HENRY M. HARLEY, OF GLOUCESTER CITY, NEW JERSEY, ASSIGNOR OF ONE-HALF TO GEORGE A. HEYL, OF PHILADELPHIA, PENNSYLVANIA.

, FABRIC PRlNTING MACHINE.

SPECIFICATION forming-part of Letters Patent No. 641,104, dated January 9, 1900.

Application filed June 21,1898.

To all whom it may concern: V

Be it known that LHENRY M.HARLEY, a citizen of the UnitedStates, residing at Gloucester City, in the county of Camden, State of New Jersey, have invented a new and useful Improvementin Calico or Fabric PrintingMachines, which improvement is fully set forth in the following specification and accompanying drawings. I

My invention consists of a calico or fabric printing machine adapted to print each side of the fabric, the same employing a set of printing and impression rolls for printing one side of the fabric, a bridge over which said fabric is passed and by which it is reversed, and another set of printing and impression rolls for printing the other side of the fabric, the sets of rolls being at opposite ends of said bridge, thus producing an accurate register in the print of the two sides or faces of the fabric without the employment of a large main cylinder and the engagement of printing-rolls therewith as heretofore practiced in such machines.

It also consists in adapting said bridge to adjust the tension of the fabric passing over the same and to produce the best results in causing the register of the print or pattern of the two faces of the fabric.

Figure 1 represents a side elevation of a calico or fabric printing machine embodying my invention. Fig. 2 represents a vertical section of a detached portion thereof on an enlarged scale. Fig. 3 represents an end elevation of the machine. Fig. 4.- represents a diagramic view thereof. Fig. 5 represents a side elevation of a portion of another form of my invention. Fig. 6 represents a top or plan View thereof. Fig. 7 represents an end View thereof on an enlarged scale.

Similar letters of reference indicate corresponding parts in the figures. I

Referring to the drawings, A designates the frame of the machine, B the housings for the printing-roll C and impression-r011 D at one end of said frame, and E the housings for the printing-roll F and impression-roll G at the other end of said frame. The shafts of the rolls are mounted in adjustable boxes for evident purposes.

Adjacent to the roll 0 is the color-feed roll Serial No. 684,039. (No model.)

H, and adjacent to the roll F is t-he color-feed. roll J.

K designates the color-trough for the roll H, and L designates the color'trough for the roll J, said troughs being adj ustably mounted 011 the frame A by means of screws M or other suitable appliances.

The rolls of each set are properly geared together, and the two sets receive motion from the gear-wheels N, to either of which power is communicated.

P designates a bridge which has a slatted face and is preferably of the form of the segment of a circle and extends approximately from one set of rolls to the other, it being connected at one end with the housing B by means of the pivotal bolts Q and supported at its other end by the uprights P, the latter being adj ustably secured at their lower ends to the framework of th emachine. The means for adjusting said bridge comprise slots P in the lower ends of the uprights P, that receive bolts P on the frame of the machine, said uprights being held in place by nuts upon said bolts in a familiar manner. In this way the bridge can be raised or lowered to vary the tension upon the web passing thereover. To further vary and regulate the tension upon the web between the sets of printing and impression rollers, the delivery end of the bridge is provided with a roller W, mounted in boxes S, that are movable in upright guides S in the sides of the bridge. The blanket passes over the bridge and around the roller W and around the impression -roller D of the first set of printing and "impression rollers. The boxes are engaged by the screw-threaded portion of a rotatable adjusting-rod R, supported by a bracket T and geared, as at u, with a crank-handle V. By turning said handle V the roller W is raised or lowered through the intermediacy of the gearing described,as may be required to regulate the tension upon the web between the two sets of printing and impression rollers. The bracket T is of course suitably mounted to suit the adjustment of the bridge. The web passes from the imlivery from the impression-roll D and the feed to the impression-roll G, whereby the web is caused to rest upon said bridge at all times during its passage between the rolls, the curvature of the bridge affording an approved bed therefor and with which the web is in close contact th roughout its entire length. The curvature of the bridge and the fact that the web approaches and leaves the same from the convex side thereof gives the web an extended and even contact therewith from end to end, so as to preserve the best alinement between the two sets of printing and impression rollers. The web moving in contact with said bridge between the sets of printing and impression rollers and the roller V at the delivery end of said bridge being adjustable to vary the tension upon said web it is obvious that it is held against deviation from a direct course between said sets of rolls and maintained in the desired alinement to secure the best results in causing the patterns on opposite faces of the web to register.

I employ additional printing-rollers X X when desired and provide the same with colorsupplying rollers Y Y and color-troughs therefor, with means for adjusting the same, as will be most plainly seen in Figs. 1 and 2.

As usual in fabric-printing machines, I may employ the backing-sheets Z Z, which are guided on the rollers Z Z and in the present case passed around the blanket on the bridge and rollers D and \V and that on the roller G. One backing-sheet Z leads from its roll first to and around the impression-roll D, and thence across the bridge P, being situated adjacent to the blanket passing around said ports. After passing around the bridge the backing-sheet is again passed around the roll D and bridge P, this second lead being situated upon the first lead, while the paper passes over this second lead. The other backing-sheet leads from its roll first around the.

impression-roll G and upon the blanket thereon and is then again passed around said roll G and upon the first lead, while the paper passes over this second lead.

The operation is as follows: Power is imparted to the machine and the fabric passed between the rollers G and D, whereby it receives an impression, and may then pass between the rollers X and' D, where it recives another impression, both being on the same face. Then it traverses the bridge P and passes under the roller G, so that it may be said to be reversed, whereby it is subjected to the printing-roller F on the face opposite to that first printed, and may also receive another impression from the roller X on said opposite face, and thus both faces of the fabric are printed, the parts of the machine being adjusted and timed so that there is an accurate register of printing 011 the obverse and reverse faces of the fabric. The fabric after being printedis carried from the machine and directed to a drying apparatus for evident purposes.

When it is desired to impart motion' to the slats or face of the bridge, (see Figs. 5, 6, and 7,) said slats are connected with sprocketchains forming an endless apron or blanket A, said chains being engaged by sprocketwheels B on the ends of said bridge, the shaft of said wheels being geared with that of the adjacent impression roll 0, whereby the apron receives positive motion and so assists in carrying the fabric over the same.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-
