To all 'whom t may concern.'

Be it known that I, PATRICK H. MCGIE- HAN, a citizen of the United States, residing at New York, in the county of New York and State of New York, haveY invented certainnew and useful Improvements in 'Machines for Printing Carpets, Floor-Rugs, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a machine for printing large carpet, floor rugs and the like.

Heretofore it has been the practice to print relatively narrow strips of carpet and similar textiles and sew the strips together to provide a rug of the required size, and this invention has for its object to provide a simple, practical and. efficient printing machine of comparatively inexpensive construction adapted to print the entire design of large rugs, such as nine by twelve feet and othersizes and to enable such material of the complete width of the finished rug to be continuously run through the machine and printed in various colors from the web, thereby obviating the necessity of printing such rugs in several separate and distinct operationsv and then -matching and sewing the strips or sections of the rug together and at the same time enabling rugs of greater artistic appearance to be produced in less time and at a much lower cost than heretofore. y

As the size and weight of the printing rollers of the machine are necessarily in-` creased to such an extent as to prevent ac' curate and effective operation in their usual positions below the main cylinder,vit is also an object of the present invention to enable the printing rollers and other parts to be made the required size and weight without affecting the alinement of the rollers and the proper positioning of the same with relation to the main cylinderor platen' by having the printing roller above the horizontal center of the main cylinder.

A further object of the invention isto provide driving means adapted to assist in supporting the weight of the main cylinder or platen and capable of adjustment to vary y the pressure and adapted also to produce a uniform rotation ofthe printing rollers and.

the main cylinder or platen so that accurate printing with the increased size of the cylinrificing any of the advantages of the invention.

responding parts in the several figures of the drawings.

In the accompanying drawings, in which is illustrated the preferredembodiment of' the invent-ion, the machine, which is designed for printing large rugs, carpet and the like, comprises in its construction a main cylinder or platen 1 mounted upon a horizontal transversely disposed shaft 2 which is journaled in suitable bearings 3 of a main frame having sides or side frames 4. The bearin s 3 are vertically adjustable and the main rame, which may be of any desired construction, is provided .at the upper portions ofthe side frames with radially projecting arms or nips 5 in which are mounted printing rollers 6 whichv are located at'the top of the frame in order that their welght may maintain `them in proper alinement with the main cylinder or platen. Byv this arrangement, the main cylinder `or platen and the printing rollers may be made of any required size and weight and there will be no liability of the printing rollers sagging or otherwise getting out of alinement with the main cylinder or platen through such excessive weight of the rollers, as is the case when heavy rolls are located below the main cylinder or platen in the position occupied by the' printing rollers of relatively small fabric printing machines like those in present use. The arms or nips are of substantially the ordinary construction and the printing rollers are supplied with colors from color boxes 7 by means of furnisher rolls 8 which are connected or meshed with the printing rollers by gears 9 and 9, one furnisher gear being fixed on theshaft of the furnisher roller, and the other furnisher gear 9a of the shaft of the printing roller.

The main cylinder or platen is arranged to have carrying or rotating support upon a pair of horizontally disposed rolls 10 having shafts 11 which are journaled in adjustable bearings 12. The bearings 12 or bearing boxes are vertically adjustable by means of vscrews 13 and they are mounted in suitable guides 14 of the sides of the main frame. By adjusting the rollers, the pressure may be increased or decreased and the said rollers will assist in supporting and rotating the main cylinder or platen and are located at opposite sides of the center of the bottom of the same. The shafts 11 of the adjustable horizontally disposed supporting and driving rollers are equipped at their left hand ends in Fig. 3 of the drawings with pinions 15 which mesh with a main cylinder gearl which is keyed or otherwise secured to the horizontal shaft 2 of the cylinder or platen 1 and the said shafts 11 are provided at the right hand ends in Fig. 3 of the drawings with pinions 1,7 which mesh with an intermediate gear wheel 18 mounted on a stud 19 and adjustable to accommodate larger or smaller intermediate gear which'is necessary when the diameter of the printing rollers are changed.4 This intermediate gear 18 meshes with fitting gears 20 of the printing rollers 6. This gearing of the ends of the horizontal supporting and driving rollers 1() with the main cylinder gear and the intermediate gear produces a positive and steady drive and Will eliminate any jerking and a uniform s peed will be transmitted to the cylinder and the printing 26a of a horizontally disposed worm shaft 27, which is mounted in suitable bearings 28. The worm shaft 27 also carries a pinion gear 29. constructed of rawhide or other suitable material at its engaging portion and meshed with or engaging a similar pinion 30 mounted on the shaft 31 of an electric motor 32, but any other suitable form of motor may of course be empio ed for operating the printing machine. he pinion and the worm gearing provide a simple and efiicient means for transmitting motion to the gearing which connects the heavy adjustable supporting rollers which assist the rotation of the main cylinder and assurev the same peripheral speed in the main cylinder and the printing rollers.

