SPECIFICATION forming part of Letters Patent No. 527,976, dated October 23, 189 4.

Application filed October 3, 1893- Serial No. 487,120- (No 1110661.)

To all whom it may concern:

Be it known that I, RUDOLPH HEILMANN, a citizen of the United States, residing in New Brunswick, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Machines for Making Wall-Paper, of which the follow ing is a specification.

Heretofore wall papers have been made by a hand process, which consisted in providing a suitable pattern block with color by hand and pressing this block upon a sheet of paper and repeating this operation a number of times until the desired colors had been printed; and wall papers have also been made by a continuous process in which the colors were successively printed in a single operation on the paper.

The object of my invention is to provide a new and improved machine in which the colors can be printed separately by means of a straight block, upon a strip of paper which is shifted after each impression and is passed through the machine as many times as there are difierent colors to be printed upon the same.

The invention consists in a machine for printing wall-paper and the like, constructed with a printing-table, a color-box and a support for a printing-block, means of shifting the printing-block support from the color-box to the printing-table and back again, and pressing the block upon the color'box, and upon the paper on the printing-table.

The invention also consists in the construction andcombination of parts and details as will be set forth hereinafter and finally point ed out in the claims.

In the accompanying drawings, Figure 1 is a front-elevation of my improved machine for printing wallpaper. Fig. 2 is a rear elevation of the same. Fig. 3 is an end elevation, Fig. 4 is a vertical transverse sectional view taken through the center of the presser-bar when the printing-block is over the color-box. Fig. 5 is a horizontal sectional view, on the line 5 f Fig. 1. Fig.6 is an end elevation of the machine. Fig. 7 is an enlarged detail elevation from the rear of the mechanism for pressing out the block, and Figs. 8 and 9 are vertical sectional views, on the line 8 8, Fig. 7, the parts being shown in diiferent positions.

Similar letters of reference indicate corresponding parts.

The entire mechanism is mountedon a frame A composed of the two standards A legs, so as to bring them to the proper eleva tions. The printing table is provided with a suitable bed 13 0f felt orother yielding ma terial and is provided on its top at the side edges with two longitudinally-arranged anglebars B'above which the angle-bars B are arrangedand are pressed upward by suitable helical springs surrounding guide-pins for guiding said angle-bars B The printing block E is provided on its side edges with angle-bars E pressed down Ward by springs, which angle-bars E, when the printing block descends, can press on the tops of the angle-bars B and press thelatter downward, so that the bottom edges of saidangle-bars B press upon and hold the sheet of paper a passing over the bed of the printingtable.

The paper a. is'wound on a suitable roll B supported in brackets B of the printing table, over which roll B a weighted tension strap B rests which strap is attached to a cross-bar B of the bracket 13. The paper passes from the roll B under the guide-rollers b b, then over the printing table and over the feed-roller F, above which the two feed-disks F are arranged, that are mounted on the shaft F parallel with and above the roller F, said feed-disks F having soft rubher-rims F that rest on the paper passing over the feed-roller F. On the shaft f of the roller F a cog-wheel f is fixed and engages the cog-wheel f on the shaft F A cogwheel F mounted loosely on the shaft fof the roller F carries a spring-pawl F that engages a ratchet-wheel F fixed on the shaft f. A vertically guided rack F engages said cogwheel F and said rack is connected by a connecting-rod F with a wrist-pin'projecting laterally from a wheel F fixed on the end of the driving shaftB. Whenever the rack F? is moved upward, the shaft f is rotated by the action of the pawl F on the ratchetwheel F but when the rack F moves downward the ratchet-wheel F is turned in inverse direction on the shaft f without rotating said shaft, whereby a positive intermittent feed is obtained and the paper is only fed during the time that the rack F moves upward.

A slush-box G is supported sidewise of the printing table 0 on suitable standards, a frame Gr being arranged in the same, the sides of which are rabbeted so as to fit and rest on corresponding rabbets at the interior ofthe slush-box. The slush-box is filled with paper pulp and water in the usual manner to form a cushion or yielding color surface. An endless color-apron G passes over suitable rollers g on the slush-box and frame G and over rollers 9 in said frame and over a roller G mounted in the trough G at one end of the slush-box frame or table, which trough contains liquid color into which the roller G dips. A doctor G6 is attached to the trough G and adapted to bear against the endless apron G, so as to scrape off the surplus color which slush-box with a color-apron, doctor and other connected parts will be designated hereinafter by the term color-box.

The small shaft g over which the endless color-apron G passes, carries at one end a loose cog-wheel 9 which carries a pawl 9 that engages the ratchet-wheel g fixed on said shaft g. A rack 71. engages the cog-wheel g and the upper end of said rack being pivotally connected by a connecting-rod It, with the beveled cog wheel P driven from the main driving-shaft by means of the bevel cog-wheel P The racks h and F are so arranged and mounted that one passes upward While the other passes downward, or, in other Words, in such a manner that when the paper is fed the endless color-apron remains stationary, and vice versa. When the endless color-apron is moved, the paper remains stationary.

