PROVISIONAL SPECIFICATION.
Improvements relating to the Connections of Battery Receptacles
employed in Electrically Propelled Vehicles.
I FRANK KING of 4 Great Winchester Street in the City of London Electrical
Engineer do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in connection with the carrying and
connecting of secondary batteries in self contained electrically propelled vehicles
and has for its object to provide means whereby the case or receptacle containing
the source of electricity which is preferably an electric secondary battery or
batteries or accumulator can be readily placed and retained in position and the
necessary electrical contacts are automatically made in the act of so placing the
receptacle containing the said battery and the said contacts are maintained in an
effective condition.
'
According to my invention I attach to the underside of the case or receptacle in
which the secondary battery or batteries is or are carried runners of grooved or
other suitable section which take into and run upon rails fixed to the bottom of
the vehicle or to the battery support or shelf, and of such section as to fit into
the said runners and give the greatest possible contact surface.
The runners are connected with the terminals of the secondary batteries by
means of conductors passing through or alongside of the battery case or receptacle
and by means of the contact secured with the rails, which with the runners are
both made of suitable conducting metal, the current is conducted to any desired
place on the vehicle for instance to the motor or to lamps.
The vibration of the vehicle when in motion will cause the runners affixed to
the case or receptacle to slide and rub on their respective supporting rails and the
said connections will thus be automatically kept clean while by reason of the
runners taking onto the rails the displacement of the case or receptacle containing
the battery or batteries in a transverse direction will be prevented.
I may reverse the order of such runners and rails putting the runners on the
bottom of the vehicle or of the battery support or shelf and the rails on the
underside of the battery receptacle or case.
By breaking the metallic continuity of the runners and rails I may obtain any
desired arrangement of the connections and to secure smoothness in working where
such breaks occur I may supply the place of the metal with an insulating wear
resisting material.

I, FRANK KING of 4 Great Winchester Street in the City of London Electrical
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 :-
My invention relates to improvements in connection with the carrying and
connecting of secondary batteries in self contained electrically propelled vehicles
and has for its object to provide means whereby the case or receptacle containing
the source of electricity which is preferably an electric secondary battery or
batteries or accumulator can be readily placed and retained in position and the
Decessary electrical contacts are automatically made in the act of so placing the
receptacle containing the said battery and the said contacts are maintained in an
effective condition.
According to my invention I attach to the underside of the case or receptacle in
which the secondary battery or batteries is or are carried runners of grooved or
other suitable section which take into and run upon rails fixed to the bottom of the
vehicle or to the battery support or shelf, and of such section as to fit into the said
runners and give the greatest possible contact surface.
The runners are connected with the terminals of the secondary batteries by
means of conductors passing through or alongside of the battery case or receptacle
and by means of the contact secured with the rails, which with the runners are
both made of suitable conducting metal, the current is conducted to any desired
place on the vehicle for instance to the motor or to lamps.
The vibration of the vehicle when in motion will cause the runners affixed to the
case or receptacle to slide and rub on their respective supporting rails and the said
connections will thus be automatically kept clean while by reason of the runners
taking onto the rails the displacement of the case or receptacle containing the
battery or batteries in a transverse direction will be prevented.
I may reverse the order of such runners and rails putting the runners on the
bottom of the vehicle or of the battery support or shelf and the rails on the
underside of the battery receptacle or case.
By breaking the metallic continuity of the runners and rails I may obtain any
desired arrangement of the connections and to secure smoothness in working where
such breaks occur may supply the place of the metal with an insulating wear
resisting material.
In order that my invention may be clearly understood I refer to the accompanying
drawings representing arrangements according to my invention.
Figure 1 is a part sectional elevation and Figure 2 is a plan of the floor of parts
of the receptacle and trough. Figure 3 is a sectional elevation at right angles to
Figure 1. The trough C is supported on the runners A and rails B. The rails B
are fixed to the floor of the receptacle for containing the battery as shewn at K.
The runners A are shewn attached to the connecting bar D which as shewn in
Figure 1 is the means of connecting the pole of the battery H to the said
runner A.
B' is the insulating wear resisting material such as slate, ebouite, hard wood or
the like by which the continuity of the rails B is maintained.
Figure 4 shews the runners A and rails B reversed the runners A being on the
receptacle and the rails B being on the trough.
Figure 5 shews diagrammatically the arrangements of the rails B on the floor K,
shewing the connection between the terminals D of the batteries in their respective

are in contact with the rails. The lines 1 to 8 indicate the permanent connections
from the rails to the switch or similar device which may be used to connect up the
batteries in the desired series to the driving or other motor or motors or other
devices.
inven-
Having now particularly described and ascertained the nature of my
tion and in what manner the same is to be performed I declare that what I
claim is.-
In, or for, electrically propelled vehicles an arrangement of rails and runners for
both connecting together electrically and carrying or supporting in the desired
position a secondary battery or secondary batteries substantially as hereinbefore.
described and illustrated by the accompanying drawings.
