SIDE HEADS 12-bitted ship-lap or 6-bitted round jointer heads may also be furnished if desired These heads as well as others may all be sharpened on our Pede- stal Side-head Grinder. We have the only 12-bitted side-heads ever manu- factured. Side-head jointer is also furnished. BELT TIGHTENERS ..t, ,Thert, are two features about our automatic belt tightener construction that stand out prominent. In a recent test covering a period of nine months, night and day run in one of the largest plants in the world, a Berlin "90" a stock-model as above, ran night and day for over nine months and durinl that entire period not a single belt was taken up. Every tightener is autJ matic, works on the slack side of the belt, and the belts may be released *bl lifting up the tightener pulleys. These flexible tighteners as compared witl the screw method by which terrific pressure and friction is applied to th| belt, make a saving of 25 to 50 per cent, in the horse-power required to drrvl the machine. Belts may be put on endless and run for months and year!) without being taken up. There is no unnecessary strain on the belts and thfi heads will handle the heaviest cuts. The life of the belts is tripled. CHAIN DRIVE In place of the great number of gears which are found on any othe matcher, the number of which run up to 30 to a machine, we designed at automobile chain drive consisting of a power automobile chain running ovejj hardened
