THE PRACTICAL MODEL CALCTJLATOR, 



For the Engineer, Machinist, Manufacturer of Engine Work, 

 Naval Architect, Miner, and Millwright. By Oliver Byrne, 

 Compiler and Editor of the Dictionary of Machines, Mechanics, 

 Engine Work and Engineering, and Author of various Mathe- 

 matical and Mechanical Works. Illustrated by numerous En- 

 gravings. To be published in Twelve Parts, at Twenty-five 

 Cents each, forming, when completed, One large Volume, Octavo, 

 of nearly six hundred pages. 



It will contain such calculations as are met with and required in the Me- 

 chanical Arts, and establish models or standards to guide practical men. The 

 Tables that are introduced, many of which are new, will greatly economize 

 labour, and render the every-day calculations of the practical man comprehen- 

 eive and easy. From every single calculation given in this work numerous 

 other calculations are readily modelled, so that each may be considered the head 

 of a numerous family of practical results. 



The examples selected will be found appropriate, and in all cases taken from, 

 the actual practice of the present time. Every rule has been tested by the un- 

 erring results of mathematical research, and confirmed by experiment, when 

 Buch was necessary. 



The Practical Model Calculator will be found to fill a vacancy in the library 

 of the practical working-man long considered a requirement. It will be found 

 to excel all other works of a similar nature, from tiie great extent of its range, 

 the exemplary nature of its well-selected example, and from the easy, simple, 

 and systematic manner in which the model calcnlatu'ns are established.
