9 Claims.

This invention relates to a'machine for recording identifying dataon the normally unprinted surface of decorative wallpaper before any ground coat or design has been placed thereon for the purpose of positively identifying the paper by reel number, design shade, color or stock used. v

The method of impressing the desired data on the paper stock may be in conformity with the teaching disclosed in my coepending application filed February 4, 1939, Serial Number 254,709, entitled, Method of identification. However, the present apparatus is not to .be construed to be limited to this process as the apparatus is capable of broader application.

In printing wall paper, it is well known thatthe same batch of color will give different shades or hues where it is impressed on more than one reel of stock, as differences in thevstock itself give variations or changes which show up to marked disadvantage when placed .side by side on fiat surfaces. With the present invention data positively identifying the paper stock as coming from a particular reel of raw stock is possible, and insures the manufacturer, the jobher, the paper hanger and the trade in general to stock will have the identification data thereon.

While the machine whichforms the basis of the present invention is applicable for applying any desired indicia on the back of decorative papers at definite intervals from the beginning to the end of the roll, it is particularly useful in applying fugitive or non-fugitive colors in a manner which will either be completely obliterated by the application of paste to the paper or to permit the paste to cover the indicia without permitting it to penetrate through the front surface.

The manner and means of applying the indicia is of great importance to insure that suitable markings will be made without smearing the color used and in such a manner that the numbers, letters or other characters will dry instantaneously. Briefly stated, the indicia is placed on the paper by means of a plurality of resilient of spreading or filming the color.

points formed on wedge shaped base members and assembled in the form of letters or numerals so that only the tips of the characters are inked and thereafter contact and pressaga-inst the pa per which enlarges the spot or pointofcolor many times through pressure exerted on the wedge shaped base to flow the color over a large area.

Briefly stated, the salient features of themachine for accomplishing these purposes includes a reel of stock which is unwound and fed between upper and lower rollers, the lower roller being positively driven and the contact between the rollers pulls or feeds the paper therebetween. The upper roller is provided with longitudinally detachable sliding characters, as before described, and has means comprising a cam lever for raising the upper roller when stock is to be inserted between the upper and lower rollers in changing, reeling or after breakage.

A smaller longitudinal roller driven from the lower feed roller is adjustably positioned to contact. the resilient type on the upper roller as it revolves. Ink or color is applied to the smaller inking roller by means of a driven brush which revolves in a color trough. The brush is slowly rotated in the opposite direction fromrotation of the inking roller and does not contact the surface of the inking roller, the space between the ends of the bristles of the brush and the inking roller being taken up by the thickness of the color film. V

A resilient rubber strip or scraper having overfiow openings is, secured to a rod lying spaced and parallel to the inking roller for the purpose The brush is shorter than the inking roller, although the scraper films the color over the whole distance of the roller. The brush and the inking roller and the scraper areall-adjustable so that a micrometer variation maybe secured.

Also carried between the spaced plates 31 is a horizontal shaft on which is secured a brush'4l rotated by belt drive '42 from driven shaft [4. Theshaft 40 of the brush 4| is carried in sepa'rable'side bearings 43 and, as shown .in Fig. 6, theshait 40 in passing through the vertical side plates 31 does not contact the plates but is freely suspended in the cut-away portions 44 so that longitudinal adjustment of the side bearings 43may' be secured through thumb nut and screw- 45 passing through the front brace 23; 'with the thumb screws 45 engaging screw plates 46 and sidebars 41 which extend outwardly from the plates 31.

e To insure the proper positioning of the blade or scraper a longitudinal metal or fiber plate 56 extends across the length 'of the blade and is screwed through the resilient blade 54 to the tubular supporting rod 52. This plate permits the proper flexing of the edge of blade 54 in contact with the roller and gives support to the To permit excess color removed from the color roll 32 to flow back into the color bath, a plurality of slots or openings 51 are provided throughout the, length of the tube 52 and these slots lie between the tube and the wiper so that 'excess color drains through them back into the color trough. The degree of contact of the wiper blade against the-color roller is readily adjusted by means of horizontal side plates or lever mem- .bers 58 fa'stened'to the upper side of the rod 52 and bearing against vertical adjustable bolts 59 carried in U- shaped brackets 60 fastened to r the inside of ,thevertical side members 31.

The component parts of the impression or printing roll 32'form one of the salient features of this invention. By referring to the several figuresof the drawings, particularly Figs. 7, 12,

U 13, and 18, it will be observed that the periphery of the roller 32 is provided with a desired number of longitudinal cut-out, portions or slots having enlarged end openings 65'. Screwed interiorly 'on'the impression roll beyond the ends of the slots -65 are bolts 66 over which are mounted metal plates 61 which extend throughout the length of the slots with the ends of the plates resiliently mounted ,or floating on the bolts through the medium of coil springs 68 and cry of the roller 32 and the top of plates fil,

while the lower spring 69 is, positioned between the bottom of the plates 61 and the wing nut Hiscrew-threaded to the end of the bolt 66. This construction allows precision adjustment of resilient type through elongated slots in the impression roller to obtain the desired pressure causing desired flow of resilient members and color.

A pair of bars or slightly elevated side rails or guides 12 are secured to the upper side edges of the plates 61 for the purpose of retaining the interchangeable impression blocks 15. These blocks are slightly tapered from top to bottom With their offset lower edges 16 thinnedto en gage the under surfaces of the parallel spaced side rails 12: The blocks are held in firm frictional engagement with the undersides of the side rails through the mediumof longitudinal spring plates 1'! having upturned longitudinal edges 18 while being readily inserted or removed from the im pression cylinder 32 by slight downward pressure upon the type or character to overcome spring tensions in type stick and allow removal of the characters from the type stick or the addition of type to type stick.

Adhesively or otherwise attached to the top of each block is a resilient printing or impression member which may take the form shown in Figs. 15 and 1'7 of the drawings. In each instance a resilient base plate 80 made of rubber or other suitable material is formed With a plurality of upstanding cone or wedge-like base portions 8| having integral reduced diameter, pointed ends 82. A symbol, letter or number is made up of a plurality of the cone or wedge-like portions arranged in a suitable design. The modified form of impression member shown in Fig. 1'? has an upstanding resilient edge or Wedge formation 83 so that a more fully formed letter or design is impressed.

In use only the ends of the vertically extending reduced diameter tips or wedge member 82 of the impression members are inked by a gentle wiping or kissed action with the color roller 35, and on contact with the wall paper stock being fed from the reel, the ink on the tips is first impressed and thereafter the whole letter is pressed or flowed so. that a comparatively large diameter spot or impression is made which instantaneously dries and is non-smudg'y. The inherent resiliency of the tips themselves and their base cone or wedge portions 8| permit this spreading or flowing action, and, asshown in Fig. 18, the impression members extend only just beyond the outer periphery of the impression cylinder, although this distance is adjustable by means of the wing bolts 66.

To insure that the web or stock 2 will be evenly fed through the machine and also that any slack will be automatically compensated for a web tensioning device is pivotally attached to the vertical side frames 6. The web tensioning means comprises a freely rotatable bar 90 secured at its ends to pivoted side frames 9|, and is suniciently fore any pull occurs on the web between the bar and'the reel '2 and thus. the resultant snap or back lash is neutralized and the web prevented from breaking. I

In initially threading the stock through the machine the operator raises handle 95 having an integral cam 96 thereon.
