referring now to the drawings , and , more particularly , to fig1 , and 3 , an embodiment to be preferred of an anti - corrosive battery terminal 10 , made according to the present invention is disclosed . battery terminal 10 is in the form of a terminal block 20 defining a battery receiving socket 30 , a grease fitting 40 ; and clamp means 50 . terminal block 20 may be constructed of any suitable material , either electricity conducting or insulative . it is preferred however , that the block be made of conductive material for conduction of electricity to terminal contact posts 55 , as will hereinafter be explained . copper and bronze are preferred metals for construction of the block and doped plastics , also called conducting polymers , such as polyacetylene doped with iodine , may also be highly desirable because of its high electrical conductivity as well as its ability to be molded . the block is preferably in the form of a cube , having outer surfaces including the top 21 and the four sides , designated generally by the numeral 22 , and having an undersurface 23 on the opposing side from the top . formed , by machining or otherwise , on the bottom surface 23 is a battery post receiving socket 30 which is slightly larger in all dimensions than the battery post 5 of battery 3 . also formed within block 20 is a threaded conduit 27 , extending between socket 30 and the outer surface of the block . in the preferred embodiment conduit 27 extends between the socket and top surface 21 for the placement of grease fitting 40 . grease fitting 40 , one type of which is shown in fig4 is provided with threads mateable with the threads of conduit 27 so that the fitting may be simply screwed into the conduit . fitting 40 , also known as a grease &# 34 ; zerk &# 34 ;, includes a check valve , designated generally be the numeral 45 , forming an effective seal , and also includes a post 44 , rising vertically from block 20 , for convenient engagement by a grease gun , not shown . while fitting 40 may be located anywhere on the block , for ready access it is mounted through top 21 of the block . also mounted on block 20 are a selected number of terminal contact posts 55 for the attachment of electrical wires leading to the starter , other batteries , auxiliary units , etc . contact posts 55 are constructed of any suitable material and are preferably in the form of steel machine bolts which are screwed into threaded apertures 57 in the block . where block 20 is constructed of electricity conducting material , electrical contact between posts 55 and block 20 may be sufficient , although it is always preferred that posts 55 make contact with the battery post 5 . where block 20 is constructed of electricity insulative material , contact between posts 55 and battery posts 5 must be made . it is obvious that one or more contact posts 55 may also serve as clamp means 50 for attachment of block 20 to the battery post . for installation of terminal block 20 onto battery post 5 , the battery post should be clean and free of oxides and other forms of corrosion and the interior surface of socket 30 of block 20 should also be free of grease or other contaminants . the block is simply placed over post 5 with socket 30 surrounding the post about the sides and top . if desired , though unnecessary , a porous fabric washer 9 , well known in the art , may be placed around the base of battery post 5 . clamping means 50 , in the form of contact post bolts 55 , are then screwed into threaded apertures 57 until the flattened , blunt end of the bolt securely engages the battery post to obtain maximum electrical contact surface . while a single bolt may serve to clamp the block in place to the battery post , it is recommended that at least one other bolt 55 make contact with the post , and , as before stated , contact is necessary where block 20 is constructed of insulative material . once bolts 55 are in place , corrosion preventive grease , or the like , is injected through grease fitting 40 into socket 30 to completely fill the socket . excess grease exiting the base of the socket at the undersurface 23 of block 20 may simply be wiped away . if porous washer 9 is in place , air readily flows through the washer to prevent any air bubbles within the socket , and the washer soon becomes saturated with grease to form an air tight seal . it is to be particularly noted and is an important part of the invention that all contacts between terminal contact posts 55 or clamping means 50 and battery post 5 are made before the addition of any grease so that the grease , which is electrically insulated , can in no way impair the contacts . it is also to be noted that electrical contact can be made over a large surface area between the blunt end of bolts 55 and the battery post . having thus described in detail a preferred embodiment of the present invention , it is to be appreciated and will be apparent to those skilled in the art that many physical changes could be made in the apparatus without altering the inventive concepts and principles embodied therein . the present embodiment is therefore to be considered in all respects as illustrative and not restrictive , the scope of the invention being indicated by the appended claims rather than by the foregoing description , and all changes which come within the meaning and range of equivalency of the claims are therefore to be embraced therein .
