PROVISIONAL SPECIFICATION.
Improvements relating to the Terminals of Electric Batteries
and the like.
I, ALFRED CECIL WRIGHT, of the Firm of Wright & Rowland, New Bond
Street, in the City of Birmingham, Manufacturers, do hereby declare the nature
of this invention to be as follows:-
This invention consists of improvements relating to the terminals of electric
batteries and the like, my object being to so construct such terminals as to
permit of their being more effectually secured to the battery plates or other
like parts.
I produce battery terminals in accordance with my invention in the ordinary
screw or bolt form, but I make the portion of each terminal to be embedded in
the cap or upper portion of the battery plates of a flattened or rectangular shape
and with a circular or other flange or head at its outer extremity.
I preferably manufacture my improved terminal or binding bolts or screws from
brass or other metallic wire rods of a circular section, forming the flattened part
and the head or flange hereinbefore described in a machine such as is used for
the manufacture of rivets, employing with such machine properly shaped dies
or tools for the flattening and heading operation. To give an additional grip
or hold I raise snugs or projections from the faces of the flattened part of the
bolt, suitable and corresponding recesses being made in the dies or like tools
to form such projections.
The projecting or stalk end of the terminal is screwed for the ordinary clamping
or binding nut.
The flattened ends of the terminals are embedded in the caps or upper ends
of the battery plates in the ordinary manner, but by making the said terminals
of the form herein before described they obtain a firmer hold upon the plates and
are prevented from working loose and becoming detached when in service.
Dated this 1st day of August 1899.

of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:.
-
This invention consists of improvements relating to the terminals of electric
batteries and the like, my object being to construct the said articles at small
cost and in such a manner as to permit of their being more effectually secured to
the battery plates or other like parts.
to:
On the accompanying sheet of explanatory drawings to be hereinafter referred
-
Figure 1 is a side elevation and Figure 2 an end elevation showing one of my
improved electric battery terminals.
I produce battery terminals in accordance with my invention having projecting
or stalk like ends of the ordinary screw or bolt form, but I make the portion of
the terminal to be embedded in the cap or upper portion of the battery plates
of a flattened or rectangular shape and with a circular or other flange or head
at its outer extremity.
I preferably manufacture my improved terminal or binding bolts or screws
from brass or other metallic wire rods of a circular section, forming the flattened
part as A and the head or flange as B in a machine such as is used for the manu-
facture of rivets, employing with the machine properly shaped dies or tools for
the flattening and heading operation. To give an additional grip or hold I raise
snugs or projections as C from the faces of the flattened part of the bolt, suitable
and corresponding recesses being made in the dies or like tools to form such
projections. I sometimes also pierce or form a hole as 1 through the flattened
part for the same purpose.
The projecting or stalk end E of the terminal is screwed in the usual manner
for the ordinary clamping or binding nut by which the lead or conductor is
connected to the terminal.
The flattened ends of the terminals are embedded in the caps or upper ends
of the battery plates in the ordinary manner, but by making the
hereinbefore described they obtain
are prevented from working loose and becoming detached when in
firmer hold upon
a
said ends as
the plates and
service.
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
I claim is: -
1.Terminals or binding bolts or screws for electric batteries and for like
purposes, having a flattened end with a flanged extremity or head thereto, sub-
stantially as described and as illustrated.
2. The manufacture of terminal or binding bolts or screws having a flattened
and headed gripping end with snugs or projections therefrom substantially in
the manner described.
