Having the circular cutters on the revolving shafts on the same inclined plane, the first and second cutters on each shaft wilt not come in contact with the flue, but will afford an easy entrance, acting like a mill, preventing the machine from choking; there id no. sticking, as the cutters are all revolving.

AND PEDRICK AYER engineers VA A ma kers, of Hamilton and 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.
