PROVISIONAL SPECIFICATION.
Improvements in connection with Velosipedés.
I JOHN MUIR, 90, Lodge Road, Hockley, Birmingham in the County of
Warwick, Cycle Maker, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to that part of a velocipede called the "crown
head," and my improvements consist in forming such crown heads out of a single
piece of weldless steel or other kind of tubing. The lug or socket onto which the
down tube of the ball head fits is "opened out" at the centre of the same piece of
tubing by suitable tools, the two ends of the said crown head are also suitably
formed so as to allow the front forks of the machine to be fixed thereto.

COMPLETE SPECIFICATION.
Improvements in connection with Velocipedes.
I JOHN MUIR, 90 Lodge Road, Hockley, Birmingham in the County of
Warwick, Cycle Maker, 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 has reference to that part of a velocipede called the " crown
head," and my improvements consist in forming such crown heads out of a single
piece of weldless steel or other kind of tubing.
In order that my invention may be clearly understood I have annexed the
accompanying sheet of drawings.
Figs. 1, 2 and 3 shew the various processes through which the piece of tubing
has to pass before it is finished or made into a crown head.
Figs. 4 and 5 are plan and front view respectively of the crown head in a finished
state.
Referring to Fig. 1 I take a piece of tube A of the required length and slit the
ends as shewn at a, a', the said ends are then opened out by suitable tools as shewn
at B, Fig. 2. I then form a slot in the centre of the piece of tubing A by a
suitable milling tool as shown at b, Fig. 3. The said slot b is then opened out by
suitable tools as shewn at c so as to enable the down tube of the ball head of a
velocipede to be fixed therein, and the ends B bent into the required shape for the
front forks to be fixed in, as shewn at Figs. 4 and 5.
I do not bind myself to use a round section of tubing as shewn in the drawings
as any other section will answer the same purpose equally as well.
By making crown heads for velocipedes as herein shewn and specified I am
enabled to manufacture them at a considerable reduction in price, and at the same
time the said crown heads.are much lighter and stronger.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would have it understood
that I do not confine myself to the exact method or details as herein shewn and
described as they may be varied without departing from the principal of my
invention but what I wish to claim is :-
Firstly. Forming the "crown head" of a velocipede out of a single length of
tubing in the manner substantially as herein shewn and described,

page_text: Secondly. Forming the lug c into which the down tube of a bull head of a
velocipede fits out of the same piece of tubing as the ends B into which the front
forks fit in the manner substantially as herein shown and described.
Thirdly. Crown heads of velocipedes formed out of a single length of any known
section of tubing.
