Book excerpt: Excerpt from Field-Manual for Railroad Engineers Chapter I gives briefly the general method of making Re-connoissance; Chapter II treats of Preliminary Surveys; while Chapter III relates to Location. Chapter IV, on Transition-curves, follows the method adopted by Professor Crandall, and enables one to locate the transition-curve with rigid accuracy where such is necessary. Approximate methods are also given by means of which the curve may be as easily located as any of the more limited easement curves ordinarily met with. Chapter V, on Frogs and Switches, contains all that is necessary for their location. The formulas have been arranged to give the desired quantities in terms of the frog number whenever the resulting equations would be easier of application than the trigonometric ones usually given. The turnout tables are unusually full and give not only the theoretical lead but the stub lead as well, from which the practical lead can be at once found when the length of switch-rail is known. Chapter VI, on Construction, tells how to set slope-stakes, and gives simple methods for computing areas and volumes either directly or by the use of tables. A short table of prismoidal corrections is given for end sections level, and also a formula for three-level sections, by means of which a suitable table may be computed if desired. The tables at the end of this book have been arranged with a view to ease of reference, for, whatever the character of the text, the chief value of a field-book must depend upon the ease with which the tables may be consulted and upon their extent and accuracy. Table IX - Functions of a One-degree Curve - separates the logarithmic functions on the one side from the natural functions on the other and will be of assistance in locating these tables. Table XVI - Transition - curve Table-reading lengthwise of the page, likewise serves to separate the trigonometric tables from the miscellaneous tables that follow. Some engineers object to the use of logarithmic tables in the field, but for them the natural functions are at hand; while for those who prefer logarithms the five-place tables of logarithmic sines, cosines, etc., will be found easy to consult and interpolate between.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Field-Manual for Railroad Engineers Ease of reference and uniformity of notation are essential in a book that is to be consulted in the field. With this in mind an effort has been made in the following pages to secure a systematic arrangement of the subject-matter and uniformity of terms and notation. Except for a few cases Greek letters have been avoided and a single letter is used to designate an angle. In so far as practicable each figure is intended to be self-explanatory, so that the explanations necessary in connection with the problems have been reduced to a minimum. Algebraic equations stand each in a distinct line, thus rendering them more easily read. A knowledge of the elements of geometry and trigonometry has been assumed, and only in the derivation of a few formulas in connection with the theory of transition-curves will any higher mathematics be needed. But these formulas may be accepted by the reader who is unfamiliar with the calculus without in any way affecting his ability to understand their applications or to follow subsequent reasoning. One can most readily turn to what he wants in a book after hav ing become familiar with its contents in the classroom. Keeping this in mind this book has been written so that it may be used as a text as' well as for reference in the field. Wherever practicable solutions to problems have been given in a rigid, general form, followed by illustrative examples, so that the student need not lose 'sight of the principle involved while following the solution for a particular case. Wherever approximate solutions seemed preferable they have also been given and their limitations pointed out.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Railroad Field Manual for Civil Engineers This book is for field use rather than for office use, though it is adapted to a large percentage of office work. It is made on a new plan which is not expected to gain immediate favor but which it is hoped will eventually appeal to railroad engineers as sensible and worthy of adoption, because its use will save time and lessen the liability of error. The degree is divided decimally instead of sexagesimally. When the author was a young man engaged on railroad location he knew one or two engineers who had one vernier of their transits graduated to read hundredths of degrees for greater convenience in setting out curves. They would have done all their work in decimals if tables had been available. When the author was planning this book he gave much thought to the question of the division of the degree and the forms of the tables that would be most convenient and time saving for the field men who might use the book. He remembered that in practically every curve problem it is necessary at some stage of the solution to transpose from minutes and seconds to decimals of a degree or vice versa. He remembered that to lay out subchords would require much less mental effort if the transit were divided to read decimals of degrees rather than minutes. He wrote to a half dozen of the leading instrument makers to learn what would be the cost of changing the verniers on an old transit to read decimals of a degree and to know whether there would be any difference in price between two instruments ordered new, one to be divided in the usual way and the other divided to read decimals of a degree. All but one of the makers gave a price in the neighborhood of $20 for changing the verniers on an old instrument, and no difference in cost for new instruments. The author then wrote to about fifty engineers, chief engineers of railroads, independent practicing engineers, and professors of railroad engineering in colleges and asked their opinions as to the desirability of a change in practice from sexagesimal to decimal division of the degree, and whether or not a table book based on the decimal division would help to bring about the change, if desirable. All but one of these engineers replied that the change is desirable. The one was a professor of railroad engineering.

