Numerous forms of friction clutches are in use, modifications chiefly of [Nos. 38], [59], and [282]. See also [Section 5].

Section 16.—COUPLINGS FOR SHAFTING.
[288]. Ordinary flanged coupling, usually made so that the end of the shaft forms a spigot joint with the opposite half of clutch.
[289], [290], [291]. Sleeve couplings. See also [No. 1430] and [Section 57]. Butler’s patent frictional coupling, Kirkstall Forge Co., Leeds, Seller’s double-cone vice coupling, and others, are sleeve couplings.
| [292].Angle coupling on Dr. Hooke’s principle. | - | See also [Nos. 33, 34], and [732]. | |
| [293].Flexible angle coupling for light work. | |||
[294]. Flanged coupling, with cross feather or key. This plan gives great torsional strength, especially if the coupling flanges are forged solid with the shafts.
