BATTERY-TERMINAL Lr'ran.

i Application illed July 17, 1926. Serial No. 12B-,113.

This invention relates to extractors and more particularly to an implement'especially designed for detaching the terminal from the post of a battery.

One object of the invention is to provide an implement of simple and compact construction by means of which a battery terminal which has become firmly attached to its post by corrosion or otherwise may be very easily detached.

Another object of the invention is to provide the tool with terminal and post engaging members, one of which is adapted to engage beneath the terminal and the other the upper end of the post so that, when pressure is applied to move one member toward the other, force will be exerted against the post and terminal and cause the terminal to slide longitudinally olf the post.

Another object of the invention is to provide a tool of this character which is strong and durable and capable of exerting great pressure against the terminal and battery ost. p The invention is illustrated in the accompanying drawing, wherein .Figure 1 is a perspective view of the device;

Fig. 2 is a view showing the lower por" tion of the device in side elevation and applied to a battery terminal and post-indicated by dotted lines.

The implement forming the subject-matter of this invention is constructed as shown in Fig. 1 and includes a standard 1 which is formed of strong metal and at its upper end carries a cross bar 2. The cross bar2 is rigid with the standard 1 and preferably formed integral therewith, although it may be separate and firmly secured thereto inany desired manner. The forward portion 3 of the cross bar 2 constitutes an arm disposed above the foot 4 at the lower end of the standard and the rear portion 5 of the cross bar constitutes a handle and is preferably circular in cross section so that it may be readily grasped. The foot 4 which is formed by bending the lower end portion of the standard is slotted, as shown at 6, in order to form forks or arms 7 adapted to extend beneath the battery terminal 8 at opposite sides of the post 9. These arms 7 preferably taper toward their inner side edges and free ends so that they may be readily forced beneath the battery terminal if it is badly corroded and have firm engagement with the under' face thereof at opposite sides of the battery post.

The plunger 10 which is adapted to engage the upper end ofthe battery post is formed from a metal rod and has its upper end p rovided with forks 11 between whlch an operv ating lever 12 is mounted by a rivet or other suitable fastener 13. The fastener 13 is firmly secured in'alined openings formed in the forksll and passes through aslot 14 formed longitudinally of the lever so that the lever which is pivotally mounted upon a pin lbetween the arms 16 at the forward end of the cross bar 2 and extends longitudinally above the same may be'freely swung toward and away from the cross. bar without binding taking place between the lever and the plunger. Theplunger passes downwardly through an 'opening 17 vformed in the arm 3 and is also sli'dably received in an opening 18 formed in the arm 19 of the guide bracket .20 which is frmly'secured against the forward face ofthe standard 1 by rivets or other suitable fasteners 21. In order to yieldably resist movement of the plunger towards the -foot 4 and normally retain it in the elevated position shown, there has been provided a spring4 2,2 which is coiled about the plunger with its lower end resting upon `the arm of the guide bracket and its upper end engaging a washer 23 carried by the plunger and abutting a cotter keyY 24 passed through an opening drilled in the plunger.

When the battery terminal lifter is in use, the arms 7 of the foot 4 are passed beneath the terminal 8 and engage the under face thereof at oppositel sides of the post 9. 'The lever and the handle 5 are then grasped and pressure applied to move the plunger 10 downwardly into engagement with the upper end of the battery post, as shown in Fig. 2. Additional pressure is thenl exerted to force the plunger downwardly and draw the standard upwardly and the terminal will be moved upwardly out of engagement with the battery post. .If it is found that sufficient pressure cannot be exerted to detach the terminal from the battery posts pipes' or other auxiliary handle members may be engaged with the lever and handle 5 so that additional leverage may beobtained and greater force exerted. In most cases, however, suflcient force may be exerted by means of the lever and handle 5 to easily detach a bat.- tery terminal from its post. v Having thus described the invention, I claimz- 1. An extractor comprising a body portion including a standard and a cross bar carried thereby and constituting a handle and arm extending from opposite sides of the standard, a foot extending from said standard and beneath said arm adapted to engage an article to be detached from a companion article, 'a plunger' slidable through said arm towards and away from said foot, and a lever carried by said arm in overhanging relation `to the handle and plunger for moving said plunger into engagement with the companion article and exert pressure thereon to separate the articles when the lever and handle are Jforced toward each other.

2. An extractor comprising a body portion including a standard and a cross bar carried ythereby at itsV upper end and constituting a-handle and arm, a foot extendin from the lower end of said standard an adapted to engage an article to be detached froma companion article, a plunger slidable through said arm towards and away from arm and han le an pivotally and slidably connected with the upper end of said plunger and when swung downwardly towards the handle adapted to move the plunger into engagement with the companion .article and exert pressure thereon to separate the articles. 4

3.An extractor comprising a body portion including a standard and a cross bar carried thereby at its upper end and constituting a handle and arm extending from opposite sides of the standard, a footl extending from said standard beneath the arm and having forks adapted to engage beneath an article to be detached from a companion article, a plungerA slidable through said arm towards and away from said foot, a guide extending from said standard between said foot and arm and formed with an opening slidably receiving said plunger, an abutment upon said plunger above saidl guide, a spring aboutthe plunger between the guide and abutment to yieldably resist movement of the plunger towards said foot,A

and an operating lever pivoted to the outer end portion of said arm and extending longitudinally above the arm and handle and when moved downwardly exerting pressure upon said plunger to force the same towardsl the foot into engagement, with the com-l panion article and separate the articles.

In testlmony whereof I aifix my signature. CLARK C. ECHELBERGER. [Ll s]
