PROVISIONAL
SPECIFICATION.
Improved Electric Battery.
I, DANIEL FITZPATRICK, of 67 St. Paul's Street, Leeds, Electrician, do hereby
declare the nature of this invention to be as follows
The object of my invention is to construct a battery which will be more powerful
for its size than the "Leclanchè," and give better results.
My improved battery is constructed with an inner fluted or corrugated hollow
cylinder of carbon, and an outer cylinder of zinc as ordinary.
Around the said carbon or inner cylinder are insulators or rings preferably made
of indiarubber.
For the better protection of the zinc from the carbon I employ a cap or cover
made of insulating material for the top of the battery.
Dated this 17th day of June 1891.

COMPLETE SPECIFICATION.
Improved Electric Battery.
I, DANIEL FITZPATRICK, of 67 St. Paul's Street, Leeds, Electrician, 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:-
The object of my invention is to construct a battery which will be more powerful
for its size than the "Leclanche," and give better results.
My improved battery is constructed with an inner, fluted or corrugated hollow
cylinder of carbon, and an outer cylinder of zinc as ordinary.
Around the said carbon or inner cylinder are insulators or rings preferably made
of indiarubber.
For the better protection of the zinc from the carbon I employ a cap or cover
made of insulating material for the top of the battery.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a sectional elevation of my improved battery.
Fig. 2, is a plan of Fig. 1.
Fig. 3, is an elevation of inner fluted or corrugated carbon cylinder.
Fig. 4, is a plan of underside of Fig. 3.
A is a glass vessel, B is a cylinder of zinc to which the negative zinc pole C is
attached by providing a notch D in such pole and soldering the pole onto the
cylinder B. E is a hollow cylinder of carbon having corrugations F upon its
external surface and a terminal G to which the positive wire is attached. H are
the insulators or rings (preferably of indiarubber) around the carbon cylinder E,
and which act as a means for keeping the carbon and zinc cylinders apart. J is the
cap for the better protection of the zinc from the carbon, and which is made of
insulating material.
For the exciting fluid, solutions such as are usually employed in "single fluid "
batteries may be used.
By sealing down the cap J the battery can be made into a
preferred or required.
"sealed" one if

page_text: 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. In electric batteries the employment of hollow carbon cylinders having
corrugations or ribs upon their external surfaces, such as shown and described.
2. In electric batteries the combination of hollow carbon cylinders, such as E,
and insulators or rings, such as H, (with or without caps or lids, such as J),
substantially as set forth.
3. The improved electric battery such as shown and described.
