PROVISIONAL SPECIFICATION.
Improvements in and relating to Velocipedes.
I, CHARLES ANDREW EDWARD TALBOT PALMER, of "Gairlochy" Handsworth Wood,
Birmingham, in the County of Warwickshire, Manager of Works, do hereby declare
the nature of this invention to be as follows:-
My invention relates to an improved clip for holding the adjustable parts of cycles
such as the seat and handle bar pillars; and it has for its objects, the better
and safer locking together of the respective parts, and the interchangeability
thereof.
It is usual in these parts (which are made of weldless steel tube) to make the one
part slide within the other, contracting the outer part by a split collar or its equivalent,
to grip the inner part. As these parts often engage with one another for a
considerable distance there is great friction between the parts entailing considerable
force to move the one with respect to the other, and in these tubes although the
exterior guage is approximately accurate the interior guage is not sufficiently so
to enable the two parts to be made interchangeable.
By my improvements these objections are overcome. I take a piece of weldless or
other tube and fit on to the top of it a split collar or its equivalent. 'This collar is
recessed about half way through to receive the tube and the diameter of that part
through which the tube does not pass is made of a diameter slightly less than the
internal diameter of the tube. The adjustable tube carrying the handle bar or saddle
is made to fit this part of the split collar so that it does not bear on the inner side
of the fixed tube, thus avoiding the objections herein before set forth. The split collar
or its equivalent may be of any suitable exterior shape and may be fixed to the tube
by screws or by brazing. For diamond shaped frames I utilize the split socket to
form or carry snugs to receive the members of the said frame, which are preferably
affixed thereto by nuts adapted to screw on to stud pins formed on the said snugs.

COMPLETE SPECIFICATION.
Improvements in and relating to Velocipedes.
I, CHARLES ANDREW EDWARD TALBOT PALMER of "Gairlochy" Handsworth Wood,
Birmingham in the County of Warwickshire, Manager of Works 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 :-
-
My invention relates to an improved clip for holding the adjustable parts of
cycles such as the seat and handle bar pillars, and it has for its objects, the better
and safer locking together of the respective parts and the interchangeability
thereof.
It is usual in these parts which are made of weldless steel tube to make the
one part slide within the other, contracting the outer part by a split collar or its
equivalent to grip the inner part. As these parts often engage with one another
for a considerable distance, there is great friction between the parts entailing
considerable force to remove the one with respect to the other for adjustment and in
these tubes, although the exterior guage is approximately accurate, the interior
guage is not sufficiently so to enable the two parts to be made interchangeable.

page_text: By my invention these objections are overcome. I fit on to the top of the tube
adapted to receive the adjustable part a split collar or its equivalent. This collar is
recessed about half way through to receive the tube and the diameter of that part
through which the tube does not pass is made of a diameter slightly less than the
internal diameter of the tube. The adjustable tube forming the seat or handle bar
pillar is made to fit this part of the split collar so that it does not bear on the inner
surface of the fixed tube, thus avoiding the objections hereinbefore set forth. This
split collar or its equivalent may be of any suitable exterior shape and may be fixed
to the tube by screws, soldering or brazing preferably by screws. For diamond or
semi-diamond shaped frames I utilize the split socket to carry snugs or studs to
receive the top back members of the said frame.
In order that my invention may be fully understood I will more particularly
describe it making reference to the accompaning drawing in which Figures 1, 2, & 3 are
views in sectional elevation, elevation, and plan, respectively of one form my improved
clip may assume, and Figure 4 is a modification thereof. Throughout these views
similar parts are marked with like letters of reference.
A designates the improved clip, the eye of which is made of two different diameters
each extending approximately halfway through the eye of the clip. The diameter of
the bottom half of the eye of the clip is such as will allow it to receive the end of
the tube X forming part of the frame of the machine to which it is attached either
by one or more screws ✗ or by sweating or brazing. The diameter of the top part
of the eye of the clip A is slightly less than the internal diameter of the tube X and
is adapted to allow the tube Y forming the seat or handle bar pillar to slide freely
through it, the external diameter of the tube Y obviously being slightly less than the
diameter of the tube X. The clip A is split vertically and is provided with two lugs
a. a through one of which a set screw B passes and is threaded into the other, thus
providing a means of contracting the internal diameter of the clip to grip the tube Y.
The snugs a. a are preferably placed as near to the top of the clip A as possible and
the tube X is split vertically for a short distance to allow the clip A to be contracted
by the set screw B.
When the clip is intended for the seat pillar of diamond or semi-diamond shaped
frames it is provided with snugs or studs C. C.-as shown in dotted lines in Figure 3
of the accompaning drawing adapting it to receive the members of the top back-
fork of the said frame. It may also be provided with a snug D to carry the mudguard
as shown by Figure 3.
Instead of placing the clip A outside the tube X it may be placed inside as shown
by Figure 4 with equal effect, the outside of the clip in this case being made of two
different diameters instead of the inside.
It will be seen that with this improved clip the adjustable tube is gripped directly
by the clip and not by the fixed tube through the clip, thus allowing the external
diameter of the adjustable tube to be so much less than the internal diameter of
the fixed tube that there will be no friction between the two tubes during
adjustment.
It will be obvious that the clip may be made of any desired size and may be
adapted to receive a solid seat or handle bar pillar instead of a tubular one if
desired.
Having now particularly described and ascertained the nature of my said
invention, 1 declare that what 1 claim is :-
:-
1. The improved method of locking the adjustable parts of a velocipede to the frame
thereof as set forth.
2. A clip for fixing the adjustable parts of velocipedes to the non-adjustable parts
or frame thereof, consisting of a split band A having snugs a a adapted to receive a
setscrew B by which the internal diameter of the band forming the eye of the clip
may be contracted and having its interior diameter for one half its depth greater than
that of the other half of its depth, the half of the greater diameter being adapted to
receive the tube of the frame to which it is fixed by any suitable means, and the half

page_text: of the lesser diameter being adapted to receive the adjustable part the exterior
diameter of which is less than the interior diameter of the tube of the frame,
thereby allowing the clip to grip the adjustable tube or part directly and not
through the fixed tube as and for the purpose set forth.
3. In a split clip for fixing the adjustable parts of velocipedés to the frame
thereof, making the eye of two different diameters the one to receive the tube of
the frame, and the other the adjustable tube or part, so that when the clip is
contracted it may grip the adjustable tube or part directly, as and for the purpose
set forth.
4. A split clip for fixing the adjustable parts-such as the seat pillar and handle
bar pillar to the frame of a velocipede, adapted to be fixed on or in the tube of
the frame in such a manner that the adjustable part is free to pass through the clip
and be gripped by it without touching the tube of the frame as set forth.
5. The combination with the split clip of a velocipede adapted to be fixed in or on
the tube of the frame and receive and grip the seat pillar directly without the
intervention of the tube of the frame, of the snugs or studs C. C as and for the
purpose set forth.