The printing block E is secured to a yoke E provided with an upwardly-projecting screw F. that passes through a nut E mounted to turn in a suitable slot of the vertically reciprocating presser-bar H. The presser-barH is mounted and guided to move vertically on a frame J having dove-tailed lugs that embrace the dove-tailed edges of a cross-bar J uniting the standards A of the frame, which bar J is provided with the longitudinalslot J A helical spring K has one end attached to the lower part of the presserbar H and the upper end is fastened to a pin K, on the slide J, which spring has a tendency to draw the presser-bar upward until a lug H of said presser-bar strikes against the bottom of the slide J, as shown in Fig. 8. The presser-bar is provided in its upper end with a laterally projecting lug H for a purpose that will be set forth hereinafter. Above said lug the presser-bar is provided with a vertical slot H, into which the pin H passes from the slide piece H mounted in a suitable recess of the presser-bar between one side of the presser-bar and the inner surface of the slide J which slot and pin serve to guide the presser-bar; A pin L projects from said sliding-piece H through the slot J of the slide J and the slot J of the bar J into a disk M pivoted on the slide J, by the pin M projecting from the slide J to the rim of which disk is fastened one end of ahelical spring M', the other end of which is attached to the top of the slide J, which spring M has a tendency to turn the said disk in the direction of the arrow 00 in Fig. 2, that is, to turn the pin L toward the top of the slot J The slot J is provided in the slide J to permit the up and down movement of the pin L. A wrist-pin N projects from the disk M into a guide-block N passing through the longitudinal slot 0 of a connecting-bar O, the opposite end of which is pivotally connected at P with a crank P on one end of a shaft P, by means of a rod P held adjustably in the end of the bar 0, which shaft P carries at the opposite end a bevel cog-wheel P that engages a bevel cog-wheel P on the main driving-shaft B.

A helical spring 0 is interposed between the sliding bearing block N in the slot 0 and the end of said slot, as shown in Fig. 2, which normally holds the block N at the left-hand end of the slide 0, but permits it to slide to the right when the parts are in the position shown in Fig. 7, without acting on the disk M. On the shaft B a cam-wheel R is fixed, which is provided with the two offsets R, B

A plunger S having dove-tailed edges is guided vertically by dove-tailed clips S on the top cross-bar of the frame and is pressed downward by a spring S having one end at tached to the plunger S and the other end to the frame of the machine. At its lower end said plunger carries at one edge an anti-friction roller T that can run on the rim of the cam-disk for a purpose that will be set forth hereinafter.

The operation is as follows: After the printing block E has been provided with color and brought into the position shown in Fig. 2, that is, above the paper on the printing table, the connecting-rod O continues to move in the direction of the arrow w, and as the sliding block N in which the pin N is held is now at the end of the slot 0, said pin N is also moved in the direction of the arrow w. This produces a turning movement in the disk M, whereby the spring M is brought in tension and the pin L moved downward. As said pin L is held in the sliding-piece 1-1 the said sliding-piece is moved downward and bearing on the bottom of the recess in the presser-bar H presses the same downward.

IIO

Thereby the printing block E is pressed upon I the paper resting on the printing table, which paper is now in a position of rest. Before the printing block comes in contact with the surface of the paper the angle-irons B are pressed down and securely hold the paper and the angle-irons E are pressed upward slightly so that as soon as the printing block E begins to rise the angle-irons 13 will not rise with it, but will remain in lowered position until the face of the block has been moved a short distance from the paper that has been printed, thus preventing this paper from being raised by suction. It is evident that the springs acting on the angle-irons 13 must be less powerful than the springs acting on the angle-iron E. As soon as the pressure is taken off the pin L, the spring K draws the presser-bar H upward into the position shown in Fig. 7, so as to fully clearthe devices on the printing table. The connecting rod 0 now moves in the inverse direction of the arrow to, Fig. 2, and moves the entire slide J and the disk M, the presser-bar H and the printing-block E in the inverse direction of the arrow to, that is, to the opposite end of the slot J By the time that the slide J has arrived at the left-hand end of the slot J Fig. 2, it is over the color-bath in the slush-box, and by this time the camroller R has moved to such an extent that the lower end of the plunger S slides oh the rim of the same and strikes against the lug H of the presser-bar H which by this time has been brought in line with the plunger and forces the same downward suddenly under the action of the spring K. The cam-wheel R again forces the plunger upward, when the camwheel R is further rotated. The plunger S, again descends under the action of its spring and again strikes the lug or shoulder H of the presser-bar, again pressing down said presser-bar which is then immediately raised by its spring K. During the rest of the revolution of the cam-wheel, the plunger S is held in raised position by the action of the rim of the cam-wheel on the anti-friction roller T on the lower end of the plunger S. As the printing block has twice been brought in contact with'the endless color-apron G it is uniformly supplied with color. While the printing block is in raised position, theslide J is moved by the crank-arm P and connecting-rod O in the direction shown by the arrow w Fig. 2, and again brought in position overthe printing table, where said printing block is again lowered and pressed upon the paper by the action of the end of the slot 0 on the pin N, whereby the disk M is turned in the inverse direction of the arrow as, Fig. 2, and the pin L is moved downward so as to depress the presser-bar and press the block upon the paper, and soon. During the time that the printing block is above the printing table, thepaper is at rest, but the rack 72. is being moved upward and turns the shaft g whereby the endless color-apron G is shifted in the slush-box, so that a fresh surface will be presented to the printing block when the same is forced down again by the plunger S. During the time that the plunger is above the color apron and is receiving color, the paper is shifted as at that time the rack F is moved upward and rotates the feed-rollers of; the paper in such a manner as to draw the requisite length of paper from the roll 13 over the printing table. As the feed of the paper is absolute and correct and precisely the'same length, the paper is fed each time the feed apparatus operates, The end of the figure produced by one impression of the printing block will tally exactly with the end of the next. After one color has been printed in this manner and the paper dried the paper can be run through the same machine with a different block, or the paper can be dried after leaving one machine and then immediately passed through a second machine having a block for printing a different color, and so on.

My improved machine can also be used for printing oil-cloths, carpets, window-shades and other fabrics, in which case, in place of a paper web, the web of a suitable fabric is fed over the printing table, and subjected to the action of the printing block as described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
