PROVISIONAL SPECIFICATION.
Improvements in or connected with Clips for Tubes and Bars,
specially applicable to Velocipedes.
We, SAMUEL TWEEDALE of Haugh Cycle Works, Oldham Road, Rochdale in
the County of Lancaster, Cycle Manufacturer and JAMES CLEGG of Walmsley
House, Manchester Road, Rochdale Commercial Traveller, do hereby declare the
nature of this invention to be as follows :-
This invention relates to clips for readily securing moveable parts to tubes and
bars and consists in an improved construction of clip and means by which it is
tightened upon the tubes or bar the object being chiefly to dispense with the use of
a separate spanuer or key and make it self-tightening.
In carrying out this invention we make the gripping part of the clip of usual
form, say, for a round cylindrical tube or bar a deep split ring or band having two
parallel lugs or ears formed thereon in such manner that when drawn together the
band is contracted. We bore a hole through the two lugs and pass a bolt there-
through having preferably a screwed end and fitted with a milled nut. The head
of the bolt secures a lever, the inside face of which or the opposing face of the lug
of the clip, is formed with an annular inclined or other projection or more than one.
Whichever face is formed with the projection or projections, the corresponding face
is formed with corresponding indentations so that when the projection or projections
on the one face coincide with the indentation or indentations in the opposing face
the clip is open or expanded. When the lever is turned on or with the bolt each
projection rises out of its corresponding indentation and the lugs of the clip
consequently move a corresponding amount of space equal to about the depth of
the indentations, towards each other. To prevent the lever from slipping back
again another slight indentation is formed in one face opposite one of the
projections, into which the latter slips when the lever is in the position of
"locked."
I may form the inclined projections by means of small balls as used for ball
bearings let into one of the parts and the indentations as cupped recesses in the
other part.
By means of the milled nut and screwel end of the bolt the clip may be nicely
adjusted first before being locked so that the best effect may be produced.
This improved clip is specially applicable to velocipedes and like machines when
it can be used to great advantage for locking the handle-bar stem to the steering
post and by opening out the underside of the clip may also clip and lock the
adjusting cone or ball-race of the steering post bearings. The clip is also
applicable to the seat-post for adjusting the vertical position of the seat or saddle
thereon. In the former case the free end of the locking lever may be formed into
the lamp carrier.

We, SAMUEL TWEEDALE of Haugh Cycle Works, Oldham Road, Rochdale in
the County of Lancaster, Cycle Manufacturer and JAMES CLEGG of Walmsley
House, Manchester Road, Rochdale in the County of Lancaster, Commercial
Traveller, 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 clips for readily securing moveable parts to tubes and
bars, and consists in an improved construction of clip and means by which it is
tightened upon a tube or bar, the object being chiefly to dispense with the use of
an independent spanner or key, and make the clip and tightening means self-
contained so that it may be quickly adjusted and removed.
The invention is specially applicable to velocipedes and like machines in which
it may be used to great advantage in the clip for locking the handle bar stem to
the steering post; in the seat post clip; in clips for readily attaching parts such as
lamp brackets, foot rests and parcel carriers; and it may be used with advantage
in other cases and for other purposes where it is required to readily lock and attach
parts to tubes and bars.
The improved clip consists of a split band or hoop capable of contraction by
means of a screwed bolt and a lever so formed that by a movement of the lever the
split band grips or releases the tube or bar upon which it is mounted; the lever
being either arranged to lie in the direction of the tube or bar, or formed and
arranged to act as a lamp holder or a foot rest or for other useful purposes.
In the drawings attached hereunto one method of forming according to our
invention a self contained clip and tightening means is illustrated and which is
intended also to act as a lamp bracket or carrier.
Fig. 1 represents a side view of the clip or device; Fig. 2 a plan ;
Fig. 3 a view of the inside face of the lever;
Fig. 4 a side view of the split band or gripping part.
