A single-page broadside advertising a patented domestic machine for roving and spinning cotton and wool. The subscribers, Joshua Shaw and Stetson Lobdell of Portland, claim the 12-spindle machine is simple, easily repaired, and can be operated by a child, and they give a cost comparison against hand spinning. They offer machines for $50 and patent rights for $20, and they warn against infringement in the District of Maine and the state of Massachusetts.
