for the same.
JOHN EDWARDS Carpenter and Joiner 30 Coolinge Road Folkestone Kent do
hereby declare the nature of this invention to be as follows:-
Is to provide and make a bicycle in such a way so that the position of the rider is
the same as on, the high bicycle, but lower down behind the wheel not on the top,
80 that a smaller wheel can be used, it will also allow of the front wheel being
driven with one chain and will be reversible, by reversing the handle har and
saddle bracket, it can also be made with open frame to allow of its being ridden by
a lady.
I. I make an improved double frame of a diamond elliptic, or other form to suit
the size of wheels required but in all cases it will have a vertical stem, abbutting on
the rear part of front wheel, the frame of whatever form will extend, from the
said stem to the center of front wheel both the lower and upper part of frame,
the said upper part of front frame, will have a socket, to carry the saddle bracket,
and the lower part of frame, will be connected to the said stem, by a crank spindle
bracket, it will also extend, a certain distance, behind the aforesaid stem, and will
finish in the form of one half of a knuckle joint, the lower part of back frame
from the centre of back wheel-will extend forwards to the said knuckle of front
frame, and will be connected by a double ball bearing, the upper part of back
frame will extend from the centre of back wheel, to the said front frame were it
enters the vertical stem to which the front frame will be fixed, the upper part of
back frame will be connected to the said stem by a double ball bearing, the bottom
end of back frame will be connected to the lower part by a double joint to allow,
of the bottom part of frame carrying the bottom end of upper frame with it when
steering, it will also have a socket near the top end to carry the saddle bracket,
vertical stem, to the.
there will also be a stay extending from the lower part
upper part of back frame, above the back wheel, if required, it can be double, to
pass round the wheel, to the frame lower down, and to which it would be fixed in
both cases.
The other end of said stay, will be connected, to the said vertical
stem, by a double ball bearing, thus forming a vertical or rudder joint.
II. I also make an improved, steering as follows, the handle bar, is made to
telescope and is also detachable by a barrel union, or other connection. The said
handle bar, being connected to a steering rod, extending through, the whole length
of the vertical stem passing through the bottom a certain distance, and would be
connected to the said vertical stem, at both ends, by the aforesaid, double ball
bearings, connected with the aforesaid stay and back frame. Attached to the
bottom end of said steering rod; is a lever extending backwards the said lever
having a tee or cross-shaped sliding peice fitting into a lever extending forwards
from the knuckle of back frame, so that by turning the handle to the right or left,
the levers are moved sideways which causes the wheel, to take the form of an
obtuse angle, in which position, they will pass round any curve required, the tee or
cross peice, sliding along the front lever to alow of its following, the radius of the
back frame lever, thus preventing any blocking, by the levers being drawn apart,
there will also be a spring attached, to the back end of front lever, to bring the .
lever's in a straight line when the handle bar is released, the reversing action as
similar double action lever's connected to the aforesaid front lever and steering rod.
It can also be steered by two lever's connected to the aforesaid stem and saddle
bot

the wheel by a chain which is drawn tight by the action of an Archimedian screw
and nut fixed in one of the handles the object of the double ended brake, is, should
the chain brake, the bottom end of brake, would be pressed on the wheel, by the
action of the spring for the purpose of drawing the handle back, when released by
the hand, at the same time, pull the top end of brake, off the wheel, there will also
be a blocking arrangement to keep the brake on the wheel, consisting of an hollow
cylinder, and thumb peice, attached to the aforesaid handle, and a rachet fixed to
the handle bar it can also be made to act as a lock to block the brake on the
wheel.
IV. I also make an improved detachable crank, the said crank fitting on the
spindle, in the form of an eccentric, in which form it will grip the spindle when
pressure is applied, there is a set screw on one side, to prevent it working loose by
back
pressure.
V. I also make an adjustable self grip treadle, to be drawn to the foot by the
action of an Archimedian screw and nut.
VI. I also make an improved ball bearing by which the weight is suspended
and not supported as by those in use at present it will also be dust and water.
proof.
VII. I also make an antifriction ring it is made in the form of a channel or
groove, and is perferated to fit over teeth of pulley, when in position is in the
form of an eccentric extending towards the crank pulley, so that the chain in
passing round it, can only engage, with two or three teeth, of the small chain
pulley, thus reducing the friction, and encreasing the leverage, by pulling from a
larger diamater.
VIII. I also make an improved two speed pulley, in this case it would be a
pulley simular to the crank pulley, but the flange would be all on one side, and
would have intermediate hollow teeth when in position for speed, it would fit on
the teeth of the upper part, of small pulley, the wide spaces of chain fitting over
the said hollow teeth, and would be cut away between the said hollow teeth, to allow
of the intermediate teeth, of the small pulley, engaging with the narrow, spaces of
chain, the said speed pulley, would be attached, to the front frame, and connected, to
the crank spindle bracket by a lever or arm, so that when being raised or lowered,
for speed or power, it would keep an equal distance on account of the chain having
to be a dead length.
IX. By my invention the position of the rider is the same as on the high bicycle
but behind the wheel, not on the top, and the weight of the rider, will be suspended
between the wheels and not supported as by those in use at present the same to be
further described and shown by drawing.

COMPLETE SPECIFICATION.
Improvements in Velocipedes and Chain Wheels or Pulleys
for the same.
JOHN EDWARDS Carpenter and Joiner 30 Coolinge Road Folkestone Kent 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 :-
Is to provide and make a bicycle in such a way so that the position of the
rider is the same as on the high bicycle but lower down behind the wheel, not on
the top, so that a smaller wheel can be used. It will also allow of the front wheel
being driven with one chain, and will be reversible by reversing the handle bar
and saddle bracket, it can also be made with open frame, to allow of its being
ridden by a lady.

page_text: In working out my invention, I dispense with certain joints movements and
parts, and replace them by others as required, the same being described and shown
by drawings-but in all cases the principle will be the same.
I. I make an improved double frame of a diamond elliptic or other form to suit
the size of wheels required but in all cases it will have a vertical stem, abutting
on the rear part of front wheel as at A Fig. 1 & 2. The frame of whatever
form will extend from the said vertical stem to the centre of front wheel, both the
lower and upper part of frame as at B. Fig. 1. The said upper part of frame
will have a socket to carry the saddle bracket as at C. Fig. 1. and the lower part
of frame will be connected to the said stem, by a crank spindle bracket, at
D. Fig. 1. It will also extend a certain distance behind the aforesaid stem, and
will finish in the form of one half of a knuckle or ball joint as at E. Fig. 1 & 2
& 3 & 4. The lower part of back frame from the centre of back wheel will
extend forward to said knuckle or ball joint of front frame as at F. 1 & 2 & 3 & 4.
The upper part of back frame will extend from the said centre of back wheel,
to the aforesaid front frame where it enters the vertical stem to which the said
be a
front frame will be fixed as at G. Fig. 1. The upper part of back frame will be
connected to the said stem by a double ball bearing, the bottom end of said back
frame, will be connected to the spindle by a bush or ball bearing, there will also
vertical and horizontal movement as at H. I. Fig. 1. to allow of the
aforesaid bottom part of frame carrying the bottom end of upper frame with
it, when steering as at J. Fig. 1. The said upper frame will also have a socket
There will also
near the top end to carry the saddle bracket as at K & L Fig. 1.
be a stay extending from the lower part of aforesaid vertical stem, to the upper
part of back frame above the back wheel as at M. Fig. 1. if required it can be
double to pass round the wheel lower down the frame and to which it would be
fixed in both cases, the other end of said stay will be connected to the said
vertical stem, by a double ball bearing, thus forming a vertical or rudder joint
as at N. O. Fig. 1. I also make them without the joints marked H & I Fig. 1. In
this case there will be a slot or quadrant on the bottom end of upper part of said
back frame, the lower part of said back frame would work in said slot by a
V shaped edge roller attached to the aforesaid spindle I also make them without
the joint marked E. Fig. 1 & 2 & 3 & 4 or the joints marked H & I Fig. 1. In
this case the back frame would be in one peice, and swing on the vertical stem
only, they could also be made without the lower part of frame or stay
marked E & F. M. Fig. 1. by making the frame as at P. Fig. 1. The object of
this is to keep the frame within the thickness of wheel tyre to give more clearance
when steering if required they could be made as shown by lower dotted line Fig. 1.
In this case the riders feet would pass over the frame.
II. I also make an improved steering as follows the handle bar is made to
telescope and is also detachable, by a barrel union or other connection as
at Q. Fig. 1. the said handle bar being connected to a steering rod extending
through the whole length of the aforesaid vertical stem, passing through the
bottom a certain distance and would be attached to the said vertical stem at both
ends by a double ball bearing, connected with aforesaid stay and back frame.
There is also attached to the bottom end of steering rod an adjustable lever
extending backwards as at R. Fig. 2 & 3 & 4. the said lever having a tee or
cross shape sliding peice as at S. Fig. 2 & & 4 fitting into an adjustable
lever, extending forwards from the knuckle or joint of aforesaid back frame as
at T. Fig. 2 & 3 & 4 so that by turning the handle to the right or left, the
levers are moved sideways as at Fig. 4. which causes the wheels to take the
form of an obtuse angle, in which position they will pass round any curve
required, the tee or cross peice sliding along the front lever to allow of its
following the radius of the back frame lever, thus preventing any blocking by
the levers being drawn apart, there will also be a spring attached to back
end of aforesaid front lever as at U. Fig. 2 & 3 & 4. to bring them in a straight
line when the handle bar is released,

