system has proved a practical success in America, it will doubtless find favour in other
countries for work under similar conditions. This plant was erected by the Jeffrey
Manufacturing Co., of Columbus, U.S.A., for the mines of the Logan Consolidated
Coal and Coke Co., at Matewan, W. Va., U.S.A.
Slaughter-House Conveyors.—A modification of this type of conveyor is used
for handling carcasses in slaughter-houses when the trough is dispensed with altogether.
A general view of such an appliance is shown in Fig. 89, whilst Fig. 90 shows the detail
of one of the driving terminals, and the construction of the conveyor itself. This
conveyor consists of a steel cable to which are connected at regular intervals two kinds
of attachments, the smaller one being for the purpose of driving the rope from the
terminal, whilst the larger and disc-shaped attachment is intended to engage and push
forward the trolleys from which the beef and pork are suspended.
The illustrations explain themselves. Such a plant is at work at the packing house
of John P. Squires & Co., Cambridge, Massachusetts, U.S.A., and was erected by the
Steel Cable Engineering Co., Boston, U.S.A.
