It must be practically dust and waterproof and unbreakable, simple in construction, but of high effi-ciency; in fact, constructed specially for this kind of Stow Manufacturing Company, of Binghamton, has beenworking along this line for years, some of its earlier designshaving been previously illustrated in these columns. Several ofthe more primitive type have been in active service for the pastfour years, and are still in good working order, but practical usehas from time to time developed faults in construction which, asfast as discovered, have been corrected. The invention of the. AUTOMATIC TRACK DRILL PRESS multi-speed motor has aided greatly in perfecting this apparatus,and while no doubt further improvements will suggest themselves,the company has no hesitation in stating that in its present formthe combination of Stow flexible shaft and iron clad electric motoris as near fool proof as any electrical device on the market, andthat no appliance used in street railway construction will pay alarger dividend than this. The cut showing a cross section of the motor illustrates theextreme simplicity of its construction, and also the method ofspeed regulation. By simply raising and lowering the soft ironplunger in the hollow field by means of the hand wheel on top ofthe motor, the speed can be varied even to the fraction of a revo-lution. The motor is self contained, no outside speed regulatoror starting box being required, a most desirable quality in aportable motor. The automatic track drill press is a most valuable tool to usefor rebonding. As shown in the illustr
