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.
AMBU PRODUCTION POST STRAP MOULD
For the large shop or manufacturer, the AMBU-Washburn Post Strap Mould, is made with the special indexing feature of Figure [11]. This is easily adjustable and will cast straps of both odd and even numbers of teeth for 7 to 19 plate groups. Otherwise its construction and appearance is the same as Figure [10].
Both of these moulds are made for real use and will turn out three perfect castings per minute. This unusual speed can be maintained because the castings are easily removed. In Figure [10], the upper part of the mould is resting on a part of the handle made for that purpose and a slight blow on a hardwood stick, on the top of the post, will drop the casting instantly.

AMBU CELL CONNECTOR MOULD
The AMBU-Washburn Cell Connector Mould is a combination mould which will cast practically all of the cell connectors used on standard storage batteries, 7-11-13 and 15 plate, such as the Exide, Willard, U. S. L., Vesta, Philadelphia and other nationally known batteries. Its design is similar to our Link Combination Mould.
Made of fine gray iron, carefully machined. Castings are easily removed, and it is heavy enough so that it will not overheat where speed is required.
