Application December 15, 1949, Serial No. 133,200

This invention relates to an apparatus for marking continuously running strands. More particularly the invention relates to marking continuously running strands at regular and predetermined intervals, such strands, for example, as those of a warp sheet, and marking the same during the winding or other manipulation thereof,

such as on a spool or beam. The purpose of the marking is to warn or advise subsequent operators of the length of the strands used during certain textile operations, such as in weaving, knitting, braiding, or the like.

It is an object of the present invention to provide a means for marking a continuously running strand while it is running at high speeds.

Another object is to provide a marking system which applies a controlled amount of marking medium to the high speed running strand.

Other objects and advantages of the invention will be apparent from the drawing and descrip- Figure 5 is a view of an alternative embodiment of the invention. 1

Briefly, the operation of the invention is as follows: a rotatable drum, in contact with a viscous ink supply so that its surface remains covered with a certain amount of the same, said amount being controlled by a scraper bar, is placed under the running strand but not in contact with the same. A bar, transverse of the direction of travel of the strand, is placed abovethe strand and at regular predetermined intervals comes down and forces the strand against the top surface of the ink covered drum thus marking the strand. The transverse bar is actuated by a solenoid which in turn is actuated by a switch associated with an idler or measuring roll which is rotated by the strand or strands passing over the same-and at the same linear speed. The solenoid may also be actuated by a switch associatedwith the driving connections for the spool or beamer or the "means for feeding the strand or strands, such as the driving rolls, and the like. The solenoid may be actuated by an independent timing mechanism 8 Claims. -(Cl. 118234) if desired. Thus marks may be made on the strand or strands at any desired distance apart.

The marking'medium may be of permanent or of fugitive inks or dyes and may be applied to a single yarn as it is being wound into package form of conical, cylindrical or spherical shape for the purpose of indicating a definite yardage between successive marks. It may be applied to the warp as it is being wound on a beamer so that as the yarn is withdrawn in a loom, it is possible to determine when a certain length of fabric has been Woven. The ink or dye must be used in viscous solution in order that the same will not penetrate or strike through onto several courses of yarns when wound, making it difficult to decide where the mark was made.

For a more detailed description, reference is made to the drawing which depicts the invention as the same is employed in connection with a warp. The invention will be described with reference to all five figures of the drawing.

In a roller housing 3, comprising end plates 36! and 3b there is rotatably mounted a shaft 30 to which is fixed, as by keying, a corrugated or grooved roller 4 so that its upper surface extends beyond the upper surface of the housing. If desired, the roller 4 may have a smooth surface. The housing is bolted to a horizontal metal plate 5 which in turn is fastened to a vertical plate 6 which rests onand is fastened to the horizontal metal plateor-panel fl.

Adjacentone side of the housing structure is an ink receptacle 8 comprising a cylinder 9 with screw caps [0 at either end with a plunger ll contained inthecylinder 9 operated by turning the handle l2. The ink, being in azviscous state,

is forced by the plunger through the feed line [3 and through the ink inlet opening l4 extending across the surface of the roller 4. Thus, as the roller 4 is turned, its surface is covered with ink picked up by contact with the ink at the opening [4. Although theink cylinder is shown with a hand operated plunger, any automatic hydraulic or. pneumatic plunger may be employed so that a'constant pressure on the viscous ink is maintained thus assuring an even supply of the same capable of being raised and lowered in a vertical plane. In Figures 2 and 3 the arm I! is shown in its raised position. Attached to one end of the arm ii is a vertical rod i8 extending down below the roller assembly and attached at its lower end to a bell crank lever l9 pivoted at 20, the other end of which is fastened to the pivoted arm member 2| which is in turn fastened to the reciprocal rod 22 operated by means of the solenoid 23. Attached between one arm of the bell crank lever i9 and the projection 24 extending inwardly from the vertical plate is a spring 25. The purpose of the spring is to return the bell crank lever to its original position when the solenoid is deenergizedthe operation of which is explained hereinafter.

The solenoid rotates the bell crank lever which in turn lowers the arm ii against the warp thread it? bringing the latter in contact with the roller l. The roller i at the same time is rotated in a direction opposite to the direction of travelof the warp thread. This is accomplished by means of the. movement of the arm ii. To the end of the arm ii, there is attached an arm or lever 25 by means of a washer 2! and cotter pin 28, the arm ll extending through the elongated opening 29 in the lever 25 so that when the arm ii is lowered it moves along the slot or elongated opening in lever 26 to the dotted line position shown in Figure l. The other end of lever 23 is rotatably mounted on shaft 30. A ratchet 3 .3 is keyed to shaft 30 adjacent one end ofroller ii. To the lever 28 there is attached a pawl 3| held down aga nst the ratchet by means of the spring 32. Hence, when the arm I! is lowered, the lever 28 is rotated thus turning the roll 3 in a counterclockwise direction by means of the ratchet 3% and pawl 3i. To prevent the roller i from turning in a clockwise direction when the arm i! is again raised, there is positioned on the lower side of the ratchet as a second pawl 33 held in position against the ratchet by means of the spring The distance through which the arm i'i travels is regulated or controlled by an adjustable stop adjacent the lower arm of the bell crank lever i9. Thestop consists of a' threaded socket set screw 5% extending downwardly through a threaded projection 5? extending outwardly from the apparatus framework, the socket set screw being locked in positicn'and adjusted by means of the lock nut 53. The socket set screw 58 prevents the further counterclockwise motion of the bell crank lever i9 when the latter comes in contact with it and the distance of rotation is regulated by the distance the socket set screw extends beyond the projection 57 to ward the bell crank lever i9.

