Bulletin 173 Plate 1 Smithsonian Institution United States National Museum U. S. NATIONAL MUSEUM BULLETIN 173 PLATE 1 SMITHSONIAN INSTITUTION UNITED STATES NATIONAL MUSEUM Bulletin 173 CATALOG OF THE MECHANICAL COLLECTIONS OF THE DIVISION OF ENGINEERING UNITED STATES NATIONAL MUSEUM BY FRANK A. TAYLOR UNITED STATES GOVERNMENT PRINTING OFFICE WASHINGTON : 1939 For lale by the Superintendent of Documents, Washington, D. C. Price 50 cents ADVERTISEMENT Tlie scientific publications of the National Museum include two series, known, respectively, as Proceedings and Bulletin. The Proceedings series, begun in 1878, is intended primarily as a medium for the publication of original papers, based on the collec- tions of the National Museum, that set forth newly acquired facts in biology, anthropology, and geology, with descriptions of new forms and revisions of limited groups. Copies of each paper, in pamphlet form, are distributed as published to libraries and scientific organi- zations and to specialists and others interested in the different sub- jects. The dates at which these separate papers are published are recorded in the table of contents of each of the volumes. Tlie series of Bulletins, the first of which was issued in 1875, contains separate publications comprising monographs of large zoological groups and other general systematic treatises (occasionally in several volumes), faunal works, reports of expeditions, catalogs of type specimens and special collections, and other material of simi- lar nature. The majority of the volumes are octavo in size, but a quarto size has been adopted in a few instances in which large plates were regarded as indispensable. In the Bulletin series appear vol- umes under the heading Contrihutions from the United States Na- tional Eerharium, in octavo form, published by the National Museum since 1902, which contain papers relating to the botanical collections of the Museum. The present work forms No. 173 of the Bulletin series. Alexander Wetmore, Assistant Secretary, Smithsonian Institution. Washington, D. C December 12, 1938.

PREFACE Objects illustrating the development of the mechanical arts and sciences have been collected and preserved by the Smithsonian Insti- tution from the earliest period of its existence. For years this activ- ity was continued incidentally to the work of the ethnological sec- tions of the Institution in the United States National Museum. In 1884, however, acquisitions from the Centennial Exposition of 1876 had increased the collections so greatly, particularly in the field of transportation, that a section of transportation was created in the Museum. This section has in time grown in scope and size into the present Department of Engineering and Industries and includes collections and exhibits in nearly every branch of engineering and industry. The Department of Engineering and Industries is now, in effect, the national museum of engineering and industry of the United States, and in size, scope, and merit of collections and in numbers of visitors to its exhibits it compares favorably with the national museums of science and industry abroad. This comparison could readily be made more favorable were it not for the fact that the collections at present are crowded in antiquated and inadequate buildings that prevent exhibition of the material in the most appealing and instructive manner. It is anticipated that in due time modern housing for these important collections will be provided. The division of engineering, one of the four divisions of the De- partment, collects, preserves, and exhibits material illustrative of the progress in all fields of engineering and the physical sciences, includ- ing such diversified subjects as transportation, aeronautics, mining, communications, tools and crafts, timekeeping, office machines, and many others. The collections described in this catalog, compiled by Frank A. Taylor, curator of engineering in the United States Na- tional Museum, are in the group roughly designated as prime movers or power-producing devices and their accessories and auxiliaries. It includes such macliines as windmills, water wheels, steam, oil, and gas engines, and steam boilers, and it will serve as a typical example of what has been done in recording, by relics, the progress made in a fundamentally important engineering field in America. It is intended that this catalog will prove a useful guide to the collections, particularly for those who cannot visit the Museum. At the same time, it will illustrate the deficiencies of the collections and, it is hoped, enlist the aid of all who can offer information, sug- vn yill PREFACE gestions, or material for expansion and improvement. It is also anticipated that individuals, trade associations, and professional groujjs who are in a position to assist will be encouraged to con- sider seriously what aid or influence they might lend to the further development of an adequate national museum of engineering and industry for the United States, under the direction of the Smithsonian Institution. C. W. MriMAN, Head Curator^ Department of Engineering and Industries. CATALOG OF THE MECHANICAL COLLECTIONS OF THE DIVISION OF ENGINEERING, UNITED STATES NATIONAL MUSEUM By Frank A. Taylor INTRODUCTION Throughout history the changing pattern of society has been determined to a large degree by the progress made in exploiting the natural energy resources of the world and the manner in which the fruits of this energy have been distributed. When the only harness- able energy source was the muscular effort of men, the sole pools of power were in groups of men, and the leaders who sought to build wealth, culture, and government beyond the immediate primitive needs of the individual had to command the obedience of slaves.

The Standard Specifications for construction of 1896 required that a vertical curve of two miles radius be introduced between changes in gradient during construction. Such curves were important for preventing coupled axleboxes of locomotives from striking the tops of cut outs or horn blocks above and keeps below (as sometimes happened where a siding on a steep gradient joined another line without such a vertical curve).

