Referring now to the drawing in which the various parts are indicated bynumeralsz' The" machine comprises a supporting frame which may, for convenience in manufacture or otherwise, include lower and upper portions; The
lower portion comprises a frame having front legs 12 and I4 and rear legs [6 and I8 disposedin a rectangular pattern; The front and rear legs I! and [6 at one end are joined by a transverse base member 20 and a' transverse cap member or cap22, and the legs l4 and 18 at the'opp'ositeend' by transverse base and cap members 24 and 23'; Longitudinal base members 28"join' the postsand transverse base members 20', 24.
The upper portion of the frame essentially comprises transverse end members'ore'nds' 30' and 32"which are respectivelysea'ted o'n and' secured to the caps 2 2" and 26 and are interconnected a'zigz'ag' flanged member'or rib 34' which includes a transverse portion 34A, the ends and rib' being topped bya" work supporting table 35'.
Mounted by the upper portion of theframeare oppositely disposed edger heads mounted on' upright axes which are laterally and vertically shiftabl'e; and angularly tiltable in therespective transverse planes oftheir axes; Theconstrue--" tions include longitudinally offset brackets" 38 and lllwhich are secured to and extend horizon tally away from the rear andfront sides' respec tively of the rib member 34 and respectively in clude dovetail races 38A, 40A, mounting comple mentary slides 42 and 44*which are adjustabl y shifted forwardly and rearwardly by" screw s 45'" Mounted on the slides 42 and 44 are brackets" 50, 52 which respectively include disc" and-48.
portions seated against the slides, and annular portions 50A, 52A, slotted along one side and provided with ear portions 50B, 52B similarly spaced, and with clamping belts 50C, 52C. The disc portion of each barrel is turnably centered by a pin 53 (Fig. 5) and has arcuate slots 54 through which cap screws 54A extend into the slide 44 (Fig. 9). Ihe screws 54A are loosened to allow disc shift and permit the axis of the barrel to be angularly inclined from the vertical in a plane transverse to the machine and thereafter are reclamped. Angular adjustment may be accomplished by a screw 54B which is threaded through a swiveling nut 54C carried by a bracket 54D attached to the slide 44. The screw 54B is rotatably secured in a socket 54E pivotally attached to the barrel 52A.
Clamped in the annular bracket portions 50A, 52A are substantially identical cylindrical barrels 55, which extend tliereabove and therebelow. Each of these barrels (Fig. 5) has secured thereto a lug 55A which is internally threaded to receive an adjusting screw 56 through which the barrel is raised and lowered. An abutment 58 is anchored between the ear portions 52B and secured by a screw 60, the abutment journaling the screw 55 against longitudinal movement.
Shafts 62 are respectively journalled in each of the barrels 55 by bearings 64 which have their outer races seated against opposite outwardly faced annular internal shoulders in the barrel. The inner races of the bearings are spaced apart by a sleeve 66, and are confined between a shoulder 82A adjacent the upper end of the shaft and a nut 62B adjacent its lower end. Above the shoulder 62A the shaft carries an edger head 61. and below the nut 6213 a driving pulley 68 preferably of grooved type.
Clamped around the barrel above and below the bracket 52 are encircling brackets 10 having hub portions 10A from which arms 12 project laterally. The arms 12 are rigidly secured to and support the base 14 of an electric motor 16 which mounts and drives a pulley 18 and through a belt sildrives the pulley 68, shaft 62 and edger head 61. i
The above description defines a construction in which the edger head and driving motor as a unit, are adjustable without relative displacement the one to the other, toward or away from the work, and vertically and at an angle inclined to the vertical. The other barrel 55 mounts a similar assembly including an edger head 82 and motor 84. and establishes a similar unit.
Mounted on the end of the frame is a vertically disposed dovetail slideway 90 in which is mounted a complementary slide portion of a bracket 92. The bracket is raised and lowered by a screw 96. Mounted on the upper end of the bracket is a transversely disposed split housing 98 in which is mounted a barrel I00. The barrel is laterally shiftable by a screw I02 and clamped, except during shift, by screws I04. Journalled in the barrel is a horizontally disposed shaft I06 which extends into underlying relation with the table 36 and carries asurfacing head I01, the housing, barrel, and shaft construction preferably being substantially similar to that shown in Fig. 5 except that the barrel does not mount the related motor. The shaft I06 is driven by a motor I08 through a belt I09 and suitable pulleys. The motor I00 is mounted on a plate IIIl which is hingedly supported at one side by a rod III and at the opposite side by standing studs H2 and adjustable nuts II2A. The studs II2 are secured to and extend upward from the base members 28 of the machine frame. The motor is raised or lowered by adjustment of the nuts, to compensate for similar raising and lowering of the shaft I06 and cutter head I01 carried thereby. If desired a steady member I I4 may be secured to the hous ing, and therebeyond be offset to pass the head I01 and extended radially inward to journal the outer end of the shaft I06.
Overlying the table 36, is a complementary surfacing head II-B which is mounted on a shaft I I8 and driven through suitable pulleys and belts I I9 by a motor I20 mounted on a plate I IIIA which is adjustable with relation to the base 28 in similar manner to the plate III The shaft H8 is journalled in a housing assembly I2I and includes a vertically disposed slideway I22 secured to the transverse portion 34A of the zigzag rib 34 and a cooperating slide carried bracket I23 which is raised and lowered by a screw I24 and is substantially the same as the above described assembly carried by the housing 98. The assembly may also include an outboard bearing I26 for the shaft.
