PROVISIONAL SPECIFICATION.
Improvements in Attachment Bosses for Cycle Saddles.
I, ALFRED JEROME BETTERIDGE, of 126, Fentham Road, Birchfields, near the
City of Birmingham, Foreman of Department, do hereby declare the nature of
this invention to be as follows; —
This invention has relation to the attachment bosses or clips of cycle saddles
and has for its object, to prevent the component parts of such bosses from moving
or turning upon one another after clamping. This I propose to accomplish by
the employment of an auxiliary device in the form of a friction cone, situated
upon the inner faces of the frame-clamping washers adapted to be fitted and
clamped within like coned seatings formed in the faces of the element or part
which clips the seat pillar.
•
In carrying out one form of my invention, I take a U-shaped clip or body
part adapted to embrace the seat pillar or support, with thoroughfare holes pass-
ing laterally through the cheeks or sides, the outer entrances of which holes are
plain-coned sunken, the coning of the said sinkings being only very slight.
These sinkings receive corresponding and plain he coned projections, rings or
collars formed on the inner or opposed faces of the innermost frame-gripping
washer, which have keep grooves on their outer faces to receive the framing
members, the latter being there retained by plain outer washers. The whole
of the several components parts are provided with coincident holes through
which the clamping pin passes and are clamped together by the screwing up of
nuts on the screwed ends of the pin and by the plain surfaced he-conings on the
washers being forced into corresponding plain she-conings in the cheeks of the
clip, the rotation of the one part upon the other is prevented.
propose that the plain conings of the socketting parts should be formed at
such an angle that when the nuts on the ends of the pin are slackened back, they
shall be self-releasing, or immediately admit of turning upon one another when
slight pressure is put upon the saddle.
Instead of the he-cones being formed upon the washers, they may be arranged
upon the outsides of the clip body to socket into plain-surfaced she-conings on
the inner sides of the washers, and, if necessary, the coned parts may be cross-
split at points to enhance the grip.
As a further form, the socket or she cone may be fitted with a loose split conical
lining or ring, which adapts itself to the he-coned part and by expanded therein
when the nuts are screwed up, it increases the frictional contact between the
socketting parts but automatically expands when the clamping nuts are screwed
back.

page_text: I, ALFRED JEROME BETTERIDGE, of 126, Fentham Road, Birchfields, near the
City of Birmingham, Foreman of Department, do hereby declare the nature of
my said invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
This invention has relation to the attachment bosses or clips of cycle saddles
and has for its object, to prevent the component parts of such bosses from moving
or turning upon one another after clamping. This I propose to accomplish by
the employment of an auxiliary device in the form of a friction cone, situated
upon the inner faces of the frame clamping washers or collars and adapted to
be fitted and clamped within like coned seatings formed in the faces of the
element or part which clips the seat pillar.
In carrying out one form of my invention, I take a U-shaped clip boss or body
part adapted to embrace the seat pillar or support, with throughfare holes pass-
ing laterally through the cheeks or sides, the outer entrances of which holes are
plain coned sunken the coning of the said sinkings being only very slight.
These sinkings receive corresponding and plain he coned projections, rings or
collars formed on the inner or opposed faces of the innermost frame gripping
washers or collars, which have keep grooves on their outer faces to receive the
framing members, the latter being there retained by plain outer washers. The
whole of the several component parts are provided with coincident holes through
which the clamping pin passes and are clamped together by the screwing up of
nuts on the screwed ends of the pin and by the plain surfaced he-conings on the
washers being forced into corresponding plain she-conings in the cheeks of the
clip or boss by which the rotation of the one part upon the other is prevented.
propose that the plain conings of the socketting parts should be formed at
such an angle that when the nuts on the ends of the pin are slackened back, they
shall be self releasing, or immediately admit of turning upon one another when
slight pressure is put upon the saddle.
Instead of the he-cones being formed upon the washers or collars they may be
arranged upon the outsides of the clip or boss body to socket into plain surfaced
she-conings on the inner sides of the washers, and, if necessary, the coned parts
may be cross split at points to enhance the grip.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a sheet of drawings upon which
I have given an example of a boss with the frame wires of the saddle attached
thereto, but it must be understood that other kinds of wires and other saddle
seats may be attached to the boss or collars C at the sides of the boss and be
similarly effective for the purpose of locking the saddle or seat at any desired
inclination. The great point of my invention is its exceeding simplicity and the
small number of parts used to serve the purpose effectively.
Figure 1 is a side elevation of the boss or clip and a portion of a saddle, wire
frame.
Figure 2 is a cross sectional elevation on the line 1-2 shewing the parts in
position as they would be when tightened upon an L or saddle bar.
Figure 3 is a side view of the boss or clip with the washer or collar C and
pin removed.
Figures 4 are back and side elevation of the collar or washer C.
The boss B is of the ordinary U type having a bolt or pin P passing through
the two legs of the U in such a manner that they can be tightened together upon

page_text: any L or saddle bar S. The collars or washers C which are provided with suit-
able grooves into which the wires W constituting the under frame of the
saddle take are similar to the ordinary collars with the exception that I provide
the inner face with a cone piece projection or recess c¹ which fits into correspond-
ing recesses 6' in the boss B. When therefore the boss B is tightened upon the
saddle bar S by screwing up the nut on the pin P the cones c¹ are pressed against
the sides b' of the tapered or coned recess in the sides of B and securely lock the
boss or clip into any desired position upon the saddle bar. When the inclina-
tion of the saddle is required to be altered it is only necessary to slacken the nut
when the alteration may be accurately made, when, the pin is tightened up again
and the saddle locked without any complicated parts. It will be clearly seen
that the conical recess may be in the nut and the projection on the sides of B but
I prefer the one as shewn. I am aware that cones have before been used in
conjunction with sliding or expanding pieces or split rings which is a complicated
and expensive arrangement and I therefore make no exclusive claim to the use
of cones.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is
CLAIM.
The improvement in attachment bosses or clips for cycle saddles, consisting
of conical recesses or projections in the sides of the boss or clip acting in com-
bination with corresponding projections or recesses in the collars or washers
fitting into the same substantially as and for the purpose herein set forth and
shewn upon the accompanying drawings.
