Mechanical Drawing Self-Taught

from the PREFACE:The object of this book is to enable the beginner to learn to make simple mechanical drawings without the aid of an instructor, and to create an interest in the subject by giving examples such as the machinist meets with in his every-day workshop practice. The plan of representing in many examples the pencil lines, and numbering the order in which they are marked, the author believes to possess great advantages for the learner, since it is the producing of the pencil lines that really proves the study, the inking in being merely a curtailed repetition of the pencilling. Similarly when the drawing of a piece, such, for example, as a fully developed screw thread, is shown fully developed from end to end, even though the pencil lines were all shown, yet the process of construction will be less clear than if the process of development be shown gradually along the drawing. Thus beginning at an end of the example the first pencil lines only may be shown, and as the pencilling progresses to the right-hand, the development may progress so that at the other or left-hand end, the finished inked in and shaded thread may be shown, and between these two ends will be found a part showing each stage of development of the thread, all the lines being numbered in the order in which they were marked. This prevents a confusion of lines, and makes it more easy to follow or to copy the drawing. [iv] It is the numerous inquiries from working machinists for a book of this kind that have led the author to its production, which he hopes and believes will meet the want thus indicated, giving to the learner a sufficiently practical knowledge of mechanical drawing to enable him to proceed further by copying such drawings as he may be able to obtain, or by the aid of some of the more expensive and elaborate books already published on the subject. He believes that in learning mechanical drawing without the aid of an instructor the chief difficulty is overcome when the learner has become sufficiently familiar with the instruments to be enabled to use them without hesitation or difficulty, and it is to attain this end that the chapter on plotting mechanical motions and the succeeding examples have been introduced; these forming studies that are easily followed by the beginner; while sufficiently interesting to afford to the student pleasure as well as profit. --This text refers to the Kindle Edition edition.

mechanical drawing problems

Mechanical drawing problems - 1917 - PREFACE This volunie is a book of examples and problems for the study of mechanical drawing. It is intended to be used under the direction of a teacher, although the ambitious and painstaking student can solve many of the problems without such aid. It aims to provide a large selection of typical drawings carefully worked out as examples, each one of , which is accompanied by appropriate problems suitable for elementary and advanced work in mechanicctl drawing. Explanations and directions are, when needed, expressed in simple and direct language, and in the fewest possible words. The principles of the construction of a drawing are shown in the exdmples inthe graphic language of the draftsman. The book is divided into three parts. The First Part gives in brief outline such matter as the student will need to know before beginning work. It contains, also, a limited number of geometrical constructions which will be found helpful in solving some of the problems given. The Second Part-the practical work-is divided into four sections, namely Projections, Developments and Intersections, Isometric Drawings, and Machine Details. Nearly all the example-drawings are fully dimensioned and, where necessary, described by explanatory notes. They are not to be copied but are intended to serve as a guide to the student when making his own drawings for which directions are given in the form of problems. In each section there are many more problems than any one student can work in the amount of time which is usually allotted to the subject of mechanical drawing, and a judicious selection must necessarily be made by the teacher to meet the individual students requirement. These problems are arranged in the order of their difficulty. The problems given in the beginning of each section are not too difficult for a beginner in mechanical drawing, while those toward the end of the sections will be found suitable for advanced students. Each section begins with problems that are suitable for Junior High Schools, High Schools, and Evening Schools, and advances gradually to problems that are more difficult of solution, suitable for Vocational Schools, Trade Schools, and Colleges. In the first three sections two problems arc given with each example-drawing, and in the fourth section, three problems are given. The problems on Developments and Intersections are suitable as an introductory course for students interested in sheet metal pattern drafting. The problems on Machine Details will form a logical introduction to machine design. The Third Part of the book contains tables and general information of use to drahmen, and to which frequent reference should be made when working problems in the second and fourth sections of the Second Part...