The lumber is preferably fed to the cutter heads by two pairs of corrugated rolls I28, I30 each pair comprising an upper and a lower roll. The rolls are driven at concurrent speeds, preferably by a motor I32 through a gear reduction unit I33 which through a chain I34 drives a countershaft I35. The countershaft; through a chain I36 drives the two lower rolls and through a chain I31 drives the two upper rolls. An idler sprocket I38 bears against the chain I31 and is adjusted by a screw I39, through an interposed spring I40. The two lower rolls are mounted on shafts I4I which are journalled in a cradle I42, this cradle being vertically slidable between an upright member I44 forming a part of the end frame 32 and a second member I46 secured to the end frame, and being guided by such members. A screw I48 provides means for raising and lowering the cradle and rolls to adjust the roll level with respect to the table surface.
The upper rolls are mounted on shafts I50 which are journalled in housings I52. The housings are carried by arms I54 which jointly pivot on a stud I56 which projects horizontally from a vertically disposed slide I69. The slide is sup- 3 ported and guided for vertical movement, by a complementary slideway portion of a bracket I58. The bracket has a base portion or base I58A, seated on the table 36 and secured thereto by cap screws I59, I59A, the latter of which (Fig. 12) passes through a slot I58B in the base, and when loosened allows a minor shift of the base about the cap screw I59 as a pivot, and permits a micrometric shift in alinement of the rolls I28 carried by the shafts I50. Shift of the base I58A is preferably accomplished by a screw IBI turnably mounted in an abutment IGIA secured to the table 36, the screw being threaded into one side of the base I58A. The slide I60 is linked to the bearing housings I52 through bolts I62. Interposed between the carrier and the housings are compression springs I64, the tension of which may be adjusted by nuts I66. Spacing of the upper rolls from the lower rolls, is adjusted by a screw I68 which raises or lowers the slide I60.
Mounted on the end frame 30 remote from the feed rolls and below the surfacing head I01 is "a bracket I 10, having arms I10A which project beyond the head I01 and carry rigidly secured up- .wardly extending braces I12 and in adjacency thereto are-apertured to receive a bolt I14. The .1 bolt I14 removably supports a vertical plate I16 which is additionally" secured in such upright position by screws I18 which are tapped-into the braces I12. Secured to the plate I75 are spaced guideways I80 which slidably engage the opposite edges of the vertical leg I82 of an angle'bracket.
The lower end of the leg I82 has an extending flange I82A through which is threaded an adjusting screw I84. The screw I84 is turnably journalled in an abutment 586 rigidlysecured to the plate I16.
Extending from the upper end of the angle leg I82 is the horizontal leg I88 of the angle member. The leg I80 mounts an auxiliary table I90 which has the general level of the table 35 but which maybe raised above or lowered below that table by the screw I64. The underside of the table I99 and upperside of the horizontal leg are provided with complementary keyways I90A and I88A respectively parallel to the longitudinal axis of the table 36 in which is disposed a key I92, which allow the table I90 to be shifted toward or away from the surfacing head #01. The leg 588 is also provided with slots IBBB laterally disposed in parallelism with the keyways through which clamping screws I94 engage the overlying table I90. Mounted on the table I 90 are longitudinally disposed guides I96 of angle cross section which are adjustably clamped to the table by bolts I98 which pass through laterally disposed slots I580 in the table I90. The table is adjusted by leveling screws I99.
The table 36, also, is preferably provided with adjustable extensions 200, whch are countersunk to table level and are longitudinally slotted to receive clamping screws 202.
In use the lower feed rolls I28, are adjusted by the screw I48 relatively to the level of the table 36, and the upper rolls I30 are spaced from the rolls I28, to conform to the thickness of lumber to be surfaced, by the screw I 68.
The lower surfacing head I01 is adjusted through the screw 96 to proper level with regard to the table and the upper surfacing head I I6 adjusted through the screw I24 as required to cut the desired thickness of finished lumber. To conform to these adjustments the plates H and II 0A are raised or lowered by the screws II 2 to maintain proper spacing of the motors I08 and I20 from their related surfacin heads I01 and H6.
The edger heads, 51 and 82 are vertically adjusted by shift of the barrels 55, as through the screw 56 (Fig. and if desired inclined to bevel the lumber edges, by loosening the screws 54A (Fig. 6) and turnably shifting the plate 52, and the related barrel 55, with reference to the slide 44.
The width of the lumber edged, is determined by shift of the slides 42 and 44 relatively to the brackets 38 and 40, by the screws 46 and 48, and shift with these slides of the barrels 56 carried thereby and the edger heads journalled by the barrels.
This shift of the barrels effects a concurrent shift of the motors, l6 and 84 which are rigidly supported by the barrels and maintains the driving relations of the motors to the edger head shafts.
As the lumber is fed through by the rolls I28, I30 toward the edgers, its longitudinal alinement may be adjusted by shifting the upper rolls I30 through the adjusting screw I6 I It will be understood that while the cutter heads are shown with straight knives attached to established cylindrical heads, the knives may i" have such other patterns either well known or otherwise as maybe desired: and that their configuration forms no part of the present invention.
It will be further understood that much of the detail shown is illustrative only and' that I do not wish, or intend to limit myself to such detail except where in any claim it may be set out.
