Samuel Blatchford, Royer v. Schultz Belting Company…
“ In order to accomplish our object, we employ a machine mounted on a suitable frame, having a vertical slotted shaft, to which is attached, at its base, a beveled wheel between two beveled pinions, upon a horizontal shaft. Around the vertical shaft is placed a row of vertical pins or rollers, held in place by upper and lower rings, one of which is firmly bolted to the frame. An iron weight or press is employed for crowding the coil of hide down after it has received the forward and back action around the shaft. ”
