PNEUMATIC DRILL TESTER, OMAHA SHOPS, UNION PACIFIC RAILROAD. PNEUMATIC DRILL TESTER. In the September. 1907, issue of this journal, page 364, a pneu-matic drill tester was described in which the drill was arrangedto drive a fine thread screw, with a piston at its lower end, intoa cylinder partially filled with oil. The comparative value ofthe drill was judged by the pressure on the oil when it wasstalled. A more elaborate and satisfactory device, in use in the shopsof the Union Pacific Railroad at Omaha, is shown in the photo.The drill socket engages with the prony brake shaft and thebody of the drill is kept from revolving by the two arms project-ing from the work bench. The amount of air used by the drillis measured by the Excelsior Aerometer at the left, which wassupplied by G. D. Warren & Co., of Denver, Colo. An air gauge,not shown in the illustration, shows the air pressure. The speedof the drill may be determined by applying a speed indicator tothe rear end of the prony bra
