4 Claims. (Cl. 2985) The invention aims to provide an exceptionally terminal and the terminal post and there is simple and inexpensive, yet an easily operable therefore no danger of injuring the battery case, and eflicient tool for pulling battery terminals cells or plates. from terminal posts or performing similar work, In the preferred construction, the two levers 5 5 the tool being so constructed that its use will cross each other and are fulcrumed together at 5 place no strain upon the battery case, cells or their crossing point, and when this construction plates even though a terminal being pulled has is followed, the slots l must converge downbecome badly corroded, and therefore very wardly. These slots may be slightly curved as tenaciously connected with the terminal post. shown.

10 Wi h h f r oing in view, t n i n r While it is possible that the levers could be sides in the novel subject matter hereinafter deformed oth rwise than f th exact sha e herescrib d and claimed, ip n eing accomin shown, this shape is preferred and it will be pli h d y r f r n to th a mpany ng drawobserved that both of said levers are suitably ing. offset at IE to clear the screw I3. g- 1 is a d BleVatiOn partly in Section Show It is preferable that the cross head I2 consist 15 ing the '6001 in of a central collar I! through which the screw Fig. 2 is an edge view.