Animal Transportation In April, 1899, the Chief of Engineers directed the Commandant of the Engineer School to enter upon the preparation of an Engineer Field Manual. At the same time all officers of the Engineer Corps who had been in the field during the Spanish war were invited to contribute data and suggestions, and many of them did so. At the Engineer School the work of compilation was committed to the instructor in civil engineering, then Capt. Henry Jervey, and under his control, and mostly by his own hand, a general plan of a manual was worked out, manuscript and plates prepared on the subjects of reconnaissance and bridges, and more or less complete notes on roads and railroads.

Book excerpt: Excerpt from Wire Entanglements: Addenda No; 1 to Engineer Field Manual 1. The object of these notes is to standardize the construction of obstacles throughout the American Expeditionary Forces and to limit the patterns taught and used. Such portions of previously published works on wire entanglements, as conflict with these notes, will not be used by the troops in France. 2. To insure that all training is directed to the same purpose, these patterns of entanglements and the drills for erecting them will be standard and will have the force of regulations. Units are forbidden to adopt any other types without previous sanction. If any better type or drill is discovered, the fact should be reported. The new method will then be thoroughly tested and if found more satisfactory, will be officially substituted for the old one, and all the units in training will be so informed. 3. If the occasions demands it, these standard obstacles may be modified to suit such conditions as may arise, due to lack of men, materials, etc., but only by the substitution of smooth for barbed wire, the use of wooden pickets for screw pickets, or the omission of portions of the obstacle, such as one of the aprons of the apron fence. Men trained according to the standard drills should be able to construct the modified entanglements without special practice. 4. The following are the patterns adopted: (1) Belts of ribard wire. (2) Low wire entanglement. (3) Double apron fence. (4) French high wire entanglement. (5) Portable wire obstacles. Troops will be trained in the construction of the ribard wire, the low wire entanglement, the double apron fence and portable wire obstacles. The French high wire entanglement is included in this book for the use of troops serving on the French front. General Principles 5. Location. Barbed wire entanglements should be located in accordance with the following principles: (a) They must be covered at every point by our own rifle or machine gun fire, either frontal or enfilade. Special emphasis must be laid on Flanquement, that principle which consists in so siting the entanglement and machine gun positions in reference to each other that the front of the entanglement is swept by the fire from the machine guns.

Book excerpt: Excerpt from Practical Mining: A Field Manual for Mining Engineers; With Hints to Investors in Mining Properties The percentage which is realized from an investment is governed to some extent by the nature of the security. If it is such as is not liable to much fluctuation, it is sought for permanent investment, even at a low rate of interest. Generally we may I say: The profit to be expected from any investment should be commensurate with the risk taken. People who are glad to realize 5 per cent on real estate will expect to realize 25 to 30 per cent, and often more than this amount, on a mining venture, as it is called; and it must be admitted that it is not too much for a purchaser of mining-stock to expect under existing conditions: but the intelligent operator, not in mining stock but in mines, will be satisfied with less. Naturally, a mining investment should be expected to pay a much higher rate of interest than real estate or railway securities, because it is less permanent.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Standard Forms of Field Notes for Civil Engineers The object of this book is to present forms for notetaking, and such necessary instructions in the use of them, that an engineer can take a complete set of notes and record the results of a survey in neat and workman-like manner. In all the books dealing with Surveying.and Railroad Location very little space has been given to the art of recording notes. An engineer who has worked long in the field will gradually develop a system of note-keeping which he will follow in a general way time after time; yet he will sometimes vary from his form in a few minor instances just enough to confuse a draftsman. As for the younger members of the profession, it is often hard for them to record the results of their surveys in such a manner that they can translate the notes themselves, unless they are plotted while the survey is still fresh in their minds. It is a very common thing to see an engineer called into the office to explain his notes to the draftsman; or a party returned to the field to get information which should have been taken in the original survey. An engineering party can be placed in the field and maintained only at a very large expense; and speed and accuracy is demanded by every employer.
