Henry P. Bridges Sound Producing Device Patent for first patented diaphragm issued Feb. 1, 1921

Entry/Object ID

VTC0020001

Description

Henry P. Bridges of Maryland would file a patent for a diaphragm turkey call on March 20, 1920. Patent 1,367,176 would be issued for his "Sound Producing Device" on February 1, 1921. Bridges would advertise his call in outdoor magazines, but we have unfortunately not verified one. This is not unexpected as it would have been a difficult call to keep for many seasons.
