EPECIFICATION forming part of Letters Patent No. 337,654, dated March 9, 1886.
Application filed November :24, 1885. Serial No. 183,845. (No model.)
To all whom it may concern:
Be it known that I, EMERSON BELDEN, a resident of Green Island, in the county of Albany and State of New York, have invented certain new and useful Improvements in Planing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
Similar letters refers to similar parts in the several figures therein.
My invention relates to improvements in planing-machines, and more particularly to machines for planing and dressing doors.
The objects of my invention are, first, to provide in a door-planer smaller and lighter cutting heads or cylinders in sections, whereby greater speed is attainable with less vibration and friction, and the laterally middle portion of the planed surface may be cut to a higher or lower level than that of the side portions, as hereinafter more fully described; second, to provide means for simultaneously'cutting off the wedges in the edge of an unfinished door and planing the edge of the door.
My invention consists, first, in providing an overlapping and overhung sectional cylinder, the cuttingsections being adjustable relatively to one another, as will be more fully described; second, in providing a vertical cutter-head adapted to cut up to a guide-line, suitable guides on one side of the line, and an adj ustable spring on the other side to hold the material against the guides.
Figure 1 of the drawings is a plan view of my improved planing-machine. Fig. 2 is a side elevation of same.
A'is the supportingframe provided with a superimposed cylinder-supporting cross beam, 13, feed-rollers R R, guides G on one side of the frame, and an adjustable retainingspring, S, attached to the side of the frame opposite the guides. One end of the door is laid flat upon. the frame between the spring and guide and pushed between the feed-rollers R R, which in the usual manner impel the door forward in the direction of the broken span the Widest door.
line :10 y, to and beneath the sections 0 G of thehorizontal cutter head or cylinder, and to one side of the vertical cutter'head D. The horizontal cylinder or cylinders dress oneface of the door and the vertical cylinder one edge, cutting off the projecting wedges and tenons and leaving the cdgeof the door planed smooth throughout its length, the spring S serving to keep the edge of the door to be planed firmly against the guides G, which are sufficiently thin to allow the uncut wedges projecting from the door to extend out over. the top of the guide, whereby the vertical cutter can be set in a position relatively to the guides, to cutoff all projections from the edge of the door and leave the same planed straight and smooth. At the same time the horizontal cylinders smooth one face of the door. After one face and edge are finished, the door is turned over and the other face and edge treated in the same manner. I
Heretofore saws have been employed to cut off the projecting wedges; but they left the edges of the door rough, and it was necessary .to afterward plane or dress them off by hand.
By employing the vertical cutter-head in connection with the guides and spring or an adjustable stop, S, I am able to out off the wedges and dress the edge of the door at the same time, leaving the edge finished.
Heretofore asingle horizontal cylinder has been employed for dressing one face of a door, which cylinder was necessarily of a length to The rapid rotation required of the cylinder made it necessary to construct the same of a comparativelylarge diameter to give it sufficient strength and reduce vibration. In large cylinders the knives do not come in contact with the surface to be 0 planed at so sharp an angle as in cylinders of a smaller diameter, and the surface is liable to chip up and be left rough, and it is well known that more work can be done with small than with large cylinders. I overcome these objections by constructing my cylinder in sectionstwo or morewhich overlap each other and are supported by boxes, which at the overlapping ends overhang the door, beingsecured to the cross beam which spanstheframe. The
cross-beam is provided with supports b and b, which sustain in an overhanging position the boxes c a. The other ends of the sections 0 C are supported by boxes secured to the frame or to the projeetinglugs d d'ot' the crossbeam, which are bolted to the frame in a manner to firmly secure the beam substantially asshown. It will be seen in Fig. 1 that the overhanging ends of the sections overlap each other and the broken line a: y, whereby they act upon the entire face of the door to give it a smooth and finished appearance.
By adjusting the ends of the cylinder knives to different levels relatively to one another the thickness of the door at the middle portion may be varied relatively to the thickness at the sides oredges. For example if theknives on the two sections are so adjusted that the overlapping ends, when rotated, describe a larger circle than the other ends, the door will be concaved or scooped out along the whole length of its middle portion, which makes it possible to out out imperfect ions in thesurtace of the door without materially diminishing its thickness at the edges when it comes in con tact with the vertical casings of a door-opeir ing. The relative levels of the section ends may also be varied by loosening, ortightening at one end of the eylirider-sections the bolts or screws which hold down the upper section of the boxes.
The eylinder-seetions are provided at their outer ends with pulleys g, adapted to receive operating beltst'romaeonnter-shal't. The vertieal h aid 1) is attached to sltal't i, provided with a driving-pulley. b.
By dividing the cutting-cylinder into sections I not only lessen the vibrations of the cylinder and liability of the journals to heat, but increase their speed and capacity for work.
By means of the adjustable arm 6 the position of the spring S can be accommodated to doors of different widths.
The arm is secured in position on the frame by means of a set'screw passing through slot m.
What I claim as new, and desire to seenreloy Letters Patient, is
1. In a machinetbr planing doors,aseetional cutting-cylinder composed of overlapping sections provided at their overlapping ends with bearings supported by a spanning; cross-beam, substantially as described, and for the purposes set forth.
2. Theeombinatiolnwith the frame ot'aplaning-maehine, of a spanningcrossbeain centrally provided with cylinder: bearing sup ports, and of two cutting-eylinders supported at their contiguous ends by said bearing-supports, the other ends of said cylinders being supported at opposite sides of said frame, substantially as described, and for the purposes set forth.
In a planing"-machine, the cross-beam B, 7
provided with the opposirely-projecting bearing-supports l) b, in combination with the cutting cylinders G- G and feed rolls R R, sub stantially as "described, and for the purposes set forth.
in testimony whereof I have hereuntoset my hand this 21st day of November, 1885.
