In either case the motor is located on theinclined ways on the opposite sido of the head from the boringspindle which it drives.

In this way the relative locations and principaldimensions of the drive arc not altered. The effect of this design of drive is to make a much morecompact arrangement than is usual where the motor is locatedelsewhere on the head. An idea of the neatness and simplic-ity effected by this arrangement may be gained from referenceto the 84-in. motor-driven quartfring machine In use at the Col-linwood shops of the Lake Shoie & Michigan Southern, which. A NEVy DESIGN OF ELECTRIC PRIVINCl FOR A QUARTERING MACHINE. DRIVEN BY A CONSTANT-SPEED CROCKER-WHEELER MOTOR UPON EACH HEAD. north of Mexico City. In these new shops, which are notablefor the use in their power plant of De Laval steam turbinesdriving Milwaukee direct-current generators, generous pro-vision has been made for the use of electric driving. A three-wire system of distribution is delivering 250 volts for light-ing circuits and 500 volts for power for operating the interesting motor driving equipments are to be installed,of which this outfit is representative. The machine is driven individually at each head by motors built by the Crocker-Wheeler Company,Ampere, N. J. The mountings for the drives are unusuallyinteresting. Each motor rests upon a triangular-shaped block,arranged to slide on the inclined ways of the heads. Thisblock also, by means of an extended sleeve, serves as a bearingsuppo
