Large Double-Cylinder Roll-Feed Surface-Planing Machine.

With Self-Acting Pressure-Bars ancl Forged-Steel Cylinders.

Planes on Both Sides to 30" wide and 6" thick.

The engraving upon the opposite page is a correct illustration of our Large-Size 30" Double-Cylinder Roll-Feed Surface-Planer. The closest scrutiny of everyfeature and detail is invited, believing it will be found unrivaled in facility andease of adjustment, durability, capacity, and quality of work.

It is very heavy, the framing of the machine being made with heavy platesides, with internal ribs. The joints are planed, holes reamed, bolts turned, andevery part built in the most thorough and careful manner, and is one of the mostreliable and powerful roll-feed surfacing machines made. It will surface on oneor both sides from to 30" in width, and to 6" in thickness.

The upper and lower cylinders are made from solid steel forgings, formedwith steel lips upon their faces, have large journals, lead-ground and finished inthe very hest possible manner. The upper cylinder is stationary, the bed risingfind falling to suit the thickness of the material. The lower cylinder runs inconnecting bearings, and has a vertical adjustment with the platen (or bed). Itis easy of access, as the Tipper housing, carrying the pressure-bar over it, can beswung entirely out of tbe way. Both cutter-lieads are belted on each side, althoughthe engraving shows the lower belted upon one side only.

Self-acting pressure-bars are placed upon each side of the upper cylinder.The one on tlie leading-in side works automatically with the feeding-in roll,Which allows the edge of the bar to work close to the cutters. Pressure-bars arealso placed close to the cut upon each side of the under cylinder.

The feed-rolls, four in number, are of large diameter and heavily geared,Wfith a part of the train upon each side, forming a powerful feed, and securinga very uniform draught. They are supplied with a superior weighting attach-hient, and readily adapt themselves to varying thicknesses of material. A coverextends from the cylinder to the front pressure-bar, entirely excluding dust andshavings from tlie feeding-out rolls.

The feed is started and stopped by means of a belt-tightener, operating uponth-e slack side of the belt, actuated by a hand-lever. The lied, or platen, is gibbedto the sides of the machine, and is raised or lowered by means of a hand-wheelTt the end of the machine.

The tight and loose pulleys are 12" x 8", and should make 900 revolutions
