Press Mat.
Patent for a new and improved cotton-seed-oil press mat. This design calls for three separate plates to be bound together, which allows for two pressings simultaneously. The materials (sheet metal, leather, press cloth) make for a press that is stronger, cheaper, more durable, and more effective than previous presses.
