Electrical news and engineering . a reduced cost for lightbills, and at the same time removed manj- of the defects fromnaked lighting. This, he said, was one of the livest subjectshe had found in his experiences in the east, and he lookedon it as one of the greatest fields for the practical electricalengineer to-day. THE ELECTRICAL NEWS 51 The Latest Developments inElectrical Equipment A Pump That Handles Semi-solids Tlu choking of pumps operating on scmi-soliils is anunpleasant experience with whicli most engineers arefamiliar and the consequent cost of removing the obstruc-tion, the burning out of motors in electrically driven pumpsand the slipping and burning of belts in belt operated in-stallations, are serious items which pump manufacturershave long (been endeavoring to eliminate. The Unchoke-able Pump, Limited, of London, England, whose Canadianagents are Jones & Glassco of Montreal and Toron-to (Bank of Hamilton Building.) have made these pro-blems their special study and as a result of many experi-. Fig. 1 nicnts have evolved a type of pump which tlicy claim en-sures that whatever is capable of passing through the suc-tion must be swallowed and discharged, and handled in abetter and more economical manner than could be the casewhen hand labor is employed. The Unchokeable Pumpis constructed to withstand the work inseparable from theconstant pumping of sludge, fibres, semi-solid and solidmatter, in principle the pump operates upon ordinarycentrifugal lines but in internal detail it differs from anyother. No screens are necessary, for large objects thatpass through the suction are ejected at the delivery. It isparticularly designed to pass unscreened sewage, rags, cot-ton waste, fibre and all kinds of pulp and trade effluent
