Any good anagrams for airpump?

n.s..

A machine by whose means the air is exhausted out of proper vessels. The principle on which it is built, is the elasticity of the air; as that on which the waterpump is founded, is on the gravity of the air. The invention of this curious instrument is ascribed to Otto de Guerick, consul of Magdebourg, who exhibited his first publick experiments before the emperour and the states of Germany, in
1654. But his machine laboured under several defects, in the force necessary to work it, which was very great, and the progress very slow; besides, it was to be kept under water, and allowed of no change of subjects for experiments. However, Mr. Boyle, with the assistance of Dr. Hooke, removed several of these inconveniencies; though, still, the working of this pump was laborious, by reason of the pressure of the atmosphere at every exsuction, after a vacuum was nearly obtained. This labour has been since removed by Mr. Hawksbee; who, by adding a second barrel and piston, to rise as the other fell, and fall as it rose, made the pressure of the atmosphere on the descending one, of as much service as it was of disservice in the ascending one. Vream made a further improvement in Hawksbee’s air-pump, by reducing the alternate motion of the hand and winch to a circular one. Ephraim Chambers
