NON-SKID PRINTING-ROLLER.

Specification of Letters Patent.

Patented June 5, 191?.

Application filed October 24, 1916. Serial No. 127,431.

I! aZZ whom it may concern Be it known that I, WILLIAM ScrrALLnR, a citizen of the United States, residing at Brooklyn, in the county of Queens and State of New York, have invented certain new and useful Improvements in Non-Skid Printing-Rollers, of which the following is a specification.

The present invention relates to the art of printing and has particular reference to new and useful improvements in traveling roller inking apparatus.

An object of my invention is to provide a new and improved inking apparatus for oscillating presses wherein the inking rollers first engage the surface of a plate and are then moved downwardly over the face of the type.

It is well known to those skilled in the art that in the present type of oscillating printing presses the inking rollers will skid or slide over the face of the type or over the inking plate, in the first case removing instead of applying the ink to the type and in the second case gathering too much ink at a given point on one of the rollers, tending to produce a smeared copy,

Another object of my invention is to pro vide means for causing positive rotation of the inking rollers at all times during their path of movement so that the difliculties now encountered in this type of inking apparatus will be removed.

A further object of my invention is to provide an improvement of the class described which may be easily and economically applied to any of the existing types of oscillating printing presses without materially altering the structure of the same. Of course, my invention is primarily designed as a novel construction of printing press, a printing press to be manufactured with the improvements applied thereto.

Other objects and advantages to be derived from the use of my improved inking attachment for printing presses will appear from the following detailed description and the claims, taken with an inspection of the accompanying drawings, in which Figure 1 is a side elevational view of a printing press showing my improved inking attachment applied thereto, the roller carrying arms being removed;

Fig. 2 is a front elevational view of the same, portions of the press being omitted;

Fig. 3 is an enlarged detailed sectional view of one of the inking rollers of my ingention and the guiding mechanism there- Fig. 4 is an enlarged fragmentary sectional view of a portion of the roller actuat ing rail;

Fig. 5 is an enlarged fragmentary perspective view of one end of one of the ink ing rollers Fig. 6 is an enlarged sectional view of one of the rollers adjacent one end thereof; and

Fig. 7 is an enlarged fragmentary perspective view of a portion of a removable rail for application to existing printing presses.

Referring more particularly to the drawings, wherein similar characters of reference designate like and corresponding parts throughout the various views, 10 designates in its entirety the body of a press embodying the standard construction, the same having a type chase 11 in which is mounted a page of type 12 held in position by the usual furniture 13. The ink carrying plate .is designated 14 and is of the rotatable type operated with any of the usual mechanism for this purpose. 1 v

The inking rollers are designated 15, there being three shown in the present instance. The inking rollers are adapted to move across the plate 1 and downwardly over the page of type 12 to ink the same.

My invention contemplates the provision of means for imparting rotary motion to the rollers 15 independently of the motion given the same by virtue of their contact with the type or the side rails of the press. In my improved arrangement I provide the side rails 17 and 18, the same being provided with lateral flanges 19 and 20 having teeth 21 and 22 formed thereon.

As the rollers 15 are identical in construction as well as the guiding means thereof, I shall describe but one of the same. Referring specifically to Fig. 3, I provide a shaft 24, the free ends of said shaft being reduced as at 25 to form trunnions for engagement with one pair of the roller carrying members 27. Pinions 28 are mounted 011 the free ends of the shaft 24 between the free ends of the rollers 15 and the roller carriers, said pinions meshing with the teeth formed on the flanges 19 and 20. The pinions 28 are formed with tread portions 29 adapted to ride along the rails 17 and 18. Longitudinal keys 30 are carried by the shaftQAE connecting the pinions 28 positively,

with said shaft, said keys being provided with offset portions 31 at their inner ends to be disposed between the ends of the rollers and the treadportions 29 so as to prevent contact therebetween and to prevent shifting of the rollers. i

The rails and flanges provide a front portion and top portion, the latter being designated 33, and it will be seen that the shaft 24 carrying the rollers 15 will pass up wardly over the front and top portions of the rails and the flanges, as in the usual form of press.

In Fig. 7 a section of a rail has been shown, designated 34:, provided with teeth 35 and openings 36, only one of the latter being shown. This rail may be placed on the older types of presses when it is desired to improve the same by placing my inking rollers thereon.

It will be apparent that in use the slid,- ing of the rollers 15 is practically impossible when the pinions are in engagement with the teeth 21 and 22. This arrangement insures continual rotation of the rollers and an even distribution of the ink' upon the type. I The device does not reduce the speed of operation of the press but does prevent sliding or so called skidding of the rollers when in use, this defect in printing presses often requiring considerable time to correct and then being subject to recurrence.

From the above description taken in con nection with the accompanying drawings, it is thought that a clear and comprehensive Copies of this patent may be obtained for five cents each, by addressing the what I claim as new and desire to secure by Letters Patent, is

1. In a printing press, the combination of a press body having side rails and flanges, gear teeth formed on said flanges, inking rollers, shafts carryingsaid inking rollers,

the free ends of said shafts being reduced to engage roller carrying members, key members formed on said shafts, pinions carried on said shafts and engaged by said key members, said pinions engaging said gear teeth on said flanges, and said keys being formed with offset portions to. space said pinions from said rollers.

2. In a printing press, the combination of a press body having side rails and toothed flanges, inking rollers and shafts therefor, keys on'said shafts, pinions carried by the shafts engaging with said keys, said pinions to engage said toothed flanges, said pinions having tread portions formed thereon to engage said rails, and said keys being formed with offset portions to space said pinions from said rollers.

In testimony whereof, I affix my signature hereto. 7
