Application filed Septcmher 13, 1883.

To aZZ whom it may concern.-

Be it known that I,ED\VARD I-I. EISENHART, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in the Art of Preparing Yarn or Thread for Filling, of which the following is a specification.

The invention relates to the art of preparing yarn or thread for filling; and it consists in a process of preparing the yarn, jute, or other material employed as a filling, whereby from a single bobbin or cop any required number of picks of like color may be laid, and then followed by an equal number of picks of a different color, and so on, until the entire bobbin or cop has been consumed.

In describing my invention I will explain the machinery employed and the conseeutive steps followed in attaining the desired end. Ihave employed it extensively in the manufacture of jute carpets, and have demonstrated its entire practicability.

The first and probably the most essential part of the process consists in the peculiar formation of the hank of jute, yarn, or other material used as the filling, whereby the parts of the hank may be so formed as to permit of their being independently dyed in diii'ercnt colors, and be wound upon the bobbin or cop so that the colors of given lengths will alternate, as hereinafter described. The hank of material is formed upon the reel A,illustrated in the accompanying drawings, and the jute or other material of which it is composed is taken by the reel from the spools B.

In carrying out my invention I employ the machinery shown in the drawings, in which Figure 1 is an end view, and Fig. 2 a front elevation,0f the reeling apparatus. Fig. 3 is an end view of the shiftingbar H, hereinafter described. Fig. 4 is a detached view of a portion of the reel A, showing the hank of jute after it has been fully wound and its up- (X0 model.)

Any desired number of spools B may be employed, according to the number of hanks it is desired to form upon the reel at one operation. The reel consists of the horizontal bars 0, secured upon the ends of the spokes D, which radiate from the aXle E. Upon one of the horizontal bars 0 are secured two vertical pins, F, and between the reel and the spools is arranged,in the pockets G, the shifting-bar H, which will be provided with proper guides, through which the material from the spools may pass, in the present instance screw eyes I being employed for that purpose. If the carpet is one yard wide and the reel seventy-two inches in circumference, one length of yarn or jute around the reel will answer for two picks of the carpet, and two lengths around the reel will answer for four picks, which is the number of each color that I have usually employed.

In the operation of forming the hanks upon the reel, where the carpet is one yard in width and the reel seventy-two inches in circumference, I first draw the yarn of jute, &c., from the spool B through the guides I on the shifting-bar II, and wind it twice around the reel 011 the outside of, say, the left-hand pin F, and then (the pins F now being on the upper side of the reel) move the bar II toward the right until its guides I carry thejute between the pins F, and then move it still farther toward the right, in order that the jute may be on the outer side of the right-hand pin F, at which time the reel is given two more coinplete revolutions. Then by the shifting of the bar H toward the left the jute is carried between the pins F and. to the left thereof to its former position, whereupon the reel will be given two more revolutions, as in the first instance, this alternate operation being continued until a hank of the proper size has been formed upon the reel. The line described by the jute as it is moved between and around the pins F is in the form of the figure 8, and is illustrated in Figs. 5 and 6, Fig. 5 showing the line formed when the bar His first moved from theleft toward the right, and Fig. 6 that when the bar II is returned to its initial position.

It will be observed that the hank consists of two parts, a b, connected ata single point, and that the portions of the connecting part (I cross each other alternately at about their center.

and tying them, substantially as indicated in I Fig. 4. The slat carrying the pins F is then dropped (that is, the pins as sustaining said slat on the ends of the spokes D are withdrawn and the slat allowed to lower) and the hank moved off the reel, after which it is dyed in,

say, two colors, the part a, for instance, being scarlet, and the part 1) black, the line of di- Vision between the colors being at the center of the connecting portion at.

The dyeing may be effected in any convenient manner; but I have usually obtained satisfactory results by immersing the part b in the tank of color while the part a is suspended clear of thesame, and then reversing the position of the parts. After the dyeing has been accomplished and the hank dried the jute or yarn will be wound upon the spindle to form the cop, and in this operation the jute, being regularly rewound from the hank,will first give off four yards from its side a, which, for convenience, may be cc isidered black, and then four yards from its twin part b, which is of scarlet hue. Thus it will be observed that there will first be four yards wound upon the cop of black, then four yards of scarlet, and afterward four yards of black again, and so on, the colors alternating on the cop at the end of every four yards drawn from the hank.

The appearance of the cop when wound is approximately illustrated in Fig. 7.

There is nothing more to be done now in the consummation of the invention but to place the cop in the usual shuttle and allow it to travel the ordinary shuttle-race and lay the weft or filling in the customary manner.

It will be plain the color will change in the goods as each four yards of the jute or yarn is drawn from the hank, and that as one yard constitutes one pick there will appear in the carpet four picks of one color, and then four picks of another color, and this without changing the shuttle, bobbin, or cop or interrupting the motion of the machine.

It will appear obvious that by the employment of more than two pins F, I may increase the number of parts in the hank and dye each part with a separate color, thus producing a hank having more than two colors and a cop which will give off the required picks in Various alternating colors to any extent required.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

The method of preparing the hank of filling material,consisting, essentially, in forming the hank in two or more parts, a definite length of material being wound alternately in forming .said parts, securing the material where the latter crosses for the purpose of keeping the parts separated, dyeing the several parts in different colors, and then re'winding to form a cop, substantially as set forth.

Signed at New York, in the county of New York and State of New York, this 14th day of September, A. D. 1883.

EDWARD H. EISENHART.
