I, HARRY CLARK, of 3, High Street, Littlehampton, in the County of Sussex,
Ironmonger, do hereby declare the nature of this invention to be as follows:-
The object of my invention is so to construct and fit sleeves and such like
appliances and to provide for the same such devices that they can very quickly and
easily be very tightly clamped in their desired positions on the bars posts and other
articles whereon they are to be used and this arrangement will be very especially
applicable in and for velocipedes in respect of seat pillars steering posts and the like.
To carry out this object the sleeve is a split sleeve or a part thereof only may.
be split in which case the split part is partially divided from the whole part by
transverse cuts and on the split sleeve or part of a sleeve are formed two projecting,
lugs or flanges facing each other as is usual through which lugs or flanges are made
corresponding holes. A bolt or pin is made which can pass loosely through these
holes and on the two ends of this bolt are created right and left handed screw.
threads and two rings or annular discs are provided having complementary female.
screw threads which can be screwed on the inale right and left handed screw threads -
on the bolt. The bolt is passed through the holes in the lugs and on one end of the
bolt is screwed the corresponding ring which has on its inner face a stud or the like
which can be engaged in a recess or slot made therefor in the outer side of this lug.
so that this ring cannot be revolved and then the other ring is screwed on the other
end of the bolt until it is against the outer side of the other lug. This end of the
bolt is so formed in any ordinary manner that this bolt can be revolved as for.
example by a butterfly nut or a wrench or a detachable handle or a pin passing
through it or a lever arm fixed to it or in any other convenient manner but it is.
obvious that when this bolt is so revolved in the proper direction the effect of the right.

Improvements in Clamping Sleeves and the like round Bars,
Posts, and other Articles, more especially applicable in and
for Velocipedes.
I, HARRY CLARK, of 3, High Street, Littlehampton, in the County of Sussex,
Ironmonger, 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 :-
The object of this my invention is so to construct and fit sleeves and suchlike
appliances and to provide for the same such devices that they can very quickly and
easily be exceedingly tightly clamped in their desired positions on and round the
bars posts and other articles whereon they are to be used and this apparatus and
arrangement will be more especially applicable in and for velocipedes in respect of
seat pillars steering posts and the like.
In order the more clearly to explain this my invention and in what manner the
same is to be performed I refer to the accompanying drawing wherein I have shewn
the same as applied to and with the seat pillar of a safety bicycle and Figure 1 is a
perspective elevation of that part of the frame of a safety bicycle that is near and
about the upper part of the seat pillar Figure 2 is a very convenient form and style
of the clamping bolt that I use and Figure 3 is the upper end of one of the rear
members of the frame.
The ordinary sleeve A that is secured to the top of the seat pillar B and to the
rear end of the top member D of the frame is a split sleeve being divided on its rear
side as shown at E and near this split or division E on both sides thereof are formed
two projecting lugs or flanges F facing each other through which lugs F are made
corresponding boles as is generally customary in this part of the frame of a safety
bicycle. A bolt or pin H is made which can pass loosely through the holes in the
lugs Fand on the two ends of this bolt H are created respectively male right and
left handed screw threads K. Two rings or annular dises 1. are made being provided
with complementary female right and left handed screw threads which rings L can
bé screwed respectively on the male right and left handed screw threads K and on
the inner face or side of one of the rings L is created a stud M or the like which
stud M can be engaged in a corresponding recess or slot N made therefor in the
outer side or face of the end of the rear member P of the frame when my invention.
is applied and used as is shewn in the drawing or in the outer side or face of the
lug F when my invention is otherwise applied and used so that in either case this
ring L cannot be revolved when the stud M is engaged in the recess N. It is also
very convenient in a great many cases to create the stud M in a complementary
manner on the other ring L¹ also and the recess N in the other rear member P or in
the other lug Falso by which arrangement when it is possible and expedient so to do
the action of the bolt H will be rendered far more speedy effectual and rapid. One
end of the bolt H is so formed and fitted in any ordinary manner that such bolt H
is capable of being revolved by any ordinary appliance or device such for example as
a butterfly nut or a wrench or a detachable handle or a fixed lever arm or the like
and I shew in the drawing one very convenient form and style of construction for
effecting this purpose. On, and it may preferably be with the one end of the
bolt His created a square head R wherethrough may also be made a small
transverse hole T by which arrangement the bolt H can obviously be revolved either
by a spanner or the like on or round such head R or by a lever pin through
such hole T.
The action and method of using this apparatus when the same is made and fitted
and arranged as is hereinbefore described and as is shewn in the drawing are as
follows.

page_text: That ring L that is to be the nearer to the head R is first passed on the bolt H
and is screwed up against such head R and to render this operation the easier and
quicker in performance it is most convenient to make the bolt H of a larger diameter
near its head R than at its other end whereby also the male screw thread K¹ thereon
near the head R will likewise be of a larger diameter than the male screw thread K
thereon at the other end as is shewn in Figure 2 and therefore the ring L' which
can be screwed on the male screw thread K³ will be capable of being passed over the
smaller end of the bolt H without engaging the male screw thread K thereon. The
bolt H is then passed first through the usual hole in the end of one of the rear
members P and then through the hole in one of the lugs F thence through the hole
in the other lug F and finally through the usual hole in the end of the other rear
member P. The other ring L is then screwed on the end of the bolt H until its
stud M is engaged in the corresponding recess N in the rear member P when the
ring L is screwed back again if advisable or necessary against the other rear
member P and if so made and fitted until its stud M likewise is engaged in the
corresponding recess N in such other rear member P. The bolt H is then duly
revolved in the proper direction and it is obvious that the effect of the right and left
handed screw threads K on the rings L one of which rings L is non-revoluble will
and must be to draw these rings L closer together and therefore also the lugs F on
the sleeve whereby this sleeve A will quickly and easily be exceedingly tightly
clamped on and round the saddle pillar V as is desired while if and when the other
ring L also is non-revoluble such operation will obviously be rendered far more
speedy effectual and rapid and this is very convenient.
In a similar manner as is very evident this my invention can be applied to and
with and in all other positions and places and apparatus wheresoever it is desired to
clamp a sleeve or the like round and on a bar or post or other article whether in or
on velocipedes or elsewhere and no further description or explanation is or can be
needed.
When it is not desired to split the whole sleeve a part thereof only may be split
as is customary and this split part is separated in the ordinary manner from the
other part by circumferential cuts made as lengthy as may be desired which split part
is fitted and treated as is herein before described and can be clamped in the same
manner.
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:
1. The combination with a split sleeve A provided with two lugs F of a bolt H to
pass through such lugs F male right and left handed screw threads K on the ends of
such bolt H rings 1 to be screwed on such threads K with a stud M on one or on
each of such rings L to be engaged in a recess N and thereby be made non-revoluble
and means for revolving the bolt H substantially as and for the purpose hereinbefore
described and declared.
2. The improvements in clamping sleeves and the like round bars posts and other
articles substantially as hereinbefore described and shewn in the accompanying
drawing.
