AMBU POST STRAP MOULD
Perhaps the most expensive item of a stock in a battery station, is the supply of positive and negative groups. While two or three sizes of plates will fit practically every battery, each size battery requires a different size of group.
Figure 10[[1]]
The AMBU-Washburn Post Strap Mould has been developed in order that a comparatively small stock of plates can be instantly available for making any size of group. You will notice in Figure [10], that the same features, as those of the link mould of Figure [8] are used, namely; a large substantial base, no need of handling hot parts and the easy removal of castings. All parts of the moulds are carefully machined to produce perfect castings and the patented movable tooth rack will make odd or even numbers of teeth on the post strap. The teeth are correctly spaced for all standard batteries, or by reversing the tooth rack, blank posts can be cast.
Two bushings, bored and reamed for standard size posts, are furnished, but special bushings are available making it possible to cast any type of post strap.
