Field of the Invention:

2) State of the Art:
I .
¦ Battery terminals are subject to extreme corrosive ¦ action and, thus, it is highly desirous to form a battery con-¦ nector clamp so that it will be resistant to such corrosive actiol .
¦ Therefore, it is desirous to form the clamp from metal. But, ¦ conventional battery connectors are in the form of a U-shaped ¦ clamp or split socket having substantially parallel legs that ¦ are clamped onto a battery post by a bolt assembly passed through ¦ openlngs in the legs. Thus, such connectors must be constructed ¦ from soft pliable metal so that the legs can be moved towards ¦ each other in clampingly engaging a battery post under the 1:
¦ tightening action of the bolt unit. Due to the soft nature of ¦ thè metal, the connectors are subject to deformation and the legs are prone to 51ip on the post. Further, the legs of such conneot rs do not grip the post with sufficient force.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now more particularly to the accompanying drawing, the battery connector clamp 10 is composed of a coop-erating pair of blocks or jaws 12 and 14. The jaws are of solid construction and are formed from lead or other similar non-corro-sive hard metal. The inner end 16 of the clamping jaw 12 is :
~ .
,~ ., -: , - . :
! .
flat and is adapted to abut tight against the inner flat end 18 of the jaw 14, as shown in Fig. 1. The complemental inner ends 16 and 18 are formed with semicircular cut-outs 20 and 22 which cooperate in the clamped position of the jaws 12 and 14 to form a circular opening 24 for receiving a battery post 25 shown in dotted lines in Fig. 1. The opening 24 is shaped so as to clamp-ingly receive the battery post 25 and is of a larger diameter at ¦the bottom face 26 than at the top face 28 of the clamp 10, as ¦shown in Fig. 3. The clamping jaw 14 is of semicircular configu-¦ration with its flat inner end 18 and an arcuate outer end 30 ¦while the member 12 is of substantially rectangular shape having ¦the flat inner end 16 and a parallel flat outer end 32. Both of ¦ the jaws are of similar thickness with such being substantially ¦equal to the length of the battery post.
The clamping jaws 12 and 14 have grooved outer sides Iprovided to receive the parallel shanks 34 and 36 of a U-bolt 38.
¦ The outer sides 40 of the jaw 12 diverge outwardly from the inner ¦ end 16 to the outer end 32 so that the sides at the outer end ¦portion 32 are wider than at the inner end portion 16 for stiffen-¦ ing and ridigification purposes and also so that the grooves in ¦ the sides of the jaw 12 are of a greater depth at the outer end ¦ portion than at the inner end portion. The outer ~ree end por-tions of the shanks 34 and 36 of the bolt 38 are completely housed within the outer end portions of the grooves 42 adjacent the outer end 32 of the jaw 12. Thus, the grooves 42 increase in depth ~towards the outer end 32 and reach a depth at such end that is at ~¦ least e al to the diameter of the shanks of the bolt.

Il 11119~ ~
l The opposing sides 44 of the clampin~ jaw member 14 have ¦grooves 46 which are in alignment with the grooves 42 for the re-¦ception of the shanks of the U-bolt 38, as shown clearly in Fig. 1 The sides 44 adjacent the inner end 18 of the jaw 14 have enlarge-ments 45 that are of the same thickness as the inner end portions ¦of the sides 40 of the jaw 12 with such enlargements having groove ¦that complement the inner ends of the grooves 42. The arcuate ¦outer end 40 of the clamping jaw 14 is provided with an arcuate ¦groove 48 in which the bight portion 35 of the bolt-is fitted with ¦the groove being formed below the bore 50 in which the bared end 152 of a conductive cable 54 is fixedly mounted, the cable being ¦enclosed by a lead sheathing 56. The cable end 52 is mounted in ¦the bore 50 above the bight portlon 35 and below a lip 58 formed ¦centrally on the top of the outer end of the jaw 14 with the end ¦portion of the cable being protectively positioned between the jbight portion and the rearwardly projecting lip 58, as shown in Fig. 2.
¦ A flat clamping bar 60 is provided and is formed at its ¦end portions with apertures 62 that fit on the outer end portions :
of the shanks 34 and 36 of the U-bolt 38 in a manner so that the ¦flat clamping bar 60 extends between the shanks and fits tightly : ¦against the flat outer end 32 of the clamping jaw 12. The outer ¦ends of the free end portions of the bolt shanks arP exteriorly ¦threaded to receive nuts 64 which bear against the clamping bar ¦60 and whereby the bar 60 cooperates with the bight portion 35 ¦of the bolt to tightly clamp the clamping jaws 12 and 14 on the :~ -¦battery post 25.
~: , ~ In use, the jaw 14 has the end o~ the conductive cable , I .

'`~ ' j ' ~
- - . . . . .:
¦ attached thereto and the jaw is positioned on one side of the ¦ battery post 25 with the jaw 12 being disposed on the other side.
¦ The jaws are brought together so as to encircle the post and the ¦ shanks 34 and 36 of the U-bolt 38 are slid into the aligned ¦ grooves g6 and 42 until the bight portion is seated firmly within ¦ the arcuate groove 48 in the outer end 30 of the jaw 14. In such ¦ position the outer threaded free ends of the shanks 34 and 36 of ¦ the U-bolt 38 project beyond the outer end of the jaw 12 and the ¦ inner ends 18 and 16 of the jaws are in tight abutting relation.
¦ The clamping bar 60 is then placed on the ends of the shanks and ¦ the nuts 64 are screwed onto such shank ends until the bar is ¦ forced tight against the flat outer end 32 of the jaw 12. The ¦ jaws are tightened onto the post so that the post will not smoke ¦ and so that the jaws cannot become accidentally loosened.
¦ Thus, when the jaws are tightened on both sides of the ¦ post so as to completely clampingly encircle the post, the clamp ¦ will stay tight. Thus, the battery will not lose its power.
¦ The clamp 10 can be formed with the cable end molded in ¦ the jaw 14 or the jaw can accommodate a replacement cable. Also, while the clamp 10 can be put on one end of a conductor cable to fix the cable to a battery post, it is envisioned that the clamp can be on opposite ends of a cable used to couple a pair of batteries together.
:1 Thus, it is to be understood that the foregoing des-~ cription and the illustration in the drawing merely relate to an ,:~ exemplary form and environment of the present invention, which is ¦¦ solely 1 it ed by the terms and 5cope of the appended claims.
