INV-24025.03 JAMES MADISON Document Signed as President, issued to Atkinson Farra, Patent for a double-bored pendulum pump. Washington, December 5, 1809. Co-signed by Robert Smith as Secretary of State. 1 p plus inventor’s 2 pp. description affixed by thin silk ribbon. 11˝ x 14˝ in. 1809-12-05

President James Madison issued this patent to Atkinson Farra of Pennsylvania. This double-bored wooden pump was operated by a pendulum handle, which caused the “suckers in each cylinder to play alternately; by operation of which the water flows without intermission.” Farra adds, “If it be necessary (as it may be in ships) to increase the force this may be done by adding another handle to be worked on the opposite side; it is also suggested by the inventor that the rods may be worked by mechanisms similar to a Clock.”
