The Spring Engine
The arm was bent and then retained in this condition by a slip-hook
similar to the one shown in fig. 216, p. 316. The arrow rested on a block
of wood with a groove along its centre as in the stock of a crossbow. The
trajectory of the arrow was arranged by means of an adjustable prop. This
was hinged to the under-side of the piece of wood on which the missile
was placed, fig. 217, p. 317.
That the spring engine was a serviceable one when of large size is beyond
question, though its range and power are conjectural. With a model I have
discharged a crossbow bolt 160 yards, the wooden spring of the model being
5 ft. in length and formed of eight strips of ash each 3 in. broad and
1/4 in. thick.
From 'Ancient Tapestries.' A. Jubinal. Paris 1838.
