PROVISIONAL SPECIFICATION.
Improvements in or relating to the Charging of Electrical
Accumulators or Secondary Batteries.
I JOHN EVELYN LIARDET of 16 Hyde Park Gate, in the County of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the charging of electrical accumulators or batteries,
and is particularly applicable to recharging those used for lighting buildings, also
for driving and lighting electric launches or other vessels and railway trains or
other vehicles.
:
According to this invention I fix in any suitable position one or more suitably
formed fans or air motors, the spindle or shaft or shafts of each fan or motor
having a suitable wheel or wheels keyed thercon so as to gear with a wheel or
wheels on the shaft or shafts of a dynamo or dynamos, in order that as the fans or
air motors work, the dynamo or dynamos in connection therewith shall be worked
thereby, and supply current to accumulators or secondary batteries. The aforesaid
spindles or shafts fitted to said fans or motors I provide with ball bearings. I may
employ suitable reversing or governing gear.
It will be seen that the dynamos being connected with the accumulators, will
keep them charged automatically or at pleasure.

Improvements in or relating to the Charging of Electrical
Accumulators or Secondary Batteries.
I JOHN EVELYN LIARDET, of 16 Hyde Park Gate in the County of London,
Engineer, 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 :-
This invention relates to the charging of electrical accumulators or batteries
automatically, and is particularly applicable to recharging those used for lighting
buildings, also for driving and lighting electric launches or other vessels and railway
trains or other vehicles.
According to this invention 1 fix in any suitable position one or more suitably
formed fans or air motors, the spindle or shaft or shafts of each fan or motor
having a suitable wheel or wheels keyed thereon, so as to gear with a wheel or
wheels on the shaft or shafts of a dynamo or dynamos, in order that as the fans or
air motors work, the dynamo or dynamos in connection therewith shall be worked
thereby, and supply current to accumulators or secondary batteries. The aforesaid
spindles or shafts fitted to said fans or motors I provide with ball bearings.
I may employ suitable reversing or governing gear.
It will be seen that the dynamos being connected with the accumulators will
keep them charged automatically or at pleasure.

page_text: And in order that my said invention may be more clearly understood I will now
proceed to describe the same with reference to the drawings accompanying this
Specification in which
Fig. 1 shews profile, Fig. 2 deck plan and Fig. 3 midship section of
launch fitted with my improvements;
river
Fig. 4 shews plan of a launch having my invention applied thereto in a modified
form;
4
Figs. 5, 6, 7, 8, shew cross sections taken through the lines A B, CD, and E F;
Figs. 6 and 8 being alternative forms of midship sections ;
Figs. 9, 10 and 11 shew my invention as applied to a railway train.
a shews a river launch, bb shew air-motors or fans. These may be, of any
suitable form and construction. c shews vertical shaft, on which the fan or air-
motor is fixed. d shews bevel gearing fixed to shaft c and horizontal shaft e.
shews pulley keyed on the shaft e, g shews belt, passing over the pulley fand
the pulley h mounted on the dynamo shaft. ii shew accumulators connected up
with the dynamo k. shews electric motor worked by the accumulators i.
screw propeller shaft actuated by the motor 1. n shews awning over launch o frame
to hold the air-motor b. pp shew spaces for passengers.
m shew's
On Sheet 2 is shewn a modification of my invention as applied to the working of
launches, in which sheet Fig. 4 shews a plan of a launch, and Figs. 5, 6, 7, and 8
shew cross sections as above described. These are the forms which I prefer to use
in connection with my invention.
In this view the parts constituting my invention are shewn in dotted lines.
49 shew tubes running from bow to stern of the launch, rr shew Archimedean
screws, fitted in the tubes 7 g, the shafts z z of which are connected with the shafts
of the dynamos k k.
At Sheet 3 Figure 9 shews elevation of a railway carriage to be attached to a
train, to light the train throughout by electricity. Fig. 10 shews section through
the end of said carriage, Fig. 11 shews section through the end of a railway
carriage having the centre of its roof raised, as at s. In this case it will be seen
that I employ two air-motors r r. t shews a tunnel or passage formed on the top
of the carriage. shews an Archimedean screw having trumpet ends u u.
to shews
shaft on which the Archimedean screw r is mounted. This shaft is mounted. in
bearings (not shewn on the drawings). x shews pulley keyed on the shaft w.
y shews belt passing over pulley and the pulley keyed on the shaft of the
dynamo k. In Fig. 11 there are two air-motors rr pulleys and belts y y, by
which the power to work the dynamo is duplicated.
The action is as follows:-
With reference to Sheet 1, (supposing the accumulators to be charged on
starting) as the launch travels, the wind will work the air-motors bb, and revolve
the shafts e c, and by means of the bevel-gearing dd, pulleys off and belts gy
will work the dynamo k and thus keep the accumulators ii charged sufficiently
to keep the electric motor / working when required, instead of having to resort to
charging stations as is now the case.
With reference to Sheet 2 as the launch travels the wind will rush through the
tubes 79 and rotate the Archimedean screws rr, thus actuating the shafts of the
dynamos kk, to charge accumulators, as before described.
With reference to Sheet 3 the train travelling quickly through the air will cause
the wind to enter one of the trumpet ends u and pass out at the other end, and in
its transit will rotate the Archimedean screw r, shaft w and pulley, thus working
the shaft of the dynamo h, by means of the belt y, which will charge the accumu-
lators as before described, current from which may be utilised for lighting the
train throughout.
It will be seen on reference to Fig. 11, that the power to work the dynamo his
obtained from two Archimedean screws.
With reference to the lighting of buildings, or obtaining electrical motive power,
the action would be precisely the same as that before described, the power being

page_text: obtained by means of a wind-mill or other air-motor fixed or placed in such position
outside the building, that the wind shall readily actuate such motors, to work a
dynamo or dynamos to charge accumulators as before described.
If found desirable I may sometimes take my current direct from the dynamo,
instead of from the accumulators.
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. In improvements in or relating to the charging of electrical accumulators or
secondary batteries, the employment of air-motors so arranged and connected with
buildings, launches or other vessels, and railway trains that they shall actuate a
dynamo or dynamos, substantially as and for the purposes set forth.
2. In improvements in or connected with the charging of electrical accumulators
or secondary batteries, the combination of air-motors, dynamos, accumulators and
electric motors substantially as set forth with reference to Sheet 1 of the
accompanying drawings.
3. In improvements in or relating to the charging of electrical accumulators or
secondary batteries, the combination of air-motors, dynamos, accumulators and
electric motors substantially as set forth with reference to Sheet 2 of the
accompanying drawings.
4. In improvements in or relating to the charging of electrical accumulators or
secondary batteries, the combination of air-motors, dynamos, accumulators and
electric motors substantially as set forth with reference to Sheet 3 of the
accompanying drawings.
5. Improvements in or relating to the charging of electrical accumulators or
secondary batteries substantially as hereinbefore described and shewn on the
accompanying sheets of drawings.
