Burgh's steam engine, 1859
In an 1859 article in ''The Engineer'' Burgh pictured and described an improved arrangement for a''A treatise on sugar machinery,'' 1863
In the preface to "A treatise on sugar machinery" (1863) Burgh explained that the work was "intended for the use of Sugar Planters, Refiners, Engineers, etc. showing the present process of producing sugar from the cane, and of manufacturing and arranging the machinery. The designs and rules are given from practice, but at the same time, may be susceptible of improvement."Burgh (1863, preface) The book was divided into three parts, which Burgh described as follows:ANALYSIS PROCESS : ... to enable correct calculations to be made, so as to determine the machinery, etc., requisite in proportion to the produce required... MANUFACTURING MACHINERY: In this part of the work the author has endeavoured to show the mode of producing effective and durable machinery of the best kind he is at present conversant with. ERECTING AND CONNECTING: ...the proper method of erecting and constructing the whole of the machinery used in the produce of sugar from the cane; but more particularly that of the sugar mill and vacuum pan, these two apparatus being the most essential.
''Modern Marine Engineering,'' 1867
An 1867 review of this work in ''Although the marine steam engine, in general, is essentially the same today. as it was ten years ago, the details of it, and the practice of today compared with thc past are so changed for the better that the mechanical portion of the community are always ready and eager to obtain a knowledge of the construction at the present time. English writers have, with a iew exceptions, supplied all the literature of the profession, and to them we look for the best works on the subject. John Bourne has rendered substantial service in this way, and there are no works on mechanical engineering more useful and reliable than his "Catechism," and later " Hand Book." We have before us a new work on "Modern Marine Engineering," applied to paddle and screw steamers, by N. P. Burgh, engineer. The work is published in England, and issued in New York by D. Van Nostrand, No. 192 Broadway.Modern Marine EngineeringThe review proceeds with a summary of the first chapter:
" in: ''Scientific American,'' Vol. 14, Issue 19, (May 6, 1866)
The first number contains drawings of a new set of engines recently built in England for a Russian frigate. These are made to scale, and accurately colored to represent the different metals employed. The colors are those generally used by the profession, not attempts at pictures. They give a clear idea of the plan and general arrangement. The style in which the work is got up challenges attention. The type is large and fine, the matter is double-leaded, and in point of mechanical execution faultless. The scope of the text is somewhat comprehensive; and in view of the interest always attaching to the subject, the reader scans every page attentively. Mr. Burgh goes into the subject quite prepared, indeed confident of his ability to cope with any question, and after discussing some of the types of engines in general use, he alludes to our forefathers as follows:
“To design engines-on land, and correctly manage, or rather attend to them at sea. would puzzle some of our forefathers, whose originations were nevertheless fair examples of that age of progression; what may seem perfection of arrangement, even after construction, on land, will often betray want of foresight as to access for repair or renewal at sea."
''The Indicator Diagram Practically Considered,'' 1869
One of the later books Burgh published was on theA detailed and influential treatment of the indicator within the framework of a newly developing 'engineering science' was given by W. J. Macquorn Rankine, in his ''A Manual of the Steam Engine'' (1859). Rankine not only reconceptualized the indicator diagram as what he called the 'diagram of energy', but also offered a substantial scientific account of how departures of real indicator diagrams from the ideal could be linked to operating characteristics of engines and of the indicator itself.More works in those days described the diagram and its origin, such as in the 1865 ''Handbook of the steam-engine'' by the British engineer John Bourne. In the chapter on "The power and performance of engines" he introduced the device and made extensive use of indicator diagrams. In the first chapter of his 1869 work Burgh gave a general description of the state of the art on this subject in those days:
A VERY large proportion of the young members of the engineering profession look at an indicator diagram as a mysterious production; and even supposing that they comprehend how it is formed, they do not understand the causes for the various forms of figures. There is, therefore undoubtedly, room for a practical work on the subject which shall deal with the matter just as a learner requires : leading him on step by step without slipping, and impressing on his mind all the realities of the case... The best course of instruction for the young engineer then is, that the truth of each minute portion of the subject before him be laid bare, so that he can comprehend it. When he understands thus far, obviously his knowledge will enable him to put the same into practice boldly : for by being acquainted with the ground-work of the subject, he is master also to a great extent of the result of his labours.In the preface Burgh explained, that the book describes all inns and outs of the PV diagram in the following ten steps:
* Chapter I. contains the description and use of the indicator, illustrating, at a working scale, Messrs. Maudslays' and Mr. Richards' Indicators (see image). * Chapter II. is under the heading, "How to take an indicator diagram correctly:" which treats of the action of the steam in the cylinder ; the definition of the diagram ; correct indicator gear for horizontal, vertical, and oscillating engines, and indicating notes. * Chapter III. deals with the proof of atmospheric pressure and particulars of steam pressures, and includes rules and tables bearing on the subject, with practical examples and illustrations. * Chapter IV. is a complete description and illustration of the theoretical geometry of the indicator diagram in a more practical manner than hitherto published. * Chapter V. is the practical geometry of the indicator diagram, which fully explains the frontispiece plate and other figures in connection with it. * Chapter VI. commences the illustrations of indicator diagrams and gear constructed by the firms I have mentioned, and others whose names are noted under the figures : this chapter contains twenty-one diagrams from ordinary modern screw engines of all classes; three from compound engines ; three of steam-launch engines ; and two illustrations of indicator gear for return acting engines. * Chapter VII. is devoted to diagrams taken from the most modem paddle-engines, and contains eighteen illustrations of them; also the most improved indicator gear by Messrs. Penn and Napier, for oscillating engines. * Chapter VIII. treats of land-engine indicator diagrams, showing eleven examples taken from various classes, including locomotive engines. * Chapter IX. fully explains and illustrates air and water pump diagrams. * Chapter X. closes this work, with the explanation of the indicated horse-power in connection with the diagram.This work was republished several times in Burgh's days. The fourth edition of this work was published in 1876, and the fifth edition in 1879.
Reception
Burgh was well known is his days. Many of the books were republished in his time. His ''Pocket-Book of Practical Rules for the Proportions of Modern Engines and Boilers for Land and Marine purposes'' even ran until the 7th edition in the mid 1880s, and his ''Engineer. King's Notes on Steam,'' reached the nineteenth edition in 1882. In the 1860s his work became internationally known. In the United States the ''... particulars and drawings of their boilers and engines are given in Modern Marine Engineering, by N. P. Burgh, published in 1872. The most original design was that of J. and G. Rennie, for whereas Penns and Maudslays both retained the locomotive boiler and non-condensing engines...Another 1940 publication in the ''Combustion'' journal mentioned that:
Most interesting treatise on boilers, by N. P. Burgh, published in 1873, has just come to the attention of the Editor. Because of the many unique arrangements therein presented, it is believed that Combustion readers will find a description of some of these designs of particular interest in revealing the ingenuity and thinking of engineers of those days.Burgh's work was not completely forgotten. Also in the second part of the 20th century references to his work kept being made. For example, in 1967 Adrian Arthur Bennett mentioned Burgh's books "Rules for Designing, Constructing and Erecting Land and Marine Engines and Boilers," and "Modern Screw Propulsion" playing a role in the introduction of Western science and technology into China in the Nineteenth-century. In 1990 Stephen Hughes referred to Burgh's correspondence on the
