Vignelli ignored Holman's paper shuffling and went on running through his spiel. "Then, at this 'museum,' I saw the machines which lie at the basis of my new invention."
"Museum?" Holmann raised his eyebrows at the unfamiliar term.
"It is, ah, like a cabinet of curiosities, but the size of a building. It is devoted to the history of the region where this Grantville came from. And since it was a region where people used many various and different technical devices, it is full of them. That is where I saw the 'mimeograph.' "
"They let you come and examine this freely, with no restrictions?"
"Well, not freely. There is a charge to visit the 'museum,' but it is really a quite small one. I could afford to return for several days in a row. They had a placard posted that indicated the costs. The fee is reduced for visits by groups of school children. Otherwise, as to 'with no restrictions,' yes. There were guards, but to prevent damage and theft. Not to prevent visitors from examining the exhibits closely."
"Very well. Go on."
"I saw this 'mimeograph.' It is not a press. It works on a very different basis, using 'stencils.' I thought that I could make one. With enough time and money and workmen. It would be difficult and very expensive to make, with much hand-fitting of metal parts, especially teeth, and the need for several springs, but it could be done."
"Expensive?"
"If I had tried to copy the 'mimeograph.' There was a lever to partly open the 'drum' so that it could grasp the 'stencil' for example. If the grasping foot did not come together precisely, the stencil would be torn loose and ruined. Many other complications. But I did not copy it. There was another machine, a 'hectograph' it was called. Much simpler, but calling for more complicated inks. I thought—if there were some way to combine these. That was when I saw the 'washing machine.' More precisely, when I saw the 'wringer' attached to the washing machine." Vignelli smiled.
"Wringer?"
"Two wooden rollers, fastened together and cranked by gears. The laundress feeds the wet clothing through them. The movement of the turning rollers moves the cloth through them; the pressure of the two rollers forces the water out of the cloth much more effectively than it can be wrung out by hand."
Holmann nodded. He could visualize how that worked.
"So," Vignelli beamed. "I thought. Take a tray, like the 'hectograph.' Run it through two rollers, one above and one below, as if feeding the cloth. But how to ink it? One more day, two more days, I came back and looked at them again and again. Then, on the third day, when I came in, I looked at the counter where the girl who took the fee I paid was standing. She gave me a receipt. She 'stamped' the date on it, with a mechanical device. It is quite delightful, and simple. I will have to make one some time."
"You are wandering from the point."
"Not really. To get the ink on the stamp, which transferred it to the receipt, she had a little tray, with a pad in it. Not something alchemical. Just a cloth pad inside the little metal tray, soaked with ordinary printer's ink. Boiled linseed oil and carbon black. She had that in a bottle. There was a hinged lid, so the pad could be closed at night so the ink did not dry out. When I asked her, she showed me how to ink the pad, just using a swab and letting it sink in. And then I knew. The hectograph tray, the inked pad—a thin silk covering is best, but fine linen such as is woven for ladies' handkerchiefs and collars will do—the stencil, the piece of paper on top of the stencil, another waxed sheet to protect the rollers from becoming inky, the whole thing moving back and forth between the two rollers of the 'wringer' until the paper is inked. Simple. Cheap. Anyone could make one—any decent craftsman, at least. It was like a divine revelation."
"Show me," Holmann said. "Archbishop Ferdinand invests in results, not concepts."
"See," Vignelli said after he had finished the first demonstration. "The operator can release or tighten the tension on the rollers. He can make a second pass if the ink is getting dry and the paper does not become dark enough the first time."
"I don't think that I believed you," Holmann said. "But it is clear. How many of these machines do you have available?"
"I have already completed ten. At least, my shop had completed ten at the time I began this journey and that was several weeks ago. I have five more almost finished and my assistants are in the workshop even as I talk to you here. I sold two—well, received orders for two—in Frankfurt on my way to Cologne. The eight available, I can deliver as fast as the parts can be transported, unless, of course, my head assistant, who left for Vienna the same day that I started north, has received orders there."
