MECHANISM FOR DRAWING YARN OR THREAD INTO CARRIERS.

SPECIFICATION forming part of Letters Patent No. 516,147, dated March 6, 1894.

Application filed Jnne 29,1893.

To all whom it may concern.-

Be it known that we, HORACE WYMAN and JOHN A. CLARK, of Worcester, county of Worcester, State of Massachusetts, haveinvented an. Improvement in Mechanism for Drawing Yarn or Thread into Carriers, of which the following description, in connection with the accompanying drawings, is'a specification, like letters and numerals on the drawings representing like parts.

Looms for weaving tufted fabrics, among which may be named carpets, employ tubular carriers into which are drawn the ends of the tuft-yarns on the tuft-yarn beams, said carriers being employed to put the tuft yarns carried by them into the sheds formed in the warps in the loom, said tuft yarns forming the separate transverse rows of tufts.

Our invention comprehends an apparatus for drawing the tuft yarns into and through the said carriers or tubes.

In accordance with our invention, a yarn beam provided with a series of tuft yarns, and also a series of carriers or tubes to receive the said yarns from said beam, are mounted in a carriage adapted, in the manner in which we have herein chosen to embody our invention, to slide longitudinally on a suitable guide or track so as to bring one carrier or tube after another in proper position with relation to a drawing-in book carried by a hook bar, the said hook, as herein shown, being attached to a longitudinally reciprocating bar, a suitable feeding-mechanism effecting the relative change of position of the carriage, and the bar to which the hook is attached, so that the hook may enter the carriers or tubes in the desired order or sequence. For the greatest simplicity and convenience it is preferred that the carriage holding the tuft yarn beam and series of carriers or tubes be moved relatively to thepath of reciprocation of the drawing-in hook.

Another part of our invention consists in a guide which is adapted to direct the drawing-in hook unerringly into the open ends'of the carriers or tubes; and also to exactly center or position the ends of the carriers or Figure 1 is a plan view of a sufficient por- Serial No. 479,124. (No model.)

tion of a drawing-in machine to enable our invention to be understood,part of the frame being omitted and other parts being broken out centrally at the sides to save space upon the drawings. Fig. 2 is a side elevation of the particular parts of the apparatus shown in Fig. 1. Figs. 3, 4 and 5, are enlarged details showing the carriers or tubes mounted in the carriage and with the drawing-in hook in position in one of the carriers, the section for Fig. 5 being on the line on, Fig. 3, the section for Fig. 3 being on the line at, of Fig. 4. Fig. 6 is a detail of some of the parts instrumental in opening or controlling the clutch pulley device for stopping and starting the machine. Fig. 7 is a detail showing part of the feeding mechanism for the carriage.

In the drawings, let A represent a bed-plate of suitable size and shape. Upon this bedplate is ereotedasuitable frame-work A, and a stand A having depending brackets A the parts so far referred to constituting what may be designated as the frame-work.

In Fig. 1 we have omitted from the drawings the stand A and the bracket A located at one side of the machine, but it will be understood that the said stands and brackets are alike. The stands A support a guide rod B, and the lower ends of the brackets A support a guide rod B, said guide rods forming suitable tracks for a carriage B The end pieces of the carriage, which is free to slide on the guide-rods referred to, are suitably shaped to receive thejournals of the tuft yarn beam B provided, it will be supposed, with a series of yarns wound side by side, there being as many yarns as there are tufts to be made in a transverse row of tufts in the fabric to be woven. The carriage has suitable brakes shown as levers B controlled by suitable springs B which brakes by their action upon the heads of the beam prevent rotation thereof due to momentum.

The upper part of the carriage B is herein 5 edge of the bar 4E being preferably level. The notches referred to in the upper edges of the bar 3 receive in them the backs of the carriers or tubes G attached to the barD, preferably a wooden bar, it having connected to it sprlng catches D adapted to engage the links of an endless chain when the said bar with its carriers or tubes is to be used in a loom, the

said bar and spring catches being common to.

United States Patent No. 454,414, dated June 16,1891. To keep the series of carriers or tubes and bar D in and down firmly upon the carrlage during its movements, we have provided a presser 01, shown as a bar suitably attached to arms d of levers d having suitable journals supported in stands d attached to a part of the carriage E the tipping of said levers (if forcing the presser down upon the said series of carriers or tubes, as best represented 1n Fig. 3. The bar d and its actuating de vices constitute a locking device to keep the series of carriers in place.

