IMPROVEMENTS IN VELOCIPEDES
Year: 1884

page_text: I, JOHN FERGUSON of the Hollies Vicarage Lane Bowdon in the County of Chester,
Schoolmaster do bereby declare the nature of my invention for IMPROVEMENTS IN
VELOCIPEDES to be as follows:-
From the framework of the machine-Tricycle for instance-I project a fork or
forks. Between or within the prongs of these forks as K & K in the accom-
panying sketch I arrange three circular friction plate wheels A-C & D with two
intermediary friction rubber wheels & ¹.
The lower wheel A is keyed by a slide key to the pedal crank shaft B The two
upper wheels C. & D are keyed somewhat similarly to a shaft E which carries the
driving wheel of the machine.
D is firmly keyed at a short distance from the prong K' near F¹ while C is
loosely keyed at the opposite end of the shaft E near to F. & capable of being slid
along the shaft E on its own slide key, by the arrangement of the nut n ou the
threaded portion of shaft E.
Between C A & D I arrange the two rubber wheels rr which revolve on shafts
or spindles g, g³.
These spindles are held in position by means of other two forks H H³ projecting
from the framework.
The arrangement of the friction plate wheels may be reversed-A being placed
on the Driving Wheel shaft and C & D on the pedal crank shaft if desired.
They may be constructed of wood or metal or other hard material while the
rubber wheels may be constructed of india rubber or composition, compressed
leather, cotton or other fibrous material.
The rubber wheels may also be shaped as balls revolving on a spindle or within
a socket if desired.
The object of the arrangement of the wheels is to produce motion in the Veloci-
pede in the following manner.
The contiguity of the wheels C. r. A. r¹ & D. is first regulated by the adjustment
of the nut n on the threaded portion of the shaft E.
The power applied to the pedal crank shaft B revolves the friction plate wheel A
-this motion actuates the rubber wheels r & r¹ to the right & left respectively
Through these rubber wheels the motion is transmitted to the friction plate
wheels C & D which being keyed to the Driving shaft E revolves the. wheel of the
machine.
Dated this first day of January 1884.

page_text: I, JOHN FERGUSON of the "Hollies" Vicarage Lane Bowdon in the County. of
Chester Schoolmaster do hereby declare the nature of my invention for IMPROVE-
MENTS IN VELOCIPEDES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
From the Frame work of the machine-tricycle for instance-I project a fork or
forks as K K¹.
Between or within the prongs of these forks I arrange three friction plate
wheels A. C & D with two intermediary friction rubber wheels r. r¹.
The lower wheel A is loosely keyed by a slide key to the pedal crank shaft. B.
The two upper wheels C & D are keyed some what similarly to the shaft E which
carries the driving wheel of the machine.
D is firmly keyed at a short distance from the prong K¹ at F" while C is loosely
keyed at the opposite end of the shaft E near to F and is capable of being slid along
the shaft E on its own slide key by the arrangement of the nut n. on the threaded
portion of the shaft E.
Between CA and D I arrange the two rubber wheels r. 21 which revolve on
shafts or spindles g. ġ¹.
These spindles are held in position by means of other two forks H. H projecting
from the frame work.
The arrangement of the friction plate wheels may be reversed-A being placed on
the driving wheel shaft and C & D on the pedal crank shaft if desired.
They may be made of wood faced or plain-of metal or other hard substances
while the intermediary wheels may be constructed of india-rubber-composition-
compressed leather, cotton or other fibrous material.
Or, vice versa. The friction plates may be faced with rubbers &c & the inter-
mediary wheels may be of a hard material or even of rubber &c.
The intermediary wheels may also be shaped as balls revolving 'on a spindle
or within a socket-if desired.
The object of the arrangement of the wheels is to produce motion in the machine
in the following manner:-
-
The contiguity of the wheels C. r Ar¹ D is first regulated by the adjustment of
the nut n on the threaded portion of the shaft E.
The power applied to the pedal crank shaft B revolves the friction plate wheel A
-this motion actuates the rubber wheels rr' to the right & left respectively.
Through these rubber wheels the motion is transmitted to the friction plate
wheels C & D which being keyed to the Driving Shaft E revolves the wheel of the
machine.
Further by means of a screw the spindles g g¹ may be raised or lowered at will
& while the machine is in motion and thus increase or decrease the speed. If the
mechanism be 'adjusted to both sides of a velocipede & the back bone be arranged as
in an ordinary "Humber" Tricycle the mechanism would serve to regulate speed
and to steer the machine also, as the revolutions of the two side wheels could be
alternately increased or decreased by the action of the screw adjustment to g g².

page_text: Having now particularly described and ascertained the nature of my said
invention & in what manner the same is to be performed, I declare that what
I claim is :-
A new combination of friction wheels such that one driving friction plate wheel
may actuate other two friction plate wheels by means of two smaller intermediary
wheels or balls-or vice versa-two friction plate wheels may actuate another
friction plate wheel by means of two smaller intermediary wheels or balls-and
thus give motion to the machine to which the mechanism may be attached.
Dated this 2nd day of October 1884.
