Gwilt translation

4There was also a middle floor above the small beams, where the scorpions and catapultæ were placed. Two upright pieces were also raised, joined together, thirty-five feet long, a foot and a half thick, and two feet wide, united at their heads, dove-tailed into a cross beam, and by another in the middle, morticed between two shafts and tied with iron hooping, above which were alternate beams between the uprights and the cross piece, firmly held in by the cheeks and angle pieces. Into the framing were fixed two round and smooth axles, to which were fastened the ropes that held the ram.

Morgan translation

4It had, moreover, a middle flooring on girts, where scorpiones and catapults were placed. There were set up, also, two framed uprights forty-five feet long, a foot and a half in thickness, and three quarters of a foot in breadth, joined at the tops by a mortised crossbeam and by another, halfway up, mortised into the two shafts and tied in place by iron plates. Above this was set, between the shafts and the crossbeams, a block pierced on either side by sockets, and firmly fastened in place with clamps. In this block were two axles, turned on a lathe, and ropes fastened from them held the ram.
