Serial No. 394,364.

This invention relates to a new strip material for covering floors and other purposes and a method of ornamenting the same.

The invention relates'particularly to strip materials having painted surfaces, including those intended for ioor coverings and customarily known as linoleum, and also oil cloths and similar materials. The invention provides a method of ornamenting strip material of this character thereby producing a new type of decorative surface.

A strip material embodying the invention comprises a body and a layer of paint, all or a portion of which consists of two or more paints of different colors blended together in streaks running lengthwise of the strip. An important characteristic of the streaked layer of paint is that the lines of demarcation between different colors are throughout the length of the stripparallel to the strip or nearly so. The artistic effect of the new material is the'result of the fact that, although two or more colors may be intimately blended together, the surface presents no blotches such as would ber caused by any lines of demarcation extending transversely of vthe strip. This does not mean that each streak `of color necessarily runs the entire length of the strip, but that any streaks of color which extend less than the whole length of strip taper A off into line points to avoid all transverse lines of demarcation.

The method of making the new floor covering consists in printing on successive lengths of the strip Va, plurality of dabs or blotches of color surrounded by a base color,

in applying a brush to each length of the strip shortly after. the' colors are printed thereon and while the colors are still wet,

40 and in causing uninterrupted relative movement in thevsame direction between the brush y and the strip throughout the combined operation of printing and brushing.

The apparatus for carrying out this method includes a brushing attachment readily applicable to a block printing machine of the type customarily used in printing iioor coverings and arranged to cause an uninterrupted movement in one direction between the strip and a brush, notwithstanding the intermittent feeding of the strip which `occurs in such block printing machines. The apparatus for carrying out the method disclosed herein is claimed in a divisional application, Serial No. 593,894, filed February 18, 1932. f

rPhe accompanying drawings show, necessarily somewhat imperfectly, a strip material embodying the invention, and illustrate a specific embodiment of my apparatus for producing this material. In the drawings:

Fig. 1 is a top view of part of a partiallycompleted strip of floor covering embodying the invention; v

Fig. 2 is an enlarged partial transverse section of the floor covering taken on the right hand end of Fig. 1;

Fig. 3 is a partial side elevation of a block printing machine embodying the apparatus features of my invention and omitting parts which are unnecessary to an explanation of my invention; and

Figs. 4 and 5 show my brush attachment, Fig. 4 being an enlarged transverse section on line 4- 4 of Fig. 3, and Fig. 5 being a section on the line 5 5 of Fig. 4.

In Fig. 1 a part of the paintlayer of the floor covering is shown in completed form at the right. It will be seen that this layer includes a middle portion having a design 80 printed thereon and two edge portions having colors mixed in streaks as heretofore described. The lengths A, B of the floor covering shown in Fig. 1 show the positions in which the paint is printed an the edge portions of each length of the fl or covering before this paint has been streked by the application of a brush. The lengths `C and D in Fig. 1 show the printing of the\`centra1 design on the strip before the-paint is applied tothe edge portions of the strip.

Figs. 3, 4 and 5 show a machine for vautomatically treating each length of a long strip l of material, first, by printing a central de- 95 sign, second, by printing a background and blotches of color on the edge portions, and third by mixing the colors 'on the edge por-T' tions to produce the streaked effect, or in other words, by carrying out the process il- 100 lustrated in the succbssive lengths of the strip shown in Fig. 1.

Fig. 3 showsa block printing machine of conventional construction. Itis provided 5 with a bed 10 over which tavel Ifeeding bands 11 for intermittently moving a strip of material along Vthe bed, and with a plurality of printing heads 13. At the right-hand end of the figure is shown the customaryJmechanism for causing the intermittent movement ofthe feeding bands 11. This mecha-l nism includes adrum 14 for each and 11, carrying a ratchet 15 which is engaged by a pawl 16 oscillated by a segment gear 17 on a l5 pivoted arm 18 which is lifted and allowed to the follower 19 is ktravelling on the rising face a X- Y of the cam, and remain stationary during the remainder of each revolution of the cam. rl`he printing heads 13 are `operated intermittently by the usual cams 22 on crossshafts 23 whose movements are synchronized with those of the cross-shaft 21 of the feeding mechanism' by a longitudinal shaft 24 0 which is connected with each of the crossshafts by a gearing of the same gear ratio. The printing heads are held in raised position during the movement of the feeding bands 11 and descend to apply paint from ,their painting blocks to the Astrip material Von the bed during the periods when the feeding bands 11 are stationary.

