These extension pieces also be made of any width desired and it is not necessary that the rolls be removed from the shaft in order that: these extension pieces can, be placed therebetween. It is simply necessary to revolve the adjusters 20 to bring the connected pieces 9 out of engagement with pieces 17. after which the pieces 17 will be free from'the shaft. It will be particularly noted thatthe extension piece 9 is provided with the key-way 21 so that it fitsover the key 7 that extends substantially the length ofthe shaft5.

In order that the. proper spacing may be obtained between the divisions of rollers and between the extension pieces,'we have made.

ring. The locking ring is ofthe same diameter as the extension pieces which are of a diameter to coincide exactly with the diameter ofthe rollers and it is quite evident that any number of the rollers 8 may be used upon the shaft 5 and they may all be of a different length, dependin upon the width of the printing matter to be inked. V

Iris also evident that through-the use of our improved rollers, a difierent'number of inks may beused'of various colors to prostraightvide one run through the press printing of different colors.

The entire shaft 5is reciprocated through the medium of the usual mechahismQnot illustrated,but which is well known in the art. The driving gear 24 is ill'ustrated as being keyed-as at 25 to the outer end .of the shaft 5. It isof course understood that through the proper mechanism, the shaft 5 is rotated and reciprocated simultaneously to spread the ink evenly upon' anintermediate composition roll which distributes the ink to the typeface.

In the modifications shown in Figures 6 and 7, use maybe made of a semi-circular.

spacer 26 the ends of which may be positioned in slots27 provided for that purpose in the extensionpieces 9. These spacers may be of fixed lengths so that no measuring of the space between roller assembly need be made.

It is quite evident, therefore, that we have ployed to obtain the proper length of the sec- 7 tions of the rollers.

l/Vhiie we have illustrated and described our invent on with some degree of partlcula rity, we realize that in practice Various alter'ations thereinmayrbe made; We therefore reserve the right and privilege of chang ing th'e form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention .or the scope of the appended claims.
