Improvements in the Entire or Partial Propulsion of Velocipedes
and other Light Vehicles by Means of Electro-motors Worked
by Primary Batteries.
We JOHN SHERRIN and JOHN VAUGHAN SHERRIN both of Codrington Road
Ramsgate in the County of Kent Electrical Engineers do hereby declare the naturo
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:-
According to this invention we propel bicycles tricycles and other velocipedes and road
vehicles such for instance as bath chairs by means of electromotors worked by suitable
primary batteries by preference of the type described in the specification of John
Sherrin's Patent No. 15730 of 1887. In this primary galvanic battery the cells
containing the electrodes are arranged in a cylindrical or other box mounted so that
it can be turned over around its axis and provided with a fluid-tight lid forming a
receiver or receptacle for the exciting liquid or liquids when the box is turned upside
down for putting the battery out of action.
In the accompanying drawings we have illustrated a mode of carrying this invention
into effect Figure 1 being a perspective view of so much of a tricycle with one road
wheel removed as will show clearly the arrangement of the driving parts, and
Figure 2 a perspective back view of the vehicle.
A is the battery constructed as stated mounted axially in bearings at the ends of
arms or brackets B fixed permanently or detachably to the framing C of the vehicle.
E is an electromotor of the ordinary Gramme type which is fixed permanently or
detachably by framing D to the framing C of the vehicle. The form of framing for
supporting the battery and motor will vary according to the construction and form of
framing of the velocipede or other vehicle to be propelled according to our invention,
and according as the invention is applied to an already existing vehicle or as the
vehicle is designed in the first instance to be propelled according to our invention.
F is a tooth wheel or sprocket wheel fixed to the road wheel axle K, power being
communicated thereto by a chain H from the spindle G of the motor or we may
use endless metal band or other suitable band or cord, or tooth wheel or other gearing.
PRI

page_text: I is a cord attached to the circumference of the battery box and to a handle L which
is arranged convenient for the rider's hand.
The battery A as shown in the drawing is in the position for action, sending an
electric current by means of suitable connections (not shown) through the motor E.
To stop the action of the battery and consequently interrupt the propelling power of
the vehicle, the rider pulls the cord I by the handle L so as to turn over the battery
whereby the exciting liquid is run out of the cells and discharged into the cavity of
the box lid. To reestablish the current and start the vehicle the handle L is turned
the reverse way thus allowing the battery to assume its norimal position.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First. The application of a primary battery and an electromotor supplied with
current thereby to a tricycle or other road vehicle for the entire or partial propulsion
thereof.
Second. The combination with the driving axle or wheels of a volocipede of the
tooth wheel F, driving chain H therefrom to the spindle G of an electromotor E, a
primary battery, and electrical connections therefrom to the motor, the battery and
the motor being mounted in framing B D fixed on to the framing Cof the velocipede
substantially as described with reference to the drawings.
Third. In a velocipede or other vehicle propelled by primary battery and electro-
motor the primary battery A. mounted as described and shown, in combination with
the cord I and handle L for putting the battery in and out of action.
