An object of the invention is to provide a means
and method for removing and cleaning the ter
minal clamps of a storage battery whereby this
means swung aside preparatory to clasping the
tool over a battery terminal clamp.

‘
This is accomplished by the provision of an im
proved tool adapted to clasp a storage battery
terminal clamp and be operated by a simple
gentle movement to force the clamp from the bat
tery post and obviating the hammering or tap
ping usually necessary for this operation. Pref
erably the tool is adapted to grip and support the
the jaws embracingthe battery terminal clamp,
and the cam~operated plunger in position to sep
arate the battery post and the terminal clamp.

erator may conveniently hold the latter ñrmly to

In the form of the invention illustrated herein,
as exemplary thereof, the tool comprises a pair of
levers or handles, and jaws associated therewith
adapted to clasp the underside of the battery ter
minal clamp, while a plunger which is operated
by a cam-lever functions to force the battery post

the tool are made to grip the terminal clamp so
as to securely hold it after its removal, and the
cam-operated plunger is hinged so it may be
swung out of the way and permit a wire brush
or other suitable cleaning implement to be passed _,
through the post-receiving aperture of the ter- `
minal clamp to thoroughly clean the latter. The
terminal clamp may then be quickly released
from the tool by the operator merely releasing
his grasp on the levers or handles so that the

Referring to Figs. 1 and 2, the tool of the pres

end portions I5 and Iâ of the levers Ill' and II re

comparatively flat and lying substantially in the
the handles extend upwardly at an angle and
thus avoid interference with adjacent objects.
According to the present invention, the por
tions l5 and i6 of the levers are provided respec
tively with flat jaws I'I and I8 which extend lat
erally of the direction of movement of said por
tions, the ends of the jaws having inwardly ex
tending ñanges or claws I9 and 20 respectively.
Opposite the claws I S and 20, the jaws I'I and

holds a wire brush in position to be inserted in

are bent at A so that they may be horizontal while

The device and method as thus provided by the
invention makes the comparatively difficult task
of removing the terminal clamp easy and safe to
do. In the servicing of automobiles, the battery
is often neglected because of the diliiculty of
properly cleaning the terminals thereof.
