US Patent 1,332,122, granted 24 February 1920 to Frank Glatzel of Paterson, New Jersey, for an improvement to the Jacquard machine. Grooved, oil-filled rails bolted to the main frame carry rollers on the frame holding the card cylinder. The rollers take the cylinder's weight off the bearings and rods, which reduces binding and wear, and the attachment can be fitted to a standard machine without altering it. The scan has two sheets of drawings (Figs. 1-7), the specification and two claims.
