SPECIFICATION forming part of Letters Patent No. 624,817, dated May' 9, 1899.

Application filed Tulle 14, 1898. Serial No. 683,409. (No model.) l

To all wtowt t may concern:

Be it known that I, EDGAR H. JOHNSON, a

citizen ot' the United States, residing at New York, (Brooklym) county of Kings, State of New York, have invented a new and useful Machine for Making Cables, of which the following is a specification.

My invention relates to cabling-machines generallythat is, 4machines for twisting strands into a cable or for covering-a core with one or more layers of strands; and the special object in view is to provide a oomparatively simple and inexpensive machine which shall be compact in arrangement, so as to greatly decrease the amount of space required, in which the spool-framesshall be set obliquely to the axis of the rotating head, and in which/the spool-framesas they are carried about by the rotating head will maintain a uniformly horizontal position-that is to say, an independent axial movement is imparted to each spool-frame which just neutralizes the effect on the frameset the axial movement of the head. A

Vith these ends in viewl have devised the novel machine for making cables of which the following description, in connection with the accompanying drawings, is a specification, letters and numbers being used to designate the several parts.

Figure l is a plan view of the machine complete, the spools and spool-frames appearing in operative position, the spools for the sake of clearness being shown as empty and the outer portion of the fifth web-wheel in section; Fig. 2, a side elevation ofthe frameand the mandrel and web-wheels ot' the rotating head, the spool-frames and gearing being omitted, but the position of the spools being indicated by dotted lines.; Fig. 3, a plan View, partly in section and on an enlarged scale,

of the rotating head, the outer rows only ofv spool-frames and spools being shown; Fig. 4, a cross-section of the hollow mandrel on the line in Fig. 3, one of the web-Wheels appearing in elevation and the position of the spools beingindicated by dotted lines; Fig. 5, va section on the line y y in Figs. A2 and 3; Fig. 6, a detail view showing the reverse side from that which appears in Fig. 4 of one of the gearwheels carried by all except the first and the last of the Web-wheels; Fig. '7, a sectional view, on an enlarged scale, on the line c a in Figs. l and 2, illustrating mechanism for changing the speed of the drawing-drumg Fig. 8, a detail view, on an enlarged scale, showing the mode in which the strands: are twisted, the beveled end of the hollow maudrel being shown in elevation and the 'die in section; and Fig. 9 is an enlarged detail view corresponding with Fig. 3,sho`wing another modein which motion may be communicated to the shaft which imparts axial movement to the spool-frames.

A denotes the bed of the machine, which is supported bylegsB; C, a'hollow mandreljournaled in boxes F on standards D, which extend above the bed, and E web-wheels, whose hubs 2 are rigidly secured to the hollow mandrel in any suitable manner, as by set-screws 3. These web-wheels andthe parts carried thereby and the hollow mandrelare collectively termed the rotating head. In. the present instance the boxes in which the mandrel is journaled are shown as provided withantifriction rollers 4, made hollow for the sake of lightness, which surround the mandrel. Upon the outer face ot the first web- Wheel E and rigidly secured thereto is a gear-Wheel 5. shown this gear-wheel as supported by a circular flange 6 on the web-Wheel and as secured to the Web-wheel by bolts 7. Motion is imparted to the rotating head by means of a pinion 8, which meshes with gear-Wheel 5. This pinion is carried by a Shaft 9, which is provided with fast and loose pulleys 10 and ll, over which a belt (not shown) passes.

G denotes the spool-frames, and H the spools therein. These spool-frames are so shaped,

In the present instance I have.

the forward ends converging, as to permit them to be mounted obliquely to the axis of the rotating head.' The rear or upper ends of the spool-frames are provided with jour# nals l2, having their bearings in oblique hubs 13, which'are provided with `flanges 14, by which they are riveted or otherwise secu red to the peripheries of the web-wheels. The forward or lower ends of the spool-frames are provided with journals l5, which have their so as to retain wheels I in position thereon,

but at the same time to permit free rotary movement of the gear-Wheels independently of the web-wheels.

23 denotes internal gear-teeth on wheels I,

which are engaged by pinions 24, carried by a shaft 25, which is itself journaled in hubs 26 on the web-wheels. (See Fig. 4in connection with Fig. It is by means of the pinions 24 on shaft 25 th-at the axial movement is imparted to the spool-frames, which neutralizes the axial movement of the head and retains the spool-frames at all times in a horizontal position. Rotary movement may be imparted to shaft 25 either in the mode illustrated in Fig. 3 or in the mode illustrated in Fig. 9. In Fig. 3 I have shown a web 27 rigidly'secured to the box F at the rear end of the rotating head, said web being provided with internal gear-teeth 28. (See Fig. 5 in connection with Fig. 3.)

29 denotes an idler-pinion carried by a stud 30, fixed in the first web-wheel and meshing with internal gear-teeth 2S, and also with a pinion 3l on shaft 25, as clearly shown in Figs. 3 and 5.

In Fig. 9 I have illustrated a modified form of mechanism for imparting rotation to the pinion-shaft. Instead of a web 27 provided with internal gear-teeth I attach to the boX F at the left end of lthe machine, as seen in the drawings, a web 44 provided with external gear-teeth 45, which mesh directly with pinion 3l on shaft 25, thereby doing away with the idler-pinion29.