The frame-work A has suitable bearings for a shaft 2, upon which is fixed one member e preferably of a friction disk or pulley, the other member e of said disk or pulley loose on said shaft having its hub grooved as ate to be embraced by the arms of a suitable fork 6 attached to a rock shaft 6 having an arm e connected by a rod 6 to a suitable treadle a The arm 6 has a projection e which when the loose clutch pulleypart e 1s out of contact with the fast clutch pulley part e, is held in such position by a locking device e shown as a hook pivoted at e Aspring e connected to a pin 6 of the arm e acts normally to move the loose clutch pulley part e into driving contact with the fast clutch pulley part c, and said spring will operate to start and drive the machine whenever the operator turns the locking device so as to free the arm e". The shaft 6 carries, as herein represented, two cams f, f, shown as inclined disks, the faces of which act upon and move respectively two levers f f pivoted respectively at f, f", the lever f carryng a feeding pawl g, and the leverf a feedlng pawl g. During the rotation of the shaft 6, these levers are moved toward and from each other, substantially in unison, and the carriage 13 will be moved in one or the other direction upon the tracks referred to, according to which of the pawls g or g is permitted to engage the teeth or projections 6, the point of engagement of either of said pawls with the said teeth, being at one side the path of movement of the drawing-in hook h. To determine which of the pawls referred to shall engage and move the carriage in one or the other direction, we have provided the ma chine with a pawl controller 9 the said pawl controller being represented as a lever attached to a rock shaft 10, shown in full lines in Figs. 2 and 7, and in dotted lines Fig. 1, said shaft having its bearings in suitable ears at the upper end of an arm 9 suitably attached to the frame-work; The controller 9 is represented as connected to the rock-shaft 10, so that one arm of the controller is longer than the other arm. The rear end of the rock shaft 10 has attached to it an arm 9 to which is jointed a link g attached at its lower end to a treadle g pivoted at g on a suitable stand 12, a spring 13 normally acting upon the said treadle to keep the long arm of the controller elevated in such position as to keep the point of the pawl 9' out of engagement with the teeth of the said carriage, letting the pawl work to feed the carriage in the direction of the arrow shown in Fig. 1. If, however, it is desired to move the carriage automatically in a direction opposite said arrow, the operator will put his foot upon the outer end of the treadle g and will throw the pawl g out of operative position and let the pawl g come into operative position with relation to said teeth.

The shaft e carries a crank h, upon the pin of which is mounted a link It provided with a stud 7L3, which for the best results is made adjustable on said link 71?, the'end of said pin passing through a slot 14, shown in the bar 7L4, to which is suitably attached the drawing-in hook h, said bar being supported in suitable guide-ways h, h erected upon the frame-work. The bar 7L has connected to it a block 7L7, to whichin turn is connected a suitable spring blade h one end of whichis bent or shaped to engage the stud 71 when at the outer end of the slot Ll in the bar 7%, so that said stud as the shaft 6 is rotated is made to slide the bar It longitudinallyin its guides. This spring and slot serve two important purposes, one of which is that if, for anyreason, the drawing-in hook should ineet'with any obstruction in its forward movement toward the carriers or tubes, the spring It will yield before any damage will be done, the second ad vantage being that should the operatoratany time desire to retract the bar 7L while the shaft 6 is at rest, the operator may engage the hand-piece 16 attached to the bar, and move it to the right, the bar during such independent movement, by reasonof the slot 14, traveling along overthe stud 71,

In operation, the attendant of the machine,-the tuft yarn beam and the bar holding the carriers or tubes having been putinto position as represented,-will start the machine and let the drawing-in hook be carried forward and passed through a carrier or tube, as represented in Figs. 3 and 4E, and While in such position will by handlayinto the mouth of the drawing-in hook the end of the tuftyarn opposite and which is to be drawn into the carrier in which the drawing-in hook then rests, and having supplied the drawing-in hook with a tuft-yarn, the said hook will be retracted pulling with it the tuft-yarn, as represented best at m in Fig, 1. Another Way of using the machine is for the attendant to engage a tuft-yarn end and hold it above the bar D in position to be caught by the mouth of the drawing-in hook when the latter shall have been thrust forward through the carrier or tube, the attendant releasing the tuft-yarns as the drawing-in hook starts on its return movement.

This invention is not limited to the use of a clutch pulley or driving mechanism of the exact form represented, or to a feeding mechanism of the particular form shown, as instead we may use any well known or suitable feeding mechanism adapted to engage the part of the carriage supporting the beam to which the carriers or tubes are attached to move it intermittingly and uniformly for the proper distance to enable the drawing-in hook to correctly and unerringly enter the said carriers or tubes. Neither is this invention limited to the exact shape shown for the drawing-in hooks, nor to the exact shape of the locking device or clamp to hold the carriers or tubes in correct position with relation to the carriage.

This invention is not limited to the specific devices shown of a slotted bar and spring between the drawing-in hook carrier and its actuating crank shaft and pulley, as any form of giveaway arrangement between the parts allowing one part to be moved independent of the other will come within the scope of our invention; neither is the invention limited to the specific arrangement of the controller G as any other well known method of controlling either of the two parts to operate as described would be within the scope of this invention.

This invention is not limited to the number of guides, or tubes or carriers, but it is preferred to have one guide for each carrier.