In accordance with my invention, one of the printing heads 13a is held up by means ofV blocks 25, so that it is out of contact with its cam, which may be removed. On the crossbeams 26 of this printing head are clamped' f two frames 27 in which are journalled two

cross-shafts

28, 29, On the frames 27 are pivots 30 to which are secured the upper ends oftwo arms 31, which-depend between the cross-beams 26 through the space ordinarily occupied by the printing blocks, which; in this case, are removed. The arms 31 contain 59 slots 32 into which project crank pins 33 on disks 34 xed on the ends of the shaft 29. The lower ends of the arms 31 have a. pin and slot'connection with blocks 35, slidable on rods 3.6 carried by frames 37 clamped to the cross-beams 26, and to these blocks is pivotally attached a brush 38 `havingvseparated sets of bristles 39. The length of the brush 38 is greater than the distance' between the rods 36 and the bed 10 of the ma- I C3 chine, so that the bristles 39 rest on the strip of material on the bed in an inclined position, as shown in Fig. 5. The shaft 29 is driven from the cam-shaft 23a associated with the printing head 13a by a-pair of gears C3 40, 41 fixed on\the

shafts

29, 28 respectively,

The cam ro- 1 and a pair of sprockets 42, 43 fixed n the shaft 28 and its camshaft 23a and connected by a sprocket chain 44. The two gears and the two sprockets each have a one-to-one ratio, so that Jche rate of revolution of the shaft 29 is equal to `that of the cross-shaft 23a and lalso that of the cross-shaft 21. By proper positioning of the parts when the sprocket chain 44 is applied, the crank pins 33 are placed in their uppermost positions when the middle point Z of the rising surface X^Y of the cam is in engagement with the kover the surface of the material during the period that the material is at rest and also during the moments when the material starts and stops its movement. This result is attained because of the fact that the amplitude of the reciprocation of the brush is considerably less than the distance travelled by the material atl each movement thereof, the latter being, of course, equal to that between successive printing heads.` Furthermore, the fact that the material is moved forward during more than one-half of each revolution of the cross-shafts while the\brush is moved backward during more than one-half of each such revolution-namelywhile the pins 33 are traveling from the position 33X to the position 33Y-insures a backward travel of the brush during the moments when the material is starting and stopping. The effect of the intermittent movement of the material combinedwith the reciprocatory movement of the brush is that there is an uninterrupted relative movement between the br sh and the-material, producing the same effe t as though the brush were continuously drawn in a rearwardlyinclined position from one end of the strip of material to its other end. The continuous relative movement between the material and the brush in one di- `rection is important, since it secures the deare used to apply to thev edge portions of the strip the paints which are to be mixed and streaked by the brush which they reach before they have had timeto dry.

What l claim is: f

l. lThe method of producing an ornamental vsurface on a strip material, which comprises successivelyl printing on successive lengths of the strip paints of a plurality of colors, maintaining a brush in contact with each length of the strip shortly after the colors have been printed thereon and while the paint is still wet, and causing uninterrupted relative movement in the same direction between the brush and the strip through the operation of printing and brushing the entire strip.

2. The method of producing an ornamental surface on a strip material, which consists of intermittently moving the strip,suc cessively printing paints of a plurality of colors on successive lengths of the strip during its period of rest, maintaining a brush in contact wit-h each length of the strip shortly after the colors have been printed thereon and while the paint is still wet, and causing uninterrupted relative movement between the brush and the strip throughout the operation of printing and brushing the entire strip.

3. In the method of printing, the steps consisting in moving printed material forwardly in a step-by-step manner, moving a brush thereover, and maintaining relative longitudinal movement between the brush and the material at all times.

4. In the method of printing, the steps conlsisting in moving printed material forwardly in a step-by-step manner, moving a brush back and forth thereof, and maintaining relative longitudinal movement between the brush and the material at all times.

5. In the method of printing, the steps consisting in moving printed material forward in periods of movement alternated with pe-.

riods of repose, and moving a brush back and forth longitudinally over the material, the change in direction of movement of the brush occurring during a period of movement of the materlal.

6. In the method of printing, the steps consisting in moving material forward in a stepby-step manner and in a definite time cycle, printing on the'- material, and applying a rush to the printed surface, the' brush being moved in a different time cycle.

. In the method of printing, the steps consisting in moving printed material forwardly in a step-by-step manner, moving a blending device thereover, and maintaining relative longitudinal movement between the inaterial and the blending device at all times.

8. ln the method of printing, the steps consisting in advancing material in a step-bystep manner, printing thereon in periods of rest so as to produce a substantially continuously extending printed surface, engaging ed surface, engaging such surface with a brush and effecting substantially continuous relative movement between the printed material and the brush while maintaining a substantially constant angularity of the brush bristles.

In testimony whereof l have hereunto set my hand.
