UNITED STATES PATENTS 2/1875 Hempel 83/762 6 Claims, 5 Drawing Figures CORNER CLAMP MITRE BOX The present invention relates to an improved mitre box saw guide.
In the past, there have been many mitre boxes for obraining guided desired angle cuts on an object to be sawn.
The most common mitre box is of course the wooden U-channel mitre box with its 90, 45 angle slots.
Longer lived mitre boxes have been made of metal and often have been improved by clamps and saw guides, adjustable saw guides and even saw rollers.
Adjustable guides have been provided in the past to minimize the deviation of the saw when making a mitred cut by having the saw fit snugly in the slot without much side-to-side movement.
According to the present invention, an improved mitre box having clamps is provided, adapted to several angle cuts and having an improved roller system enabling easier and more accurate cutting.
Although such novel feature or features believed to be characteristic of the invention are pointed out in the claims, the invention and the manner in which it may carried out, may be further understood by reference to the description following and the accompanying drawmgs.
FIG. 1 is a plan view of the present invention.
FIG. 2 is a left-side elevation view of FIG. 1.
FIG. 3 is a section of a pair of rollers in its closed position, taken along lines 33 on FIG. 1.
FIG. 4 is a section of the rollers taken along line 44 on FIG. 3.
FIG. 4a is a view of FIG. 4 in its open position.
Referring now to the figures in greater detail, where like reference numbers denote like parts in the various figures.
The mitre box 10, shown in FIGS. 1 and 2, has a metal base 11 including a first saw slot 12 and a second saw slot 13.
There is a first rear brace wall 14 as an end portion set apart from a second rear brace wall 15 as an end portion.
The first and second rear brace walls 14, 15 are separated by the slot 12 which passes diagonally between the brace walls 14, 15 at about a 45 angle.
The front part of the slot 12 passes between uprights 16, 17 as end portions adjacent each other. On the first and second brace walls 14, 15, straddling the slot 12 is a first pair of rollers 18, 19. Opposite the first pair of rollers 18, 19 on the uprights 16, 17 is a second pair of rollers 20, 21.
The second rear wall 15 is also split by the slot 13, which passes through the wall at about a 90 angle. The other end of the slot 13 has a pair of uprights 22, 23 through which the slot 13 passes.
The rear wall 15 has a pair of rollers 24, 25. The uprights 22, 23 also have a pair of rollers 26, 27. Each of the roller pairs 18, 19', 20, 21; 24, 25; 26, 27 are aligned with the roller 18 and roller on one side of the slot 12 and the rollers 24 and 26 on one side of the slot 13 and the rollers and 27 on the other side of the slot 13.
The mitre box 10 of the present invention also includes a pair of clamps 28, 29. The clamps 28, 29 are mounted on screws 30, 30' which may be rotated from the handles 31, 32 to slide the clamps 28, 29 back and forth along the guides 42, 43.
It is preferable to have the rollers 18, I9, 20, 21, 24, 25. 26, 27 mounted on sleeves 33, as shown in FIG. 3, which fit rotatably but snugly within the rollers 18, 19, 20, 21. 24, 25. 26, 27. The sleeves 33 are preferably of a length a bit greater than the rollers.
The sleeves are held to their respective walls 14, 15 on uprights 16, 17, 22, 23 by screws 34, 35, which have flanged heads 36 as shown, although washers could serve the same purpose as the flange 36 on the screws 34, 35.
The shank 37 of the screw 34 fits snugly in the sleeve 33. The shank 38 of the screw 34 has a diameter smaller than the sleeve 33.
In operation, the mitre box 10 preferably has one opposite roller 19, 21, 25, 27 of each roller set with the sleeves 33 fixed in position as by having the screws 34 and flanges 36 tightened against the sleeve 33 so that it cannot move. The rollers 19, 21, 25, 27 thus may freely rotate with a saw blade 39 rolling against it. acting as a guide to the saw blade 39 in the slots 12, 13 substantially tangent to the slots l2, 13.
Since various saw blades 39 may have different widths, the rollers 18, 20, 24, 26 may be adjusted by loosening the screws 35, moving the roller with the sleeve 33 over to be flush with the saw blade 39, then tightening the screw 35 so that the flange 36 holds the sleeve 33 firmly between the flange 36 and the respective uprights 16, 22 and the brace walls 14, 15.
A piece of wood (not shown) may then be placed between the selected brace wall 14, 15 and the selected clamp 28, 29, adjusted to hold the wood or other material by tightening the clamps 28, 29 along the screws 30, 30' by use of the handles 31, 32.
With the rollers 18, 20, 24, 26 adjusted. the saw blade 39 moves freely, giving a very accurate cut.
A cut through slot 12 with a workpiece clamped by clamp 29, will be at a 45 angle and match the second cut on a workpiece held by clamp 29.
Angular deviation should not affect a cut, making a good corner since the deviation should be reciprocal, still totalling a workpiece fit at 90, such as a 44, 46 cut.
Deviations may be corrected by placing two cut workpieces in the clamp 28, 29 with their ends juxtaposed and straighten them out by a few saw strokes between the workpieces.
It is usually desirable for most mitre boxes to be able to provide at least a 45 and 90 cut.
Slot 13 is set up for a 90 cut. The rollers 22, 24, 23, 25 are set up as the rollers 15, 16, 17, 19 are set up to guide the blade 39.
The workpiece though is held by the clamp 29, which also serves the double purpose of holding a workpiece for a 45 cut in slot 12 as well as holding a workpiece for a 90 cut in slot 13.
Employing clamps 28, 29, the mitre box of the present invention may be used as a corner clamp.
Openings 40, 41 in the metal base 1 1 may be used to secure the mitre box of the present invention to a work bench or other working surface.
The terms and expressions which are employed are used as terms of descriptions; it is recognized, though, that various modifications are possible.
