Abstract
This invention is a device which enables one to layout sheet metal elbows of many sizes, degree of angle, segments, and throat radiuses. Further this invention is a device for laying out round pipe sections to intersect another round pipe at a right angle either on or off center of the pipe being intersected to form a sheet metal T joint of many sizes and combination of sizes. Another advantage is the use of the transparent, rectangular, plastic elements, when one element is affixed upon the profile of an object to be intersected the lines required in this method of layout can be readily ascertained, thus eliminating the drafting of same. The gist of this invention is a layout device, and method which enables one to layout hundreds of sheet metal objects in much less time and without the preliminary procedures which are often used in this type of sheet metal fabrication.
