Trammel
2 of the 6 encyclopedias on this shelf carry an entry for Trammel. Both are reproduced below, so you can see where they agree and where they differ.
The Encyclopedia of Founding (1892)
Compass-points attached to sleeves which slide on a bar or beam. They are used for describing larger circles than an ordinary compass will reach. They are held fast at any point on the bar by a set-screw on the top. Tramping, or Treading, is a method of ramming which, when thoroughly understood, is of great value to the moulder, owing to the fact that upon an equal thickness of sand a man's weight applied at every portion must result in an equal depression all over, and thus produce a rammed surface of equal density at every part. Tramping is much practised by light-work moulders, who roll all their work over in frame nowels with follow and bottom boards, as well as by those employed on heavy work, when mould-beds are formed in the floor. If this operation is not performed with judgment and care, the casting will most assuredly betray the moulder's ignorance or neglect; alternate heavy and light treading being unmistakably revealed by the undulating appearance of the casting's surface. A swelled casting is an abomination, but it may always be avoided by intelligent ramming and tramping. See RAMMING; VENTING.
Collier's New Encyclopedia (1921)
PARK, a United States senator; born in Macon co., Alabama, in 1876. As a child he was taken to Florida by his parents, where he attended the public schools until 15, when he became, first, clerk, then bookkeeper, in a store in Tampa, Fla. He studied law at Cumberland University, in Tennessee, and was admitted to the bar in 1899. In 1900 he was elected Democratic mayor of Lakeland, Fla., and in 1903 he was elected to the Florida House of Representatives, then to the State Senate two years later. During 1909-1913 he was attorney-general of Florida. In 1913 he was elected governor for a term of four years. In 1917 he was sent to the United States Senate for the term 1917-1923.
What Has Changed in the Last Century
The Encyclopedia of Founding's 1892 description of trammel points, compass legs sliding on a beam and locked with a set-screw, still describes a tool you can buy today, though the moulding-shop practice of tramping sand by foot that it discusses alongside has largely vanished with mechanised moulding and CNC pattern work. The other entry is a different subject entirely: Park Trammell, whose name is usually spelled with two Ls. When Collier's wrote in 1921 he had just begun his first Senate term; he was returned three more times and died in office on 8 May 1936, having served Florida as senator for nineteen years.
