    Questions
  • 4. Grave Alarm
  • 5. Grave Alarm
    • Bordering on the bizarre, the U.S. patents described here reflect a concern on the part of some that persons might be buried prematurely.
    • It was feared that the vital signs of persons in a coma or “suspended animation” would not be detected.
    • As embalming became more widespread, this concern became a moot point, except, perhaps, to the most gullible.
  • 6. Details
    • Patent number : 500072 Filing date : Feb 4, 1893 Issue date : Jun 20, 1893 Inventor : AUGUST LINDQUIST Assignee : F ONE
  • 7. The Patent
    • In 1893, a patent was granted to Adalbert Kwiatkowski, of Germany, for a coffin signal using a long spring loaded flag within a tube extending to the surface and a complex linkage with a bridle resting on the forehead of the corpse and ropes around the hands.
  • 8.  
  • 9. What is it about
    • The invention relates to improvements in Grave Alarms whereby the persons who are prematurely buried before life is extinct can sound an alarm thus notifying the cemetery officials of the fact
    • The object of the invention is not only to provide means of sounding alarm but also to provide improved construction whereby fresh air is supplied to person prematurely buried so that life can be sustained until help arrives.
  • 10. Working
    • When a coffin is lowered into a grave, and before the latter is filled in.
    • The tube 2 is connected with the coffin, and the lower end of pipe 5 inserted within the flange 4, and encircling side tube.
    • The tube 8 is then connected with tubes 2 by means of the bayonet joint and the lower end of pipe 16, engages over the upper end of pipe 5
    • The dirt or soil is then filled in as usual
    • It will be seen that the cord 15 extends down into the coffin, and in case the supposed corpse should have been in a trance and not dead, when regaining consciousness can grasp the cord and sound an alarm
  • 11.  
  • 12. Working - contd
    • At the same time fresh air will be admitted to the coffin through the tubes, whereby life may be sustained until help comes.
    • After a sufficient length of time has elapsed, so that it will be positively certain that death has taken place, the housing and the tube 6 can be disconnected from tube 2.
    • And hence the apparatus can be readily used again and again
  • 13. Conclusion
    • Though it is one of strange inventions it shows one human feeling the most which is
    • “ hope”
  • 14. Thank You “ Live in Peace”
  • 15. Review Questions
    • Grave Alarm is mainly for whom
