RICHARD LEACH HOLT 3 Adelaide Street Southport Mechanic and ROGER
WALLWORK of 73 and 75 Eastbank Street of Southport aforesaid, Draper, I do hereby
declare the nature of this invention to be as follows:-
My invention is in relation to safety and other Bicycles whereby it enables the
machine to stand in a perpendicular form, while in or out of motion, I attach two
levers on the end of the screw or axil of the back wheel, the said two levers to work
on studs or pins one on each side of the machine, the said levers are bent or cranked
out about 10 inches from each side of the Bicycle wheel. There are also two small
pulleys or wheels working on studs or pins attached to the bottom of the two said
levers. There is likewise a connecting rod or rods attached to the said levers, with
pins or studs at about 3 inches above the centre stud or pins of the Bicycle, which is
carried up to the handle or steering bar of the machine, there is likewise two slots in
the rod, which drops into a stud or pin, which is fastened to the frame work of the
machine a short distance from the handles. There is likewise a handle attached to
the rod or rods, so that when the machine as got in motion, the said rod or rods are
pulled or drawn up, it enables the rider to raise the wheels.or pulleys a sufficient
distance from the floor, and when the machine required to stop the rods are lifted
from one slot to the other and thus allowing the pulleys to come in contact with the
floor thus allowing the machine to stand perpendicular, the rider may go with the
pulleys touching the floor or draw them up from the floor by the rods. I have like-
wise another way of working the motion, the two levers on each side of the Bicycle
have a slot about 3 inches long, so that they can be drawn up by the handles.

Improvements in or relating to Safety or other Bicycles.
We, RICHARD LEACH HOLT, of 3 Adelaide Street, Southport, Lancashire, Machinist,
and.. ROGER WALLWORK, of 73 and 75 Eastbank Street, in Southport aforesaid,
Draper, 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 :-
Our invention relates to Safety and other Bicycles, and its object is to so combine
mechanism therewith that they can be made to keep erect both when stationary and
when in motion, by which means riders may easily get on and off the machines
without difficulty or danger and learners may practice without accident, to themselves
from falling, and besides this, riders using bicycles for military or other purpose can
stand stationary without dismounting and take aim or fire or do any other act
requiring the rider to be stationary or steady, at the same time leaving him both
hands at liberty, the object of our invention being effected without adding greatly to
the weight or complexity of the machine.
Our invention consists in arranging two small wheels or pulleys, by preference,
oue on each side of the machine and connected with its framing so that the wheels or
pulleys may by suitable arrangements be brought and held against the ground when
the bicycle is to be kept erect and lifted away from the ground when the assistance of
these wheels is no longer required, this lowering and lifting being effected either
while the bicycle is stationary or is travelling.
We prefer to mount each small wheel or pulley on a stud or pin upon which they

page_text: can rotate freely, each stud or pin being fixed in the end of an arm or léver, one for
each side of the machine, which can turn freely on the projecting ends of the shaft or
axle for the driving wheel of the bicycle, or these levers may be on studs specially
provided and inserted in the frame work of the machine.
By moving the arms or levers in an arc one way, the wheels are brought against
the floor or ground, and by moving them the reverse way they are lifted sufficient to
be clear from the ground. We prefer to use a small wheel on each side of the machine
though the object of our invention may be obtained to some extent by using one.
wheel on one side, in which case the machine when standing is arranged to lean to
that side on which the wheel is placed.
It is obvious the small wheels may be lifted from, and lowered against the ground
by various arrangements but we prefer to carry them on levers or arms made to
oscillate.
Each arm or lever is connected by a rod and other transmitting mechanism with a
lever bandle or other arrangement near the left steering arm (by preference) by
acting upon which lever handle the small wheels are lifted or lowered.
In some cases owing to the uneven ground upon which the bicycle has to stand or
move the wheels cannot get down to their lowest position and in this case the catch
which holds or prevents the levers or arms carrying the small wheels from lifting,
when they are to be kept against the ground, is made of ratchet pawl fashion to catch
upon teeth.
In some cases each lever or arm is arranged to lower by its own weight to some
extent independently of the other lever or arm, each lever being provided by a ratchet
pawl to catch upon teeth in a segment formed upon or attached to the framing of the
machine. The lever handle when moved one way allows both levers or arms to full
and their pawls to catch when down, and when the lever handle is moved the other
way the pawls are first lifted from the teeth and then the lever arms and small wheels
at the same movement are lifted from the ground.
