PUSH-BAR ELEVATORS AND CONVEYORS 351 These drag conveyors are built with very long are not usually reversible, although two-waytravel is sometimes provided for. The chief advantageof such equipment is its extreme simplicity of designand construction. It can be easily taken down andset up to meet changing layouts. Such a conveyor isused more for temporary service than for permanentinstallations. Cable carriers are often used for thispurpose instead of chain. For handling logs V-shaped troughs of 2 in. boardsare usual, while flat runways are used for ice, hay, andsimilar packages. The two sides of the V-trough formguards as well as sliding surfaces, keeping the packagemoving properly. With the usualflat runways side strips attached to the timber frame. With push-barsspaced about 4 ft. apart the capacity is very high, evenat the fairly low speeds of from SO ft. to 75 ft. per which such conveyors are usually operated. Inter-. The Drag Is the Simplest Conveyor guards are essential. In the lumber conveyors plaindetachable link chain with lug attachments propel thepackages. Where the wood push-bar is used, with theflat runway, particular attention should be given tosecuring it rigidly to the chain, for in operating a veryhigh strain comes on this point of attachment. Withthis type conveyor there is a tendency for the push-barto turn back as well as to twist sideways in drivingthe package ahead. Ice Cutting and ManufactureIce The push-bar conveyor has probably been more usedfor the handling of ice than for any other commodity,largely because it is the type conveyor most adaptedto such a light article and one that slides so of the simple construction of this conveyorit is less aflfected by being continuously exposed to theweather
