PROVISIONAL SPECIFICATION.
An Improved Form of Electrode for Galvanic or Secondary Batteries.
I, EDWARD WILLIAM BONSON, of 54, Bellefields Road, Brixton, London, S.W.,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
I use strips, ribbons, leaves or foliations (hereinafter referred to inclusively by
the term "foliations") of lead of any thickness, section, length or shape suitable
for the purpose, either plain, corrugated, scored or otherwise shaped, for the active
material in my new form of electrode. The foliations I arrange together like
the teeth of an ordinary comb and attach, connect or fuse one end of such foliations
to or into a rib or connecting bar, as in the case of the back of an ordinary comb.
For the material forming the rib or back I use lead, any alloy of lead suitable, or
lead or alloy of lead cored with other suitable material, but advantageously
antimonious lead. The combination of these foliations and rib or back I may
herein term a "comb." I may form such combs by casting or stamping the
arrangement of foliations and ribs in one piece, or otherwise, and I may construct
such combs with foliations on each side of the rib, like the arrangement of an
ordinary double toothed comb.
Having constructed such combs I arrange one or a series of them in a framing
or connect them up into a series by connecting pieces or bars at any convenient
point of the comb. The framing or such may be of any suitable material either
lead, an alloy of lead, or lead with a core of other conducting or of any non-con-
ducting material, or of any non-conducting material that will withstand the action
of the electrolyte used, cored with a conducting material. The rib or back of the
combs may be suspended in, connected or affixed to, or fused into the conducting
material of the framing or connecting pieces, or otherwise to form proper contact
with the conductors to an outside circuit. The arrangement of combs & framing
or connecting pieces may be cast or stamped or otherwise formed in one piece.
Such an arrangement of combs and framing constitutes my improved form of
electrode. The ribs or backing of the combs may be vertical, horizontal or
diagonal in relation to the shape of the electrode. In the case of my employing
only one or a small number of combs, or any such an arrangement with foliations
of extra length to form an electrode, I may form a rib or numbers of ribs or series
of connecting pieces or fins through or at any point along the length of
the foliations, connected to framing or otherwise, these ribs, connectors or fins
being of any suitable material or combination of materials as previously mentioned.
In order to render a battery constructed on my "comb" principle as light as
possible for traction and portative purposes I may suspend or carry the combs
as described by placing the ends of same in or through slots, perforations or the
like in a carrying frame of non-conducting material, connecting the combs up as
required either on the inside or outside of this carrying frame. The connecting
pieces may be in the form of strips soldered or otherwise attached to the end of
combs or I may form in the non-conducting material of the carrying frame

page_text: grooves into which the ends of the combs jut and into which I may run metal to
effect connexion between the combs forming an electrode.

An Improved Form of Electrode for Galvanic or Secondary Batteries.
I, EDWARD WILLIAM BONSON, of 72, Beaufort Road, Birmingham, Electrical
Engineer (late of 54, Bellefields Road, Brixton, London, S.W.), 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:-

I use strips, ribbons, leaves or foliations (hereinafter referred to inclusively
by the term foliations") of lead either plain corrugated, scored, or otherwise shaped
but advantageously shaped as Fig. 1 in accompanying drawing. The foliations
I arrange together like the teeth of an ordinary hair comb and attach connect or
fuse one end of such foliations to or into a rib or connecting bar, represented by
the back of an ordinary comb. For the material forming the rib or back I
use lead or lead cored with other material or advantageously, antimonious lead.
The combination of these foliations and rib or back, as shewn in Fig. 2, I may
herein term a "comb." I may form such combs by casting or stamping the
arrangement of foliations and rib in one piece and may construct such combs
with foliations on both sides of the rib like the arrangement of an ordinary double-
toothed comb. Having constructed such combs I arrange one or more of them in a
framing or with a series of connecting pieces or bars at any convenient point but
advantageously at each end of the combs, as shewn by Fig. 3. The connecting
framing or such may be of lead an alloy of lead or of other conducting material or
of any conducting or non-conducting material cored with a conducting material.
The rib or back of the combs may be connected or affixed by any means, but
advantageously fused into the conducting material of the framing of connecting
pieces so as to form proper contact with the conductors to an outside electric circuit
as shewn in Fig. 3.
The arrangement of combs and connecting framing may be cast, stamped or
otherwise formed in one piece. Such an arrangement of combs and connecting
framing constitutes my improved form of electrode for batteries and a general
view of such a form of electrode is shewn in Fig. 4. The ribs may be vertical,
horizontal or diagonal in relation to the shape of the electrode.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The construction of electrodes for galvanic or secondary batteries in the form
of a series of combs and connecting pieces substantially in the manner described.
2. The form of "foliation or such as shewn in Fig. 1.
Dated this 28th day of October 1897.
