The old mode of making brass kettles was by hammering upon a sheet of metal, until by degrees the required shape was assumed.
The plan now in use is known as “
Hayden's patent,” December 15, 1851.
Square blanks of sheet-brass are cut into circles of a diameter corresponding to the size of kettle required.
After annealing, the metallic disks are brought in contact with cast-iron chucks revolving horizontally with great velocity.
A small steel friction roller, resembling a button, is then brought in close contiguity to the metal, and, running along the outer surface of the blank, spins it out to the shape of the mold.
Four such operations are commonly required before the kettle assumes its finished form, the metal requiring to be annealed after each.
The course of the roller is marked by the concentric rings which are found upon most of the brass kettles in market.
The processes of wiring, fixing on the ears and bales, are all required to make the kettle complete.
Sizes range from 1/2 gallon to 32 gallons capacity.
