Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1904 edition. Excerpt: ...100 and 101 modifications of the loose path are shown, in one of which (fig. 101) they are formed internally. The pressure of the superstructure of the crane upon the path is sufficient to keep it stationary when slewing or rotating under f ordinary conditions, but should the mechanism be suddenly stopped or started, the additional stress occasioned, instead of breaking the wheel teeth, or causing failure of some other part of the machine, as has so frequently happened where a fixed path is employed, would simply cause the loose path to revolve slightly upon its seat until the shock had spent itself. It will thus be seen that a loose roller path performs very much the same service for a crane that a safety valve does for a steam boiler. Under ordinary working conditions the loose roller path, like the safety valve, does not come into action; but so soon as any undue stress is brought upon the crane, the path yields, as the friction between it and its seating on the base plate is insufficient to resist anything beyond the ordinary stress of working. The loose path has also an advantage in that its occasional movement prevents the rollers from rubbing and wearing it in one place, or upon one small portion only, for in the majority of cases a crane is not often required to swing round in a complete circle, the chief work being confined to an angle of about 90 degrees; so that the path of a fixed crane will be quickly worn down in that one portion only, whilst the movement, in the case of a loose path, will cause the wearing to be equalised and distributed all round the ring; and further, a loose path can be readily renewed at any time, whereas the wearing down of a fixed path would in most cases mean a sacrifice of the whole bed or base...
