METHOD AND MACHINE FOR PRINTING FABRICS.

Application tiled October 25, 1923.

This invention relates to fabric printing machines of the type disclosed in our Patent N o. 1,480,348, dated Jan. 8, 1924, which machines produce a raised or bas-relief ornamentation upon the fabric by means of a perforated stencil, through which a print-v ing composition of a thick pasty consistency is fed to the fabric.

ln the machines of this type as heretofore constructed by others. it has been possible to produce only single colored ornamentations, by one running of the fabric through the machine and while multi-colored effects and designs employing the bas-relief stencil ornamentation as a part thereof have been heretofore produced, they have only been produced by hand labor and consequently have not been extensively used because of the resultant high costs of production.

' The principal object of this invention is to provvide a new and improved construction of a machine capable of performing in a. single running of the fabric through the machine, a printing of a bas-relief ornamentation with one or more perforated stencils in connection with or supplementary to a printing of a fiat ornamentation with the one or more of the usual solid printing rolls.

Another object is to so construct the machine that the line contacts against the pressure roller of the several printing devices employed, may be adjusted so as to secure an accurate registration of the component parts of the finished design.

For the accomplishment of these and such further objects as will be apparent to those skilled in the art to which this appertains, the invention consists in the construction, combination and arrangement of parts an embodiment of which is hereinafter more,

Serial No. 670,670.

tail of the means for adjusting a solid printing roll. i

5 is a sectional view therethrou h.

Fig. 6 is a diagrammatic illustration 0% a sample of the work printed in the machine.

As shown in the drawings, the numeral 10 indicates generally the frame of the machine on the front side of which is mounted the feed roller 11, containing the fabric to be printed, which is led therefrom about an idler roll 12, and thence about a large pressure roller 13 against which the solid printing roller 14 and stencil 15 engage.

The pressure roller 13 is rotatably mounted in bearings 16 slidably mounted in suitable guides in the frame 10 and screws 17 are provided for the vertical adjustment of the bearings and roller to regulate the print- 111g pressure. Any suitable driving means such as the pulley 18 and belt 19 leading to a convenient source of power may be employed for driving the roller 13.

The solid printing roll 14 is keyed, as at 20, to the shaft 21 and is provided at one end with a driving flange 22 apertured to receive the bolts 23 which pass through the arc shaped slots 24 provided in a driving gear 25 which meshes with a large gear 26 secured to the pressure roller 13. Means are provided for adjusting the pressure of the printing roller 14 against the pressure roller `13 and for this purpose the shaft 21 is mounted in the bearings 50 which are slidably mounted in suitable guideways 51 formed in the frame 10. The ressure screws 52 engage with the upper aces of said bearings to force the printing roller into printing contactwith the fabric and the compression springs 53 are provided for moving the roller 14 away from the pressure roller 13 when the screws 52 are released.

The construction of the stencil 15, the mounting thereof, and the means for feeding the printing paste or composition therethrough, is similar to that shown in the 100 above mentioned patent and a brief description thereof will suiiice for the purposes of this application.

The stencil 15 is mounted for free floating rotation upon a non-rotatable supportvpreferably in the form of a hollow drum 27 which has its outer ends clamped between aclamping device, the lower half 28 of which is formed in a bracket 29, suitably secured to the frame 10, and the upper half 30 of which 110 is detachably secured to the lower half by means of the bolts 31. A portion of the lower part of the drum 27 is cutout, as at 37, to permit a combined pressure element and distributing blade 33 to contact with the inner circumference of the stencil and hold it against the pressure roller 13. The pressure element 33 is provided with trunnions 34 removably mounted in the split bearings 35 formed in brackets 36 adjustably bolted to the sides of brackets 29. and to the projecting ends of said trunnions, are secured the lever arms 37, upon which the weights 38 are adjustably mounted for holding the pressure element 33 with ay lyielding constant pressure against the pressure roller 13.

A pipe 39. which is connected with a suit.- able reservoir, (not shown) containing a supply of printing composition for the stencil 15. extends into the drum 27 and is pro- Avided'with a plurality of nozzles 40, which deliver the printing composition to a trough 41. mounted within the drum 27 and extending the full length thereof. The trough 41 is provided with a foraminated bottom through which the printing composition flows to a deflector plate 42, the lower edge of which terminates adjacent the lower edge of the pressure element 33.

Printing composition is supplied to the roller 14 by any suitable means such as the iuking roller 43 mounted in the lower end of ink fountain 44.

ln the operation of the machine` the fabric passes from the feed roll 11 around the idler roll l2 and between the printing roller 14 and pressure roller 13. The printing roll 14 is provided with any suitable design as for example the leaves 46 (Figs. 2 and 6) which are cut into the roller or which may be formed in an electrotype detachably secured to said printing roll in accordance with the well known constructions of devices of this character. After the design on roller 14 has been printed, the fabric passes between the stencil 15 and the pressure roller 13 to receive a second printing of the characteristic bas-relief ornamentation produced by this type of printing. In the design shown in Fig. 6 the leaves 46 are outlined or surrounded by a plurality of raised dots 47. At the beginning of the printing operation. the printing roll 14 and stencil 15 are set to insure proper registration vof the ornamentations with one another` which may be done by raising levers 37 to release the. pressure of pressure element 33 on the stencil and then shifting the stencil about drum 27 or the settingof the pressure roller 14 may be. changed b v loosening the bolts 23 and shifting the flange 22 and roller 14, relatively to the gear 25 or for larger adjustments withdrawing the roll 14 and gear 25 suiciently from the pressure roller to shift the gear tooth engagement o

gears

25 and 26. After the printing by the stencil 15. the fabric is preferably led directly from the machine to a drying machine.

It will be understood that the diameters of the stencils and printing rollers employed must be exact multiples of one another to cause the repetition of the designs or ornamentations to fall upon the fabrics .in exact superimposed relation or alignment and also that if any of the various printing stencils and rollers' contain only a single unit of a motif for the final design in a circumferential direction, the contact line of such printing member with the pressure roller 13, would have to be located at such a dist ance from the contact line of the succeeding printing member as to cause the successive printings to be brought into proper registration.

lhile for the purpose of this application we have only shown one stencil 15 and printing roll 14. it will be obvious that any number of such printing devices could be einployed in accordance with the number of colors which it is desired to reproduce in the finished product.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:
