Application filed August 6, 1910. Serial No. 575,917.

To all whom it may concern:

Be it known that I, ROBERT Baum, a subject of the King of Great Britain, and resident of West Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Selvage- Printing Machines, of which the following sion on other classes of fabrics, such as those 1 formed with a loose weave or with any considerable nap. It has therefore been one of the main objects of my invention to provide an improved selvage printing machine adapted to emplo a heavy pigment or bronze ink that wil make a clear and distinct impression on all classes of fabrics, and in carrying this particular object of my invention into effect I make use of a stencil member having stencil openings therein, representing the desired name or mark, or both, to be printed on the fabric selvage; the printing operation being effected by supplying ink of the desired character through the stencil openings onto the surface of the fabric selvage. I

As it is necessary to the proper operation of a printing machine employing a stencil member and co-acting inking means, that the stencil member should bekept as free as "ossible from any undue accumulation of ink thereon, which would tend to clog up the stencil openings, which are necessarily ver small in a machine of this character, an so interfere with the printing operation, I have constructed an present machine in a manner to avoid such an undue accumulation of ink on the stencil member. Such construction, which constitutes an important feature of my invention, consists in loeating the ink-outlet containing wall of the ink reservoir in direct contact with the inkreceivin' side of the stencil member and providing t e same with a shut-off at such point.

In. this manner the ink supply-may be shut off whenever desired without any surplus 1 being supplied to or left on the stencil membell;

Another feature of my invention is the provlsion of .means for assuring the same speed of movement of the fabric to be print ed-and the stencil member while in contact I with each other during the printing operation, so as to avoid relative movement between the same and the consequent-liabilit of a blurred and indistinct imprint being e footed. This means consists in making the stencil member in the form of an endless sheet and supporting the same with the i working run thereof in close contact with the fabric whereby it will be moved with and by the same; said fabric being positively fed ;through the machine by suitable feeding means. As a means to effect a positive enfgagement of the stencilmember with the fabric when being fediby the latter it is @preferably formed with a roughened or burred surface,

The fabric or web is usually in the form 3 of a roll from which it is unwound as it is fed through the printing machine, and as there is more or less irregularity both in the width' and in the winding of the fabric, it

will be understood that the selvage edge thereof will, feed through the machine in an .irregular or crooked line instead of in a straight line. It therefore becomes necessary that some provision be made to accommodate this irregularity in the path of movement of the selvage through the machine in order to assure the proper cotip'eration of the printing means therewith.- This provision, inaccordance withmy invention and as an important feature thereof, consists in adjustably supporting the stencil member in a manner to permit of its being readily shifted or adjusted to follow an irregular"- ity in the path of movement of the selvage in its passage through the machine;- suitable manually-operated controlling means preferably being provided in combination with the adjustable stencil member. to provide for its ready and convenient adjustment.

These several features of my invention and others not hereinbefor'e mentioned but which will be hereinafter described, are embodied in the machine illustrated in the accompanying drawings, in which- Fig'ure 1 is a side elevation of a selva ge printing machine embodying my invention.

' tie-rods. These side frames 2, 2',

.mg end of the machine and is I print only one selvage edge 0 passing thrpugh the machine, is located at operative engagement with the stencil. Fig.

4 is a-similar view showing the ink presser moved to inoperative position. Fig. 5 is a bottom view of the ink-reservoir and certain associated parts; Fig. 6 is a vertical section through the ink-reservoir and certain associated parts, the section, enlarged, being taken on line 66 of Fig. 1. Fig. 7 is a view of theinlf presser and associated parts contained within the ink-reservoir, looking from the side opposite that shown in Fig. 6. Fig. 8 is an enlarged detail of one end of a I bed-roll over which the fabric andstencil pass.- Figs. 9 and 10 are plan and edge views respectively, of the stencil, and Figs. 11' and 12'are plan and edge views respectively, of an auxiliary feed belt for cooperation with the stencil.

' Similar reference. characters designate like parts in the several figures of the drawings.

