Gun carriages and a cart-pulling force test
Carriages for a bombard's tube and breech, with a wheel-and-counterweight force trial
Drawn in ink on blue prepared paper, this sheet gathers several wheeled artillery carriages (affusti) seen from different angles, one captioned as a carriage for the tube (tromba) and another for carrying the breech, or tail, of a bombard. At upper right a figure of a wheel, cylinder and counterweight is annotated with the number 100 and a note that it is a trial to measure how much force is needed to pull such a cart. A small detached fragment mounted below (labelled folio 932 b recto) is noted as bearing no writing.

Carriage of the tube (tromba)
A wheeled gun carriage on the left half of the sheet is labelled the carriage of the tube. It is one of several artillery mounts studied here in different views.
Carriage for a bombard's breech
A second carriage is described as a cart for carrying the tail, or breech, of a bombard. The drawings show splayed-leg wheeled frames designed to transport the heavy gun components.
Trial of the force needed to pull a cart
A figure combining a wheel, a cylinder and a counterweight is marked with the number 100 and captioned as a test to see how much force it takes to pull a cart. It treats the haulage of the gun carriages as a measurable mechanical problem.
