CHARLES E. BARNES, OF BOSTON, MASSACHUSETTS, ASSIGNOR, EY MESNE ASSIGNMENTS, TO UNITED STATES CORD COMPANY.

CORD-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 232,920, dated October 5, 1880.

Application nled January 19, 1880.

To all whom it may concern Be it known that I, CHARLns E. BARNES, of Boston, county of Suffolk, State ot' Massachusetts, have invented an Improvement in Cord-"VIaking Machines, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to mechanism for making cord by interlocking the several strands rather than by twisting.

The object of the invention is to make au interlocked solid cord or rope without the employment of a separate core or center-tilling strand, as now common.

In certain cord-making machines now in use working much after the manner of braidingmachines each traveler carries the thread of its bobbin about t-he threads carried by two other travelers, they being at that time stationary, butin that class of machine the cord produced was hollow at its center and had to be filled with a core-strand, and the larger the diameter of the cord the larger the hole.

In the class of machine referred to it is impracticable to form a cord of greater diameter than about live-sixteenths of an inch because of the size of the core necessary to be used.

When a larger core is used the cord-which the said machine was intended to make practically becomes only a cover, which is liable to become displaced.

I have discovered by experiment that the travelers which carry the bobbins upon which are the threads to be united to form t-he cord may, in their operation, produce a solid cord of any desired diameter, provided each traveler is so operated as to cause the thread of its bobbin to appear at the surface of the cord being woven at but three different points during each complete revolution of the travelers, for by so manipulating the travelers their bobbin-threads are so concatenated as to eX- 'tend from one side ofthe cord across the same almost in a central position, the exact center of the cord at such crossing being composed of several ofthe bobbin-strands of other travelers, the said strands then being partially twisted together at the center, these center strands constantly changing, and each cross- 50 ing strand from outside to outside passes diagonally across a crossing strand previously laid.

In this my machine for making a solid cord I employ a series ot' travelers, a traveler-holding plate, and a series of rotatable carriers, and with each carrier a traveler-selector, which determines which of the series ol" travelers shall be taken by the carriers and which left in the traveler-holding' plate.

Figure l represents, in top view, a cordmaking machine embodying my invention, a part ot' the traveler-holding plate being broken away, and a carrier removed to show the traveler-selector and its operating parts 5 Fig. 2, a vertical section ofthe same on the line ma, Fig. 3; Fig. 3, a view of that part ot' the machine looking upward from the line y y, Fig.

2, Fig. 4, one of the carriers removed; Fig. 5, one of the travelers in two positions; Fig. G, a detail of the revoluble cam-plate to op- 7o erate the traveler-selectors. Fig. 7 represents, in top view, such a stop-motion ring as in practice I shall employ on my machine shown in Fig. l; Fig. S, a sectional detail on the dotted line, Fig. 9; and Fig. 9, a section ot' Fig. 7. 75

In Figs. l and 2 of the said drawings, to avoid confusion, I have shown the travelers by simple rings and disks, but it will be remembered that cachot' the said rings or disks represents a traveler' substantially such as is So represented in Fig. 5.

The base a of the machine, supported on suitable legs, has standards b, at the upper ends of which is attached the traveler-holding plate c, it being shown as an annular plate having a series of notches, 2, more or less in number, according to the number of travelers d to be used, such number depending upon the diameter desired for the cord or rope to be made. 9o

The main shaft c of the machine, driven in any usual way, has at its inner end a bevelpinion, j', which engages with the teeth of the two bevel-toothed disks g h, thereby causing them to move in opposite directions. The

bevel-toothed disk g is fastened to sleeve v3, extended upward, as shown in Fig. 2, and the said sleeve has connected with it the rotatable table j. This table has upon it suitable lugs or bca-rings for the shafts 7c 7c', Src., of the carroo riers Z Z', Ste., and is recessed upon its top below the carrier to receive the feet 3 of the travelers, (see Figs. 2 and 5,) and each carrier has a series of notches, 4, in which, at the proper times, are placed the necks 5 of the travelers, which are to be changed from one to another notch, 2, of the traveler-holdin g plate.

The carrier-shafts 7c k have xed upon them gears 7a2, each of which is engaged by a gear, 7c3, each gear k3 being held on a stud, le, in the table j. .Each gear 7c3 engages and is rotated by the center gear, m, fast with the positively-driven bevel-toothed disk h. The gear fm is rotated in a direction the reverse of that in which the tablej rotates, which enables the gears 7c3 in a very rapid manner to rotate the carriers on their own axes as theyare revolved about the axis of the table.

One of the carrier-shafts (the one k) has a second gear, a, fast to the gear k2, and gear n, through intermediate a, carried by thetable, engages the toothed gear a2, which is attached to the cam disk a3, having a camgroove, n4, and rotates the said cam-disk at the proper speed and in a direction opposite that of the table j.

At the left of Fig. 2 I have shown a shaft, o, having a bevelgear, 02, and this' shaft, driven positively by the toothed disks g h, is employed to operate the take-up. (Not herein shown, as it will be of usual construction.)

rIhe travelerselector is composed of two jaws, 1J p', each having a groove, 10, and pivoted on a common stud, 12, fixed with relation to the table. The jaws p p are, by suitable links, 13, connected with levers 14, having a common center, 15, also fixed to the table j, and each lever 14 has a roller or pin to enter the groove a4 in the cam-disk a3. As this disk af* and table rotate, the grooves acting upon the rollers of the levers 14 move them, and turn the jaws p p upon their pivots, thereby causing them to so change their positions that the grooves 1,0 become concentric with the edges of the chambers cut in the table for the carriers, as in Fig. 1, and it will be obvious that when the two jaws are moved to close the gap shown between them in said iigure the two grooves 10 will then coincide and become concentric with the periphery or outer edge or wall of the table.

When the jaws of the selectors are as in Fig. 1, the rollers of the levers 14 being then nearest the center of the cam-disk, the jaws are in position to permit the foot of a traveler held in a notch, 4, of a carrier to enter the groove 10 and pass from the same, so as to be left in a notch, 2, of the traveler-holdin g plate; but when the said jaws are closed, as described, its grooves 10 are in such line as to engage the footof the traveler opposite it, then held by the traveler-holding plate, and take it from said plate and direct it into one of the notches of the carrier, to be carried by it to another notch, 2, of the traveler-holding` plate. In this my machine this cam n4 is so shaped as to pick up every ninth traveler, (there being twenty-seven carriers employed,) and transfer it from the position d2 to that d3 in Fig. 1, or substantially one-third the distance about the machine. In this way the threads of the usual bobbins upon the travelers are passed each one over substantially one-third the number of threads being used, and each thread is caused to appear but three times at the surface of the cord during each complete revolution about the machine of the travelers,which enables the production of a solid cord or rope without a core. This cord or rope has been made the subject-matter of a separate application, tiled March 8, 1880.

The travelers d have side arms, 16 17, the former to guide the main sinker 18, having a tinger, 19, extended or hooked over the tension-lever 20, pivoted upon the bracket 21, the

curved end of the said lever 20 engaging and resting upon the thread after it passes through the regular tension device to be molmted upon the pin 22, the said tension device being shown in Fig. 5 as a flat spring with an adjusting-screw; but this form of tension device may be variously modified. This lever 2O will drop and allow the sinker 1S to descend and strike the usual shipping-ring whenever the thread breaks between the tension device and the cord being made on the machine.

The arm 17 carries an auxiliary sinker, 23, which will be supported by the thread as it passes from the bobbin to the pin 22, or tension device thereon, and should the bobbinthread run out this auxiliary sinker will drop and stop the machine.

rlhe traveler-sinkers are, in Fig. 5, shown in the positions they will occupy when supported by the threads and the machine in operation.

The stopping-ring 25 (not of my invention, but in common use on braiding-machines) has n gers 26, against which either of the sinkers 18 c1123, when permitted to drop, will strike and turn the said ring far enough to disengage a ledge, 32, thereon from a notched bar, 27, which permits the spring 28, connected with the shipping-lever, to shift the driving-belt from the fast to the loose pulley. I shall attach to the upright 33 a double spring, 34, (see Fig. 8,) the arms of which will be acted upon by the pins 35 36 of the stop-motion ring, according to the direction of movement of the said ring when acted upon by one or the other sinker. The sinker 18, when it drops on account of the thread breaking beyond the tension device, strikes the right-hand side of one of the fingers, and the sinker z3 drops if the thread on the bobbin is exhausted or breaks between the bobbin and tension device, and strikes the opposite or left-hand side of one of the fingers.

In other cord-making machines it is customary and quite necessary to watch the machine and stop it by hand before the thread on any IOO IIO

bobbin is exhausted or runs out, or elsefthe j end of the thread will pass beyond the tension de vice before the machine will be automatically stopped, causing much trouble to then pick it up from the mass of threads and connect it with the thread ot' the bobbin to be added, but by adding t-he sinker 23, to operate, as described, in advance of the usual sinker 18, I am enabled to always stop the machine automatically Whenever the bobbin'thread runs out or is broken between the bobbin and tension device, and the end of the thread is thus never passed from the control ot' the tension. When one tension device operates on the thread only outside the bobbin, as before stated, the end ofthe thread passes the tension, and the thread so broken,bein,g` relieved of the tension, always produces an uneven spot in the cord. This the use of two sinkers avoids.

I do not claim the employment of a single sinker alone on any part of the thread; but I am not aware that prior to my invention two sinkers have been used on one carrier and in the manner herein shown and described.

I claiml. In a cordmaking,` machine, a table, carriers thereon, a notched traveler-holding plate, and a series of travelers, and means to rotate the said table and carriers, combined with a travelerselector composed of grooved and pivoted jaws, the links and levers to move the said jaws, and a cam to operate the levers, substantially as described.

2. In a cord-making machine, the table and carriers and means to operate them, the travelers, the traveler-holding plate, the grooved pivoted vibratable jaws, the cam at, and connecting devices between the said jaws and cam, the cam being adapted to open and close the said jaws at the times herein stated during the rotation of the table, to place the grooves in the said jaws concentric with the outer ed ge ofthe said table, or with the chambers in which the carriers move, to thereby enable the said jaws to take each traveler from a notch in the traveler-holder and deliver itin another notch in the traveler-holder substantially one hundred and twenty degrees distant therefrom, and cause the thread upon each traveler in succession to appear at the outside of the cord at but three points during each rotation of the traveler about the machine to produce a solid cord, substantially as set forth.

3. In combination, the traveler, the tension device, the tension-lever 20, and main sinker supported by the thread beyond the tension device, and the siuker 23, to bear upon the thread between the bobbin and said. tension device, the said sinker bein g arranged to drop quickly and engage the usual stop-motion ring` when the thread breaks or runs out, as speci tied.

In testimony whereot'I have signed my name to this specification in the presence of two subscribing' witnesses.