The main supporting frame upon which the several cooperating parts of the machine are mounted may be of any suitable construction, that frames 2, 2, connected together bysuitable are provided with journal bearings inwhich are journaled the opposite ends of a series of shafts carrying the rollers b which the fabrio is supported and guide in its passage through the machine. One of these rollers, indicated at 3', is located at the front or feedadapted to have placed thereon the roll of fabric a to be printed. From thisroller 3 .the fabric passes to a bed-roller 4 for cooperation with the printing mechanism, and from thence to a winding-up roller 5' which operates as a means to draw or feed the fabric through the machine. During such passage of the fabric through the machine it preferably will be engaged at opposite sides of the bed-roll 4 by twotension rollers6, 6, which are located in a plane below that of the other rollers and operate to cause the fabric to pass over the bed-roll 4 under proper tension.

The feeding or winding-up roller 5 will preferably be operated .by power, although it may be operated by hand and in case is shown as being provided with a' handwheel 5' for such purpose.

The printing mechanism, bein adapted to g the fabric shown comprising two side the present one side of. the latter and is here shown as mounted on the side frame 2'. r This printing mechanism, as before stated, comprises a stencil member 7, in the form sheet, which, is mounted on two pulley wheels 8, 8, jo'urnaled on stud shafts 9, '9, projecting from one side of a vertical frame or standard 10; the stencil being supported by the said wheels with its lower horizontal run in position for contact with the selvage a of t e fabric as it passes over the bedroll 4.

The inking means for co-acting with the stencil member 7 to supply ink thereto comprises an ink-reservoir 11 detachably connected to the standard 10 with its lower wall 12 containing the ink-outlet 13 in direct con tact with the upper or ink-receiving side of the lower run of the stencil member; the delivery of ink throu h said outlet onto the stencil being control ed by a shut-off in the form of a slide 14 mounted in ways imthe outlet containing wall 12 as shown.

in direct contact with the stencil, the ink, when permitted to feed or discharge through the outlet-onto the stencil, will be confined of an endless- B thus having the ink-outlet containing 'wal within the walls of the outlet and thereby prevented from unduly spreading and accumulating upon the ink-receiving side of the stencil; such control of the ink being permitted by reason of 1ts semi-liquid condition.

By reason of the semi-liquid condition of the ink, which does not permit it to readily pass or flow through the pattern openings of the stencil,' it is desirable that some means should'be provided for pressing or forcing the ink through said opemngs. For such reason I have provided a presser 15 in the form of a pivoted dog supported within the ink-reservoir with its lower-end adapted, when in operative position, to pro ject at an incline t rough the ink-outlet 13 into contact with the ink-receiving side of the stencil and operate to press the ink through the openings of the stencil during i the feeding movement of the latter. This presser 15 is pivoted intermediate its ends at 16 to an arm 17 of a shaft 18 which 18 journaled in opposite walls of the ink reservoir (see Fig. 6) and provided at one end thereof with a crank arm 19 having connection with a handled operating rod 20 which extends at its operatmg end to a convenient position to be gras ed by the o erator at the front or fee mg end of t e machine as shown. By means of this operating rod, the shaft 18 may be rocked 1n one direction to move the presser to opera tive position in pressing engagement with the stencil as shown in Fig. 3, or in the opposite direction to move'the presser to inoperative position within the lnk reservoir as shown in Fig. 4. A spring 21 hearing u on the inner or rear end ofthe presser 15' will 0 erateunder proper conditions to automatically rock the presser to its operative position of engagement with the stencil when brought to a position opposite the ink-outlet of the reservoir, subsequent to' the opening of the shut-01f. It maybe, however, that the heavy ink will in. some cases act to prevent the prompt and complete movement of the presser to such position when brought opposite the ink-outlet, and for such reason I provide an additional means for positively assuring the movement of the resser to operative position at such time. his means comprises a fixed pin 22 on the wall of the reservoir. arranged in such position that when thepresser is being moved to operative position by the turnin of' the shaft 18, it will be engaged bysai pin and directed thereby to its said operative position in engagement with the stencil, as shown in Fig. 3, in which position it is adapted to be positively held durin the subsequent printing operation by suitable locking means, such for instance, as a pin 20 carried b the operating rod 20 and adapted to be inserted into a suitably positioned opening 20" in a fixed part, such as the standard 10, as shown in Fig. 2. That wall of the inkoutlet toward which the stencil feeds, indicated at 23, operates on the stencil as a scraper, because of which the ink has a tendency to accumulate or harden thereon. As a means to avoid this, I have provided a brush 24 for .acting against the walls of the ink reservoir at its outlet-opening to prevent undue accumulation of ink at such point. -This brush is preferably attached to the shaft 18 to be operated thereby, and is so arranged thereon relatively'to the presser that it will be in a positionaway from the ink-outlet when the presser is in operative position as shown in Fig. 3, and will be moved across said outlet when the presser is moved to its inoperative position, as shown in Fig. 4. Any additional movement of the brush, accomplished by rocking its supporting shaft 18, may, of course, be given if found to be necessary. v

