Doane’s Patent Duplex Planing and Matching Machine.

Works two separate Flooring Boards at one Operation.

Capacity, 40,000' to 60,000' per day.

As the profit of the planing mill is principally made up hy the differencebetween the value of the rough lumber before it is dressed and the value ofthe same after it has come from the mill, that machine which will perform thegreatest amount of perfect work in the shortest time, with a proportionateeconomy of labor and power, will commend itself to every one interested inthis class of machinery. The Duplex Planing Machine shown herewith has acapacity of from 40,000' to 60,000' per day. Its distinguishing feature is itsability to work simultaneously two flooring or ceiling boards up to 8" inwidth, finishing them on both sides and edges, as well as beading the top atone operation.

It is simple in all its arrangements, and can be worked by any intelligentoperator with as much ease as an ordinary flooring machine, while the capacityis double. It is in no sense complex, but remarkably simple. The machine ismassive and heavy, with broad sole-plate, insuring a large floor base. It has twoshort (or duplex) upper cutting cylinders and one lower cylinder, and will planeboth sides up to 6" in thickness, and match up to 8" wide two pieces of floor-ing of equal or unequal thickness simultaneously. There are six feeding rollsof large diameter, driven by a train of powerful gearing of the most substantialcharacter. The upper rolls are made in sections so two boards of different thick-nesses may be fed and planed at the same time.

It has automatic self-acting pressure-bars before and after the cut of theupper cylinders. The under cylinder is provided with duplex pressure-bars,each vertically adjustable independent of the other or simultaneously together.The cylinders are made of best forged steel, with chip-breaking lips for cross-grained lumber. The journals are extra large, lead-ground, and carry pulleys forwide belts with the bearings especially long, with deep lining of the choicestmetal made. The upper cylinder frames and bearings are planed to fit uprightstands, which are cast to a solid bed extending across the machine, securelytying them in the most rigid manner.

Both upper cylinders raise and lower simultaneously or independently ofeach other, thus allowing the machine to be used as a duplex machine, workingtwo pieces of lumber at one time, or as a simple flooring machine, making onlyone. The matching works are duplex, and work the edges of both boards at oneoperation. They are adjustable to suit the width of lumber from the face sideof the machine. The pressure-bars over the lower cylinder can be quickly movedback when access to the cutters is desired. The lumber-platen is provided withduplex board-guide; also the patent automatic edge-feed for guiding the lumberin a straight line to the first receiving feeding rolls, even if warped and crooked.

In the ordinary planer and matcher the cutting cylinders revolve at highspeed, with the feed of the machine increased to its utmost limit, in some casesfrom to at each stroke of the knives, necessarily leaving the marks of eachcut iipon the lumber. With this machine the result is quite opposite. The feedbeing slower, the operator is enabled to feed two boards side by side with moreease than one in the rapid-feed machines, and, as the cutting cylinders have moretime to act upon the lumber, it comes from the machine with the surface in amuch higher finished condition. Weight 14,000 pounds.

The tight and loose pulleys are 16"xl0", and should make 950 revolutions.
