Description
PORTABLE PLANK EDGER
of the Invention The present invention s to the field of lumber processing and is particularly concerned with a portable plank BACKGROUND OF THE INVENTION:
The processing of lumber and particularly the manufacture of studs from log blocks involves manipulation of the logs prior to their insertion through bandsaws which cut the log into cants typically having two or four inch thicknesses. The wane edge on a plank or cant is the rounded or non squared edge resulting when such plank or cant is sawn lengthwise from a round log.
Such wane must be removed, within certain tolerance restrictions before the plank or cant is processed into dimensioned lumber.
.../2 The next step in the lumber processing in order to obtain studs from log locks thus includes moving the cants to ganged edgers where they are further cut into studs thereby typically yielding either 2 x 2, 2 x 4 or 4 x 3" studs.
These operations are typically performed in so called sawmills. Sawmills range in size from extremely large mills to a portable type mill that can be trucked to the site and set up as a one man or two men operation. The large mill is of course not portable to the extend that it can be set up in a short time and in a small space. The small portable mills, while being of smaller size and operable by one or two persons have the disadvantage that they are limited in their function because they clamp to the log and thus can only work on the larger type logs.
One of the main disadvantages of the prior art portable saw mills relates to their lack of versatility since for the most part they are only adapted to handle logb(ocks so as to transform them into planks having wane edges. Hence, there exists a need for a portable edger specifically configured so as to be readily adaptable to work with a conventional portable sawmill.
The advantages of the present invention include the fact that a edger in accordance with the present invention is specifically designed so as to be readily attachable to a conventional portable sawmill preferably using the power source of the sawmill as its own power source.
Furthermore, the portable mature of the proposed edger allows the latter to be easily and ergonomically mounted to a conventional sawmill without requiring special tooling or manual dexterity.
.../3 Furthermore, the edger may also easily be removed from the conventional sawmill when not in use. The edger further has a collapsible construction so as to minimize storage space when not in use.
Also, the proposed edger has built-in ergonomic adjustment means that allow for adjustment of the thickness of the wane edge being removed by simple ergonomic manipulation of its components.
Also, the proposed edger is constructed so as to conform to conventional forms of manufacturing so as to provide a edger which will be economically feasible, long lasting and relatively trouble free in operation.

DETAILED DESCRIPTION OF THE DRAWINGS:
Referring to Figure l, there is shown a portable rectifier 10 in accordance with an embodiment of the present invention mounted adjacent a conventional portable sawmill 12 schematically illustrated by its frame 14 and only some of its components.
The frame 14 of the portable sawmill 12 includes elongated frame rods assembled together as is well known in the art to support sawmill components such as the drive means taking the form a motor 16.
The portable sawmill frame 14 is preferably mounted on corresponding sawmill wheels 38 as is well known in the art. The motor 16 has a driving pulley 18 mechanically coupled thereto. The driving pulley 18 has a driving shaft 20 mounted thereon for providing power to the portable edger 10 as will be hereinafter disclosed.
../5 - S -The portable edger 10 has an edger frame 22 mounted on corresponding edger frame wheels 24. The portable edger frame 22 preferably includes generally elongated edger frame rods 26 releasably attached together by conventional nut and bolt type components 28 so as to provide a collapsible nature to the edger frame 22.
The edger 10 has an edger conveyor 30 for supporting planks 32 being processed. The edger 10 is configured so as to be readily attached to the frame of the conventional portable sawmill 12.
In a preferred embodiment of the invention, the conveyor 30 of the edger extends in a generally perpendicular relationship relative to the longitudinal orientation and thus of the conveyor (not shown) of the portable sawmill 12.
The conveyor 30 is provided with conventional rollers 34 rotatably mounted transversally thereacross as is well known in the art.
Referring now more specifically to Figures 3 and 4, there is shown in greater details a preferred embodiment of the construction of the edger frame 22.
The edger frame 22 preferably includes four base rods 36 maintained in generally vertical and spaced alignment relative to each other by a corresponding set of four base spacing rods 38 forming a generally rectangular configuration.
A distal end of the base rods 36 is preferably provided with a base plate 40 for abuttingly resting against the ground surface. The proximal segment of the base rods 36 is provided with a connecting tongue 42 having a connecting aperture 44 extending therethrough.
.../6 A cover plate 46 having a flange 48 extending therefrom is adapted to be releasably mounted to the base rods 36 with cover rods 50 extending substantially perpendicularly therefrom. The cover rods 50 are hollowed out at least at their distal end and provided with a corresponding cover connecting aperture 52.
A cover connecting aperture 52 is adapted to be put substantially in register with the connecting aperture 44 extending from the base rods 36 so as to allow insertion of a conventional anchoring component such as a nut 54 and bolt 56 assembly as is well known in the art. The flange 48 preferably has a generally "C"-shaped cross-sectional configuration so as to allow through passage of components along its longitudinal direction.
The spacing rods 38 may optionally define a platform for supporting an auxiliary drive means preferably taking the form of an auxiliary motor 58 having an auxiliary pulley 60 mechanically coupled thereto for driving and auxiliary driving belt 62.
Referring now more specifically to Figures S and 6, there is shown some of the components mounted within the edger frame 22. The edger frame 22 rotatably supports a set of supporting frame rollers 64 extending transversally thereacross and preferably mounted on corresponding ball-bearing type components 66.
A driving shaft 68 is rotatably mounted to the edger frame 22 through corresponding shaft bearings 70. The driving shaft 68 is mechanically coupled to the main driving belt 20 and optionally to the auxiliary driving belt 62 respectively mechanically coupled to the sawmill motor 16 and the auxiliary motor 58.
.../7 A fixed circular sawblade 72 is mounted on the driving shaft 68 adjacent a longitudinal end thereof. A mobile circular cutting disk 74 is also mounted on the driving shaft 68.
The mobile circular sawing disk 74 is mounted on a disk frame 76. The disk frame 76 is, in turn, slidebly mounted on the driving shaft 68 with a releasable locking means allowing for relative adjustment of the spacing between the sawing blades 72 and 74 as indicated by arrows 78.
A swingable lever-type component 80 is adapted to be used in a pivoting action as indicated by arrows 82 to provide spacing adjustment between the blades 72, 74.
A driving roller 84 is rotatably mounted on a driving roller lever 86. The driving roller lever 86 is, in turn, pivotly mounted on a pivotable lever sleeve 88.
A lever driving shaft 90 extends through the lever sleeve 88. The lever driving shaft 90 is mechanically coupled to a lever driving wheel 92. The lever driving wheel 92 is mechanically coupled to a set of gear and belt arrangements 94 to the driving shaft 68. An inverting gear 96 is mounted on the roller shaft 90.
A chain 98 mechanically coupled to the inverting gear 96 to a driven roller gear 100. The driving roller 84 is provided with a surface texture having a relatively high friction coefficient and is thus adapted to fractionally pull on the outer surface of the plank 32 for driving the latter through the edger while the cutting disks 72, 74 trim away the irregular or wane edges of the plank 32.
.../8 _ 8 _ Optionally, instead of using a mobile cutting disk 74 a set of auxiliary cutting disks in predetermined spaced relationship relative to the main cutting disk 72 may be used.
Also, preferably, the rods making up the edger frame are provided with apertures extending therethrough so as to reduce the overall the weight of the frame and increase its maneuverability.