The modes of carrying out our invention are illustrated by the accompanying
drawings.
Fig. 1 is a side elevation and fig. 2 a plan view of a safety bicycle having our
improvements applied to it, and figs. 3 and 4 are detached views showing details.
a, is the framing; b, the driving wheel; c, the short shaft having bearings upon the
framing for the cranks c', and pedals ; c, is a pulley on the short shaft c, for the
jointed chain c, which also works upon a pulley 63, on the axle 6', of the driving
wheel b. a', is a frame for carrying the front steering wheel d, this frame a¹, is
jointed to the main frame a, at a; e, is the slide rod carrying the brake; f, is the
saddle for the rider.
All the parts above indicated by letters of reference are ordinary well known parts
of a Safety Bicycle.
The axle b', of the driving wheel b, is lengthened, and the boss g¹, of an arm g, is
fitted upon the end of the axle at each side of the driving wheel b, which rotates on
a stationary axle.
The lower ends of these arms g, have each a stud for a small wheel g³, which
are shown in fig. 1 near the ground and in dotted lines as when lifted away from the
ground.
From each arm g, there is a short arm g³, to which one end of a rod h, is jointed
the other end of which rod is jointed to one arm, of a bell crank lever i, which has
its fulcrum i, on the framing or upon a bracket a", secured to the framing a.
As each arm g, for the small pulleys g³, has a short arm 9', and each a connecting
rod h, both rods h, are jointed with the same bell crank lever which is shown by a view
fig. 3 taken in the plane of the line A-B fig. 1.
ay
This bell crank lever has one single armi, and the other arm, of it is double, that
is, one arm comes on one side and the other on the other side of the tubular frame
and bracket a³, so that one arm, can be connected with one rod h, on one side and
the other arm with the other rod h, on the other side.
The single arm i, of the bell crank is jointed with the lower end of a rod i³,
the

page_text: upper end of which has a screw pin, in it, the axis of which screw pin being in a
line with the axis or hinge a³, upon which the frame a', of the steering wheel is hinged
to the main framing a. The said screw pin or swivel, in the top of the rod 3, is formed
with an eye in its end so as to be jointed with one end of a lever j, having its fulcrum
on a stud, in say the side of the left arm k, of the steering handles, or this stud is
upon a bracket, secured to the steering arm k, that end of the lever j, jointed to
the screw it, when up or down being in about the same line as a line prolonged from
the axial line of the hinge or joint a, between the steering wheel framing a', and the
main framing a.
The front view of the arms of the steering wheel handles with the
lever j, for actuating the rod 3, is shown by fig. 4.
When arranged as above described the screw it, at the upper end of the rod ³,
forming the joint eye, will be partly screwed and unscrewed (say to the eighth part
of a turn) as the steering wheel d, is oscillated to and fro.
To the hand lever j, another short lever j³, is jointed at it, which has only a small
amount of movement, as there is a stop to limit its movement in each direction and a
flat spring j is secured to the lever j, the free end of which presses the catch end jo,
of the short lever j³, towards the steering wheel handle k.
The catch j, when the lever j, is at its highest or lowest position is forced by the
spring, above or below a projection j', formed upon the bracket j, for the fulcrum
pin and the handle end of the small lever j', has to be pressed toward the steering
wheel arm k, before the catch jo, is released.
The combined levers j, and j³, are shown detached and on an enlarged scale by
figures to be hereinafter described.
"
The levers j, and j³, can be actuated by the left hand to lower and lift the small
wheels g'.
The catch end, of the lever may be made bevelled to take hold of pawl or
ratchet teeth formed upon the face of the projection j, upon which it catches, so that
the wheels will be held at the lowest position to which they can descend, which may
not be in all cases to their lowest position owing to the uneven ground the bicycle
may be standing upon at the time the wheels are lowered.
Fig. 5 is a diagrammatic side elevation showing another modification of our
invention.
Fig. 6 is a top view in the plane of the line C-D fig. 5, and fig. 7 is a front view
of the same.
Fig. 8 is a front or flat view, and fig. 9 an edge or top view of the actuating handles
shown enlarged and detached.
