Improvements relating to Cycle Steering Heads.

We, ARTHUR HASKINS, of 12, Laburnum Grove, Beeston, in the County of
Nottingham, Engineer, and CHARLES RILEY GARRARD, of Roseberry Villa,
Breaston, in the County of Derby, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention consists of improvements relating to cycle steering heads, our
object being to provide a simple and effective secret fastening or device for locking
or securing the steering head to the socket of the cycle framing.
In the application of our invention we form a projecting ear or lug at the lower
end of the head clip in a position preferably at right angles to the centre line of
the machine. Immediately beneath the projection from the head clip we form a
similar projection from the upper end of the socket of the cycle framing which
is arranged for the reception of the steering head or stem in the ordinary
manner.
Through the projection from the socket we drill or form a small hole to permit
of the insertion of a common pin or small wire, and we form a semi-circular or
suitable recess in the upper face of the lug or projection of such a depth as to
admit about one half of a steel or other suitable ball preferably of about three
sixteenths of an inch in diameter.
In the adjacent face of the lug or projection from the head clip we form a
recess of a sufficient diameter and depth to receive the ball herein before described,
and also to contain a small spiral or other suitable spring. We also drill a small
hole through the projection to receive the end of the spring and prevent same from
detachment.
To lock the steering head we push the ball into the recess in the head clip
against the resistance of the spring, and turn round the steering head until the
recesses in the clip and the socket coincide with each other. The spring then
forces the ball into the lower recess, and the steering head is thus locked or secured
to the socket.
To unlock or detach the head we insert a small wire through the lower projection,
and thus push the ball out of the aperture. The steering head can then be turned
round and when moved sufficiently far the upper projection will be clear of the
lower, and the ball will be ejected by the spring.
Instead of a ball we sometimes employ a pin, preferably with a rounded
extremity, for locking the steering head to the socket, and we make other modifica-
tions to meet varying requirements, or to suit the particular form of cycle to which
our invention is to be applied.

Improvements relating to Cycle Steering Heads.
We, ARTHUR HASKINS, of 12 Laburnum Grove, Beeston, in the County of
Nottingham, Engineer, and CHARLES RILEY GARRARD, of Roseberry Villa,
Breaston, in the County of Derby, Engineer, 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 consists of improvements relating to cycle steering heads, our
object being to provide a simple and effective secret fastening or device for locking
or securing the steering head to the socket of the cycle framing.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to;-
Figure 1 is a sectional elevation of a portion of a cycle steering head having our
invention applied thereto and Figure 2 is a sectional plan of the same on the
line wa of Figure 1.
The same reference letters in the different views indicate the same parts.
In the application of our invention we form a projecting ear or lug such as A at
the lower end of the head clip in a position preferably at right angles to the
centre line y. Immediately beneath the said projection A from the head clip
we form similar projection B from the upper end of the socket of the cycle framing
which is arranged for the reception of the steering head or stem in the ordinary
manner.
Through the projection from the socket we drill or form a small hole C to
permit of the insertion of a common pin or small wire, and we form semi-circular or
suitable recess in the upper face of the lug or projection B of such a depth as to
admit about one-half of a steel or other suitable ball D preferably of about three
sixteenths of an inch in diameter.
In the adjacent face of the lug or projection A from the head clip we form a
recess of a sufficient diameter and depth to receive the ball D hereinbefore
described, and also to contain a small spiral or other suitable spring E. We also
drill a small hole through the projection A to receive the end of the spring E and
prevent same from detachment.
To lock the steering head we push the ball D into the recess in the head clip A
against the resistance of the spring E, and turn round the steering head until the
recesses in the clip A and the socket B coincide with each other. The spring then
forces the ball D into the lower recess, and the steering head is thus locked or
secured to the socket B as illustrated at Figure 1.
To unlock or detach the head we insert a small wire through the hole C in the
projection B and thus push the ball D out of the aperture in such projection.
The steering head cau then be turned round and when moved sufficiently far,
say to the position indicated by the dotted lines at A (Figure 2) the upper
projection A will be clear of the lower and the ball D will be ejected by the
spring E.
Instead of a ball we sometimes employ a pin, preferably with a rounded
extremity, for locking the steering head to the socket, and we make other modifica
tions to meet varying requirements, or to suit the particular form of cycle to which
our invention is to be applied.
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. A secret fastening or locking or securing device for a cycle steering head,
substantially as described.

page_text: 2. In a fastening for a cycle steering head the use of a ball or pin in combination
with a spring substantially as described and as illustrated.
3. The combination with a cycle steering head of the lugs A and B, the ball D,
and spring C, constructed and arranged, substantially as and for the purposes
described and as illustrated.
