I guess I began wondering about mechanical things as a kid, took apart the Bendix coaster brake on my first two-wheeler when I was seven. So, I investigated the mysteries of our bungalow's locks. Best example of a pic I could find below. The lockset was mounted in a slot in the center of the door. It was a flat squarish hunk about 4 X 4 X 3/4 inch thick, with holes on either side to allow insertion of a key. The keys all looked like the pic below, but not quite as exagerratedly large. Every door took a big, long, heavy key. No wonder my Mom was forever repairing holes in our pockets!
The doorknobs were fastened to a square steel rod by setscrews, the rod passing through the lockset in the door. Many of the doorknobs were made of glass, mostly clear, not colored. Occasionally, a doorknob loosened, and wiggled around, posing a repair job for the little snot who had to get into everything! In later years, I have wondered how my folks were able to cope with it!
Are these old type locks still in use in Berwyn's bungalows? berwynson
