FFIP B' PRINTING-PRESS ROLLER.

Application filed March 23, 1926. Serial No. 96,737.

The present invention is concerned with the provision ofa novel type of inking roller for printing presses. The roller may have a wide range of utility and be made in various sizes and styles, but I have elected to show a small roller of the type commonly employed on a small Gordon press.

These rollers are made of various well known compositions, and are rather expensive. When the rollers are used for inking small type forms, such for instance as the small type forms used in printing candy bags or the like, the centers of the rollers become rapidly'worn, and the roller must be discarded, because it is unfit for subsequently inking larger type forms.

In accordance with the present invention I provide a sectional roller so that when the central section becomes worn, it may be readily replaced without the necessity for discarding the entire roller.

Objects of the invention are to provide a sectional printing roller of this character which will be of simple, practical construction, which may be readily assembled or dis-.

assembled to permit of the replacement of worn sections, a roller which will be durable and efiicient in use, capable of being manufactured with comparative economy, and capable of being assembled or disassembled with expedition.

With the above noted and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter set forth and pointed out in the claims. The invention may be more fully understood from the following description in connection with the accompanying drawings, wherein Fig. 1 is a view partly in elevation and partly in longitudinal section of a roller embodying the present invention.

Fig. 2 is 'an end view of Fig. 1 with a portion of the retaining roller broken away and in section for clearness.

In the drawings I have used the reference character 10 to designate the usual roller core or shaft formed with projecting trunnions 11. Upon this core there is mounted the usual wooden stock 12 which ordinarily carries the composition roller. In accordance with the present invention the outer thickness of the roller is formed of a plurality of

sections

13, 14 and 15 of the usual roller composition, and these sections are firmly secured 1n place on the stock'so that they are held against axial displacement or against relative rotational movement.

I have illustrated one convenient means of securing the rollers on the Wooden stock which involves the use of hinged clamping collars upon each end of the stock. These collars are preferably formed of a pair of arcuate sections 16 of spring metal hingedly connected together at one end by a hinge pin 17 At their opposite ends the sections are iIOI'IDGCl with angularly disposed ears 18 adapted to be latched together in any approved manner. The latch illustrated includes a pin 19 carried by one ear 18 and formed with a latching extension 20 passing through an opening 21 in the other ear and hooked into engagement with said ear.

VVHin the two spring clamping collars are 1n place, the

roller sections

13, 14 and 15 will be securely held against displacement. V The collars, however, permit the-ready removal of one of the

roller sections

13, 14 and 15 in the event that one of said sections becomes unduly worn.

When printinga small job, such for instance as the advertisements for small size candy bags, only the central section 14 of the roller will engage the type, consequently this section will become worn, and under ordinary circumstances the entire roller must be discarded or is rendered unfit for printing larger jobs. With the present invention it is merely necessary to remove the central section and replace it by a new one.

This unequal wear on different portions of the roller occurs in many kinds of work. The difiiculty of wearing out a portion of the roller is almost always encountered where rule or table work are set up in the form.

Various changes and alterations might be made in the general form and arrangement of parts described without departing from the invention. Hence I do not Wish to limit myself to the details set forth, but shall consider myself at liberty to make such changes and alternations'as fairly fall within the spirit and scope of the appended claims.

I claim 1. An inking roller for printing presses including a stock, a plurality of cylindrical roller sections mounted in end to end abutting relationshi 0n the stock and means preventing aXia displacement of said sections, said means including detachable spring collars encircling the ends of the stock said collars being formed of a pair of arcuate stock embracing sections hingedly connected together at one end and detach ably connected together at their other end.

2. An inking roller for printing presses including a stock, a plurality of cylindrical roller sections mounted in end to ,end abutting relationship on the stool: and means preventing axial displacement of said sections, said means including spring collars encircling the ends of the stock, said collars being formed of a pair of arcuate stock embracing sections hingedly connected together at one end and detachably connectedtogether at their other end, the detachably connected ends of the sections including apertured ears, a securing device mounted in one opening and latched through the other opening.
