Improvements in Velocipedes and Attachments thereto.
WILLIAM GEORGE HARTNOLL, of 65, High Street, Barnstaple, Builder, and JOHN
BEER JONES, of 117, Boutport Street, Barnstaple, Printer, do hereby declare the
nature of this invention to be as follows:
Our invention has for its object the use of a connecting rod and cog wheels
instead of the use of a chain for the propelling of velocipedes.
We propose to use two cog wheels, one of which is attached to the driving axle
of the machine, the other is attached to the framework just behind it and geared
into each other. To the latter wheel we attach a connecting rod by means of a
pin or crank. This connecting rod is attached to a crank or wheel on the hub or
axle of the hindermost wheel of the machine. To prevent the bending of the con-
necting rod, to the side stay of the machine we affix vertical guides, with or without
rollers. These guides to have sufficient space to allow the rod to work.
Where greater speed is required, we propose to have four cog wheels. One to
be attached to the driving axle of the machine; another to be attached to the
framework just behind it and geared into each other. On the face of the latter
wheel we attach two smaller cog wheels, one in the centre and the other in a direct
line above it, and geared into the centre wheel. To the centre wheel we attach a
connecting rod by means of a pin or crank. The other end of this connecting rod
is attached to a crank or wheel on the axle or hub of the hindermost wheel of the
machine. To prevent the bending of the connecting rod, to the side stay of the
machine we affix vertical guides, with or without rollers. These guides to have
sufficient space to allow the rod to work.
The brake for this machine passes down through the upright part of the handle
bars and the ball head of the machine, and consists of two rods or hollow tubes,
which work into each other by means of an internal and external screw thread.
The top rod passes up through the centre of the top of the handle bars, and is
worked by a crank handle or wheel. This top rod is prevented from working
upwards by a thin metal plate fastened on the top of the handle bars, and fitted
into a necking or grove in the rod. These rods are guided at intervals by metal
rings. A portion of the lower end of the bottom rod is formed square in section,
which fits into a square socket and so prevents the brake from turning round, and
is connected to the metal plate by which the brake is attached. To apply the brake,
the crank handle or wheel is revolved, which forces the brake downwards by means
of the screws.
The seat pillar for this machine would be supported in the centre down stay of
the machine by a spiral spring, at the top of which we have a metal disc, upon
which rests the seat pillar. To guide the seat pillar, we insert a metal pin or
screw across the down tube of the machine. On each side of the seat pillar we
have a slot, which allows for its up and down action. To regulate the height of
the seat pillar, we have two rods or tubes, which work into each other by means of

page_text: an internal and external screw thread, with a metal disc attached to the top and
bottom of these rods, the bottom disc resting on a cross pin or pins.
In other cases we have a seat pillar with a double tube, which is inserted in the
down stay, the outer tube being clamped or tightened by means of a cottle pin and
nut or a screw. Outside the centre tube we have a spiral spring, which extends
from the top of the seat tube downwards. To regulate the action of the seat tube
or pillar in the main down tube of the machine we insert a pin or screw, and on
the side of the seat pillar or tube we have a slot or slots, which allow for the up
or down action of the seat pillar. The action can be adjusted by means of a screw,
washer, and nut at the lower end of the seat pillar.

Improvements in Velocipedes and Attachments thereto.
WILLIAM GEORGE HARTNOLL, Builder, 65, High Street, Barnstaple, and JOHN
BEER JONES, Printer, 117, Boutport Street, Barnstaple, in the County of Devon, 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 has for its object the use of a connecting rod and cog wheels
instead of the use of a chain for the propelling of velocipedes.
In Fig. 1 "A" and "B" are the cog wheels, "C" is the connecting rod, "D"
the guide, and "<< E" the crank, and "F" the crank on the hub or axle of the
hindermost wheel of the machine.
We propose to use two cog wheels, one being attached to the driving axle of the
machine, the other to the framework just behind it, and geared into each other.
To the latter wheel, we attach a connecting rod by means of a pin or crank. This
connecting rod we attach to a crank or wheel on the hub or axle of the hindermost
wheel of the machine. To prevent the bending of the connecting rod, to the side
stay of the machine we affix vertical guides, with or without rollers.
The brake for this machine passes down through the upright part of the handle
bars and the ball head of the machine, and is worked by a crank handle or wheel.
Our invention consists of two tubes or a rod " "A" and tube "B," which work
into each other by means of an internal and external screw thread. The top rod
passes up through the centre of the top of the handle bars, and is worked by, a
crank handle "C" which applies the brake as shewn in Fig. 2.
The two tubes or rod and tube are guided at intervals by metal rings. A por-
tion of the lower end of the bottom rod is formed square in section, which fits
into a square socket and so prevents the brake from turning round. To the bottom
rod the brake shoe is attached. The top rod is prevented from working upwards
by a metal plate fastened on the top of the handle bars.
The seat pillar for this machine would have a double tube which is inserted in
the down stay of the machine. In the outside tube "A" we have a spiral
spring "B," which supports the inside tube "C." To guide the inside tube we
insert a detachable metal pin or screw "D" across the outside tube. Ou the
opposite sides of the inside tube we have two slots which allow for the up and down
action of the inside tube, as shewn in Fig. 3.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
1. The cog wheels working into each other in the position substantially as
described and shewn in the drawings.
2. A connecting rod substantially as described and shewn in the drawings.
3. The improved gearing as hereinbefore described and shewn in Fig. 1 of the
drawings annexed.
4. Two tubes or a rod and tube working into each other by means of an internal
and external screw thread.
5. The crank handle or wheel to work the brake.
6. The improved brake as hereinbefore described and shewn in Fig. 2 of the
drawings annexed.
7. The seat pillar with a double tube as hereinbefore described.
8. The improved spring seat pillar as herein before described and shewn in Fig. 3
of the drawings annexed.