The form of clip and tightening or locking means illustrated in these views is
intended rather to illustrate the manner of obtaining adjustment and locking or
tightening the clip and of obtaining the necessary leverage to cause the clip to grip
tightly the tube or bar than to illustrate any particular form.
fall out.
Referring to the several views, it will be seen that the gripping part of the clip a
consists of a split ring or band formed with lugs or cars at a² and of well known
form. The lug is pierced in the usual way for the reception of a bolt b which is
however made longer than usual. Upon the face of one of the lugs are formed,
preferably two inclined projections a³, a which may with advantage be hard metal
balls let into the face and secured thereto, preferably so that they may turn but not
We arrange upon the bolt 6 preferably next to the head of the bolt, a
lever or arm c. The face of this lever opposing that of the lug a' is formed with
indentations c c corresponding to the inclined projections or their equivalent on
the lug. These indentations are arranged according to the desired position of the
end of the lever relative to the bar or tube passing through the lug. In the case
of the lamp bracket formed by the lever as illustrated in the drawings, the relative
position of the lever with reference to its length, to that of the tube or bar or axis
of the band or clip is more or less angular owing to the steering part for which this
special clip is designed being vertical or inclined from the vertical. The face end c
of this lever c is formed to fit the socket of a lamp and may be of any convenient
shape. The bolt 6 is provided with a preferably milled nut 6¹ by which the limit of
contraction to be allowed the gripping part is regulated.

page_text: The number of the inclined projections and corresponding indentures may be
varied.
The adjustment of the clip which is generally made a shade larger than the bar
or tube, to the said tube or bar is first obtained by this nut b', while the inclined
projections as and a lie in the indentations in the face of the lever c, due allowance
being made for the amount of contraction which is produced in the band or clip
when the lever is moved and the projections rise, relatively speaking, out of the
indentations.
The lever is preferably arranged to turn loosely upon the bolt b and it is
advantageous to prevent the bolt from turning in the lugs or with the lever.
The converse of the arrangement of inclined projections and indentations in the
respective faces of the lug and lever may be employed; that is the projections may
be formed on the face of the lever and the indentations formed in the face of the
lug or gripping part. The projections and corresponding indentations may be of
any suitable form, that form, however, shewn in the drawings being convenient and
inexpensive to make.
In order to retain the lever or arm in the position in which the clip is fixed so
that it shall not readily move without pressure being applied to the end of the arm
or lever we may form another but much shallower indentation in the face
opposite that formed with the projections, in such a position that when the band or
clip is fixed or contracted one of the projections engages in the shallow indentation
and thereby prevents the lever from turning by vibration and so loosening the clip.
Two or more of these shallow indentations or the equivalent thereof may be
formed.
It is obvious that a band or clip with bolt and tightening lever constructed and
arranged in the manner described and illustrated may be used for many purposes
where the clip is required to be quickly and easily applied and removed, and where
the lever or arm may be useful for another purpose.
In some cases we may dispense with the adjustment provided by the uut 6' and
screwed end of the bolt and secure a nut or hoop or their equivalent in a fixed
position on the bolt, or we may tap one of the lugs and screw a screw formed with
a head into it. In some cases we may form the recesses in the head of the bolt and
projections on the side of the lever next to it, or vice versa the bolt being in this
case prevented from turning by any suitable means ordinarily used for this
purpose.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. The manufacture and use of clip for tubes and bars made substantially as and
for the purpose described hereinbefore.
2. In clips for gripping tubes and bars the manner of contracting the gripping
part by means of a lever and an inclined projection or more than one in combina-
tion with a bolt or screw substantially as and for the purpose herein before
described.
3. In combination with a band clip having lugs formed thereon and a screw bolt
passed through the lugs of a lever and inclined projections and indentations formed
respectively upon the opposing faces of the lugs and lever substantially as described
and for the purpose set forth.
4. The adjustable combined clip and lamp bracket substantially as described and
illustrated in the drawings and for the purpose set forth.
