REVOLVING STENCIL-GYLINQER -MACHINIE 1.

Application filed January 1a, 1926. Serial m. 80,901.

This-invention relates to'improvements in cylinder printing machines for textile or paper plants, the invention having more particular reference that is intended to print several colors simultaneously. The invention has for an objectthe provision of an improved inking arrangement for machines of the class as here mentioned. For further comprehension of.the invention, and of the objects and advantages thereof, reference will be had to the-following description and accompanying drawings,

' and to the appended claims in which the Va.

rious novel features of the invention are more particularly set forth. I

My improved in ing arrangement is adapted to textile or paper printing machines, of the cylinder type forv printing several colors simultaneously, and I will therefore describe 1 f briefly a machine of this type.

The cloth, silk, linen, wall paper, or other similar material .10 to be printed is driven over the drum 11, by, means of rotating the drum by a belt extended over a pulley 13, at-

tached to a shaft and to the reduction gear-- ing 14, by means ofwhich the'mainshaft 15, the bevel gears 16, vertical -shaft 17 and bevel gears 18, drive the drum 11, the drum being rotatively supported in the frame 19,

to a novel type of machine.

FrICE.

vIcron nosn'ro, or BRONX, New Your as at 20, which also pivotally supports the shafts 21, by means of the brackets 21 which drive the printing cylinders 22, by means of shafts 23, andsuitable gears 24 and 25, the said printing cylinders 22 being pivoted as at 26, so as to vary th'epressure of the printing roll 22 against the'material 10 tobe printed, by means of a threaded shaft 27 having a hand wheel 28.

It will be understood that my improved inking arrangement is 3 adaptable to all classes and type of textile cylinder printing machines designed for printing several col-- ors simultaneously, and that I do not necessarily confine myself to the particular type or class of machine as here briefly described.

Referring in particular to my improved inking device, the printing'cylinders 10, are rotated as heretobefore described, andlcomprises a hollow cylinder 29 having. a plural-- ity of apertures .30, and a covering'31, of

felt or any suitable absorbing material. and a stencil 32, preferably of bolting cloth or silk, the two latter. named elements being firmly secured to, the hollow cylinder 29-by means of a clamping device comprising a clamping member 33, having an elongated aperture 34, to accommodate a wing nut 35 or any similar screw, threaded into the end of the hollow cylinder, it being understood that the said clamping devices arelocated at Z The tubular member 37 has an aperture 40,

suitably located at its lower periphery.- The ink container 41 is of hollowv semi-circular shape, and is attached to the tubular memr 1 her 37, as at 41', the heretobefore mentioned construction being such as will permit the ink which is poured. or otherwise placed in the filler 36 to enter theink container 41, throughthe tubular member 37 and the aperture 40. As this inkis to be used to cover tlie stencil 32, it is necessary that the amount or quantity of same be regulated, and for this purpose, I have provided a valve artached thereto, as at 47, and having set" s rews 59 located in slots on the tubular menil'ier 37, so as to allow movement of the hand wheel 46. which will slidably operate the said rod 45, .so that the wedges 48 attached thereto will raise or lower the, said valve proper 42, by means of the plungers 49, attached thereto. a slidable lit in the ink container 41, as at 58, and slidably mounted as at 50, the plungers 49 being in contact with-the wedges 48, there being springs 51 super-imposed so as to hold the heads 52 of the plungers 49 against the wedges 48.

In order to assure the proper registering of the ink on the material 10, to be printed,

v I have provided an adjustment as follows:

It being understood that the ends 38 are slidably attached to the driving inembers 39, as heretobefore stated, the internal gear 53, axially located on one of the ends 38, meshes with the pinion 54, rotatively mounted in the driving member 39, and having a hand wheel 55 suitably attached thereto, by means ofwhich the position of the stencil 32 may be varied, there being graduations conveniently placed as at 56 and a line 57, to. designate the amount of variation thereof.

It is therefore obvious that I have provided a means of inking stencils and also a mcansof varying the relative positions of the stencils, so asrto assure the proper registering of said imprints with one another, as-is required to properly secure the desired pattern or design to be printed on the material.

While I have above described the preferred form, construction, am'l'arrangement of the several elements employed, it will be understood that the device is, nevertheless susceptible of considerable modification therein, and I therefore reserve the privilege of resortingto all such changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new, and desire-to secure by Letters Patent of the -Unit'ed. States is as follows '1. In a machine of the class described, a.

stencil member .of cylindrical .shape, an mkmg member in said cylindrical member, a concentrically arranged cylindrical pad within said inking member, an ink resermember, having a longitudinal V-shaped opening in the bottom thereof adjacent said inking pad, and a longitudinal V-shaped valve disposed over said opening adapted to be raised and lowered thereinto for controlling the flow of ink from said reservoir to said inking pad. I

2. In a machine of'the class described the combination 'with a cylindrical stencil member rotatively mounted, of a stationary ink reservoir disposed within said stencil member and extending the full length thereof. said reservoir having an inlet at the top and a discharge opening at the bottom thereof, valve mechanism disposed over said opening for controlling the flow of ink therethrough, a spring for normally urging said valve upwardly to open said discharge opening and externally controlled Wedge mechanism for holding said valve mechanism in a suitable position against the pressure of said spring. p

3. In a machine of the class described, an ink reservoir comprising a semi-circular trough having a longitudinal opening extend ng from end to end of the bottom thereof, said opening having bevelled edges, a valve comprising .a longitudinal Wedge shaped member extending from end to end of said trough, valve rods secured substantially at the ends of said wedge member and deending' from the frame of said machine, en'- argements on the upper ends of said valve stems, springs for normally holding said valve stems in an elevated position, and a slidable rod having inclined blocks thereon adapted to engage said enlargements and urge said stems and valve downwardly against the pressure of said springs.

4. In a machine of the class described, a means of inking. stencils by means of a filler attached to a tubular member, llel dstation ary, an aperture located at its lower periphery, an ink conta ner attached to the said tubular member, and a valve arrangement comprising. a valve proper, extending the entire length of the said ink container, having a V shaped portion to cover an aperture located at and extending the entire length of. the said ink container, and a means of opening and closing the last mentioned aperture. v

5. In a machine of the class described, a means of inking stencils by means of a filler attached toa tubular member, held stationar an aperture located at its lower periphery, 'an ink container attached to the said tubular member, and a valve arrangement comprising a valve proper, extending the entire length of the saidink container, having a V shaped portion to cover an aperture located at y and extending the entire length of the said ink container, and a means of opening and closing the last mentioned aperture, b means of a rod ,slidably being in contact with the said wedges, located in the sai tubular member, having springs superimposed so as to hold the a hand wheel attached thereto, which will heads of the said plungers against the said 10 slidably operate the said rod so that wedges wedges.

5 attached thereto will raise or lower the said In testimony whereof I have aifixed my valve proper by means of plungers attached signature. thereto and slidably mounted said plungers VICTOR ROSATO.
