Inventor Richard Liebau resided in Watervliet, Albany county (FIPSloc=36001), New York state.

The patent cites three other patents up front:

  • a patent of George Westinghouse, with serial number 520039, filed 28 Sept 1909
  • a patent of Liebau's, serial number 545957, possibly file on the same date as this one
  • application of George Westinghouse, serial number 545854 possibly filed on the same date as this one. ("of even date herewith", a phrase without clear meaning now)

It involves something "embodied" in a fluid cushion device "adapted for use as a spring". The claims refer to "a cushion device", perhaps with a chamber and sliding parts around it and suction.

The application was filed 1910-02-15, then "renewed" 1913-02-15.

It was "devised primarily in connection with automobiles." (page 1)
