CONVEYORS.

[1080] & [1081]. Wood troughs sometimes lined with metal.

For conveying materials other than liquids, such as sand, coal, grain, &c., the following contrivances are used:—

Endless bands of canvas, rubber, leather, &c., sometimes with flanges like [1082].

Sloping wooden tubes or shoots.

[1082]. Sectional conveyor, endless, carried round pulleys like [No. 1083].

[1083]. Creeper, an endless chain of boards or buckets sliding along a fixed wood trough. See Ewart’s patent detachable drive chain, which is fitted with special links for attachment of boards or buckets.

[1084]. Worm and trough, similar in principle to an archimedean screw.

See [No. 1022].

Elevators for vertical or sloping conveyance usually consist of an endless band of some flexible material or chain with a number of tin or metal buckets attached at regular intervals (as [No. 1086]) like a creeper, [No. 1083], but working in an enclosed tube.
