Carriel’s patent was first issued February 7, 1832, but was cancelled “on account of a defective specification.” The patent was re-issued here, accom-panied by the inventor’s two-page description: “the geering or communication between the drum & screen is to be so adjusted as to give about four revolutions of the drum to about one of the screen; that being the difference which I find most perfectly to effect the object of dusting the rags thoroughly.”

Partial Transcript
“I George Carriel…have invented a new and useful improvement in ‘Cleaning rags’”…
“…it will be seen that the box or hollow bushing of the screen, revolves on the gudgeon of the drum or cylinder, and in the same direction, though with different velocity, as will be explained thus; that the geering or communication between the drum & screen is to be so adjusted as to give about four revolutions of the drum to about one of the screen; that being the difference which I find most perfectly to effect the object of dusting the rags thoroughly.”
