The engineer's sketch-book of mechanical movements, devices, appliances, contrivances and details employed in the design and construction of machinery for every purpose

by Thomas Walter Barber

[1292]. Reversible driving motion by single belt, with quick and slow motions; a modification of the last.

[1293]. By double clutch and bevil gear.

[1294]. Reversing friction cones or bevils.

[1295]. Three-wheel gear. The driving wheel A can be put into gear either with the driven wheel C or idle wheel B.

[1296]. Double clutch and spur gear reversing motion, with idle wheel.

[1297]. Reversing pinions, as used on the ordinary screw-cutting lathe. There are many varieties of this gear in use.

[1298]. Application of single belt gear to [No. 1296].

[1299]. Self-reversing gear, with one belt, two fast and one loose pulleys. The large spur wheel is driven from the bevil gear, and carries the weighted lever past the vertical position by a stop on the face-plate or disc, when it falls over and reverses the belt fork. See [No. 1026].
