This patent model demonstrates an invention for a web perfecting rotary press which was granted patent number 468. Flat forms of type were arranged around the surface of two type cylinders to form polygons. The web of paper was printed on both sides at this press, then sent to a drying machine still in the web, and finally cut into sheets. The inventor is named "Trench" on the patent drawings and "French" on the specification.
This patent model demonstrates an invention for a machine which produced type by compression and cutting from rods of any metal; the invention was granted patent number 5049. The face was formed using a steel letter matrix or, for reversed type (type en creux), a steel punch. The model is a full-sized working machine. (Jean Petyt was from Paris, France.)
This patent model demonstrates an invention for printing directly on glass or metal with elastic type instead of using the common practice of stenciling on the surface or using a paper label. The invention was granted patent number 56593. The rubber printing block of the patent model has hardened and perished. In 1860 Isaac Miles had bought shares in the rights of two other printing patents: Samuel Lowe's cone press (Patent 15429, 1856) and Charles Hawkes's platen press (Patent 7855, 1850).
This patent model demonstrates an invention for the first of a generation of fast web perfecting presses which was granted patent number 38200. On this press, unlike its successors, the paper was cut into sheets before being printed. According to Stephen D. Tucker’s History of R. Hoe & Company, the web cutting knife had been used years before on a Hoe press, but the concept had not been patented.
This patent model demonstrates an invention for a book-stitching machine which was granted patent number 150495. The machine includes a mechanism to protect needles in book-sewing machines: latches to hold the needles in position and an alarm bell to warn of approaching knots in the thread. Thompson was an inventor and manufacturer in the field of book stitching, stapling and sewing machines who also acquired interests in the inventions of others.
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 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 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 an engraving pantograph, particularly intended for cutting letters from a pattern into stone; the invention was granted patent number 27827. The graver was provided with a rotating and/or a pecking motion.
This patent model demonstrates an invention for a portable and adjustable copy holder on which the reader could tilt the manuscript backwards or spin it sideways, "with reference to light, etc., to suit himself." The invention was granted patent number 155202. Nutting (1803-1887) was one of the first generation of American lithographers, working at the profession as early as 1826. Later in his life he was also an art teacher, and published a series of art teaching manuals.
This patent model demonstrates an invention for an electrotype shell and base which was granted patent model 313812. The patent describes a method of fastening thin electrotype shells to cast metal bases by bending the edges of the shell into grooves on the base. The invention was said to be particularly appropriate for newspapers, which might otherwise depend on heavy stereotype plates shipped over long distances. The patent was assigned to the American Press Association.
This patent model demonstrates an invention for a machine with a pair of divided rolls, or roll segments, to shape book backs. The invention was granted patent number 25548. G.H. Sanborn (d. 1881) established his reputation and his company with his rounding machine and went on to develop and sell a full line of equipment for bookbinders.
This patent model demonstrates an invention for a casting printers’ lead; it was granted patent number 155609. Molten lead was rolled out to thickness between two flexible steel belts, then cut into strips, trimmed, and planed smooth.
This patent model demonstrates an invention for a piston-driven stencil-cutting pen which was granted patent number 216086. The piston was driven by a bellows powered in turn by a machine wheel. Josiah Gunning (1840-1910) graduated from medical school and spent the Civil War as a surgeon in the U.S. Navy. After his wife's death in 1869, he entered seminary and was ordained. His invention of a pulsating pen was considered remarkable enough to win him a bronze medal from the American Institute.
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 self-inking platen jobbing press with a vertical bed and platen which was brought together by toggle levers. An inking cylinder sat beneath the bed, and a frisket frame was lifted up between impressions to receive sheets of paper. The invention was granted patent number 3716. This invention first appeared as Gilman's job press, and then from 1846 to 1873 as the Hoe Company's Patent Machine Card Press.
This patent model demonstrates an invention for an apparatus that delivers sheets printed side up, without risk of smudging when fresh ink came into contact with delivery tapes; the invention was granted patent number 221458.
