"Mechanical Drawing Self-Taught" is a book written by Joshua Rose, a renowned American artist and educator in the late 19th and early 20th centuries. The book, first published in 1887, is a comprehensive guide aimed at teaching individuals the art and skill of mechanical drawing, particularly for those interested in engineering and industrial design. Key features of the book include: Fundamental Principles: The book covers fundamental principles of mechanical drawing, emphasizing precision, accuracy, and clarity. It introduces readers to the basic concepts and techniques needed to create accurate technical drawings. Step-by-Step Instruction: "Mechanical Drawing Self-Taught" provides step-by-step instructions and exercises to help readers develop their drawing skills progressively. The approach is designed to be accessible to individuals learning on their own, without the need for formal instruction. Practical Applications: Rose's book goes beyond theoretical concepts and includes practical applications of mechanical drawing. It includes examples and exercises that are relevant to real-world engineering and design scenarios, making it a valuable resource for those entering technical fields. Illustrations and Diagrams: The book is richly illustrated with numerous diagrams and drawings to visually explain the concepts being discussed. This visual approach is beneficial for learners, as it provides clear examples of how to apply the principles of mechanical drawing. Geometry and Projection: The book covers geometric principles and projections, essential for creating accurate representations of three-dimensional objects on a two-dimensional surface. This knowledge is crucial for anyone involved in technical drawing and engineering design. Universal Applicability: "Mechanical Drawing Self-Taught" is designed to be a universal guide applicable to various branches of engineering and design. It is not limited to any specific industry, making it versatile for a wide range of readers. Joshua Rose's book played a significant role in the education of individuals interested in technical and mechanical drawing during the late 19th and early 20th centuries. While it may be considered a classic in the field, readers today may find it interesting for its historical perspective and foundational insights into the principles of mechanical drawing.

Mechanical drawing self-taught comprising instructions in the selection and preparation of drawing instruments. Elementary instruction in practical mechanical drawing. Together with examples in simple geometry and elementary mechanism, including screw threads, gear wheels, mechanical motions, engines and boilers (1887). This book, "Mechanical drawing self-taught," by Joshua Rose, is a replication of a book originally published before 1887. It has been restored by human beings, page by page, so that you may enjoy it in a form as close to the original as possible. Includes unique illustrations!

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 aninterest in the subject by giving examples such as the machinist meets with in his every-day workshop practice. The plan of representing in manyexamples 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. Similarlywhen 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.

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.

Mechanical Drawing Self-Taught; Comprising instructions in the selection and preparation of drawing instruments, elementary instruction in practical mechanical drawing; together with examples in simple geometry and elementary mechanism, including screw threads, gear wheels, mechanical motions, engines and boilers, has been acknowledged as a major work throughout human history, and we have taken precautions to assure its preservation by republishing this book in a modern manner for both present and future generations. This book has been completely retyped, revised, and reformatted. The text is readable and clear because these books are not created from scanned copies.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This book is as useful today as it was over 100 years ago. It was written then to give machinists practical instruction on how to design and construct patterns; in doing so it describes the actual pattern shop practice of the late 19th century, using the terms and methods of that period. Joshua Rose explains the various types of patterns, how they are constructed, and the tools that are used. This is a reprint of the sixth edition, which gives some indication of the popularity of the book among late 19th century practitioners.
