. Pattern-making machinery manufactured by Richards, London & Kelley, Atlantic works, Philadelphia . d machinery manufacture, proving awant for regular lathes of sufficient capacity for large patterns. The Lathe illustrated on the opposite page, although of sufficient size to turnthe largest pieces, is by careful arrangement made comparatively light in weightyand occupies but a small space on the floor. Pattern shops are generally on upper floors that are not strong enough tosupport heavy machines, besides the cutting operations in pattern-work are alllight, a large face Lathe is required not because of the nature of the work somuch as its size, that is, the cutting requires but little more power on a largepiece than it does on a small one, but the work being done farther from thespindle and the rest supports, and the lathe heavy to start, provisions haveto be made to suit these conditions. The Lathe shown in the engraving, although it swings 6 feet inside the restis but little heavier, and costs but little more than the shear lathe already,described. ATLANTIC WORKS, PHILADELPHIA. 19. Scale, LARGE FACE LATHE, FOR PATTERN TURNING. This Lathe swings 6 feet inside the rests, and clear of the floor, or to any largersize by providing a pit to clear the work. The spindle is ^ inches in diameter, the bearings of brass. Has four speeds,ranging from 250 to 1500 revolutions a minute, or as may be determined by thedriving pulley on the main shaft. The rests are supported on a bracket attached to the main frame, that isarranged to be swung out of the way for mounting large pieces. The main frame being cast in one piece, and the whole machine self-contained,no special foundation is required. The countershaft is placed in the main frameas shown in the engraving, or is furnished with hangers to go overheadwhen so ordered. Each Lathe is furnished with three face plates, two steel rests, the cone belt^and wrenches. For prices, see accompanying list. 20 MACHINERY FOR PATTERN-MAKING.
