FRANCIS J. oARaoLL, or" memes; a e ting-Eras Application filed December 14. 1931. Serial No. 580,970.

This invention relates to printing rollers for use in rotary printing machines employed in the textile rinting art and has for the primary object, t e provision of a device. D of .the above stated'character which will be efficient in operation, light in weight, and which may be manufactured at a low .cost

and consist of an outer seamless shell of non-:

ferrous metal filled with an inert material 19 under pressure so as to reinforce the shell and provide the same with sufficientv strength to withstand forces acting thereon and to provide the device with abore of the desired mandrel size, thereby rendering the device interchangeable on mandrels of a givensize. With this and other objects in view, this invention consists in certainnovel featuresof construction, combination and arrangement of parts to'be hereinafter more fully described and claimed. V

For a complete understanding of myinvention, reference is to be had to the following description and accompanying drawing, in which 7 Figure 1 is a sectional view illustratinga printing roller constructed in accordance with my invention.

Figure 2 is a sectional view taken on the,

line 2-2 of Figure 1. v s Figure 3 is a transverse sectional view illustrating a modified form of my invention. Referring in detail to the drawing, the

numerall indicates a mandrel of a rotary H printing machine on which a roller 2 is mounted and the latter includes an outer seamless shell 3 of non-ferrous material preferably constructed from copper and on which is formed the desired design to be printed on textile or fabric. An inner sleeve 4 is arranged concentrically within the outer shell 3 and provides abore to receive the mandrel 1 and may be provided with a key to fit the.

keyway of the mandrel. Spacing disks 5 are arranged betweenthe inner sleeve and the shell 8 and are secured to said sleeve and shell in any suitable way such as welding.

The end disksform heads for the roller.

j During the construction of the roller 1,

inert. material 6 is placed within theshell 3 r under pressure lSO PIOVIdG a reinforcement for" I duced,

advantage 'both'to the engraver and the the shell so that the latter is capable of withstanding forces acting thereon. The material 6 also forms the bore to receive the inner sleeve 4 or if desired the inner sleeve 4 may be omitted and the boreformed by the mate- .65

rial filming of sucha size as to receive a mandrel either of the cylindrical or cone type. I When-the sleeve iris omitted, radially'disposed reinforcing-elements 7 are embedded within'the inertmaterial 6 and preferably I are of non-ferrous material.

A roller constructed in accordance with the foregoing may be manufactured at a much lower cost than the conventional type of roller now in use and whichis constructed from-' solid metal, also this construction produces a lightness in weight which is advantageous in handlin and shipping due to the fact that the cost of shipping will be materially re- A roller constructed in accordance with the foregoing will have no internal strains set up therein,thus eliminating distortion and it can be seen that noturning is necessary to .true the roller beforeengraving the outer peripha-7 ery of the shell, and thelack of distortion will permit theroller torun equally true on a cone or on a mandrel, thus having a distinct printer. w A roller constructed in accordance with the foregoing will have .a' much lower cost of maintenance than the conventional type of; rollers'and it is tobe noted thata pattern engraved onthe outer circumference of the -8 shell may be turned off and another pattern substituted therefor when desir'ed,it being understood'that-the outside of the shell may be built up to its original circumference, thus I rendering a substantial saving to. the opera ator in cost. a While I have shown and described the pre-' ferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of 1 parts may be made without departing from the spirit and scope of my invention, as I claimed. i

Having thus described my invention, what I claimisf y A printing roller, comprising an outer seamless shell of non-ferrous material adapted to have a design applied to its outer face, an inner sleeve arranged concentrically Within said shell to rotatably receive a shafting, a filler of an inert material placed between the sleeve and shell under pressure, and discs secured to said shell and sleeve and embedded in the filler to reinforce the latter and to support the outer shell relative to the inner sleeve.

In testimony whereof I afiix my signature.
