G. Wood plate, 3 inches thick.
H. Lead-flat.
I. Joists to ditto.
J. Ceiling-joists.
K. Principal beam of roof.
I must give you to understand the bow, lead-flats, &c., were done before I came here, and supported in a manner that gave offence to every one; you will now perceive there is a straight ceiling and no obstruction to light or any thing else.
The suspension-rods are fixed to the bolts as the link of a chain, the brace screws them tight together, and the bottom nuts screw up and camber the plate, which renders the whole complete and very strong. I had it put together and fixed in about two hours, so that you will perceive it can be applied in any situation without doing any damage, by merely boring the holes and making good the joint round the bolts on either a floor, roof, or flat.
I have applied others in different places, and have made them as circumstances required, to carry scores of tons weight. They have given the greatest satisfaction possible to all concerned.
I am happy to inform you that our architect and the master-builder will both be subscribers to your valuable work. I think from this neighbourhood you will have a dozen names.
Yours most obediently,
