BATTERY TERMINAL.

Application filed April 13, 1927. Serial No. 183,327.

tionally'clamped by their drawbolts onto batiery terminal posts and they invariably corrode on said posts so that it is usually very difiicult to remove thesame without considerable pounding'and prying, which is detrimental to the battery. Furthermore, the ends of split terminals are often drawn so close together during their application to battery posts, or the shape thereof is such that it makes it difficult to insert a tool between the ends thereof for the purpose of spreading the same to release the terminals from battery posts.

The object of my invention is to provide a split battery terminal with a pair of co-operating spreader lugs at the end portions thereof between which a tool may be inserted for the purpose of prying the ends of said terminal apart to release the same from a battery post to which it is applied. These spreader lugs are so arranged that they cannot be completely drawn together, even if the end portions of a terminal are closely drawn together. Said invention further provides an ttaching lug for the application of a tool to lift a terminal from a battery post.

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts thro ghout the several views.

Referring to the drawings:

Fig. 1 is a perspective view of a split terminal applied to a battery terminal post and having the invention embodied therein;

Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1, and further showing a tool inserted between the spreader lugs Fig. 3 is a view corresponding to Fig 2, with the exception that the ends of the split terminal have been drawn together; and

Fig. 4 is a view corresponding to Fig. 1 but showing a slight modification with the terminal removed from the battery post and the drawbolt removed from the terminal.

Referring first to the invention as shown in Figs. 1, 2 and 3, the numeral 5 indicates one of the terminal posts of a battery and the numeral 6 indicates a split battery terminal applied to said post and having a split sleeve 7 for attaching a cable, not shown, to said terminal. A nut-equipped bolt 8 is inserted through aligned bores in the end portions of the terminal 6 for drawing the same toward each other and frictionally clamping said terminal onto the post 5.

A pair of co-operating upstandingspreader lugs 9 are integrally formed with the end portions of the terminal 6, and it is important to note that they are laterally offset at 10 from the opposing faces of the end portions of said terminal. To spread the terminal 6 to release the same from the post 5, a tool a; is shown inserted between the spreader lugs 9. The purpose of oifsettingthe spreader lugs 9 from the opposing faces of the end portions of the terminal 6 is to prevent the same from being completely drawn together and thereby prevent a tool from being inserted therebetween, even in case the end portions of said terminal are drawn tightly together, as shown in Fig. 3.

Referring now to the invention as shown in Fig. 4, the spreader lugs 11 on the end portions of asplit terminal 12 are the same as those shown in Fig. 1, with the exception that their inner ends are reinforced at 13. Said spreader lugs 11 are laterally offset from the opposing faces of the end portions of the terminal 12, as indicated at 14. The terminal 12 is provided with a split sleeve 15 for use in attaching a cable to the terminal. Also integrally formed with the terminal 12, at the sleeve 15 but inward thereof, is an upstanding tool-attaching lug 16 having an outturned lip 17. The purpose of the lip-equipped lug 16 is to afford means by which a tool may be applied to the terminal for use in lifting the same from a battery post.

What I claim is:

1. A split ring battery terminal having cooperating lugs on the upper surface of the outer end portions thereof, said lugs proj ecting upward an appreciable distance from said upper surface, the inner surfaces of said lugs being offset from the inner surfaces of the ends of the ring so as to provide a space between the lugs which in all positions of the terllninal, is capable of receiving a spreading too 2. A split battery terminal having a pair of spaced upstanding co-operating tool-engaging lugs integrally formed with the outer end gaging lugs integrally formed with the ouh-r portions of the terminal, said lugs projecting end portions of the terminal, said lugs pl'u- 10 above the upper face of said terminal, at least jecting above the upper face of said terminal, one of said lugs being laterally spaced outsaid lugs being laterally spaced from'the inward from the inner face of the respective ner faces of the end portions of said terminal. end portion of said terminal. In testimony whereof I aflix my signature.

3. A split battery terminal having a pair of spaced upstanding co-operating tool-en- HENRY E. PIEH.
