“A, Plate 9, fig. 4, (of this Work) is a circular inclined plane, moving on a pivot under it, and carrying round with it the axis E. A person walking on this plane at A, and pre...
1. Part 1Depending on the hard- and software used to read this text, not all characters may display properly or at all. The alignment of the tables may depend on the font used.
2. Part 2If it were now desired to find the power of a man turning a crank or handle, we should take that given in the figure 12, and fix it to the power-axis A. We should also take the...
8. Part 8Figure 2 of the present Plate, represents the plan of the Machine, but turned upside down; so that the feet _G H_ screwed _under_ the lower plate _E F_, are wholly visible. In t...
3. Part 3To this account of the result of these experiments, I beg leave to add what seems to be a great improvement of this System: namely, a method by which the diameters of the larger...
10. Part 10It so happens that many of my Inventions are of a generic nature, and thus apply to cases which, appearing different, have nevertheless some common properties. The _rule of cont...
9. Part 9“_C D_, in this same figure, presents another form of the head and stern of two contiguous Boats or _parts_; (which, to save room, are both supposed to be _broken off_ at some p...
15. Part 151st.--These objects are dropped into the vessel as soon as produced, and the vessel is filled, one half or more, with cold water from the reservoir _F G_. The things are then le...
17. Part 17But to make this important piece of the Machine better known, I have drawn it apart, in figure 4, on the _supposition_--that it is a portion of _a cone instead of a sphere_: I s...
16. Part 16This Plate _k l m n_, is no other than that marked _o p_ in fig. 2; and it is there fixed to the index _a b_, directed to the central pin _C D_, as it is in fig. 1 to the centre...
20. Part 20To come to the point:--the small figure 4, in Plate 41, relates to this subject. My geering is there seen in three forms or applications--each one intended to bring the above pr...
12. Part 12Plate 23, gives in fig. 3 and 4, a representation of this Machine; _A B_ and _C D_, are two _slides_, having wedge-formed ends above _A_ and below _D_, well made, well steeled,...
13. Part 13The figures 2 and 3, are two views of the upper part of the Machine. They shew, and mark with the same letters, the cross bar _a b_, the inside of the screws, and the circular p...
21. Part 21I therefore, say nothing more of this Instrument as a pendulum: but an inspection of the figure will shew, that it will not be useless as an ELIPSOGRAPH--which it clearly is, si...
19. Part 19We come, then, to it’s motion in the slide. _p r_ shews a wheel, running loosely on the axis of the porte-outil; and having fixed to it a concentric rim _r_, with _three or four...
5. Part 5This Machine is among the first inventions I carried into real practice on coming to manhood. It must be about 40 years ago, and was first constructed as a Crane at the request...
11. Part 11In Plate 21 fig. 4, there is a representation of this Instrument. It is composed of a frame _A B_, containing a strong shaft _C D_, on which are placed the three following objec...
14. Part 14When, therefore, a pulling bar, a crank and fly, or any other prime mover, applied at the joint _a_, carries that joint (say) toward the pillar _D_, that motion takes place with...
6. Part 6Before I proceed to the particular description of my own wheels, I shall point out one striking defect of the system now in use, without reverting to the period when mechanical...
7. Part 7On the right of the drawing, (fig. 6) the teeth of the wheel _B_ are angular, (suppose square) and those of the wheel _C_ rounded off by any curve _s_, _within_ an epicycloid. A...
18. Part 18But we have another important property to speak of. The colours on the two cylinders must be _fitted in_, laterally, as well as longitudinally: and the Machine performs this by...
22. Part 22This Machine (see Plate 49, fig. 1,) is capable of great results _merely because it employs, at a small expence, a great mass of air in motion_; whether _ill_ or _well_, is not...
