INKING-ROLLER.

.Specification of Letters Patent.

Application led October 28, 1920. Serial No. l120,158.

To all whom t may con cera:

Be it known that I, AUGUsTUs R. CoLGiN, a citizen of the United States, and a resident of the city of New York, Richmond Hill, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Inking-Roller, of which the following is a full, clear, and exact description.

The invention relates to printing presses and its object is to provide a new and improved ink'ing roller arranged to reduce the amount of the plastic composition required for forming the inking rim of the roller to a minimuml thus reducing the cost of the inking roller.

Another object is to permit of retaining the comparatively heavy spindle or stock by the printer while the lighter shell is shipped to the manufacturer of inking rollers for replacing a worn out or defective rim by a new one, thereby saving considerable 1n the expense of shippin the roller from the printer to the manu acturer and vice versa.

Another object is to permit of making the rim in sectionsfor wide inking rollers, which sections being of a length corresponding approximately to the width of a page or section to be printed.

Another object is to permit of running the inking roller at a high speed particularly in case the inking roller is of considerable length when printing a plurality of paras or sections located si e by side.

ith these and other objects in view, the invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all ythe views.

Figure 1 is a side elevation of the improved inking roller;

Fig. 2 is an enlarged transverse section of the same on the line 2-2 of Fig. 1'; and

Fig. 3 is an enlarged longitudinal section of the same on the line 3 3 of Fig. 2 and with the spindle or stock shown in elevation.

The spindle or stock l0 of the inking roller comprises an enlarged portion 11 terminating at its ends in reduced portions l2 from which extend journals 13 for engagement with the bearing in which the inking roller is to be journaled. On the peripheral face of the enlarged portion 11 are formed longitudinally extending grooves 15. in which tit longitudinally supporting bars 16 secured to the inner surface of a shell 17 concentric with the spindle 10. The shell 17 is provided at its ends with flanges 18 and on the said shell is molded the inking rim 2 0 of the roller and formed of the usual plastic composition of glue and molasses, or glue, glycerin and sugar, or other simi lar ingredients. In practice, the shell 17 is fastened to the bars 16 by rivets 21, and one o fthe bars 16 is preferably fastened in position in the corresponding groove 15 against longitudinal movement of the shell by a set screw 22 (see Fig. 3). It will be noticed that the bottoms of the grooves 15 are arranged to permit of sliding the supporting bars 16 endwise into oi' out of the grooves on assembling or disassembling the shell 17 relative to the spindle or stock. For inking rollers of ordinary length but a single shell 17 is used, while for inking rollers employed for inking wider surfaces a plurality of shells are assembled one alongside the other on the same spindle or stock, as indicated in Figs. 1 and 3.

It .will be noticed that the sections thus forming an inking roller are spaced apart by the adjacent and abutting flanges 18, and these spaces register with the margins on the paper to be printed, and hence the inking-of the corresponding cylinders at these particular points is not necessary. In case the inking rim is worn out or otherwise inf jured and needs replacement by a new one then it is only necessary to slide the shell 17 with its supporting bars 16 endwise out of engagement with the spindle or stock 10 to permit of shipping the shell with its supporting bars to the manufacturer of inking .rollers for recovering the shell with another inking rim, it being understood that the heavy stock or spindle is retained by the printer until the recovered shell is returned by the manufacturer. It will be noticed that this recovered shell can bel readily slipped in place on the spindle or stock to permit of again using the inking roller in the printing press.

a minimum and thus reduce the amount of the plastic composition required for forming the rim of the inking roller, and hence the cost in the manufacture of the inking roller is reduced to a minimum.

It will further be noticed that as the printer retains the heavy spindle or stock while the lighter shell is shipped to the manufacturer, considerable expense is saved in the cost of shipping.

It will be seen that by making the inking rim in sections a truer inking roller can be formed and one that is not liable to wabble and produce defective inking.

It will be noticedl that by the arrange nient described, air passages are provided between the spindle and the shell to permit air to circulate through the passages to keep the shell and the rim in cool condition and thus allow running of the inking roller at a hi h speed.

aving thus described my invention, I

claim as new and desire t0-secure by Letters Patent 1. An inking roller, comprising a spindle provided with reduced journals at the ends and having longitudinal grooves intermediate the journals, supporting bars fitting the said grooves and projecting from the peripheral face of the spindle,r and a shell attached to the said bars and concentric with the .said spindle.

2. Aninking roller, comprising a spindle provided with reduced journals at the ends and having longitudinal grooves intermediate the journals, supporting bars fitting the said grooves and projecting from the peripheral face of the spindle, a shell attached to the said bars and concentric with the said spindle, the shell having retaining flanges at the ends, and an inking rim of a plastic composition molded on the said shelland abutting against the said iano'es.

AUGUSTUS if coLeiN.
