. BATTERY TERMINAL.

' Application Be it known that I, WILLIAM Bonn-i notions, a citizen of the United States, re- 2 siding at Junction City, in the county of certain new and useful Improvements in Battery Terminals; and I do declare the following to be a full, clear, and exact dcscript-ten of the inventiomsuch as will-enable others skilled in the art to which it ap- 1 tion.

I secondary socketed member over the binding binding post use the same, refer- "pertains .to make and accompanying drawence being had to the ings, and to the figures thereon, which form a part of this specifica- This invention relates to a terminal for batteries and the primary object thereof is to provide a terminal fastening for the cable so that the cable can be secured 20 to the binding post in such a manner that it i may be disconnected without danger of breaking the battery cell.

. Ordinarily connections are made between the cable. and the binding post by placing a post and fastening it in place bya set screw. After a while the socket and binding post freeze or stick together on account of corrosion which sets up between the socket and the or be members of tar the connection, Then in 9 er to disconnect the cable from the bindmg post, the binding post is put under severe strain resulting in its being broken oil, in many instances, so that a new binding post has to be burned on.

desired result battery y invention contemplates the elimination of the above mentioned difiiculty and the is accomplished by novel means'which will be s ecifica'lly referred to hereinafter, reference eing had to the accompanyi-ng drawings, in which 'Fig. 1 is a perspective view of a battery terminal constructed in accordance with my invention.

Fig. 2 is a sectional view through the terminal showing the parts in position for making the connection.

Fig. 3 is a similar view showing the complementary members disconnected, and

Fig. 4 is a sectional view through the socket member and a securing nut for fastening it to the binding post.

The battery 1 may be of approved construction with a bindingpost 2 in the form of a truncated cone with an and State of Kansas,-have invented' out of the binding '5 carried by the soc .internal conical socket on recess of reference marked ner. The nut -is therefore ween the two 'complemenmed ibiarch 28,1924. serial No. 702,610.

upstanding threaded stud 3 pro ecting above the truncated portion of the inding post. For c0nvemence, I may utilize a bolt with ahead 4 a cast in the binding post asclearly illustrated in'Fig. 2. The head 4; serves as an anchor to prevent the studrrom being pulled et member 6.

The socket member: is provided with an 7 dapted ost bythe adjusting nut] to tightly fit over thelbinding 01st 2 and'it' isprovided withta shouldere portion or seat 8 to receive the flange 9 of the nut 5 havin a polygonal portion 11 so, that it may e received between the jaws of a wrench." 'llhe'flange is held cover plate 12 fastened to the socket-member 6 or thesocket member can be loosely secured to the nut in any well known manadapted to have rotative movement with respect to the socket member, therefore when the on the stud 3, the socket forced down on the binding post to make electrical connection between the complementary fastened When it is desired to disconnect the com; lementary members 2 and'G, a wrench may e applied to the polygonal portion 11 of the nut 5, which ert. a straight et member so 6 are stuck together by corrosion, the force will be sufficient-to pull them apart because the nut and stud will act as a" screwjack exerting great power and since the strain will be on the stud and on the binding post V 2, no strain will be communicated to the nut 15 screwed member will be on its seat by a members 211ml 6, the cable 14' bein to the socket member in the usua upbn'belng' unscrewed will ek- A longitudinal pull on the sockthat even if the members 2 and cell, 'consequentlyliability of the cell becoming broken will be entirely eliminated.

I It will be apparent from the foregoing that the connection between the cable an the binding post may be made and broken m a very convenient and expeditious manner and that liability of disruption of the battery jar or cell in making and breaking the connection will be entirelyeliminated. What I claim and desire to secure by Letters Patent is:

1. A battery terminal comprising a binding post, a socket member to fit over the bindmg post, a nut rotatably mounted in the no,

D post aha nu'- being rotatabie 131 one on to force the socket member long? 111 11y upon the binding post and ro zatw in an opposite directien for forcing sosket' member away from the binding post.

In cnrnbination,a'biufling post includ ing threaded projecting stud, a socket member having lon itudinal movement with respect to the binding 730st a rotative nuu carried by the socket member and a, cave? plate carried by the socket member to 110M the nut in rotativc engagement with thc socket member, the mm; having co-operative movement with the siud so that when it is turned in G116 direction, it will force the socket member in intimate Contact with the binding post and when is moved in the other direction, it will move the snckei member out of suntact with the binding post.

In testimeny whereof afiix my signature.
