PRINTING ROLLER Filed Oct. 5, 1950 INVENTOR ATTRNEY Patented May 9, 1933 UNITED `STATES CHARLES G. HAMPsoN, or JAMAICA, NEW YORK PRINTING ROLLER.

Appncation med october s, 1930. serial No. 486,147.

The invention relates to an improvement in printing surfaces of the type employed to distribute color in different designs on wall paper, fabrics, metallic surfaces., painted Walls and the like, hereinafter re-V ferred to .collectively as paper.V VIt is a usual practice in the printing. art to canse the paper, fabricor other material to :be printed 19 with sui-table rollers for distributing colorto a printing roller which in turn impresses its design upon the material passed through the machine. In .other cases, it has been known `to utilize hand implements for creating decorative designs and other surfaces on thick Vstructures such as walls and ceilings.

The invention herein disclosed relates parf-.ticularly to the printing surface itself designed for adaptation to both the roller vtype 2Q form .in .either a machine `or in the hand implement and to the Vflat form, and the inven- 'tion particularly features a readily demount-v able and replaceable form of printing surface which may constitute a replacement on the usual printing rollers or on the hand implement .as the case may be land following conventional practices in this respect.

The primary object of the invention is to provide -a Vsimplified form of printing 0 surface which can be easily vand cheaply formed to give any desired design or appeara'nce to the printed Surface and which wilfl :be unusually vrugged and capable of a longer Ylife than is usual with similar known constructions. l

` present invention particularly features the provi-ding of 4a printing surface which will give a mottled, stipp'led, irregular appearance or which will give a design 0 of a vmore regular appearance, and which may contain either sharp or blurred outk linesy as desired.

Various 4other objects and advantages of the invention will be in part obvious from an inspection vof the accompanying drawing ,and in part will be more fully set forth 'm .the following particular description of two forms of mechanism embodying the invent'ion, and the invention also 4consists in certain new and novel features of constructo be passed through a machine provided tion and `combination of parts hereinafter set forth and claimed.'

In .the accompanying drawing;l Fig. 1 is ya perspective vie-W of one 1.611,11-r` bodiment of the invention illustrated in eenr-A nection with the printing roller element of a conventional form of paper printing Inachine;

F 2 is a showing yof a modified embodimenst of the invention insofar `as ,the print-` 09 Y ing surface is concerned and illustrated in connection with a hand manipulated implement 0r tool; Y v .i

Fig. 3 is, an enlarged detail view .of one of the filled design forming frames shown in 05 Fig. 1;` i

Figa is an enlarged, transverse sectionf taken through one Yof the de signvf-rames of Fig. 1 and showing approxi-mately .the construction as Vtaken on the line .of this 'N figure-5 and Fig. 5 is a similar view showing a different form of Vframe and its contents and taken on the line 5 5 of Fig. 1.

Refer-ring .to the gd-'sclosure in Fig. 1, there 7.5 is shown, as part of a printing machine',fa. wooden roller 10 mountedon `a driving shaft 11 and which roller 1 0 is covered by a. cy.-4 lind-rical sleeve 12 constituting lone .physical embodiment of the invention. Referring to Q0 the disclosure `in Fig. 2, there yis shown a wooden support 13, in this case ,sho-write be a flat `block provided with :a 'handle 14 and suitably fastened to which is a sheet .of

molded soft or semi-soft rubber o r paper 815.

15,` vconstitu-ting a printing surface corresponding in function `to the cylindrical surface 12 shown in F ig. L1. i

The sleeve 12 is formed .of soft or semisoft rubber, paper or other suitable mold.- 9.9. able material, as is also the block 15 ,and in both Figs. 1 and 2 there isrshownI printing studs or projections 16 formed integral-with the support 12 or 15 as the case may be and having outer faces 17 which l.may be flat but 9,5 preferably are tangent to the ysurface .ofma cylinder enclosing the cylinder 12' in the case of Fig. 1, or parallel to the top of .the block 15Yas in Fig. 2. These projections 16 may be'vrelatively long compared to their 100 other dimensions or may be short as in some of the projections 16 but in either case,

distinguish from the known forms of rubber faced type Ain that they are easily distortable while in use and will thus impress upon the printedxsurface a different appearance than would be the case if the projections evenfthough made of rubber were so rigid as to be unyielding or substantially so. It is within the scope of the disclosure to provide the printing roller with a plurality of spaced apart projections of th'is type capable of relative movement as they are brought into engagement, with the surface under treatment thus forming a peculiarly appearing. distortable character of stippled surface. The projections may be grouped to form blotches or irregular groups of designs or to form some more positively defined design as may be desired.

