Page 69 - Stevens1 through the use of a bell metronome. A piece of white card-board is fastened to the instrument in such a way that the pendulum oscillates in front of it. The card-board presents the arc of a circle, the radius of which is equal to the length of the pendulum, scaled in 5° intervals. The position of objective coincidence of the bell-stroke and pendulum, may be ascertained as in Wundt's machine, by slowly moving the pendulum across the dial until the bell sounds. The method of Stevens...
Page 4 - F ; the other end of this rod is connected either directly with the valve-spindle or acts upon the one end of a lever, the other end of which is connected to the valve-spindle.
Page 3 - BD revolves within the ring EF, that ring, together with the arm LM, will be alternately driven, right and left, through a space equal to twice the distance between the centre of the eccentric and the centre of the revolving shaft. If we suppose a notch formed at the extremity of the arm LM, which is capable of embracing a lever NM, moveable on a pivot at...
Page 109 - The valve is shown with the opening for admitting steam sufficiently advanced to give the desired lead. The arc of the lever is constructed, as already mentioned, with a radius equal to the length of the eccentric rod, and in its present position the centre of the eccentric is also the centre of the arc. It will be plain, therefore, that the slide attached to the eccentric rod joint can pass from one end of the arc to the other without disturbing the lever or valve, and consequently with the lead...
