INVENTION AND DISCOVERY.

TYPEWRITER FOR BOOKS.--We have for years had typewriters that would

write on loose pages of paper, but the making of a perfect machine that

could write in bound volumes has not been successfully accomplished

until the present time.

A typewriting machine can write much more quickly than any penman--and

the work it does has the advantage of being easy to read, whereas very

few people write a clear and legible hand.

In office work much of the writing to be done is making entries in books

and copying into ledgers.

All this has had to be done by hand, and it has of course taken a much

longer time to do.

By means of this new invention books can be kept and entries copied with

the same neatness and speed of an ordinary typewriter.

The great difficulty in making a machine to do this work properly was

that it was not possible to have the paper move back and forth as it

does in typewriting machines generally. For bound books the paper must

remain still, and the type moves over the page in the same manner that

the pen does.

The new book typewriter has mastered this difficulty. The page is held

firmly in a kind of frame, and the type moves with each letter or word

that it writes.

In making entries in books, it is highly necessary to be sure that the

writing is correct--and so this machine has a simple little device which

lifts the type up and shows the writing underneath.
