From the September 2, 1868 New York Times:

“A German gentleman, advanced in years, named Franz Vester, at present a resident of Newark, recently obtained a patent for a safety-coffin, designed so as to provide a way of escape to those who might be buried during suspended animation, as is supposed may on occasions happen, particularly during the prevalence of epidemics. This invention consists of a coffin constructed similar to those now in use, except that it is a little higher, to allow of the free movement of the body; the top lid is moveable from head to breast, and in case of interment is left open, with a spring attached for closing the same; under the head is a receptacle for refreshments and restoratives. The most important part of the invention is a box about two feet square, resembling very much a chimney, with a cover and ornamental grave-work on the top. This box is of sufficient length to extend from the head of the coffin to about one foot above ground. The cover is fastened down by a catch on the inside, and cannot be unfastened from the outside. Just below the cover is a bell similar to those used on street railway cars, with a cord suspended, which, upon being pulled, sounds an alarm, and at the same time a spring throws the cover from the ‘chimney box.’ Then, if the person on the inside have sufficient strength, he or she can take hold of a rope suspended from near the top of the chimney-box, and, with the assistance of cleets nailed to the sides, ascend to the outer world; or otherwise the individual can rest at ease, munch his lunch, drink the wine, and ring the bell for the sexton to come and assist him out.

Yesterday afternoon Mr. Vester gave an exhibition of the working of this invention by being buried, and after more than an hour’s interment, resurrecting himself.”
