[Communicated from abroad by LACOMBE & Co., of Levallois-Perret, near Paris,
in the Republic of France, Manufacturers.]
Improved Means for Securing Terminals or Binding Screws to Plates
or Electrodes for Electric Batteries.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows :-
This invention is designed to provide improved means for securing terminals or
binding-screws to carbon plates or electrodes for electric batteries.
For this purpose, the plate or electrode is, according to the present invention,
made with a transverse hole or cavity therein to receive a nut, and with another
hole extending longitudinally from its upper surface to the said hole or cavity for
the nut. These holes are preferably formed in an enlargement or head at the
upper end of the carbon. Through the said longitudinal hole is passed the screw-
threaded stem of the terminal or binding screw, and upon this stem is screwed the
aforesaid nut. A lock-nut or back-nut is also provided upon the said screw-threaded
stem, and is adapted to be screwed tightly against the upper surface of the head or
enlargement of the plate or electrode, to secure the terminal or binding-screw firmly
thereto. The said terminal or binding-screw is constructed in any well-known or
suitable manner to facilitate the securing thereto of the wire or conductor.
This mode of connection affords, amongst others, the advantage that the terminal
or binding-screw, while it can be very rigidly secured to the plate or electrode, can
be readily removed and tested.

I, HENRY HARRIS Lake, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 is designed to provide improved means for securing terminals or
binding screws to carbon plates or electrodes for electric batteries.
For this purpose, the plate or electrode, is, according to the present invention,
made with a transverse hole or cavity therein to receive a nut, and with another
hole extending longitudinally from its upper surface to the said hole or cavity for
the nut. These holes are preferably formed in an enlargement or head at the
upper end of the carbon.
A
Through the said longitudinal hole is passed the screw-threaded stem of a
terminal or binding screw, and upon this stem is screwed the aforesaid nut.
lock-nut or back-nut is also provided upon the said screw-threaded stem, and is
adapted to be screwed tightly against the upper surface of the head or enlargement
of the plate or electrode to secure the terminal or binding-screw firmly thereto.

page_text: The said terminal or binding-screw is constructed in any suitable manner so that
the wire or conductor may be easily secured thereto.
In the accompanying drawings
Figure 1 is a front view of a battery carbon provided with one of my improved
terminals.
Figure 2 is a side view partly sectional of the same.
a is the transverse hole or cavity made in the head or enlargement 6 of the plate-
or electrode c. A nut d into which the screw-threaded stem e screws is placed in
the said transverse hole the said screwed stem e passing through the longitudinal
hole fextending from the upper surface of the carbon head. g is a lock-nut or
back-nut which may be screwed down tightly upon the upper surface of the carbon
so as to clamp the binding screw thereto and is the terminal by which the wire or
conductor i is secured to the carbon plate.
This mode of connection affords, amongst others, the advantage that the terminal
or binding screw, while it can be very rigidly secured to the plate or electrode, can
be readily removed and tested.
'I wish it to be understood that I do not confine or restrict myself to the precise
details or arrangements hereinabove described and shewn as many variations may
be made therefrom without deviating from the main features of my invention.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :--
First. A carbon plate provided with a transverse hole or cavity near its upper
end and with another hole extending longitudinally from its upper surface to the
aforesaid hole or cavity, substantially as and for the purpose specified.
Second. The improved means for securing terminals or binding screws to carbon
plates or electrodes for electric batteries, substantially as described with reference
to the accompanying drawings.
