US Patent 4,275,515 (Betty R. Hinson, granted 30 June 1981) for a frame-and-guide apparatus for making handcrafted pile rugs. A backing fabric is stretched on a pinned rectangular frame, and a comb-like pile forming guide set at adjustable heights holds yarn loops while each tuft is sewn and knotted into the backing with a needle, giving uniform pile spacing and height.
