My girlfriend was cleaning up an old building in Pittsburgh and stumbled upon a Domestic Vacuum Cleaner Co. Worcester Massachusetts PAT'D. Nov.22.1910, Jan.7.1913. This thing is in fantastic shape. Prior to electric push vacuums. It's made of solid oak with lacquer. If you know anything about what i'm talking about please feel free to send me any information you have.
There is a gold circle with a picture of what seems to be a push vacuum that says "MANNFD. AND LICENSED UNDER Quest and Blanch Patents, Nov 22, 1910-Jan 7, 1913. Kenney Patent #847947 Mar 19, 1907
