We, WILLIAM ALLDAY, of Springfield Moseley, in tho County of Worcester,
and EDMUND ALLDAY, of Spring Coppice Knowle in the County of Warwick
Manufacturer do hereby declare the nature of this Invention to be as follows:-
Our invention has especial reference to the locking of the handle bars of safety and other
bicycles so as to prevent the turning of the said handle bars when the said bicycles are
placed against a wall or other vertical support, but our invention may be applied to the
locking of the handle bars of tricycles and other velocipedes.
Our invention consists of the construction and arrangement or combination of parts
hereinafter described for locking the steering column to which the handle bar is
connected in the steering socket or head tube of the bicycle or other frame.
We will describe our invention in connection with the locking of the handle bar of
a safety bicycle.
We form on one side of the top lug of the head tube or steering socket of the bicycle
frame a slotted or forked projection and we form on the side of the ball head clip
a corresponding slotted or forked projection the slots of the said two projections
coinciding when the steering and rear or driving wheels of the bicycle are in line.
joint in the slot of the projection on the top lug of the head tube a short arm carrying at
its outer end a tubular sleeve or bolt which is urged towards the inner or joint end of
the short arm by a coiled spring.
When the parts are in their normal positions that is, when the handle bar is unlocked
and free to turn, the short jointed arm is in its turned down position in the slot of the
projection on the top lug of the head tube and is parallel to the said head tube,
the inner end of the spring tubular sleeve or bolt on the end of the said jointed arm
occupying a recess or seat in the underside of the slotted projection and securing the
jointed arm in its unlocking position.
When it is desired to lock the handle bar and thereby prevent it from turning, the
slot in the projection of the ball head clip is made to coincide with the slot in the
projection on the top lug of the head tube. The spring sleeve or bolt of the short
jointed arm is disengaged from the underside of the projection on the said top lug
and the said short jointed arm is raised and turned through a semi-circle. The upper
end of the short jointed arın now occupies the slot of the projection on the ball head
clip. The spring sleeve or bolt is now opposite and takes into a recess or seat in the
top of the said projection on the ball head clip. The handle bar is thus locked and
prevented from turning.
The application of our invention to the locking of the handle bars of tricycles and
other velocipedes differs in no essential respect from its application to the locking of the
handle bar of a safety bicycle as herein before described.

Improvements in Locking the Handle Bars of Bicycles, Tricycles,
and other Velocipedes.
We WILLIAM ALLDAY of Springfield, Moseley in the County of Worcester, manufac-
turer and EDMUND ALLDAY of Spring Coppice, Knowle, in the County of Warwick,
Manufacturer do hereby declare the nature of our invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
Our invention has especial reference to the locking of the handle bars of safety and
other bicycles so as to prevent the turning of the said handle bars, when the said
bicycles are placed against a wall or other vertical support, but our invention may be
applied to the locking of the handle bars of tricycles and other velocipedes.
Our invention consists of the construction and arrangement or combination of parts
hereinafter described for locking the steering column to which the handle bar is
connected in the steering socket or head tube of the bicycle or other frame.
We will describe our invention in connection with the locking of the handle bar of
a safety bicycle.
We form on one side of the top lug of the head tube or steering socket of the bicycle
frame a slotted or forked projection and we form on the side of the ball head clip a
corresponding slotted or forked projection, the slots of the said two projections
coinciding when the steering and rear or driving wheels of the bicycle are in line. We
joint in the slot of the projection on the top lug of the head tube, a short arm carrying
at its outer end a tubular sleeve or bolt which is urged towards the inner or joint end
of the said short arm by a coiled spring.
When the parts are in their normal positions, that is, when the handle bar is
unlocked and free to turn, the short jointed arm is in its turned down position in the slot
of the projection on the top lug of the head tube and is parallel to the said head tube,
the inner end of the spring tubular sleeve or bolt on the end of the said jointed arm
occupying a recess or seat in the underside of the slotted projection and securing the
jointed arm in its unlocking position.
When it is desired to lock the handle bar and thereby prevent it from turning, the.
slot in the projection of the ball head clip is made to coincide with the slot in the pro-
jection on the top lug of the head tube. The spring sleeve or bolt of the short jointed
arm is disengaged from the underside of the projection on the said top ing and the
said short jointed arm is raised and turned through a semi-circle. The upper end of
the short jointed arm now occupies the slot of the projection on the ball head clip.