  • Steam As a General Purpose Technology: a Growth Accounting Perspective
    Working Paper No. 75/03 Steam as a General Purpose Technology: A Growth Accounting Perspective Nicholas Crafts © Nicholas Crafts Department of Economic History London School of Economics May 2003 Department of Economic History London School of Economics Houghton Street London, WC2A 2AE Tel: +44 (0)20 7955 6399 Fax: +44 (0)20 7955 7730 1. Introduction* In recent years there has been an upsurge of interest among growth economists in General Purpose Technologies (GPTs). A GPT can be defined as "a technology that initially has much scope for improvement and evntually comes to be widely used, to have many uses, and to have many Hicksian and technological complementarities" (Lipsey et al., 1998a, p. 43). Electricity, steam and information and communications technologies (ICT) are generally regarded as being among the most important examples. An interesting aspect of the occasional arrival of new GPTs that dominate macroeconomic outcomes is that they imply that the growth process may be subject to episodes of sharp acceleration and deceleration. The initial impact of a GPT on overall productivity growth is typically minimal and the realization of its eventual potential may take several decades such that the largest growth effects are quite long- delayed, as with electricity in the early twentieth century (David, 1991). Subsequently, as the scope of the technology is finally exhausted, its impact on growth will fade away. If, at that point, a new GPT is yet to be discovered or only in its infancy, a growth slowdown might be observed. A good example of this is taken by the GPT literature to be the hiatus between steam and electricity in the later nineteenth century (Lipsey et al., 1998b), echoing the famous hypothesis first advanced by Phelps-Brown and Handfield-Jones, 1952) to explain the climacteric in British economic growth.

  • History of a Forgotten Engine Alex Cannella, News Editor
    POWER PLAY History of a Forgotten Engine Alex Cannella, News Editor In 2017, there’s more variety to be found un- der the hood of a car than ever. Electric, hybrid and internal combustion engines all sit next to a range of trans- mission types, creating an ever-increasingly complex evolu- tionary web of technology choices for what we put into our automobiles. But every evolutionary tree has a few dead end branches that ended up never going anywhere. One such branch has an interesting and somewhat storied history, but it’s a history that’s been largely forgotten outside of columns describing quirky engineering marvels like this one. The sleeve-valve engine was an invention that came at the turn of the 20th century and saw scattered use between its inception and World War II. But afterwards, it fell into obscurity, outpaced (By Andy Dingley (scanner) - Scan from The Autocar (Ninth edition, circa 1919) Autocar Handbook, London: Iliffe & Sons., pp. p. 38,fig. 21, Public Domain, by the poppet valves we use in engines today that, ironically, https://commons.wikimedia.org/w/index.php?curid=8771152) it was initially developed to replace.

  • Types and Characteristics of Locomotives Dr. Ahmed A. Khalil Steam Locomotives - Operating Principle
    Types and Characteristics of Locomotives Dr. Ahmed A. Khalil Steam Locomotives - Operating Principle: The wheel is connected to the rod by a crank. The rod is connected to the piston rod of the steam cylinder., thereby converting the reciprocating motion of the piston rod generated by steam power into wheel rotation. - Main Parts of a steam locomotive: 1. Tender — Container holding both water for the boiler and combustible fuel such as wood, coal or oil for the fire box. 2. Cab — Compartment from which the engineer and fireman can control the engine and tend the firebox. 3. Whistle — Steam powered whistle, located on top of the boiler and used as a signalling and warning device. 4. Reach rod — Rod linking the reversing actuator in the cab (often a 'johnson bar') to the valve gear. 5. Safety valve — Pressure relief valve to stop the boiler exceeding the operating limit. 6. Generator — Steam powered electric generator to power pumps, head lights etc, on later locomotives. 7. Sand box/Sand dome — Holds sand that can be deposited on the rails to improve traction, especially in wet or icy conditions. 8. Throttle Lever — Controls the opening of the regulator/throttle valve thereby controlling the supply of steam to the cylinders. 9. Steam dome — Collects the steam at the top of the boiler so that it can be fed to the engine via the regulator/throttle valve. 10. Air pump — Provides air pressure for operating the brakes (train air brake system). 11. Smoke box — Collects the hot gas that have passed from the firebox and through the boiler tubes.

A CATECHISM OF THE STEAM ENGINE IN ITS VARIOUS APPLICATIONS TO MINES, MILLS, STEAM NAVIGATION, RAILWAYS, AND AGRICULTURE. WITH PRACTICAL INSTRUCTIONS FOR THE MANUFACTURE AND MANAGEMENT OF ENGINES OF EVERY CLASS. BY page 1 / 559 JOHN BOURNE, C.E. _NEW AND REVISED EDITION._ [Transcriber's Note: Inconsistencies in chapter headings and numbering of paragraphs and illustrations have been retained in this edition.] PREFACE TO THE FOURTH EDITION. For some years past a new edition of this work has been called for, but I was unwilling to allow a new edition to go forth with all the original faults of the work upon its head, and I have been too much engaged in the practical construction of steam ships and steam engines to find time for the thorough revision which I knew the work required. At length, however, I have sufficiently disengaged myself from these onerous pursuits to accomplish this necessary revision; and I now offer the work to the public, with the confidence that it will be found better deserving of the favorable acceptation and high praise it has already received. There are very few errors, either of fact or of inference, in the early editions, which I have had to correct; but there are many omissions which I have had to supply, and faults of arrangement and classification which I have had to rectify.

  • Boilers Leture Notes VUM
    Steam Boilers Lecture Notes V Uma Maheshwar 11-11-11 Steam Boilers/Steam Generators Introduction: The function of a boiler is to evaporate water into steam at a pressure higher than the atmospheric pressure. Water free from impurities such as dissolved salts , gases and non soluble solids should be supplied to boilers. This is done by suitable water treatment . Steam is useful for running steam turbines in electrical power stations , ships and steam engines in railway locomotives. Boiler furnace fuel can use either solid , liquid or gaseous fuel: Wood, Charcoal, Coal, Coke, Oil, Municipal waste, industrial solid waste , refinery gas, rice husk, Paper sludge, Electric power Steam Boilers/Steam Generators Boilers are mainly classified as fire tube boilers and water tube boilers.
