Application June 15, 1956, Serial No. 591,643 2 Claims. (Cl. 145-4) The present invention relates to a portable power plane.
An object of the present invention is to provide a portable power plane which lends itself to rapid and eflicient planing of woodwork pieces, one which leaves no planing marks on the workpiece, and one which may be easily guided on the workpiece and having no tendency to creep laterally of the workpiece.
Another object of the present invention is to provide a portable power plane which is light in weight and easily portable, one which is sturdy in construction and fabricated of few parts, easily manufactured by casting and machining, and one which is economically feasible.
These and other objects and advantages of the present invention will be fully apparent from the following description when taken in connection with the annexed drawings, in which:
Figure 1 is a perspective view of the portable power plane of the present invention;
Figure 2 is a sectional view taken on line 22 of Figure 1;
Figure 3 is a sectional view taken on line 33 of Figure 2;
Figure 4 is an elevational side View, partly in section, with the housing side pipes removed; and
Figure 5 is an exploded view of the power plane of the present invention.
Referring in greater detail to the drawing'in which like numerals indicated like parts throughout the several views, the portable power plane of the present invention comprises a base having upstanding flanges 11 and 12 at its ends and a pair of slots 13 and 14 arranged in parallel spaced relation transversely of the base 10 and inwardly of the flanges 11 and 12, respectively.
A transversely disposed tunnel member 15 bridges the slot 13 and is connected in communication thereto, and another tunnel member 16 is similarly positioned with respect to the slot 14.
A planar assembly, indicated generally by the reference numeral 17, and consisting of an upstanding housing 18 having an open bottom and spaced sides 19 and 21 is positioned so that the side 19 bears against the flange 11 and the side 21 bears against the flange 12.
The housing 18 is closed on its one end by an upper plate 22 and a lower plate 23, and on its other end by an upper plate 24 and a lower plate 25. Bearing assemblies 26 are supported centrally of the upper plates 22 and 24 and receive the ends of a shaft 27 which is the drive shaft of an electric motor 28. A sprocket wheel 29 is carried upon one end of the shaft 27 and forms a driving means for the chain 31 which is drivably engaged with other sprocket wheels 32 and 33 upon the shafts 34 and 35, respectively, of a pair of horizontally disposed rotatable cutters 36 and 37, respectively, which extend transversely across the bottom of the housing 18 within the tunnel members 15 and 16, respectively.
Means is provided carried by each of the flanges 11 and 12 and engaging with means formed on the housing sides 19 and 21 for adjusting the housing 18 relative to the base 10 to thereby regulate the depth of cut of the cutter blades 38 and 39. Specifically, the means carried by the flanges 11 and 12 embodies a'fastening element 41, specifically a bolt, supported in slots provided in each of the flanges 11 and 12 for limited up and down movement and detachably secured in means, specifically tapped holes, formed in the adjacent housing side 19 or 21.
The spiral blades 38 and 39 are formed so that their spiral shapes curve in opposite directions in order that no planing marks will be left upon the work piece as it is planed, the planingmarks left by the first blade being obliterated by the second blade.
Positioning pins 42 project upwardly from the base 10 into holes provided in the housing 18 and springs 43 bias the base 10 away from the housing 18 for easy and ready adjustment of the height of the housing relative to the base, which determines the depth of cut of the blades 38 and 39 into the work piece.
A pistol grip-type of handle 48 is provided on one end of the housing 18 and a ball-type of hand grip is provided on the other end of the housing 18 as at 49.
In use, the portable power planer of the present invention may be used to finish the surfaces of work pieces and the two cutters with their oppositely spiraled blades produce a smooth finish without planing marks and requiring little or no sanding in a finishing operation. The planer is easily portable and is readily adjusted for the depth of cut desired and according to the degree of hardness of the work piece to be finished.
What is claimed is:
l. A portable power plane comprising a base having an upstanding flange at each end thereof, there being a slot extending transversely thereof intermediate said flanges, a transversely disposed tunnel member bridging said slot and connected in communication therewith, a planer assembly including an upstanding housing having a bottom and spaced sides, and a horizontally disposed rotatable cutter extending transversely across the bottom of said housing within said tunnel member and spaced from the sides of said housing positioned so that the cutter has a peripheral portion projecting through said slot with said sides bearing against said flanges, a horizontally disposed drive shaft in said planer assembly and rotatably supported in the sides of said housing, a sprocket wheel carried by said drive shaft, another sprocket wheel carried by said cutter, a chain drivably engaged with said sprocket wheels, and means carried by each of said flanges and engaging with means formed in the housing sides for adjusting said housing relative to said base to thereby regulate the depth of cut of said cutter.
2. A portable power plane comprising a base having an upstanding flange at each end thereof, there being a pair of slots arranged in parallel spaced relation transversely of said base inwardly of said flanges, a transversely disposed tunnel member bridging each of said slots and connected in communication therewith, a planer assembly including an upstanding housing having a bottom and spaced sides, and a horizontally disposed rotatable cutter extending transversely across the bottom of said housing within each of said tunnel members and spaced from the sides of. said housing positioned so that 4 the cutter has a peripheral portion projecting through the adjacent one of said slots with said sides bearing against said flanges, a horizontally disposed drive shaft in said planer assembly androtatably supported in the sides of said housing, a sprocket wheel carried by said drive shaft, a sprocket wheel carried by each of said cutters, a chain drivably engaged with said sprocket wheels, and means carried by each of said flanges and engaging with means formed in the housing sides for adjusting said housing relative to said baseto thereby regulate the depth of cut of said cutter.