page_text: The reversing action will be as follows attached to the aforesaid front lever
ie a beveled spur wheel-à certain distance above is a simular spur wheels but
fixed to the aforesaid steering rod, the said beveled spur wheels being horizontal,
there will also be a simular spur wheel but smaller-connected to the front frame-
but not engaging with the teeth of the aforesaid spur wheels-to reverse the
action the pin or bolt connecting the said lever to steering rod is removed―
and the vertical spur wheels is moved into position to gear with the aforesaid
horizontal spur wheels-so that on turning the handle bar to the right or left
the spur wheels is carried with it which causes the upper part of the vertical
spur wheel to go in the same direction-the bottom half moving the reverse
way and carring the spur wheel attached to the said lever with it I also make
them to steer by tilting the saddle to the right or left, the action will be as
follows, the saddle is fixed to a tube, the said tube telescoping the saddle bracket,
the tube also having a lever extending downwards there will also be, a lever, fixed
to the vertical stem, the said lever extending backwards, to engage with the lever
connected to the aforesaid tube, so that by tilting the saddle to the right or left
the lever connected to vertical stem is moved sideways which causes the wheel to.
take the same position, as when moved by the lever attached to the aforesaid
steering rod I also make them as a single steerer, in this case the only joints
required would be on the back spindle and H. I. Fig. 1, and a curved slot as at V.
Fig. 3.
III. I also make an improved brake it is double ended as at Fig. 5. A. is the
brake, B. is a pin fixed in same, C. is a double plate fixed to back frame, said plate
having a curved slot as at D. E is a roller fixed in brake, F is a pin, fixed in
back frame under the roller, to hold brake up in slot, said brake will be applied
to the wheel by a chain, which is drawn tight by the action of an Archimedian
screw and nut fixed in one of the handles, the object of the double ended brake
is, should the chain part, the bottom end of said brake would be pushed off the
pin E. by the spring G. and drop in the slot and thus check the wheel, the
spring G. Fig. 5. also being for these of drawing the handle back when
released by the hand, and pull the
off the wheel, there will also be a
blocking arrangement to keep the brake on the wheel, consisting of an hollow
cylinder and thumb peice attached to the aforesaid handle, and a rachet fixed
to the handle bar, the action will be as follows, the said handle would be turned
forward carrying the said cylinder and thumb peice with it, said thumb peice
engaging with the rachet fixed to said handle bar, and so take the pressure off
the hand, it can also be made to act as a lock, to block the brake on the wheel,
to prevent the machine being ridden, untill the said brake is released.
IV. I also make an improved detachable crank, the said crank fitting on the
spindle, in the form of an ecentric, in which form it will grip the said spindle
when pressure is applied, there is a set screw on one side, to prevent it working
loose, by back pressure, the said crank and set screw being shown at Fig. 6.
V. I also make an adjustable self grip treadle, to be drawn to the foot by the
action of an Archimedian screw and nut.
VI. I also make an improved ball bearing by which the weight is suspended
and not surported as by those in use at present, it will also be dust and water proof,
the same being shown at Fig. 7.
VII. 1 also make an antifriction ring circular or elliptic, to allow of its being
used in conjuction with either shape chain pulley, it is made in the form of a
channel or groove, and is perforated to fit over the teeth of pulley-when in
position it is in the form of an ecentric extending towards the crank pulley, so that
the chain in passing round it can only engage with two or three teeth of the small
chain pulley thus reducing the friction and increasing the leverage by pulling from
a larger diameter.
VIII. I also make an improved two speed pulley, in this case it would be similar
to the crank pulley the flange being on one side only, and will have intermediate
hollow teeth when in position for speed it will fit on the teeth of the upper or

page_text: Lower part of small pulley as prefered, the wide spaces of chain fitting over the
said hollow teeth, the said flange will be cut away between the aforesaid hollow
teeth, to allow of the aforesaid intermediate teeth of the small pulley engaging
with the narrow spaces of chain, I also make them as a double pulley one part
will be same as ordinary chain pulley, the other part will have rollers simular
to a chain, said rollers engaging with teeth of small pulley, the said speed
pulley will be attached with the front frame and connected with the crank spindle
bracket, by a lever or arm, so that being raised or lowered for speed or power it
will keep an equal distance on account of the chain having to be a dead length.
The principal features of this invention are, the self contained or continuas
frame single or double steering, between the wheels by paralell levers, and spring
spur wheels or levers connected to saddle and vertical stem, double ended self
acting brake, self grip crank, suspended ball bearing, front or rear driving and
antifriction ring.
Having now particularly described and asertained, the nature of my said inven-
tion and what manner the same is to be preformed, I, declare what I claim
is as follows
