Side 174 - Mr. Saxton of Philadelphia, now in London, who is justly celebrated for his excessively acute feeling of the nature and value of accuracy in mechanism ; and who is reputed not to be excelled by any man in Europe or America for exquisite nicety of workmanship...

Side 172 - ... tooth, at the primitive circle (pitch-circle), and with the other point describe a segment of a circle for the off side of the next tooth. . . . Others set the point of the compasses at different distances from the center of the tooth, nearer or farther off; also within or without the line of centers, each according to some inexplicable notion received from his grandfather or picked up by chance. It is said inexplicable, because no tooth bounded at the sides by segments of circles can work together...

The following, is his verbal description of this instrument. The wheel to be rounded being put on a vertical arbor, another arbor...
Side 119 - To find the numbers of the teeth and leaves of the wheels and pinions of a machine, which being moved by a pinion placed on the spindle of the minute wheel of a clock, shall cause a wheel to make a revolution in 29 days, 12 hours, 44 minutes, 3 seconds, and 12 thirds, which form a mean synodical revolution of the moon.

In a great number of repetitions of this experiment, a slight receding of sector N0. 2 sometimes appeared. EXPERIMENT VI. The teeth were engaged a quarter of an inch : the ends of the teeth, therefore, were one inch and a quarter from the bottoms of the spaces ; and the points of contact,...
Side 173 - ... true principles. We regret to learn, from the same authority, that there are many wheel-makers who follow no rule of proportion at all in their formation. "In Lancashire, they make the teeth of watch-wheels of what is called the bay-leaf pattern; they are formed altogether by the eye of the workman, and they would stare at you for a simpleton, to hear you talk about the epicycloidal curve.
Side 143 - ... have been so misled by this misconception of the original translator of Camus, that they are daily ''pouring into the market multitudes of cast-iron wheels and pinions, of various magnitudes, for cotton and other machinery, with teeth formed from the epicycloid of the diameter, instead of the radius of the opposite wheel, or pinion,
