Device for carrying and lowering the horse-mould cover
Braced timber frame that inverts and sets down the cappa of the Sforza monument mould
The sheet shows a tall braced timber hoisting frame at left — a triangular A-frame with diagonal struts — and at right the mould-cover (cappa) for the head and neck of the Sforza horse, drawn as tall vertical mould pieces flanked by a ladder-like element and supported by upright timbers. The accompanying note explains that this instrument serves to carry and lower the cappa, and how to set it down either inverted (riverscia) or face-down (boconi) by removing the cross-brace and pulling the feet of the upright timbers at the points a b, or better by detaching and re-fixing the half-cappa to the whole instrument. The letters t, s, a, b key parts of the apparatus and mould.

Carrying and lowering the head-and-neck mould
The instrument carries and lowers the cappa (mould-cover) of the horse. To set it down inverted, the cross-brace is removed and the feet of the upright timbers supporting the half-cappa are pulled at the places a b; better still, the half-cappa is detached, fixed to the whole instrument and drawn up to where it must be lowered, then secured upright and perpendicular before being lowered with the ropes.
Braced timber hoisting frame with cross-brace
At left stands a triangular timber frame with diagonal struts and rollers that forms the lifting instrument; its cross-brace (crociera) can be removed and the feet of the upright legs shifted to change how the mould is set down. The frame is carried to the opposite side to lower the cappa inverted or face-down.
Lettered key of the apparatus
The figure is keyed with the letters t, s, a, b, marking points on the hoisting frame and the mould, with a b naming the feet of the upright timbers referenced in the note.
