Improvements in the Application of Primary Batteries and Electro-
motors to Tricycles and other Velocipedes.
We, JOHN SHERRIN and JOHN VAUGHAN SHERRIN both of Codrington Road
Ramsgate in the County of Kent Electrical Engineers do hereby declare the nature
of this invention to be as follows:-
This invention refers to the application of primary batteries and electromotors to
tricycles and other velocipedes for the entire or partial propulsion of same. The
batteries are by preference of the construction described in the Specification of our
Patent No. 13473 of 1888 and the electromotor by preference of the construction
described in the Specification of our Patent No. 2666 of 1888; as by this combina-
tion we ensure efficiency and economy.
In one form we arrange the batteries, the motor and the driving gear on a separate
one or two wheeled carriage or trolly which is or may be detachable from the tricycle
or other velocipede and by preference connected to the rear of it, the batteries resting
on or in a spring supported frame. A rubber lined or other wheel rim on one of the
trolly wheels is by chain driven from a countershaft arranged under the batteries at
or near the front end of same this countershaft being driven by chain or tooth wheel
gearing from the motor shaft which is also under the batteries towards the rear end
of same.
Or the trolly containing the batteries and the motor shaft and counter
shaft (if not driven direct) is so arranged that a chain from a pulley on the counter-
shaft transmits motion to a rubber lined or other wheel rim on the tricycle proper.
The rest of the tricycle needs but little alteration in order to adapt it to be wholly
or partially propelled by the motor and batteries on the detachable trolly. These
trollies are also applicable as an attachment to ordinary bicycles, the hind wheel being
removed, and to safety bicycles and Otto bicycles.
When applying the batteries and motor to a tricycle of the Starley Coventry
chair type we suspend, the batteries elastically from the framing behind the chair, the
motor shaft being arranged under the seat and a countershaft below it and more to
the front. If the motor power is to be merely an auxiliary to the pedalling the
pedal crank would be under the chair, the latter having the lower part cut away, or
a seat of any suitable forin may be substituted a clutch being provided and by
preference also a switch for varying the auxiliary power so that the machine may
be propelled as desired. This machine we also adapt to take two persons side by
side.
Instead, of a single backbone frame we may use a double frame.
As applied to a tricycle of the Cheylesmore Club type the batteries are arranged
behind the seat and the motor and countershaft' below the same, this construction
may also be arranged either for partial or entire electric propulsion.
The form of tricycle, shewn in Figure 2 of our patent Specification No. 5390
of 1888 we 'modify by arranging the motor above the batteries, the latter being
made to slide out behind and a chain from a sprocket wheel on the motor shaft trans-
mitting motion to a rubber lined or other wheel rim on one of the road wheels. Or
we place the motor close to the road wheel axle or on a sleeve thereon and provide
a countershaft above the batteries. A similar arrangement is applicable to a
Marlboro Club or Ripley tricycle type of machine.
+
In a rear steerer of the Marriott and Cooper form of transit carrier we make the
batteries take the place of the basket and arrange the motor below it and the
countershaft further behind.
We adapt the socalled Club Carrier of the Coventry Machinists Company or
similar type to our purpose by making the batteries take the place of the basket and
arranging the motor and countershaft below the same.

page_text: Instead of using countershaft gearing we may drive directly from the motor with
chain or rubber cord or worm wheel or other gear and sometimes provide two speed
gear so as to admit of hill climbing at a suitable slow speed and running at full
speed on a level road.

