JAMES FARMER, OF SALFORD, ENGLAND.

MACHINE FOR PRINTING OR EMBOSSING FABRICS.

SPECIFICATION forming part of Letters Patent No. 477,205, dated June 21, 1892.

Application filed September 16, 1889. Serial No. 324,166. (Modeh) Patented in England January 12, 1889, No. 603.

To all whom it may concern:

Be it known that 1, Sir JAMEs FARMER, a subject of the Queen of Great Britain, residing at Salford, in the county of Lancaster, England, have invented certain new and useful Improvements in Machinery for Printing or Embossing certain Fabrics and Materials, (for which I have obtained Letters Patent in Great Britain bearing date January 12, 1889, N0. 603,) of which the following is a specification.

My presentinvention consists in certain improvements on the invention for which I obtained Letters Patent in the United States, No. 408,913, dated August 13, 1889, and in Great Britain, numbered 10,431, dated July 27, 1887, and entitled improvements in and machinery for printing floor-cloths and textile and other fabrics and materials and also for embossing certain materials or fabrics.

The objects of my present improvements are to improve the mechanism for actuating the printing-blocks and the arrangement for inking the same. I attain these objects by the mechanism illustrated by the accompanying sheets of drawings, in which- Figures 1 andl represent a side elevation, Figs. 2 and 2 a plan, and Fig. 3 an end elevation, of a two-eolor printing-machine-that is, a printing machine provided with two separate color-boxes and printing-blocks, each box having a different color-to which my improvements have been applied. Fig. 4 shows the inking-roller appliance. Fig. 5 is a longitudinal section of a two-color machine, all unnecessary parts omitted. Figs. 6 and 7 show the printing-b1ocks (Z at different times in the forward stroke, as indicated by the arrows. Fig. 8 shows the blocks (6 on their return stroke when they are supported and travel back upon the lever g above the inclined rails e and clear of the inking-roller. Figs. 9 and 10 represent side and end views of one of the printing-blocks (Z. Figs. 11 and 12 represent the inking-rollerj and the colorbox t', with the screws by which it can be adj usted vertically.

Referring to the drawings, a designates the main frame of the machine.

I) I) are two frames mounted in slideways a (see Fig. 3) on the frame a and coupled together adj ustably by screwed co nnecting-rods c and nuts 0' or equivalent connections, so that the distance apart of the two frames I) can be regulated as required. To these combined framesb a sliding reciprocating movement to and fro on the main frame a is imparted by the mechanism shown and heroinafter described or by any other suitable and convenientarrangement. Each of the sliding frames Z1 has a standard I)", in whichis a slideway titted with a slide-block b and each pair of slide-blocks b on opposite sides of the machine earry one of the printing-blocksd. On a shaft extending across the machine or on a trunnion b secured to or formed with each sliding block is mounted an anti-friction roller b, which runs on a guide-rail c, fixed 0n the main frame a. These guide-rails e for a certain length beyond each block cl lie in a horizontal plane and then dip down and rise again in a curve to a horizontal plane, as shown best in Fig. 1. Below the bottom of each dip or curve in the guide-rails e is placed a sliding table f, to which a reciprocating motion is imparted at a certain time as and by the means hereinafter described. To a bracket a on the framing and above the center of each dip in the guide-rails e are pivoted an elbow-lever g on the side nearest the first block (Z and a short lever 71. on the other side. The long arm of each lever g is kept normally raised, as shown in Fig. 1, by means of a weight g or by a spring, while each short lever h is kept by its own weight normally lowered in a horizontal or approximately-horizontal plane. Between each printingblock d and dip in the guide-rail is placed a color-box 'L', which is vertically adjustable by means of screws 1', and in each color-box is mounted a color-rollerj and a doctor-roller 7r. On each color-roll'erj is fixed a pinion j, gearing into a pinion It on the doctor-roller 7e and on each forward stroke of the sliding frames 1), while the rollers l) are running on the guide-rails c, racks (Z, fixed on the under side of the printing-blocks (Z, gear into the pinions j, and so drive both the colorrollers j and doctor-rollers 7.;. On the return stroke of the sliding frames 1), while the rollers Z)" are running on the upper side of the elbow-levers g, as subsequently explained, the racks (1 pass over without drivingthe pinionsj, so that the color-rollersj and doctor-rollers 7; remain stationary until the next forward stroke of the sliding frames 1).

