Year: 1896

page_text: I, JOHN MILES MOFFAT, of 2 Heath Villas, Cargill Road Earlsfield, in the County
of Surrey, Electrical Engineer, do hereby declare the nature of this invention to
be as follows:
My invention relates to improvements in the cells or boxes of electric batteries,
and its main object is to improve the construction of battery-boxes such as I have
described in the Specification of former Letters Patent granted to me and dated
30th May 1894, No. 10463.
My present invention comprises an improved method of sealing the connections
between the conducting wires and the terminals by means of cement or other sealing
material poured into one or more sealing boxes or cells formed on the exterior of
the battery-box or cell and having the terminals or binding-screws fixed therein.
I make the said sealing box or boxes in such a manner that, after the connections
with the terminals have been made, cement or other suitable sealing material can
be poured into the said sealing box or boxes, and will surround and protect the
said connections. This part of my said invention is applicable to batteries suel
as are described in my said former specification and also to batteries of other
construction in which it is desirable to seal the connections between the conducting
wires and the terminals.
With portable batteries in which the conducting wires are passed through the
lid, packing-nuts of indiarubber, glass or other suitable material have to be used,
to hold them in place on the lid, and difficulty is experienced in taking off the lid.
And with those batteries in which the conducting wires are led through the side
of the box, there is liability to creeping of the acid through the holes in the side
and along the terminals, with the result that loss of energy is caused.
By the use of my sealing box or boxes I obviate both of these inconveniences,
and am enabled to take off and replace the lid without disturbing the connections..
In some instances I connedt the said sealing box or boxes with a channel or.
channels in the battery-box or cell so that a tight joint will be formed between
the two compartments of the battery-box or cell, and also, if desired, between the,
box and the lid.
My said invention also comprises an improved form of construction of battery:
box of the kind or class described in my said former specification. I make the lid
of the battery-box with an internal diaphragm or cover for the compartment or
compartments of the box, having a sloping or inclined upper surface or surfaces
and having at the lower end of the said surface or surfaces a vent hole or tube;
and in the top of the lid above each compartment I form a small hole which is.
surrounded by an inwardly turned or curled lip, the hole or holes in the top of the
lid being not in the same vertical place as the vent hole of holes, and being pre-:
ferably central relatively, to the compartment or compartments. I lead the con-
ducting wires through the side of the body of the box, and connect thein 'to
suitable terminals preferably fixed in the ends, front or top of the sealing box of
boxes above mentioned.

page_text: I find it advantageous to make the lid with a channel or groove around its
interior, communicating with the said sealing box or boxes, and, in the case of a
cell having two compartments, I sometimes divide the lid into corresponding
compartments, and I also form a transverse channel or groove in the lid into
which the upper end of the partition in the box will extend when the lid is in
place on the box. And I form one or more holes or passages through the side of
the battery-box from the said channel or channels, so that, when the connections
to the terminals are made, the battery-box can be inverted and cement or other
sealing material poured into the sealing box or boxes, and the said sealing material
will then flow through the said passage or passages into the said channel or
channels. Or I fit india-rubber packing into the said channel or grooves to form a
tight joint between the lid and the box.
I sometimes provide the battery-box with an external sealing box at each end
thereof, and in this case, if desired, the terminal screws may also serve for
securing the lid on the box.

I, JOHN MILES MOFFAT, of 2 Heath Villas, Cargill Road Earlsfield, in the County
of Surrey, 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 the cells or boxes of electric batteries,
and its main object is to improve the construction of battery-boxes such as I have
described in the Specification of former Letters Patent granted to me and dated
30th May 1894, No. 10463.
My present invention comprises an improved method of sealing the connections
between the conducting wires and the terminals by means of cement or other sealing
material poured into one or more sealing boxes or cells formed on the exterior of
the battery-box or cell and having the terminals or binding-screws fixed therein.
I make the said sealing box or boxes in such a manner that, after the connections
with the terminals have been made, cement or other suitable sealing material can
be poured into the said sealing box or boxes, and will surround and protect the
said connections. This part of my said invention is applicable to batteries such
as are described in my said former specification and also to batteries of other
construction in which it is desirable to seal the connections between the conducting
wires and the terminals.
Figure 1 of the accompanying drawings is a longitudinal section, and Figure 2
is a transverse section of the upper part of a cell according to my invention,
Figure 3 is a side view. Figure 4 is a longitudinal section shewing a modification.
a is the cell or box which may be divided into two compartments by a
partition b. The lid has a floor c sloping both ways, and downwardly projecting
flanges and h having spaces d for cement between them and the walls and
partition. The upper part of the lid 9 provides a space into which vapour can
ascend through holes f and escape through openings g' which are not in vertical
line with the holes f. Such of the vapour as condenses flows down the slopes c,
and back through the holes f into the cell. At the side of the cell I provide a

page_text: sealing box which is independent of the lid and integral with the cell, and has
terminal screws e. Before putting on the lid g, all the electrical connections are
made to the plates in the cell and from them through holes a to the terminal
screws in the sealing box. The lid being then put on, the box is inverted and
suitable fused cement d is poured into the contact box, whence it finds its way
to the spaces d left to receive it, thus sealing the lid to the cell. Instead of filling
the spaces d under the lid with cement, they may be filled with caoutchouc or
other packing as shewn in Figure 4, the lid in this case being held down by bolts 7.
Instead of a single sealing box, several of these may be employed at the sides or
ends or both.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
In combination with an electric battery cell and its removable lid a sealing
box or several of these so arranged that before fixing the lid the electrical
connections can be made, substantially as described.
