MACHINE FOR PRODUCING FIGURE-D PAPER Application filed November 21, 1925.

The invention relates in general to an improved method of producing a decorative surface; to the surface so produced, and the invention also relates to a machine for practicing the method. i

The invention has for its primary object the producing of a novel form of decorative surface and the production of a surface which will be pleasing in effect with an indefinite design which can be reproduced periodically along a length of the surface without its repetition being noticed.

Another object of the invention is to provide a simplified form of machine which will 5 produce economically, a novel form of decorative surface and which can be readily and simply modified to form various forms of decorative designs, all similar in character and differing from each other'in details which become noticeable only on close comparison.

The invention is particularly adapted for treating surfaces of paper, canvas and other fabrics designed for use as Wall decoration, but it is obvious that the invention is applicable for use in any situation where it is desired to modify the appearance of a painted or otherwise colored surface where a some what striping effect is desired.

In the art of printing wall paper, it is a known practice to coat one side of the paper with a layer of coloring material and while wet feed the same by means of an endless belt past a printing roller in such way that the roller will impress its surface characteristics on the wet coating, or, to feed the coated paper past a reciprocating brush to give the well known stippling effect. The present disclosure constitutes anefi'ect, a modification of 40 such known practices in that. the coated paper as it is advanced by the belt is subjected to a rapid Waving effect and is rapidly and re peatedly waved into contact with a pattern impressing instrument fixed in position above the belt. In practicing the method herein featured, the paper which is usually white, is coated with a contrasting coloring material as is usual in this art, and the coa d surface by the action described is subjected to a Sweeping action by its momentary dragging Serial No. 70,515.

action against the fixed tool and the coloring matter is thus caused to collect in piles ofdeeper shade than the spaces from which the coating has been completely or partially swept. In this way there is produced a backing of one color and irregularly shaped designs formed thereon ina contrasting color,

with each design being of difi'crcnt'shades of said contrasting color. The designs are dissimilar when considered transversely due to the variable character of the lixed sweeping tool and similar when considered longitudinally of the path of movement of the paper past the sweeping implement due to the repetition of the sweeping action.

Various other objects and advantages of the invention will be in part obvious from a consideration of the method features of the disclosure and from an inspection of the accompanying drawings, and in part will be more fully set forth in the following particu lar description of one method of practicing the invention and in the inspection of one form of paper printing machine embodying certain structural features of the invention, and the invention also consists in certain new and novel modifications of the preferred method. and other features of construction and combination of parts hereinafter set fortha-nd claimed.

Tn drawings, Figure 1 is a view in perspective showing certain elements of a conventional form of paper printing machine equipped with a color sweeping implement particularly constituting the novel feature of the machine as modified to practice the method featured in this disclosure, and

Figure 2 is a length of a wall paper printed by the machine equipped with the form of sweeping implement shown in Figure 1.

Referring to the machine shown in Figure 1, there is shown in general a relativelylong supporting frame 10, provided with an endless belt 11, trained about end drums 13 and 1-1 and preferably in a form of rubber or other pliable and flexible material belt. The upper run 15 of the belt is caused to pass over a vertically movable table 16 disposed beneath the upper run 15 of the belt and at the approximate center of the machine. The table is designed to reciprocate vertically for a relatively small distance so as to move the coated paper 17 disposed on the upper run of the belt into operative engagement with the working face 19 of a sweeping implement 20 fixed in position above the center of the belt and directly over the table 16.

The working face 19 may be formed in various ways depending upon the character of design which is desired on the strip of paper. In the form illustrated, the face 19 is formed of the edges of three contacting strips of felt secured together at their upper edges and with the lower edges 21 free. The free edges are cut irregularly to form a'wavy surface as shown in Figure l. The sweeping tool may be otherwise formed, such, for instance, as using a piece of string stretched along the bottom of the implement 20 which string causes the formation of a peculiar wave resembling a cord rope on the resulting design. A metal chain has been used to give a peculiar ring-like chain effect along the length of the paper treated. A twisted length of paper has men used and an old brush with some of the bristles stuck together with hardened paint, has given a particularly pleasing form of design on the treated paper.

The success of the operation apparently depends to a large extent upon the reciprocatory actuation of the table 16. Assuming a unit length of the paper, such for instance as the length equal to the width of the Working face 19. then in one suitable embodiment of the invention the table 16'was reciprocated four and a half times to each unit length of travel of the paper, so that presumably the paper was waved into engagement with the fixed implement four and a half times to each unit length of travel of the paper past the same.

1 For the purpose of reciprocating this table in the desired rapid vertical reciprocatory movement, it is shown secured at opposite ends in brackets 22 slidably mounted in upstanding guiding frames 23 secured in the frame 10 at opposite sides of the belt. The brackets 22, and with them the table 16, are reciprocated vertically by means of eccentric cam drives 24, positioned at opposite ends of a transversely disposed power shaft 25 mounted in the frame of the machine directly below the table.

As the paper 17 is fed by the upper run 15 of the belt, in the direction indicated by the arrow it is first coated with a layer of coating material fed thereto by the coloring roller 26,'as is usual with printing machines of this character. As the coated paper is fed by the belt past and beneath the work-face of the.

sweeping instrument, the rapid reciprocation of the table 16 therebeneath causes a waving of the flexible belt into vertical undulations which brings the paper thereon into momentary and rapidly repeated contact with the of the strip.

coating material so that there are formed piles of deeper shade than the spaces'from which the coating has been more or less completely swept. This sweeping action has the effect of repeating the design longitudinally of the strip, giving somewhat the appearance of longitudinalextending and indefinitely appearing stripes, as shown at 29, but which design is not of course duplicated transversely Having thus described my invention, I claim:

1. A machine for imposing a design on a strip of wall paper or the .like, comprising a sweeping implement fixed in position, and having a work face on the underside thereof. a travelling belt to move the paper beneath said implement, and reciprocating means acting on the belt to give the paper a movement I to and from the work face of the sweeping implement as the paper is \moved .past the im-' plement by the travel of the belt.

2. A machine for imposing a design on a strip of wall paper or the like comprising a sweeping implementfixed in position and having a work face on the underside thereof.

a travelling belt to move the paper beneath said implement, and reciprocating means acting on the belt to give the paper a movement to and from the work face of thesweeping implement as the paper is moved past the implement by'the travel of the belt. said reciprocating means having a rate of movement sufliciently rapid to cause unit distances of the paper to contact with the tool more than once.