In order to prevent too large an amount of ink from getting on the surface of the roller, there is provided a scraper bar 35 pivotally 4 beamer or the means for feeding the strand or strands. In the preferred embodiment shown, however, the energization of the solenoid Z3 is derived from the idler or measuring roll The measuring roll is driven by the strands passing over the same. The strands or yarns in turn pulled through the apparatus from the creel by the positively driven beainer (not shown). Fixed to the shaft 9 carrying the measu g roil SE is a pinion 4! in mesh with a gear Z2 secured to shaft d3 carrying a disk i l of insulating material provided with an outwardly ektending projection or pin 15.01 insulating iii-ateial near the periphery thereof. Adiacent the k is a switch 3-3 which comprises a metal oar il securely fastened at one contact point '33 but not in contact with the other contact point We of the switch. As the disk i l is re died the projection to comes into contact with the metal piece or bar 4? forcing the same against the contact point 49 thus closing the circuit to the" solenoid 23. When the projection passes over the bar 41 the latter springs to its normal. position opening the circuit to the solenoid 23. -eans of this arrangement the solenoid E3 is actuated at regular intervals, e. g. each time roll 33 makes a predetermined number of complete revolutions. If desired roll 33 may be positively driven in which case a second roll 59 is empioyed in conjunction therewith as shown in Figure 5. Roll 5% is placed above roll 39 in the same plane and driven at the same peripheral speed. ar'- or other material is passed between the rolls 38 and thus being driven or pulled through the marking mechanism.

The gears ii and 32 are selected to desired yardage between energization of the-sclenoid 23 by the closing of switch 25 by the projection 35. These gears maybe replaced by any form of conventional gear-reducer to give the desired spacing between markings which be frequent or widely spaced depending on the precise purpose of the marking.

The electric circuit for energizing the solenoid 23 comprises a line 5! connecting one terminal of the solenoid with switch 535, line 52 connecting the other terminal of the solenoid with one side of a current source 53, and a master control switch 5 2 in a third line 55 connecting switch =26 to the other side of the current source 53.

The operation of the above described apparatus is as follows: when the spring metal bar 41 closes the circuit to the solenoid 23, the arm 22 is shifted to the right, as viewed in Figure 1, this in turn rotating the bell crank lever i9 give the in a counterclockwise direction thus Lringing the mounted at 36 and adjustable to and from the roller t by means of the screw 3? extending through the lower end of the scraper and seated in the roller housing 3 and acting against the spring 38 between the scraper and housing. The scraper insures the same amount of ink on the surface of the roller in contact with the strands of warp thread at all times. Any suitable scraping means may be employed such as a doctor blade, scraping bar, roller, and the like.

The energization of the solenoid 23 is preferably effected intermittently at intervals which correspond with known lengths of the strand or strands. from the driving connections for the spool or Thus its energization may be derived.

arm i1 down against the warp thread and to the dotted line position shown in Figure i. In this position the strands come in contact with the corrugated or grooved roller and by. each strand falling into a groove on the surface of the roller it is completely submerged in the viscous ink. When the arm it moves downward, it rotates the roller 4 thus insuring a smooth, evenly inked surface when the strands come in contact with the same and at which time,'i. e. strand contact time, the roller has ceased turning since the arm ll has then come to rest in its lowermost position, shown by the dotted. lines in Figures 1 and 4.

When the projection 45 moves past the spring metal bar 4?, the solenoid 23 is deenergized and the spring 25 acting on the bell crank lever it rotates the same in a clockwise direction thus returning the arm I! to its uppermost position,

shown in Figure 1, out of contact with the strands of warp thread. The warp thread, of course, returns to its natural, traveling course through the apparatus shown by the solid line in supplies, such as in U. S, 2,298,888 to Kaufman but without the necessity to mark the yarns during knitting. For this purpose, the frequency of marking of the several beams forming the source of supply for the several warps may be the same and adjustably-spaced observationstations similar to those of the patent maybe provided; In the alternative the frequency of markings of the several warps may be related inversely to the rates of speed of the several warps sothat coincidence of the markings of each warp occurs at definite intervals which may be timed at a single observation station or watched at two or more stations suitably'spaced apart along the yarn travel.

It is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined in the appended claims.
