The heavy forge planer, illustrated herewith, was exhibited atthe Atlantic City conventions by The Cincinnati Planer Company,Cincinnati, Ohio. It was driven by a 15 constant speedmotor which transmitted power to the speed box through a raw-hide pinion and a cast iron gear. The speed box furnished fourchanges of cutting speed, 20, 28, 35, and 45 ft. per minute, with aconstant return speed of 80 ft. per minute. The s

The speed box furnished fourchanges of cutting speed, 20, 28, 35, and 45 ft. per minute, with aconstant return speed of 80 ft. per minute. The speeds arechanged by the vertical shaft and handles, shown at the speed box is enclosed and all the gears run in oil. The bed is made of extra length, so lhat there is very littleoverhang of the table when planing at full stroke. The Vs arefitted with automatic roller oiling devices. The table is carefullydesigned for unusual strength and stiffness and is arranged witha dustproof feature which prevents the chips from falling into. to the fact that it is frequently necessary to look at the tool orrub it up with an oil stone, it has been heretofore a little trouble-some to pull them out on account of this spring; with this littlehandle it is only necessary to push the handle down and the toolblock may be pulled out its full limit. Provision is made so thatside heads may be attached to machines not equipped with themwhen purchased, at any future time. A patent elevating deviceis located at the center of the arch and provides a third bearingfor the elevating shaft, distributing the pull equally. This de-vice is driven by a belt connected to the pulley, mounted on thebrackets above the speed box, which is in turn driven from thespeed box shaft. Ordinarily the elevating device is driven directfrom the speed box shaft, but the construction of this particularmachine would not admit of doing this.
