Excerpt from Mechanical Drawing Working Drawings This book is designed to cover two different fields. As an elementary text-book it is complete in itself and should enable the student to make or read any simple mechanical drawing. As an introductory work, in schools that offer a three or four years' course in Mechanical Drawing, it should lay a good foundation for the subject of Projection. The drawing instruments are explained as they are introduced in the course, instead of in a chapter by themselves. Each problem is fully discussed before the student is expected to attack it. It is suggested that the student be required to work out his problem for each plate, free-hand, outside of the class-room. This will give him valuable practice in free-hand sketching, and it will save time in the class-room for needed attention to technique. The exercises in lettering (Chapter XIV), should show results in the improved appearance of all drawings made. The Geometrical definitions are usually wanting in books on Mechanical Drawing; but are inserted here (Chapter XIV). Even if not set as a lesson to be learned, they will still be found very useful for reference. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Mechanical Drawing: Lettering, Materials and Methods Broadly speaking, Mechanical Drawing may be understood to mean drawing done with the aid of instruments. More strictly, it may mean the drawing of machines or things mechanical as distinguished from architectural drawing, for instance. Mechanical drawings of machines are often called working drawings, of buildings they are called plans. Such drawings convey the ideas of the originator or engineer to the mechanic or the workman. Mechanical drawing, then, may be said to be the language of the engineer, the architect, the mechanic. The musician conveys his ideas by means of music, the artist by means of his picture. An inventor or designer often spends weeks and months on some contrivance or plan. He probably makes many calculations. It would be almost impossible for him to remember all the details and scores of dimensions, much less to tell them to some one else. The drawing then furnishes him with a means of recording his ideas and calculations and showing details of construction. The requirements of a good draftsman are neatness, accuracy and rapidity. By neatness is meant that not only must the draftsman keep his drawing clean, but he must arrange it neatly. The student must cultivate the habit of making clean, sharp lines and neat, well-arranged drawings. Unless a drawing is made in a workmanlike manner, the work on the contrivance is not apt to be performed in a thorough manner. Accuracy, too, is most important. It is evident that unless a drawing is made accurate in detail and dimensioned accurately, work made from it will not be as planned. It will often be found impossible to make the thing at all or costly mistakes will result. Much valuable time, labor, and material will be wasted because of a careless draftsman and checker. A draftsman should not only be neat and absolutely accurate, but he must be able to make a drawing in a reasonable length of time. No matter how good a draftsman may be, an employer can hardly afford to keep him unless he has a certain degree of rapidity. However, accuracy and neatness should not be sacrificed for rapidity. Rapidity greatly depends on how one takes hold of a piece of work, his order of procedure. A regular order should be acquired.

Excerpt from Working Drawings of Machinery This book has been planned especially to meet the needs of the second and third year students who are studying drawing in the Department of Mechanical Engineering at the Massachusetts Institute of Technology. The authors hope, however, that the material is of such a nature and is presented in such a way that it will partly fill the need which has always existed of a. Book devoted especially to machine drawing, suitable for use in technical schools and as a reference book for practical draftsmen. It is not an elementary text book of mechanical drawing, but rather a treatise on the application of mechanical drawing to the describing or designing of machinery.

Excerpt from Working Drawings and Drafting-Room Kinks It is not the business of the mechanical draftsman, however, to make pictures, and he seldom has occasion to draw perspective views. He has to convey his ideas by simpler methods than this, and in making working drawings uses what is called Orthographic Projection, or simply, projection. His drawing may not always look like the object, from the pictorial standpoint, since certain conventional figures and methods are adopted to represent machine parts, which can be drawn much quicker in this way than if their true form were reproduced. Thus, it is not customary to draw screw threads in the way in which they actually appear to the eye; an easier and quicker method of representing them is adopted, and the same is true of. Other parts. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from A Manual of Engineering Drawing for Students and Draftsmen Different courses have been designed for different purposes, and criticism is not intended, but it would seem that better unity of method might result if there were a better recognition of the conception that drawing is a real language, to be studied and taught in the same way as any other language. With this conception it may be seen that except for the practice in the handling and use of instruments, and for showing certain stand ards of execution, copying drawings does little more in the study as an art of expression of thought than copying paragraphs from a German book would do in beginning the study of the German language. And it would appear equally true that good pedagogy would not advise taking up composition in a new language before the simple structure of the sentence is understood and appreciated; that is, working drawings would not be considered until after the theory of projection has been explained.

Excerpt from First Principles of Mechanical and Engineering Drawing The greater part Of the subject matter Of this book appeared in a series Of articles in the Mechanical World. The purpose in writing it is SO fully explained in the Introduction that a Preface is hardly required. AS the forms given to the various parts Of a machine or engine are on analysis invariably found to be combinations Of certain geometrical Solids, a knowledge Of how each Of these Should be drawn when in any position should be first acquired by the student draughts man. TO this end a series Of problems is given in the following pages, commencing with the construction of those Simple geometrical figures which form the surfaces Of the solids which give Shape to mechanical details, and subsequently the method adopted in representing the solids themselves, singly and in combination. AS no amount Of copying drawings Of mechanical details will ever give the student a knowledge Of the reasons why they are made to take the special forms given to them, SO in the earlier stages Of the study Of mechanical drawing it is impossible for him to acquire the power to draw the Simplest solids in different positions correctly without a knowledge Of the principles Of Orthographic Projection, which is the basis Of the representation Of all solid Objects. In this part Of the subject an extended series Of problems is given, the solution Of which Should enable the student to draw any Simple Object without further help. In the method Of studying the contents Of this work, the student is advised to take the different parts Of the subject in the order in which they are arranged, as he will thereby be led to acquire a mastery Of it in a way that will impress upon his mind the connection that each part bears to that which follows. The order Of study may not be that usually followed, but it is such as an association Of many years with draughtsmen and students has proved to the author to be the best for the acquisition Of the preliminary knowledge necessary to the successful practice Of the draughtsman's art.

Excerpt from Senior Course in Mechanical Drawing: Comprising a Complete System of Working Drawings The Plates in this Course are drawn with the same conventional lines as in the preceding ones that is, the full lines and short dots represent lines of the object being drawn and are to be inked black, the long dots represent centre-lines and important bases and lines of reference and are to be inked blue, and the long-and-short dots represent construction lines used in obtaining the lines of the object, the preservation of which is desirable, and are to be inked red. All dimensions lines are red. All red and blue lines are to be full, not dotted. If, however, a tracing of the drawing is required for the purpose of obtaining Blue Prints, the lines should all be black and be distinguished as in the Plates.

Excerpt from Perspective Sketching From Working Drawings The course in perspective sketching from working drawings, outlined in this manual, is a result of the author's experience in teaching this branch of drawing to first and second year pupils in the Technical High School, Springfield, Massachusetts. It was found that many pupils who could readily make working drawings from models or sketches, did not easily recognize similar forms when embodied in more or less complicated working drawings. A series of exercises and problems in perspective sketching from working draw ings without the use of models, was introduced into the course in drawing. The result was so satisfactory that gradually more time was devoted to this subject, and it has been found that students progress more rapidly in the reading and making of complicated working drawings after completing this part of the course. The great advantage to the student in having the power to translate working drawings into perspec tive sketches is that it gives him the ability to make clear in this way the meaning of such drawings to those un familiar with them. It is not within the province of this manual to enter into a discussion of the many theories and various principles of perspective drawing. Aside from a plain statement of facts connected with the fundamental principles of perspective, the manual contains exercises and problems carefully selected in order to make suitable application of these principles in perspective sketching from working drawings.
