing are single discs
or plates having holes through their middles and with their inner faces made
the exact counterpart of the opposite faces of the clip cheeks, but with the rises
or convexities of the one surface taking into the depressions or concavities of
the other, alike unto the meshing together of the teeth of a driving clutch,
whilst the outer sides have separated and curved frame-wire races or grooves,
wherein the wires constituting the sides of the saddle frame take, thereby pre-
venting the said discs from rotating, and in order to admit of the saddle being
tilted, the middles of the framing wires are curved to correspond to the curvature
of the wire-races in the liscs, so that whilst the said discs are held stationary
to the boss by the cross pin, the wires admit of making a slight sliding move-
ment so as to change the inclination of the plane of the seat.
The cross pin or bolt may have a large head at one end and a nut at the other,
intervening rings or discs being located between the inner faces of the head and
nut, or of two end nuts and the outer faces of the wires of the framing, which
wires are preferably made of a square section.
When the cross pin or bolt is tightened up after the adjustment of clip has
been effected the framing wires are rigidly connected to the side discs, which, in
turn, are made fast to the clip and the clip is drawn closely around its supporting
member.
Assuming that the boss has been applied to an L-pin, then in order to con-
vert it to a position suitable for taking upon the summit of a direct seat pillar,
simply loosen the bolt so as to admit of an amount of longitudinal play between
the opposed faces of the discs and clip cheeks, equal to the distance between the
top of one of the swells and the bottom of one of the declivities, so that when
the clip is to be turned to the proper angle, it is simply rotated and the swells
on its face are made to ride cam-wise up the inclines of the swells on the opposed
faces of the fixed discs and so forces outwardly and laterally the sides of the frame
and on the apices or summits of the swells have passed each other, then the

page_text: spring sides of the frame close together or return to the normal positions and
automatically take the swells of the opposed faces into the next adjacent de-
clivities, when the running up of the nut or nuts and the tightening of the bolt
makes fast the whole of the component parts.
Instead of employing swells or protuberances with double inclines on the
opposed faces of both discs and clip cheeks, such bosses may be formed on only
the one part and the other part may have teeth, pegs or equivalent projections
and instead of the discs having the framing wire races formed on its outer
faces, said races may be formed in separate discs or independent means may be
provided for effecting the tilting adjustments.
The shank end of the pin may be facetted to receive and prevent rotation of
the discs whilst the middle part of its stem may be round or of such a section
as will admit of the spring clip of the boss being turned thereon.

We, WALTER BRAMPTON, Manager of Brampton Brothers Limited, of Oliver
Street, in the City of Birmingham, and ALFRED JEROME BETTERIDGE, of 51,
Lozells Street, Aston, near Birmingham aforesaid, Foreman of Department,
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 attachment or securing bosses of cycle saddles,
of the interchangeable or universally adjustable type, which are applicable for
use in connection with either an L-shaped saddle pillar or a direct saddle pillar,
as may be required, and the object of the said invention is to provide such bosses
with simple means for determining and holding in their required positions,
the parts of the boss, which admits of being indifferently used in a number of
determinate positions, that is, with the band clip part in position to receive
the horizontal member of an L pin either above or below, whereby the height
of the saddle can be varied without moving the seat pillar, or to take upon the
summit of a direct pillar, either rearwards or forwards thereof.
Figure 1 of the accompanying drawing represents a front elevation of an
interchangeable cycle saddle attachment boss or clip constructed according to
our invention.
Figure. 2 is a right-hand side elevation of the said attachment boss, and
Figure 3 is an elevation of the left-hand side thereof.
Figure 4 is a transverse vertical section of the said boss, upon the dotted
line, Figure 2.
Figure is a like section of the boss as shown in Figure 4, but with the
several component parts only loosely assembled together, or in the positions
which they assume on the slacking back of the nut on the end of the clamping
pin. The band clip of the boss is shown in a different position to that repre-
sented in the preceding views, whilst Figure 6 is an elevation showing the band
clip in a further position, suitable for taking upon the summit of a direct seat
pillar.

