PROVISIONAL SPECIFICATION.
Improvements in Safety and other Bicycles.
I, JABEZ JACKSON of 9 Derby Terrace Lower Ford Street, Coventry, in the
County of Warwick Inventor do hereby declare the nature of my said invention to
be as follows :--
My invention has for its object improvements in safety and other bicycles, which
enables such machines to be left at the curb stone or against a wall or other
position with safety without an attendant and without fear of the machine being
taken away or at any rate not ridden away. This I accomplish as follows:-
To the pivot spindle of the machine I attach a screw or spring collar or nut in
such a manner that when the machine is at rest the said collar or nut is either
screwed upon a moving portion of the pivot or case or liberated so that the spring
may press it upon such moving portion this nut or collar may have a projection or
projections upon its face for taking into a notch or notches upon the moving
portions thus locking them or I may rely upon the friction produced by two
surfaces conical or other. I may also add to this a set pin or locking device to
which a key would fit so that the machine could not be used for riding until it was
unlocked again.
In other cases I may form a slot in the outer & inner case into which a cotter
would fit and I may lock it there. Or I may mount a set screw in the outer case
with a corresponding hole or slot in the pivot or neck into which the screw would
pass when the steering wheel is in line with the machine. This pin or cotter may
be either straight or taper. Instead of a hole I may use a flattened or sunk portion
for the point of the screw. It will be obvious that the position of the screw or nut
or cotter is immaterial so long as the moving or stationary parts are locked together
so that the machine cannot be ridden which is the object of my invention in
connection also with locking the wheel in a straight line or nearly so which may be
accomplished by several notches or slots and thus it is made to stand itself quite
safely.
A sliding collar may also be used having a slot on one side to fit over a fast key
to prevent it from turning or the slot may be in the spindle and the key inside the
hole of the sliding collar but in both cases the effect will be the same.

COMPLETE SPECIFICATION.
Improvements in Safety and other Bicycles.
I, JABEZ JACKSON, of 9 Derby Terrace, Lower Ford Street, Coventry, in the
County of Warwick Inventor do hereby declare the nature of my said invention
and in what manner the same is to be performed to be particularly described &
ascertained in & by the following statement :-
My invention has for its object improvements in safety & other bicycles which
enables such machines to be left at the curb stone or against a wall or other
position with safety without an attendant and without fear of the machine being
taken away or at any rate not ridden away. This I accomplish as follows:-
"To the pivot spindle of the machine I attach a screw or spring collar or nut in
'such a manner that when the machine is at rest the said collar or nut is either
screwed upon a moving portion of the pivot or case or liberated so that the spring
CD 011

page_text: may press it upon such moving portion this nut or collar may have a projection or
projections upon its face for taking into a notch or notches upon the moving
portions thus locking them or I may rely upon the friction produced by two
surfaces conical or otherwise. I may also add to this a set pin or locking device to
which a key would fit so that the machine could not be used for riding until it was
unlocked again.
In other cases I may form a slot in the outer & inner case into which a cotter
would fit and I may lock it there. Or I may mount a set screw in the outer case
with a corresponding hole or slot in the pivot or neck into which the screw would
pass when the steering wheel is in line with the machine. This pin or cotter may
be either straight or taper. Instead of a hole I may use a flatened or sunk portion
for the point of the screw.
It will be obvious that the position of the screw or nut or cotter is immaterial so
long as the moving and stationary parts are locked together so that the machine
cannot be ridden which is the object of my invention in connection also with
locking the wheel in a straight line or nearly so which may be accomplished by
several notches or slots and thus it is made to stand itself quite safely.
A sliding collar may also be used having a slot on one side to fit over a fast key
to prevent it from turning or the slot may be in the spindle & the key inside the
hole of the sliding collar but in both cases the effect will be the same.
In order that my invention may be clearly understood and easily applied to the
various kinds of cycles I have appended hereunto two double sized sheets of
drawings which show various modes of applying the invention to safety bicycles to
which it is especially applicable though as will be readily understood it is applicable
to any similar machines of more than two wheels.
Figure 1, is a side elevation of a safety bicycle showing the machine with an
ordinary steering arrangement and one modification of my invention applied thereto
as will be more fully explained hereafter.
Figure 2, is an enlarged view of the front or steering portion of the bicycle
shewn by Figure 1 broken off.
Figure 3, shews part of a bicycle of different construction with my invention
applied thereto in another form.
Figure 4, is a part elevation of the front portion of a similar bicycle to the
others with my invention applied in another form.
Figure 5, is a section on line 1-2 shewing the clip D in elevation.
Figure 6, shews a part elevation of a bicycle shewing a further modification.
Figure 7, is a similar side elevation shewing a still further modification.
Figure 8, is a front elevation of Figure 7.
Figures 9, 10, & 11 show further modifications to be hereafter described.
In carrying my invention into effect I form upon the steerage the nut b¹ which
is made to screw down against the moving part 2 of the socket the friction thus
obtained thereby retaining the wheel in a parallel position with the machine.
The nut may be locked by the screw pin 63 which may be provided with a
head to receive a key only or with a thumb-screw head. The nut 61 may be made
to slide upon the handle support and may have a spring bearing against it
sufficiently to cause the required amount of friction the nut in that case being
retained out of action when not required by a suitable catch. In the case of the
pivot a shewn in Figure 3 the spring clip D being made to slide on the handle
support and provided with the slot d' which engages with the stud e¹ on the
pivot E the clip being tightened by means of the screw d' but the stud may be
formed upon the clip D & the notch upon the pivot E. In Figure 4 a screw F
having a milled or other suitable head is shewn passing through the handle
support B engaging with a tapped or other hole formed in the enlargement e of
the pivot E or a square face may be formed upon the enlargement against
which the screw would press. In Figure 6 the cotter H is shewn passing through
the inner and outer tube of the handle support and in Figures 7 & 8 a collar K is
formed to slide upon the handle support B and is provided with a nose k¹ which is

page_text: made to engage with the notch k³ attached to the moving part where it may be
secured by the pin . In Figure 9 the pivot is secured from turning by the
bolt M which is attached to the frame of the machine & are made to enter the
sockets mt formed upon the pivot E. In Figure 10 the bolt N is formed upon
the pivot and the socket n' upon the frame and these bolts may be arranged at the
top of the pivot or in the centre as may be desired. Figure 11 shews an hook and
eye arrangement but the hook P may be formed upon the handle support and the
eye p¹ upon the pivot if found more convenient.
Sufficient modifications have now been shewn and described to enable my
improvement to be applied to any and various kinds of machines & my locking
device would be equally applicable in the case of two wheels moving on one
pivot.
It will be evident that a lock & key may be applied to any of the locking
arrangements so as to render it impossible for the various devices to be tampered
with during the absence of the rider.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is :-
1st. The improvements in safety & other cycles such as those herein set forth
and illustrated by Figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 of the drawings
whereby the steering wheel or wheels, is or are fixed in a set position substantially
as and for the purpose set forth.
