page_text: I, CHARLES JARROTT, of 40, Holborn Viaduct, in the County of Middlesex,
Secretary, do hereby declare the nature of this invention to be as follows:-
My invention refers to the application of a motor to a cycle carrier and has for
its object the easy adaptation of the present form of cycle carrier to a motor
propelled one.
In place of the small wheel at the back of the cycle carrier, I place two wheels
on an axle with motor attached the mechanism being of the same description
as that in a De Dion motor tricycle. I attach this to the cycle carrier by means
of a socket head pivot or any other suitable arrangement and connect the said
axle and wheels by means of rods, levers or chains to the steering gear as at
present arranged and manipulated either by screw, rack and pinion, worm or
any other form of steering. Thus, the steering will be done by the two back
wheels to which the motor is attached.

I, CHARLES JARROTT, of 40, Holborn Viaduct, in the County of Middlesex,
Secretary, 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:-
My invention refers to the application of a motor to a cycle carrier and has for
its object the easy adaptation of the present form of cycle carrier to a motor
propelled one.
In place of the small wheel at the back of the cycle carrier, I place two wheels
on an axle with motor attached the mechanism being of the same description
as that in a De Dion motor tricycle. I attach this to the cycle carrier by means
of a socket head pivot or any other suitable arrangement and connect the said
axle and wheels by means of rods, levers or chains to the steering gear as at
present arranged and manipulated either by screw, rack and pinion, worm or
any other form of steering. Thus, the steering will be done by the two back
wheels to which the motor is attached.
In the acompanying drawings:-
Figure 1 is a perspective view of a carrier constructed according to one method
of carrying out my invention, and

page_text: Figure 2 is a perspective view of a modified method of carrying out the said
invention.
In the form of carrier shown in Figure 1, in which the rider sits in front of
his load, the carrier frame A is of the usual construction, being provided with
two front wheels B arranged to be driven by pedal and chain gear in the usual
manner, but the back wheel, which is commonly carried in a socket C is removed
and replaced by a pair of wheels C¹ mounted fast on a driving axle C. The
axle C is carried in suitable bearings on a fork C3, which is free to turn in
the socket C. A bracket D secured to any convenient part of the fork C³ carries
a motor D¹, preferably of the De Dion type. The bracket D may be attached
to the upper portion of the motor, and the lower portion or crank chamber of the
same may be provided with a bracket or bearing D² arranged to embrace the
driving shaft C². By this means the motor will be rigidly connected to the
fork C³, although it is obvious that the brackets, by which it is secured, may be
disposed otherwise than in the particular manner described.
The axle or driving shaft C2 carries the usual reducing gear wheel E, which is
A car-
preferably always in engagement with the pinion E of the motor.
burettor F may be placed in any convenient position upon the frame A of the
carrier to supply the motor with its necessary combustible charge.
The steering is effected by means of the usual handle G, which is connected
by any convenient means to the fork C³ of the driving wheels C¹; thus the
steering is effected in exactly the same manner, as in the ordinary tricycle
carrier, the axle C² being if necessary, provided with differential gearing.
The operation of the motor carrier is obvious:-
The motor is started by means of the ordinary pedal and chain gear with
which the carrier is provided, this gear being provided with the usual ratchet
or other mechanism by which the carrier when once started may be allowed to
overrun the pedal gear and for the control of the motor, levers may be arranged
on either side of the driver for cutting off the supply of carburretted mixture
to the motor, opening the exhaust valve, or performing any other operation
necessary for increasing or decreasing the speed of the motor.
"
Figure 2 shows the invention applied to the form of carrier in which the
driver sits behind his load being supported by a single steering wheel provided
with pedals and " crypto or other gear. In this case the motor D₁ and its
mechanism are mounted in front of the load, the motor being carried by a
bracket H secured to one of the cross, or transverse members of the frame A.
and the lower part or crank chamber of the motor D₁ may be further steadied
by the bottom longitudinal member of the frame A, which may be secured to it,
the same being braced by struts or ties A¹ connecting it to the upper part or
portion of the frame. The reducing gear wheel E of the motor may be mounted
upon the ordinary axle J of the road wheels J¹, the axle J being for this purpose
mounted in bearings Ja, and the wheels being operatively connected with it,
the carburettor F is carried by supports F1 from one of the transverse members
of the frame A, but may obviously be placed in any other convenient position,
if desired. The operation is the same as that described with reference to
Figure 1, the motor carrier being started by the ordinary pedal gearing with
which the rear wheel is provided as described above, and controlled by means
of taps or levers placed within convenient reach of the rider.
If preferred, the form of carburettor F shown in Figure 2 may be used in the
arrangement shown in Figure 1 or vice versa, and it is obvious that by removing
the body of the carrier, that is the part within which the load is placed, and
mounting in its place one or more seats, a light form of vehicle may readily be
constructed.
It will be understood that although Figure 2 is described as the conversion
of a carrier, ordinarily provided with a single rear steering and driving wheel
over which the seat of the rider is placed, into a motor carrier, if preferred a
carrier of the kind described in Figure 1 before conversion may be provided with

page_text: a rear driving and steering wheel having a seat above it, the motor and its
mechanism being mounted in the front between two non-steering wheels as
described with reference to Figure 2.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The conversion of a carrier having a single steering wheel into a motor
carrier by the application of a steering fork such as C3 carrying a pair of wheels
and a motor by which the said wheels are driven substantially as described.
2. The conversion of a carrier having a single steering wheel into a motor
carrier by substituting a motor and its appurtenances for the usual crank driving
mechanism of the two non-steering leading wheels and placing a saddle over the
back steering wheel and providing the wheel with gear whereby it may be used
for starting purposes.
3. The complete motor carrier substantially as described and illustrated in
Figure 1 or Figure 2 of the accompanying drawings.