The spring sleeve or bolt is now opposite and takes into a recess or seat in the top of
the said projection on the ball head clip. The handle bar is thus locked and prevented
from turning.
Figure 1 of the accompanying Drawing represents in elevation; Figure 2
partly in elevation and partly in section and Figure 3 in plan, locking
inechanism constructed according to our invention for locking the handle bar of
a safety bicycle the said handle bar being represented unlocked; Figure 4 represents
in elevation the said handle bar locked and Figure 5 represents the tubular sleeve or
bolt of the jointed arm, in its withdrawn position either for the locking or unlocking
of the handle bar.
The same letters of reference indicate the same parts in the several Figures of the
Drawing.
a is the handle bar, the steering column 6 of which works in the steering socket or
head tube c as usual; d is the ball head on the steering column 6 and surmounting
the top luge on the head tube or steering socket c. On one side of the said top lug e of
the steering socket c is a slotted or forked projection f and on the ball head clip d
of the steering column b is a similar slotted or forked projection g, the slots in the two

page_text: projections f, g coinciding when the steering and rear or driving wheels of the bicycle
are in line as seen in Figures 2 and 4. In the slot of the projection f on the top lug e,
a flat short arm h is jointed at h2, the said arm being capable of motion through a
semi-circle on its joint. On the outer end of the said jointed arm h is a tubular bolt
or sleeve i urged towards the joint end of the said arm by a coiled spring situated
between the said tubular bolt and arm (see the sections Figures 2 and 5). The inner
end of the tubular bolt iis conical and the outer face of each of the slotted
projections f, g has a seat or recess made in it for receiving the conical end of the
tubular bolt i. The seat or recess in the projection f is marked f and that in the
projection g marked g'.
Figures 1, 2 and 3 represent the parts of the locking mechanism in their normal
positions, in which positions the handle bar a is unlocked and its steering column bis
free to turn in the steering socket c. In the unlocked position of the parts, the short
jointed arm his in its turned down position in the slot of the projection f of the lug e
of the steering socket c and is parallel to the said steering socket, the inner conical
end of the spring tubular bolt or sleeve à occupying the recess or seat in the
underside of the slotted projection f and thereby securing the jointed arm i in its
unlocking position.
In order to lock the handle bar a and thereby prevent the steering column 6 from
turning in the steering socket c the slot in the projection g on the ball head clip d is
made to coincide with the slot in the projection on the top lug e of the steering socket
as represented in the drawing. The spring sleeve or bolt is by a downward pull
disengaged from the seat f in the slotted projection f and its spring compressed. The
jointed arm h is now at liberty to move and the said arm is raised and turned through
a semi-circle into the position represented in Figure 5. The spring sleeve or bolt i
is now opposite the recess 2 in the projection on the ball head slip d and by
releasing the said spring sleeve or holt it snaps into the recess or seat g of the said
projection as represented in Figure 4, and thus locks the handle bar and prevents
it, turning. To unlock the handle bar it is only necessary first to lift the spring sleeve
or bolt i vertically from the seat g² as represented in Figure 5 and then to turn the
jointed bar h through a semi-circle into the position represented in Figures 1 and 2
and re-engage the spring sleeve or bolt i with the seat of the projection f.
The application of our invention to the locking of the handle bars of tricycles and
other velocipedes differs in no essential respect from its application to the locking of the
handle bar of a safety bicycle as hereinbefore described and illustrated in the
accompanying Drawing.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed, We declare that We claim
as our invention :-
The improvements in locking the handle bars of bicycles, tricycles and other
velocipedes hereinbefore described and illustrated in the accompanying Drawing; that
is to say, locking mechanism consisting essentially of two forked or slotted projections
one on the head tube or steering socket and the other on the steering column carrying
the handle bar, and a jointed bar working in the slot of the head tube projection and
capable of a semi-rotation for locking and unlocking the handle bar, the said jointed
arm being used in combination with a spring sleeve or bolt for engaging, when the
slots in the two projections are made to coincide with a seat or recess in the slotted
projection on the steering column for locking the handle bar, and for engaging with a
similar seat or recess in th other slotted projection for securing the jointed arm in
its unlocking position substantially as described and illustrated.
