Application October 9, 1933, Serial No. 692,808 Renewed November 7, 1936 6 Claims. (01. 101 178) vide an improved machine of this character in which means are provided to print simultaneously at least one pattern on each of two or more 10 separate fabrics or similar materials.

On conventionally constructed machines for the printing of textile fabrics, it is possible to print, depending upon the capacity of the machine, from one to sixteen color-combinations or 15 patterns on one fabric, but on one fabric only, while by this invention, a plurality of separate fabrics may be printed simultaneously with one or more separate patterns or color combinations for each fabric.

Other objects and advantages of the invention will appear as the description proceeds.

The drawings accompanying this specification are of a machine embodying the features of the present invention and in which Fig. 1 is a side elevation of printing machine with our invention attached taken from the drivingside and Fig. 2 is a side elevation of a printing machine with our invention attached taken from the opposite sidethereof.

" Referring to the drawings, we designate the frame of the textile printing machine in which is mounted on its horizontal shaft, the freely rotating pressure cylinder 2 of comparatively large diameter, in contact with the surface of which the usual blanket 3 if employed travels during its passage around a portion of the surface of the cylinder. The driving gear 9 imparts motion to the driven crown wheel or spur gear 4 which is mounted for rotation on a stud shaft secured in the frame of the machine. The idle spur gear 5 is mounted, on roller bearings or similar de vices to insure easy rotation, in thesame manner and relative position as spur gear 4, but preferably on the opposite side of the machine. Spur gear 5 may be of the same size and may have the same number of teeth as spur gear 4. By I I, l2, l3, I4, l5 and it are designated the nips on both sides of the machine holding or containing: the head stocks or center boxes, the nip pressure 0 screws, the adjusting and back-out screws for the mandrel boxes, the color pan hangers, the

doctor steps and boxes, and finally, the bearings,

holding the mandrels which serve as temporary axles for the printing rollers when the latter are 55 placed in the printing machine. Each roller works thus in combined spring and lever adjustable bearings which allow of its being moved whilst the machine is in motion. The fitting gears, which may be of the same type and size, are here classified according to the side of the machine on which they are used. The fitting gears 6 are set in the usual manner on the gear side of the machine on mandrels with bearings of the conventional type. The fitting .gears l are set on the opposite side of the machine on mandrels running in roller bearings or similar devices, to insure easy rotation. The drag roller 8 serves to feed or guide the fabrics and greys into the machine and onto the cylinder.

As is the usual practice in the operation of machines of this type, motion is imparted to the printing rollers on their mandrels by means of fitting gears 6, said fitting gears being adapted to be meshed for perfect adjustment or fit with spur gear 4, motion being imparted to the latter by a driving pinion from any suitable source of power. The mandrels with printing rollers and fitting gears I and their bearings are adapted to be meshed for adjustment or fit with idle spur gear 5., Said fitting gears l and the cylinder 2, neither of which are directly coupled to the drive-of the machine, are rotated by the fric-' tion caused by said cylinders pressure upon the revolving printing rollers set on mandrels carrying the fitting gears 6.

It is believed that the operation of the machine will be understood from the foregoing descriptiontaken in connection with the drawings, but for purposes of illustration, the process of printingon our machine simultaneously, for in stance," two separate fabrics with a two-color or two+roller combination on each, is cited below:

The ni'ps holding the mandrels of the printing rollers are numbered in this illustration from H to 16,]! being in rear, It being in front of the machine, and both approximately on the same level as the shaft of the cylinder. 'The space between II and I6 is taken up by nips l2, l3, l4 and I5 around the lower portion of the cylinder, where they are placed about equidistant from each other.

For the printing of two fabrics with a twocolor combination on each, two printing rollers and a gum roller on mandrels provided with suitable fitting gears as shown at 6 are set in nips l4, l5 and (gum roller) 16 on the gear or machine side in the conventional manner andare meshed for fit with spur gear 4. Thereafter, two printing rollers and a gum roller on mandrels wit. suitable fitting gears as shown at"! are set on the opposite side of the machine in nips ll, l2 and (gum roller) l3 and are meshed for fit" with the idle spur gear 5. After color pans and doctors, etc. have been inserted, the machine is ready to receive the fabrics to be printed.

There is fed into the machine so prepared, over the drag roller 8 in the usual manner, a fabric or goods and a back grey, these two being hereafter referred to as layer I'I, passing along with the blanket 3 on the surface of the lower portion of the cylinder 2 until it comes to printing roller in nip I4 and subsequently l5, and after passing gum roller I6, saidlayer l1 leaves the machine in the well-known manner. A second layer, hereafter called layer l8, consisting of a waterproofed grey, an ordinary back grey as used in layer l1 and a second fabric, is fed into the machine simultaneously with layer 11 over the drag roller 8.

Layer I8 is carried along with the blanket 3 and with layer l1, on a portion of the surface of the cylinder until it comes to nips I l and subsequently l2 with their printing rollers provided with the fitting gears 1, and after passing gum roller at l3, it leaves the surface of the cylinder and travels downward.

When the driving gear 9 is set in motion, it turns the spur gear 4, thereby causing the printing rollers provided with fitting gears 6 in nips l4, l5 and It to rotate in synchronism, said printing rollers imparting frictional motion to cylinder 2, and the latter causes the printing rollers provided with the fitting gears 1 in nips II, I! and I; to revolve in synchronism. An imprint is made on the fabric of layer I! by the printing rollers in nips l4 and I5, and on the fabric of layer I8 by the printing rollers in nips II and I2. g

The printed fabric and the back grey of layer I! are taken care of in the usual, well-lmown manner, the printed fabric being separated from the back gray and blanket and guided away from said cylinder for further treatment by the guide roller l9.

The disposition of layer l8 presents a novel feature of our improved printing machine.

As indicated above, layer I8 leaves the cylinder after having passed gum roller at I3 and travels downward. Under the floor of the machine, suitable dry-cans and drying chambers are installed and through an opening in the floor, the fabric, waterproofed grey and ordinary back-grey of layer l8 are led, are suitably separated and the fabric layer is suitably guided by suitable means such as the guide roller 20'onto them.

A waterproofed grey is used in layer l8, in order to prevent the color printed on the fabric of said layer from penetrating to the fabric of layer II.

It will be readily understood by persons versed in the art that this improved printing machine ofiers a greatly enlarged capacity compared with that of the old, conventionally constructed machine. Whereas the example of a six-color machine has been cited, larger and smaller machines constructed under this invention lend themselves to the simultaneous printing of a plurality of fabrics or similar materials. By installing, for instance, an additional idle spur gear on the opposite or driving side of the machine and by using longer mandrels than are conventionally used today, it is possible to set additional fitting gears, thus allowing an additional multi-color or multi-roller pattern or combination to be printed. Another factor to be taken into consideration a suitable gum printing roll if employed with one or more printing rolls depending on whether single or multi-colored patterns are desired to be printed. Having thus described our invention, we claim:
