US Patent No. 106,130, granted August 9, 1870, to George Davis and John R. Hoover of Elizabeth Port, New Jersey, for an improved hemp drawing frame. The machine uses rotary disks carrying oscillating comb-bars whose teeth are tilted by cranks and pins running in eccentric grooved disks, so the teeth enter and leave the fiber endwise. The first page is the patent drawing (Figs. 1 and 2) and the second page is the specification and claim.
