ELECTRICALLY OPERATED FORGEROne of the most interesting applications isfound in the temporary structure which hasjust been erected as an addition to the black-smith shop for the large forging machinesshown in the accompanying cut, together withthe two heating furnaces in which the iron isbrought to the proper condition for workingit. The heading, upsetting and forging ma-chine was built by the Ajax ManufacturingCompany, of Cleveland, and will be usedlargely in the production of forgings fortrucks. This machine is capable of pro-ducing forgings of great variety in eithersquare or round stock 5 ins. and under, andwill operate on flat stock up to 15 ins. width, making bolts, upsets and special shapes. It has a lock and automaticstop between the pitman and header slide, arranged togive one or more blows as desired, and stop with dieswide apart. This is effected without the use of aclutch or similar device, so that the machine does its work. FORGER FOR LARGE WORK without shock and is practically noiseless. The gripperslide is connected to and driven by the header slide, andeach is provided with heavy liners to prevent wear on thebed casting and to provide means for realignment of the slides incase of wear. The crank shaft and the pinion shaft are of steel, and run in solid sleeve-boxes let into the bed casting, which isbored out to receive them. This construction is claimed to bepossible only by the use of a single crank shaft. The machineis powerfully geared, the teeth being cut from the solid. Thegear, pinion and fly-wheel are each firmly keyed to their re-spective shafts. The machine requires 15 ft. x 9 ft. floor space;the diameter of the belt wheel is 56 ins., and the speed of the July 4, 1903.] STREET RAILWAY JOURNAL. 37 belt wheel is 175 r. p. m., the width of the belt is 8 ins., theratio of gearing is 5 to 1, and the total weight of the machine85, 000 lbs.
