Only about 2000 of the almost 10000 X-patent documents were recovered.

Because of the Patent Office fire in Dec. 1836, little is known about this patent. There are no patent drawings available. This patent is in the database for reference only. Specification of a patent for an improvement in the art of Cutting and Casting Music Type. Granted to George B. Lothian, City of New York, August 11, 1830. The staff lines are fitted on single bodies, and dress up to the face on the extreme edge of the body, leaving no shoulder. What I claim as new, and my own invention and discovery in the above described type, and for the use of which I ask an exclusive privilege, is: In cutting and casting but one staff line on the time marks, thus they are, therefore, as readily made to line as a plain staff line. The type thus cast projects nearly one-half over the body, and fits on to the plain staff lines, above and below. In cutting and casting the angular quavers without any projection over the body, and a line, thus —, or an angle thus, i— or thus —i, is cast on a body equal to an entire quadrate, or half the size of the body of the staff lines, which is placed in the composing stick first, and then the quaver on it, which causes the quaver to run on the next line below, thus. An en quadrate or character on the half body is placed next in the composing stick, and makes up the two lines. The notes in the lines are made in the common manner; as also seconds, thirds, and choosing notes, and make perfect joining in the stems of the notes, without kerning, or projecting over the body. The slurs are cut and cast in the spaces of the staff, and come on the body without projecting. This improvement reduces the number of sorts in a fount, and facilitates the manufacture. George B. Lothian.
