1 Claim.
This invention relates to improvements in veneer; andz-has for its objectto provide a strip of veneer in which: the. outeredges aresubstantially straight and. theresis formed on the strip a plurality 0f, symmetrical wood'grains.
It is particularly the object of this invention to provide. stripsof wood veneer in which there is a plurality of cross sections through the same wood grain, and also in which these sections are symmetrically arranged.
An illustration of the form of strip and wood graining is shown in the drawings. In Figure 1 there is shown a strip of wood veneer cut from the end of a log or piece of work at one single operation, but by a plurality of rotations of the work.
Referring to the drawings: Figure 1 is a top plan view of wood veneer formed according to the present invention.
Figure 2 is a vertical section through part of the machine used for making the wood veneer.
Figure 3 is a top plan view of the machine shown in Figure 2, with parts thereof removed for showing the blade and associated structure.
In Figure 1 the piece of wood veneer is indicated by the numeral 1 and is substantially of the size and shape of the piece from which it is out, which may be a block or alog so arranged that there are, as shown, four symmetrically arranged groups of wood grainings. The sides or edges of the strip are indicated by the numeral 2 and show that the strip is substantially square when cut from the log. symmetrically arranged on the strip are the groups of wood grainings 3.
necessary, and this is indicated by the numeral 4. As the log or work piece rotates a knife cuts the strip from the log or piece of work. The cutting begins and ends at the point 4, as far as the single piece is concerned. This piece, as shown in the drawings, is formed by four rotations of the log, with the end so arranged with relation to the cutting blade that a cone-shaped strip is formed, which when spread out, produces a strip of the shape shown in the drawings.
The machine used for making the wood veneer shown inFigure'. l is shown in Figures-2 and-3.
The numeral 5. is used to designate standards, which support aplatfcrm 6; located betweenthe standards. In practice there are four of: these standards, used for. supportingthe l platform 6; Inthes central part' of theplatform, suitably attact-reds thereto, is abearing Twhicli has therein a vertical shaft 8 about which is a collar 9, resting upon the bearing '7.
Upon the collar 9 is a gear 10 mounted on the upper end of the shaft 8. Above the gear 10 and about the reduced upper end of the shaft 8 is a friction plate 11, which has thereon a disclike carrier 12 which receives the veneer cut from the log during the cutting operation. The gear 10 is engaged by an operating pinion 13 located on a vertical shaft 14, suitably supported in bearings in the platform 6, and the frame located above the platform.
On the shaft 14 above the frame 15 is a pinion 16 which meshes with teeth on the periphery of a gear 17. This gear has a large central opening therein, and has beneath it and around the open- Eng a disc 18. To this disc 18 and the gear 1'7 is attached a cone-shaped member 19, which has at its upper end a flange 20 suitably afiixed to the disc 18. This flange, in cooperation with the disc 18, forms a groove 21 around the periphery of the disc to receive rollers 22, suitably mounted upon the frame 15, around the disc 18, for supporting the cone, the disc and the gear 17 for rotation. The rollers 22 support the disc 18 by means of a peripheral projection 23.
The cone-shaped member 19 has in one side a slot 24, and has extending tangentially from the slot, on one side thereof, a flange 25, which has on its outer end a lug 26. This flange supports a bar 27, which has one edge adjacent the slot and is engaged at its other edge by a screw 30, which extends through the lug 26. This bar has therein one or more slots 28 for receiving a screw 29 to hold the bar in adjusted position.
Between the bar 27 and the flange is a wedge 31, which has therein a slot 32 for receiving the screw 29. The back or flat edge of the wedge is engaged by means of a screw 33, which extends also through the lug 26. This wedge is used to adjust the angular position of the bar. On the other side of the slot 24 from the flange 25 is a flange 34, which has on its outer end a lug 35. This flange also has in its face a depression or recess 36 adapted to receive a part of a. knife holder 37. This lmife holder has on its edge adjacent the slot 24 an arcuate inner face 38, corresponding in curvature to the curvature of the cone member 19.
For the purpose of adjusting the knife holder to and from the slot 24 there is provided a screw 39, which passes through the lug 35 and engages the outer edge of the knife holder. There is also provided for holding the knife holder with relation to the flange 34 a screw 39a. The screw 40 is used for holding the knife holder, which extends through a slot 41 in the knife holder into the flange. The knife is indicated by the numeral 42 and is held in spaced relationship with the knifeholder by means of a wedge 43. The wedge and the knife have one or more slots 44 therein, through which the screw 40 passes, and through which also the screw 45 passes for holding'the knife and the wedge closely against the knife holder.
The outer edge of the knife is engaged by means of an adjusting screw 46, which is threaded through a lug 47 on the knife holder. The outer edge of the wedge 43 is engaged by means of a screw 48, also threaded in the lug 47.
The log worked on and from which the veneer is cut is indicated by the numeral 49. As the cone member 19 rotates a spiral piece of veneer 50 is cut from the end of the log. It will beobserved from an examination of Figure 2 that the center line of the cone member 19 is out of alignment with the center line of the log so that the end of the log is not evenly cut, and when the veneer is cut from the log a piece of veneer, of a nature such as that shown in Figure 1, is produced.
The log 49 is held stationary with regard to the cone-shaped member 19, which is rotated by some suitable power connected to the shaft 14.