The parts i, i, i³, i³, i¹, a³, j, j¹, k, j², j³, j*, j³, jo, and j', shown in these figures
are the same as those hereinbefore described and shown in figs. 1, 2, 3 and 4.
The difference between the modification illustrated by figs. 1 to 4 and that shown
by figs. 5 to 11 is in reference to the connection of the rods h, with a short arm g³,
from the arms g, carrying the small wheels g³.
In the end of the short arm a stud 9', is secured (see figs. 5, 10 and 11) upon
which a single or double pawl g', is jointed (one a little longer than the other).
The end of this pawl or pawls g', rest upon a segmental ratchet toothed bracket g*,
secured to the framing a.
If the arm g, is lowered the pawl 9³, passes over the teeth and prevents the arm g,
from moving back.
The lower end of the rod h, is jointed with the stud 9*, by means of a short slot /¹,
which thus allows a little movement in the rod h, before acting upon the stud 9*.
On one side of the lower end of the rod h, there is another shorter slot h³, than the
first named slot h³, and a pin h³, secured in one side of the boss of the pawl g', enters
the small slot h².
When the rod h, is lowered the smal slot A', allows the pawl g', to lift freely to
pass over the ratchet teeth in the segment 96, but when the rod h, is drawn up one
end of the short slot, first comes against the pin h³, in the boss of the pawl and
thus lifts the pawl clear of the ratchet teeth, the stud g, then comes against the lower

ground.
There is a rod h, pawl 9, and ratchet segment 9°, for each arm g, on each side of
the machine.
With this arrangement one small wheel g², can come a little lower than the other if
the ground upon which the Bicycle stands is uneven.
The long slots h¹, limit the movements of the arms g, so that they cannot get past a
position vertically under the axle b¹.
Fig. 12 is a diagrammatic side elevation of a Bicycle suitable for. ladies.
It is constructed in the same manner, as that shown by figs. 1 and 2 except in the
form of the framing a, and in the mode of transmitting the movement from the
actuating handles j.
c, represents the short shaft for the pedal cranks.
It will be seen that the movement is transmitted from the rod is, through a bell
crank lever is, and a rod h, and bell crank lovers i, 3, and rods h; these bell crank
levers having their fulcruins on the framing a, or upon brackets secured to the
framing.
Fig. 13 is a side elevation and fig. 14 is a view in the plane E-F fig. 13 illustrating
the mode of arranging the transmitting mechanism from the actuating. handles
and 3, when the axis as, of the frame a, for the steering wheel oscillates in a sleeve
forming part of the framing.
In this case the rod 3, at its upper end is jointed simply (no screw ", being
required) with the end of the lever j.
This rod is, is formed with a part is, having a hole so that it can slide freely up and
down the shaft or axis a', of the steering wheel frame.
The lower end of the part is, is formed by a hoss 7, with a groove as if for a
clutch fork lever, and it has a hole through it, to slide freely up and down the
sleeve a*.
The groove in the boss i?, engages with a stud or a bowl on a stud in the end of
one arm of a bell crank lever i, i, having its fulcrum i¹, on a bracket a³, secured upon
the framing.
It will thus be seen that the boss part i, can slide up and down the sleeve a', as it
is moved by the actuating handle j, and j³, at the same time can oscillate to and fro
with the axis a, of the steering wheel, and will keep up a connection with the stud in
the bell crank lever i, in every position.
In some Bicycles a helical spring is introduced on the axis or shaft a, of the
steering wheel frame between the points marked 1 and 2 and 3 and 4 fig. 13, and this
causes the axis a³, of the steering wheel, to move up and down in relation to the
sleeve a, of the framing, or the sleeve a, moves up and down the axis a', of the
steering wheel framing.
In such case, the fulcrum of the bell crank lever i, i, is or may be carried upon a
bar I, shown in dotted line, that is guided and arranged to slide in a line parallel to
the axis a³, of the steering wheel frame in a bracket secured to the main framing a.
The lower end of the bar l, is made with an open jaw to take on each side of a
collar a, concentric with the axis a*.
Thus arranged the fulcrum of the bell crank lever i, i?, will move up and down
with the axis or shaft a³, of the steering wheel frame, and will always remain at the
same distance from the steering wheel arm k, and the oscillating movements of the
axis a, in its lengthway will not have any effect, or but little in moving the bell
crank lever i, i, upon its fulcrum i'.
