page_text: I, DENYS MATHIEU, of Buckfast, Buckfastleigh in the County of Devonshire,
Catholic Priest, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in electrical batteries of the Leclanché
reaction, and has for object to increase the surface of the carbons used in such
batteries, thereby obtaining great power with comparatively but slight
resistance.
It consists in inserting a number of carbon pencils or cylinders between two
recessed or partly hollow carbon discs and clamping or otherwise securing these
discs together.
Preferably I arrange the carbon pencils concentrically with the discs, and connect
these latter by means of metallic or other suitable clamps coated with insulating
material and secured in place by convenient wedges or other suitable devices. The
lower ends of these clamps are continued below the lower disc so as to form supports
upon which the "cage" may stand when in position.
The upper carbon disc is furnished with an aperture and cover therefor, through
which aperture 1 insert a quantity of pulverised manganese and gas carbon which is
intended to fill the approximately cylindrical space between the carbon pencils and
the upper and lower discs.
I also attach a suitable terminal to the upper disc, and the whole "cage" is
placed within a zinc cylinder and insulated therefrom by the aforesaid clamps.
The zinc cylinder is also furnished with a terminal and the whole of the
battery is enclosed within a porcelain or other similar cell. Owing to the manner
in which the cage is supported upon the ends of the clamps within the cell, the
possibility of contact between the cage and the zinc cylinder through incrustation
is entirely avoided.
I, DENYS MATHIEU of Buckfast, Buckfastleigh in the County of Devonshire,
Catholic Priest, 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 improvements in electrical batteries of the Leclauché
reaction and has for object to increase the surface of the carbons used in

page_text: such batteries, thereby obtaining greater power with comparatively but slight
resistance.
It consists in inserting a number of carbon pencils or cylinders between two
recessed or hollow carbon discs, and clamping or otherwise securing these discs
together.
Upon the accompanying sheet of drawings illustrating my invention,-
Figure 1 represents an elevation of the "cage"
Figure 2 being a plan of the same;
Figure 3 is a plan view of a horizontal section through the cage, and
Figure 4 is an elevation of a suitable zinc cylinder used in the battery.
In carrying out my invention I arrange the carbon pencils a concentrically with
the discs bb, and connect these latter by means of three or more metallic or other
suitable clamps c coated with insulating material and secured in place by convenient
wedges d or other devices. The lower ends of these clamps c are continued
below the disc ' so as to form supports upon which the "cage" may stand when in
position.
The upper carbon disc 6 is furnished with an aperture and cover e therefor,
through which aperture or inlet I insert a quantity of pulverised manganese
peroxide and broken gas carbon which is intended to fill the approximately
cylindrical space between the carbon pencils and the upper and lower discs.
I also attach a suitable terminalf to the upper disc b, and the whole "cage" is
placed within an amalgamated zinc cylinder g such as shewn on Figure 4, and
insulated therefrom by the aforesaid clamps c. This zinc cylinder g is also
furnished with a terminal g', and the whole battery is enclosed within a porcelain
or other similar cell.
The porcelain, glass or other cell may then be partially filled with a suitable
solution of sal-ammoniac and on closing the circuit by connecting the terminals fg',
the battery will be set in action. Owing to the manner in which the cage is
supported upon the ends of the clamps within the cell, the possibility of contact
between the cage and the zinc cylinder through incrustation is entirely avoided.
It will be observed that the carbon pencils and discs are used in lieu of the
ordinary porous earthenware pot for containing the manganese and gas carbon, and
by this construction I am enabled to obtain great power with but slight
resistance.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
1 claim is :
1. In electrical batteries of the Leclanché reaction, a carbon pole composed of a
number of carbon pencils clamped between recessed carbon discs and containing
manganese and gas carbon in the approximately cylindrical space between such
pencils and discs, substantially as and for the purposes described.
2. In the carbon pole of an electrical battery as above described, the use of
clamps c operating as and for the purposes set forth.
