This patent model demonstrates an invention for a scraper press with stationary stone and moving scraper; the invention was granted patent number 43796.
This patent model demonstrates an invention for a rotary printing press; it was granted patent number 9987. The press had several impression cylinders and inking stations arranged around a large type cylinder. A web of paper was moistened and folded concertina-fashion for feeding. It was printed at the first series of impression cylinders and refolded. Then it was turned, and printed on the other side at the next series. Finally, it was cut into sheets. According to Stephen D. Tucker’s History of R. Hoe & Company, this patent was bought by R. Hoe & Co., probably more to keep it out of the market than with a mind to its development.
This patent model demonstrates an invention for a rotary printing press which was granted patent number 194902. This press had a feed table to steer boards between the impression cylinder and the hollow plate cylinder, the inking apparatus was overhead. For branding, a heating unit was fitted inside the plate cylinder.
This patent model demonstrates an invention for an intaglio system that was designed to speed the operation of copperplate wiping, using an ordinary platen lever press. After paper was pressed against the face of the engraved plate, ink was piped from a reservoir to spaces under the plate and then forced up through holes in the plate into the engraved lines. Here the ink made contact with the paper. Unused ink was then sucked back out of the lines, leaving the plate clean as the platen was lifted again for the next sheet. The invention was granted patent number 30495.
This patent model demonstrates an invention for a platen printing press which was granted patent number 10588. This platen jobber was manufactured under the name, “Ruggles's Combination Job Press.”
This patent model demonstrates an invention for improvements in the printing press; the invention was granted patent number 4025. The patent details improvements in feed and delivery, in raising the cylinder, and in stopping the bed.
This patent model demonstrates an invention for a type mold; the invention was granted patent model 187880. The patent details type molds in which the jet of the newly cast type was broken off automatically as the mold was opened, saving a separate operation in the typecasting process. Mason was from Islington in Middlesex, England. His invention was patented in England in 1877.
This tinted lithograph of “Canon of Psuc-See-Que Creek Near Camp 41A" was produced after an original sketch by John J. Young (1830-1879). It was printed as Plate VIII in Volume VI, Part I following page 84, in the "General Report" by Lieutenant Henry L. Abbot in "Report of Lieutenant Henry L. Abbot (1831-1927), Corps of Topographical Engineers, Upon Explorations for a Railroad Route from the Sacramento Valley to the Columbia River made by Lieutenant R. S. Williamson (1825-1882), Corps of Topographical Engineers assisted by Lieutenant Henry L. Abbot, Corps of Topographical Engineers," 1855.
The volume was printed as part of the "Reports of Explorations and Surveys, to ascertain the most practicable and economical route for a railroad from the Mississippi River to the Pacific Ocean" in 1855 by A. P. O. Nicholson (1808-1876) of Washington, D.C.
This patent model demonstrates an invention for a rotary printing press which was granted patent model number 25069. The patent details improvements to Wilkinson's press of 1853, patent number 9525.
This patent model demonstrates an invention for a self-inking platen printing press which was granted patent number 9925. Four or more platens rotated intermittently around a single axis. The bed was rocked, clamshell fashion, against each platen in turn. Sheets of paper were fed to grippers on the uppermost platen, printed when that platen turned to the vertical, and then dropped to a pile beneath the press when the platen went to the bottom position.
This patent model demonstrates an invention for a book stitching machine which was granted patent number 265563. The machine includes improvements in sewing signatures of books. Stitches were of varying length, some of them being looped over binding tapes.
This patent model demonstrates an invention for a typesetting machine which was granted patent number 174916. The type was stored vertically in channels, and was dropped piece by piece down converging tracks behind a glass panel, and assembled in a long line in a raceway at the bottom. The line was divided and space-fitted by a second operator. As with Lorenz's first patent, the rights were assigned indirectly to Henry Burr.
This patent model demonstrates an invention for a sheet-feed apparatus which was granted patent number 229998. The patent describes a feeding attachment for flatbed cylinder machines that allowed sheets to be held obliquely, so that bands of color could be printed diagonally across the paper-a style popular at the time.
This patent model demonstrates an invention for two hinged plates representing the platen of the Gordon press and the shaft below it, on which the guides were mounted; the invention was granted patent number 111304.
This patent model demonstrates an invention for a platen printing press which was granted patent number 87185. The patent covered various improvements on the inventor's earlier Universal press, a popular platen jobber in which the platen had a parallel approach to the bed. Merritt Gaily (born 1838) was apprenticed to a printer at 11, and he built a cylinder and a platen press while in his teens. In 1869 he set up a factory to build his new Universal press.
This patent model demonstrates an invention for a rest for an ink roller which was granted patent number 166675. The patent covered a simple rest attached to the inking plate on a small hand press, to support the handle of a hand roller. When not in use, the support could be stored under the plate. Patentee James Cook was the inventor and manufacturer of two amateur presses, the Enterprise and the Victor.
This patent model demonstrates an invention for improvement in stop-cylinder presses which was granted number 139229. The patent relates to the method of stopping and starting the cylinder, feeding and delivering paper, and distributing ink. The press could have two or more printing surfaces and stops on the cylinder, giving multiple impressions for each full revolution. Henry Barth was one of the owners of the Cincinnati Type Foundry. He was later famous for the Barth Type Caster.
This patent model demonstrates an invention for mechanical quoins, which expanded by means of paired screw gears; the invention was granted patent number 93603.
This patent model demonstrates an invention for a pen-ruling machine which was granted patent number 148381. The patent details an apparatus for arranging all the cams operating the pen bar and stop gate on a hub to the side of the pen cylinder, for quick access and adjustment.