The mechanism for imparting a reciprocating movement to the sliding frames Z) in the arrangement shown consists of the following parts: The driving-shaftl carries a pinion Z, which gears into and drives a spur-wheel m, fixed on a shaft 171, on which is also fixed a :0 disk m with an eccentric-pin m connected by a link a to one of two rocking levers 0, which are fulcrumed and fixed on a rocking a shaft 0', supported in bearings a in standards I The upper ends of the rocking levers 0 are connected by links 0 to the of the frame a.

sliding frames 1), so that as the disk m revolves and the eccentric-pin m thereon by the link n rocks the levers 0 a reciprocating motion is imparted by the links 0 to the slid 2 5 ward the pairs of stops b I) come in contact with and carry forward for a certain distance the sliding tables f, while on the return stroke the sliding tables f are moved backward by the pairs of stops 1) b 0 The floor cloth or fabric 1) to be printed is batched upon a roller 19, supported in stand ards p and the fabric is traversed through to insure good printing, preferably by means 3 5 of a traveling chain r on either side of the These chains r, which have needle-points, extend from end to end of the maj chine, and aremounted upon chain-wheels 0*,

machine.

which are supported on the framing a. The

a guide or roller 19 which extends across the width of the machine, and is pressed onto the needle-points of the chains 9' at each edge by means of brushes 5, which are fixed one above each of the first pair of chain-wheels r. The

'second pair of chain-wheels *r are fixed upon a shaft r upon which is also fixed a bevelgear r which is driven by a bevel-gear t, fixed upon a shaft 2?. On the other end of this shaft 25 is'fixed a bevel-gear 15 which is driven by a bevel-gear u on a shaft to, on which is also fixed adj ustably an elliptical gear M, which is driven by another elliptical gear '0, fixed on a shaft r.

spur-wheel m fixed on the shaft m, which receives motion from the driving-shaft a, as before described. As the chains 1" and chainwheels 7' are driven from the shaft m, which can insure the fabric 19 traveling at the exact speed required at the moment of printing.

The operation of the machine is as follows:

The shafts-also has fixed 55 upon it a spur-Wheel 19, which is driven by a J As the rocking levers 0 oscillate and the combined sliding frames 1) I) begin to move forward, each printing-block cl passes over and is inked by its color-rollerj, which is caused to rotate while the printing-block passes over it by means of the rack (1 and gears, as described. After the printing-blocks (1 leave their respective color-rollersj they pass under the raised long arms of the pivoted elbowlevers g, and leaving the horizontal portions of the guide-rails cthey descend the curves and print the fabric 1) upon the sliding tables f, which at that moment are caused to move forward with the sliding frames 1) by means of the pairs of stops b b, as before described. The fabric also being drawn forward by the chains 7'', which at the moment of printing are driven at exactly the same speed as that at which the printing-blocks d are mo-ving,it follows that the printing-blocks (Z, the fabric p, and the sliding tables f all travel forward together at exactly the same speed. Immediately thefabric has been printed the printing-blocks d begin to leave the sliding tables f as they ascend the opposite sides of the curves in the rails c, and then rising and passing under the second pairs of pivoted levers 71. they again arrive on horizontal portions of the guide-rails e, but

.; on the opposite side of the curves from that on which they started, the letters It falling down again after the rollers bi have passed.

The rocking leverso now begin to move in the the machine at the varying speeds necessary reverse direction, and as the sliding frames 1), with the printing-blocks 61, return the rollers b run on the upper side of the pairs of pivoted levers h and g, the levers gbeing pressed down into the required position by the rollers 19 passing over them. During the greater portion of the return movement of the sliding o fabric 1) passes from the batch-roller 1) over frames 1) the sliding tables f remain stationary; but a little before the rollers 19 leave the levers g and come again onto the surface of the guide-rails e the stops 6 b catch the tables f and push them back to their initial positions, ready for the next printing stroke.

Although for convenience of description I have specified my invention as applied to a two-color printing-machine,itis obvious that my improvements are equally applicable to a single-color printing or embossing machine and also to machines with three or more printing-blocks. I

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim, and desire to secure by Letters Patent of the United States, 1s
