106 TVood^s Inking Machine. 



The workman, in running in the table of the press, winds up the 

 weight that propels the inking roller ; and in running it out, gives the 

 motion to the several rollers, by which the ink is communicated to, 

 and distributed upon them. 



The frame of the press on which the sheet of paper is placed, 

 (called the tympan,) when raised, strikes a lever which releases the 

 catches that hold the fly-wheels, which are immediately set in mo- 

 tion by the weight on their axis, and, by their revolution, carry the 

 inking roller forward and backward over the form. 



A strap or string attached to the same barrel to which the weight 

 is suspended, but in an opposite direction, is wound up by its descent, 

 and, at the proper time, raises a lever which throws the catches into 

 their places, and arrests the motion of the wheels. 



This machine, which has also been adopted in England, is thus 

 noticed by the editor of the Repertory of Patent Inventions, publish- 

 ed at London. 



" Persons who have seen the grand rolling cylindrical presses, 

 moving by the aid of a steam-engine, and at the Atlas newspaper 

 office in particular, must have been struck by the peculiar method of 

 distributing the ink." After describing this method, he says— "now 

 the objects gained by this series of rollers — saving of manual labor, 

 expedition, and regular supply of ink, are gained also by the invention 

 under notice. The grand difference is in the primum mobile. In 

 the case we have described, the mover power is steam ; the space 

 ■ occupied is very large, and the expense exceedingly great; and we 

 have found this invention applied only in the largest establishments, 

 and to those immense rolling presses, that steam alone can work. 



"Here it is that Mr, Wood's merit begins. He has applied a sys- 

 tem of rollers, as like as possible to those we have just described, to 

 hand-wrought printing presses. The action of a part of the press is 

 made to produce the rotation of a fly-wheel, which sets in motion the 

 inking process, and its effect is exactly the same as this important 

 part of the steam press, without its expense." 



We understand, that in practice, the machine of Mr. Wood, is 

 found truly valuable ; its operation in inking, being uniform and ex- 

 pedidous, and attended by little inconvenience. — Ed.
