It is true that the cam, instead of being placed at the top of the stem, on the outside of the faucet, as was done by Bartholomew, is placed at its lower extremity, by the valve, inside of the faucet ”

“ Self-closing cocks and faucets were no new thing in June, 1865, when the patent of Jenkins was issued. Bartholomew had manufactured and sold them for a period of 10 or 15 years before that time. As early as 1854 he had made and sold faucets in which the valve was kept on its seat by the pressure of a spiral spring, and when a flow of water was desired, the valve was lifted from its seat against the force of the spring by means of a stem, operated by a collar of cross-piece moving around on a fixed circular inclined plane or cam, having the same effect as a screw ”
