Wide were jumped downward from it in the intended plane; this prevented a skew fracture (PT.
Teeth of Skew-Bevel Wheels.The crests of the teeth of a skew-bevel wheel are parallel to the generating straight line of the hyperboloidal pitch-surface; and the transverse sections of the teeth at a given pitch-circle are similar to those of the teeth of a bevelwheel whose pitch surface is a cone touching the hyperboloidal surface at the given circle.
By its aid, for example, the whole of the properties a elliptical arches, whether square or skew, whether level or sloping in their span, are at once deduced by projection from those of symmetrical circular arches, and the properties of ellipsoidal and ellipticconoidal domes from those of hemispherical and circular-conoidal domes; and the figures of arches fitted to resist the thrust of earth, which is less horizontally than vertically in a certain given ratio, can be deduced by a projection from those of arches fitted to resist the thrust of a liquid, which is of equal intensity, horizontally and vertically.
Sliding Cont?,zct (lateral): Skew-Bevel Wheels.An hyperboloid of revolution is a surface resembling a sheaf or a dice box, generated by the rotation of a straight iAn line round an axis from which it is at a constant distance, - c and to which it is inclined at -~- a constant angle.
In skew-bevel wheels the properties of a line of connection are not possessed by every line traversing the line of contact, but only by every line traversing the line of contact at right angles.
