Improvements in Cycle Saddle Attachment Clips.
I, ROBERT OSBORNE COWAN, of "Rednall," Bristol Road, Bournbrook, near the
City of Birmingham, Works Secretary, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to cycle saddle securing bosses or attachment clips, and
has for its object, a simple and efficient method of attaching or securing the saddle
framing to the boss or clip, and the clip to the seat pillar or pin of a bicycle.
The improved boss comprises a clipping ring or eye for taking upon the L-pin
or seat pillar, having opposite screwed stalks or trunnion ends with the walls of the
ring partly split or divided from the inner circumference thereof outwardly into
the middle of the shanks of the stalks or trúnnion ends which shanks are conoidally
shouldered at the points of their junction with the ring, with the inclines thereof
tapering downwards from the ring to the screwed ends.
Fitting upon the said conoidal shoulders are contracting or gathering in washers
or collars, with the holes or eyes in their middles also conoidally formed, but with
their largest parts being less in diameter than the cones of the shoulders, but when
the said washers are forced home or inwards, they draw together the slits and close
the ring circumferentially around the L pin or pillar member.
In addition to the aforesaid gathering in collars I employ also outside washers
strung upon the pins and with keep grooves upon their inner sides for receiving
the frame rods which come and are clamped between the opposed faces of the inner
collars and outer washers, while screw nuts take upon the ends of the stalks of the
ring and which when wrung up, gather in the ring and secure the boss to the seat
pillar or pin, and at the same time force inwards the outer washers and thus, by the
same operation, clamp the frame wires between said washers and the inner collars.
The washers carrying the frame wires admit of turning about the trunnion ends
as centres when the tilt of the saddle requires to be adjusted, and after the parts of
the attachment have been loosened, the horizontal adjustment of the framing
wires through the boss is admissible.
"
The ring may be made from a length of half-round sectioned, wire bent up into
the form of a bolt with a gripping ring in its middle.
It is obvious that the inner washer of each pair need not revolve but may remain
stationary upon a square-sectioned shank of the ring, and thereby act only as an
abutment for the wires of the saddle frame, which lie in keep grooves in the inner
faces of the outer washers.
It is understood that the inner washers, which are not frame holding washers,
serve the two fold purpose of forming an abutment for the frame wires and closing
together the walls of the clip.
Instead of employing a pair of washers, I may use a pierced U-shaped clip strung
upon the pin upon each side of the boss in lieu thereof, with keep grooves formed in
the opposed inside faces of the same for the purpose of receiving the saddle frame
wires.

itself, or it may be made from a nearly split piece of metal, first drilled to form the

Improvements in Cycle Saddle Attachment Clips.
I, ROBERT OSBORNE COWAN, of "Rednall," Bristol Road, Bournbrook, near the
City of Birmingham, Works Secretary, do hereby declare the nature of this inven-
tion 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 saddle securing bosses or attachment clips, and has
for its object, a simple and efficient method of attaching or securing the saddle
framing to the boss or clip, and the clip to the seat pillar or pin of a bicycle.
Figure 1 of the accompanying drawings represents the framing of a cycle saddle
fitted with an attachment boss constructed according to my invention.
Figure 2 represents upon an enlarged scale, a transverse vertical section of the
said boss, and Figure 3 represents the component parts of the same dis-assembled
or separately.
Figures 4 and 5 represents respectively elevations of the inner and outer side of
the inside washer, one of each of which is disposed on either side of the boss.
Figure 6 is a vertical section of the body part of the boss, upon the dotted
line, Figure 3.
Figure 7 is an end elevation of the same and Figure 8 another sectional view,
but taken upon the dotted line 2, Figure 6.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
The improved boss a, comprises a clipping ring or eye b, for taking upon the
L-pin or seat pillar c, having opposite screwed stalks or trunnion ends b¹, whilst
the walls of the ring are partly split or divided at 62, from the inner circumference
thereof outwardly into the middle of the shanks 63, of the stalks or trunnion ends
which shanks are conoidally formed or taper shouldered at the points of their
junction with the ring, with the inclines thereof tapering downwards from the
ring to the screwed ends.
Fitting upon the said conoidal shanks are contracting or gathering in washers
or collars d, with the holes or eyes d¹, in their middles also conoidally formed, but
with their largest parts d², rather less in diameter than the widest parts of the
coned shoulders so that when the said washers are forced home or inwards, they
draw together the splits 63, and close the ring b, circumferentially around the L-pin
or pillar member, which is gripped and firmly held thereby.
In addition to the aforesaid gathering in collars I employ also outside washers e,
strung upon the pins and provided with keep grooves e¹, upon their inner sides for
receiving the saddle framing rods 9, which come and are clamped between the
opposed faces of the inner collars which are also preferably coincidently grooved
at d³, and outer washers, while screw nuts h, take upon the ends of the stalks
of the ring, by the screwing up of which the inner collars are forced inwards, the
splits are closed and the gripping ring is contracted or gathered in to secure the
boss to the seat pillar or pin, and at the same time force inwards the outer washers
against the inner collars, thus, by the same operation, clamping the frame wires
between said washers and the inner collars,

