Railway mechanical engineer . ity of Construction method of deliver), together with the downwardly directingforce of the steam jets, it is stated, avoids fuel losses due tothe tine particles being swept above the arch by the action ofthe draft before being consumed. The continuous introduc-tion of the fuel is also claimed to be a decided advantagefrom an operating standpoint. Extreme care has been used in the design of this stoker toavoid all elements of weakness which have apeared in pastpractice. The flexibility of the arrangement provided by theuniversal couplings and slip joints makes it relatively easy toapply the standard design to the many varj-ing tjpes oflocomotives. Only 14 parts in the entire stoker have variabledimensions for different installations, the rest being standardfor all sizes and types of locomotives. Convenient Speed Indicating Device T HE new speed indicator No. 748, placed on the marketby the BrOT\Ti & Sharpe Manufacturing Company,Providence, R. I., is designed to determine accurately. Brown A. Sh,ir|,. Indicator No. 748 the revolutions of shaftings, motors, etc., in cither directionand measure iKrth high and low speeds equally well. The design of this indicator is new. It has few parts and issimple in ojjeration. Tlie readings are taken from one side ofthe indicator, which can be quickly set at zero for repeateduse. The indicator registers up to 5,000 revolutions by every5 , although speeds much faster than 5,000 be readily detennined. The two arrows on the face ofthe dial indicate the figures to use for the different directionsof rotation, eliminating any confusion. The figures showingtlirougii the small round windows on the dial read every 5revolutions direct. The small inside dial is quickly turned to0 for repeated by the knurled knob on the back of theindicator. The fibre handle is especially shaped to fit the hand andthe filire is an insulation electricity. The workingparts are enclosed in a heavi
