No. XXVI.

To raise a weight so well and as forcibly with the drawing back of the lever, as with the thrusting it forwards; and by that means to lose no time in motion or strength. This I saw in the arsenal at Venice.

NOTE.

The mere application of a crank, such as is used for the foot-lathe, acting upon a drum and fly-wheel, with a chain attached to move a second lever or upright sliding bar, will fully effect the object here described.
