The Kitchen Plan Book, 1920 Published by Hoosier Manufacturing (the cabinet people!) is available at the Internet Archive's online texts archive. It is a free download, or you can read it online. It's the collected best submissions from a kitchen design contest, and shows a fantastic variety of kitchens from classic mid-late 1910s bare-bones rooms with wood stoves to ultra-modern, deluxe, fitted kitchens that would not look out of place in a modern home.
Here are a few excerpts:
This one is for a small kitchen not unlike ours. I want built in everything, like this little kitchen has.
I especially love this one, though it's for a much more architecturally interesting house, with an octagonal kitchen. It looks like something you might find in a new house with a modern fitted kitchen.
Advice, if you want to download it: remove the extra periods from the filename, or your pdf reader will tell you it's a corrupted file.
If you want to get a hard copy of an earlier one, American Bungelow has their reprint of the 1917 edition of the Kitchen Plan Book (all different designs from this one, different year's contest) on sale, half price.
