PRINTERS TO THE QUEEN'S MOST EXCELLENT MAJESTY,
25, SOUTHAMPTON BUILDINGS, JOLBORN,
YEAR by year the Indexes to Patents are becoming more numerous and expensive ; and many inventors and others to whom they have become indispensable are thereby precluded from purchasing them.
To obviate this difficulty, short abstracts or abridgments of the Specifications of Patents under each head of Invention have been prepared for publication separately, and so arranged as to form at once a Chronological, Subjectmatter, Reference, and Alphabetical Index to the class to which they relate. As these publications do not supersede the necessity for consulting the Specifications, the prices at which the latter are sold have been added.
The present series of abridgments comprises only those Specifications that relate to processes for coating metals with metals. Applications in which processes have not been expressly stated are omitted ; but whenever any reasonable doubt exists as to whether a Specification should be embraced by the series or not, its abridgement is included ; thus the title “Plating or Coating Metals with Metals” has been strictly adhered to.
All inventions that specifically relate to pickling or otherwise preparing metals to be coated with metals are included in this series. These abridgments also comprise inventions that relate to combining metals that are intended to coat other metals.
Specifications that relate to electrotyping are not included in this series ; only those electro-depositing Patents which refer to coating metals permanently with metals are comprised in this work.
Specifications that relate to “ coating iron with steel,” by case-hardening the iron, are not included in this series.
All the quotations from the printed Specifications (included between quotation commas throughout the work) are given in the exact punctuation and orthography therein used; however, to draw attention to any passage more immediately connected with this series of abridgments, portions are sometimes italicised that appear in Roman type in the original.
The publication of these abridgments tends to prevent an old invention from being re-patented; it is hoped, therefore, that inventors in this portion of applied science will only exert their talents upon discoveries that are new.
INDEX OF NAMES.
The names of persons by whom inventions have been communicated from
abroad, when known, are printed in Italics. The Roman numerals refer