page_text: The washers carrying the frame wires admit of turning about the trunnion ends
as centres when the tilt of the saddle requires to be adjusted, and after the parts
of the attachment have been loosened, the horizontal adjustment of the framing
wires through the boss, or of the boss along the wires, is admissible.
The ring may be made from a length of half-round sectioned wire bent up
the form of a bolt with a gripping ring in its middle.
into
It is obvious that the inner washer of each pair need not revolve but may remain
stationary upon a square-sectioned shank of the ring, and thereby act only as an
abutment for the wires of the saddle frame, which lie in keep grooves in the inner
faces of the outer washers, in which case, the said inner washers would serve the
two fold purpose of forming an abutment for the frame wires and closing together
the walls of the clip.
Instead of employing a pair of washers, I may use a pierced U-shaped clip strung
upon the pin upon each side of the boss in lieu thereof. Such a frame wire clip is
represented in Figure 9, and has opposite grooves g', formed in the opposed inside
faces g², of the halves of the same for the purpose of receiving the saddle frame
wires.
This U-shaped frame-wire clip may be made from a flat piece of metal folded
nearly upon itself, or it may be made from a nearly split piece of metal, first drilled
to form the keep grooves, slightly opened out, and then hardened so that the same
will spring outwards after being closed together.
Figure 10 represents a further modification of my invention, in which the outer
washers are dispensed with, whilst the keep grooves d³, in the clip closing collars d,
are sufficiently deep to receive the framing wires g, entirely, and to be there
retained by collars or shoulders f, of the tightening up nuts f, which are screwed
upon the wormed ends of the trunnions 6¹, of the ring b, outwards of the coned
shanks.
Instead of contracting the pillar clipping ring through the medium of frame
gripping washers as described, independent means for effecting this contraction,
such as a collar or nut screwing upon the shanks of the said ring, may be employed.
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: A cycle saddle attachment boss, having a split contracting ring or eye
adapted to be gathered or drawn around the saddle supporting member, by washer,
collars or equivalents being forced over conoidal shoulders or parts surrounding
the split parts.
Secondly: A cycle saddle attachment boss, comprising a pillar-clipping ring
or eye having opposite screwed stalks or trunnion ends, and with the walls of the
ring split or divided from its inner circumference outwardly into the shanks of the
said stalks, which are conoidally formed at their junctions with the ring and over
which washers, collars or equivalent means, are forced having preferably flared
eyes or holes, thereby closing together the splits and contracting the rings, sub-
stantially as described and set forth.
Thirdly: The general construction, arrangement and combination of the parts
of cycle saddle attachment clips, substantially as described and set forth.
