BRA'IDING- SPEClFKCATION forming part of Letters Patent No. 717,415, dated December 30, 1.902.

Application filed November 9, 1,399. Serial No. 736,424. (No model.)

.To ct whom, t may concerns Be it known that I, BERNHARD Kissen, a subject of the Emperor of Austria-Hungary, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invented certain new`and useful Improvements in Braiding-Machines; and I do hereby declare the following tobe a full, clear, and exact description of theinvention, such as willenable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this speciiication.

A machine according to this invention is specially adapted for covering ropes, cords, 'or cables with braid to form an outer covering therefor. Such a braiding-machine differs from the hitherto usual vertical braiding-machines by having a horizontal axis and is characterized by the fact that the bobbins corresponding to one group of braiding-strips are moved alternately to and fro on the spindles (which are locatedv opposite ,to one another) of two disks or spiders (hereinafter called spiders) which rotate in the same direction and at the same speed, so that the said bobbins travel along a wavy line on the cylindrical surface described byv the spindles, While the other group of braiding-strips rotates between and in direction opposite to that of the two spiders, so that from the two groups of threads of the braiding-strips there is formed a braid that surrounds the rope or cable, which moves continuously through the hollow pivots of the spidersand a central bush. Each braiding-strip consists cfa number of yarn-threads which must lie parallel braiding-strips whose bobbins are alternately moved over from the spindles of one spider to those of the other and which therefore travel in a wavy path these thread-guides consist of inwardly-opening forks which have a notch for each thread. These forks are located opposite toone another at a certain distance apart, so that the threads of the braiding-strips rotating in the central plane can pass between them, and they approach each other only fora short time during the transfer of the bobbins for the purpose of insuring the transfer of the braiding-strips from the right-hand forksl to the left-hand forks, or vice versa. The transfer of the bobbins from one spider to the opposite one is caused byV oscillating levers, and the bobbins are held in their position for the time being against the pull of the braiding-strips by spring-pawls, which are released as soon as the levers are set in motion. The accompanying drawings illustrate an example of such a braiding-machine in which eight braidingstrips are used.

Figure l shows a vertical section of the machine, symmetrical portions being shown only once and the horizontally-arranged transmission-shafts appearing turned up into the vertical plane. Fig. 2 is a sectional side elevation of the braiding-machine, in which for the sake of clearness certain parts are omitted. Fig. 3 is a development of the braiding-paths.

Fig. 4 shows analogously the curved grooves that operate the levers. Fig. 5 is a side View, and Fig. 6 a plan, of a thread-guide. Fig. '7 is an inside view of the arrangement of the thread-guides relative-to the bush. Fig. 8 is a development ofthe curved grooves by means of which the th read-guides are actuated. Fig. 9 is aside elevation, and Fig. lO a cross-section, of the braided rope or cable.

, The parts d andkb are two rigidly-fixed heads, which are located opposite to each other and are turned cylindrical at their inner ends and which form the pivots for the rotating spiders c. One head a has at its inner end a cavity for the bush d, which serves to compress the braiding, while both heads are bored out for the passage of the rope or cable c. The spiders c, each of which carries `four spindles f .of square cross-section, are rotated at the same speed and in the saine direction by means of bevel-wheels g, which are mounted on their hubs and which engage the bevel-wheels h of ICO vthe corresponding shaft 'L'.

