Patented Oct. 23 1945 l UNITED STATES PATENT OFFICE HIGH SPEED PLAN ER Wolfgang Rossmanith, Solothurn, Switzerland;

vested in the Alien Property Custodian Application June 19, 1942, Serial No. 447,690 In Germany June 21, 1941 1 Claim. (Cl. 90-38) The present invention relates to high-speed the work-table is only utilized for moving the planers. Planing machines are known where the work-piece. A machine of such an arrangement i001 during its whole stroke along its Whole length works exactly and cleanly. It is especially suited is guided in a guide member rigidly fast to the for heavy work and bulky work-pieces. It may Standard f the machine. Standard and guide 6 be constructed as a one or a two pillar machine. Y

member may also be arranged to form a closed The annexed drawing shows by way of example frame by means of a support serving also as a a planing machine according to the present inguide for the work-table which is adjustable in venton diagrammatically in side View.

The long continuous guiding means of In the gure, the pillars b and b1 are located the tool in combination Vwith the rigid frame peron the two sides of the table a which may execute mits the use of hard metal tools and thereby a its feeding movements on the base a1 at right high planing speed. The double mobility of the angles to the plane of the drawing.

But the tool carrier is made rier, which is adjustable vertically, a simple aradjustable in height along lateral pillars, 'which rangement is attained whereby advantageous pillars also support its mechanism for securing performance is secured without complicated drivhorizontal movements. The tool travels in an uning mechanisms.
