US Patent 1,944,815, granted January 23, 1934 to Adam F. Schuler of Philadelphia, for an improved Jacquard mechanism used on wide Nottingham lace-making machines. It adds a second 'rectifying' grid that descends as the lifting grid rises, taking up sag in the long harness cords running to the outer jacks. This removes the need for slack in the central cords and roughly halves the grid's travel, so the machine can run faster. The document has six sheets of drawings (Figs. 1-8) followed by the specification and four claims.
