PROVISIONAL SPECIFICATION.
Improvements in the Construction of Crown Clips for Cycles.
GEORGE WILLIAM HAWKER 48 Spencer Street Birmingham Engineer do
hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the construction of crown clips for
cycles (crown clips are articles which are fixed in the crown of the front fork of
bicycles for the purpose of acting as a guide for brake plunger stem, & supporting
top part of mud guard of front wheel)."
The object of my invention is, to construct a crown clip whereby it may be
easily detachable to a cycle, & I accomplish that end by making my clip in two
halves & clamping it together by two screws in such a manner that it holds the
clip rigidly fixed to the crown, leaving a hole formed at the front for the brake
plunger stem & a smaller hole at the rear for screw which is used for attaching
mud guard.
The construction of my clip is as follows, I take two pieces of steel or any other
metal about " wide x " thick (although I do not bind myself to these dimensions)
& shape each piece flatwise into three half circles, leaving a flat space between
the two end half circles, & the centre half circles, through which said flat space
I pierce two holes, in the one piece of metal so formed, & tap two screwed holes
in the other piece of metal, to receive the two screws which are to clamp the clip
together, the three half circles in each piece of metal then form three complete
circles or holes. The centre hole is to fit the crown the hole at the front end is
for the brake plunger stem, & the hole at the rear end is for attaching mudguard.

Improvements in the Construction of Crown Clips for Cycles.
I, GEORGE WILLIAM HAWKER, of 48, Spencer Strect, Birmingham, in the
County of Warwick, Engineer, do hereby declare the nature of my said 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 improvements in the construction of crown clips for
cycles (crown clips are articles which are fixed in the crown of the front fork of
bicycles for the purpose of acting as a guide for brake plunger stem, and supporting
top part of mud guard of front wheel).
The object of my invention is to construct a crown clip whereby it may be
easily detachable to a cycle. I accomplish that end by making my clip in two
halves and clamping it together by two screws in such a manner that it holds the
clip rigidly fixed to the crown, leaving a hole formed at the front for the brake
plunger stem and a smaller hole at the rear for screw which is used for attaching
mud-guard.

page_text: In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto a double sized sheet of drawings, upon
which I have illustrated examples of my improved crown clip.
Figure 1 shows a piece of flat metal from which one half of my clip is
formed.
Figure 2 shows two of the strips of metal bent into the required shape placed
edgewise.
Figure 3 shows the two strips secured together by screws.
Figure 4 is an elevation of Figure 3.
Figure 5 is an elevation of a cycle frame showing the brakework and front
mud-guard held in position by my clip.
Figure 6 is an elevation of one of the screws for clamping the parts of the clip
together.
In carrying my invention into practice I take two pieces of flat steel or other
metal A and A' and bend them flatwise into three half circles as shown at
Figure 2, leaving the flat spaces a2 and as between the two end half circles and
the centre half circle, a hole being pierced through each of the flat spaces a² and
a screw hole tapped in the other flat spaces a³ to receive the two screws s¹ and
which clamp the two halves together, thereby forming the three complete
circles a, a and a as clearly shown at Figure 3. Instead of forming three
complete circles the ends may be square, oval or other shape or one end may be
round and the other square or oval.
To secure my clip in position on the "crown" C of the cycle I place the two
halves of the circle a around the centre portion of the crown and then clamp
them firmly together by the screws s' and s³, leaving the circle a' in front of the
crown and the circle a behind. The circle a acts as a guide for the plunger rod d',
which operates the brake D, and the top end of the front mud-guard F is attached
to the circle a by the pin and nut f, as clearly shown at Figure 5.
"Crown" clips constructed according to my invention are much stronger and
can be manufactured at a considerably less cost. The brake work can also be.
more readily attached or detached, which will be found to be of great advantage.
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 :-
Forming crown clips for cycles from two pieces of flat metal bent by suitable
tools so as to form when placed together edgewise three complete circles or a circle
in the centre and a square or other shaped hole at each end, the said pieces of
metal being held together by screws or their equivalents in the manner and for the
purpose substantially as hereinbefore described and as shown upon the accompanying
sheet of drawings.
