The drawing or drawings come first and these are made on white paper the thickness of Bristol board and the size of the sheet must be exactly 10 by 15 inches with a line drawn 1 inch from the edges all round making the sight, that is, the space in which the drawings are placed, exactly 8 by 13 inches. A reduction of a sheet of drawing for the author’s revolving arc for his wireless telephone is shown in Fig. 78.
The drawing or drawings, there may be one or more on a page and several pages if needs be, must show every detail covered by the specification and claims. The drawings may be made in isometric perspective as described in Chapter II, or plan or elevation views can be used, or both of these kinds of drawings as long as the pictures show exactly what the invention consists of and how it works. Usually the different parts are numbered and these are referred to in the description of the invention.
Should your invention be an electrical one, then a diagram of the apparatus formed of symbols (see [Chapter II]) should be used.
The specification, the front page of one of which is shown in Fig. 79, is that part of a patent which describes your invention or discovery and it should be as full and as clear as you and your patent attorney can make it and yet it must be concise and to the point.
