9. Bevel-gearing. This is an adaptation of the spur-wheel principle to the case of non-parallel axes.

10. A worm or endless screw geared with a worm wheel.

11. Elliptical spur-gearing, used when a rotary motion of varying speed is required.

12. A spur-wheel geared internally with a pinion. The wheels rotate in the same direction (cf. 7).

13. Spur-gearing with oblique teeth, giving a more continuous bearing than 7.

14. Showing the transmission of power by rolling contact from one shaft to another obliquely situated with regard to it.

15. Different kinds of gearing for transmitting motion from one shaft to another arranged obliquely to it.

16. Two kinds of universal joints.

17. A method of transmitting motion from one shaft (the vertical) to another (the horizontal) by means of bevel-gearing, with a double-clutch for altering the direction of rotation. The bevel-wheels on the horizontal shaft are loose, and the direction of movement is determined by the side upon which the double-clutch is engaged. The clutch slides upon a key or feather fixed on the shaft.
