Invincible shaper shown in the photographs. Thismachine, by the way, will be exhibited at the mechanicalconventions at Atlantic City. Eight changes of speed maybe obtained for every change in stroke. Some idea of the]5ropartions of the gear box and the motor and of the rela-tive location of the control levers and wheel on the operatorsside of the machine may be obtained from tlie (Left) Operators Side of Machine Showing Application of Molor and Seleolive Type Gear Box. (Right) Partial Rear View. RAILWAY MECHANICAL EXGINEER Vol. 93, No. 6 The shaper has a range of cutting strokes of from 9 to maximum stroke is 28*4 m- and it planes for a widthof 29 in. The maximum distance from the table to the ram is l/j.^ in., and the minimum distance is 4J4 in- The headhas a vertical movement of S in., while the table has a similarmovement of in. AN OIL CONSERVER FOR BEARINGS AN improvement in the application of oil wipers for bear-ings is .shown in the illustration. It consists of a tem-pered steel spring with a triangular shaped piece of bab-bit metal mounted on the end. The babbitt is shaped to theshaft and wipes the shaft clean, returning the oil to the reser-voir of the bearing. The spring is fastened to a convenientpoint in the groove at the end of the bearing or to the wiper is placed at each end, and it is stated tha
