seller noteRare example of Aylsworth's 1905 Patent Ear Trumpet. An extremely rare example of A.W. Aylsworth's 1905 U.S. patent ear trumpet (No. 780,699), the patent for which was awarded on January 24, 1905. It is marked with patent date. Aylsworth's patent incorporates a spring-mounted diaphragm that extends into the base of the trumpet bell. The mechanism is shown in the patent drawing, a copy of which can be been in the second image. The actual diaphragm is visible in the third image. The bars on the sides of the tube are unquestionably original and prevent the internal spring from being bent to a point where it would affect the functioning of the diaphragm. More extensive information about the patent specifications can be easily obtained by entering the patent number at the US Patent Office Site or by simply Googling:'Ayslworth Ear Trumpet'. Length: 13.5in or 33.75 cm.We have been dealing in antique medical instruments, including ear trumpets, for more than three decades and this is the first example of an Aylsworth we have owned; more significantly, we cannot locate another example in any book, article or museum collection.
