PROVISIONAL SPECIFICATION.
Improved Means for Locking Bicycles and other Velocipedes.
I, JOSEPH EVERARD, of 27, Ladypool Road, Sparkbrook, Birmingham,
Warwickshire, Inventor, do hereby declare the nature of this invention to be
as follows:-
--
This invention consists of the hereindescribed improved means for locking
bicycles and other velocipedes in such a way as to prevent their being readily
surreptitiously removed or stolen.
My invention is applied to the front tube or steering head of a bicycle or other
velocipede and is arranged to act upon the steering post passing therethrough
so as to lock the steering post with the front wheel turned at an angle to the
back wheel and thus prevent the bicycle or other velocipede being ridden or
pushed along the road except in a small circle and thus so long as the steering
post is locked in the front tube or steering head with the wheel askew as stated
above the machine cannot readily be surreptitiously removed or stolen.
In carrying out my invention I provide and fix a small boss or pommel on the
outside of the head or front tube of the bicycle or other velocipede and within
this boss or pommel I provide a set screw which is screwed in the boss or pommel
one end of the set screw being made flat or otherwise adapted to act upon the
tubular steering post the said steering post having one or more flats or recesses
or holes formed in or on it with which the said end of the set screw will engage.
The front of this set screw is made square or otherwise suitably formed so as to
be turned by a key and in order to prevent the set screw being removed from
the boss or pommel 1 provide a small screw or peg or other inner projection
in the side of the boss or pommel which engages in a groove or against a shoulder
of the set screw and thus prevents the latter from being removed. Within the
boss or pommel and fitting around the front end of the said set screw I may
provide a small loose washer at the back of which is a spring which forces the
washer forward to the front of the boss or pommel about flush with the end of
the set screw the said washer being prevented from coming out of the pommel
by the edge of the pommel being turned inwardly or by other means. This
washer. serves as an extra security against the surreptitious turning of the set
screw as the washer is about flush with the end of the screw and has to be forced
back by the insertion of the key before the key will fit on to the end of the set
Screw.
When the set screw is screwed outwardly through a short space the steering post
s free and when the set screw is turned in the opposite direction it locks the
steering post as stated above. The key and the end of the set screw on to which
he key fits, as may also the keyhole in the front of the boss or pommel, (when a
keyhole is provided) be made of various forms so as the better to prevent the set
crew being turning except by the proper key.

I, JOSEPH EVERARD, of 27, Ladypool Road, Sparkbrook, Birmingham,
Warwickshire, Inventor, 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 the hereindescribed improved means for locking
bicycles and other velocipedes in such a way as to prevent their being readily
surreptitiously removed or stolen.
My invention is applied to the front tube or steering head of a bicycle or other
velocipede and is arranged to act upon the steering post passing therethrough so as
to lock the steering post with the front wheel turned at an angle to the back wheel
and thus prevent the bicycle or other velocipede being ridden or pushed along the
road except in a small circle and thus so long as the steering post is locked in the
front tube or steering head with the wheel askew as stated above the machine
cannot readily be surreptitiously removed or stolen.
which
will describe my invention by referring to the accompanying drawings on
Fig. 1 is a small scale side elevation of the steering head portion of a safety
bicycle with my invention applied ;-
Figs. 2, 3 and 4 are respectively a side elevation, plan, and front elevation of my
invention;
Fig. 5 is a sectional side elevation of my invention with a portion of the steering
post and steering head to which my invention is fixed;
Fig. 6 shews the key for operating the locking screw of my invention;
Fig. 7 shews the said locking screw separately and
Fig. 8 represents in front elevation and in plan a slightly modified form of my
invention.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawings.
In carrying out my invention.I proceed as follows:-I provide a small boss or
pommel A on the outside of the head or front tube B of the bicycle or other
velocipede through which head or front tube passes as usual the tubular steering
post C. This boss or pommel A is fixed to the front tube B by means of the
former being made with an eye or loop a of a size to fit on to the head or front
tube B which eye or loop a is by preference soldered to the head B before the top
and bottom lugs b¹² are fixed thereon; or when applying my invention to existing
velocipedes I make the eye or loop part a divided as shewn for instance by Fig. 8
SO as to clip the front tube B and be there secured as by the small screws or
pins which secure the divided parts of the eye or loop part a together.
Within the boss or pommel A I provide a set screw E shewn separately by Fig. 7
which is screwed in the boss or pommel A one end e¹ passing through a hole in the
front tube B and being made flat or otherwise adapted to act upon the tubular
steering post C so as to lock the same and prevent its turning. The front end
of the set screw E is by preference made with a square hole and with a central
peg e as shewn or is otherwise suitably formed so as to be turned by the key F
which is made to correspond with the set screw and in order to prevent the set
screw E being removed from the boss or pommel A I provide an inner projection
in the form of a ring a' which is soldered or otherwise fixed in a recess in the front
of the boss or pommel A and the inside a³ which forms the key-hole is rather
smaller than the outside of the set screw E thus preventing the latter from being
removed.
When the set screw E is screwed outwardly through a short space so that the
inner end of the set screw does not bear upon or engage with the tubular steering

page_text: post C the latter is free and can be turned to steer the velocipede as required, but
when the set screw E is turned in the opposite direction its front end e¹ bears upon
or engages with the steering post C and locks the steering post as stated above."
The steering post C may if desired have one or more flats or recesses or holes
formed in it or on it with which the end e¹ of the set screw E will engage.
The key F and the front end e² of the set screw E on to or in to which the key
fits are by preference made of the forms above described, but it will be evident that
these parts, together with the keyhole a³, in the front of the boss or pommel A,
may without departing from the nature of my invention be made of various other
forms to prevent the set screw E being turned except by the particular key which
fits it.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The hereindescribed improved means for locking the steering post of a safety.
bicycle or other velocipede when desired consisting of a boss or pommel A con-
structed substantially as described and shewn for fixing to the front tube or
steering head of the velocipede in combination with a set screw screwed in the boss
or pommel and adapted to engage the steering post and to be turned only by a
special key and means for preventing the removal of the said set screw all
substantially as herein before set forth and shewn.
2. In combination with the front tube and steering post of a safety bicycle or
other velocipede the employment of the means substantially as hereinbefore set
forth and illustrated by the accompanying drawings for locking the steering post
when required.
