To all l/IIONZ it may concern Be it known that I, GERHARD E. Fistu a nnrrnn. a citizen of the United States, and a resident of Princeton, county of Gibson, and State of Indiana, have invented a certain new and useful Process and Means for Removing Corroded Terminals from Storage Batteries; and I do hereby declare that the following is av full, clear, and exact description thereof. reference being had to the accompanying drawings, in which like numorals refer to like parts.

This invention relates to the process of andmeans for removing corroded terminals from a storage battery.

The chief object of the invention is to remove the corroded terminal from a battery terminal post with a minimum of effort and in the most economical manner by suitable and the corroded terminal to heat the latter from energy derived from the battery.

Another object of the invention is to construct means for heating the corrosion upon a corroded battery terminal in the most economical manner.

The chief feature of the invention consists in utilizing the energy contained Within a battery for heating the corrosion upon a battery terminal in an electric circuit including the battery which will permit the terminal to be separated from the battery post.

Another feature of the invention consists in the construction of the heating means and its ease of attachment to a source of energy, as well as the simplicity of the heating means.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings. Fig. 1 is a top plan view is herein shown prgyided with g-termina'l postsjitl. Associatedjvithjheterfiifialposfs 11 are the usual terminal clamps 12 having a clamping bolt 13 and cable socket 14. In Fig-.11, one of the battery terminal clamps is shown corroded, as at 15. and such corrosion renders the removal of the clamp use of electrical means for heating said corrosion, and preferably said electrical means is associated with the battery which contains the corroded terminal desired to be removed. The particular electrically energized heating means. however, may be associated with another battery, but in this event the corroded terminal clamp must be inelectrical connection With the other battery. This use of the particular electrically energized heating means is only utilized when the original battery is in such condition that it cannot supply energy to the heating device. l

.The heating device includes a suitable contactclamp 16 adapted to engage a contact wire 17 which is the usual cable associated with one of the battery terminals 12. The

contact clamp 16 thus is readily attachablen to the cable 17 or may be adapted to engage the terminal post or a connector 18 ofthe battery. The contact clamp 16 is in electrical connection with one end of a current earrying cable 19 of any desired or suitable length and said cable terminates in a contactrstrip or lug 20. The particular heating element may be of any desired construction and associated with the lug 20, and herein What is deemed the simplest form of sudh an element is illustrated. The heating element comprises the carbon stick 2]. having a pointed end 22 and carries at its opposite" end a. terminal screw 23; A cap consists of a unitary sheet cut to form a band 24 attached to a: circular )ortion 25. The circular portion 25 is periorated at 2-6 to receive the screw 23* Each end of the band 24 is apertured at 27. and said ends are bentinto parallel relation to provide ears 28. A bolt 29 associated With a nut 30 passes throu h the openings 27 and is adapted to draw t e band tightly about one end of the carbon p asan A nut 31 is adapt/ed t!) secure thi 116 v 5 portion.

lug 20 upon the screw :23 and thus the-lug 20 is in electrical contact with the circular end 25, which in turfi contacts the carbon pencil at the end and also through the band When the contact terminal 16 is connected to a storage battery and the pointed end 22 of said stick is in contact with the corroded terminal 12. the latter being included in the battery circuit supplyin; en-

1 ergy to the carbon stick. said stick forms an arc and generates heat and thus heats the corrosion 15 which permits the terminalclampto be readily removed. The carbon stick Wears away with use and can be read- 15 ily replaced in the device.

The intention claimed is:

1. The process of removing a corroded terminal from a storage battery consisting of passing an electric current through a heat 1'" generating element and the corroded terminal for heating the corrosion.

2. The process of removing a corroded terminal from a storage battery consisting oi short circuiting the corroded terminal throu h an arc enerati v element connected to the battery.

3. The combination oi a storage battery having a corroded terminal, an are forming device for heating said corroded terminal, and a current carrying means connecting said are forming device with the battery for supplying energy to the device for heating purposes.

4. The combination of a corroded termi nal. a source of electrical energy. an electrically energized are. forming device, and

means connecting said device. said battery i and said terminal in an electric circuit for the purpose described. i

In witness whereof, I have hereunto atfixed my six nature.