the shafts i, so that the `spindlesfof the one spider are always located opposite to those of the otherspider. The four bobbinsj, on which the threads of the braiding-strips lc of the one group are Wound, can therefore be moved during their rotation around the axis of the machine from the right-hand spindlesf to the left-hand ones, and vice versa. Each bobbin j is rotatably mounted on a sleeve Z, which lits the square spindle fand is rigidly fixed to a frame fm, that carries a tension device. (Not shown in the drawings.) The bobbins 'j are moved from spindle to spindle by singlearm levers n, which are pivoted at o on the hubs of the spiders c and embrace the spindlesfwith their forked ends and which are oscillated by means of sliding rods p, that engage the curved grooves of disks q. Each disk q is loosely mounted on the hub of the corresponding-spider c and is driven at the same speed as the spiders c, but in the direction opposite to that of the spiders, by a bevelwheel r of a hollow shaft s, that surrounds On each of the disks q there are fixed four arms on which are mounted spindles o, which are circular in cross-section and are adapted to carry the bobbins tt, that contain the yarn-threads that form the four braiding-strips w of the second group. In the present case the yarn of each braiding-strip w is distributed on two bobbins u, which can therefore be much smaller than the bobbinsj, while containing the same length of yarn. From the bobbins u the yarn passes over the ends (which are bent inwardly and screwed together) of the arms t and join together to form a braiding-strip w in each of the four radial sheath-like thread-guides which are attached to the arms Zand carry at their inner ends perforated thread-guide plates fy. The lthreads of the braiding-strips 7c, proceeding from the bobbins j, are led near to the bush CZ through thread guide forks Z, Figs. 5 and 6, which are turned with their openings inward-71. e., the openings or notches of each fork Z are turned toward those of the fork Z opposite to it. These forks are mounted on stems 3,which carry square bosses 2 and are horizontally movable in supports 4E, fixed to the spiders c, while by their inwardlybentinner ends they engage in curved grooves 5 of rings, which are fixed rigidly to the heads a and b, respectively.

In order to prevent the bobbinsj from being drawn inward by the tension of the braiding-strips Zt proceeding toward the bush d, there is mounted on each lever n a springpawl 7, which as soon as the bobbin arrives from the opposite side snaps in behind the projection 8 of the bobbin-framem, and thereby holds the bobbin fast. This pawl is disengaged when the lever 'n begins to push the bobbinj inward.

The driving of the machine is effected by the main driving-shafting 9, which carries at each end-a bevel-Wheel lO, that forms a reversing motion in combination with a bevelwheel 11, fixed on the shaft t, and a bevelwheel 12, keyed on the hollow shaft s. The shafts i and s therefore rotate in opposite directions, but at the same speed.

For the purpose of facilitating the changing of the bobbins j the bevel-wheels 7L are held in position to gear with their respective gears g by a sleevesecured to its shaft t' by a lock-screw, Fig. l, so that by loosening the latter the said bevel-gear h can be` moved along the shaft out of gear with g, thus permitting the rotation of one spider c independently of the other.

When working, the bobbins j are carried in a circle around the rope e to be braided and are at the same time pushed across by the levers n alternately toward the one side and the other. The braiding-strips Zt, which must follow the movement of the bobbins, travel along the wavy line shown in Fig. 3, while the braiding-strips 'w move continuously in the central plane of the machine. In this manner there is formed in the present case an eight-stranded braid in which each strip of the one group crosses each strip of the second group.

Figtisadevelopment of the curved grooves which are arranged in the disk q and which set theleversnin motion by means of the sliding rods p. In each disk there are two sliding rods which are located on lines radiating at an angle of one hundred and eighty degrees from each other and engage in the groove indicated by full lines, which is arranged in the flange of the disk itself, and also two other IOO sliding rods, which are likewise located on lines radiating at an angle of one hundred and eighty degrees from each other, but engage in the groove indicated by broken lines,

which is located on the inner surface of a bi partite ring 14, screwed to the disk. Each lever 'n pushes the bobbing', located in front of it, upon the spindle fof the opposite spider c and thereupon returns at once to its normal position, so that it avoids the thread-guide sheaths x, which pass between the ends of the spindles f. The perforated thread-guide plates y hold the several threads of the strips zu beside one another, and the threads of each braiding-strip 7c are led through the notches of the thread-guide forks Z, which follow the movement of the braiding-strips.

In Fig. 8 there is showna development of the curved grooves 5 of the abutment-collars 6, in which the outer ends of the fork-stems 3 engage. As soon as a bobbin j is pushed over the fork Z, guiding the corresponding braiding-strip Zt, and the fork located opposite to it move inwardly toward each other, so that these forks almost touch while the threads are being transferred from the one fork into the other. Thereupon the two forks separate again in order to provide room for the passage of the braiding-strip w, so that while the one fork is empty the other holds the braiding-strip, which by reason of its tension lies close in the notches of the fork.

IIO

A braiding-machine of the kind described possesses the advantage that the rope or cable to be braided can be drawn through the braiding-machine and be braided in a horizontal direction while maintaining the tension at which it comes out of the rope-spinning apparatus.

Braiding-machines according to this invention can of course be constructed for braidings with a different number of strips of that of the machine hereinbefore described.