page_text: Figures 7, 8, 9, 10, 11, 12 and 13 represent different views of the several com-
ponent parts of the boss.
The same letters of reference indicate corresponding parts in the said figures.
of the drawing.
con-
The improved attachment boss consists of a spring band or horse-shoe shaped
clip a, (see Figure 7) adapted to embrace the saddle pillar of a bicycle with the
terminal ends a', formed into cheeks or enlargements a², having thoroughfare
holes a³, in their middles through which a single drawing up cross pin b, (shown
separately in Figure 13) is directed. Each of the outer sides a, of the cheeks
has an undulatory surface or is provided or formed with a series of equi-distant
and radially disposed swells, convexities or protuberances a³, separated from
one another by corresponding or like shaped intervening declivities or
cavities a, whilst threaded upon the same cross pin and coming within the
inside of the framing members c, of a cycle saddle are a pair of single non-
rotating discs or plates e e¹, (see Figures 8 and 9) each having a hole e³, through
its middle and with the inner face e, being provided with alternating rises and
declivities e, e, which are the exact counterpart of the opposed face a, of the
clip cheek a², but with the rises or convexities of the one surface taking into
the depressions or concavities of the other, alike unto the meshing together
of the teeth of a driving clutch, or, in other words, the raised portions of the
one undulatory surface correspond to and take into the opposite sunken portions
of the other surface. The outer sides e6, of these cheeks have separated and
curved frame-wire races or grooves e', wherein the wires c, constituting the sides
of the saddle frame and which are preferably of a square or angular section,
take and thereby prevent the said discs from rotating relative to the framing,
and in order to admit of the saddle being tilted, the middles of the framing wires
are curved (see Figures 2, 3 and 6) to correspond to the curvature of the wire-races
in the discs, so that whilst the said discs are held stationary to the boss by the
cross pin, the wires may be caused to make a slight sliding movement within
the said curved races so as to change the inclination of the plane of the seat.
The cross pin or bolt b, may have a large head b¹, at one end and a nut d,
may take upon the other and screwed end 62, intervening clamping rings or
discs f, (see Figures 10 and 11) being located between the inner faces of the
head and nut (or between two nuts screwed onto the wormed ends) and the outer
sides of the wires of the framing. The said pin is prevented from rotating,
when the nut is screwed up by the frame wires bearing upon the flats 63, bs,
on the opposite sides thereof.
When the cross pin or holt is tightened up after the adjustment of clip has
been effected the framing wires are rigidly connected to the side discs, which, in
turn, are made fast with the clip, with their respective undulatory or clutch-
like surfaces engaging with one another, (see Figures 1 and 4) and the clip is
drawn closely around the saddle pillar of the bicycle.
Assuming that the boss is in a position suitable for taking onto the horizontal
member of an L-shaped saddle pillar and that it is required to convert it to a
position suitable for taking upon the summit of a direct seat pillar, simply
loosen the bolt to such an extent that will admit of an amount of longitudinal
play between the opposed faces of the discs and clip cheeks, so that when the
clip is to be turned to the proper angle, it is simply rotated and the swells on
the outer faces of its cheeks are made to ride cam-wise up the inclines of the swells
on the opposed faces of the fixed discs and so force outwardly and laterally the
sides of the frame and when the apices or summits of the swells have wiped past
or over each other, then the spring sides of the frame close together or return
to their normal positions and automatically take the swells of the opposed faces
into the next adjacent declivities, when the running up of the nut or nuts and
the tightening of the bolt makes fast the whole of the component parts.
It is understood that in addition to the opposed undulatory or double inclined
clutch-like formations serving as a means for retaining the clip in its determinate

page_text: position relative to the fixed frame discs, they also facilitate the operation of
finding or determining the positions in which the said clip is to be placed.
Figure 14 represents a front elevation and Figure 15 a side elevation of a
saddle attachment boss constructed according to our invention and adapted for
use in connection with a single wire saddle framing. The only difference
between this boss and that hereinbefore described and represented in Figures 1
to 12 is that the outer faces of the discs are each provided with a single frame
race instead of a pair as in the preceding arrangement. The said Figures 14
and 15 are marked with the same letters of reference as Figures 1 to 12.
Instead of employing swells or protuberances with double inclines
opposed faces of both discs and clip cheeks, such bosses may be formed on only
the one part and the other part may have teeth, pegs, or equivalent projections.
The shank end of the pin may be facetted to take through correspondingly
formed holes in the threaded-on discs whose rotation is thereby prevented whilst
the middle part of its stem may be round or of such a section as will admit of the
spring clip of the boss being turned thereon.
on the
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
First-In interchangeable cycle saddle attachment bosses, providing or
forming upon the opposed faces or surfaces of the moveable band clip and the
frame-carrying discs, undulatory or clutch-like engaging formations, acting in
the way and for the purpose herein set forth.
Secondly-An interchangeable cycle saddle attachment boss, consisting of
a saddle pillar clip, having free ends the cheeks of which are provided with
undulatory formations, opposed to non-rotating discs, the inner faces of which
have corresponding formations engaging with the undulations of the clip cheeks,
whilst the outer faces are provided with races to receive the saddle framing wires,
the whole being drawn together by a bolt or pin, substantially as and for the
purpose herein described and set forth.
