Year: 1885

page_text: I WILLIAM HENRY DUNKLEY of Jamaica Row Birmingham in the County of
Warwick Perambulator and Carriage Manufacturer do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN VELOCIPEDES OF THE KIND CALLED
TRICYCLE HORSES to be as follows:-
"
My invention consists in constructing and arranging the parts of tricycle horses
in the manner hereinafter described.
I arrange the axle of the driving wheels under the cheat or front of the model
horse the said axle having the driving cranks and pedals and working in bearings
carried by a bracket or brackets depending from the chest or front underside of the
body of the model horse.
The steering handle is situated over the neck of the horse at about the middle of
the neck and the vertical shaft to the top of which the handle is fixed passes down
through the body of the horse its lower end projecting from the body and having
an arm connected by a connecting rod to the arm at the head of the fork carrying
the steering wheel. The head of the fork is carried by and works in a bearing
carried by a bracket fixed on the rear underside of the horse. The arms of the
steering shaft and the steering wheel fork are turned in opposite directions and the
connecting rod connecting them crosses a vertical plane passing longitudinally
through the middle of the body of the horse.
•
Where for any reason the rotating motion of the cranks is objected to I adopt a
driving mechanism in which the foot of the rider in driving moves up and down
nearly in a vertical line. This mechanism consists of a rod jointed near its middle.
This rod is at one end jointed to a fixed point at the rear part of the horse's side.
The other end is jointed to the crank and the pedal is fixed to the middle joint of
the jointed rod. One of the jointed rods described is situated on each side of the
horse. In using the mechanism described the pressure of the foot causes the two
parts of the jointed rod to incline to each other at an obtuse angle the angle
becoming less as the foot descends and being at a minimum when the foot is at its
lowest position. When the foot is at its highest position the two parts of the
jointed rod are in the same line or nearly so. By this action the extreme ends of
the jointed rod are made alternately to approach to and recede from one another
and the rear end of the rod working on a fixed support the whole of the lengthening
and shortening of the distance between the ends of the rods is made to operate
upon the cranks.

page_text: I WILLIAM HENRY DUNKLEY of Jamaica Road Birmingham in the County of
Warwick, Perambulator and Carriage Manufacturer, do hereby declare the nature
of the said Invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
My invention consists in constructing and arranging the parts of tricycle horses
in the manner hereinafter described.
I arrange the axle of the driving wheels under the chest or front of the model
horse, the said axle having the driving cranks and pedals and working in bearings
carried by a bracket or brackets depending from the chest or front underside of the
body of the model horse.
The steering handle is situated over the neck of the horse at about the middle
of the neck and the vertical shaft to the top of which the handle is fixed passes
down through the body of the horse its lower end projecting from the body and
having an arm connected by a connecting rod to the arm at the head of the fork
carrying the steering wheel. The head of the fork is carried by and works in a
bearing carried by a bracket fixed on the rear underside of the horse. The arms
of the steering shaft and the steering wheel fork, are turned in the same direction
and the connecting rod connecting them crosses a vertical plane passing longi-
tudinally through the middle of the body of the horse.
Where for any reason the rotating motion of the cranks is objected to I adopt a
driving mechanism in which the foot of the rider moves up and down nearly in
a vertical line. This mechanism consists of a rod jointed near its middle.
This
rod is at one end jointed to a fixed point at the rear part of the horse's side. The
'other end is jointed to the crank and the pedal is fixed to the middle joint of the
jointed rod. One of the jointed rods described is situated on each side of the
horse. In using the mechanism described the pressure of the foot causes the two
parts of the jointed rod to incline to each other at an obtuse angle, the angle
becoming less as the foot descends and being at a minimum when the foot is at its
lowest position. When the foot is at its highest position, the two parts of the
jointed rod are in the same line or nearly so. By this action the extreme ends of
the jointed rod are made alternately to approach to and recede from one another
and the rear end of the rod working on a fixed support the whole of the lengthening
and shortening of the distance between the ends of the rods is made to operate
upon the cranks,
Figure 1 of the accompanying Drawing represents in side elevation a tricycle
horse containing my improvements; Figure 2 is a plan of the same the horse being
removed and Figure 3 is an end elevation of a portion of the same.
a is the axle of the driving wheels b, b, the said axle being situated under the
chest or front of the model horse c and working in bearings d², d' carried by the
fixed brackets d, d depending from the underside of the body of the model horse c.
The brackets d, d and a portion of the crank axle are shown in end elevation in

page_text: Figure 3. The said crank axle a of the driving wheels b, b may either be driven
by the feet of the rider acting directly on the pedals on the driving cranks e, e, or
the said cranks may be worked by the lever or jointed rod arrangement repre-
sented in the Drawing. The said jointed rods are marked respectively h, ha
and h, h² and are situated on opposite sides of the model horse c. Each jointed
rod is jointed at its middle by the cross pin g and to the said pin g the pedal fis
connected. The outer end of the part h³ of each jointed rod is jointed at h³ to the
leg of the horse and the outer end of the part h of each jointed rod is hooked or
otherwise connected to the crank e on the crank shaft a as seen in the Drawing.
The pressure of the foot of the rider upon the pedal f causes the two parts h, h³ of
the jointed rod to incline to each other at an obtuse angle as seen in the lower
jointed rod Figure 1 and thereby virtually to shorten the said jointed rod.
When the foot of the rider is at its highest position the two parts h, h³ of the
jointed rod are nearly in the same line as seen in the higher jointed rod in Figure 1
and the said rod is nearly at its extreme length.
By this construction of parts the foot of the rider in driving the tricycle horse
moves up and down nearly in a vertical line, the inner or extreme ends of the
jointed rods at the middle joints 9, 9 being made alternately to approach to and
recede from one another.
I will now describe the steering mechanism is the steering handle situated
over the neck of the model horse c the said steering handle i being fixed at the top
of the vertical shaft k the said shaft passing down through the body of the horse
and working in the brackets d, d. On the lower end of the vertical shaft k is a
crank or arm which is jointed to the horizontal connecting rod m and the latter is
jointed to the crank or arm n at the top of the fork p carrying the steering wheel q.
The head of the fork p is carried by and works in the bearing p* on the horizontal
bracket fixed at the rear end of the horse.
By moving the steering handle i in one or other direction, a corresponding
motion is given to the steering wheel a through the shaft k, crank l, rod m aud
crank n and the steering of the tricycle horse thereby effected.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I claim
as my invention of "Improvements in velocipedes of the kind called tricycle
horses"
First. The construction and combination of parts hereinbefore described and
illustrated in the accompanying Drawing for driving the crank axles of tricycle
horses, whereby the foot of the rider in driving moves up and down nearly in a
vertical line.
Secondly. The construction and combination of parts herein before described
and illustrated in the accompanying Drawing for steering the bind steering wheel
of tricycle horses,
