THE RAY PULLEY COVERING. E\^ E R Y few months the mechanical world isstartled by some invention which, thoughapparently an absurdity on first inspection,proves to be a remarkably practical and efficient Walker differential cable drum is probably the mostprominent example of this. The pulley covering heredescribed is one of the same class of absurdities, whichwork so well in practice. It consists simply in wrappingthe pulley with ordinary bell or sash cord. In applyingthis covering the cord is kept from slipping off the edgeof the pulley rim by passing the cord under the rim atregular intervals on the convolution nearest the use of a slightly flanged pulley would obviate thenecessity of this. The drawings show it as applied to an. ordinary railway generator pulley. The invention is theproperty of Sol. Ray, chief engineer of the City ElectricCompany, Decatur, 111., and was evolved by the necessi-ties of the station, which was having continual troublewith the belts coming off its 90 kilowatt generatorpulleys. Every pulley covering on the market was triedwithout success, until Mr. Ray. in a fit of desperation,wound the pulley faces with bell cord as described, gavethe rope a good coat of pine tar, put on the belt andstarted up, with the result that there has been no troublesince. The covering has also been tried with success onseveral other large pulleys in Decatur. THE REVIEW HAS HORNS. THE Review has horns, and a very pretty set, too,the kind remembrance of Fred S. Wardwell,recently general manager of the Duluth streetrailway system. The horns are connected up properlyin series, and surmount a nicely mounted head, once thepossessor of a large and nimble body, probably an expertat rai
