To quickly assess the difficulty of the text, read a short excerpt:
Rollers draw the hay from the trough, and the twisting is effected by a planetary action of the rollers longitudinally ; it is then coiled on the reel.
Since the introduction of the above-described machine there have appeared others of more or less merit, but with many it remains a matter for conjecture whether there has been any substantial improvement made.
142 THE IRON-FOUNDER SUPPLEMENT.
GEAR-MOULDING BY MACHINERY.
Owing to the various difficulties caused by irregular ramming, unequal expan...sion of patterns arising from the different degrees of dampness in the sand, as well as the lmost certain destruction of some parts of the mould dur- ing the withdrawal of the pattern, and which could at best be but approximately repaired, it is safe to say that very few gear-wheels of magnitude were ever made true before Jackson, of Manchester, England, invented his machine for forming part of the mould and spacing the teeth with mechanical accuracy in the sand, one tooth only being used for producing the whole number contained in the wheel, this one tooth being alternately raised and lowered by suitable machinery, which not only draws the pattern with absolute precision, but travels to the next tooth as precisely as could happen in the best gear-cutting machine.
