What reading level is A Rudimentary Treatise On the Locomotive Engine in All Its Phases: Popularly ... book?
To quickly assess the difficulty of the text, read a short excerpt:
The springs are either spiral or flat springs, like those in the engraving ; or a circular steel hoop, a httle larger than a circle touching the ends ot the wedges, is forced in so as to bear against them. These pistons are liable to a defect from which the other with the spring rings is free — that of wearing grooves in the cyHnder where the points of the wedges rub against it, as the wedges have to wear down faster than the segments. The plan shown in the engravings is very efficient, and app...ears on the whole to be the best. The hemp packing used sometimes in sta- tionary engines is now generally superseded by metalHc pack- ing, as it requires frequent renewal and is unequal in its pressure, the piston having to be packed very tight at first in order to keep so for any considerable time ; in a loco- motive, where the motion of the piston is very rapid, it would be quite inadmissible.
The piston-rod is If inch diameter, and is made conical at the end, being increased to 2^ inches diameter in the centre boss of the piston, which is fitted upon it very exactly, and fixed by a cotter or key ^ inch thick, and tapered slightly from H inch wide; the piston-rod has to be fixed very firmly, and is split at the end to prevent its getting loose.
