Odin. Evolution of the Typewriter. (1917)
Odin, C. V. Evolution of the Typewriter. ([no location]: [by the author?], 1917)
A rather opinionated history of the typewriter from a Underwood salesman's point of view. It contains a number of line drawings of various machines (as well as a halftone frontispiece of its author). It is notable, however, both because it is an early attempt to chart the technical history of the typewriter through the identification of the invention of particular features and because it contains a series of diagrams explaining the keybar actions of several typewriters.
This book has been scanned by the US Library of Congress from their copy and is available via The Internet Archive. The icon above left links to that presentation. Here, mostly for my own convenience, are local copies of the PDF and DjVu format versions:
Odin's book contains numerous line drawing of typewriters (and, as noted, drawings of typewriter keybar actions and escapements). The Library of Congress scan at The Internet Archive contains their original page scans (saved lossily as JPEG-2000 (.jp2) images in a tar-format archive). These images are handy to have, so I've extracted them and converted them losslessly to PNG-format images. Each icon below links to one of these images. I've cropped them from the original page images, rotated them 90 or 180 degrees so that they're right-side-up (the scanning is done sideways), and saved the results losslessly as PNG image files. I have not done any other rotational adjustment or image enhancement - these are from the "raw" scans, and are not always squarely aligned. Some of them are a bit blurry as scanned. Click on any of the small images below for the full-resolution version. To save an image at full resolution, either do a "save link as" or click through to get the linked image and the save it. Don't just save the thumbnail image.
This book is in the public domain in the US due to the expiration of all possible copyright. The US Library of Congress' scan of it, and the re-presentations of those scans here, and the extracts from those scans re-presented here, remain in the public domain.