COMPLETE SPECIFICATION.
Improvements in the Application of Primary Batteries and Electro-
motors to Tricycles and other Velocipedes.
We, JOHN SHERRIN and JOHN VAUGHAN SHERRIN both of Codrington Road
Ramsgate in the County of Kent Electrical Engineers 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:-
The
This invention refers to the application of primary batteries and electromotors to
tricycles and other velocipedes for the entire or partial propulsion of same.
batteries are by preference of the construction described in the specification of our
patent No. 18473 of 1888 and the electromotor by preference of the construction
described in the specification of our patent No. 2666 of 1888 and in John Vaughan
Sherrin's patent application No. 4767 of 1890 as by this combination we ensure
efficiency and economy.
In one form shown in side view Figure 1 and plan Figure 2 we arrange the
battery M the motor N and the driving gear on a separate one- or two-wheeled
carriage or trolly X which is or may be detachable from the tricycle or other
velocipede and by preference connected to the rear of it the battery M resting on
springs M¹ or in a spring supported frame. The battery may in this and other forms
to be described be suspended by springs which are mounted in standards which
project from the top of the enclosing frame M². A rubber lined or other wheel
rim R on one of the trolly wheels is by chain driven from a pulley O on a counter-
shaft L arranged under the battery M at or near the front end of same this
countershaft being driven by chain K and sprocket wheels L and 'I (or by tooth
wheel gearing) from the motor shaft which is also under the battery towards the
rear end of same.
Or as shown in the side view Figure 3 and plan Figure 4 where X is the trolly
containing the battery M the shaft of the motor N drives direct by a chain to a
rubber lined or other wheel rim Ron the tricycle proper. The rest of the tricycle
needs but little alteration in order to adapt it to be wholly or partially propelled by
the motor which is mounted on an extension B from the upright limb A of the
frame. These trollies are also applicable as an attachment to ordinary bicycles, the
hind wheel being removed and to safety bicycles add Otto bicycles.
When applying the battery and motor to a tricycle of the Starley Coventry chair
type as shewn in the side view Figure 5 and plan Figure 6 we suspend the battery M
elastically by springs M' from a double extension B behind the chair Y of the
framing A the motor shaft being arranged under the seat and a countershaft below
it and more to the front, the motion being transmitted by chain and sprocket
wheels L and L. If the motor power is to be merely an auxiliary to the pedalling
the pedal crank would be under the chair, the latter having the lower part cut away
or a seat of any suitable form may be substituted, a clutch being provided by
preference also a switch for varying the auxiliary power so that the machine
may be propelled as desired. This machine we also adapt to take two persons
side by side.
As applied to a tricycle of the Cheylesmore Club type shewn in the side view
figure 7 and plan figure 8 the battery is arranged behind the seat supported by
bottom springs M₁ or suspended in springs as previously described, and the motor N
and counter-shaft L are below the same mounted under the framing A this construction

page_text: may also by providing suitable clutches be arranged either for partial or entire
electric propulsion.
The form of tricycle shown in Figure 2 of our patent specification No. 5,390
of 1888 we modify as shewn in the side view figure 9 and plan figure 10 by arranging
the motor N above the battery being mounted on back extension B of the framing A.
The battery is made to slide out behind. A chain from a sprocket wheel I on the
motor shaft transmitting motion to a rubber lined or other wheel rim R on one of
the road wheels. Or we place the motor close to the road wheel axle or on a sleeve
thereon and provide a countershaft above the battery. A similar arrangement is
applicable to a Marlboro' Club or Ripley tricycle type of machine.
In a rear steerer of the Marriott and Cooper form of transit carrier, as shown in
the side view figure 11 and plan figure 12, we make the battery M. take the place
of the basket and arrange the motor below it and the counter-shaft if used further
behind. As here shewn the sprocket wheel I on the motor shaft, transmits motion
by chain direct to a pulley R on the wheel axle.
We adapt the so-called Club Carrier of the Coventry Machinists Company or
similar type to our purpose, as shewn in the side view figure 13 and plan figure 14
by making the battery M take the place of the basket and arranging the motor N
and the countershaft if used below the same. As here shewn the motor is mounted
under the framing which carries the battery.
Instead of using countershaft gearing we may as in the last two examples drive
directly from the motor with chain or rubber cord or worm wheel or other gear and
sometimes provide two speed gear so as to admit of hill climbing at a suitable slow
speed and running at full speed on a level road.
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.
The several combinations or arrangements of primary battery, electro motor and
driving gear in velocipedes substantially as shewn in the drawings and described
for adapting the various described forms of velocipedes to be driven by electricity.
