The other parts used in Ceoss-Baes, Steaps, Teeminal Posts, Conneotoes, Etc. 169 connection with this design are also shown in the figure. 5 is a soft rubbergasket, two of which are used with each strap and terminal post. One ofthese gaskets is placed directly on top of the flange A, thus forming a softrubber seat and seal between the strap and the cover; the other soft rubbergasket is placed on top of the cover and between the alloy washer D and theretaining nut C, the alloy washer D thus forming a substantial purchaseagainst which the retaining nut is placed when this nut is screwed type of strap and terminal post has given good results under regularservice operating conditions, and it is considered to be one of the best. Fig. 68.—Flanged and Threaded Strap and Terminal Post. methods at present used for attaching and sealing the cover to the strap, aswhen properly assembled and given the necessary attention, it forms aneflfective seal against acid creeping, which is so prevalent in storage batteryinstallations. In some modified forms of this design the nut G is sometimes made ofhard rubber, and in some instances these nuts are made of brass or bronze,usually lead-plated. As a rule, it is considered that the lead-antimony alloynuts and also those of hard rubber are superior to the brass nuts, in thatthe use of brass nuts violates the principle of design that the nuts should becomposed of a softer material than the threaded portion of the strap. Thesoundness of this principle is obvious, since it is apparent that the nut canbe more readily and ea
