Definitions

  • My invention relates to improvements in veneer and board cutting machines; and the objects of my said improvements are, first, to provide means for obtaining under all circumstances veneers and boards of uniform thickness throughout; second, to afford facilities for cutting wood of unequal constitution, and, third, to reduce the friction or resistance which the presser-bar meets with from the invention embodied therein.
  • Figure 1 is a vertical sectional view taken through a portion of the knife-carrying frame and illustrating my invention.
  • Fig. 2 is a similar view showing a slightly-modified form.
  • Fig. 3 is a top plan view of a portion of the Presser-bar, constructed as shown in Fig. 1, while Fig. 4 is a similar view with like relation to Fig. 2.
  • Fig. 5 is a top plan View of the presser-bar after another modified form.
  • Fig. 6 is a vertical sectional View of aportion of the knife-carrying frame with this form of Fig. 7 is an enlarged sectional View of the presser-bar last referred to.
  • presser-bar h of a considerable number of small parts h each of which to be attached separately to the slide it by means of bolts 4" and a layer of elastic material s-such as india-rubberis placed behind all parts h of the resser-bar, Fig. 1, so that each part may yield independently from the other under the pressure and according to the varying resistance of the wood at different points of the cutting-edge of the knife.
  • This construction of the presser-bar is particularly applicable in cutting wood of unequal constitution-ms, for instance, knotty or branchy wood.
  • each pin r As the end of each pin r extending beyond the bottom 7' is provided with threads upon which is screwed a suitable n ut W, the tension of each spring maybe conveniently regulated and also each part h of the presserbar easily adjusted in such a manner that the pressing-edges of the same, just behind the cutting-edge of the knife, will form a straight line throughout, Fig. 9.
  • This device is particularly applicable where it is desired to secure an absolutely-parallel yielding motion of each part of the presserbar in relation to the cutting-edge of the knife, as for this reason a certain space must be left between the parts W of the presser-bar and the bar .2 on top of each part h is fastened a plate rfloverlapping the said space, and so protect the same from being 00- cupied by chips or dirt of any kind.
  • thesingle parts h of the latter may beprovided atthat edge which bearsagainst the wood with smallanti-friction rollers h in such a manner that only a small part of their periphery will project beyond the presser-bar, Fig. 6.
  • These rollers have to be arranged, respectivel y, the knife adjusted in such a 'manner that a plane thought to belaid at right angles from the cutting-line or the cutting-edge of the knife will exactly meet the axes of the antifriction rollers, so that the said rollers will receive the pressure caused from the resistance of the wood to be cut, in order to discharge the knife entirely from lateral pressure of the wood.
  • These rollers may be divided themselvesin the single parts h of the presser-bar, or one flexible roller may be used simultaneously for two or more separate parts of the presser-bar without departing from the nature of my invention.
  • the combination as an improvement in wood-working machinery for cutting boards and veneers from a block of wood, the combination,with the knifeframe carrying a knife, of the presser-bar composed of a series of independent sections, the bolts or pistons secured to said sections, the rigid bars, to which said bolts are connected, and the elastic or spring pressure in said bar forcing outwardly on said bolts and sections, as set forth.
