This invention concerns an attachment device for a woodworking plane, and is further directed to a woodworking plane provided with an attachment which enables said plane to produce straight edge surfaces of various desired angles with respect to the face of a workpiece.
In the course of woodworking operations, a manually operated plane is frequently utilized to smooth or straighten surfaces, particularly the end or edge surfaces of a relatively large flat workpiece having at least one substantially straight edge. In the case of panels such as doors, and in other woodworking applications, it is often found desirable to cause the edge surface to be angled at other than 90.degree. with respect to the front or rear surfaces of the panel. It is sometimes sought to cause said edge surfaces to deviate by about 5 to 20 degrees from the 90 degree configuration initially present at the edges of the panel.
Numerous devices have been proposed as attachments to woodworking planes to facilitate the cutting of edge surfaces at accurate angles with respect to face surfaces. Such devices, however, have either been inaccurate, expensive or cumbersome to use.
Accordingly, it is an object of this invention to provide an attachment device which will enable a woodworking plane to cut straight edge surfaces of a workpiece at an accurate and adjustable angle with respect to a face surface of said workpiece.
It is another object to provide a device of the aforesaid nature of simple and rugged construction which may be economically manufactured.
It is a further object of the present invention to provide a device of the aforesaid nature which may be rapidly applied to and removed from a plane, and is simple to operate.
It is a still further object of this invention to provide a woodworking plane equipped with an improved attachment device which enables said plane to cut straight edge surfaces of a workpiece at an accurate angle with respect to a face surface of said workpiece.
These objects and other objects and advantages of the invention will be apparent from the following description.
