IX. mi: 72 IiNcii WHEEL LATHE. In this article the discussion of the motor equipments forlathes at the McKees Rocks shops will be concluded by a de-scription of the motor-driving application to the 72-inch Nllesdriving wheel lathe which had been used at the old engravings, Figs. 44 and 45, illustrate this old lathe asilius equipped with the Crocker-Wheeler multiple-voltage sys-tem for variable speed driving. This drive involves the im-portant point of difference from the other drives previouslydiscussed in this series, in that here a back-geared type ofmotor is [Q, ll. ■VIEW 01 THE WHEEL LATHE AT THE MCKEES HOCKS SHOPS,AS CHANGED FOR THE INDIVIDUAL DRIVE. develops 25 at 240 volts, is used to drive this tool, in con-nection with a type 80-M. controller, for obtaining thevariable speeds available with the multiple-voltage system. Referring to Fig. 45 it will be noted that the_ controller isplaced on its side, on the lioor, and thai it is operated througha long extension shaft which is coupled to it and can be turnedfrom either one of two handles. The extension shaft is car-ried underneath the projecting part of the bed casting and isentirely out of the way of the operator. One controller handleis placed near each face plate, as shown in view; this ar-rangement is very convenient when hard spots appear on oneof the tires and it is necessary for the operator to slow up orstop, as a handle is always within easy reaching vertical castiron brackets, each of which supports the ex-t