The fitting gears, which are arranged at the ends of the printing rollers at the right hand side of the machine, are mounted on the shafts or mandrels thereof in the usual manner so that the rollers can be turned in either direction for the purpose of fitting the pattern to be'printed on the goods or material, each printing roller printing a separate or different color in accordance with the design of the pattern. The engraving in each printing roller is different as each roller is to print a separate color to form a complete six color pattern or design.- The fitting gears are so constructed to enable the operator to turn any of the six rollers slightly one way or the other without rotating the intermediate gear or the toothed portion of thefitting gear so that the color of the design printed by each roller will fall in its relative'position with the other colors and will thereby form and print thev design in accordance with the pattern engraved on the printing rollers. VFor the sidewise motion or adjustment to fit the pattern sidewise there will be post-head screws 33 provided in the outer sides of the head blocks 34. The post-head screws engage the Vprinting roller sliding bearing or brass 34 so that by releasing the screw in one side of the machine and tightening 'up the screw in the block at the opposite side of the machine, the entire printing roller can be moved sidewise in either direction, thus fitting the pattern sidewise. The head blocks are adjusted by pressure screws 33a which'are for the purpose of applying additional pressure to the printing rollers for drawing back or lessening the pressure as may be required in getting a proper impression.

Around the main cylinderor platen is anV endless cotton or woolen blanket 35 which is also arranged on an adjustable tension roller 3G. The adjustable tension roller 36 is mounted in open bearing recesses 37 of adjustable bearings 38 slidably mounted upon a suitable support and guide 39 and moved backwardly and forwardly along the same in a direction longitudinally of the machine by means of adjusting screws 40 threaded through the said bearings 38 and mounted in suitable bearings 4l. The longitudinally disposed adjusting screws are connected by suitable gearing 43 with a transverse operating shaft 44 equipped with a hand wheel 45 or other suitable means for operating the adjusting screws to regulate the tension of the blanket. The blanket extends from the tension roller to an adjustable guide roller 46 located beneath the main cylinder and mounted in slidable bearings 47 which are adjustable by screws 48. The screws 48 are journaled, in suitable brackets 49 and are equippedat one end with a hand wheel 50 for adjusting the tension and guide roller. 'The blanket passes beneath the adjustable guide roller in a direction indicated by the arrow in moving toward the main cylinder, and when it leaves the'main cylinder at the back thereof it passes beneath a guide roller 51 mounted in fixed bearing brackets 52. The guide rollers 46 and 5l and the tensioning roller 36 form a tensioning loop in the endless blanket at the bottom of the main cylinder and the blanket is arranged at an inclination from the guide roller 46 to thel cylinder.

rll`he goods or material 53 to be printed is' arranged in the form of a roll or web 54 which is mounted on a shaft or spindle 55 and the latter is journaled in a suitable stand or frame 56 located at one end of the printing machine. rlhe material ypasses over horizontally' alined carrying rolls 57 and 58 to a guide roll 59 and it extends upwardly from thev bottom of the latter over guide rolls 6() and 6l to a rubber covered roll 62 hung in suitable brackets 63 and located at the bottom portion of the main cylinder and adapted to press the goods or material 53 against the blanket with sufficient force to enable the main cylinder or platen to feed the material to the machine by drawing the materia'l from the roll 54. The printing rollers, pressing against the main cylinder or platen, will draw the goods to themachine and the goods will be laid on the top of the blanket and carried by the rotation of the cylinder around the same between the said cylinder and the printing rollers to print the 4various colors at the points of contact with the said printing rollers. The printed goods, after leaving the last printing roller, passes downwardly over an arcuate series of carrying rolls 65 located above the carrying rolls 58 and enabling'the said printed material to be carried printed side up to a drier 66 having a large driven roll 67 at the front thereof as clearly shown in Fig. 4 of the drawings. This driven roller 67, soft rubber covered, will be driven, by a motor 67a or in any other suitable manner, to rotate at the same peripheral speed as the main cylinder or platen. When the goods have passed through the drier, having been printed and dried, they are then cut off at the proper points or center of margin between the printed designs and are hemmed, thus completingthe rugs in large sizes such as nine feet by twelve feet in a single operation.

The machine may be made of any desired size and any required number of colors may of course be provided and, owing to the particular arrangement of the arms or nips and the printing rollers above the horizontal artis or center of the main cylinder or plates, the very large and heavy printing rollers will be prevented from springing and will be caused to be maintained in perfect alinement by their weight. This arrangement with the adjustable supporting driving rollers and the means for rotating the same and the main cylinder or platen and the printing rollers will produce the same peripheral speed on the main cylinder and the said rollers and will cause a positive and steady drive without any erking of theparts, thus maintaining the fit of the pattern or design being printed.