YIt is obvious that under some conditions the formation of the projections 16 as integral parts of the soft, semi-soft rubber or paper base portions 12 or 15 would provide a rather weak connection between the projections, especially if they were of material length and easily bendable and are thus liable to become damaged or even broken away from the 'base portion under-the action of the high pressures used in printing operations. It ,is accordingly suggested hereinthat the base portion 12 be formed of some Vmaterial 18 (Fig. 4), such for instance'as wood or other material into which could be driven a brass frame 19, or it may be some rugged moldable material such as the hard rubber 2O (Fig. 5) into which the brass frame 19 might beset during the molding operation. In the disclosure in Fig. 1, the frames are shownincorporated into the softvrubber sleeve `12 so that there is disclosed in the severel figures the concept of mounting the frame 19 more or less rigidly in different characters of supporting structure. i

The frame 19 may be of any desired configuration to give the required outline of designand is formed preferably of an endless strip of thin brass strip which can be bent'easily into the desired outline. In the event that the brass frame is driven into the wood or other support, as is shown in Fig. 4, it must of course have sufficient mass and rigidity so as not to be distorted in the'- act of hammering it into place, but where this frameis otherwise fastened as by molding it in place as shown in Figs. 1 and 5, an extremelyv thin gauge of brass strip may be utilized and this would be particularly true where it was desired to use the exposed edge of the frame Vas part of the printing surface as would be the case in the showing in Fig. 4.

, In' the formishown in Fig. 4, the brass frame is filled with a material capable of receiving color from the color rollers or equivalent color supplying agency and to apply the color to the surface under treatment. Fig. 4; is filled with a. body of felt or paper 21 which has been tamped into position or otherwise compressed, level with the top edge 22 ofthe frame so-as to provide within the design outlined by the frame a felt or soft material printing surface 23. It is obviously within the scope of the disclosure to position within the frame 19 other forms of printing material such for instance as sponge rubber, fabric, paper and the, like, the frame providing rigidity of outline and thus preventing the spreading of the more or less loosely packed material 21. In the showing in Fig. 5, the. printing For this purpose the frame 19 in agency is in the form of a block 24;' of moldl able material such as soft rubber or paper. This comprises a massive base vportion 25 which extends above the top edge of the outlining frame 19 and from the top surface 26 extends one or more printing projections 27. The top surfaces 28 of these'projections provide printing surfaces and may be of various `forms and are so grouped both with reference to each other and with reference to vthe corresponding projections at. other parts of the entire printing surface to give the desired design and appearance to the entire kprinted surface. f

Instead of the flat printing surface shown at 28 in Fig. 5, it is suggested that the printingV surface be defined by a depression 29 forming a suction cup outlined by a thin edge 30 which may be of circular form as shown in Fig. 3, ofv triangular form as shown at 31 in Figs?) and 5,.or of'. any other geometric or irregular form'which may be selected by the artist in designingthe appearance of the finished surface. v

The printing surfaces may be Vmolded in one operation to give the all-rubberform shown in Fig. 2 or it may be made up into sheets which are cut to size and conventionally fastened to the supports l0 or y13. When a plurality of rollers or blocks lare lio used to impress dierent colors on the printed surface, the printing surfaces herein disclosed may be duplicated and placed in proper position on the several rollers.

It is obvious from this disclosure that a variety of stippled, blotted, mottled, vfine line, coarse line and dotted area a pearances may be given to the printedsur aces. The use of the design forming metal frame herein featured is particularly Valuable in that it can give rigidity and strength to what would otherwise be an extremely delicate andY easily distortable form of printing surface and at the same time there is retained the advantages of suchsurfaces when made of material such as soft, semi-soft rubber or paper.V While the top edge of the'frame as shown in Fig. 4 will give a similarly sharp and denitely defined outline to the printed design, the other printing projections herein disclosed are characterized by their ability to give or distort under pressure and will form a character of design which is more indefinite in outline than is the case where the conventional forms of printing surfaces are used. In the printing of surfaces such as wall paper and fabrics, some novel effects have been produced by an artistic grouping of sharply defined lines and areas with the less sharply defined lines and areas capable of being produced by utilizing the flexible soft rubber and similar tips andy projections featured in this disclosure.