The brush 24, in addition to performing its cleaning function as described, also operates to stir up and agitate the ink within the reservoir, and as a further means for performing this latter function, a plurality of arms 25 are also att shed to the shaft 18 to be movable therewith when operated by the rod 20 or otherwise.

The shut-off for the outlet of the inkreservoir may be operated to control the opening and closing of said outlet in any desired manner, but I prefer to provide a means for operating the same which may be conveniently controlled by the operator at the front or feeding end of the machine,

where the presser and its associated parts are also controlled, as just described. This means, as herein shown, comprises a rock- .shaft 26 journaled in the standard 10 and having a forked crank-arm 27 engaging the at .its free or operating end to a convenient position to be "grasped by the operator at the feeding end of the machine as shown.

Longitudinal movement of the rod 30 will operate to rock the arm 27 and move the engaged shut-off back and forth to control the ink-outlet as desired.

The printing mechanism, comprising the stencil member and co-acting inking means as described, should preferably be contained within a closed chamber in order to protect the same from dust, etc., and the lnkfrom evaporation, and to provide this chamber I have provided the standard 10 .with a laterally projecting flange or wall 31 of proper form and width to bring within its edges the printing mechanism, and haveattached to the front edge of this flange 31 a covering plate 32; the latter bein removably attached to the flange 31 by sultable fastening means, such as latch devices 33, 33, in order to permit convenient access to the inclosed printing mechanism.

The ink-reservoir may be of any desired form or construction and be provided wit-h any suitable means for filling the same. As shown in the present case, and more clearly in Fig. 6, it is arranged with one end thereof projecting through a corresponding opening in the standard 10 to a point outside the printing mechanism chamber just described, where it is provided with an ink filling opening 34. This construction and arrangement of the ink reservoir permits of its being conveniently filled whenever necessary without requiring access to said chamber for such purpose.

The stencil member 7, as before stated, is preferably fed by the engagement of the moving fabric therewith, instead of by independent feeding means, so as to move in complete unison with said fabric and thereby assurc clear and distinct printing being efl'ected. ,To positively assure such movement of the stencil member with the fabric, the stencil is preferably provided with a roughened or burred surface at one side thereof, as at 35, formed by perforating the same,'which assures a positive engagement between the stencil and fabric as they pass between the bed-r0114 and the cooperating up-turned rear end 28 of the shut-off slide 14, and a crank arm 29 connecting with a handled! operating rod 30 which extends 5 in combination, web feedin means, an endrubber,-at that end thereof which engages the selvstge. "As a further means to assure the feeding of the fabric and the stencil incomplete unison, I have rovided a belt 38 having .a roughenedor urred surface as shown and otherwise a duplicate of the stencil 7 except as to the stencil openings, which abl mounted in ways 44, 44, on the frame 2 or movement in a direction transversely to the direction of feed of the fabric .throu h the machine, whereby the printing mec anism may be bodily shifted oradjuste'd to follow any irregularity in the path of movement of the fabric selva e through the machine; a lever. 45 pivote at-one end to the main frame at 46 and pivoted at a point between its ends to the sliding-bed at 47 serving as a convenient means to enable the operator to adjust the position of the printing mechanism as required.

The opening 48 in the top wall of the printing mechanism chamber, closed by a hinged cover 49, serves as a' convenient means to permit the operator to readily examine the stencil whenever desired for the and inking purpose of ascertaining its condition, that is, whether it is sufliciently clean and free from .ink to assure proper printing What I clalm is: 1
