This patent model demonstrates an invention for a typecasting machine which was granted patent number 4072. The patent details further developments on David Bruce's pivotal typecaster.
This patent model demonstrates an invention for a rotary and perfecting web press; the invention was granted patent number 169796. The rotary press has two type cylinders, two impression cylinders, and a knife to cut the sheet from the web of paper before the first impression was made.
Half the rights were assigned to Calvert B. Cottrell and Nathan Babcock, press builders, of Westerly, Rhode Island. Joseph Firm (born 1837) followed an interest in printing from his high school days. Apprenticed to Harper & Row and later employed by Frank Leslie, he was responsible for many patents and particularly concerned with large, fast presses. After 1892 he associated himself with the Goss Printing Press Company, which built some of his presses.
This patent model demonstrates an invention for a small self-inking card press which was granted patent number 17405. A traveling frame carried the inking and impression rollers across the fixed type bed and ink plate.
This patent model demonstrates an invention for a self-inking bench-top press for cards or sheets; the invention was granted patent number 24655. It was the basis for the Newburys' Mountain Jobber or Machine Jobber. Early models followed the patent closely, but later (about 1871) the press had a sloping ink disk. A. N. Kellogg produced a modification of the press, which he patented in 1863 (Patent 37293).
This patent model demonstrates an invention for a sheet perfecting flatbed cylinder press which was granted patent number 103894. The invention had two vertical type beds, one at each end of the press. A sheet of paper was fed to the first cylinder and printed at the first type form traveling upwards. Next the sheet was passed to the second cylinder and printed on the other side at the other form traveling downwards. Finally, it was deposited under the press.
This patent model demonstrates an invention for nippers, a sheet separator, and a fly, all designed to ensure that only one sheet could be fed to the press at a time; the invention was granted patent number 12702.
This patent model demonstrates an invention for a plate printing press which was granted patent number 193097. The press bed was pulled by a continuous chain along a four-sided track, with stations for the operations of inking, wiping, supplying paper, and printing. This patent improved upon Milligan's patent of 1876 (Patent 180490). In 1878 Milligan steam presses were installed in the Bureau of Engraving and Printing for printing tobacco stamps and the green backs of some bank notes, replacing hand presses. In 1889, as a result of protest from the Knights of Labor on behalf of copperplate printers, 19 steam presses were taken from the Bureau and replaced with 67 hand presses. After 1900, steam presses based on Milligan's pattern were gradually reintroduced to the Bureau. They were considered the Bureau's workhorses in the 20th century.
This patent model demonstrates an invention for a flatbed cylinder press which was granted patent number 18567. The press has a segmental impression cylinder, which rocked back and forth across the bed.
This patent model demonstrates an invention for a small, self-inking clockwork press that printed from curved stereotype plates; the invention was granted patent number 71103.
This tinted lithograph of “Mountains Near the Entrance of the Canada de las Uvas" was produced by Thomas Sinclair (1805-1881) after an original sketch by expedition artist Charles Koppel (fl. 1853-1865). It was printed as Plate VII in Volume V, Part I, following page 26, in the "General Report," part of the “Routes in California, to Connect with the Routes near the Thirty–Fifth and Thirty–Second Parallels, Explored by Lieutenant R. S. Williamson, Corps of Topographical Engineers, in 1853."
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 1856 by A. P. O. Nicholson (1808-1876) of Washington, D.C.
This tinted lithograph of “Lost Mountains in the Great Basin" was produced after an original sketch by expedition artist Charles Koppel (fl. 1853-1865). It was printed as Plate IX in Volume V, Part I, following page 26, in the "General Report," part of the “Routes in California, to Connect with the Routes near the Thirty–Fifth and Thirty–Second Parallels, Explored by Lieutenant R. S. Williamson, Corps of Topographical Engineers, in 1853."

This tinted lithograph of “The Great Basin from the Canada de Las Uvas with Lost Mountain in the Distance" was produced by A. Hoen & Company (fl. 1848-1943) Baltimore, after an original sketch by expedition artist Charles Koppel (fl. 1853-1865) after an original sketch by William P. Blake (1825-1810). It was printed as Plate VIII in Volume V, Part I, following page 26, in the "General Report," part of the “Routes in California, to Connect with the Routes near the Thirty–Fifth and Thirty–Second Parallels, Explored by Lieutenant R. S. Williamson, Corps of Topographical Engineers, in 1853."

This patent model demonstrates an invention for bank note printing which was granted patent number 41724. In the steel transfer process used for intaglio security printing, it was difficult to make a plate that was both soft enough to receive an impression and hard enough to resist distortion in the transfer process. By this invention, a hard steel plate was faced with a sheet of soft iron.
This patent model demonstrates an invention for a rotary perfecting press which was granted patent number 113769. The patent allows for separating and piling set-off sheets on perfecting presses, and providing easier access to the blankets on the second cylinder.
This patent model demonstrates an invention for an elliptical quoin, set between ordinary sidesticks and turned by a wrench to force the sticks apart; the invention was granted patent number 201075.
This patent model demonstrates an invention for a machine for dressing and finishing the four sides, the shoulders, and the edges of type; the invention was granted patent number 60450.
This patent model demonstrates an invention for improvements to the distribution, inking, and feeding apparatus on stop cylinder presses. The invention was granted patent number 178326.
This patent model demonstrates an invention for a stereotype pan for casting metal plates from plaster of Paris molds; the invention was granted patent number 10704.
