PROVISIONAL SPECIFICATION.
Improved Means for Locking the Heads of Cycles of all kinds.
I, ALFRED JOHN RILEY of 88, Great King Street Birmingham in the County of
Warwick Cycle Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a new and improved method of head lock for locking
the upper part or head of a cycle whether a bicycle or tricycle when not in use,
for my purpose I bore a hole of any convenient diameter in any part of the tubes
or lugs forming the ball head of the machine that is to say the outer and inner
tubes of the neck of the fork within which is the handle tube or bar, at right
angles to the hole and formed either integral with the outer tube of the ball head
or suitably attached thereto is a short tubular projecting piece and at the base
thereof or within same is located a screw threaded nut cast therein or otherwise
attached, a movable pin of any suitable length, size, and shape and correspondingly
screw threaded works through the nut by means of a key and thus forms a bolt or
lock and in order that it may always be retained within the said nut the inner end is
enlarged with a head or has a fixed nut thereon so that it cannot be entirely screwed
out. Moreover it is prevented from being screwed in too far by affixing a collar or
washer upon the key attachment end and also by its contact against the neck portion
of the handle bar.
Thus when required to lock the head of the cycle by placing the key upon the
square or other shaped end of the movable pin or bolt it is screwed through the nut
the end passing into the hole in the telescopic tube and is pressed firmly against the
inner tube or handle bar so that the head is prevented from being turned for the time
being either to the right hand or to the left until released by unscrewing the pin
or bolt.
The locking arrangement may be made of any metal and forms a neat and
effective method for the purpose. The key hole may be provided with a cap suitably
attached to keep out dust and dirt.
When preferred I may make the key with wards thereon to fit corresponding wards
in the locking arrangement.
I, ALFRED JOHN RILEY, of 88 Great King Street, Birmingham, in the County
of Warwick, Cycle Manufacturer, 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 :-
Reference being had to the drawings accompanying this specification and to the

page_text: figures and letters shewn therein, in which
Figure 1 represents in elevation the inner tube rising from the fork which carries
the ball head and handle bar.
Figure 2 represents in elevation the outer tubular portion that fits over said
inner tube.
Figure 3 represents in elevation another view of the outer tubular portion.
Figure 4 represents the above figures in sectional elevation.
Figures 5 and 6 represent the adjustable screw pin and cap or cover hereinafter
referred to, and Figure 7 is a key for operating said screw pin.
Similar letters of reference indicate like parts upon the several figures shewn.
My invention relates to a new and improved method of head lock for locking the
upper part or head of a bicycle or tricycle when not in use. For my purpose I bore
a hole of suitable diameter in any convenient part of the tube A or either of the lugs A
forming the ball head of the machine that is to say the outer tube A or lugs A¹ and
inner tube B of the neck of the fork within which is the handle tube or bar.
Attached to or formed integral with the outer tube A of the ball-head or lugs A',
and at right angles thereto is a short tubular projection C and at the base thereof
or within same may be located a screw threaded nut cast therein or otherwise
attached or preferably as shewn the said projection C is suitably wormed, a movable
pin D of a corresponding size and correspondingly screw-threaded works within the
tube C or the aforesaid nut by means of a key E fitting onto the square end of the
screw-pin D and in order that said screw-pin may be prevented from screwing
entirely out of tube C. The inner end is enlarged with a head D' or is provided
with a fixed nut so that it is retained in place, the screw-pin D is prevented from being
screwed in too far by affixing a collar or washer upon the key attachment end if
necessary.
Thus when required to lock the head of the cycle by placing the key upon the
square or other shaped end of the movable pin or bolt D it is screwed through
the tubular portion C (or the inner nut), the enlarged end D' is projected into a
hole or indent F in the inner tube B and is thus firmly pressed against said inner
tube or handle bar so that the head is held and prevented from being turned either
to the right hand or to the left until released by unscrewing the pin or bolt with
the key.
This locking arrangement may be made of any suitable metal and forms a neat
and effective method for the purpose intended, the key hole portion is provided with a
suitable cover or cap G to keep out dust and dirt.
If desired the key may be made with wards therein to fit corresponding wards in
the locking arrangement.
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 1
claim is-
The herein described improved means in combination for locking the heads of
cycles by the application and use of a movable screw-pin or bolt D working in its
tubular projection C, said projection C being situated upon the outer tube A of the
balt head or upon either of the lugs A' said screw-pin or bolt D being operated by a
key E as and for the purpose set forth and illustrated.
