PROVISIONAL SPECIFICATION.
Improvements in and connected with Supports for Electrical
Batteries used on Vehicles and the like.
I, THOMAS FROGGATT, of 55 Thomas Street, Kennington Park, London, File
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention relates to supports for electrical batteries used upon vehicles or
where vibration is experienced to a considerable extent and has for its object the
construction of the battery supports in such a form as to prevent as far as possible
the communication of vibration from the vehicle or other vibrating support to the
battery.
It has been found that this vibration has a very destructive effect upon the
internal arrangements of the batteries, necessitating a very heavy expenditure for
repairs and renewals; and further as it is usual to connect the battery with the
circuit by means of spring connections of such a form that the circuit is continually
broken by the relative movement of the battery cells with the vehicle, the light or
supply of energy suffers considerably, from want of uniformity of transmission of
current through the circuit, and much annoyance is caused thereby.
This invention obviates all these disadvantages, and consists in the mounting of
the battery upon elastic or flexible supports carried by the vehicle or other device
upon which the batteries are situated, so arranged that when the battery is put in
place the connections are automatically made. To carry this invention into effect,
at each end of the battery box or case, metal supports are firmly fixed which are
made in the form of an inverted gutter or with an edge adapted to engage with a
support to prevent any large amount of lateral displacement. These supports are
electrically connected with the terminals of the battery. Upon the part of the vehicle,
or other device, carrying the battery, an elastic and insulated support is provided
upon which the supports at the ends of the battery engage by being hooked thereon.
The said elastic supports are formed of a strip of india-rubber or the like firmly
attached to the vehicle or other device and having a metal edge piece fixedly
attached to the india rubber or the like, the metal edge piece being adapted to
engage with the hook portion of the supports on the battery and to make electrical
connection therewith. The india rubber strip is arranged in such a way as to have
a considerable amount of elasticity, and to permit the battery to be elastically
supported with a considerable range of movement.
The insulated metal strips are connected to the circuits outside the battery.
When it is necessary as in secondary batteries to remove the batteries for
recharging, immediately the battery is lifted from the supports, the circuit is
broken, and upon replacing it, the circuit is automatically made.
The vibration from the vehicle is not communicated to the battery to any extent
but is absorbed by the elastic supports, the movement of the supports one on the
other, ensuring good contact being kept up between them.
The elastic support may be equivalently arranged on the battery instead of on
the vehicle if necessary.

I, THOMAS FROGGATT, of 55 Thomas Street, Kennington Park, London, File
Manufacturer, 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 supports for electrical batteries used upon vehicles, or
where vibration is experienced to a considerable extent; and has for its object the
construction of the battery supports in such a form as to prevent, as far as
possible, the communication of vibration from the vehicle or other vibrating
support to the battery.
It has been found that this vibration has a very destructive effect upon the
material arrangements of the batteries, necessitating a very heavy expenditure for
repairs, and renewals; and further, as it is usual to connect the battery with the
circuit by means of spring connections, of such a form that the circuit is continually
broken by the relative movement. cf the battery cells with the vehicle or other
support, the light or supply of energy suffers considerably, from want of uniformity
of transmission of current through the circuit, and much annoyance is caused
thereby. This invention has further for its object the obviation of all these
disadvantages, and consists in the mounting of the battery upon elastic or flexible
supports carried by the vehicle or other device upon which the batteries are
situated, so arranged that when the battery is put in place. the electrical connections
are automatically made at the same time.
In order that my invention may be the better understood, I will now proceed to
describe it in relation to the accompanying drawings, reference being bad to the
letters and figures marked thereon. Like letters refer to like parts in the various
figures.
Figure 1 is a sectional elevation of a battery supported within a box or case
according to my invention.
Figure 2 is a plan of the same the box being in the open position.
Figure 3 is an enlarged sectional view of the electrical connecting and supporting
device..
To carry my invention into effect, at each end of the battery box or case A for
containing the cells, I arrange metal supports B firmly affixed thereto, which are
made in the form of an inverted gutter, or with such an edge as will prevent any
large amount of lateral displacement relatively to the main support upon which
they rest.
These supports B are electrically connected respectively with the terminal
bars C to which the cells are connected. Upon any convenient part of the vehicle
or other device carrying the battery, or as shown in the drawing upon the interior
sides of an outer case D, I arrange elastic and insulated supporting pieces E, upon
which the supporting pieces B are engaged.
The elastic insulated supports E are formed of a piece of insulating flexible
material F such as india rubber or the like, which is firmly attached at one end to a
suitable metal clip F, which is fixedly attached to the box or case D; the other end of
the flexible material F being attached to a metal piece G with an upturned edge,
adapted to engage with the hook portion of the supporting piece B, so as to make
electrical connection therewith. The strips of flexible material Fare arranged in
such a way as to have a considerable amount of elasticity, and to permit the
battery to be elastically supported with a reasonable range of movement to take
off vibration. The insulated metal pieces G are connected by the wires H to a

page_text: connector J, to which the external leads for the transmission of electrical energy
are attached. I further support the pieces B by arranging a wooden fillet K to
take the weight and prevent the bending out of the hooked portion.
When it is necessary, as in secondary batteries, to recharge the same, immediately
the battery is lifted from the supports E, the circuit is broken; and upon replacing
it the circuit is automatically made.
The vibration from the vehicle is not communicated to the battery to any
serious extent, but is absorbed by the elastic supports, the movement of the
supports B and E, one to the other, ensure good contact being kept up
between them.
be equivalently
that in which
It is quite obvious that the arrangement of the parts may
effected by the converse disposition of the supporting device, viz.
the elastic support is put on the detachable battery-box or case A.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1st. In a support for electrical batteries, a connecting piece elastically mounted
upon, and insulated from, the part upon which it is mounted, in combination with
another connecting piece, adapted to make electrical connection with the elastically
mounted connecting piece, so as to absorb vibration, and prevent its transmission
from one to the other, substantially as described.
2nd. A supporting device for electrical batteries substantially as described and
illustrated in and by the accompanying drawings.
Dated this 4th day of February 1895.
