GEORGIA TERMINAL PUBLIER y Application filed December 1,y 1928. Serial No. 323,167.

This invention relates to terminal pullers for use in removing the terminals of storage batteries, and more particularly to a device of this character which provides a means for engaging the terminal to pull the same which,

the same time, engages the post to provide leverage for the pulling action and wherein the pulling element may remain substantially stationary during the pulling operation eX- ceptfor motions imparted thereto by the post engaging element. Y,

An important object of theinvention is to provide a construction such that the puller may be engaged with the terminal at one side thereof only if but one side is accessible, andii-both sides are accessible, may be engaged with both sides of this terminal, and in which one of the terminal engaging elements provided for use in the latter situation is so arranged that it may be moved to a position where it does not in any way interfere with the operation.

provide a device of this character which may be readily and cheaply produced, which may be durable and eiiicient in service, and agensituation where both jaws can be engaged with a terminal in solid lines, the dotted lines indicating the position of the auxiliary jaw when this condition does not obtain;

Figure 2 is a transverse sectional view through the terminal puller, a terminal being indicated in dotted lines.

Referring now more particularly to the drawings, the numerals 10 and 11 designate handle members, of which the handle member 10 is provided, adjacent its lower end, with an angular extension 12 to which the handle element 11 is pivoted adjacent its `a link 16. The pivot.v 17 connecting the preslother.

lower end, as indicated atlf` The pivotal i connection is intermediate the ends 'of the `angular extension and the lower end lof the handle element 11 has an angular foot 14 extending in the same general direction as 55 the free end of the angular extension. Pivoted to the angular extension is the lower end 'of a pressure bar 15, the upper end of which is connected with the handle member 11 by sure bar to the angular extension is engaged ina slot 18 formed in the angular extension and extending longitudinally thereof, so that the lower end of the pressure bar may be adjusted toward and away from the `handle member 11 and accordingly toward and away from the foot 14 to' permit use of the device with the terminals of various sizes and connections of ditlerentsizes. y

Above the link 16, the handle member has connectedthereto at 19the'upper end ofl anI y arm 2O which has at its freeend portion an A still further ob]ect of the invention is to angular foot 21 which, in one position of the arm, opposes the foot 1 4 of the handle member A11. 75 In the use of the apparatus, where the Ytervini'nal to be removed is so locatedthata jaw vcan only be engagedbeneath onefside kof the connector, the armv 2O isV swungjupwardly along'V thehandle memberand maybe heldin this position by grasping it simultaneously with the .handle member. By moving the handle members 10 and 11 toward one another, the lowerend of the pressureV bar 15 is brought into engagement with the upper' surface of the battery post P and application of pressure will result in upward pressure ,upon the connector C. By vibrating thepull while maintaining this pressure, jthe con- 0 nector may be readilyv removed. VVherebothY sides of the connector are accessible, the arm 2O is swung downwardly so that both feet 14 and 21 engage beneath the connectorand the handle' members aremoved toward one an- 95 Since the construction hereinbefore set' forth is capable of a `certain range o' change and modification without materially departing from the spirit of the invention, I Ydo not 100 limit myself to such specific structure except as hereinafter claimed. l

I claim 1. In a terminal puller, a handle member having at its lower end an angular foot, a

ysecond handle vmember having an angular extension, said angular extension being pivoted to the first named handle member above Y foot and in yspaced relation thereto and hav-V ing an end extending outwardly over and beyond the foot, a link'pivoted to the first named handle member above said extension and paralleling said extended end thereof, and a pressure bar .pivoted at its upper end to said link and at its lower end to the lsaid end of Y the extension, the connection of the pressure bar with the extension being adjustable longitudinally of the extension.

` In a termina-l puller, a handle member having at its lower end an angular foot, a second handle member having van angular extension, said angular yextension being pivoted tothe first named handle member above the foot'and lin spaced relation thereto and hav-V ing anend extending outwardly over and beyond the'rfoot, a link pivoted to the first named handle member above said extension andparalleling said extended end thereof, a pressure 'bai-'pivoted at its upper end to vsaid link and at'its lower end to the said end of the extension, and an arm pivoted to the first named f ce lhandle member above the link and having at its free endan angular foot which in one position of the arm aligns with the foot of the first namedrhandle member in spaced opposition thereto.

t. In a terminal puller, a handle member having at its lower end an angular foot, a

Vsecond handle member having -an angular extension, said angular extension'being ypivoted to the first named handle member above the foot and in spaced relation theretoand hav- .ing an end extending outwardly over and beyond the foot, a `link pivotedV to the first named handle member above said extension and .paralleling said extended end thereof, a pressurebar pivoted at its upper end to said link and at its lower end to the said end o-f the extension, and an arm pivoted to the first named handle Lmember above the link and having at its `free end anangular foot `which in one position of the arm ,aligns with the foot of the rst named handle member in spaced opposition thereto, the connection of the pressure bar with the. extension being adjustable longitudinally of the extension. In testimony whereof I hereunto aix my signature.
