Abstract: Improvements in the instruments for drawing lines using grooves providing the presentation of lines that may be drawn by placing a sheet of paper over the presentation and engaging the sheet of paper with the point of a writing tool with sufficient force to press the engaged part of the paper into a selected groove and then moving the writing tool point within the line, depositing pencil lead or ink from the end of the writing tool on the paper that is pressed into the selected groove to form a line on the paper. The improvements include the provision of registration marks on a clipboard which has the presentation of grooves for lines to be drawn on the upper side of the clipboard, the registration marks acting as guidelines for the precise placement of the sheet of paper on which lines are to be drawn.

Abstract: Sheets of heavy duty sketch paper are preformed with one or more grooves in them, without requiring a flat panel sheet with grooves in it, placing a paper over that flat panel sheet, and then sketching on the sketch paper with the pencil or pen following the grooves in the flat panel sheet while indenting the sheet into those grooves as is required by the prior art. The sheets of sketch paper have the grooves therein and it is the grooves of the sketch paper itself that are followed by a pencil or pen and creating lines of the sketch on the sketch paper. The sheets of heavy duty sketch paper which have preformed grooves thereon may have many very closely spaced grooves so that there is a very fine choice for using any particular groove.

Abstract: A reusable shield for wall fixture control devices while painting the wall. It has an self-adjustable-depth feature that permits the shield to cover different types and sizes of fixture control devices that project from the wall, and can be sized to cover several such devices which have a common cover plate. The shield is shown to be made of two major parts, made either separately or flexibly joined, one of which is removably secured to the wall and the other of which is adjusted to accommodate the amount of fixture control device projection from the wall while preventing paint from entering the interior of the shield. The adjustable part is able to accommodate a side variety of control devices and is not shaped to be specific to any one device.
