Scientific American, n.s., 17:3 (July 6, 1867)

2007-09-05 14:48:38 | LinkRecords
AN ARTICLE IN THE Scientific American gave the Milwaukee enterprise its start. The editors of this periodical, one of whom, A. E. Beach, was himself the inventor of a writing machine, made it their policy to stimulate all kinds of mechanical invention in the United States. In their issue for July 6, 1867, they published an account of a " type writing machine " which an Alabaman by the name of John Pratt had recently exhibited in England. This device carried all its types on a movable " solid electrotype plate." In front of this plate a vertical framework held a piece of paper and a " carbonized sheet," and a " minute hammer " striking the paper from behind knocked it against the carbon and one of the types to make the impression. After describing this machine of Pratt's, the Scientific American went on to say: "The subject of type writing is one of the interesting aspects of the near future." Writing was about to be revolutionized." the laborious and unsatisfactory performance of the pen must sooner or later become obsolete for general purposes," and the "weary process of learning penmanship in schools " must be " reduced to the acquirement of writing one's own signature and playing on the literary piano above described, or rather on its improved successors." These words came to the attention of C. Latham Sholes, and he got an inspiration from them.3

article, see ibid., 27:77 (Aug. 10, 1872).

nuisance of type-bar collisions

2007-09-05 14:37:02 | LinkRecords
Densmore was turning out machines one by one, not mass-producing them, and so he was able to incorporate changes in design as he went along. On some machines he put a treadle (a dubious "improvement") so that an operator could throw back the carriage by pressing his foot. To lessen the nuisance of type-bar collisions, which were frequent, largely because of the alphabetical order of the keys, he adopted a new arrangement that he and Sholes had worked out. This revision fixed, once and for all, the basic pattern for the present standard or " universal" keyboard.26

26 Sholes to "Walter J. Barron, June 9, 1872, facsimile in Reiley, Story of the Typewriter, 51; Sholes to Barron, Oct. 5, 1872; Densmore to Barron, Nov. 8, 1872; Densmore to Lavantia Douglass, Sept. 9, 1884; Quaife, Roby's Story, 67-69; Frederic Heath, " The Typewriter in Wisconsin," Wisconsin Magazine of History, 27:263ff (March, 1944).

The Original Typewriter Enterprise,1867-1873 Richard N. Current

AN ARTICLE IN THE Scientific American gave the Milwaukee
enterprise its start. The editors of this periodical, one of whom,
A. E. Beach, was himself the inventor of a writing machine, made
it their policy to stimulate all kinds of mechanical invention in
the United States. In their issue for July 6, 1867, they published
an account of a " type writing machine " which an Alabaman by
the name of John Pratt had recently exhibited in England. This
device carried all its types on a movable " solid electrotype plate."
In front of this plate a vertical framework held a piece of paper
and a " carbonized sheet," and a " minute hammer " striking the
paper from behind knocked it against the carbon and one of the
types to make the impression. After describing this machine of
Pratt's, the Scientific American went on to say: "The subject
of type writing is one of the interesting aspects of the near future."
Writing was about to be revolutionized―" the laborious and unsatisfactory
performance of the pen must sooner or later become
obsolete for general purposes," and the "weary process of learning
penmanship in schools " must be " reduced to the acquirement
of writing one's own signature and playing on the literary piano
above described, or rather on its improved successors."
