Very little power is required to run the machine; it is operated by a labourer, who enters the flues in the machine (one at a time), they being revolved and fed through like a screw, and drop off on the opposite end without assistance. It will clean %es from 1 | to 3£ inches diameter, at ffjibji jr to 6 feet per minute, removing aJLscale without injury to the. flue, and ft ^ak^s tj |p ,yery little room, being almost noiseless, making but little dust.

PEDRICK & AYER , engineers J VA <M3 A ma kers, of Hamilton and • ' ^itowood-streets, Philadelphia, are the makers of the 30 -inch open-side planer and shaper shown in the accompanying illustration. In several constructional details, this machine differs somewhat from others in the market. The sliding head and cutting tool are supported by an overhanging or extended arm, moving parallel with the slotted side of the bed, and the work to be planed remains stationary, being fastened to the plates or tables as may be required. The open side permits the planing of large and difficult pieces ; and, as they remain at rest whilst being planed, are easier to set and fasten than they would be upon a moving table or platen. The saddle is moved by means of a screw and pulleys, with shifting belts, has quick return, and is easily controlled by the operator.