Any convenient number of sets of spoolframes may be used and any convenient number of spool-frames in each set. Bylengthening the frame and mandrel the number ofwebwheels,and consequently t-he number of spoolframes and spools, may be increased indefinitely. In the present instance I have shown ten spool-frames in each set and four sets of spool-frames and spools requiring five webwheels, the first web-wheel-thatlis, the one appearing at the left in Fig. 3 and the one to which power is applied-not being provided with hubs 16. The third, fourth, and fifth webwheels (see Fig. 4 and dotted lines in Fig. 3) are provided with holes 32, through which the strands pass. The forward end of the hollow mandrel extends through and beyond the standard D, appearing at the rig-ht in Figs.

1 and- 2, the eXtreme forward end of said mandrel being beveled, as at 33. (See Fig. 8.)

34 denotes a die supported by arms 35, extending forward from the standard upon which the forward 'end of the hollow mandrel is jonrnaled. This die condenses the strands, and.l owing. to the rotary movement of the head wraps or twists them about a core or about each other, as clearly shown in Fig. 8. The cable is dra-wn through the machine by means of a drawing-drum J, journaled in bo'Xes K at the forward end of the bed. The cable is passed several times about this drum, so as to take firm hold thereon, and thence passes to a winding-drum. (Not shown in the drawings.) Upon the side of the drawing-drum is a bevel gear-wheel 36, which is engaged by a bevel-pinion 37 on a shaft 38. (See Fig. 1.) Motion is imparted to shaft 38 and through said shaft to the winding-drum by means of a gear-wheel 39, meshing in the present instance with an idlerpinion 40, which in turn meshes with a gear-wheel 4l on a shaft 42. At the other end of shaft 42 is a gear-wheel 43, which meshes wit-h a gear- IOO `closer or shorter will be the twist of the strands, and that as the speed of the drawing-drum is increased, the speed of the rotating head being at all times the same, the longer will be the twist of the strands-that is to say, the strands will lie more nearly parallel to the axis of the cable itself. Awheel 39 is of course provided with holes through which the strands pass. These holes do not appear in t-he drawings, but are similar to the holes 32 in the web-wheels, which are shown in Fig. 4 and are'indicated by dotted lines in Fig. 3.

The operation is as follows: If a core is to be covered, the core is passed through the hollow mandrel and through the die and the strands are wrapped about it at the die in precisely the saine manner that they are twisted together in Fig. 8, the only difference being that where a core is used' the strands are twisted about the core and where no core is used, as in Fig. S, the strands are simply twisted together. In. threading the machine the operator places as many spools in the spool-frames of each set as may be required and makes use of as many sets of the frames as may be required, it being of course wholly immaterial whether all the sets of spoolframes are in use or whether all the frames in each set carry spools. The operator passes Gearthe first, second, and third sets. of spools,

` spools, it being of course understood that the andthe holes (not shown) in gear-wheel 39 receiving the strands from all the sets of third, fourth, and fifth web-wheels and the gear-wheel 39 contain a number of holes corresponding in number to the largest number of spool-frames and spools that can be used inv each set. The strand from each spool passes through the special hole 17 corresponding thereto; but each set of holes 32 receives the strands from all thespools lying back of said hole and the holes in gear-wheel 30 receive the strands from all the spools. It should be understood that the core when used is not rotated, but that the head, which consists of the hollow mandrel, the web-wheels, and the spool-frames and spools carried thereby, rotates continuously in use. Although the head is constantly in rotation, there is no twisting of the strandsuntil they are con` densed at the die. This result is accomplished by means of shaft 25, which is journaled in the web-wheels and carried about by them and to which a rotary movement is imparted wholly independent of the rotation of the web-wheels and gearing intermediate said shaft and rthe spool frames, the action of which is to impart an axial movement to the spool-frames, which just neutralizes the elfect on the spool-frames of the axial movement of thehead. In other words, While the spoolframes are carri-ed about by the head in its rotation they receive through the mechanism just referred to an independent axial movement in the opposite direction from the rotation of the head, the result of 'this compound movement being to retain the spool-frames and spools in a horizontal position at all times as they are carried about by the head and without any twisting whatever of the strands themselves until they are condensed and twisted at the die. It will be noted that as the spool-frames receive their axial move-y ment from the head itself perfect timing of the action of the spool-frames is insured at all times, no matter whether the head may be running fast or slow. As alreadystated, the closeness of the twist of the strands depends upon the speed with which the completed cable is drawn from the machine by the drawing-drum. By that I mean the speed of the drawing-drum relative to the speed of the rotating head. I-f a less amount of twist is required in the strands-that is, if it is required to have the strands liemore nearly parallel to the axis of the cable-,the relative speed of the drawing-drum is increased. If it is desired to give a closer twist to the cablethat is, have the strands lie more oblique tothe axis of the cab1e-the relative speed of the drawing-drum is lessened, it being contemplated that the speed of the rotating head shall be uniform at all times and that the desired changes in the twist of the cable shall be effected through a suitable speed-changing device which controls the speed of the drawing-drum.

Having thus described my invention, I claim l, In a machine of the character described, the combination with a fixed die vthrough which the strands pass of a central rotating mandrel provid ed with a series of web-wheels each having a circular series of spool-frames,v
