Only very few were ever built, the machine offered here has serial number G209 and powers an early high frequency cold-cathode ion-X-ray-tube with auto-regeneration invented by Henry Lyman Sayen and patented in 1897, just two years after Wilhelm Conrad Röntgen discovered X-rays on November 8 1895. X-rays were also called Röntgen-rays to honor its inventor.
Most early X-ray machines utilized induction coils powered by direct current to create the high tension needed to create X-rays. The Vulcan Coil offered here is powered by 110 Volts alternating current and uses a special coil which was patented by Seeley on October 19, 1915.
Little was known about the danger of X-rays at the time; radiologists taking X-rays of patients did not protect themselves from the harmful radiation and many suffered greatly and died young.
Today X-ray technology is so advanced that natural radiation is not much greater than having taken a diagnostic X-ray from a radiologist or dentist. Read more>>
