 moved litde more than its own breadth, 2d, Supposing thf| 

 inking table retained, as the method best suited for fine print- 

 ing, the long rack-work may be superseded by a short one, and 

 the necessary extent of movement effected by the use of wheels 

 and pinions, or by pulleys and bands, — the diameters of the pul- 

 l^s being so proportioned as to increase the motion ; and here 

 it may be observed, that it may probably be found advisable iu 

 all cases to interpose pulley and band between the toothed work 

 and the inking table, to free it as much as possible from tremor. 

 Sd, Instead of the long rack-work, circular work may be used, 

 either by using alternately the outside and the inside of a toothed 

 circumference, as is done in the Patent Mangle, or by using two 

 wheels, moving in opposite directions, having teeth on one half 

 of their circumference, acting on two lines of rack-work ; and if 

 ' multiplying pulley and band work were interposed between these 

 wheels and racks and the inking table, they might be reduced

}r With regard to the contrivance for working the press, I may 

 'jol)serve, that the excentric wheel has the advantage of a motion 

 , islow and powerful in proportion, at the first, in order to over- 

 pcome the vi^ inert'icB of the apparatus of the press, and also at 

 ^tfhe point of greatest pressure ; while it is quicker in the ijciiddle 

 parts of the action, both in the rising and the falling of the 

 press.; and the resistance of the wiper in throwing the work out 

 of gear, would serve to exhaust the momentum of the excentric 

 wheel, its axles, &c. %^C7-— —••'—'- -^--^^^ 



In the Sketch, the shaft for putting the press in motion is 

 supposed to pass right over the press, and the excentric wheel 

 i*!to act directly on the spindle of the press ; but it is evident the 

 *^^ect may be obtained by the intervention of a lever at what- 

 ever distance the shaft may be; and so the contrivance may be 

 .^suited to any situation, and, instead of acting on the spindle, it 

 jrjjiight be arranged to move the bar of a common ^press* 

 -^"'H When a few impressions or proofs merely are wanted, the ink- 

 ' fog apparatus need not be used, the hand-roller, used in thecom- 

 ^jnipn way, serving instead ; and as the inking apparatus and that 

 for working the press hf^ve no connection, one or other, or both, 

 IBay be used at pleasure ; and if the press were fitted with a bar.
