Information needed

Thanks Why?Town, but what confuses me is the plate I illistrated says Youngstown. Could it have been a branch for the company?

I know that there were a number of businesses that manufactured radio equipment here during that time frame such as the Astetic microphone that was manufactured by the company that owned the Ross Radio Company, with their plant on Market Street, but never heard of Claravox until I stumbled on it at eBay.

It seems that CLaravox was a Canton business and MR Semple of Youngstown invented a loudspeaker which was patented through them..

Here's a link to the patent:

Can anyone help me identify a Youngstown business that was located here in the 1920's? The name of the business was Claravox Company of Youngstown, Ohio, or a Charles Simple, Jr. who was associated with the business.
