Elements of technology :. the sameplane, but form an angle with each other, the spur gearing al-ready described, is changed for teeth of a different this case, the hevel gearing is commonly employed, consist-ing of wheels which are frusta of cones, having their teeth cutobliquely, and converging toward the point where the apex ofthe cone would be situated. According as the relative magni-tude of the wheels varies, the angle of the pig^bevel must be different, so that the velocitiesof the wheels may be in the same proportionat both ends of their oblique sides or this purpose the faces of all the teethmust be directed to the point where the axesof the two wheels would meet. The bevelgearing is shown in Fig 6, and Fig. 12. * The spiral gear has been used at Waltham, Mass. and elsewhere, for aboutfifteen years, and is commonly considered here as the invention of MrWhite. Something analogous to it, under the name of Inclined Plane Wheels,was published in London, by Mr T. Sheldrake, in
