Application September 30, 1933, Serial No. 691,708
This invention relates to a tool designed 'for use in pulling or removing battery terminals, or similar uses, the primary object of the invention being to provide a tool of this character '5 which will direct a true vertical pull on the battery terminal being removed, thereby insuring against the battery terminal or battery post being broken or damaged by a lateral strain being directed to the terminal, during the operation of removing the terminal.
Another object of the invention is to provide a tool of this character embodying a pair of pivoted jaws to engage the terminal, and a vertically movable plungerI engaging the battery post, the jaws and plunger being operated simultaneously by the action of the pivoted handle members of the tool.
With the foregoing and other objects in View, which will appear as the description proceeds,
the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed,
may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawing:
Figure 1 is a side elevational view of a battery terminal removing tool 4constructed in accordance with the invention and illustrating the tool as positioned on a battery terminal.
Figure 2 is an elevational view illustrating one edge of the tool.
Figure 3 is a sectional View taken on line 3 3 of Figure 1.
Referring to the drawing in detail, the tool comprises a yoke or body portion including spaced bars 5 having enlargements 6 extended therefrom, the enlargements being formed with openings for the reception of the pins 7, on which the handles 8 are mounted.
These handles 8 may be of any desired length, ,45 and as shown are formed with inwardly extended ears 9 that have elongated openings in which the pins 10 are mounted, the pins 10 providing supports for the rollers 11, that move Within the elongated openings 12 formed in the ears 9.
As shown, these pins 10 also extend through openings formed in the ears 13 that extend laterally from the plunger 14, which operates through the bearing sleeve 14', the plunger being of a length to extend an appreciable distance beyond the spaced bars 5 ofthe body portion.
The jaws of the tool are indicated 'by the reference character 15, and are pivotally `mounted between the bars 5. Pivot pins 16 60 provide the supports for the jaws 15 and support the jaws in such a way that free pivotal movement of the jaws will be permitted at'all7 times.
Elongated openings 17 are formed in the jaws l5, which elongated openings have inwardly extended portions 18, which openings accommodate the rollers 19 mounted on the pins'20, .that in turn are carried by the bars 21 that are secured to the plunger 14 at 22, so that movement of the plunger will result in a relative movement of the bars 21.
As the bars 21 are moved through the clongated openings 17 and through the inwardly extended portions 18 thereof, the jaws 15 swing outwardly in spaced relation with each other, but when the plunger 14 is moved in the opposite direction, the rollers 19 will move from the inwardly extended portions of the elongated 80 openings, to the main portions thereof, resulting in the jaws moving towards each other to engage an article by inserting the points of the jaws under the terminal to a predetermined distance controlled by slot 18. `35
In order that the jaws will better grip the battery terminal, the free ends oi the jaws are substantially wide as shown by Figure 2 of the drawing, thereby providing ample surface.
It might be further stated that the spaced bars 5 or body portion of the tool, are held in proper spaced relation with respect to each other, by means of the pins 23.
In the use of the tool, the tool is positioned l over a battery post and battery terminal, the jaws of the tool resting under the battery terminal, while the plunger 14 contacts with the end of the battery post.
When the handles 8 of the tool are movedI towards each other, it is obvious that pressure is directed to the battery post by the plunger 14, and that the jaws 15 are raised by such pressure, thereby causing a direct vertical pull on the battery terminal, removing the battery terminal, and eliminating any necessity of exerting lateral strain on the battery post, which usually results in the battery post becoming damaged or broken, rendering the same unt for further use.
Having thus described the invention what is claimed is:
1. A battery terminal removing tool comprising a yoke, a pair of pivoted handles on the yoke, a vertically movable plunger to which the handles are connected, laterally swinging jaws mounted on the yoke, means for transmitting movement or" the plunger to the jaws, and said jaws and plunger adapted to move simultaneously in opposite directions to remove a battery terminal under which the jaws are positioned, when the handles are moved towards each other.
2. A battery terminal removing tool comprising a pair of pivoted handles having inwardly extended ears, a vertically movable plunger to which the ears are pivotallyy connected, a yoke including spaced bars to which the handles are connected, and between which the plunger moves, a pair of jaws pivotally mounted between the bars of the yoke, means for transmitting movement of the plunger to the jaws to move the jaws laterally simultaneously with the movement of the plunger, when the handles are operated.
3. A battery terminal removing tool comprising a pair of handles having inwardly extended ears, a vertically movable plunger having laterally extended ears to which the ears of the handles are pivotally connected, a yoke to which the handles are pivotally connected, jaws pivotally connected to the yoke and adapted to engage under a battery terminaLsaid plunger adapted to engage the battery post, and said handle adapted to operate to move the plunger and jaws simultaneously in opposite directions.
4. A battery terminal removing tool comprising a plunger, a yoke, handles connected to the yoke and having inwardly extended ears connected with the plunger, jaws pivotally connected with the yoke, means for transmitting movement of the plunger to the jaws for moving the jaws laterally with respect to the plunger.
5, A battery terminal removing tool comprising a pair of handles having inwardly extended ears, a plunger pivotally connected to the ears, a body portion to which the handles are pivotally connected, jaws pivotally mounted on the body portion and having elongated openings formed with inwardly extended end portions, bars connected with the plunger, rollers mounted on the bars and operating in the elongated openings, said rollers moving into the inwardly extended portions of the elongated openings moving the jaws away from each other when the handles are moved outwardly, thereby releasing the jaws.
6. A battery terminal removing tool comprising a body portion, handles pivotally connected to the body portion, a slidable plunger adapted to engage a battery post, means for connecting the plunger and handles to operate the plunger when the handles move with respect to each other, swinging jaws mounted on the body portion, and means for transmitting movement of the plunger to the jaws to swing the jaws latlili erally as the plunger moves through the body.
