Halfway up the shining surface of the gilt-framed pier glass was a mark a tiny ink-line that had been carefully drawn across the outer edge of the wide bevel. As Gwendolyn stared at the line, the reflection of her small face in the mirror grew suddenly all white, as if some rude hand had reached out and brushed away the pink from cheeks and lips.
Working through the groove, and projecting from the centre of the angle of the fork, is a lance of perfect form, sharpened with a fine bevel. Beside it the most perfect lance looks like a handsaw. On either side of this lance two saws are arranged, with the points fine and sharp, and the teeth well-defined and keen. The backs of these saws play against the lance.
In the second place, watch-glasses are ground on the edge to a single bevel to snap into the bezel or frame; but the edge of this object was ground to a double bevel, like the edge of a spectacle-glass, which fits into a groove in the frame and is held by the side-bar screw. The inevitable inference was that this was a spectacle-glass.
As this process of sharpening tools is a very important one, it must be reserved for another place. Should tools be seriously blunted or broken they must be reground. This can be done by the carver, either on a grindstone or a piece of gritty York stone, care being taken to repeat the original bevel; or they may be sent to a tool shop where they are in the habit of grinding carving tools.
"Level, perhaps, you mean, ma'am?" "Level or bevel,'it doesn't much diversify but I prefer the bevel to the level on all occasions. All I knows is," she proceeded, "that it is a shame for any young lady, as is a young lady, to take a liking to a Papist, because we know the Papists are all rebel; and would cut our throats, only for the protection of our generous and merciful laws."
At the forward end of the crankshaft there is mounted a master bevel gear on six splines; this bevel floats on the splines against a ball thrust bearing, and, in turn, the thrust is taken by the crank case cover. A stuffing box prevents the loss of lubricant out of the front end of the crank chamber, and an oil thrower ring serves a similar purpose at the propeller end of the crank chamber.
With his axe, the edge beautifully ground and sharpened to a razor-like finish, he could trim a piece of wood, or shape it, so neatly that it presented almost the appearance of having been planed; his saw, with no apparent effort, raced from end to end of a board or across the grain of a piece of "quartering," and his chisels and plane irons were ground to the correct concave bevel that relieves the parting of a chip or shaving, and gives what he called "sweetness" to the cutting action.
But they had white teeth and beautiful hair then, and loved 'Liberty, Equality, and Fraternity. Ha! ha! poor Bevel! poor Annette! Now they are going to repent, though they were good patriots then; I believe God will pardon them." He laughed as he recalled these old stories, but when we had reached the steps of the church he grew sober, and said: "Yes yes everything changes, everything!
With a motor speed of 1,450 r.p.m., the vertical shaft at the forward end of the motor turns at 2,175 r.p.m., this being the speed of the two magnetos and the water pump. The lower vertical shaft bevel gear and the magneto driving gear are made integral with the vertical driving shaft, which is carried in plain bearings in an aluminium housing.
These fly apart when caused to revolve by the bevel wheel gearing BB, and raise the sleeve S to a greater or lesser extent.
